TY - JOUR T1 - Small angle X-ray scattering from synthetic Yucca Mountain groundwater colloids AN - 52123610; 2002-028902 AB - We demonstrate the use of small-angle x-ray scattering (SAXS) to characterize groundwater-borne colloids that may be important agents in radionuclide transport from high-level radioactive waste repository. The samples included groundwater from the USGS J-13 well, one of which was treated by heating it to 90 degrees C in contact with crushed Topopah Spring Tuff from the Yucca Mountain site. The SAXS measurements used the UNICAT undulator beamline at the Advanced Photon Source at the Argonne National Laboratory. Power-law plots (scattering intensity verses momentum transfer) were fitted to the SAXS data. Colloids in the untreated J-13 groundwater were shown to have a fractal dimension of nearly 3, whereas colloids in the treated groundwater ("EJ-13") have a dimensionality of approximately 2.4 over a length scale of approximately 3 to 300 nm. Similar power-law plots with dimension 3 characterized concurrent SAXS measurements from aqueous suspensions of Na-montmorillonite and NIST Brick Clay (NBS-67). We attribute these results to the sheet silicate layered structure of the clay colloids present in J-13 well water, montmorillonite, and "brick clay" systems. The differences between EJ-13 and as-received J-13 are perhaps owing to exchange of calcium for sodium with the tuff. Radionuclide incorporation into, adsorption onto, or ion exchange with existing groundwater colloids may promote colloidal transport of radionuclides in groundwater. Such radionuclide-bearing colloids could thereby increase the concentrations of actinides in groundwaters and enhance migration into human-accessible aquifers. Our results demonstrate the application of SAXS to study the physical nature of groundwater colloids essential for understanding phenomena related to colloid stability, size, morphology, aggregation, and adsorption properties.

During the Pleistocene they appear to be important in the waxing and waning of massive continental ice sheets over the Northern Hemisphere, while during earlier ice-free periods the insolation changes are likely important in determining sedimentary deposition, and hence cycles. Defining the effects of maximal and minimal insolation states (relative to mean or "normal" values) is thus of considerable importance. Because the insolation changes vary by latitude and by season, this is, however, not straightforward. Certain orbital configurations will have maximal impact at some latitudes and time of year, but other configurations will be more important for other locations and times. As an example of this, climate model runs (made using the NCAR CCM3) show that maximum effects in the low latitudes occur when tilt (obliquity) is low but eccentricity is high and perihelion occurs in summer. This will lead to a more vigorous monsoon. Minimum effects (e.g., weakest monsoon) will occur when tilt is high, eccentricity is low, and perihelion is in winter. In the high latitudes, maximum effects (e.g., net ice ablation) will occur with high tilt, perihelion in summer, and high eccentricity, while minimum effects (e.g., ice accumulation) will occur with low tilt, perihelion in winter, and high eccentricity. Though these obliquity modifications are essentially second-order effects, they are nonetheless large enough to cause significant changes in the climate model results and hence the timing of local sediment yields relative to sea level changes.

In either case, an important aspect of the planning is the evaluation of the relationships among the expected water use of the phreatophytes, the varying seasonal hydrologic conditions, and the hydrogeologic complexity of the subsurface. Numerical groundwater modeling is well suited for addressing these interactions and providing a basis for the design of a plantation, because such models can account for transient groundwater flux and transpiration, three-dimensional subsurface features, and various hydraulic boundary conditions.This study focuses on the phytoremediation system at Argonne National Laboratory, Argonne, Illinois. Of the 800 hybrid poplars and willows planted in summer 1999, half of them address a groundwater plume downgradient of a source area. Rather than a simple pilot study, this site is complex in terms of both history and hydrogeology. Instead of a surficial unconfined aquifer, the plume is in a thin sand and gravel unit beneath more than 25 feet of low-permeability till; the trees were therefore specially installed in lined, large-diameter boreholes.The resulting calibrated flow model illustrates the necessity of modeling to incorporate the site's hydrology, geology, and water usage, and the solution is applied to evaluating the potential for hydraulic control.

Soil vapor extraction (SVE) systems are a popular, efficient method of remeadiating volatile organic contamination (VOC) in the unsaturated (vadose) zone. However, field installations have shown the initial contaminant extraction rates are high and drop rapidly in an asymptotic manner (long-term tailing behavior). The tailing effect in field SVE systems has been extensively studied. Some believe tailing is caused by complex chemical and physical processes (e.g., nonequilibrium partitioning of the gas phase). Others feel that tailing is produced by complex geology of the field sites. This study demonstrates that the tailing behavior seen at TCAAP is produced by extracting volatile contaminant vapors from VOC contaminated groundwater in the saturated (phreatic) zone. An SVE system with 39 extraction wells was installed and began operation in 1986 at a VOC contaminated site at TCAAP. Approximately 100,000 pounds (45,350 kg) of VOCs were removed. The peak extraction rate was 1,300 pounds (590 kg) per day on the third day of operations. By 1998, the mass removal rate approached a near asymptotic value of about 2 pounds (0.9 kg) per day, nearly three orders of magnitude less than the initial value. A number of phenomena were modeled to determine which was most likely to produce the long-term tailing observed. Most of the simulations resulted in mass removal curves that could approximate the extraction curve for either early or late time. However, the simulations that exhibited long tails did not duplicate the initial rapid drop in extraction rates observed and the simulations that matched the early behavior of the system did not match the long-term behavior. Only simulations which contained contaminated groundwater were able to match observed results. Recent field work supports these findings.

Feldspar-water interactions are characterized by dissolution that is incongruent in acidic but congruent in basic environments. There have been few direct observations of dissolving feldspar surfaces and little is know about the associated molecular scale interfacial processes.We examined (001) orthoclase cleavage surfaces in situ during dissolution under extreme pH conditions using force probe microscope (AFM) and synchrotron radiation. AFM revealed the development of a surface coating following the initial roughening at pH 1.1 and slow solution flow. The coating was not observed when flow became fast, suggesting a possible transport control. Acidic dissolution was characterized by lack of step motion and extensive formation of terrace nanopores. High proton affinity of aluminum surface sites seems responsible for these interfacial processes. At pH 12. 9, step motion and etch pit formation were the dominant dissolution mode without development of surface coating or terrace nanopores, regardless of flow rate. Moreover, monolayer steps were seen to split, indicating the high reactivity of edge sites. X-ray reflectivity, measured as a function of time, showed a characteristic damped oscillatory pattern over a range of temperature and flow rates at low pH, with estimated rates approximately consistent (within 50%) with previous results for powder experiments under steady states. This behavior is indicative of a surface with increased roughness and/or modified termination and implies that surface evolution was uniform over this range of conditions. At high pH, reflectivity exhibited a different pattern indicative of a congruent layer-by-layer mechanism, suggests that surface roughness and composition maintain unchanged during dissolution. These new observations demonstrate that orthoclase dissolution is controlled by at least two distinct pH-dependent mechanisms. The dominant mechanism at low pH is effective across the entire surface, but becomes selectively operative at steps and defects when pH is high. These findings will be discussed in terms of the surface structure of orthoclase.

Climatic conditions can shift relatively large distances (up to 30 degrees latitude) in geologically short intervals (<10 kyrs). As a consequence, substantial, rapid changes can occur in weathering, runoff, lake level and sediment yield within individual drainage basins. Analysis of yield as a function of climate and elevation, determined from modern rivers, indicates that yield from a single drainage area may vary up to seventy times during one orbital cycle, depending on the climatic succession and topography. This would create a distinct sediment supply cycle. Overall, highest yields occur during shifts from arid to subhumid climates. Additionally, weathered sediment can vary from gravel- to clay-dominated during a single climate cycle. Climatic succession and the phase relationships of lake level and sediment supply cycles to orbital cycles are functions of geographic position. Consequently, maximum sediment yield and lake level can occur at any phase of an orbital cycle depending on the climate succession. In addition, because glacioeustatic sea level tends to be in phase with orbital cycles while sediment supply may not be, the phase relationship between sediment and sea level cycles also varies with location. The phase relationship between water level and large amplitude sediment cycles may impact the interpretation of stratigraphy. In sequence stratigraphy, certain lithologies and depositional regimes are associated with specific systems tracts and their inherent timing with respect to sea level. Although recognized as important, variability of lithology caused by changes in sediment yield is generally neglected in application.

However, deficiencies in definitions, analytical methods, procedures and standards in relation to petroleum exploration and production wastes, have limited the flexibility and application of cost-effective innovative technology and treatment methods to the management and disposition of dill cuttings. This paper describes the development of regulatory proposals that allows more flexibility in the management and disposition of drill cuttings while maintaining their hazardous waste classification. These proposals are based on the integration of standard methods used in States in the U.S. and other countries and on proposed soil clean-up standards that are based on carbon fraction methods.

The determination of appropriate residual levels for contaminants at these sites is directly tied to future land use plans and represents the endpoint of concern for many stakeholders. It is also a critical issue for budgeting the cleanup dollars, which are projected to exceed $ 200 billion for the entire program. The concentrations of contaminants to be left behind in soil and water are typically determined by combining applicable standards with the results of site-specific risk assessments. While the U.S. Environmental Protection Agency has promulgated some standards for water, few exist for soil? which has been estimated to account for more than 50 million cubic meters of contaminated material across the DOE complex. Thus, site-specific risk analyses that incorporate relevant exposure scenarios and fate factors are essential to sound decision making. Oversight agencies often pursue conservative assumptions for exposure conditions even when the likelihood is low. For example, large portions of many sites are expected to continue as ecological rather than residential areas, yet cleanup levels are often determined on the basis of assumed residential exposures. Nevertheless, conservative analyses can be used to evaluate the practicability and cost-effectiveness of various cleanup options. At many sites, the consideration of natural attenuation as a reasonable response option for "self-mitigating" radioactive contamination (such as tritium in groundwater) has also been an issue for some oversight agencies, because of a disinclination to support such passive measures in-volving institutional controls over decades to centuries. This paper high-lights several key issues associated with developing cleanup levels at DOE sites and illustrates information for plutonium.

These environmental management decisions have traditionally focused on risks to human and ecological health, without explicit incorporation of sociocultural and economic impacts for local communities. Similarly, current environmental regulations typically define requirements based on individual contaminants in individual media, such as air or water. However, the interrelationships among different resources and potential effects of environmental contaminants are beginning to be acknowledged in environmental protection programs, and a holistic process is emerging for considering impacts across disciplines and over space and time. This paper discusses some of the conceptual issues associated with inte-grating risk and impact assessments for large contaminated sites, as illustrated by application to complex U.S. Department of Energy sites being cleaned up under the Department double prime s environ-mental management program.

The results suggest that atmospheric deposition contributes approximately 80% of the allochthonous input of n-alkanes to Crystal Lake. Atmospheric deposition accounts for about 50% of the total annual input of n-alkanes to Crystal Lake, and an additional 30% is contributed by in situ production of planktonic n-alkanes ( capital sigma C sub(15), C sub(17), C sub(19)). Contributions to the particle dry flux of terrestrial n-alkanes ( capital sigma C sub(25), C sub(27), C sub(29), C sub(31)) by pine pollen dispersal and by dry deposition of particles containing leaf waxes are similar in magnitude and constitute about 60% of the atmospheric input, with particle wet deposition being responsible for the remainder. Approximately 30% of the atmospheric input of the n-alkanes occurs during a two-week episode of pine pollen dispersal in spring. Concentration gradients between gaseous n-alkanes in the atmosphere and dissolved n-alkanes in the water column of Crystal Lake favor volatilization of n-alkanes from the lake surface; however, distributions of dissolved n-alkanes are characteristic of bacteria, and therefore are contained in organic matter and not available for air-water exchange. The estimated net atmospheric input of terrestrial n-alkanes is about 20% less than the settling sediment flux. Additional allochthonous sources of the terrestrial n-alkanes might include diffuse surface runoff or episodes of coarse-particle deposition. The discrepancies in the results from the modeling and mass balance approaches indicate that direct measurements of air-water exchange rates and measurements of the seasonal variations of particle size distributions in air and rain would greatly improve our ability to quantify air-water exchange rates of n-alkanes.

The trend is based on extrapolation of a detailed 1990 inventory, which was constructed as part of the World Bank's RAINS-ASIA project, using IEA energy-use data. The trend shows Asian SO sub(2) emissions growing from 33.7 Tg in 1990 to 39.2 Tg in 1997. Estimates interpolated from the RAINS-ASIA computer model suggest a value for 1997 of 46.4 Tg, assuming no major changes in emission abatement policies after 1990. The reduction in the 1997 value, by some 16%, is primarily due to regulatory requirements and other trends toward lower sulfur content of oil products and coal. A slowdown in the growth of emissions in China - due to a reduction in economic growth, the mining of higher-quality coals, enhanced environmental awareness, and a reduction in industrial coal use - has been instrumental in arresting the growth of Asian emissions. Most of the positive developments have occurred in East Asia, and high-emission growth rates persist in Southeast Asia and the Indian subcontinent. The outlook for the future is that Asian SO sub(2) emissions may well peak in the region of 40-45 Tg by the year 2020 or earlier, in contrast to previous predictions of 2020 emissions as high as 80-110 Tg. The trends developed in this paper are good news for the local and regional environment, particularly in East Asia. However, they also signify lower-than-anticipated concentrations of sulfate aerosol over the Asian continent, with the resulting possibility of greater-than-anticipated regional and global warming.

Because the fuel oil used by ships is high in sulfur, the resulting emissions of SO sub(2) are large and contribute as much as 20% to the atmospheric loading in the vicinity of ports and heavily traveled waterways. Because of the rapid growth of Asian economies in the 1980s and early 1990s, it is estimated that shipping trade grew by an average of 5.4% per year between 1988 and 1995; in particular, crude oil shipments to Asian countries other than Japan grew by an average of 11.4% per year. The emissions of SO sub(2) from shipping are estimated to have grown by 5.9% per year between 1988 and 1995, rising from 545 Gg in 1988 to 817 Gg in 1995. This study uses the ATMOS atmospheric transport and deposition model to study the effects of these emissions, both in absolute terms and relative to land-based emissions, on wet and dry deposition of sulfur. Southeast Asia is most heavily affected by emissions from ships, particularly Sumatra, peninsular Malaysia, and Singapore, which routinely receive in excess of 10% of their deposition from ships. A strong seasonal component is also observed, with large areas of Southeast Asia and coastal Japan receiving sulfur deposition that exceeds 10 mg S m super(-2) season super(-1). Deposition is at least 25% higher in summer and fall than in winter and spring. Peak values of 25-50 mg S m super(-2) season super(-1) are calculated for winter in the Strait of Malacca. This work suggests a need to introduce policies to reduce the sulfur content of marine fuels or otherwise reduce emissions of SO sub(2) from ships in Asian waters.

Resistance schemes used in modeling often perform quite well in daytime conditions over flat terrain. Model results for hilly or mountainous areas, however, are considerably less reliable than those for flat terrain. Even for homogeneous atmospheric and surface conditions and flat terrain, an inadequate model description of surface properties such as vegetative species and soil moisture stress can lead to large differences between modeled and measured fluxes. Third-generation models of mesoscale meteorology and atmospheric chemistry have the potential to achieve several advances, but scaling up of local to regional flux information remains a subject of research. Also, the integrated modeling of gaseous emissions and deposition, which need to be tied together at a low level of model structure, has not yet been accomplished. Many of the processes affecting dry deposition of O sub(3) over individual types of surfaces are fairly well understood. The role of rapid in-air chemical reactions involving NO, NO sub(2), and O sub(3) are difficult to quantify comprehensively, and the effects of water from rain or dew on uptake of gases can be highly variable.

This paper presents estimates of emissions of three of the major air pollutants in China: sulfur dioxide (SO sub(2)), nitrogen oxides (NO sub(x)), and carbon monoxide (CO). Emissions are estimated for each of the 29 regions of China covered by the RAINS-ASIA simulation model, including Hong Kong and Taiwan. All sectors of the Chinese economy are considered, including the combustion of biofuels in rural homes. Data for 1990 and 1995 are presented, as well as two projections for the year 2020 under alternative assumptions about levels of environmental control. Sulfur dioxide emissions are projected to increase from 25.2 mt in 1995 to 30.6 mt in 2020, provided emission controls are implemented on major power plants; if this does not happen, emissions could increase to as much as 60.7 mt by 2020. Emissions of nitrogen oxides are projected to increase from 12.0 mt in 1995 to somewhere in the range of 26.6-29.7 mt by 2020, with little in the way of pollution controls or other emission reduction measures in place. Emissions of carbon monoxide are projected to decline from 115 mt in 1995 to 96.8 mt in 2020, due to more efficient combustion techniques, especially in the transportation sector; if these measures are not realized, carbon monoxide emissions could increase to 130 mt by 2020. Emissions of all three species are concentrated in the populated and industrialized areas of China: the Northeastern Plain, the East Central and Southeastern provinces, and the Sichuan Basin.

Working periods of the subjects ranged from 3 to 24 years, and times from end of work to death ranged from 6 to 31 years. Examination of the distribution of thorium among the organs showed that concentrations in the lung relative to pulmonary lymph nodes, bone or liver were much higher calculated from the dosimetric models in Publication 30 of the International Commission on Radiological Protection (ICRP). Much better agreement was found with more recently proposed models in Publications 68 and 69 of the ICRP.

By 1996, annual energy consumption for light trucks had risen to 5.97 x 10 super(15) Btu [5.97 quadrillion Btu, or "quad," or 6.30 x 10 super(18) joule (J)], compared to 7.94 quad (8.38 x 10 super(18) J) for cars. In recent years (since 1995), the fuel economy of US-manufactured light trucks (almost 99% of which use gasoline engines) has been below the Corporate Average Fuel Economy (CAFE) standards. This paper analyzes a strategy to reduce the CAFE shortfalls by adopting the new, highly energy-efficient clean diesel engine. Research on such engines has been funded by the US Department of Energy, Office of Heavy Vehicle Technologies, under its Light Truck Clean Diesel Engine Program. A clean diesel engine market penetration trajectory is developed, representing an industry response to meet the CAFE standards. Whether the engine will be produced inside the country or imported remains uncertain, so two cases are defined. Values of exports/imports of clean diesel engines/trucks under these cases are estimated. The macroeconomic benefits are estimated by using a model of the US economy developed by Standard & Poor's Data Resources, Inc. On the basis of gains in the gross domestic product projected under the alternative cases, domestic production of the clean diesel engine is favored over importing it.

Peroxyacetyl nitrate (PAN) was observed to exceed 30 ppb during five days of the study, with peroxypropionyl nitrate (PPN) and peroxybutryl nitrate (PBN) reaching 6 and 1 ppb maximum, respectively. Levels of total PANs typically exceeded 10 ppb during the period of measurement and showed a very strong diurnal variation with PANs maximum during the early afternoon and falling to less than 0.1 ppb during the evening hours. These levels of PANs are the highest reported values in North America (and the world) for an urban center, since levels of approximately 30 ppb were reported during the late 1970s in the Los Angeles area. Hydrocarbon measurements indicate that the levels of olefins, specifically butenes are significant in Mexico City. A time series taken of source indicator hydrocarbons taken before and during a Mexican National Holiday with reduced automobile traffic clearly show that mobile sources of butenes are as important as liquefied petroleum gas. Observations of 10-40 ppb C methyl-t-butyl ether (MTBE) are consistent with MTBE/gasoline fuel usage as a source of isobutene and formaldehyde. Both these reactive species can lead to increased oxidant and PAN formation. These calculations indicate that megacities can be important sources of both primary and secondary pollutants, and that PANs produced in megacity environments are likely to contribute strongly to regional scale ozone and aerosol productions during long range transport.

Diesel exhaust and fugitive dust emissions from vehicles transporting hazardous shipments lead to increased air pollution, which increases the risk of latent fatalities in the affected population along the transport route. The estimated risk from these vehicle-related sources can often be as large or larger than the estimated risk associated with the material being transported. In this paper, data from the U.S. Environmental Protection Agency's Motor Vehicle-Related Air Toxics Study are first used to develop latent cancer fatality estimates per kilometer of travel in rural and urban areas for all diesel truck classes. These unit risk factors are based on studies investigating the carcinogenic nature of diesel exhaust. With the same methodology, the current per-kilometer latent fatality risk factor used in transportation risk assessments for heavy diesel trucks in urban areas is revised and the analysis expanded to provide risk factors for rural areas and all diesel truck classes. These latter fatality estimates may include, but are not limited to, cancer fatalities and are based primarily on the most recent epidemiological data available on mortality rates associated with ambient air PM-10 concentrations.

AN - 70829590; 10527156 AB - A process to implement the U.S. Department of Energy's (DOE) policy for authorized release of radioactive materials from DOE facilities is provided in the Draft Handbook for Controlling Release for Reuse or Recycle of Property Containing Residual Radioactive Material, published by DOE in 1997 and distributed to DOE field offices for interim use and implementation. The authorized release of such property is intended to permit its beneficial use across the entire DOE complex. A computerized management tool--P2Pro(RSM)--has been developed to aid in carrying out the release process for radioactive metals. It contains protocols for the authorized release process and relevant information to facilitate the evaluation of scrap metals for reuse and recycle. The P2Pro(RSM) protocols provide DOE and its contractors with an effective, user-friendly tool for managing authorized release activities P2Pro(RSM) is designed to be used in the Windows environment. The protocols incorporate a relational database coupled with a graphic-user interface to guide the user through the appropriate steps so authorized release limits can be developed. With the information provided in the database, an as-low-as-reasonably-achievable (ALARA) optimization process can be easily set up and run for up to 10 alternatives for disposition of radioactive scrap metals. The results of the ALARA optimization process can be printed in a series of reports and submitted as part of the application for the authorized release of the radioactive scrap metals.

AN - 70829332; 10527152 AB - The Argonne National Laboratory-East (ANL-E) Environmental Radiation Monitoring System measures and records ambient radiation levels and provides detection capability for radon decay products in rain clouds. These decay products in rainwater tracked into a facility on the shoes of workers can cause false alarms from hand and shoe monitors. The monitors at ANL-E can easily detect the radon decay products, and the 19.6 and 26.8 min half-lives of the beta-particle emitters are long enough in many cases for sufficient activity to still be present to initiate a contamination alarm when the shoes are checked for radioactivity. The Environmental Radiation Monitoring System provides a warning when precipitation contains elevated levels of radon decay products. It is based on a prototype developed at the Super Collider Laboratory. During its first year of operation there were nine alarms from radon decay products with an alarm trigger point set at 30% greater than background. The alarms occurred at both monitoring stations, which are approximately 1,000 m apart, indicating large diameter radon clouds. The increases in background were associated with low atmospheric pressure. There was no correlation with radon released from the coal-burning steam plant on the site. Alarms also occurred when short-lived accelerator-produced radioactivity in the exhaust stack plume passed over the NaI(Tl) detector in one of the stations. The 450 MeV proton accelerator near the station produced 12C, 13N, and 15O by spallation of air nuclei. The gamma-ray spectrum from the plume from the accelerator exhaust stack was dominated by the 511 keV annihilation gamma rays from decay of these radionuclides. These gamma rays were easily distinguished from the 609 keV, 1,120 keV, and 1,764 keV gamma rays emitted by the radon decay products.

Urban areas occupied a minimum of 3.6%, 4.7%, and 5.7% of the Nile Delta in 1972, 1984, and 1990, respectively, an increase of 58% in 18 years. Approximately half of this increase occurred between 1984 and 1990. If this trend continues, Egypt could lose 12% of its total agricultural area to urbanization by 2010. Despite the fact that growth is pronounced around the cities, it is the growth around the thousands of small villages that poses the largest threat to the agricultural productivity of the Nile Delta. The cumulative growth rate for the cities and large villages between 1972 and 1990 is 37%, and that for the small villages is 77% for the same time period.

From these measurements, details are presented on the in situ structure, bonding, adsorption and growth mechanisms on the monolayers, and the approach can be applied to the interaction of organic molecules with mineral surfaces in aqueous systems.

It is estimated that biofuels contributed 573 Tg-C (teragrams of carbon; 1 Tg = 10 super(12) g) in 1990, about 28% of the total carbon emissions from energy use in Asia. China (259 Tg-C) and India (187 Tg-C) were the largest emitting countries. The majority of the emissions, 504 Tg-C, were in the form of CO sub(2); however, emissions of non-CO sub(2) greenhouse gases were significant: 57 Tg-C as CO, 6.4 Tg-C as CH sub(4), and 5.9 Tg-C as NMHC. Because of the high rates of incomplete combustion in typical biofuel stoves and cookers and the high global warming potentials (GWP) of the products of incomplete combustion (PICs), biofuels comprise an even larger share of energy-related emissions when measured in terms of total GWP (in CO sub(2) equivalents): 38% over a 20-year time horizon and 31% over a 100-year time horizon. Even when the biofuel is assumed to be harvested on a completely sustainable basis (all CO sub(2) emissions reabsorbed in the following growing season), PIC emissions from biofuel combustion account for 4.5% of the total carbon emissions and 23% of CO sub(2) equivalents on a short-term (20-year) GWP basis.

The structure of wyartite, CaU (super 5+) (UO (sub 2) ) (sub 2) (CO (sub 3) )O (sub 4) (OH)(H (sub 2) O) (sub 7) , Z = 4, orthorhombic, a = 11.2706(8), b = 7.1055(5), c = 20.807(1) Aa, V = 1666.3(3) Aa (super 3) , space group P2 (sub 1) 2 (sub 1) 2 (sub 1) , was solved by direct methods and refined to an agreement index (R) of 4.9% for 2309 unique reflections collected using MoKalpha X-radiation and a CCD-based detector. The structure contains three unique U positions; two contain U (super 6+) and involve uranyl ions with typical pentagonal-bipyramidal coordination. Seven anions coordinate the other U position, but there is no uranyl ion present. The polyhedral geometry, the bond-valence sum incident at this U site, and electroneutrality requirements, all indicate that this site contains U (super 5+) The Uphi (sub 7) (phi : O, OH, H (sub 2) O) polyhedra share edges and corners to form a unique sheet in which a CO (sub 3) group shares an edge with the U (super 5+) phi (sub 7) polyhedron. The structure contains one Ca site coordinated by seven anions. The Ca atom and its associated H (sub 2) O groups occupy interlayer sites, along with two H (sub 2) O groups that are held in the structure by H bonds only. The Caphi (sub 7) polyhedron is linked to one adjacent sheet by sharing an edge with the CO (sub 3) group and an O atom with a U (super 6+) phi (sub 7) polyhedron. Structural units are linked together through hydrogen bonds only.

Whereas water has not been positively found, a large number of studies have established the presence of Hg in lunar samples. Its presence and volatile behavior are important when considering water as probably the most important in situ lunar resource. Here we show that the amount of Hg in lunar cold traps may be comparable to the amounts of water.

These (plus prior RNAA data) provide a compositional database of 92 H4-6 chondrite falls. Three suites of samples can be identified from their noble gas contents: 44 with "normal" contents and, therefore, "normal" orbits and cosmic-ray exposure histories; 8 that lost radiogenic gases, presumably by shock late in their histories; and 17 that lost cosmogenic gases by heating during close solar approach. We used the standard multivariate statistical techniques of linear discriminant analysis and logistic regression to compare contents of the 10 moderately and highly volatile trace elements, listed above, in these three suites. We found no significant differences. This contrasts sharply with similar comparisons involving random falls and H4-6 chondrites that landed on Earth at specific time intervals. Apparently, contents of volatile trace elements in H4-6 chondrites were established early in their histories, and they are so retentively sited that loss during later heating episodes did not occur.

Recent measurements of nitrogenated and oxygenated hydrocarbons in the upper troposphere and lower stratosphere have revealed the possibility of significant perturbation of this region. A zonally averaged 2-D chemical transport model enhanced to represent tropospheric processes was used to explore the extent of this perturbation on global and regional spatial scales and on seasonal and annual average timescales. Acetone was shown to cause a significant increase in the HO sub(x) budgets of the upper troposphere in the midlatitude Northern Hemisphere during the winter and early spring months, with acetone photolysis providing the most significant source of HO sub(x) radicals. The tropical upper troposphere has a uniform increase in HO sub(x) of up to 20% throughout the year because of acetone photolysis. Including the hydrocarbons caused a net increase in ozone of 5 ppbv in the lower and middle troposphere and 5-10 ppbv in the upper troposphere for global and annual averages. The effect of including the hydrocarbons on the calculated model ozone response for the case of doubled surface mixing ratios of atmospheric CH sub(4) is also discussed. It is shown that including hydrocarbons in the model has a significant effect on the modeled ozone response to the methane increase. JF - Journal of Geophysical Research. D.

Isoprene emissions from the deciduous forest canopy were estimated by coupling an existing biogenic emission algorithm with estimates of canopy leaf density inferred from satellite remote sensing observations. Numerical simulations predicted low isoprene concentrations in the middle and upper ABL; however, the agreement between the simulations and the measured values was poor for two of the three profiles, indicating that a three-dimensional transport model might be necessary in future simulations. Chemical oxidation of isoprene by O sub(3) and hydroxyl radical (OH), particularly in the middle and upper ABL, tends to reduce the isoprene concentrations and influences the vertical fluxes in that layer; however, chemical reactions have little effect on fluxes of isoprene near the emission source, where turbulent mixing is much faster than chemical reactions and where the emission process controls the vertical flux. The isoprene flux decreases rapidly with increasing height, with little isoprene escaping from the ABL. Vertical profiles of methanol concentrations were simulated with the biogenic emission algorithm used for isoprene; these vertical profiles were similar to the measured values for the well-mixed ABL but were much lower than the measured concentrations in the lower layers of the growing ABL because of weaker calculated mixing in the upper ABL during the morning. The results of this investigation indicate that chemical oxidation of isoprene is rapid enough to allow O sub(3) and other oxidants to accumulate in the ABL on a regional scale if sufficient levels of nitrogen oxides are present; however, methanol is much more stable, and biogenic emissions of this compound have the potential to form O sub(3) and other oxidants in areas distant from the emission source.

Simulations for four seasons are conducted: February, April, August, and October. The predicted results of summer and winter are compared to measured concentration of SO sub(2), sulfate, and sulfate wet deposition in Japan. Further comparison of sulfate wet deposition to observations in China is made to assess the general performance of the model. The study shows that wet deposition is more important than dry deposition. It is the predominant factor in each of these four months. It is also found that rainout process, compared to washout process, make a larger contribution to sulfate wet deposition in summer and spring than in the dry months, such as October. The total sulfur wet to dry deposition ratio is 1.6 in February, 1.2 in April, 2.9 in August, and 1.9 in October.

We characterize the loss of potential productive output due to environmental constraints, decomposing losses into those resulting from the commitment of capital to pollution abatement and those losses that arise from other sources. We also assess the potential for improvements that increase productivity and reduce pollution. Results from the paper industry show a "win-win" potential for inputs and pollution to be simultaneously reduced by 2% to 8%, without reducing productivity. We also find that environmental constraints reduce production by 9%, a quarter of which results from pollution abatement capital constraints.

The results for pH 3 solutions show that all growth rates obey the same linear function of saturation state provided that the reactive surface area is evaluated for each mineral substrate. This suggests that the dominant nucleation and growth mechanisms are two-dimensional. Kaolinite and muscovite appear to provide epitaxial templates for the growth of gibbsite, although epitaxy may occur only on the edges of kaolinite where there is pH-dependent surface charge, and on both the basal and edges of muscovite where there are permanent and pH-dependent charge, respectively.

The discussions of this group, which was intermittently composed of a combination of model-building, model-using, and nonmodeling geologists, centered on the type and quality of common geological observations, the scales of these observations, and the accurate representation of observations in geological models. The underlying concerns were whether all relevant processes are accounted for in existing models, and whether modelers are using the available models correctly, inputting realistic values and ranges of values at the proper scales. Our fundamental questions include the following: How closely is the variability of geological observations reflected in stratigraphic models? If such variability is well represented within a model, how well does a simulation predict away from points of control? If it does not do this well, is it the input parameters that are not reflecting the natural variability of the system, or does the fault lie with the model itself? If the model itself is the limiting factor, how well do we really need to constrain input parameters? How well do we understand the nonlinear characteristics of natural systems, and how are these characteristics introduced into models?

A radioactive glass was also reacted under intermittent flow conditions. Colloidal and suspended glass alteration particles in the leachates were examined using analytical TEM. The major colloidal phase identified in all tests was partially crystalline dioctahedral smectite clay. Clay colloids were stable at S/V ratios of 340 and 2000/m but at 20 000/m they flocculated and sedimented. Calcite, dolomite and transition metal oxide particles were more common in the intermittent flow tests but were also found in the static tests. Layered Mn minerals, birnessite and asbolane were found exclusively in the intermittent tests; weeksite and a U-Ti phase was found exclusively in the static tests. Partially crystalline REE-bearing calcium phosphate colloids, structurally similar to rhabdophane, were found in both types of tests; these particles exhibited a negative Ce anomaly. Geochemical modelling indicated that Pu should be present predominantly as a carbonate rather than a phosphate phase but this may be due to the paucity of suitable thermodynamic data available to the model.

IMPDH inhibitors have clinical utility as antiviral, anticancer or immunosuppressive agents. The essential nature of this enzyme suggests its therapeutic applications may be extended to the development of antimicrobial agents. Bacterial IMPDH enzymes show biochemical and kinetic characteristics that are different than the mammalian IMPDH enzymes, suggesting IMPDH may be an attractive target for the development of antimicrobial agents. We suggest that the biochemical and kinetic differences between bacterial and mammalian enzymes are a consequence of the variance of specific, identifiable amino acid residues. Identification of these residues or combination or residues that impart this mammalian or bacterial enzyme signature is a prerequisite for the rational identification of agents that specifically target the bacterial enzyme. We used sequence alignments of IMPDH proteins to identify sequence signatures associated with bacterial or eukaryotic IMPDH enzymes. These selections were further refined to discern those likely to have a role in catalysis using information derived from the bacterial and mammalian IMPDH crystal structures and site-specific mutagenesis. Candidate bacterial sequence signatures identified by this process include regions involved in subunit interactions, the active site flap and the NAD binding region. Analysis of sequence alignments in these regions indicates a pattern of catalytic residues conserved in all enzymes and a secondary pattern of amino acid conservation associated with the major phylogenetic groups. Elucidation of the basis for this mammalian/bacterial IMPDH signature will provide insight into the catalytic mechanism of this enzyme and the foundation for the development of highly specific inhibitors.

Difference-Fourier maps show a double minimum between adjacent O(10) atoms along c, indicating a statistical distribution of H(2) between two sites. The partial occupancy of the H(1) site is consistent with the substitution of F for O at the O(11) site. Although hydrogrossular and vesuvianite have similar structures and occur in the same environments, the neutron-diffraction results rule out the possibility of a hydrogarnet-type substitution [(O (sub 4) H (sub 4) ) (super 4-) = (SiO (sub 4) ) (super 4-) ] in this specimen.

S. Environmental Protection Agency's Great Lakes National Program Office has conducted an annual program of water quality monitoring in the middle Great Lakes (Lakes Erie, Huron, and Michigan) since 1983. Sampling in Lake Ontario and Lake Superior was added in 1985 and 1992 respectively. The annual monitoring program, which was designed to meet some of the surveillance requirements of the 1978 U. S.-Canada Water Quality Agreement, evolved from an earlier water quality surveillance plan that called for intensive surveys of each of the Great Lakes every five years. While the five-year sampling plan was intensive both in terms of spatial coverage and temporal resolution, some results indicated that natural variations in water quality might exceed attributable to control efforts and that these variations could not be quantified by sampling every five years. The work to be presented here was intended to determine whether the sampling network satisfied its original design requirement of being representative of the well-mixed open waters of the Great Lakes and whether any long-term trends in Great Lakes water quality could be detected.

AN - 69843001; 10379036 AB - The current state of the art regarding the use of chelating agents to extract heavy metal contaminants has been addressed. Results are presented for treatability studies conducted as worst-case and representative soils from Aberdeen Proving Ground's J-Field for extraction of copper (Cu), lead (Pb), and zinc (Zn). The particle size distribution characteristics of the soils determined from hydrometer tests are approximately 60% sand, 30% silt, and 10% clay. Sequential extractions were performed on the 'as-received' soils (worst case and representative) to determine the speciation of the metal forms. The technique speciates the heavy metal distribution into an easily extractable (exchangeable) form, carbonates, reducible oxides, organically-bound, and residual forms. The results indicated that most of the metals are in forms that are amenable to soil washing (i.e. exchangeable+carbonate+reducible oxides). The metals Cu, Pb, Zn, and Cr have greater than 70% of their distribution in forms amenable to soil washing techniques, while Cd, Mn, and Fe are somewhat less amenable to soil washing using chelant extraction. However, the concentrations of Cd and Mn are low in the contaminated soil. From the batch chelant extraction studies, ethylenediaminetetraacetic acid (EDTA), citric acid, and nitrilotriacetic acid (NTA) were all effective in removing copper, lead, and zinc from the J-Field soils. Due to NTA being a Class II carcinogen, it is not recommended for use in remediating contaminated soils. EDTA and citric acid appear to offer the greatest potential as chelating agents to use in soil washing the Aberdeen Proving Ground soils. The other chelating agents studied (gluconate, oxalate, Citranox, ammonium acetate, and phosphoric acid, along with pH-adjusted water) were generally ineffective in mobilizing the heavy metals from the soils. The chelant solution removes the heavy metals (Cd, Cu, Pb, Zn, Fe, Cr, As, and Hg) simultaneously. Using a multiple-stage batch extraction, the soil was successfully treated passing both the Toxicity Characteristics Leaching Procedure (TCLP) and EPA Total Extractable Metal Limit. The final residual Pb concentration was about 300 mg/kg, with a corresponding TCLP of 1.5 mg/l. Removal of the exchangeable and carbonate fractions for Cu and Zn was achieved during the first extraction stage, whereas it required two extraction stages for the same fractions for Pb. Removal of Pb, Cu, and Zn present as exchangeable, carbonates, and reducible oxides occurred between the fourth- and fifth-stage extractions. The overall removal of copper, lead, and zinc from the multiple-stage washing were 98.9%, 98.9%, and 97.2%, respectively. The concentration and operating conditions for the soil washing extractions were not necessarily optimized. If the conditions had been optimized and using a more representative Pb concentration (approximately 12000 mg/kg), it is likely that the TCLP and residual heavy metal soil concentrations could be achieved within two to three extractions. The results indicate that the J-Field contaminated soils can be successfully treated using a soil washing technique.

AN - 69840055; 10379033 AB - The Mound laboratory site in Miamisburg, OH, a former plutonium processing facility, contains approximately 40000 yd(3) (30,580 m3) of plutonium- and thorium-contaminated soils and sediments at levels that require remediation. Existing applicable remediation technologies are unsatisfactory, because they are expensive and do not provide volume reduction. ACT*DE*CON is a chemical soil leaching technology for the treatment of soils that utilizes contaminant dissolution via dilute selective solutions to remove radionuclides. In bench-scale tests, process parameters were developed for the optimal treatment of the Miami Erie Canal soil at the Mound site, combining the maximum plutonium removal with an acceptable amount of soil dissolution and minimizing the costs of reagents. Parameters evaluated included soil to extractant mass ratio, temperature, rinse solution composition, kinetics, and the application of several dewatering aids. Plutonium removal rates of >95% were achieved, and the residual plutonium in the treated soil proved to be very immobile-confirming that the process had removed the most accessible species of the radionuclide. Currently being tested at Mound is an engineering scale-up that includes an attrition scrubber, a counter-current extractor, and a reverse osmosis system. Economic evaluations based on bench-scale results put the treatment cost at US$278/yd(3) (US$364/m3), compared to US$350/yd(3) (US$458/m3) for the 'box-and-bury' baseline alternative treatment system.

Five chlorinated ethylenes including tetrachloroethylene (PCE), trichloroethylene (TCE), and three isomers of dichloroethylenes (DCEs) were examined. The degradation process was rapid with pseudo-first-order rate constants ranging from 4.5 x 10 super(-5) to 0.03 s super(-1) at MnO super(-) sub(4) = 1 mM. The rate increased with a decreasing number of chlorine substituents on the ethylene. The higher reactivity of trans-DCE (k sub(obs) = 30 x 10 super(-3) s super(-1) at MnO super(-) sub(4) = 1 mM) as compared to cis-DCE (k sub(obs) = 0.9 x 10 super(-3) s super(-1) at MnO super(-) sub(4) = 1 mM) is thought to be caused by a significant steric effect due to the formation of a large cyclic activated complex. TCE oxidation as a second-order reaction was confirmed and the rate constant, k = 0.67 plus or minus 0.03 M super(-1) s super(-1), is independent of pH over the range of 4-8. The activity of both C1 super(-1) and hydrogen ions was monitored over time and suggests essentially complete dechlorination, making the degradation products less harmful than the parent compounds. Competition for MnO super(-) sub(4) from other organic compounds in ground water or highly contaminated ground water was also evaluated in experiments. A simple and quick approach was demonstrated to estimate permanganate consumption by other organic compounds for field applications and to predict the TCE degradation rate in a system involving multiple contaminants.

This study surveyed 23 species of Carex occurring in upland and wetland habitats in northeastern Illinois. Mycorrhizal infection by arbuscular fungi was found in the roots of 16 species of Carex and appears to occur in response to many factors, both environmental and phylogenetic. While some species appear to be obligately nonmycorrhizal, edaphic influences may be responsible for infection in others. In five of the seven Carex species that were nonmycorrhizal, a novel root character, the presence of bulbous-based root hairs, was identified. The taxonomically patchy distribution of the distinctive root hair trait suggests that these structures may have evolved several times within the genus. Evidence of multiple independent origins of the root hair trait lends support to the hypothesis that root hairs represent an adaptation to nonmycotrophy. Although taxonomic position does seem to be of importance in determining the mycorrhizal dependence of sedges, the pattern may be a patchwork of both mycorrhizal clades and clades that have adapted to the nonmycorrhizal state.

To provide a basis for the evaluation of IMPDH inhibitors as antimicrobial agents, we have expressed and characterized IMPDH from the pathogenic bacterium Streptococcus pyogenes. Our results show that the biochemical and kinetic characteristics of S. pyogenes IMPDH are similar to other bacterial IMPDH enzymes. However, the lack of sensitivity to mycophenolic acid and the K sub(m) for NAD (1180/ mu M) exemplify some of the differences between the bacterial and mammalian IMPDH enzymes, making it an attractive target for antimicrobial agents. To evaluate the basis for these differences, we determined the crystal structure of the bacterial enzyme at 1.9 Ae with substrate bound in the catalytic site. The structure was determined using selenomethionine-substituted protein and multiwavelength anomalous (MAD) analysis of data obtained with synchrotron radiation from the undulator beamline (19ID) of the Structural Biology Center at Argonne's Advanced Photon Source. S. pyogenes IMPDH is a tetramer with its four subunits related by a crystallographic 4-fold axis. The protein is composed of two domains: a TIM barrel domain that embodies the catalytic framework and a cystathione beta -synthase (CBS) dimer domain of so far unknown function. Using information provided by sequence alignments and the crystal structure, we prepared several site-specific mutants to examine the role of various active site regions in catalysis. These variants implicate the active site flap as an essential catalytic element and indicate there are significant differences in the catalytic environment of bacterial and mammalian IMPDH enzymes. Comparison of the structure of bacterial IMPDH with the known partial structures from eukaryotic organisms will provide an explanation of their distinct properties and contribute to the design of specific bacterial IMPDH inhibitors.

AN - 69643064; 10091653 AB - The most common form of systemic amyloidosis originates from antibody light chains. The large number of amino acid variations that distinguish amyloidogenic from nonamyloidogenic light chain proteins has impeded our understanding of the structural basis of light-chain fibril formation. Moreover, even among the subset of human light chains that are amyloidogenic, many primary structure differences are found. We compared the thermodynamic stabilities of two recombinant kappa4 light-chain variable domains (V(L)s) derived from amyloidogenic light chains with a V(L) from a benign light chain. The amyloidogenic V(L)s were significantly less stable than the benign V(L). Furthermore, only the amyloidogenic V(L)s formed fibrils under native conditions in an in vitro fibril formation assay. We used site-directed mutagenesis to examine the consequences of individual amino acid substitutions found in the amyloidogenic V(L)s on stability and fibril formation capability. Both stabilizing and destabilizing mutations were found; however, only destabilizing mutations induced fibril formation in vitro. We found that fibril formation by the benign V(L) could be induced by low concentrations of a denaturant. This indicates that there are no structural or sequence-specific features of the benign V(L) that are incompatible with fibril formation, other than its greater stability. These studies demonstrate that the V(L) beta-domain structure is vulnerable to destabilizing mutations at a number of sites, including complementarity determining regions (CDRs), and that loss of variable domain stability is a major driving force in fibril formation.

Fueled by high population growth and vibrant economies, energy consumption is currently 12% of the world's total and projected to increase by a factor of 2 to 3 by 2030. Because fossil fuels will provide much of this energy, emissions of sulfur dioxide are projected to increase by about the same amount. Northeast China is the main emitting region, and sulfur is transported across the Korean peninsula to Japan and beyond. Acid deposition is evident today and will increase dramatically in the future. It is projected that severe damage to ecosystems will occur throughout the region without the introduction of emission controls. Abatement technology could cost USD 10-30 billion annually by 2030 and still provide only partial protection. There is an urgent need for regional cooperation to improve the level of scientific understanding and develop a basis for regionwide control strategies.

Incoherent quasi-elastic neutron scattering (QENS) was used to measure the translational and rotational mobility of water in the clays, while chilled mirror dewpoint psychrometry measured water activity of the samples, differential scanning calorimetry (DSC) provided information about the temperature of dehydration and X-ray diffraction (XRD) quantified layer spacings for the clays. The neutron scattering data were fit to a jump diffusion model that yielded mean jump lengths, jump diffusion residence times and rotational relaxation times for water in the clays. Mean jump lengths were quite similar for the 2 different cation saturations at equivalent water contents, and decreased with increasing water content. The fitted jump lengths ranged from 0.27-0.5 nm and were 2-4 times larger than that found for bulk water (0.13 nm). Jump diffusion residence times were 3-30 times longer than that for bulk water (1.2 ps) and also decreased with increasing water content. The residence times were somewhat shorter for HDTMA-clay as compared with Ca-clay at equivalent water contents. Rotational motion was less strongly influenced than translational motion by the presence of the clay surface. The energy state of water in the 2 cation saturations were quite different; dehydration temperatures for the HDTMA-clay were approximately 30 degrees C lower than the Ca-clay at equal water contents, while water activities, as P/P (super 0) , were up to 0.6 units higher. A linear relationship was found between water activity and the translational diffusion coefficient, although at the highest water content, the diffusion coefficient of water for the HDTMA-clay was approximately 30% higher than that measured for bulk water.

Two related aspects were investigated: We attempted to apply quantitative methods to calculate the reactivity using the hydroxyl absorption bands and to calculate the total alkyl or acyl groups incorporated using specific coal bands. The latter work showed that the use of IR coal bands to determine the amount of added groups can only be used qualitatively due to unpredictable changes in the coal band intensities. Quantitative monitoring of the hydroxyl groups showed that, in some reactions, more hydroxyl was found in the coal after reaction, suggesting that there was little reaction and mostly trapping of hydrolyzed reagent into the coal.

An object undergoing lateral motion while in contact with a second object can either roll or slide. The resulting energy loss and mechanical wear depend largely on which mode of motion occurs. At the macroscopic scale, rolling is preferred over sliding, and it is expected to have an equally important role in the microscopic domain. Although progress has been made in our understanding of the dynamics of sliding at the atomic level, we have no comparable insight into rolling owing to a lack of experimental data on microscopic length scales. Here we produce controlled rolling of carbon nanotubes on graphite surfaces using an atomic force microscope. We measure the accompanying energy loss and compare this with sliding. Moreover, by reproducibly rolling a nanotube to expose different faces to the substrate and to an external probe, we are able to study the object over its complete surface.

AN - 69554507; 9886414 AB - We examined the role of fibronectin (FN) and FN-binding integrins in macrophage differentiation. Increased FN and alpha5beta1 integrin gene expression was observed in phorbol 12-myristate 13-acetate PMA-treated HL-60 cells and PMA- or macrophage-CSF-treated blood monocytes before the manifestation of macrophage markers. After treatment of HL-60 cells and monocytes, newly synthesized FN was released and deposited on the dishes. An HL-60 cell variant, HL-525, which is deficient in the protein kinase Cbeta (PKC-beta) and resistant to PMA-induced differentiation, failed to express FN after PMA treatment. Transfecting HL-525 cells with a PKC-beta expression plasmid restored PMA-induced FN gene expression and macrophage differentiation. Untreated HL-525 cells (which have a high level of the alpha5beta1 integrin) incubated on FN differentiated into macrophages. The percentage of cells having a macrophage phenotype induced by PMA in HL-60 cells, by FN in HL-525 cells, or by either PMA or macrophage-CSF in monocytes was reduced in the presence of mAbs to FN and alpha5beta1 integrin. The integrin-signaling nonreceptor tyrosine kinase, p72Syk, was activated in PMA-treated HL-60 and FN-treated HL-525 cells. We suggest that macrophage differentiation involves the activation of PKC-beta and expression of extracellular matrix proteins such as FN and the corresponding integrins, alpha5beta1 integrin in particular. The stimulated cells, through the integrins, attach to substrates by binding to the deposited FN. This attachment, in turn, may through integrin signaling activate nonreceptor tyrosine kinases, including p72Syk, and later lead to expression of other genes involved in evoking the macrophage phenotype.

Transformation kinetics were measured on aging metal-ferrihydrite co-precipitates using selective extraction of ferrihydrite with physical characterization of the aged solid. The influence that Ni and Pb exerted on the crystallization process was metal-specific and inconsistent with predictions based on model-derived stabilities for the metal-ferrihydrite sorption complex. Pb did not retard ferrihydrite transformation to a greater extent than Ni. Sorbed Pb primarily existed as an inner-sphere surface complex in aged solids. The results have important implications for determining the role that ferrihydrite and other metastable sorbent phases may have in controlling metal cycling in the environment.

Uranyl silicates have also been identified as alteration phases on hydrated actinide-bearing borosilicate waste glass. In both cases, the expected paragenesis is similar to that found in natural analogues, and includes the uranyl silicate minerals boltwoodite, uranophane, weeksite and haiweeite. These minerals may incorporate environmentally important fission products such as (super 135) Cs, (super 137) Cs and (super 90) Sr, and actinides such as Np and Am, thus becoming the source term for these radionuclides. We are investigating the incorporation of radionuclides into uranyl silicates by synthesis experiments, ion exchange experiments, and crystal structure studies of natural and synthetic crystals. Boltwoodite, a hydrated K-Na uranyl silicate, may impact upon the mobility of Cs and Sr. The structure contains sheets of uranyl and silicate polyhedra, with low-valence cations and H (sub 2) O groups in the interlayers. Ion exchange experiments have demonstrated that the interlayer cations can be readily exchanged with Cs. Synthesis of a Sr-substituted boltwoodite, in which half of the K cations have been replaced by Sr, has been demonstrated by structure determination. The structure of the new compound KNa (sub 3) (UO (sub 2) ) (sub 2) (Si (sub 4) O (sub 10) ) (sub 2) (H (sub 2) O) (sub 4) , that formed during vapor hydration of an actinide-bearing borosilicate waste glass, contains sheets of four- and eight-membered vertex-sharing silicate tetrahedra linked into an open framework by sharing polyhedral elements with uranyl square bipyramids. Large channels and voids in the structure contain low-valence cations and H (sub 2) O groups.

This disposal will require the development of a multi-barrier engineered disposal system that will effectively isolate waste radionuclides from the biosphere for a period of 100,000 years or more. Radionuclides contained in spent fuel represent the largest curie content inventory for any nuclear waste form in the United States due to the large volume of spent fuel that currently exists and the high concentration of radionuclides associated with the spent fuel rods. Alteration phases may exert strong controls on the corrosion behavior of spent nuclear fuel and the release of contained radionuclides. Several studies looking at the long-term corrosion of synthetic uranium oxide, spent nuclear fuel, and naturally weathered uraninite indicate that a paragenetic sequence of uranyl alteration phases will occur in the following order: uraninite, schoepite group phases, alkali+alkaline earth uranyl-oxide hydrates, uranyl silicates, and finally, alkali+alkaline earth uranyl silicates. Experimental studies have also demonstrated that a large proportion of radionuclides contained in spent fuel, including isotopes of Cs, Sr, Mo, Np, Ce, and Nd (the latter two as surrogates for Pu and Am, respectively) may be incorporated in these phases, thereby significantly retarding their migration following the alteration of spent nuclear fuel.

As radiogenic Pb accumulates in a mineral, U content must decrease concomitantly. The combination of these two effect can destabilize many U-mineral structures. Under reducing conditions, Pb released from U minerals commonly forms galena, which has a larger molar volume than uraninite (52.4 Aa3/mol and 40.4 Aa3/mol, respectively). Precipitation of galena within uraninite can strain the host crystal, helping to break it apart and provide pathways for groundwater infiltration. re-crystallization of uraninite caused by accumulation of radiogenic Pb results in a net volume decrease of the original uraninite, without necessarily any loss of U to groundwater. Under oxidizing conditions, Pb can combine with uranyl ions to form one or more of approximately 30 Pb-uranyl minerals. Accumulation of radiogenic Pb can cause continual re-crystallization of uranyl minerals. Precipitation of Pb-uranyl minerals within a nominally Pb-free host with the same or similar structure can produce crystallographically oriented inclusions of Pb-uranyl minerals that may confuse analytical interpretations, helping to explain conflicting or inconsistent structural and chemical data for several uranyl minerals. Due to the different mobilities of Pb and U in most groundwaters, Pb-bearing uranyl minerals dissolve incongruently, releasing some U while locally retaining Pb in newly formed uranyl minerals. By stabilizing U-bearing solids, radiogenic Pb can substantially reduce the mobility of U the alteration of uranyl minerals in most groundwaters. The earliest Pb-uranyl minerals to form in most U deposits undergoing oxidation have relatively low Pb:U ratios. Subsequent and continued interaction with groundwater leads to the formation of increasingly Pb-enriched uranyl minerals, such as curite or wolsendorfite. The continued interaction of such Pb-rich minerals with groundwater may help to further limit U migration by providing nucleation sites for late-stage alteration minerals.

It is a particularly characteristic phase in the old (approximately 600 Ma) lithium pegmatites of the Mozambique Belt in East Africa, where large euhedral microlite occurs in association with albite, spodumene and lithian mica. We have examined a sample from a strongly altered pegmatite at Mina Conco, Mozambique. Here, microlite exhibits a pronounced growth zoning, with a U-free core surrounded by a U-rich rim (UO (sub 2) up to 13 wt. %). The core exhibits a conjugate set of straight fractures which provided a pathway for a late-stage U-enriched pegmatitic fluid. The fluid interacted with the U-free microlite to produce a distinct U enrichment along the fractures and, simultaneously, led to the formation of the U-rich rim. The latter is characterized by a large number of irregular cracks which, as indicated by radiation damage microstructures observed by TEM, are the result of metamictization. Following the stage of U incorporation into microlite, the host rock was subjected to intense argillitic alteration, but there is no evidence of U loss from microlite. It appears, therefore, that microlite is not only able to scavenge U from a fluid at elevated temperatures but also to retain the element during low-temperature alteration. Viewed from a different perspective, these results help in assessing the long-term performance of pyrochlore-based nuclear waste forms. The latter are currently under development for the immobilization of excess weapons plutonium. Our investigation emphasizes the importance of natural analogues for evaluating the durability of waste form materials over geologic time spans.

These integrated multidisciplinary approaches and tools are used to identify the key environmental functions and structures (physical and hydrobiogeochemical) at the wetlands, watershed, and ground-water basin scale that can be applied in ecosystem characterization and socioeconomic analysis. The main goal is to develop an integrative approach and model of the interactions of climate, geology, hydrology, terrestrial and aquatic biota, and socioeconomic activity that can be used as a management tool to make informed decisions about population growth, water use and land development within a hydrological system. The approach draws upon established methods, such as the ASTM Expedited Site Characterization (ESC) and the ASTM Conceptualization and Characterization of Ground-Water Systems (C&C), and established modeling codes, such as HSPF and MODFLOW. The benefits from this type of approach are: 1) improved understanding of the interactions among hydrologic, wetland and stream systems, and socioeconomic activities in watersheds or ground-water basins; 2) development of a unique GIS-based approach and tools for watersheds or ground-water basins undergoing urbanization that is rapid, cost-effective, and scientifically valid, and quantifies dynamic relationships among land use, hydrology, and wetland and stream ecosystems; 3) estimation of the opportunity costs of alternative hydrologic system policies in the affected human communities; and 4) development of Decision Support Systems, through local community input and involvement, to effectively integrate the use of the GIS-based approach and tools into the environmental planning and decision-making process for long-term watershed, ground-water basin, or wetlands management.

There are two uncertainties associated with them: 1) surface processes that control the overall growth rate; 2) dependence of growth mechanism upon supersaturation. We compare experimental evidence with fundamental growth theories to show where popular affinity-based rate expressions hold or break down. Using in situ Atomic Force Microscopy (AFM), we conducted calcite growth experiments to determine (1) the supersaturation (s) range where growth occurs only by spiral formation; (2) the critical supersaturation that initiates a surface nucleation mechanism; (3) step velocities, Vs, and the slopes of growth hillocks, p; (4) normal growth rates, Rm, for single spirals; and (5) dependence of Rm upon dislocation source structure. We find that, at lower values of s (0 to 0.8), growth is initiated solely by surface imperfections including screw dislocations. Thus, crystal defect-originated growth, in particular, spiral growth, is the manifested mechanism. When s >0.8, 2-D nucleation becomes increasingly important. Measurements of Rm for {104} faces grown by single spirals indicate a superlinear dependence of Rm upon chemical affinity. AFM observations demonstrate that growth kinetics is controlled by dislocation source structures in addition to supersaturation and the dominant growth mode is hillock formation initiated at complex dislocation sources. General surface process-based rate expressions were derived by analyzing the dependence of p upon dislocation source structures to reveal a complex relationship between Rm and chemical affinity. These expressions can be approximated by second order affinity-based rate laws only under special conditions: (1) growth proceeds only by the development of single-sourced, single spirals and (2) growth occurs at the very near-equilibrium conditions where spiral formation is the only operative mechanism. This suggests that chemical affinity-based rate laws obtained by measuring temporal changes in solution chemistry yield composite rates from different dislocation sources and do not generally give meaningful interpretations of growth mechanism.

Phreatophytes such as poplars transpire VOCs through their leaves during the growing season, metabolize VOCs in the rhizosphere through the biotic activity of fungi and bacteria growing symbiotically along the roots, and depress water levels in an aquifer by removal of groundwater through transpiration. One technique is the use of engineered systems of hybrid poplars with roots directed to relatively deep aquifers. In 1999, approximately 500 such poplars were planted in a groundwater remediation project at Argonne National Laboratory, near Chicago. Trees were planted in large-diameter boreholes drilled through approximately 30 ft of glacial tills and perched saturated zones to a contaminated sand and gravel unit. The boreholes were lined with plastic and filled with mixtures of topsoil, manure, and sand to constrain the developing roots downward. Groundwater modeling was performed to evaluate the anticipated effects of the trees on the groundwater flow system. Initially the modeling determined best estimates of input parameters and boundary conditions to provide a suitable match to pre-remedial conditions in steady-state and transient cases. Then the future effects of mature, deep-rooted hybrid poplars on the flow system were modeled, including transient seasonal effects. The modeling suggests that the mature trees will provide containment of groundwater from the upgradient source areas even during the trees' dormant winter periods, and groundwater will have a residence time of 5 to 17 months in the microbially active rhizosphere of the poplars. The results also suggest, however, that during the dry season, the water demand of the trees, combined with the decreased flux of water into the aquifer, may dewater portions of the aquifer and therefore stress portions of the plantation.

The nitrogen isotope value reflects nitrogen fixation by type II methanotrophs. The delta (super 13) C value of 18 carbon fatty acids, diagnostic of type II methanotrophs, closely matched the delta (super 13) C value of organic carbon. The carbon and nitrogen isotopic evidence indicates that approximately 78% of the organic matter in this soil was derived from type II methanotrophs, which were also responsible for the consumption of methane and production of nitrous oxide.

Complex proteins and their amino acid residues are believed to play determinate roles in biomineralization phenomena but their effects on kinetics, thermodynamics, and growth morphology are not understood. Advances in our ability to unravel biologically-induced mineralization by microscopic in situ observation have rejuvenated interests in understanding how microbes and higher organisms synthesize minerals at very near-equilibrium conditions.This study quantifies the effect of amino acids and related organic compounds on step migration rates for the (104) calcite surface using in situ Fluid Cell AFM. L-aspartic and L-glutamic acids are abundant in natural biomineralizing systems while maleic, malonic, and L-alpha-aminobutyric acids were selected to probe mechanisms by which individual functional groups modify growth. Experiments were conducted using control and 0.01 molal organic-doped solutions, at pH = 8.5, IS = 0.1, and supersaturations = 0.6-1.2. Calcium and carbonate activity ratios were adjusted to approximately 1.0 for each solution. Measurements of step velocities show that glutamic acid acts as an overall inhibitor to single spiral growth. In contrast, L-alpha-aminobutyric acid, which lacks a carboxylic functional group, increased step velocities. All of the compounds affected growth morphology by changing and rounding the dominant step edge directions except L-alpha-aminobutyric acid. The extents of the rate enhancing/inhibiting effects were dependent upon supersaturation. These findings indicate the site-specific interactions of carboxyl and amine groups with the four types of kink sites found at calcite step edges. Our analysis suggests that unique growth geometries result from perturbations in microscopic kinetics and possibly thermodynamics.

We have developed new methods for the sampling and isotopic analysis of CAHs in air and water and applied these to measure isotopic fractionation of C and Cl during vapor-liquid partitioning and microbial degradation in liquid cultures in the laboratory. We have also performed several field studies of C and Cl isotopes in contaminated aquifers in which either natural or engineered degradation of CAHs has occurred. Two field sites, both contaminated with trichloroethene (TCE) but undergoing different remediation regimes are shown here to demonstrate the application of C and Cl isotopes in field investigations. Multiple sampling events over the course of one year at a former manufacturing facility followed isotopic changes as the site underwent extensive remediation including steam injection, extraction and sub-surface heating. Complex plume composition with multiple organic carbon sources (TCE, hydraulic fluid, paint-shop solvents, petroleum products, and sewage) complicated the interpretation of any site-wide trends. C and Cl isotope ratios indicated processes (evaporation, degradation, and dissolution) consistent with known well histories (proximity to organics, steam injection, heating, etc). In some wells the observed 13-C and 37-Cl enrichments, more than +3 per mil relative to the pure phase DNAPL source, were indicative of significant TCE degradation with time. In contrast, at a manufacturing facility where no engineered remediation has been started, evidence for biodegradation and multiple TCE sources was identified. TCE was the predominant source of both organic carbon and chlorine within the plume. The enrichments of both 13-C and 37-Cl within one arm of the plume indicate biodegradation, while other wells indicate that evaporation is the predominant mechanism of natural attenuation, with 37-Cl enrichments up to +4 per mil relative to source wells.

Elevated arsenic concentrations occur in Hot Creek as a result of geothermal inputs; arsenic is introduced primarily as As(III) but is rapidly oxidized to As(V). Microbial processes were found to contribute significantly to the observed As(III) oxidation and pure cultures of arsenite-oxidizing bacteria have been isolated from Hot Creek. Total arsenic behaves conservatively in Hot Creek and is diluted by flow from the Owens River, a tributary of Lake Crowley. Redox cycling of arsenic in Lake Crowley is strongly influenced by seasonal patterns of stratification and aperiodic withdrawals of deep water; Lake Crowley is a reservoir in the Los Angeles Aqueduct system. In contrast to other freshwater systems studied previously and perhaps because of the large inputs of phosphorus (also of geothermal origin) to Lake Crowley, uptake and transformation of arsenic by phytoplankton do not appear to be important processes in the arsenic cycle in this system.

With the notable exception of the identification of three evolutionary faunas by Sepkoski, nearly all attempts to describe this hierarchy have been qualitative, focusing on the perceived relationships among different ecological or taxonomic entities. In recent years, however, new techniques have been developed that should allow the quantitative identification and characterization of units with discrete time and space boundaries. Previous lacunarity analyses of generic level biodiversity time series compiled by Sepkoski suggested that they are consistent with multiple scale, hierarchical, and multiplicative processes. We have further analyzed these sequences using wavelet analysis. Wavelets decompose a time series into scaled components, whose fit to a local region of the series is determined. Wavelet analysis, unlike more traditional methods of time series analysis, can thus detect multiscaled discontinuities and local features within a series. We extracted and analyzed the component hierarchy in diversity, origination and extinction time series using discrete wavelet transforms. Several different wavelet models were used, including Haar, Morlet, Daubechies, Symlets, Meyer, and biorthogonal. Both normal discrete and discrete packet strategies were followed, progressing from one through six levels. The most useful results were obtained from a biorthogonal wavelet at three and four levels of detail. The magnitude of the components at different scales further supports the existence of a quantifiable superimposed hierarchy in the fossil record.

Attenuated total reflectance Fourier transform infrared (ATR-IR) spectroscopy can quantitatively measure, in situ, both acid hydrolytic and oxidative degradation of TPB as controlled by the exchange cation identity and the structural octahedral Fe content of the clay mineral. Oxidation of TPB at smectite surfaces is directly attributable to octahedral Fe(III) in the clay structure. The concomitant reduction of Fe(III) during TPB oxidation can be analytically measured by X-ray absorption near edge structure (XANES) spectroscopy. The resultant distortion of the clay mineral structure during the reduction of structural Fe could be probed directly by extended X-ray absorption fine structure (EXAFS) spectroscopy. The lack of evidence for clay mineral dissolution during the reaction with TPB permits defining the clay as a catalyst. The combination of these three in situ spectroscopic techniques to measure the reaction in real time, provides powerful insight into the reactivity of clay mineral surfaces.

Large, euhedral zircons from a phlogopite vein in a refractory harzburgite xenolith from the Labait tuff cone, Tanzania, are late Pleistocene in age (400+ or -200 Ka) and crystallized from East African rift-related magmas that infiltrated ancient, cratonic lithosphere. In the Highwood Mountains, Montana, zircons in two glimmerite veins cutting a harzburgite xenolith show a more complicated history, with concordant U-Pb ages ranging from 1.7 to 1.9 Ga. Xenocrystic plagioclase in one of these veins points to an inherited component derived from the crust. Granitic melt inclusions in zircons from this same vein, coupled with a relatively narrow range of Th/U ratios in the older zircons like-wise suggest an inherited (crustal) zircon population. The crystallization of this vein is best dated from analyses of a zircon rim that incorporated a phlogopite crystal, yielding an age of 1817+ or -32 Ma, similar to previous U-Pb determinations of the age of monazite from the same vein (1779+ or -2 Ma, Carlson and Irving, 1994). A second harzburgite xenolith contains zircons with a crystallization age of 1784+ or -20 Ma. Together these results suggest the metasomatism occurred at ca. 1800 Ma, coincident with the formation of the Great Falls tectonic zone. The xeno-crystic plagioclase and zircons, low epsilon (sub Nd) and high (super 87) Sr/ (super 86) Sr at 1.8 Ga, coupled with the crust-like REE patterns of these xenoliths suggest the melt responsible for this metasomatism was derived from older continental crust.

The role these federal facilities played in possibly contaminating water bodies should not be minimized unduly, nor should their role in remediation and long-term management of residual contamination. Ignoring other sources of water-body degradation, however, can result in short-sighted and single-focused remediation responses that, by their nature, will probably be ineffective. The task of remediating and managing water bodies requires broad-based assessments of the full nature and extent of the degradation, the contributors to it, and the preferred short- and long-term remedies. That task is complicated enough but becomes more complex when agencies from several states as well as federal agencies exert jurisdictional control over the water body. Although this article focuses on the Columbia River Basin, the concepts presented could apply to other water bodies shared by several states and degraded by multiple users. What is needed to restore and manage these degraded water bodies is a compact - a legislatively created, institutionalized relationship of the entities with interests in the protection and sustainable development of the water body.

Success of genome-based biology will, to a large extent, depend on the development of new approaches and tools for efficient comparative analysis of the genomes and their organization. We have developed a technique for detecting possible functional coupling between genes based on detection of potential operons. The approach involves computation of "pairs of close bidirectional best hits", which are pairs of genes that apparently occur within operons in multiple genomes. Using these pairs, one can compose evidence (based on the number of distinct genomes and the phylogenetic distance between the orthologous pairs) that a pair of genes is potentially functionally coupled. The technique has revealed a surprisingly rich and apparently accurate set of functionally coupled genes. The approach depends on the use of a relatively large number of genomes, and the amount of detected coupling grows dramatically as the number of genomes increases.

One result of this event was a spectacular eddy feature, thought to represent high concentrations of suspended sediment, that was observed off the eastern shore of the lake north of South Haven, Michigan, on March 12. Remnants of this feature could be detected with visible imagery across the lake weeks later. We have used AVHRR visible, near-infrared, and thermal data, as well as SeaWiFS visible data, to examine temporal changes in southern Lake Michigan associated with the spring sediment resuspension event. We attempted to track the movement and evolution of the disturbance fields by calculating both temporal and spectral changes in successive registered images of the lake. The results suggest that the SeaWiFS images might be useful for qualitative estimation of temporal changes in the particle size distribution of the suspended material. JF - IAGLR '99.

No previous observations have been made in the western areas of the lake adjacent to the Wisconsin bluffs, primarily because these waters were considered to be non-depositional and thus limited in the amount of resuspendable sediment available for transport. During 1998, the first EEGLE field year, we used an instrumented tripod to make measurements intended to test the hypothesis that the recurrent winter-spring resuspension event (misnamed "plume") includes new material eroded from the Wisconsin near-shore. The results show that the local sediment, a sandy cohesive clay, is indeed resuspended in response to the combined action of currents and surface waves. Net horizontal sediment flux in April was almost directly parallel to the shore and toward the south. In November, however, the net horizontal sediment flux was onshore, perhaps representing the temporary storage of a more easily resuspendable pool of sediment. JF - IAGLR '99.

The isotopic fractionation of carbon and chlorine was determined during aerobic degradation of dichloromethane by MC8b, a gram-negative methylotrophic bacterium. Estimated values of isotopic fractionation were 0.9576 plus or minus 0.0015 for carbon and 0.9962 plus or minus 0.0003 for chlorine. The carbon isotope effect was about twice that resulting from the microbial oxidation of methane. Similar studies conducted for a variety of chlorinated aliphatic hydrocarbons (CAH) would contribute towards the characterization and remediation of CAH-contaminated sites.

The radiation tolerance of C. heintzii, based on super(60)Co gamma irradiation experiments, was 165 plus or minus 30 Gy. No bacteria survived irradiation doses greater than 500 Gy. In the presence of plutonium, where alpha particle decay was the primary source of ionizing radiation, the observed toxicity was predominantly radiolytic rather than chemical. This was evident by the greater effect of activity, rather than concentration, on the toxicity noted. Bioassociation of plutonium with C. heintzii was postulated to be an important and necessary step in the observed loss of cell viability since this was the best way to account for the observed death rate. The radiotoxicity of plutonium towards bacteria is a potentially important consideration in the bioremediation of sites contaminated with radionuclide-organic mixtures and the bioprocessing of nuclear waste.

The WTE industry and the municipalities utilizing WTE technologies initially feared that if significant amounts of their ash tested hazardous, the costs and liabilities associated with RCRA Subtitle C hazardous waste management requirements would pose a serious threat to the continued viability of the WTE concept. In this article, the author presents a review of the WTE industry in the five years following the decision, and finds that the specter of the decline of WTE has not materialized.

The process of shaping the Department of Defense Explosives Safety Board (DDESB) standards and the DOD's Final Munitions Rule Implementation Policy serves as a case study for the benefits of mutual openness, knowledge, and trust among regulators, the regulated community, and other interested parties. For DOD, this approach also reflects a continuing trend away from the old culture of closed doors and sovereign immunity carve-outs to a new era of open dialogue and improved environmental stewardship.

Storm total rain accumulations from 43 rain events from 10 radar sites were analyzed. These rain events were stratified into two precipitation types: 1) high-reflectivity horizontal gradient storms and 2) low-reflectivity horizontal gradient events. Overall, the radar slightly overestimated rainfall accumulations for high-reflectivity gradient cases and significantly underestimated accumulations for low-reflectivity gradient cases. Varying degrees of range effects were observed for these two types of precipitation. For high-reflectivity gradient cases, the radar underestimated rainfall at the nearest ranges, overestimated at the middle ranges, and had fairly close agreements at the farthest ranges. A much stronger range bias was evident for low-reflectivity gradient cases. The radar underestimated rainfall by at least a factor of 2 in the nearest and farthest ranges, and to a somewhat lesser extent at midranges.

Effective design and implementation of such a system may, however, prove difficult under conditions of large or unpredictable variations in contaminant migration or ground water flow. Numerical modeling of two-dimensional ground water flow has been used to predict the hydraulic performance of passive, straight, or winged funnel and gate configurations over a range of hydrogeologic and ambient ground water flow conditions. The results of these analyses were used to construct generic correlation diagrams relating upstream capture zone or gate throughput to the barrier, gate, and aquifer characteristics. These diagrams serve as useful screening tools to (1) quantitatively estimate the capture zone of predetermined funnel and gate configurations, or (2) develop preliminary funnel and gate designs that will yield a desired capture zone, independent of aquifer characteristics.

This intermediate cement, with a composition based on that of common glasses, has been designed and tested. The cement formulations included mixed INEEL wastes, blast furnace slag, reactive silica, and INEEL soil or vermiculite, which were activated with potassium or sodium hydroxide. Following autoclave processing, the cements were characterized. X-ray diffraction analysis revealed three notable crystalline phases: quartz, calcite, and fluorite. Results of compressive strength testing ranged from 1452 to 4163 psi, exceeding the U.S. Nuclear Regulatory Commission (NRC)-suggested standard of >500 psi. From American National Standards Institute/American Nuclear Society 16.1-1986 leach testing, effective diffusivities for Cs were determined to be on the order of 10 super(-11) to 10 super(-10) cm super(2)/s and for Sr were 10 super(-12) cm super(2)/s, which are four orders of magnitude less than diffusivities in some other radwaste materials. Average leach indices (LI) were 9.6 and 11.9 for Cs and Sr, respectively, meeting the NRC standard of LI > 6. The 28-day Materials Characterization Center-1 leach testing resulted in normalized elemental mass losses between 0.63 and 28 g/(m super(2) times day) for Cs and between 0.34 and 0.70 g/(m super(2) times day) for Sr. Strontium mass losses meet the <1 g/(m super(2) times day) industry-accepted standard while Cs losses indicate a process sensitive parameter.

The methodology can be used to analyze trade-offs between technical, economic, and environmental concerns. A case study in support of an international lending decision is used to analyze eleven power-sector expansion scenarios in terms of total system cost and environmental residuals. The scenarios are then compared by using a decision analysis tool. A brief comparison of interval and traditional decision analysis methodologies is also provided.

The effect of climatological variability was reduced by averaging the regional unitless scaled PWC (thereafter termed CONCDEP). The sulphur dioxide emissions data from the U.S.A., Canada and northern Mexico were weighted appropriately for each region to produce regional scaled trends of emissions. A regional transport model was used to estimate emission-weighted factors. Generally, the sulphate CONCDEP regional trends were similar to the regional weighted sulphur dioxide emissions. In eastern regions, patterns showed an initial decrease, trendless middle period and final decrease; the latter mandated by new emissions legislative policy. A significant linear regression was obtained for sulphate CONCDEP against regional weighted sulphur dioxide emissions in all regions. Results showed slopes of sulphate CONCDEP and sulphur dioxide emissions in all regions were not significantly different from unity over the monitoring period.

AN - 69102891; 9860982 AB - To identify genes involved in macrophage development, we used the differential display technique and compared the gene expression profiles for human myeloid HL-60 leukemia cell lines susceptible and resistant to macrophage maturation. We identified a gene coding for a protein kinase, protein kinase X (PRKX), which was expressed in the maturation-susceptible, but not in the resistant, cell line. The expression of the PRKX gene was found to be induced during monocyte, macrophage, and granulocyte maturation of HL-60 cells. We also studied the expression of the PRKX gene in 12 different human tissues and transformed cell lines and found that, among these tissues and cell types, the PRKX gene is expressed only in blood. Among the blood cell lineages, the PRKX gene is specifically expressed in macrophages and granulocytes. Antisense inhibition of PRKX expression blocked terminal development in both the leukemic HL-60 cells and normal peripheral blood monocytes, implying that PRKX is a key mediator of macrophage and granulocyte maturation. Using the HL-60 cell variant deficient in protein kinase C-beta (PKC-beta) and several stable PKC-beta transfectants, we found that PRKX gene expression is under control of PKC-beta; hence PRKX is likely to act downstream of this PKC isozyme in the same signal transduction pathway leading to macrophage maturation.

The ability to bind riboflavin distinguishes this flavodoxin from other short-chain flavodoxins which require the phosphate of FMN for flavin binding. The redox potential of the semiquinone/hydroquinone couple of the bound riboflavin is 180 mV less negative than the corresponding complex with FMN. To elucidate the binding of riboflavin, the complex has been crystallized and the crystal structure solved by molecular replacement using native flavodoxin as a search model to a resolution of 0.183 nm. Compared to the FMN complex, the hydrogen-bonding network at the isoalloxazine sub-site of the riboflavin complex is severely disrupted by movement of the loop residues Ser58-Ile64 (60-loop) which contact the isoalloxazine by over 0.35 nm, and by a small displacement of the isoalloxazine moiety. The 60-loop movement away from the flavin increases the solvent exposure of the flavin-binding site. The conformation of the site at which 5'-phosphate of FMN normally binds is similar in the two complexes, but in the riboflavin complex a sulphate or phosphate ion from the crystallization buffer occupies the space. This causes small structural perturbations in the phosphate-binding site. The flexibility of the 60-loop in D. vulgaris flavodoxin appears to be a contributing factor to the binding of riboflavin by the apoprotein, and a feature that distinguishes the protein from other `short chain' flavodoxins. In the absence of the terminal phosphate group, free movement at the 5'-OH group of the ribityl chain can occur. Thus, the 5'-phosphate of FMN secures the cofactor at the binding site and positions it optimally. The structural changes which occur in the 60-loop in the riboflavin complex probably account for most of the positive shift that is observed in the midpoint potential of the semiquinone/hydroquinone couple of the riboflavin complex compared to that of the FMN complex.

It is estimated that biofuel use amounts to about 22,000 PJ (1 PJ = 10 super(15) J), almost 24% of the total energy use in Asia. China and India are the two largest consumers. A relation is developed between the GDP of Asian countries and the percent contribution of biofuels to total primary energy supply. The biofuel energy estimates are used to calculate atmospheric emissions of SO sub(2) and NO sub(k). It is estimated that SO sub(2) emissions from biofuel combustion amount to 1.65 Tg (1 Tg = 10 sub(12) g), about 4.9% of total emissions. The emissions of NO sub(x) are estimated to be 1.47 Tg or 7.7% of the total. These energy and emission estimates are designed to be used in the RAINS-Asia computer model, a comprehensive analytical tool used to study energy use in Asia, its effects on the atmospheric environment, and its subsequent damage to ecosystems.

A generalised temperature and salinity map of the Recent, with related effects like upwelling, sea ice, and surface runoff, has been compiled in a new attempt to define marine climates. Present-day climate-sensitive sediments are included to test their reliability as water mass indicators in the geological past. Then, reversing the approach, water mass maps for the nine Permian stages have been reconstructed from the sediment types as well as from biogeographic considerations. It is clear from the Present-day water mass map that geographically or bathymetrically restricted seaways are more likely to reflect local climate and be distinct from open ocean water masses in salinity or temperature. Our Permian maps have been prepared with this duality in mind: epeiric seaways are portrayed with the most differentiated water masses, while narrow continental shelves are generally similar to adjacent oceanic areas.

The EBR-II PRA explicitly accounts for the role of reactivity feedbacks in reducing fuel damage. The results show that the expected core damage frequency from internal initiating events at EBR-II is very low, 1.6 x 10 super(-6) yr super(-1), even with a wide definition of core damage (essentially that of exceeding Technical Specification limits). The annual frequency of damage, primarily caused by liquid metal fires, from externally initiated events (excluding earthquakes) is 3.6 x 10 super(-6) yr super(-1) and the contribution of seismic events is 1.7 x 10 super(-5) yr super(-1). Overall these results are considerably better than results for other research reactors and the nuclear industry in general and stem from three main sources: low likelihood of loss of coolant caused by low system pressure and top entry double vessels; low likelihood of loss of decay heat removal caused by reliance on passive means; and low likelihood of power/flow mismatch caused by both passive feedbacks and reliability of rod scram capability.

It is difficult to determine the effectiveness of natural CAH attenuation from chemical analyses of groundwater samples because mixing, dispersion, and secondary reactions can mask the chemical evidence of attenuation. In this paper, we explore the application of stable chlorine isotope ratio measurements as a new tool for for evaluating natural attenuation of CAHs. We report stable isotope ratios of chlorine in both trichloroethene (TCE) and inorganic chloride in groundwater from an aerobic aquifer beneath an extensively contaminated industrial site, the Paducah Gaseous Diffusion Plant in western Kentucky. Variations in the concentrations and chlorine isotope ratios of TCE and chloride in the groundwater are consistent with those expected from natural attenuation. These data support a model in which partial TCE degradation occurred in relatively impermeable, clay-rich sediments above the aquifer, and little or no further degradation of TCE occurred within the aquifer. A record of changing conditions within the TCE source area can be inferred from the spatial variation of chlorine isotope ratios for TCE and chloride within the plume.

AN - 70060618; 9820974 AB - Interspecies differences in the liver response to Wy-14,643, a potent peroxisome proliferator in rats and mice, have been demonstrated. While both rats and mice show dramatic increases in the number of peroxisomes, the activity of peroxisomal enzymes involved in the beta-oxidation of fatty acids, and heptocyte replication, Syrian hamsters have a more moderate peroxisome proliferation response and no sustained increase in cell replication. Rats and mice, but not hamsters, develop hepatocellular carcinoma after prolonged exposure to Wy-14,643. To further characterize this species difference, two-dimensional gel electrophoresis (2-DE) has been used to compare the effect of 14-day exposure to various dietary concentrations of Wy-14,643 on liver protein expression in male mice and hamsters. Digitized images of the 2-DE protein maps were searched for significant changes. The peroxisome bifunctional enzyme (PBE) enoyl CoA hydratase/3-hydroxyacyl dehydrogenase, which migrates to the same position in mouse and hamster liver protein 2-DE patterns, increased in abundance by more than three times the control level in both mice and hamsters. In addition to the quantitative change in PBE, significant quantitative changes (P < 0.001) were found in 49 mouse liver proteins (47 decreasing and 2 increasing) and in 35 hamster liver proteins (27 decreasing and 8 increasing). There was little overlap in the mouse and hamster proteins showing quantitative changes in response to Wy-14,643, with the exception of PBE and one unidentified liver protein with an approximate molecular weight of 50,000. These results show that although peroxisome proliferation occurs in the livers of both mice and hamsters exposed to Wy-14,643, other species-specific changes in proteins occur that are independent of the peroxisome proliferation response and that could be related to species-specific susceptibility or resistance to liver tumor induction.

Soils collected offsite in Idaho, Montana, and Wyoming were collected to further characterize NTS fallout in the region. In addition, measurements of super(237)Np and super(137)Cs were used to further identify the source of the Pu from airborne emissions at the Idaho Chemical Processing Plant (ICPP) or fugitive releases from the Subsurface Disposal Area (SDA) in the Radioactive Waste Management Complex (RWMC). It is estimated that the non-fallout Pu in INEEL soils is approximately 5.7 GBq ( similar to 150 mCi) and that the majority of this site-derived Pu has its origin from releases of Pu at the SDA in the early and late 1960s. Stratospheric fallout on the INEEL is approximately one-half of that measured elsewhere in the 40-50 N latitude band such that the 5.7 GBq of Pu originating from the SDA represents an approximate 14 percent increase over that expected from stratospheric fallout. There is convincing evidence from this study that super(241)Am, in excess of that expected from weapons-grade Pu, constituted a part of the buried waste at the SDA that has subsequently been released to the environment. Measurements of super(236)U in waters from the Snake River Plain aquifer and a soil core near the ICPP suggest that this radionuclide may be a unique interrogator of airborne releases from the ICPP. Neptunium-237 and super(238)Pu activities in INEEL soils suggest that airborne releases of Pu from the ICPP, over its operating history, may have recently been overestimated. Future super(236)U measurements in INEEL soils would provide data on the geographical influence of ICPP emissions as well as confirmatory information concerning past releases of Pu from this facility.

The study domain is 20 degree S-50 degree N, 39 degree -154 degree E. Monthly averaged 1 degree x 1 degree dry deposition velocities are estimated for four seasons. Model results show that the dry deposition velocity of SO sub(2) demonstrates strong seasonal and diurnal variability in summer, fall, and spring. In summer, the daytime velocity (in centimeters per second) for SO sub(2) forests is 0.4, over cultivation is 0.2, grassland is 0.5, and ocean is 0.8. Nighttime values of SO sub(2) are two or three times less than daytime values. In winter, the deposition velocity of SO sub(2) does not show much diurnal variability - the value is 0.1-0.2 except over ocean, when it is 0.5. Contrary to SO sub(2), the dry deposition velocity of sulfate only slightly varies with seasons and time of the day. Generally, its value is less than 0.1.

AN - 73892788; 9739086 AB - BACKGROUNDThe self-assembly properties of beta domains are important features of diverse classes of proteins that include cell-adhesion molecules, surface receptors and the immunoglobulin superfamily. Immunoglobulin light-chain variable domains are well suited to the study of structural factors that determine dimerization, including how residues at the interface influence the preferred dimer arrangement.RESULTSSingle-site mutants of light-chain variable domain Len, designated LenQ38E and LenK30T, formed 'flipped' dimers in which one domain was rotated by about 180 degrees compared with the native protein. The dimer in the native protein is similar to that found between variable domains in Fab immunoglobulin fragments. When compared to the native dimer, more surface area is buried, and more hydrogen bonds and salt bridges are formed between the monomers in the flipped conformation.CONCLUSIONSImmunoglobulin light-chain variable domains can form a minimum of two distinct quaternary structures. Single-site mutations resulting from changes of one base, such as the exchange of Gln38 to Glu or Lys30 to Thr, change the 'conventional' dimer of protein Len to a flipped arrangement. Native Len is not found in the flipped-domain dimer conformation because it would have excess positive electrostatic potential at the dimer interface that is not compensated by other forces. Excess negative or positive electrostatic potential at the dimer interface can have a determining effect on the mode of dimerization.

The delta D and delta (super 18) O values of the groundwaters were identical before and after the earthquake. Apparent groundwater ages calculated by tritium- (super 3) He concentrations also did not change, if we correct the addition of radiogenic helium into the samples by the earthquake. These observations may be attributed to following phenomenon; (1) release of radiogenic He as a result of micro-fracturing of rocks during the earthquake followed by degassing from the aquifer system, in the amount of about 4.0+ or -1.3X10 (super -9) cm (super 3) STP/cm (super 3) -rock, (2) simple mixing of low-tritium water with high radiogenic helium in the clay layer and high-tritium water with atmospheric helium in the aquifer, and (3) flow path mixing in the region of the sample screen. If we take the (1) degassing hypothesis as a function of micro-fracturing, it is possible to calculate the total He degassing related to the Kobe earthquake, 4X10 (super 11) cm (super 3) STP, which is about 3% of the steady-state global He flux of 1.2X10 (super 13) cm (super 3) STP/year. Thus, earthquake may play an important role in He degassing from the solid earth.

The results indicated that the Desulfovibrio spp. used all of the explosive compounds studied as their sole source of nitrogen for growth. The concentrations of TNB, RDX, and HMX in the culture media dropped to below the detection limit (<0.5 ppm) within 18 days of incubation. We also observed the production of ammonia from the nitro groups of the explosive compounds in the culture media. This ammonia served as a nitrogen source for the bacterial growth, and the concentration of ammonia later dropped to <0.5 mg/L. The sulfate-reducing bacteria may be useful in the anaerobic treatment of explosives-contaminated soil.

These experiments were performed to identify K-ras mutations in tissues from control and radiation-exposed mice. By modifying the technique of the 'enriched' polymerase chain reaction (PCR), it was possible to detect point mutations at codon 12 of the K-ras oncogene from 25-year-old paraffin-embedded normal lungs and lung adenocarcinomas from mice exposed to radiation. Together, a total of 120 lung tissues were screened for point mutations at codon 12 of the K-ras oncogene in this study. A significant increase in K-ras codon 12 point mutations was observed in the normal lungs from mice exposed to 24 once-weekly neutron irradiations (100%), compared with normal lungs from mice with sham-irradiation (50%) (p0.05). The validity of the technique was confirmed by sequencing two of the mutants. In doing so, a K-ras 13(Asp) point mutation was observed. The data suggest that high-linear energy transfer (LET) neutron radiation was more effective than low-LET gamma -rays in inducing K-ras point mutations at codon 12 in the lungs of B6CF sub(1) mice.

We used data from a chronosequence of tallgrass prairie restorations and a path analysis approach to evaluate how the lengths of two dia size classes of fibrous roots, the length of external mycorrhizal hyphae, microbial biomass C, hot-water soluble carbohydrate C and soil organic C interact to promote the stabilization of soil aggregates. The measured binding agents accounted for 88% of the variation in macroaggregates >212 mu m diameter and goodness-of-fit indexes indicated a good practical fit of the path model to the data. The restoration of macroaggregate structure in this system was apparently driven by the direct and indirect effects of roots and external hyphae, with lesser relative contributions by the three measured C pools. Although the two root size classes had similar direct effects on the percentage of macroaggregates, their indirect contributions differed substantially. Fine roots (0.2-1 mm diameter) exerted considerable indirect effects via their strong influences on external hyphae and microbial biomass C. Very fine roots (<0.2 mm dia) made a stronger contribution to soil organic C than fine roots, but their overall indirect contribution to aggregation was minimal. In addition, the relative importance of each binding agent varied for different size fractions of macroaggregates and generally supported the hypothesis that the effectiveness of various binding mechanisms depends on the physical dimensions of the binding agents relative to the spatial scales of the aggregate planes of weakness being bridged.

A mixture of nonmethane hydrocarbons (NMHCs) and oxygenated hydrocarbons (OxHCs) was emitted from the surface at rates exhibiting large seasonal and year-to-year variations. The average emission rate (and standard error) of the total NMOCs around noontime on sunny days during the growing seasons for the 2-year period was 1,300 plus or minus 170 mu g m super(-2) h super(-1) (mass of the total NMOCs per area of enclosed soil surface per hour) or 5.5 plus or minus 0.9 mu g g super(-1) h super(-1) (mass of the total NMOCs per mass of dry plant biomass in an enclosure per hour), with about 10% and 70% of the emissions being composed of tentatively identified NMHCs and OxHCs, respectively. Methanol was apparently derived from both the soil and vegetation and exhibited an average emission rate of 460 plus or minus 73 mu g m super(-2) h super(-1) (1.4 mu 0.2 mu g g super(-1) h super(-1)), which was the largest emission among the NMOCs. The year-to-year variation in the precipitation pattern greatly affected the NMOC emission rates. Emission rates normalized to biomass density exhibited a linear decrease as the growing season progressed. The emission rates of some NMOCs from vegetation subjected to hypoxia, frost, and physical stresses were significantly greater than the average values observed at the site. Emissions of monoterpenes and cis-3-hexen-1-ol were accelerated during the flowering of the plants and were much greater than those predicted by algorithms that correlated emission rates with temperature.

Metal and EPR analyses confirm that Zn(II) is ligated to a binding site that is distinct from the Fe site. When Zn(II) is bound to this site, electron transfer between the quinones Q sub(A) and Q sub(B) (Q sub(A) super(-)Q sub(B) arrow right Q sub(A)Q sub(B) super(-)) is slowed and the room-temperature kinetics become distributed across the microsecond to millisecond time domain. This effect of metal binding on the kinetics is similar to the more global effect of cooling RCs to 2 degree C in the absence of Zn(II). This suggests that Zn(II) binding alters localized protein motions that are necessary for rapid Q sub(A) super(-)Q sub(B) arrow right Q sub(A)Q sub(B) super(-) electron transfer. Inspection of the RC crystal structure suggests a cluster of histidine ligands located beneath the Q sub(B) binding pocket as a potential binding site.

Strontium isotope ratios ( super(87)Sr/ super(86)Sr) of pore waters from the aquifer, confining units, and the glacial till ranged from 0.7069 to 0.7082. The super(87)Sr/ super(86)Sr ratios in aquifer pore waters decrease with increasing distance from the aquifer recharge area, and this is interpreted to be the result of mixing and water-rock interaction within the aquifer. The solute composition of the recharging groundwater is modified by the local lithology, causing distinct geochemical patterns along different flow paths within the aquifer. Whole-rock super(87)Sr/ super(86)Sr ratios indicate that the shales and till are generally more radiogenic than the aquifer sandstone. The authigenic carbonate cements and rock-forming minerals comprising the major lithologic units had little apparent influence on the pore-water Sr chemistry. Carbonate cement leachates from the till and the aquifer sandstone are more radiogenic than those from the confining shale formations. Feldspar separates from the aquifer sandstone have relatively radiogenic Sr isotope ratios, whereas bentonites from the Milk River and Colorado Shale Formations have whole-rock and leachate Sr isotope ratios that are relatively unradiogenic. Ratios of most Milk River aquifer pore waters are lower than those of any leachates or whole rocks analyzed, except the bentonites. The super(87)Sr/ super(86)Sr ratios of exchangeable Sr in the bentonites are similar to ratios found in the more evolved pore waters. Simple rock-water interaction models calculated for the whole-rock, leachate, and exchangeable-ion/pore-water pairs indicate that ion exchange with bentonite clays within the Milk River and Colorado Shale Formations appears to influence the isotopic evolution of the pore-water Sr in each of these units.

This guidance reflects the fact that at the heart of an environmental impact statement is a comparative analysis of alternatives, including the proposed action; this analysis should address the environmental impacts in proportion to their potential significance, avoid addressing insignificant impacts in detail, and focus analysis resources to be as cost-effective as possible. Accordingly, a probabilistic risk analysis-based methodology to satisfy DOE guidance was developed and implemented for the DOE Waste Management Programmatic Environmental Impact Statement (WM PEIS). The methods are described and illustrated, and an outline of the computational framework is presented. This methodology, although developed for the WM PEIS, is, of course, applicable to general safety analyses. The implementation of the methods for the WM PEIS is summarized, and the extension of the methods to site-specific applications is explained.

AN - 79975881; 9646499 AB - The development of a method for the analysis of organoarsenic compounds that combines dithiol derivatization with solid-phase microextraction (SPME) sample preparation and gas chromatography-mass spectrometry (GC-MS) is described. Optimization focused on a SPME-GC-MS procedure for determination of 2-chlorovinylarsonous acid (CVAA), the primary decomposition product of the chemical warfare agent known as Lewisite. Two other organoarsenic compounds of environmental interest, dimethylarsinic acid and phenylarsonic acid, were also studied. A series of dithiol compounds was examined for derivatization of the arsenicals, and the best results were obtained either with 1,3-propanedithiol or 1,2-ethanedithiol. The derivatization procedure, fiber type, and extraction time were optimized. For CVAA, calibration curves were linear over three orders of magnitude and limits-of-detection were < 6.10(-9) M in solution, the latter a more than 400 x improvement compared to conventional solvent extraction GC-MS methods. A precision of < 10% R.S.D. was typical for the SPME-GC-MS procedure. The method was applied to a series of water samples and soil/sediment extracts, as well as to aged soil samples that had been contaminated with Lewisite. JF - Journal of chromatography.

The signaling role of protein kinase C-beta. AN - 79838280; 9565574 AB - Induction of the 92-kDa gelatinase (MMP-9) gene expression is associated with macrophage differentiation. In this study, we explored the regulatory mechanisms underlying this differentiation-associated MMP-9 gene expression in human HL-60 myeloid leukemia cells and human peripheral blood monocytes. Phorbol 12-myristate 13-acetate (PMA) markedly induced MMP-9 gene expression in HL-60 cells; the induction closely paralleled the timing and extent of PMA-induced cell adhesion and spreading, a hallmark of macrophage differentiation. Similarly, treatment with PMA or macrophage-colony stimulating factor stimulated adherence and spreading of blood monocytes with a concurrent 7- or 5-fold increase in MMP-9 production, respectively. In protein kinase C (PKC)-beta-deficient HL-60 variant cells (HL-525), PMA failed to induce cell adhesion and MMP-9 gene expression. Transfecting HL-525 cells with a PKC-beta expression plasmid restored PKC-beta levels and PMA inducibility of cell adhesion and spreading as well as MMP-9 gene expression. Induction of cell adhesion and MMP-9 gene expression in HL-60 cells and blood monocytes was strongly inhibited by neutralizing monoclonal antibodies to fibronectin (FN) and its receptor alpha5 beta1 integrin. HL-525 cells, which constitutively display high levels of surface alpha5 beta1 integrin, adhered and spread on immobilized FN with concomitant induction of MMP-9 gene expression. Cytochalasins B and D were each a potent inhibitor of MMP-9 production. Our results suggest that alpha5 beta1 integrin-mediated interaction of immature hematopoietic cells with FN plays a critical role in modulating matrix-degrading activities during macrophage differentiation.

AN - 79836628; 9565575 AB - Tumor necrosis factor-alpha (TNF-alpha) gene is one of the early response genes induced by phorbol 12-myristate 13-acetate (PMA) in human HL-60 myeloid leukemia cells. In the present study, we examined the role of the TNF-alpha autocrine loop in PMA-induced macrophage differentiation and gene expression of 92- and 72-kDa gelatinases (MMP-9 and MMP-2). In HL-60 cells, PMA inhibited cell proliferation and induced cell adhesion and spreading, expression of surface maturation marker OKM1 and phagocytic activity, as well as the expression of both gelatinases, which all characterize the macrophage phenotype. In contrast, TNF-alpha alone was only effective in inhibiting cell proliferation. Blocking the endogenous TNF-alpha activity with neutralizing anti-TNF-alpha antibodies abolished all these PMA-induced events with the exception of MMP-2 gene expression. Since fibronectin (FN)-mediated cell adhesion and spreading are prerequisite for both macrophage differentiation and MMP-9 gene expression in HL-60 cells, we hypothesized that TNF-alpha might be involved in modulating the expression of either the FN or its integrin receptor genes. Whereas PMA substantially enhanced the steady state mRNA and protein levels of both FN and alpha5 beta1 integrins, TNF-alpha alone had little effect on the expression of these genes. However, anti-TNF-alpha antibodies blocked PMA-induced augmentation of both alpha5 and beta1 integrin gene expression without affecting the expression of the FN gene. Our results suggest that TNF-alpha may regulate macrophage differentiation and critical matrix-degrading activities of myeloid progenitor cells in an autocrine manner by augmenting surface levels of the alpha5 beta1 integrin, thus promoting interactions with the extracellular matrix, a key event for maturation and migration of these cells during inflammation.

AN - 79901073; 9604187 AB - Zinc protoporphyrin (ZPP) measurement is a required test under the Occupational Safety and Health Administration's lead standard. However, there is no mention of the influence of hemoglobinopathy on the ZPP test value. We undertook a retrospective laboratory review of 382 employees at the Argonne National Laboratory who had been subjects in a lead surveillance program since 1982. A total of 321 samples were analyzed, after female subjects and samples with abnormally high bilirubin levels were excluded. A group with low mean red blood cell volume (MCV; less than 80.0 fL) was compared with a group with normal MCV (greater or equal to 80.0 fL). A statistically significant difference was noted in ZPP (P < 0.007) and total bilirubin (P < 0.0003) values of two groups. There was no statistically significant difference noted in age, lead levels, or iron levels between the two groups. Abnormally high ZPP levels may occur in individuals with hemoglobinopathies. Only a minor part of this elevation could be explained by the higher bilirubin levels.

AN - 79888761; 9591686 AB - The efficiency of triplet energy transfer from the special pair (P) to the carotenoid (C) in photosynthetic reaction centers (RCs) from a large family of mutant strains has been investigated. The mutants carry substitutions at positions L181 and/or M208 near chlorophyll-based cofactors on the inactive and active sides of the complex, respectively. Light-modulated electron paramagnetic resonance at 10 K, where triplet energy transfer is thermally prohibited, reveals that the mutations do not perturb the electronic distribution of P. At temperatures > or = 70 K, we observe reduced signals from the carotenoid in most of the RCs with L181 substitutions. In particular, triplet transfer efficiency is reduced in all RCs in which a lysine at L181 donates a sixth ligand to the monomeric bacteriochlorophyll B(B). Replacement of the native Tyr at M208 on the active side of the complex with several polar residues increased transfer efficiency. The difference in the efficiencies of transfer in the RCs demonstrates the ability of the protein environment to influence the electronic overlap of the chromophores and thus the thermal barrier for triplet energy transfer.

AN - 79867425; 9588360 AB - Mortality data for B6CF1 mice exposed to 60Co gamma rays for the duration of life were used to make quantitative predictions of age-specific mortality observed in comparably exposed beagles. Simple Kaplan-Meier survival curves for the beagles and their 95% confidence intervals were computed for each dose-rate group observed. A dose-response equation was estimated from the mortality data for mice using a proportional hazard model. The dose-response model for mice was then used to generate predicted survivorship curves at dose rates that would recreate the dose burdens observed in the beagle at comparable points within the life span of the two organisms. When these predicted survivorship curves were scaled to adjust for species differences in the life span of control animals, the predictions for the mouse fell within the confidence intervals observed for the beagle. The successful interspecies extrapolation of age-specific mortality risks for species as different as the mouse and dog enhances both the value of studies involving laboratory animals and the potential relevance of the animal studies to the prediction of health effects in humans.

The results confirm significant decreases in fatigue life in water. Unlike the situation with ferritic steels, environmental effects on Types 304 and 316NG stainless steel are more pronounced in low-DO than in high-DO water. Experimental results have been compared with estimates of fatigue life based on a statistical model. The formation and growth of fatigue cracks in air and water environments are discussed.

A fully connected recurrent network is used for process identification, and a multilayer feedforward network is used for process control. The two neural networks are arranged in series for closed-loop control of oxides of nitrogen (NO sub(x)) emissions of a simplified representation of a dynamical system. Plant data from one of Commonwealth Edison's coal-fired power plants are used for testing the approach, with initial results indicating that the method is feasible. However, further work is required to determine whether the method remains feasible as the number of state variables and control variables are increased.

We studied the effect of aquo and complexed/precipitated neptunium on the growth of C. heintzii in noncomplexing glucose and phosphate-buffered nitrilotriacetic acid (NTA) growth media. Equilibrium chemical speciation modeling and absorption spectroscopy were used to link neptunium speciation to biological growth inhibition. Our results show that metal toxicity of aquo NpO sub(2) super(+) significantly limits the growth of C. heintzii at free metal ion concentrations greater than approximately 10 super(-5) M. However, neptunium concentrations greater than or equal to 10 super(-4) M do not cause measurable radiotoxicity effects in C. heintzii when present in the form of a neptunium-NTA complex or colloidal/precipitated neptunium phosphate. The neptunium-NTA complex, which is stable under aerobic conditions, is destabilized by microbial degradation of NTA. When phosphate was present, degradation of NTA led to the precipitation of a neptunium-phosphate phase.

AN - 80030274; 9680192 AB - The formation of the antibody variable domain binding unit (Fv) is the net result of three competing assembly reactions. The affinities of concurrent homologous interactions of heavy and light chain variable domains limits the heterologous interaction leading to productive formation of the Fv. To address the possible role of light chain dimerization in this phenomenon, the Gln38 residue at the dimer interface of an immunoglobulin light chain variable domain (VL) was replaced by charged amino acids. The effects of these mutations on VL homodimer formation were monitored by small-zone size exclusion HPLC and the affinities of interaction were determined by computer simulation. Reduced VL homodimerization was observed in three of the four mutants, Q38R, Q38D and Q38K. The association constants for the Q38R and Q38D homodimers were 1.2 x 10(4) and 3.2 x 10(3) M(-1), respectively. This corresponded to a 20-75-fold reduction in the homodimer association constant relative to the wild-type VL, which had an association constant of 2.4 x 10(5) M(-1). Surprisingly, the fourth charge mutant, Q38E, had a higher association constant than the wild-type VL. The potential for charged residues to facilitate heterodimeric assembly of immunoglobulin domains was also tested. Heterodimerization was observed between the Q38D and Q38R V(L)s, but with an association constant of 4.7 x 10(4) M(-1), approximately fivefold lower than that obtained for homodimerization of the native V(L). In addition, replacement of the neutral, solvent-accessible Gln38 residue with either Asp or Arg was found to be significantly destabilizing. These results suggest that charged residues could be introduced at immunoglobulin domain interfaces to guide heterodimer formation and to minimize unfavorable competing homologous associations. Nonetheless, these apparently simple modifications may also result in unintended consequences that are likely to depend upon structural features of particular variable domains.

Two long-range transport models are used to estimate airborne concentrations and deposition of SO sub(2) and sulfate, based on available data on emissions originating from area and major point sources. Modeling results demonstrate how human health and ecological impacts are related to the projected scenario of industrial growth, in terms of the critical level (or concentration) and critical loads. The current approach provides an effective and valuable tool for preliminary assessment of potential impacts of these changes on human health and critical ecosystems in the region for use in integrated energy and environmental risk assessments.

This detector is designed to operate at varying temperatures which take advantage of the different rates of reaction of the hydrocarbon classes with ozone to yield a measure of their atmospheric reactivity. When operated at high temperatures (170 degree C), all hydrocarbons will give a chemiluminescence signal. Reported here is a direct comparison of the ozone chemiluminescent detector (operated at a temperature of 170 degree C) with a flame ionization detector. This comparison was accomplished by connecting a capillary gas chromatograph to each of the two detectors by means of a switching valve. Twenty-seven compounds representing alkanes, alkenes, aromatics, and oxygenated hydrocarbons (aldehydes, ketones, alcohols, and ethers) were studied. For the compounds studied, analytical sensitivities were 10-1000 times better for the chemiluminescence detector. The results of this comparison indicate that the response of the chemiluminescent detector at 170 degree C correlates with a total carbon detector (flame ionization detection) and that total response is a measure of total carbon in the sample. The chemiluminescent system will be very useful for gas chromatographic detection of atmospheric hydrocarbons, particularly of oxygenates in complex mixtures.

These atmospheric nitrogen species are strongly coupled chemically by a clearly temperature-dependent equilibrium in the troposphere. A chemical method that can measure both nitrogen dioxide and PANs rapidly and with sub-part-per-billion detection is described that is based upon a modified luminol detection system coupled to a capillary gas chromatographic column by using helium as a carrier. The system can readily separate and detect nitrogen dioxide, peroxyacetyl nitrate, peroxyproprionyl nitrate, and peroxybutyrl nitrate with detection limits in the low tens of parts per trillion with total analysis time of less than 1 min. Calibration of PAN by thermal decomposition to nitrogen dioxide is demonstrated with PAN detection sensitivities approximately 75% of the sensitivities observed for NO sub(2) luminol detection by using helium as a carrier gas.

The mutant strain, named AFP111, fermented glucose more slowly than did its wild-type ancestor, strain W1485, and generated a very different spectrum of products. AFP111 produced succinic acid, acetic acid, and ethanol in proportions of approx 2:1:1. Calculations of carbon and electron balances accounted fully for the observed products; 1 mol of glucose was converted to 1 mol of succinic acid and 0.5 mol each of acetic acid and ethanol. The data support the emergence in E.coli of a novel succinic acid:acetic acid:ethanol fermentation pathway.

L-lactic acid is often the desired enantiomer for such applications. However, stereospecific lactobacilli do not metabolize starch efficiently. In this work, Argonne researchers have developed a process to convert starchy feedstocks into L-lactic acid. The processing steps include starch recovery, continuous liquefaction, and simultaneous saccharification and fermentation. Over 100 g/L of lactic acid was produced in less than 48 h. The optical purity of the product was greater than 95%. This process has potential economical advantages over the conventional process.

Mo is particularly interesting since its solar composition involves s-, r- and p-isotopes. The analyses were made by resonant ionization MS and can measure the isotopic composition of trace elements in the ppm range from mu m-sized presolar grains. The Mo s-process signature in separate grains provides a record of s-process nucleosynthesis in individual TP-AGB stars. Linear correlations among the Mo isotopic ratios indicate mixing of s-process material and a component of near-solar composition. If the Mo in the SiC grains is representative of solar system s-process material, the relative contribution of s-process Mo in the solar system is estimated as 41.7 + or - 1.3 % for (super 95) Mo, 55.1 + or - 1.8 % for (super 97) Mo, and 72.6 + or - 1.5 % for (super 98) Mo.

Cleanup of the Weldon Spring site consists of several integrated components. The quarry residuals operable unit (QROU) is one of four operable units being evaluated. In accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended, a remedial investigation/feasibility study (RI/FS) is being conducted to evaluate conditions and potential responses for the following areas and/or media that constitute the QROU: (1) the residual material (soil and sediment) remaining at the Weldon Spring quarry after removal of the bulk waste (about 11 million L (3 million gal) of uranium-contaminated ponded water was also addressed previous to bulk waste removal); (2) other media located in the surrounding vicinity of the quarry, including adjacent soil, surface water, and sediment in Femme Osage Slough and several creeks; and (3) quarry groundwater located primarily north of Femme Osage Slough. Potential impacts to the St. Charles County well field downgradient of the quarry area are also being addressed as part of QROU RI/FS evaluations. For remedial action sites, it is DOE policy to integrate values associated with the National Environmental Policy Act (NEPA) into the CERCLA decision-making process. The analyses contained herein address NEPA values as appropriate to the actions being considered for the QROU. A work plan summarizing initial site conditions and providing conceptual site hydrogeological and exposure models was published in January 1994. The RI and baseline risk assessment (BRA) reports have been completed. The RI discusses in detail the nature and extent and the fate and transport of contamination at the quarry area.

We have constructed site-specific mutants that eliminate the sequence differences at these positions (L212Glu-L213Asp1Ala-Ala or M246Ala-M247Ala1Glu-Asp), and have reversed that asymmetry by constructing a quadruple-mutant strain, 'RQ' (L212Glu-L213Asp-M246Ala-M247Ala1Ala-Ala-Gl u-Asp). The mutations were designed to change the charge distribution in the quinone-binding region of the reaction center; none of the strains is capable of photosynthetic growth. In photocompetent phenotypic revertants of the RQ strain, second-site mutations which affect Q sub(B) function are coupled to mutations in the Q sub(A) site which restore an Ala or substitute a Tyr at the M247 site; one strain carries an additional Met1Leu substitution at M260 near Q sub(A). All of the RQ revertants retain the engineered M246Ala1Glu mutation in the Q sub(A) site as well as the L212Ala-L213Ala mutations in the Q sub(B) site. Kinetic characterization of the RQ revertants will give us an idea of what structural and functional elements are important for restoring efficiency to electron and proton transfer pathways in the RQ RC, which is far from native. To date, these preliminary results underscore the importance of an asymmetric distribution of polar amino acids in the quinone binding pockets and its influence on the functional properties of the reaction center.

The higher delta (super 18) O values in the soil gas samples are due to the effects of diffusion and soil respiration (plant root and bacterial) on the isotopic O composition, while the lower delta (super 18) O in dissolved O (sub 2) at the Texas site indicates that O (sub 2) consumption below the root zone may be due to a different fractionation factor.

Specifically, the operable unit consists of the following areas and media: the residual material remaining at the Weldon Spring quarry after removal of the pond water and the bulk waste; groundwater underlying the quarry and surrounding area; and other media located in the surrounding vicinity of the quarry, including surface water and sediment at Femme Osage Slough, Little Femme Osage Creek, and Femme Osage Creek. An initial evaluation of conditions at the quarry area identified remaining data requirements needed to support the conceptual site exposure and hydrogeological models. These data requirements are discussed in the RI/FS work plan issued in January 1994. Soil contamination located at a property adjacent to the quarry, referred to as Vicinity Property 9 (VP9), was originally part of the scope of the QROU, as discussed in the work plan. However, a decision was subsequently made to remediate this vicinity property as part of cleanup activities for the chemical plant operable unit, as provided for in the Record of Decision (ROD). Remediation of VP9 was completed in early 1996. Hence, this baseline risk assessment (BRA) does not address VP9.

The impact of MS on soil microbial community structure and function is largely unknown. We investigated the effects of fumigation with field-relevant doses of MS in soil microcosms using traditional heterotrophic activity measures (C and N mineralization), a substrate-utilization assay, and fatty acid analysis. Our results suggest that fumigation with MS results in persistent changes (at least 18 wk) in heterotrophic activity and fatty acid composition of the microbial biomass. Lack of recovery of heterotrophic activity and changes in fatty acid composition after fumigation suggest that MS has the potential to alter important microbially mediated functions such as nutrient cycling and pollutant degradation. Preliminary fatty acid data suggest that actinomycetes and other gram-positive organisms may recover preferentially after fumigation with MS. Although community fatty acid analysis shows promise as a screening tool in soil microbial toxicity studies, more detailed information can be obtained from analysis of phospholipid fatty acid (PLFA) and other specific lipid fractions.

This study used Dravo's patented Thiosorbic+ lime process along with Argonne National Laboratory's (ANL's) patented process for combined SO sub(2)/NO sub(x) removal using the chelate ferrous.ethylenediaminetetraacetate (Fe.EDTA). For approximately nine months, scrubbing tests were carried out, and waste samples were collected. Waste testing at ANL involved two types of long-term chemical stability experiments. In one test, the gas-phase composition above several different samples was studied by mass spectrometry over 22 months. Unexpectedly, production of carbon dioxide and hydrogen sulfide was observed in some of the samples. The other experiment involved solid-phase leaching. Samples were stored for up to 14 months before leaching. Each leachate was tested for total Kjeldahl nitrogen and for the nitrogen-containing ions nitrite, nitrate, and ammonium. Significant amounts of ammonium ions were found in two of the samples. Total leachable nitrogen was found to stabilize after about the first 7 months of storage.

We generated and integrated the information contained in (1) a seismic hazard map compiled from peak horizontal ground acceleration and from earthquake epicenters, (2) a fault hazard map outlining surface (from geologic maps) and subsurface (from gravity field data) fault zones proximal to earthquake epicenters, (3) an amplification map showing the distribution of thick alluvium deposits that amplify ground shaking, (4) a liquefaction map showing areas susceptible (shallow groundwater, seismically active) to soil (sand/silt) liquefaction, and (5) a population density map that shows areas subject to increased risk of loss in human life and property. Frequent and large events in the scarcely populated southern Sinai, the coastal plain of the Gulf of Aqaba, and the coastal plain of the Red Sea and the Gulf of Suez (between latitudes 26'45' and 28'15'N) pose no seismic risk. Loss of human life and property is more likely to occur in areas of moderate seismicity (210 galP), and the substitution of Li for Zr explains why atomic P commonly exceeds atomic LREE in most synthetic zircons, a feature common to many natural zircons as well.

One such process involves grinding of solid waste to an average particle size of about one micrometer, followed by selective partitioning of the ultrafine particles between two immiscible aqueous phases. This aqueous biphasic separation process will recover most of the contaminants in a concentrate that has a volume of only a few percent of the initial waste volume.

H (sub 2) O AN - 1773797592; 2016-022613 AB - The low-temperature structure of hemimorphite, Zn (sub 4) Si (sub 2) O (sub 7) (OH) (sub 2) . H (sub 2) O, was investigated by neutron diffraction at 20 K using the "Time-Of-Flight" (TOF) method with a four-circle single-crystal diffractometer and a position-sensitive detector at the Intense Pulsed Neutron Source (IPNS) at the Argonne National Laboratory, IL. The reversible second-order phase transition, which had previously been determined at 98(2) K by optical measurements, was confirmed by two TOF neutron histograms acquired at 20 K and 120 K. Whereas the 20 K histogram showed superlattice reflections hkl with k, l = n/2 and intensities up to 30 sigma (I), these reflections were absent in the 120 K data set. In contrast to the room-temperature structure of hemimorphite (Imm2, a approximately 8.37 Aa, b approximately 10.73 Aa, c approximately 5.12 Aa), the additional reflections of the low-temperature structure lead to a supercell with a = 8.354(1) Aa, b = 21.519(4) Aa, c = 10.240(1) Aa. According to the general reflection conditions, the low-temperature superstructure of hemimorphite was refined in space group Abm2 (= Acm2 = Aem2) with Rw(F (super 2) ) = 0.058. Whereas the room-temperature structure shows dynamically disordered hydroxyl and H (sub 2) O groups, the low-temperature structure is characterized by an ordered arrangement of non-equivalent hydroxyl groups and rotated H (sub 2) O molecules linked by an enhanced H bond system along the channels of the structure, thus leading to a doubled c lattice parameter. A partially ordered arrangement of the channels across the structure (using the [1/2, 1/4, 1/4] or [1/2, 1/4, -1/4] translation vectors) results in doubling of the b lattice parameter. According to space group symmetry and additional non-space group reflection conditions 0kl with k + l = 4n and h00 with h = 2n, an order/dis-order (OD) structure model with microdomains and twinning is proposed.

While such small-scale results do not accurately predict process plant yields, they provide a useful reference in preliminary economic evaluations and in planning larger-scale tests. Therefore, on the basis of laboratory results, a commercial-scale catalytic pyrolysis plant for the production of synthetic crude oil was simulated by using Aspen Plus and the economics were developed. Depending on certain assumptions, such a process could be profitable. To test the possibility of producing chemicals, a separations plant was added. Simulation results again suggested potential economic viability.

Under the US Environmental Protection Agency's Alternative Treatment Standards, the preferred method of disposal of these wastes is macroencapsulation. Chemically bonded phosphate ceramic (CBPC) is a novel binder that was developed at Argonne National Laboratory to stabilize and solidify various low-level mixed wastes. This binder is extremely strong, dense, and impervious to water. In this investigation, CBPC has been used to demonstrate macroencapsulation of various contaminated debris wastes, including cryofractured debris, lead bricks, lead-lined plastic gloves, and mercury-contaminated crushed glass. This paper describes the fabrication of the waste forms, as well as the results of various characterizations performed on the waste forms. The results show that the simple and low-cost CBPC is an excellent material system for the macroencapsulation of debris wastes.

Most studies of the microbial metabolism of nitroaromatic compounds have used aerobic microorganisms. Ecological observations suggest that sulfate-reducing and methanogenic bacteria might metabolize nitroaromatic compounds under anaerobic conditions if appropriate electron donors and electron acceptors are present in the environment, but this ability had not been demonstrated until recently. Few review papers exist, and those deal mainly with aerobic bacterial degradation of explosives; none deals with anaerobic bacteria. In this paper, we review the anaerobic metabolic processes in the degradation of explosives and nitroaromatic compounds under sulfate-reducing and methanogenic conditions.

Anaerobic enrichment cultures were prepared from soil samples under various electron-accepting conditions, namely, sulfate-reducing, methanogenic, and nitrate-reducing conditions. The sulfate-reducing condition was very effective in removing all of the explosive compounds from the soil. The sulfate-reducing consortium removed 100% of 2,4,6-trinitrotoluene (TNT) and 1,3,5-trinitrobenzene (TNB) within 10-15 days of incubation and removed 75 to 95% of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetraazocine (HMX), within 21 days of incubation. The consortium used explosive compounds as the nitrogen source, however, it did not use these compounds as the sole carbon source. The various metabolites obtained from TNT metabolism were 4-amino-2,6-dinitrotoluene (4-A-2,6-DNT), 2,4-diamino-6-nitrotoluene (2,4-D-6-NT), and 2-methyl pentanoic acid. This sulfate-reducing consortium was further studied for its usefulness in removing TNT at the contaminated site. The results showed that the consortium can remove TNT under 5% and 10% soil slurry conditions. This laboratory study demonstrated that under anaerobic conditions, sulfate-reducing bacteria can be useful in the bioremediation of contaminated soil with TNT and other explosives.

AN - 79538642; 9450496 AB - The clinically approved cytoprotector amifostine, designated WR-2721, [S-2-(3-aminopropylamino)ethylphosphorothioic acid], protects against both radiation and drug-induced mutagenesis in animal systems. These effects extend over a wide concentration range making amifostine a strong candidate for evaluation as a possible cancer chemopreventive agent. To better identify and develop potential intermediate biomarkers for chemoprevention at the molecular level we applied the technique of differential display RT-PCR to assess the effects of both the thiol (SH), i.e. WR1065 and the disulfide (SS), i.e. WR-33278, metabolites of amifostine on gene expression in CHO-AA8 cells. Cells were exposed to either 40 microM or 4 mM of each agent for 30 min, and subsequent changes in gene expression were identified and contrasted to that found in corresponding untreated control cells. One band that showed a differential response was sequenced and was found to have 78% homology with a segment of the human pHL-1 cDNA clone contained in GenBank. This clone contains a COX III mitochondrial DNA insert and two exons of human c-myc. Northern blot analyses were performed by using the cloned human c-myc exon 1 probe to confirm whether c-myc gene expression was affected. Repression of c-myc expression was observed under all of the conditions evaluated. An exposure of cells to 40 microM of the disulfide form of amifostine was the most effective in repressing c-myc, i.e. 27% of control level. A concentration of 4 mM of the disulfide form reduced gene expression to 45% of the control level, while the thiol form was less effective, with 4 mM and 40 microM concentrations reducing c-myc gene expression to 65% and 46% of control levels, respectively.

The major objective of the ANL ESC is to determine whether a site containing contamination requires remediation. The methodology is equivalent to a CERCLA RI/FS or a RCRA RFI/CMS investigation. The ANL ESC methodology is an interactive, integrated process emphasizing the use of existing data, multiple complementary characterization methods, and on-site decision making to optimize site investigations. The ANL ESC is the basis for the expedited site characterization standard of the ASTM (American Society for Testing and Materials). The methodology has been registered under the service mark QuickSite (super TM) to offer both clients and providers a mechanism for ensuring that they receive the ANL ESC methodology developed by Argonne. The ANL ESC is a flexible process and is neither site nor contaminant dependent. It can be tailored to fit the unique characteristics that distinguish one site from the next, in contrast to the traditional approach of making all sites conform to the same rigid, inflexible investigation regimen. The ANL ESC has been applied successfully to remedial site investigations of landfills with multiple contaminants in the southwestern US for the Department of Interior (DOI), to former grain storage facilities in the Midwest for the Commodity Credit Corporation of the Department of Agriculture (CCC/USDA), to weapons production facilities in Texas for the Department of Energy (DOE), and to closing and active military bases in several locations for the Department of Defense (DOD). The process can be applied both at sites that have seen little investigation and at sites that have undergone numerous previous site characterizations without reaching closure. In the latter case (e.g., at many DOE and DOD sites), the ANL ESC offers a rapid solution, frequently with little additional field work.

Life-cycle costs associated with ITER construction, operation, and decommissioning are analyzed to assess their economic impact. A number of possible U.S. host and U.S. non-host technology and cost-sharing arrangements with the other ITER Parties are examined, although cost-sharing arrangements and the process by which the Parties will select a host country and an ITER site remain open issues. Both national and local/regional economic impacts, as measured by gross domestic product, regional output, employment, net exports, and income, are considered. These impacts represent a portion of the complex, interrelated set of economic considerations that characterize U.S. host and U.S. non-host participation in ITER. A number of other potentially important economic and noneconomic considerations are discussed qualitatively.

An alternative explanation, the pathogen transmission avoidance hypothesis, argues that the primary function of showy traits is to provide a reliable signal of current disease status, so that sick individuals can be avoided during mating. This study shows that a significant risk of pathogen transmission occurs during mating and that showy traits are reliable indicators of current disease status. A simulation model of population dynamics linked with pathogen transmission indicates that female choosiness traits are selectively advantageous and spread through the population but because the selective benefit of choosiness depends on the percentage of choosy females and bright males, as sexual selection proceeds the selection pressure is reduced and the process becomes self-limiting rather than runaway. Thus, an epidemic model approach leads to very different conclusions than a constant selection-coefficient population genetic approach. The origin of female choosiness is argued to lie in a general tendency to avoid sick individuals, even in the absence of showy traits, which originate as exaggerations of normal traits that are indicative of good health (bright feathers, vigorous movement, large size). Thus, in this new model the origins of both showy traits and female choosiness are not problematic and there is no threshold effect. This model predicts that when the possession of male showy traits does not help to reduce disease in the female, showy traits are unlikely to occur. This case corresponds to thorough exposure of every animal to all group pathogens, on average, in large groups. Such species are shown with a large data set on birds to be less likely to exhibit showy traits. The good-genes model does not make this prediction. The pathogen transmission avoidance model can also lead to the evolution of showy traits even when selection is not effective against a given pathogen (e.g. when there is no heritable variation for resistance), but can result in selection for resistance if such genes are present. Monogamy is argued to reduce selection pressures for showy traits; data show monogamous species to be both less parasitized and less showy. Overall, the pathogen transmission avoidance hypothesis provides a complete alternative to the good-genes theory and makes new predictions.

A suite of 16 analytical tests involving 11 different SW-846 methods was used to detect a wide range of organic and inorganic contaminants. One method (BTEX) was considered redundant, and two "single-number" methods (TPH and TOX) were found to lack the required specificity to yield unambiguous results, especially in a preliminary investigation. Volatile analytes detected at the site include 1,1,2,2-tetrachloroethane, trichloroethylene, and tetrachloroethylene, all of which probably represent residual site contamination from past activities. Other volatile analytes detected include toluene, tridecane, methylene chloride, and trichlorofluoromethane. These compounds are probably not associated with site contamination but likely represent cross-contamination or, in the case of tridecane, a naturally occurring material. Semivolatile analytes detected include three different phthalates and low part-per-billion amounts of the pesticide DDT and its degradation product DDE. The pesticide could represent residual site contamination from past activities, and the phthalates are likely due, in part, to cross-contamination during sample handling. A number of high-molecular-weight hydrocarbons and hydrocarbon derivatives were detected and were probably naturally occurring compounds.

To a first approximation, the development of stratigraphic sequences at these scales is a function of eustatic sea level change, which is global in scope, and sediment supply and subsidence, which are regional. Both sea level and sediment supply, in turn, are controlled by global and regional climate. As a result, there has been a great of interest in attempting to model and assess the extent to which astronomical cycles are expressed in the stratigraphic record [1, 2]. In this paper we will describe how the recently developed technique of lacunarity analysis can be applied to the study of cyclic stratigraphic sequences and can be used as a tool for model validation and data comparison by cyclostratigraphers. We apply this method to a model marine siliciclastic sequence in which both sea level and sediment supply are linearly driven by orbital cycles. Our results suggest that recognition of cyclic signals in these systems, even in ideal situations, may be problematic. JF - Proceedings of the ...

The authors used an optimality argument to predict how much a tree should respond to sidelight. Their calculations of the costs of leaning are flawed, because: (i) leaf mass has an allometric relationship with total volume, rather than being a fixed proportion of wood mass; (ii) the cost of support wood tissue is mainly a growth rate cost, not a maintenance respiration cost; (iii) small trees are sufficiently elastic to need very little support tissue, and thus they have a different risk structure; and (iv) most crown gaps are ephemeral rather than permanent, which also changes the risk equation. The argument I proposed in a previous study, addressing exactly the same question, is that canopy species are under selective pressure to maintain a strong central trunk that will reach the canopy and thus should not respond to sidelight. A reproductive value model is presented to illustrate this evolutionary question. Small, short-lived species or those from habitats with permanent openings (such as river margins) should be responsive. Both my previous data and the data of the other study support my model, but the model in the other study leaves many facts unexplained.

Because of the rapid, polythermal modes of zircon growth and the high Pb content of the experimental systems, the resulting apparent partition coefficients should not be viewed as equilibrium values, but as qualitative indicators of Pb compatibility in various growth circumstances. The overall results are consistent with the low but variable levels of non-radiogenic Pb in natural zircons. The increased compatibililty of Pb in fluid-grown, low-T zircons suggests a possible fingerprint for zircons from hydrothermal and wet-metamorphic rocks, i.e. high concentrations of common Pb.

Analyses include N, S, total C, organic C, Delta (super 13) C (sub total) , Delta (super 13) C (sub org) , Delta (super 34) S and Fe (sub 2) O (sub 3) . Kerogen-enriched samples are analysed for N, C, H, S and Fe. The average N/C ratios of the kerogens are generally lower than those of bulk rocks indicating the N (sub 2) is mostly fixed in clay minerals, possibly as NH (super +) (sub 4 ) rather than in organic matter. In theory, the initial C (sub org) contents of the Kaapvaal shales were five times the measured values; the original C (sub org) in the late Archaean and early Proterozoic from the craton is estimated at 2.45 and 2.15 wt.%, respectively, and similar to average C (sub org) of modern marine sediments. Delta (super 34) S values of sulphides indicate pyrite formation from H (sub 2) S generated by bacterial reduction of sea-water sulphate. Based on the C (sub org) and sulphide S results, the Kaapvaal shales from the central and E regions are divided into three groups representing different depositional environments. Development of anoxic basins and implications for detrital uraninite and pyrite are discussed.

AN - 79128450; 9221825 AB - Cadmium (Cd) exposure induces bone resorption in vitro and in vivo that can lead to low bone mass and increased incidence of fracture. We have developed an animal model for following the early skeletal response to Cd. A low-calcium (but not calcium-deficient) diet is used to increase gastrointestinal absorption of calcium so that the endogenous fecal calcium excretion is essentially the total fecal calcium excretion. The bone response is followed by quantitation of stable fecal calcium and does not require a radioactive label. After mice were adjusted to a low-calcium diet, Cd was administered by a single gavage and fecal calcium was monitored to determine the magnitude of the calcium release from bone. Fecal calcium excretion (microg Ca/hr; mean +/- SE) remained at the background level for 8 hr (13.6 +/- 1.8, n = 18) but increased during the 8- to 24-hr and 24- to 56-hr collection periods (43.8 +/- 6.8, n = 12; 50.75 +/- 3.7, n = 6, respectively). The bone response was transient and dropped to nearly background levels during the 56- to 104-hr collection period. Blood calcium levels were normal throughout the time course. Bone resorption occurred at Cd levels of 7.9 +/- 0.7 microg/liter blood (mean +/- SE, n = 6), which is in the range of occupational exposure levels. The transient nature of the bone response contrasted to the slow but continuing rise observed in blood Cd levels. These results suggest that a threshold level of Cd is required for a bone response but that chronic levels of Cd in blood do not necessarily indicate the occurrence of continuous active bone resorption. This model can be used to probe early gene changes (prior to the bone response) that may be occurring in response to Cd exposure.

AN - 79047343; 9175563 AB - Swine manure contains diverse groups of aerobic and anaerobic bacteria. An anaerobic bacterial consortium containing sulfate-reducing bacteria (SRB) and acetate-utilizing methanogenic bacteria was isolated from swine manure. This consortium used phenol as its sole source of carbon and converted it to methane and CO2. The sulfate-reducing bacterial members of the consortium are the incomplete oxidizers, unable to carry out the terminal oxidation of organic substrates, leaving acetic acid as the end product. The methanogenic bacteria of the consortium converted the acetic acid to methane. When a methanogen inhibitor was used in the culture medium, phenol was converted to acetic acid by the SRB, but the acetic acid did not undergo further metabolism. On the other hand, when the growth of SRB in the consortium was suppressed with a specific SRB inhibitor, namely, molybdenum tetroxide, the phenol was not degraded. Thus, the metabolic activities of both the sulfate-reducing bacteria and the methanogenic bacteria were essential for complete degradation of phenol.

However, these disposal methods often contaminated soil and groundwater with organic compounds and metals that require cleanup under current regulations. An emerging technology for cleaning contaminated soils and shallow groundwater is phytoremediation, an environmentally friendly, low- cost, and low-tech process. Phytoremediation encompasses all plant-influenced biological, chemical, and physical processes that aid in the uptake, degradation, and metabolism of contaminants by either plants or free-living organisms in the plant's rhizosphere. A phytoremediation system can be viewed as a biological, solar-driven, pump-and-treat system with an extensive, self-extending uptake network (the root system) that enhances the soil and below-ground ecosystem for subsequent productive use. Argonne National Laboratory (ANL) has been conducting basic and applied research in phytoremediation since 1990. Initial greenhouse studies evaluated salt-tolerant wetland plants to clean UP and reduce the volume of salty "produced water" from petroleum wells. Results of these studies were used to design a bioreactor for processing produced water that is being demonstrated at a natural gas well in Oklahoma; this system can reduce produced water volume by about 75% in less than eight days, representing substantial savings in waste disposal cost.

A total of 80 lung tissue samples from irradiated mice and 40 lung samples from nonirradiated controls were selected randomly and examined in the Rb portion of this study. The results showed a significantly (P 0.05) from that for spontaneous lung adenocarcinomas or lung adenocarcinomas from mice exposed to single-dose gamma irradiation at a similar total dose. Rb fragments 3 (71%) and 5 (67%), the parts of the gene that encoded the pocket binding region of Rb protein to adenovirus E1A and SV40 T-antigen, were the most frequently deleted fragments. Analysis of p53 gene deletion was carried out on normal lungs and lung adenocarcinomas that were initially found to bear Rb deletions. Exons 1, 4, 5, 6 and 9 were chosen to be analyzed. The data showed that 30 (97%) of 31 normal lungs and lung adenocarcinomas had p53 deletions. Exons 4 (83%) and 5 (90%) were the most frequently deleted among tested exons. Mice exposed to neutrons 60 times on a once-weekly schedule had a higher percentage of complete p53 deletions (5/8; 63%) than those exposed to gamma rays 60 times on a once-weekly schedule (2/8; 25%). We conclude that p53 deletions may be one of the major mutational events in the tumorigenesis of lung adenocarcinomas in the irradiated B6CF sub(1) mice.

AN - 79058096; 9189169 AB - The mortality pattern of women who began employment as luminizers in the radium dial industry before 1930 was followed through 1990. Hazard models with time-dependent covariates were used on mortality data either organized by individual death times or grouped into cross-classified person-year tables. These models were used to quantify trends in mortality associated with either death from or diagnosis of bone sarcoma or head carcinoma. The accumulation of skeletal doses from 226Ra and 225Ra was an important predictor of the risk of death from bone sarcoma. Women exposed to 226Ra at ages associated with active bone growth were at greater risk of bone sarcoma than women receiving even larger exposures at an age when their skeletons would have been fully developed. Exposure to only 226Ra was found to be an important predictor of risk for carcinoma of the mastoid air cells and paranasal sinuses. For the cranial sites, where adult dimensions are attained early in life, an effect of age at exposure could not be detected.

AN - 78956485; 9106724 AB - Seventeen Region III nuclear stations originated and participated in an intercomparison study of their whole body counting procedures using the same calibration standard. The first phase of the study involved transporting a phantom containing four reactor-produced radionuclides and 40K to each plant. The plant staff were asked to follow all procedures applicable for a human subject including routine and investigative counts, if necessary, and to provide a printout of the results to the project investigators. The results from each plant were normalized for intercomparison by calculating the ratio of the reported activity to the actual activity after correcting for the appropriate amount of decay to the time of the count. Five plants reported 60Co values outside 1 standard deviation (SD) of the mean for 60Co and one plant did not detect the presence of 60Co. According to previously established procedures, these six plants were revisited after a period of time in which internal recalibration and corrective actions could be made. Four of the six plants had results which were still outside 1 SD of the mean for the original study. A final report in coded form to protect plant anonymity was provided to those stations to guide them in making further improvements, if they chose to do so.

The timing of humid intervals called pluvials was investigated by uranium-series disequilibrium dating of travertines from the Kurkur Oasis, Western Desert, Egypt. The youngest and best dated travertines (70-160 ka) are found in Wadi Kurkur and include spring and lacustrine units exposed as 2 to 3m high terraces. Travertines having an age of approximately 191-220 ka are exposed by differential erosion as linear mounds produced by spring systems over fracture zones in ancient wadis. The oldest travertines, having ages >260 ka, are extensive, cap limestone units above the oasis, and were deposited in paludal and lacustrine environments. Oxygen isotope ratios were measured for the wadi travertines (delta (super 18) O values ranging from 16.7 to 19.1 per mil SMOW) and for spring mound travertines (18.5-20.5 per mil). Equilibrium oxygen isotope fractionation calculations indicate that the Kurkur travertines were deposited from waters having delta (super 18) O values similar to ancient Western Desert groundwaters ( approximately -11 per mil, Sonntag et al., 1978a,b; Thorweithe, 1990; Sultan et al., 1996). The ages of the travertines correspond to times of monsoonal maxima, eustatic sea level high stands and interglacial maxima. Rainfall producing these groundwaters (and travertines) was significantly fractionated during atmospheric transport, in contrast to modern meteoric waters (-2.09 per mil, Joseph et al., 1992), implying a distant source for the pluvial waters. Increased precipitation, recharge of Western Desert groundwaters, and resultant travertine deposition are interpreted to be consequences of Milankovitch insolation cycle forcing, through enhanced Atlantic and Indian Ocean monsoons during interglacial time periods.

The surveillance program is the ongoing remedial action that resulted from the 1976-1978 radiological characterization of the site. That study determined that very low levels of hydrogen-3 (as tritiated water) had migrated from the burial ground and were present in two nearby hand-pumped picnic wells. The current program consists of sample collection and analysis of air, surface and subsurface water, and bottom sediment. The results of the analyses are used to (1) monitor the migration pathway of water from the burial ground (Plot M) to the hand-pumped picnic wells, (2) establish if buried radionuclides other than hydrogen-3 have migrated, and (3) generally characterize the radiological environment of the area. Hydrogen-3 in the Red Gate Woods picnic wells was still detected this year, but the average and maximum concentrations were significantly less than found earlier. Tritiated water continues to be detected in a number of wells, boreholes, dolomite holes, and a surface stream. For many years it was the only radionuclide found to have migrated in measurable quantities. Analyses since 1984 have indicated the presence of low levels of strontium-90 in water from a number of boreholes next to Plot M. The available data does not allow a firm conclusion as to whether the presence of this nuclide represents recent migration or movement that may have occurred before Plot M was capped. The results of the surveillance program continue to indicate that the radioactivity remaining at Site A/Plot M does not endanger the health or safety of the public visiting the site, using the picnic area, or living in the vicinity.

Conserved residues that break the twofold symmetry in this region of the RC - M246Ala and M247Ala in the QA binding pocket, and L212Glu and L213Asp in the QB binding pocket - were targeted. We constructed a QB-site mutant, L212Glu-L213Asp 1 Ala-Ala, and a QA-site mutant, M246Ala-M247Ala 1 Glu-Asp, to partially balance the differences in charge distribution normally found between the two quinone binding sites. In addition, two photocompetent revertants were isolated from the photosynthetically-incompetent M246Glu-M247Asp mutant: M246Ala-M247Asp and M246Gly-M247Asp. Sequential electron transfer was investigated by continuous light excitation and time-resolved electron paramagnetic resonance (EPR), and time-resolved optical techniques. Several lines of EPR evidence suggested that the forward electron transfer rate to QA, kQ, was slowed in those strains containing altered QA sites. The slower rates of secondary electron transfer were confirmed by time-resolved optical results with the M246Glu-M247Asp mutations in the QA site resulting in a dramatically lowered secondary electron transfer efficiency [kQ < (2 ns)-1] in comparison with either the native R. capsulatus RC or the QB site mutant [kQ - (200 ps)-1]. Secondary electron transfer in the two revertants was intermediate between that of the native RC and the QA mutant. The P+ QA- 1 PQA charge recombination rates were also changed in the strains that carried altered QA sites. We show that local mutations in the QA site, presumably through local electrostatic changes, significantly alter binding and electron transfer properties of QA.

AN - 78991518; 9150944 AB - As sequencing of the human genome progresses, attention is turning to when and where specific genes are being expressed and how that expression is regulated. The human breast, with the highly specific, but transient, function of milk production (lactation), exemplifies human gene regulation. The molecular mechanisms for the dramatic structural and functional changes involved in shifting from lactation-capable to lactation-incapable tissue are poorly understood, as are the mechanisms that result in deviation from normal breast cell growth into different types of breast neoplasms. We are using quantitative two-dimensional electrophoresis (2-DE) to determine which proteins are present in different types of human breast cells (milk-producing and -nonproducing, estrogen-receptor-positive and -negative, normal and malignant) and which proteins change in abundance in response to stimuli that trigger cell differentiation, growth, or death. A composite map of proteins found in human breast cells is being generated and used as an index of human genes that are differentially expressed, both qualitatively and quantitatively. Proteins found in 15 different types of human breast cells, two from healthy tissue (from milk and reduction mammoplasty tissue) and 13 from tumor tissue, are now included in the composite map. Copies of the human breast epithelial cell protein map are available on the World Wide Web (URL: http:(/)/www.anl.gov/CMB/PMG/ projects/index_hbreast.html) with links to quantitative data and identifications for proteins found to be differentially expressed in these epithelial cells. Links to the Swiss-Prot and enzyme metabolic pathway databases are also provided. The World Wide Web presentation is designed to allow public access to the available 2-DE data together with logical connections to databases providing genome-related information.

Complete crystallization occurs upon aqueous reflux for 48 h. The progress of clay layer formation was monitored by X-ray powder diffraction (XRD), differential thermal gravimetry (DTG), and infrared (IR) spectroscopy. Evidence of clay XRD peaks occurs after just 4 h of hydrothermal treatment, and Mg(OH) (sub 2) is no longer observable after 14 h. Observable changes in DTG and IR occur at about this time as well. Warren line-shape analysis of the 110 reflection indicates that when growth is complete the clay lamellae are on average approximately 50% and 25% of the size of natural hectorites and montmorillonites, respectively. The N (sub 2) BET surface areas for all materials are also compared. Small angle neutron scattering shows that addition of tetraethyl ammonium (TEA) ions does not alter the structural integrity over that of the purely inorganic form of Li-hectorite, but that use of a cationic polymer does significantly alter the microstructure. The effect of temperature is critical, for at room temperature only the layered Mg hydroxide mineral brucite crystallizes unless very long time scales are used. The crystallizations carried out at room temperature show that clay will form after about 3 months, but that the presence of organics (at least TEA) acts to hinder this process greatly. The role of the organic molecules on silicate clay layer formation is compared with the role of organics in zeolite synthesis.

This data set furthers our understanding of the hydrogeologic framework by identifying paleochannel locations, delineating paleochannel geometries, and characterizing relationships between multiple generations of paleochannels. Fine-grained bottom sediment resting in deeper, low-energy waters were found to block high-frequency acoustic wave transmission; therefore, data acquisition is limited to areas near-shore were water depths are less than three meters. Approximately 120 km of shoreline were surveyed yielding 50 km of high quality data. Three major reflectors are identified as erosional unconformities, and are interpreted to be Pleistocene paleochannel surfaces. Paleochannels are found to be spatially and physiographically associated with all modern subaerial lowlands and their local drainage systems. The marine seismic reflection data provide strong evidence that present-day lowlands are underlain by an aquifer dominated by paleochannels. Paleochannel configurations, together with paleochannel-fill models, indicate these paleochannels have the potential support vertical and horizontal contaminant migration.

Geologic models indicate that solution activity occurs at the loess-bedrock interface, and is concentrated along loess-filled fracture trends within the underlying carbonate bedrock. Soil arches that develop along these fracture trends have the potential to fail catastrophically, posing a considerable degree of danger to current training activities. Rapid, continuously recording electromagnetic instruments provide an economical solution for locating zones of high conductivity associated with loess-filled fractures. The electromagnetic surveys delineated high-conductivity trends interpreted to be fracture-controlled. In many instances dolines were observed either along or immediately adjacent to these conductivity lineaments. Analysis of anomaly maps indicate that high-conductivity lineaments are aligned subparallel to fracture and joint orientations measured in nearby outcrops. These associations are the basis for predicting locations where solution cavity collapse and doline development will occur in the future. Information derived from the EM data can be extended directly to hydrologic modeling and to safety programs for military training at the CMTC.

The volcanic rocks contain 222-347 ppm REE and their chrondrite-normalized patterns with LREE >> HREE and -ve Eu anomalies agreeing with those for the upper continental crust. The REE are mobile during water-rock interaction, and are removed during alteration processes except for Eu which is enriched in the altered rocks. The REE are released into solution during dissolution of minerals and/or glass from the rhyolites by low-pH fluids; there is little REE fractionation during fluid/rock interaction indicating that the main complexing agent is sulphate or that REE mobility is not increased by complexing agents. The main factor affecting the mobilization and transport of REE is pH.

AN - 78787963; 9002439 AB - In earlier studies (Boopathy et al. 1994a, 1994b), soil bacteria present in a TNT-contaminated site removed 2,4,6-trinitrotoluene (TNT). In this study the optimum conditions for the most efficient removal of TNT is discussed. The results suggest that the soil bacterial consortium has an optimal pH range of 6-7. Maximum growth was observed at pH 7. However, the TNT removal rate was higher at pH 6. Studies of the effects of temperature showed that the bacterial consortium had maximum metabolic activity at 20 to 22 degrees C (ambient temperature). At a higher temperature (37 degrees C) the TNT removal rate dropped significantly. The consortium could not use TNT as a nitrogen source but required the addition of ammonium. Optimal growth occurred with 0.25 g/L of ammonium chloride. Growing cells removed TNT significantly faster rates than resting cells or cell-free extract. The operation of soil slurry reactors with the optimal conditions suggested that TNT can be removed effectively from the contaminated sites. These environmental conditions established as optimal can be used to improve the efficiency of large-scale soil slurry reactors for the treatment of soil contaminated with TNT.

Scallop-shaped escarpment edges and stubby-looking channels that cut into the plateau units are suggestive of slumping of limestones by ground-water sapping at the limestone-shale interfaces, removal of slump blocks by weathering and fluvial erosion, and consequent scarp retreat. Spring-derived tufa deposits found near the limestone escarpments provide additional evidence for possible ground-water sapping during previous wet periods. A computer simulation model was developed to quantify the ground-water sapping processes, using a cellular automata algorithm with coupled surface runoff and ground-water flow for a permeable, resistant layer over an impermeable, friable unit. Erosion, deposition, slumping, and generation of spring-derived tufas were parametrically modeled. Simulations using geologically reasonable parameters demonstrate that relatively rapid erosion of the shales by surface runoff, ground-water sapping, and slumping of the limestones, and detailed control by hydraulic conductivity inhomogeneities associated with structures explain the depressions, escarpments, and associated landforms and deposits. Using episodic wet pulses, keyed by delta (super 18) O deep-sea core record, the model produced tufa ages that are statistically consistent with the observed U/Th tufa ages. This result supports the hypothesis that northeastern African wet periods occurred during interglacial maxima. The delta (super 18) O-forced model also replicates the decrease in fluvial and sapping activity over the past million years, as northeastern Africa became hyperarid. The model thus provides a promising predictive tool for studying long-term landform evolution that involves surface and subsurface processes and climatic change.

XSW measurements are used to triangulate the location of the Pb ions and confirm that they occupy Ca sites in the calcite lattice. In situ X-ray reflectivity measurements indicate that the Pb ions occur mainly in the surface layer of calcite rather than above or below that surface. Quantitative morphological data from atomic force microscopy is used to test models used in calculating the X-ray reflectivity intensities. These specialized X-ray techniques are briefly described.

Such applications include source apportionment and isotopic mass balance of natural attenuation in contaminated groundwater aquifers. Before these applications can be widely used, however, it is necessary to understand the magnitude and direction of isotopic fractionation that may accompany chemical and biological dehalogenation reactions involving chlorinated ethenes. The reaction examined in the present work is the reductive dehalogenation of chlorinated ethenes with zero-valent Fe. This is a widely applied remediation technique for chlorinated solvents. Replicate experiments were performed with tetrachloroethylene (PCE), trichloroethylene (TCE) and 1,2-cis-dichloroethylene (DCE) in 254 ml reaction vessels. Headspace was sampled either with gas tight syringes or solid phase microextraction and analysed by GC-C-IRMS for carbon isotope ratio measurements and by the Holt et al. (Anal. Chem., 1997) method for chlorine isotope ratio measurements.During the reaction with electrolytic Fe, all residual compounds became enriched with 13-C. A carbon isotope ratio increase from -30.5 to -16.8 per mil after 170 hrs was noted for TCE, whereas a similar increase from -26.8 to -5.3 per mil after 288 hrs was noted for DCE. The experiments with PCE are currently in progress, with a 13-C enrichment of 11 per mil noted after 48 hours. Chlorine isotope measurement also are in progress and will be presented. The results of our work indicate the utility of compound-specific carbon and chlorine isotopic measurements in tracing reaction progress of reductive dehalogenation in laboratory and field systems. The systematic nature of the isotopic fractionation implies that source apportionment of partially degraded chlorinated ethenes also may be possible.

Two TCE-contaminated plumes extend northward in the regional gravel aquifer from residual DNAPL pool(s) within the PGDP property toward the Ohio River. Fifteen monitoring wells (including two uncontaminated background wells) were sampled during May 1997 for a preliminary isotopic investigation. The objectives of this investigation of stable isotope ratios (of C and Cl in TCE; dissolved inorganic C; inorganic Cl; and oxygen in water) are: (1) to determine the possible extent of natural TCE attenuation; (2) to determine whether the two plumes could have different TCE sources; and (3) to determine whether the contaminated plumes could have different water sources, as evidenced by variations in oxygen isotope ratios of water.The groundwater characteristics are: pH, 6.3-8.0; Eh, +120 to +280 mV; bicarbonate, 99-351 mg/L; chloride, 3-120 mg/L; sulfate, 5.5-115 mg/L; nitrate, <0.5-50 mg/L; total Fe, <0.3-7.0 mg/L; H2S, <0.01-0.04 mg/L; ammonia, <0.1 mg/L; TCE, <0.001 to 180 mg/L; cis-1,2,-DCE, <0.001-0.130 mg/L. Carbon isotope ratios of TCE were determined by GC-C-IRMS and range from -30.4 to -26.7 per mil [PDB]. Chlorine isotope ratios of TCE were determined by the method of Holt et al. (Anal. Chem. 1997) and range from -1.0 to -0.2 per mil [SMOC]. Oxygen isotope ratios of water range from -5.8 to -4.9 per mil [SMOW]. The isotopic data indicate minor degradation of TCE, little or no difference in source composition of TCE in the two plumes, and no difference in water source for the two plumes. These conclusions are consistent with the relatively low DCE/TCE concentration ratios in the plumes (<0.00008 to 0.022) and the generally oxidizing conditions of the aquifer.

Possible sources are thought to be: Nile River water, flash-flood water stored in shallow aquifers, and Nubian aquifer paleowater that may have ascended under artesian pressure along faults. The examined waters from the Eastern and Western Deserts of Egypt have isotopic compositions that are quite distinct from the Nubian aquifer paleowaters and are generally less enriched in D and 18-O than Nile River water. The Eastern Desert water samples plot mostly along the global meteoric water line at values equal to or greater than those of Sidi Barrani rain waters. The Western Desert water samples plot mostly along an evaporation line with a slope of 5.9 and have isotopic compositions intermediate between Sidi Barrani rainwater and Nile River water. The Western Desert waters have undetectable tritium activities, whereas the Eastern Desert samples with one exception have tritium activities indicative of post-bomb precipitation. Results indicate that: 1) flash-flood waters stored in shallow aquifers appear to be the principal source of most of the groundwaters analyzed, 2) none of the groundwaters have a significant component of Nubian aquifer paleowater, and 3) the Eastern Desert waters are relatively older (>45 years) than the Western Desert waters (<45 years).

These species present a significant challenge to cost-effective remediation of contaminated environments. An attractive approach to decreasing the probability of actinide migration in the subsurface is to transform the ions into a less mobile form by remote treatment. We have under development a process which relies on a polyfunctional organophosphorus complexant to sequester the mobile metal ions by complexation/cation exchange in the near term, and to subsequently decompose, transforming the actinides into insoluble phosphate mineral forms in the long term. Studies to date include identification of a suitable organophosphorus reagent, profiling of its decomposition kinetics, verification of the formation of phosphate mineral phases upon decomposition of the reagent, and extensive comparison of the actinide uptake ability of the calcium salt of the reagent as compared with hydroxyapatite.

The determination of an "average" emission rate for a given field site requires sampling designs and statistical techniques which consider spatial and temporal variability. Moreover, particularly at sites with pumped gas recovery systems, it is possible for methanotrophic microorganisms in aerated cover soils to oxidize all of the methane from landfill sources below and, additionally, to oxidize methane diffusing into cover soils from atmospheric sources above. In such cases, a reversed soil gas concentration gradient is observed in shallow cover soils, indicating bidirectional diffusional transport to the depth of optimum methane oxidation. Recovery of landfill methane through engineered systems can provide both environmental and energy benefits by mitigating subsurface migration, reducing surface emissions, and providing an alternative energy resource for industrial boiler use, on-site electrical generation, or upgrading to a substitute natural gas.

The compounds included 2, 4, 6-trinitrotoluene (TNT), hexahydro-1, 3, 5 - trinitro-1, 3, 5-triazine, octahydro-1, 3, 5, 7-tetranitro- 1, 3, 5, 7-tetraazocine, 2, 4, 6-trinitrobenzene (TNB), and 2, 4-dinitrotoluene. All of the compounds studied were degraded by the sulfate reducing bacterial (SRB) enrichment culture. The SRB culture did not use the munitions compounds as their sole source of carbon. However, all the munitions compounds tested served as the sole source of nitrogen for the SRB culture. Degradation of munitions compounds was achieved by a co-metabolic process. The SRB culture used a variety of carbon sources including pyruvate, ethanol, formate, lactate, and H (sub 2) -CO (sub 2) . The SRB culture was an incomplete oxidizer, unable to carry out the terminal oxidation of organic substrates to CO (sub 2) as the sole product, and it did not use acetate or methanol as a carbon source. In addition to serving as nitrogen sources, the munitions compounds also served as electron acceptors in the absence of sulfate. A soil slurry experiment with 5% and 10% munitions compounds-contaminated soil showed that the contaminant TNT was metabolized by the SRB culture in the presence of pyruvate as electron donor. This culture may be useful in decontaminating munitions compounds-contaminated soil and water under anaerobic conditions.

Our work suggests that the presence of a polar icecap can be confirmed by establishing the asymmetry in the thicknesses of the marine stratigraphic record of the northern and southern hemispheres produced by the interaction of precession-scale sediment yield and glacioeustatic cycles. Hemispheric asymmetry should not exist in an ice free world. If our hypothesis is correct, it will permit substantial refinements in interpreting the stratigraphic record, leading to refined exploration techniques. In periods of unipolar glaciation, higher sea level will occur during the precessional climate maximum in the glaciated hemisphere, when the opposing hemisphere is at a precessional climate minimum. Through most of the Phanerozoic, until the Plio-Pleistocene, large landmasses in polar latitudes occurred predominantly in the southern hemisphere, precluding a large northern polar glacier. When ice did exist at the southern pole, the southern hemisphere precessional climatic maximum coincided with sea level highstands, while the northern hemisphere precessional climatic maximum coincided with sea level lowstands. Sediment yield cycles from areas with the same climatic succession but located in opposite hemispheres will have two distinct phase relationships with glacioeustasy, creating different stratigraphic architectures. This will produce statistically different patterns of bed thickness distributions.

Accurate knowledge of the mechanisms and rates of heterogeneous nucleation and growth of minerals is needed to develop realistic models of low-temperature geochemical systems. For example, growth and dissolution relationships between gibbsite and kaolinite are key to understanding weathering processes that lead to laterite and bauxite formation. We have developed a precise and accurate X-ray diffraction (XRD) method for measuring amounts of epitaxially grown gibbsite on kaolinite, using a custom built rotating-anode X-ray diffractometer (M. Beno and G. Knapp, Rev. Sci. Instr., 1993) at Argonne National Laboratory. This method can yield kinetic and structural data for analogous heteroepitaxial growth of many minerals.The method was calibrated using mechanical mixtures of gibbsite and kaolinite. Integrated peak areas from powder XRD scans for the kaolinite (001) and gibbsite (002) diffraction peaks were plotted against weight fractions of mechanical mixtures of gibbsite and kaolinite. The range of calibration is from 0 to 20 wt. percent gibbsite, and the regressed data show a near perfect linear correlation. Using a position sensitive detector and a high operating current (150-200 mA at 40 kV), we obtained good counting statistics and a low detection limit for gibbsite (0.1 wt. %).In a set of ongoing experiments, we are growing gibbsite on kaolinite powders at 80AC, pH 3 under variable saturation state conditions with respect to both phases. The preliminary XRD results obtained thus far on these experimental samples agree well with solution chemistry mass balance and with atomic force microscopy images. The XRD data verify that gibbsite was in the run products. The XRD data also can provide information on the epitaxy between gibbsite and kaolinite and on the average gibbsite domain size.

These cycles involve a chemical reaction to capture O sub(2) from the air and a change in the operating conditions to effect a controlled breakdown of the newly formed product to release the O sub(2) and regenerate the original species. These cycles are generally more expensive than cryogenic separation of air, partly because they consume high-temperature thermal energy (500-850 degree C). The chemical cycles can be integrated with high-temperature power cycles to provide efficient heat cascading and recovery because the different temperature levels at which they require thermal energy are compatible with the levels encountered in high-temperature power cycles. The O sub(2) can be used in the combustion process to generate a CO sub(2)-rich stream that is more readily separable for production of commercial-grade CO sub(2). This paper presents a preliminary discussion of such integrated systems to facilitate the capture of CO sub(2), aimed at reviving interest in these cycles. JF - ENERGY CONVERS. MANAGE.

The ACA is an extendible computer based decision support system for developing air pollution compliance strategies. It was developed to assist environmental personnel to achieve and maintain compliance with applicable regulations and permit conditions. It accomplishes this by providing a framework for collecting site-specific data, providing reliable estimates of emissions in the absence of actual data, providing estimates of pollution control options' efficiencies and costs, and integrating the functionality of regulatory requirements for federal facilities to determine what regulations may apply. While the software was developed initially for use by the U.S. Department of Defense (DoD), these capabilities are clearly useful to industry and regulators both in the U.S. and Canada. The possible uses of the ACA from a regulator's perspective are discussed using the specific situation of the Ontario Ministry of Environment and Energy (MOEE) to highlight what can be done with the existing package and where extensions might be useful.

The obvious air quality benefit of pure electric vehicles is that they produce no tailpipe emissions. Hybrid electric vehicles (HEVs) have the potential of improving fuel economy and reducing emissions. However, both electric vehicles and hybrid electric vehicles do have their own environmental impacts. In order to quantify the potential benefits from introducing such vehicles, it is necessary to compare their impacts with those from the conventional vehicles they would replace. These impacts include energy use and emissions from the entire energy cycle, including fuel production, vehicle and battery production and recycling, and vehicle operation. Argonne's previous work in collaboration with other national laboratories analyzed the total energy cycle of electric vehicles; this paper compares energy use and emissions for the total energy cycle of several HEV designs with those from modern conventional vehicles. The results show that use of HEVs can reduce energy use and emissions of greenhouse gases, volatile organic gases, carbon monoxide, and particulate matter with size smaller than 10 microns. HEVs may, in some cases, increase emissions of nitrogen oxides and sulfur oxides. JF - AIR & WASTE MANAGEMENT ASSOCIATION 90. ANNUAL MEETING.

N1 - Last updated - 2011-12-13 ER - TY - BOOK T1 - Lifecycle analysis: uses and pitfalls AN - 16366486; 4262867 AB - There has been a recent trend toward the use of lifecycle analysis (LCA) as a decision-making tool. However, the different practitioners' methods and assumptions vary widely, as do the interpretations put on the results. The lack of uniformity has been addressed by such groups as the Society of Environmental Toxicology and Chemistry (SETAC) and the International Organization for Standardization (ISO), but standardization of methodology assures neither meaningful results nor appropriate use of the results. This paper examines the types of analysis that are possible for various consumer products, explains possible pitfalls to be avoided, and suggests ways that LCA can be used as part of a rational decision-making procedure. Examples are drawn from studies of municipal waste disposition, using standard methodology. The key to performing a useful analysis is identification of the factors that will actually be used in making the decision. It makes no sense to analyze system energy use in detail if direct financial cost is to be the decision criterion. Criteria may depend on who is making the decision (consumer, producer, regulator). LCA can be used to track system performance for a variety of criteria, including emissions, energy use, and monetary costs, and these can have spatial and temporal distributions. Real decisions are often made using rather narrow criteria; we illustrate how choice of criteria and differences in location can affect decisions. Because optimization of one parameter is likely to worsen another, identification of trade-offs is an important function of LCA. JF - AIR & WASTE MANAGEMENT ASSOCIATION 90. ANNUAL MEETING.

N1 - Last updated - 2011-12-13 ER - TY - BOOK T1 - Enhanced control of mercury emissions through modified speciation AN - 16365659; 4281762 AB - Emissions of mercury from combustion sources continue to receive scrutiny from regulatory agencies at both the state and federal level. Unfortunately, field studies have shown that current flue-gas cleanup systems are relatively ineffective in controlling elemental mercury, which is often a significant component of the total emissions. In particular, typical flue-gas scrubbers give essentially no capture of elemental mercury due to its extremely low solubility. This paper summarizes research at Argonne National Laboratory that has been focused on enhancing the capture of mercury in existing scrubbing systems through conversion of elemental mercury to more soluble mercury compounds. Such a change in speciation can be accomplished through the combination of various chemical agents and native flue-gas components. Initial experiments involved passing a gas containing mercury through bubblers containing dilute solutions of iodine, chlorine, or chloric acid. The extent of conversion (oxidation) was determined by measuring the fraction of inlet mercury that was trapped in the bubbler solutions. In some cases, nitric oxide was found to have a strong beneficial effect on mercury conversion, providing indications that a combined removal process might be feasible. On the other hand, sulfur dioxide generally depressed the conversion, although this effect varied with the chemical agent being used. With these results as a basis, process development research is planned to establish the mercury-control potential of scrubbing with modified speciation under realistic conditions of flue-gas temperature, composition, and residence time.

Phosphates of Mg, Mg-Na, and Zr are being developed as candidate matrix materials. In this paper, we present the fabrication procedures for phosphate waste forms with surrogate compositions of three typical mixed-waste streams, namely ash, cement sludges, and salts. This study was focused, but not limited to, magnesium phosphate-ash wastestream final waste form. The performance of the final waste forms, such as compression strength, leachability of the contaminants, and durability in aqueous environments were conducted. In addition, parametric studies have been conducted to establish the optimal ash waste loading in the magnesium phosphate binder system. Based on the results, we present potential applications of phosphate-bonded ceramics in the treatment of various mixed-waste streams.

ASAPs are based on field analytical methods for rapid sample turnaround and field-based decision support for guiding the progress of the sampling program. One common objective of ASAPs is to delineate contamination present in soils, either to support feasibility studies or remedial action designs. An ASAP based on portable gas chromatograph/ mass spectrograph (GC/MS) technologies developed at Tufts University combined with decision support tools created at Argonne National Laboratory was used to delineate explosives contamination in soils at Joliet Army Ammunition Plant, Joliet, Illinois. Tufts' GC/MS technologies provided contaminant-specific identification and quantification with rapid sample turnaround and high sample throughput. Argonne's decision support tools estimated contamination extent, determined the uncertainty associated with those estimates, and indicated where sampling should continue to minimize uncertainty. In the case of Joliet, per sample analytical costs were reduced by 75 percent as compared to the cost of off-site laboratory analyses for explosives. The use of an ASAP resulted in a much more accurate identification and delineation of contaminated areas than a traditional sampling program would have with the same number of samples collected on a regular grid. While targeting explosives contamination in soils at Joliet, the ASAP technologies used in this demonstration have much broader application.

Modelling was carried out on a bench-scale UASB reactor treating a synthetic brewery waste and which was operated at an organic loading rate of 10 kg COD per m3.d and a hydraulic detention period of 11 h. Tracer studies used a lithium chloride solution that was introduced into the UASB reactor recirculation line, with sodium acetate being used as the modelling substrate.

AN - 78658246; 8989860 AB - The anaerobic degradative pathway for metabolism of 2,4,6-trinitrotoluene (TNT) by a consortium of Desulfovibrio spp. isolated from a creek sediment was studied. This consortium has the metabolic capability to degrade TNT to fatty acids. The growth of the consortium and the metabolism of TNT were greatly enhanced in the presence of an additional carbon source like pyruvate. The optimal concentration of pyruvate for the maximum rate of TNT degradation was 15-20 mM. Various intermediates of TNT metabolism were identified. The first step in the pathway was reduction of TNT to 4-amino-2,6-dinitrotoluene and 2-amino-4,6-dinitrotoluene, which were further reduced to 2,4-diamino,6-nitrotoluene. The next intermediate to appear in the culture medium was nitrobenzoic acid, followed by cyclohexanone, 2-methyl pentanoic acid, butyric acid, and acetic acid. A study using radiolabeled TNT showed that no CO2 was produced from TNT during metabolism. The mass balance of the radiolabeled study showed that 49.6% of the TNT was converted to acetic acid, 28% was assimilated into biomass as trichloroacetic acid precipitable materials, and the rest was distributed as various TNT intermediates. Most Desulfovibrio spp. are incomplete oxidizers that are unable to carry out the terminal oxidation of organic substrates. The major end product of TNT metabolism was acetic acid. The bacteria grew on all the TNT intermediates tested as sole source of carbon, except on acetic acid, confirming that the Desulfovibrio spp. have the enzymes necessary for complete degradation of TNT to acetate.

The acquisition of chemically based images (contrast based on the 1s-1pi (super *) transition of unsaturated carbon), reveals a homogeneous chemical structure in the spore exine. C-NEXAFS microanalysis indicates a chemical structural evolution of the sporopollenin bio/geopolymer with increasing maturation. The most significant change in the C-NEXAFS spectrum is an increase in unsaturated carbon, presumably aromatic, with rank. The rate of "aromatization" in sporinite in coal exceeds that of the associated vitrinite. Increases in the concentration of unsaturated carbon are paralleled by losses of aliphatic and hydroxylated aliphatic carbon components. Carboxyl groups are present in low and variable concentrations. Absorption due to carboxyl persists in the most mature specimen in this series, a high volatile A bituminous coal. The reactions that drive sporopollenin chemical structural evolution during diagenesis presumably involve sequential dehydration, Diels-Alder cyclo-addition, and dehydrogenation reactions that ultimately lead to a progressively aromatized bio/geopolymer.

The results indicate that pyridine transport in this coal proceeds via Case II diffusion for swelling and via Fickian diffusion for deswelling. Once the relative pyridine concentrations reach values between 0.65 and 0.45, the coal's physical state changes from a glassy to a rubbery state. Transitions are well recorded by an inflection observed in the trend of spin-lattice relaxation or spin-spin relaxation of pyridine, as the coal swells and deswells. NMRI data indicate that the coal swelling is anisotropic, with swelling in a plane perpendicular to the coal bedding plane being 13% greater than that parallel to the coal bedding plane; however, the process of deswelling is almost isotropic. The differences between the swelling and deswelling characteristics are discussed from the viewpoint of coal's intrinsic structural properties and stored geologic pressure effects.

Biodegradation of explosives also requires a co-substrate (e.g., molasses), pH>6, and aerobic-anoxic operation. In this study, the native microbial population degraded explosives in soil. Four reactors (350-380 gal) were operated at the Joliet Army Ammunition Plant: a control with no co-substrate, 20% and 10% weekly replacement (by volume) reactors, and a 5% daily replacement reactor. This design allowed investigation of different soil (and therefore TNT 2,4,6-trinitrotoluene) loading rates. The target soil slurry was 15% (weight/weight). Explosives concentrations in soil were 2,000-8,000 mg/kg. Environmental conditions were identical for all reactors, and temperature, pH, and dissolved oxygen were similar. This demonstration showed that the important process parameters for successful (>99%) removal of TNT are an organic co-substrate (molasses), operation in an aerobic-anoxic sequence, and temperature. Cold temperatures slowed the rate of microbial metabolism. The demonstration successfully removed explosives and microbial intermediates from the soil. In summary, the bioslurry system has a real potential to degrade explosives, particularly TNT, from soil.

AN - 78623045; 8968049 AB - Mice bearing the autosomal recessive mutation 'wasted' (wst/wst) express a disease syndrome characterized by neurologic dysfunction, immunodeficiency, and increased sensitivity to the killing effects of ionizing radiation relative to normal littermates (wst/-) and to parental control mice (BCF1, BALB/c, and C57BL/6). Many of these abnormalities, evident as early as 21 days of age, have been localized to thymic tissues and T-lymphocyte populations. Comparison of two-dimensional gel electrophoresis patterns of proteins from wst/wst and control mouse thymus revealed that an acidic protein with a molecular mass of approximately 30 kDa was consistently expressed at lower levels in wasted mice than in controls. Microsequencing of this protein revealed a sequence of 19 N-terminal amino acids identical to the sequence of murine proliferating cell nuclear antigen (PCNA). Northern blot analyses of PCNA expression in thymus and spleen demonstrated lower accumulation of PCNA-specific transcripts in wasted mice compared with that in controls. Because PCNA expression is associated with cell cycle progression, the percentages of thymic and splenic cells in each stage of the cell cycle were examined; there were no differences in the cell stage distribution of lymphocytes freshly isolated from wasted mice compared with littermate or parental controls. After activation with concanavalin A, however, splenocytes from wst/wst mice showed a lower percentage of cells in S phase compared with that in controls. Southern blots with PCNA probes showed that the PCNA loci from the wasted mice and their normal littermates have the same restriction maps. While differences in polymerase chain reaction (PCR) priming were obtained, these could be attributed to strain-specific differences in mouse PCNA pseudogenes. These results suggest the presence of an alteration in the pathway leading to PCNA expression in radiation-sensitive tissues of wasted mice.

AN - 78477562; 8887463 AB - Chronic exposure to cadmium has been linked to bone loss, low bone mass, and increased incidence of fracture. To determine if Cd could directly increase the formation of cells responsible for bone resorption, we cultured normal canine bone marrow cells containing the progenitor cells for osteoclasts. Cultures were evaluated for the number of multinucleate osteoclast-like cells (MNOCs) formed. Exposure to Cd (10-100 nM) increased the number of MNOCs formed over control values when cultured in the presence but not in the absence of a bone wafer. The MNOCs formed were functional, evidenced by pits excavated on the bone wafers included in the cultures. By 12 days, MNOCs formed in the presence of 50 nM Cd excavated significantly more pits and a greater pit area than did untreated MNOCs. By 14 days, the control values were similar to those of the Cd-exposed MNOCs, but pit formation was enhanced by Cd in that the ratio of pit complexes to single pits was increased twofold over that for untreated cultures. Mature osteoclasts, isolated from the long bones of rat neonates and cultured for 1-3 days on bone slices, provided a direct method to assess the effect of Cd on osteoclast activity. Exposure of osteoclast cultures to 100 nM Cd increased the number of osteoclasts present over that for untreated osteoclasts by a factor of 1.7 +/- 0.1, the number of pits excavated by 2.8 +/- 0.6, the area excavated by 3.2 +/- 0.8, and the area excavated per osteoclast by 1.8 +/- 0.4 (mean +/- SE; n = six experiments). These data suggest that Cd accelerates the differentiation of new osteoclasts from their progenitor cells and activates or increases the activity of mature osteoclasts.

The seeps are located approximately 600 ft south of the ANL fence line in Waterfall Glen Forest Preserve. Samples of this water were collected and analyzed for selected parameters. Two of five seeps sampled were found to contain detectable levels of organic contaminants. Three chemical species were identified: chloroform (14-25 mu g/L), carbon tetrachloride (56-340 mu g/L), and tetrachloroethylene (3-6 mu g/L). The other seeps did not contain detectable levels of volatile organic compounds (VOCs). The water issuing from these two contaminated seeps flows into a narrow ravine, where it is visible as a trickle of water flowing through sand and gravel deposits on the floor of the ravine. Approximately 100-ft downstream of the seep area, the contaminated water is no longer visible, having drained back into the soil in the bed of the ravine. Figure 1 shows the location of the 317/319/ENE Area in relation to the ANL-E site and the Waterfall Glen Forest Preserve.

The results of the two refinements confirm the findings of Groat et al. (1992, 1994a, b) on the mechanisms of incorporation of B into the vesuvianite structure. Furthermore, the neutron refinement allowed location of the H, which occurs only at the H(1) position in the crystal examined here. The absence of H at the H(2) channel position, together with the refined scattering at the T(2) site and local bond-valence considerations at the O(10) anion, showed that T(2) is completely occupied by B. The refined site-populations of the O(10) and O(12) sites are compatible only with 0.15 (super [2]) B and 0.85 (super [3]) B at the T(2) site. Other crystals of B-bearing vesuvianite also contain (super [3]) B at T(2) (Groat et al. 1994b). The incorporation of B at T(2) in different coordination environments provides a flexible mechanism that can act in conjunction with other substitutions elsewhere in the structure to satisfy requirements of long-range electroneutrality.

AN - 78222896; 8698571 AB - The goal of this research was to develop a more complete gastrointestinal (GI) tract model for use in internal dose assessment. This paper summarizes the development of a revised mathematical model of the GI tract. The current GI tract model assumes the wall can be represented as a single soft tissue layer without regard to the radiosensitivity of the cells. The goal of the GI tract revision was to develop geometric regions that separate the radiosensitive cells from the less radiosensitive cells. Once the model was revised, it was coded into the Electron Gamma Shower 4 (EGS4) computational package for calculation of photon and electron absorbed fraction values. Photon absorbed fraction values were calculated for twelve discrete energies. For the photon absorbed fraction calculations, the EGS4 program was run so that secondary particles created in photon interactions were followed using the electron tracking capabilities of EGS4. The results of the photon absorbed fraction calculations provided better estimates of the energy deposited in the radiosensitive cells when the target organ was the source. In cases where the target organ was not the source, the photon absorbed fraction values did not provide better estimates than those obtained using the current GI tract model. An increase in the number of photon histories should provide better estimates of the photon absorbed fraction for these cases. Electron absorbed fraction values also were calculated for twelve discrete electron energies. The results of these calculations provided the expected pattern of energy deposition and better estimates than those currently available. The annual limit on intake was recalculated for a single radionuclide to demonstrate the affect of these improved absorbed fraction values on internal dose assessment. The radionuclide was selected for two reasons: 1) it was a beta emitting radionuclide; and 2) the annual limit on intake for ingestion was based on the non-stochastic committed dose equivalent limit to the lower large intestine. The calculated annual limit on intake was found to be three times greater than the annual limit on intake provided in ICRP Publication 30. There are many radionuclides that have a section of the GI tract as the limiting organ for ingestion. It is expected that the annual limit on intake value for these radionuclides would increase when the revised GI tract model is employed for internal dose assessment.

AN - 78218271; 8698570 AB - One goal of this research was to reproduce the photon specific absorbed fraction calculations of Cristy and Eckerman using their gastrointestinal (GI) tract model. A second goal was to calculate photon specific absorbed fraction values for their GI tract model using electron tracking techniques. A final goal was to calculate electron absorbed fraction values for their GI tract model. This paper summarizes the work performed using the currently accepted model of the GI tract provided by Cristy and Eckerman. Their model was coded into the Electron Gamma Shower 4 (EGS4) computational package for calculation of photon specific absorbed fraction values. To benchmark the initial code, the EGS4 program was run so that all secondary particles deposited their energy at the site of the primary photon interaction (i.e., without electron tracking). The results obtained from these preliminary calculations were compared to those provided by Cristy and Eckerman to verify and benchmark the program. Next, specific absorbed fraction values were calculated for twelve discrete photon energies using the electron tracking capabilities of EGS4. These photon specific absorbed fraction values were compared to those calculated without electron tracking. Finally, absorbed fraction values were calculated for twelve discrete electron energies. The electron absorbed fraction values were compared to those calculated without electron tracking. Finally, absorbed fraction values were calculated for twelve discrete electron energies. The electron absorbed fraction values were compared to the ICRP "one-half assumption" for electron energy deposition in the wall of the GI tract.

AN - 78204787; 8697447 AB - Previous work by many groups has documented induction of the human immunodeficiency virus (HIV) long terminal repeat (LTR) following exposure of cells to ultraviolet light and other DNA damaging agents. Our experiments set out to determine the relative activation or repression of the HIV-LTR in response to two classes of chemotherapeutic agents: Doxorubicin is a DNA damage-inducing agent, and 5-fluorouracil has an antimetabolic mode of action. Using HeLa cells stably transfected with a construct in which HIV-LTR drives expression of the chloramphenicol acetyl transferase reporter gene, we demonstrated an up to ten-fold induction following doxorubicin treatment at 24 h post-treatment. This induction was repressed by treatment with salicylic acid, suggesting a role for prostaglandin/cyclo-oxygenase pathways and/or NF-kappa B in the inductive response. Induction by 5-fluorouracil, in contrast, was more modest (two-fold at most) though it was consistently elevated over controls.

AN - 78198901; 8693063 AB - To test the hypothesis that attenuation in G2-phase checkpoint control leads to elevated frequencies of unrejoined chromosome breaks in mitosis, the relationship between G2-phase cell cycle checkpoint control and unrejoined chromosome break frequencies after radiation exposure was examined in cells of 10 human tumor cell lines: 8 squamous cell carcinoma cell lines and 2 lymphoblastoid cell lines. Most of the delay in progression through the cell cycle seen in the first cell cycle after radiation exposure in these cell lines was due to blocks in G2 phase, and there were large cell line-dependent variations in the length of the G2-phase block. There was a highly significant inverse correlation between the length of G2-phase delay after radiation exposure and the frequency of induced unrejoined chromosome breaks seen as chromosome terminal deletions in mitosis. This observation supports the hypothesis that the signal for G2-phase delay in mammalian cells is an unrejoined chromosome break and that attenuation of G2-phase checkpoint control allows cells with unrejoined breaks to progress into mitosis. Attenuation in G2-phase checkpoint control was not associated with alterations in the frequency of induced chromosome rearrangements, suggesting that most chromosome rearrangements develop prior to G2 phase, and there was no significant relationship between the length of G2-phase delay and inherent radiation sensitivity, suggesting that unrejoined chromosome breaks are not the primary toxic lesion induced by radiation in mammalian cells.

The molecular weight of PVA had little effect on the success of hydrothermal hectorite synthesis, d-spacing or the amount of polymer incorporated. The basal spacings range from 19.5 Aa to 20.8 Aa and the amount of polymer incorporated ranges from 20 wt.% to 23 wt.%. Incorporation of PVA within the clay interlayers, along with Li(I) ions to compensate the lattice charge, is indicated. Thermal gravimetric analysis and small angle neutron scattering were used to further examine the polymer-clay systems. Small PVA clay crystallites that are coated with excess PVA are indicated. Removal of the polymer does not alter the extended synthetic clay network, and the nitrogen BET surface area increases from 200 m (super 2) /g.

About 80% of the input of uranium to the lake, with a (super 234) U/ (super 238) U ratio of 2.0, comes from the Selenga River. Profiles of uranium, as well as the extent of isotopic disequilibrium in a 9 m sediment core collected on Academic Ridge, generally show high values during interglacial periods corresponding to high diatom frustule numbers (DiFr) and biogenic silica (BSi) data that have been reported elsewhere. During glacial periods (low DiFr and BSi), uranium progeny ( (super 234) U and (super 230) Th) were in secular equilibrium with low concentrations of their parent (super 238) U. Radionuclide distributions were interpreted in terms of a quantitative model allowing for adsorption of riverine inputs of uranium onto two classes of sedimenting particles with differing (super 238) U/ (super 232) Th ratios and uranium progeny in secular equilibrium. If the (super 234) U/ (super 238) U activity ratio of adsorbed uranium has remained constant, mean sedimentation rates can be independently estimated as 3.6+ or -0.6 and 3.7+ or -0.9 cm.kyr (super -1) for the decay of (super 234) U and in-growth of (super 230) Th, respectively. These rates are consistent with a mean rate of 3.76 cm.kyr (super -1) , calculated by optimization of the correspondence between adsorbed (super 238) U and delta (super 18) O in dated oceanic sediments. The adsorbed uranium apparently tracks variable river flow during interglacials and is drastically reduced during periods of glaciation. Evidently, uranium has not been significantly redistributed within Baikal sediments over at least the past 250 kyr and is a unique, biologically non-essential, tracer for climate-sensitive processes, which provide their own internal geochronometers, potentially useful for ages up to 1 Myr BP.

The number of colony-forming units (CFU) appearing when TNT-contaminated soil was spread on 0.3% molasses plates decreased by 50% when the agar was amended with 67 micrograms TNT/mL, whereas a 99% reduction was observed when uncontaminated soil was plated. Furthermore, TNT-contaminated soil harbored a greater number of organisms able to grow on plates amended with greater than 10 micrograms TNT/mL. Pseudomonas aeruginosa, Pseudomonas corrugate, Pseudomonasfluorescens and Alcaligenes xylosoxidans made up the majority of the gram-negative isolates from TNT-contaminated soil. Gram-positive isolates from both soils demonstrated marked growth inhibition when greater than 8-16 micrograms TNT/mL was present in the culture media. Most pure cultures of known aerobic gram-negative organisms readily degraded TNT and evidenced net consumption of reduced metabolites. The results indicate that gram-negative organisms are most likely responsible for any TNT transformation in contaminated soil, due to their relative insensitivity to high TNT concentrations and their ability to transform TNT.

Volcanic gases collected over five years from Galeras Volcano, Colombia, and analyzed for chemical and isotopic composition show the effects of long-term degassing of the magma body and a gradual decline in sulfur content of the gases. In Contrast, short-term (weeks), sharp variations are the precursors to explosive eruptions. Selective absorption of magmatic SO (sub 2) and HCl due to interaction with low-temperature geothermal waters allows the gas emissions to become dominated by CO (sub 2) . Absorption appears to precede an eruption because magmatic volatiles are slowed or refined by a sealing carapace, reducing the total flux of volatiles and allowing the hydrothermal volatiles to dominate gas emissions. Temporal changes in gas compositions were correlated with eruptive activity and provide new evidence bearing on the mechanism of this type of "pneumatic" explosive eruptions.

The discharge of contaminated groundwater to on-site marshes and adjacent estuaries poses a potential risk to ecological receptors. The Toxic Burning Pits (TBP) area is of special concern because of its disposal history. This report describes a groundwater modeling study conducted at J-Field that focused on the TBP area. The goal of this modeling effort was optimization of the groundwater extraction system at the TBP area by applying linear programming techniques. Initially, the flow field in the J-Field vicinity was characterized with a three-dimensional model that uses existing data and several numerical techniques. A user-specified border was set near the marsh and used as a constraint boundary in two modeled remediation scenarios: containment of the groundwater and containment of groundwater with an impermeable cap installed over the TBP area. In both cases, the objective was to extract the minimum amount of water necessary while satisfying the constraints. The smallest number of wells necessary was then determined for each case. This optimization approach provided two benefits: cost savings, in that the water to be treated and the well installation costs were minimized, and minimization of remediation impacts on the ecology of the marsh.

The site became contaminated with radioactive material as a result of operations conducted by National Lead (NL) Industries from 1958 to 1984; these activities included brass foundry operations, electroplating of metal products, machining of various components using depleted uranium, and limited work with small amounts of enriched uranium and thorium. Residual radioactive material guidelines for individual radionuclides and total uranium were derived on the basis of the requirement that the 50-year committed effective dose equivalent to a hypothetical individual who lives or works in the immediate vicinity of the site should not exceed a dose of 30 mrem/yr following remedial action for the current use and likely future use scenarios or a dose of 100 mrem/yr for less likely future use scenarios. The DOE residual radioactive material guideline computer code, RESRAD, was used in this evaluation; RESRAD implements the methodology described in the DOE manual for establishing residual radioactive material guidelines.

The isolate was unable to use TNT as the sole source of carbon. TNT degradation was accomplished by a co-metabolic process using pyruvate as the main substrate. Two different metabolic steps were employed by this isolate under different electron-accepting conditions. Under sulfate-reducing conditions, TNT was reduced to 4-amino-2,6-dinitrotoluene, 2-amino-4,6-dinitrotoluene and 2,4-diamino-6-nitrotoluene. In contrast, under nitrate-reducing conditions, these amino compounds were not produced, instead, butyric acid was identified as the major metabolite of TNT metabolism. This organism also used a wide variety of other carbon sources, including ethanol, lactate, succinate, formate and malate. The isolate contained the electron-carrier desulfoviridin and used sulfate, nitrate, and thiosulfate as electron acceptors. The isolate had an optimal temperature of 25 degree C and an optimal pH of 6.8 and used ammonium chloride, nitrate and glutamate as nitrogen sources.

Chemical and isotopic data for fluids from wells and fumaroles in Yufuin and Beppu indicate that the thermal activity at Yufuin represents a dilute westward-flowing hydrothermal outflow plume from the Beppu hydrothermal system. Two other (eastward-flowing) outflow plumes have long been recognized at Beppu, but the Yufuin outflow plume is first recognized here. The Yufuin outflow plume is apparently a mixture of two end-member fluids: (1) deep high-temperature (250-300 degrees C) fluid from the Beppu system having high chloride concentration (1400-1600 mg/L) and a delta (super 18) O value near -6.0 per thousand and (2) meteoric water having low chloride concentration (less than or equal to 7 mg/L) and a delta (super 18) O value near -9.2 per thousand. A permeable conduit for the vertical and lateral transport of deep fluid from the Beppu system is provided by the Yufuin Fault zone, which extends westward from the southern flank of Mt. Tsurumi volcano to the town of Yufuin. Stable isotope ratios and chloride concentrations for shallow groundwaters near the eastern end of the fault at an elevation near 700 m are consistent with those required for the low-chloride meteoric end-member of the Yufuin thermal waters. Recharge of this meteoric water, as well as mixing with the Beppu deep fluid may occur along the Yufuin Fault. Enthalpy-chloride relations indicate additional conductive heating of the Yufuin waters in the amount of 350-500 kJ/kg beyond that which can be accounted for by mixing between Beppu deep fluid and meteoric water. This could be a result of conductive heating with convection to a depth of 1 nearly equal 2 km. Estimates of the magnitude of the heat source for the Beppu hydrothermal system should take into account the heat being discharged at Yufuin.

This study was undertaken to aid in the assessment of the amount of remediation needed to reclaim a wetland area. An integrated analysis of electromagnetic, magnetic and ground-penetrating RADAR (GPR) measurements over a 25-acre site, provided the information necessary to define waste disposal events. These events are observed on a sequence of aerial photos taken between 1940 and 1993. The former southwestern embayment of the lake, filled in during the original construction of the base, has been clearly defined. Two burn cages and their surrounding debris have been delineated. The areal extent of another waste site has been defined along the northern shoreline. Depth estimates determined from EM-61 analysis, and depths to original lake bottom, derived from GPR, have yielded volumetric estimates of the amount of material that would need removal if excavation is required. Magnetic and electromagnetic data have pin-pointed the locations of mounds, observed from historical air photos. Except for these areas along the northwestern shore, there is no evidence of waste disposal along the shoreline or within the present-day lake margins. The ability to date the anomalous regions is significant, in that different production demands upon TCAAP, during the time periods of WWII, The Korean War, and The Vietnam Conflict, have resulted in different types of waste. The ability to categorize areas with distinct time periods of operation and waste disposal can greatly aid the environmental cleanup effort with regard to the type of contaminants that might be expected at these poorly documented disposal sites.

Humic substances arise from the decomposition of plant and animal tissues yet are more stable than their precursors. Their size, molecular weight, elemental composition, structure, and the number and position of functional groups vary, depending on the origin and age of the material. Humic and fulvic substances have been studied extensively for more than 200 years; however, much remains unknown regarding their structure and properties. Humic substances are those organic compounds found in the environment that cannot be classified as any other chemical class of compounds. They are traditionally defined according to their solubilities. Fulvic acids are those organic materials that are soluble in water at all pH values. Humic acids are those materials that are insoluble at acidic pH values (pH<2) but are soluble at higher pH values. Humin is the fraction of natural organic materials that is insoluble in water at all pH values. These definitions reflect the traditional methods for separating the different fractions from the original mixture. The humic content of soils varies from 0 to almost 10%. In surface waters, the humic content, expressed as dissolved organic carbon (DOC), varies from 0.1 to 50 ppm in dark-water swamps. In ocean waters, the DOC varies from 0.5 to 1.2 ppm at the surface, and the DOC in samples from deep groundwaters varies from 0.1 to 10 ppm. In addition, about 10% of the DOC in surface waters is found in suspended matter, either as organic or organically coated inorganic particulates. Humic materials function as surfactants, with the ability to bind both hydrophobic and hydrophyllic materials, making numic and fluvic materials effective agents in transporting both organic and inorganic contaminants in the environment.

These residues were designated as corrosive, reactive, toxic, and acute hazardous. The RCRA regulations (40 CFR 260-280), the Utah Administrative Code (R-315), and other state hazardous waste programs list specific wastes as hazardous but allow generators to petition the regulator to "delist" if it can be demonstrated that such wastes are not hazardous. The initial focus is on delisting agent-decontaminated residues and soil with a history of contamination at the U.S. Army Dugway Proving Ground (DPG), Utah. The purpose of this paper is to review the DPG delisting program and discuss overall progress. Emphasis is placed on progress with regard to analytical methods that will be used to demonstrate that the target residues do not contain hazardous amounts of chemical agent.

This site has been designated for remedial action under the Formerly Utilized Sites Remedial Action Program of the US Department of Energy (DOE). Residual radioactive material guidelines for individual radionuclides of concern and total uranium were derived on the basis of the requirement that the 50-year committed effective dose equivalent to a hypothetical individual who lives or works in the immediate vicinity of the New Brunswick Site should not exceed a dose of 30 mrem/yr following remedial action for the current-use and likely future-use scenarios or a dose of 100 mrem/yr for less likely future-use scenarios. The DOE residual radioactive material guideline computer code, RESRAD, was used in this evaluation; RESRAD implements the methodology described in the DOE manual for establishing residual radioactive material guidelines. The guidelines derived in this report are intended to apply to the remediation of these remaining residual radioactive materials at the site. The primary radionuclides of concern in these remaining materials are expected to be radium-226 and, to a lesser extent, natural uranium and thorium. The DOE has established generic cleanup guidelines for radium and thorium in soil; however, cleanup guidelines for other radionuclides must be derived on a site-specific basis.

AN - 78149174; 8721619 AB - The ability of scavengers of hydroxyl radical (OH radical) to modulate the photosensitized relaxation (induction of the first single-strand break) of supercoiled plasmid DNA with UVA photoactivated 4'-aminomethyl-4,5',8-trimethylpsoralen was examined by comparing the dose reduction factor (DRF: the ratio of fluence required to induce the same degree of relaxation in the absence to the presence of OH radical scavengers). The addition of mannitol, azide, acetate, or formate at concentrations inversely proportional to the value of the rate constants for the scavenging of OH radicals partially attenuated the supercoiled DNA relaxation. The degrees of protection afforded by the four scavengers in the presence of AMT photoactivated by either 334 nm or 365 nm monochromatic photons were similar, giving an average DRF of about 0.25 in all cases. Given the diverse chemical nature of the scavengers and their wide range of concentrations utilized, these findings are evidence for the involvement of a Type I photosensitization in the induction of DNA single-strand breaks by photoactivated AMT.

Included are approximately 130 landfill gas samples from across the U.S.A., and 18 recent samples from: (1) an Argonne Laboratory study area in the Brea-Olinda Landfill, Orange County, California (U.S.A); and (2) several Los Angeles County landfills, California (U.S.A). The following isotope ratios were examined: d super(13)C for methane, d super( 13)C for carbon dioxide and dD for methane. Using simple ratio plots supplemented by mass-balance calculations, these data show promise for indicating the relative contributions of the four major carbon cycle processes in landfills, namely: (1) direct oxidation of organic material to carbon dioxide; (2) methane generation from fermentation (acetate cleavage); (3) methane generation from carbon dioxide reduction; and (4) methane oxidation to carbon dioxide by methanotrophic bacteria. Both the methane generation and oxidation reactions are central to an explanation of the trends discussed herein. The data also suggest that direct oxidation of organic matter in the refuse may be contributing to the observed isotopic ratios in some cases. The trends observed at the Brea-Olinda site were similar to trends using the large U.S. database, suggesting that isotopic techniques may be useful to better constrain carbon cycle processes common to all landfill settings.

Near the top of the landfill, small soil gas pressure differences with respect to atmospheric pressure have been typically disregarded but may be important to considerations of gas flux into and out of landfill cover materials. The authors have developed a portable, inexpensive system using off-the-shelf components to sensitively monitor pressures, temperatures and meteorological variables on a continuous basis. Previous experience has indicated that continuous monitoring of pressure changes is necessary to understand the dynamics of convection in the shallow subsurface.This application relies on a distributed network of commercially available Z-180 microprocessor-based integrated controllers to condition signals from electronic pressure transducers, meteorological sensors, and various temperature-sensing devices : thermocouples, thermistors and resistance temperature detectors (RTDs). Output is recorded continuously over an Appletalk+ network. The sensitivity of the authors' current system exceeds 4 Pa for pressure and 0.01C for temperature (thermistor sensors).This paper will describe the basic system components. The various choices for both temperature and pressure sensors will be discussed with respect to their sensitivity, adaptability and resolution. In addition, sample data output will be presented to illustrate the dynamics of shallow subsurface pressure and temperature changes.

These changes alter atmospheric circulation patterns, shifting the location of wet and dry climate zones. As a region shifts from dry to wet, clastic sediment yield can vary by as much as two orders of magnitude. Particular phases of regional climate changes are not correlative; some regions become wetter as others become drier. Therefore, regional sediment yield cycles may not be synchronous. Glacioeustatic cycles, primarily a function of the insolation cycle in the glaciated hemisphere, are globally synchronous. As a result, there is no set phase relationship between glacioeustasy and regional sediment yield. Additionally, northern and southern hemisphere insolation cycles, ordinarily 180 degrees out of phase, can become nearly in phase as eccentricity approaches zero. We examined potential inter-hemispheric variability under conditions of a southern polar glacier. Accommodation space was assumed to be a function of sea level, with sediment yield a function of climate. Insolation values at different latitudes for a 5 million year interval were calculated, with the insolation cycle for the 60o S used as a proxy indicator of sea level. Sediment supply was calculated as a function of the summer insolation at a given latitude. This simple model produced markedly different patterns of stratigraphic bed thickness for the two hemispheres, suggesting the style of variability to look for in the stratigraphic record.

This study identifies the preferred transport routes of a dissolved dense nonaqueous phase liquid (DNAPL) plume under a site located at the mouth of the Gunpowder river which discharges into Chesapeake Bay. The site is in a highland surrounded by marshes on three sides within a peninsula.Analysis of soil borings indicates that the sediment deposition was primarily affected by three factors: the sediment supply by the river adjacent to the site, the tidal action in the bay, and the sea level fluctuation of the Pleistocene. The physical characteristics of the sediment vary spatially, ranging from silty very fine- to medium-grained sand. The lateral variation of the grain size reflects the various facies of sedimentation, like that of a barrier island in a bay environment. The vertical variation reflects the last phase of sea level uprising of the Pleistocene, resulting in the transgressive sequential nature of the sediment. The high ground of the site is a groundwater recharge area and was also the source area of DNAPL contaminants. Groundwater samples, collected from monitoring wells on land and in the marsh, and surface water samples, collected in the marsh, indicate that a dissolved DNAPL plume exists in the aquifer. The preferred transport routes of the contaminants followed southern and southeastern trends, migrating under the marsh and also emerging locally at the edge of the highland as seepage. The preferred routes are indicated by the relatively high concentration levels of contaminants in groundwater and in local surface water. The pattern of the transport routes is consistent with the spatial distribution of medium-grained sand deposited in the bay-side of the barrier island.

The latter encompasses over 90% of the agricultural land of Egypt. Satellite data were used to monitor the encroachment of urbanization onto the Nile Delta throughout the past three decades and to direct efforts to combat them. The Delta is covered by three Multi-spectral Scanner (MSS) scenes and four Landsat Thematic Mapper (TM) scenes. A mosaic was generated from three MSS scenes acquired over the Delta in August and September of 1972. Another was generated from TM scenes acquired over the Delta in September of 1984 and a third was generated from TM images acquired in May and August of 1990. The three satellite mosaics were co- registered and the images were processed to enhance spectral variations between cultivated land and urban areas and to minimize spectral variations related to atmospheric interferences and differences in sun angle elevation. Three color composites were generated from pairs of the three digital mosaics, and were used to identify the location and timing of urban progression in the Nile Delta. Preliminary results indicate that Egypt has lost at least 10% of its agricultural land to urbanization throughout the past thirty years, and that expansion of the smaller, yet numerous, villages poses the largest threat to Egypt's agricultural land.

Such conditions also describe decomposition of refuse in sanitary landfills and provide a reasonable model for systematic studies of their long-term geochemistry. For shorter time frame (decades), controlled high-solids anaerobic digestion systems provide a second model for investigation of optimized landfill systems. In this paper, we introduce both models through a series of preliminary mass-balances to develop a realistic overview of landfill processes, especially emphasizing carbon cycling in field settings over various time-frames. The terminal product of short-term anaerobic decomposition is methane--produced by methanogenic bacteria from some fraction of organic carbon landfilled. Laboratory studies of optimized landfill systems (ours and from the literature) indicate that, at best, 25-45% of organic carbon is converted to biogas carbon (methane and carbon dioxide); such percentages are rarely attained in field settings. Most of the methane is produced from cellulosic substrates while lignin substrates are recalcitrant, with lignin carbon entering sedimentary storage for time frames longer than the four decades of widespread landfilling experience in the U.S. and western Europe. Over time frames in excess of centuries, further transformations via kerogen pathways are possible but highly speculative. Certainly, exhumation of old refuse at archeologic sites indicates that organic carbon preservation can be documented for at least one or two millenia. From controlled incubation of unamended field samples and from field studies of net methane emissions, it is clear that rates of methane production and consumption both vary of several orders of magnitude in field settings; their dynamic are rapid and complex spatially and temporally. Unraveling these dynamics is necessary to suggest the overall relevance of these engineered anoxic basins to issues of atmospheric methane increases and terrestrial carbon storage.

Carbonates in the upper 200 ft of the Ogallala Formation (below the Caprock Caliche layer at the top of the formation) have average (n = 16) d13C (PDB) and d18O (SMOW) values of -5.2 per mil and 24.7 per mil, respectively. In the Blackwater Draw Formation, carbonates collected from near the surface to the bottom of the formation (above the Caprock Caliche) have average (n = 34) d13C and d18O values of -1.0 and 25.4 per mil, respectively. The isotopic values are nearly uniform with depth in both the formations. The d18O values indicate a lack of significant warming towards the end of the Ogallala deposition and precipitation from soil solutions that were not impacted by evaporation. The lower d13C values of paleosols in the Ogallala indicate that soil gas carbon dioxide was derived from mixed C3-C4 vegetation, compared to primarily C4 vegetation in the Blackwater Draw. Vegetation utilizing the C4 photosynthetic mechanism is considered to have evolved in semiarid and subtropical areas in the late Miocene and to have expanded rapidly between about 7-5 Ma, due to a decrease in the atmospheric carbon dioxide levels (Cerling et al., Nature, 1993). Isotopic compositions of paleosols from the southern High Plains provide evidence for this global ecological change.

A plot dominated by crown vetch (Coronilla varia) and bluegrass (Poa spp.), exhibited a constant decrease in emissions of total non-methane organic compounds (NMOCs) from 580 micrograms/sq m/hr in June 1992 to 150 micrograms/sq m/hr in October 1992, except for a slight increase in August. Total NMOC emission rates based on vegetative biomass averaged 2.3 micrograms/g/hr, with 10% of the identified NMOCs attributed to monoterpenes and the remainder mainly OxHCs. Over the course of the investigation, the relationship between the monoterpene emission rate and the temperature for a single plot was logarithmic and similar to the one between compound vapor pressure and temperature. However, emission rates normalized to temperature decreased throughout the summer and fall, indicating that parameterizations of emission rates from herbaceous plants must include a factor to compensate for environmental conditions such as soil moisture and nutrient deposition, which affect plant phenology and the seasonal pattern of species dominance.

Gamma-ray spectra from resulting neutron reactions inside the inspected volume identify fissionable materials and many nuclides. Flight times from detection times of the gamma rays and alpha particles separate the prompt and delayed gamma-ray spectra and can yield coarse tomographic images from a single orientation. The high-energy neutrons and gamma rays penetrate large objects and dense materials. The gamma-ray detector and neutron generator can be on the same side of the interrogated objects, so walls and other confined areas can be inspected as well as sealed containers. No collimators or radiation shielding are needed. The neutron generator is simple and small. Commercial electronics are used. A complete system could be transported in a van. Laboratory and limited field tests indicate APSTNG could be useful in analyzing radioactive waste in drums, walls, soils, and processing systems, particularly for unknown or heterogeneous configurations that may attenuate radiation. Toxic chemicals could be identified in mixed waste, and the ability to detect pockets of water may address criticality concerns.

The EG&G Mound Applied Technologies site in Miamisburg, Ohio, has an estimated 1.5 million cubic feet of soils from past disposal and waste burial practices awaiting remediation from plutonium contamination. This amount includes sediment from the Miami-Erie Canal that was contaminated in 1969 following a pipe-rupture accident. Conventional soil washing techniques that use particle separation would generate too large a waste volume to be economically feasible. Therefore, innovative technologies are needed for the cleanup. The ACT*DE*CON process was developed by SELENTEC for washing soils to selectively dissolve and remove heavy metals and radionuclides. ACT*DE*CON chemically dissolves and removes heavy metals and radionuclides from soils and sediments into an aqueous medium.

The stability constant beta for the PuO (sub 2) H (sub 2) PO (sub 4) (super +) species was determined to be log beta = 0.1+ or -0.1 (ionic strength = 0.6-0.9 M) and log beta (super T) = 2.6+ or -0.15 (zero ionic strength). Four Pu(VI)-phosphate species (absorption bands at 842, 846, 857, and 866 nm) formed at pH = 2.4 to 12.2 and are characterized by polynuclear behavior, the formation of precipitates, and colloidal properties. The 842 and 846 nm species are believed to be PuO (sub 2) (HPO (sub 4) ) (sub mn) and PuO (sub 2) (NaPO (sub 4) ) (sub mn) . The 857 and 866 nm species area as yet unidentified. The speciation of plutonium with phosphate is of interest to radionuclide migration studies because phosphate is present in many groundwaters and may be used as an actinide getter in nuclear waste disposal. An actinide getter is a complexing agent that forms insoluble phases with actinides, thereby reducing their migration.

The goal was to investigate changes in the community structure of soil fauna in study sites receiving different amounts of acidic deposition for several decades and the possible relationships between these changes and physico-chemical properties of soil. The study revealed significant differences in the numbers of soil animals among the three study sites. The sharply differentiated pattern of soil macroinvertebrate fauna seems closely linked to soil chemistry. Significant correlations of the abundance of soil macroinvertebrates with soil parameters suggest that their populations could have been affected by acidic deposition in the region. Abundance of total soil macroinvertebrates decreased with the increased cumulative loading of acidic deposition. Among the groups most sensitive to deposition were: earthworms gastropods, dipteran larvae, termites, and predatory beetles. The results of the study support the hypothesis that chronic long-term acidic deposition could aversely affect the soil decomposer community which could cause lower organic matter turnover rates leading to an increase in soil organic matter content in high deposition sites.

The treatment technologies for the "No-Flame" option differ from previous LLMW technologies analyzed in the WM PEIS in that the incineration and thermal desorption technologies are replaced by sludge washing, soil washing, debris washing, and organic destruction. A set of dominant waste treatment processes and accident scenarios were selected for analysis by means of a screening process. A subset of results (release source terms) from this analysis is presented. JF - Accident analysis for the low-level mixed waste "no-flame" option in the U. S.

The chemical agents of concern include levinstein mustard, lewisite, sarin, and VX. This investigation has been initially divided into three phases: (1) a literature search to determine what, if any, previous studies have been conducted; (2) a technologies-screening critique of remedial technologies as alternatives to incineration; and (3) an investigation of promising alternatives on RMA soil at the laboratory and bench-scale levels. This paper summarizes the document produced as a result of the technologies screening. The purpose of the document was to determine the applicability of 25 technologies to remediation of agent-contaminated soil for a general site. Technologies were critiqued on the basis of applicability to soil type, applicability to the agents of concern at RMA, applicability to other types of contaminants, cost of the treatment, current status of the technology, and residuals produced.

AN - 52577023; 1998-051153 AB - An unusual convex-upward REE trend is found in acidic waters draining granitic terranes throughout the world. This trend has implications for the weathering behavior of REEs in acidic environments but its source is not yet fully understood. Bog seep and mine effluent waters in the Paradise Basin area of the San Juan Mountains, Colorado, display this pattern. Using cathodoluminescence spectrography and electron microprobe analysis, our study determined that the main REE concentrating minerals present in the bedrock (the San Juan Tuff and two quartz monzonite stocks) are apatite, zircon, and epidote. These minerals account for all of the measured IREEs (Sm, Dy) and HREEs (Yb) in the rocks. Most of the LREEs (La, Ce, Pr, Nd) are located elsewhere in the rock and most likely are present in sericite, chlorite, submicroscopic monazite, and/or in a submicroscopic La-Ce phosphate mineral. The electron-probed apatite from the tuff displays a convex-upward REE pattern while the epidote and zircon display a consistently increasing pattern from La to Yb. Of the apatite, epidote, and zircon, apatite displays the most intense weathering. Mass balance calculations indicate that weathering of 0.3 grams of apatite per liter of fluid is sufficient to produce the REE concentration seen in both the bog seep and mine effluent waters. Our study concludes that the convex-upward REE trend observed in these waters is the result of selective weathering of apatite, which itself displays a distinctive convex-upward REE pattern, and the retention of LREEs in secondary phases such as clays, sericite, chlorite, etc. JF - Abstracts with Programs - Geological Society of America AU - Bundy, Maria E AU - Oreskes, Naomi AU - Hanchar, John M AU - Anonymous Y1 - 1996 PY - 1996 DA - 1996 SP - 469 PB - Geological Society of America (GSA), Boulder, CO VL - 28 IS - 7 SN - 0016-7592, 0016-7592 KW - United States KW - Paradise Basin KW - igneous rocks KW - granites KW - seepage KW - electron probe data KW - Cenozoic KW - plutonic rocks KW - mineral composition KW - mass balance KW - rare earths KW - water KW - apatite KW - North America KW - effluents KW - U.

In many cases, attempts to degrade nitroaromatics under aerobic conditions by pure cultures result in no mineralization and only superficial modifications of the structure. However, mixed culture systems properly operated result in the transformation of 2,4,6-trinitrotoluene (TNT) and in some cases mineralization of TNT occurs. In this paper, the mixed culture system is described with emphasis on intermediates and the characteristics of the aerobic microbial process including the necessity for a co-substrate. The possibility of removing TNT under aerobic/anoxic conditions is described in detail. Another option for the biodegradation of TNT and nitroaromatics is under anaerobic, sulfate reducing conditions. In this instance, the nitroaromatic compounds undergo a series of reductions with the formation of amino compounds. TNT under sulfate reducing conditions is reduced to triaminotoluene presumably by the enzyme nitrite reductase, which is commonly found in many Desulfovibrio spp. The removal of nitro groups from TNT is achieved by a series of reductive reactions with the formation of ammonia and toluene by Desulfovibrio sp. (B strain). These metabolic processes could be applied to other nitroaromatic compounds like nitrobenzene, nitrobenzoic acids, nitrophenols, and aniline. The data supporting the anaerobic transformation of TNT under different growth condition are reviewed in this report.

Results will be presented from three sets of these drip tests: two with actinide-doped glasses, and one with a fully-radioactive glass. Periodic sampling of these tests have revealed trends in actinide release behavior that are consistent with their entrainment in colloidal material when as-cast glass is reacted. Results from vapor hydrated glass show that initially the actinides are completely dissolved in solution, but as the reaction proceeds, the actinides become suspended in solution. Sequential filtering and alpha spectroscopy of colloid-bearing leachate solutions indicate that more than 80 percent of the plutonium and americium are bound to particles that are captured by a 0. 1 gm filter, while less than 10 percent of the neptunium is stopped by a 0. 1 gm filter. Analytical transmission electron microscopy has been used to examine particles from leachate solutions and to identify several actinide-bearing phases which are responsible for the majority of actinide release during glass corrosion.

Glass dissolution rates were calculated from measured B concentrations in tests conducted for up to five years. The dissolution rates of all glasses increased significantly after certain alteration phases precipitated. Calculation of the dissolution rates was complicated by the decrease in the available surface area as the glass dissolves. We took the loss of surface area into account by modeling the particles to be spheres, then extracting from the short-term test results the dissolution rate corresponding to a linear decrease in the radius of spherical particles. The measured extent of dissolution in tests conducted for longer times was less than predicted with this linear dissolution model. This indicates that advanced stages of corrosion are affected by another process besides dissolution, which we believe to be associated with a decrease in the precipitation rate of the alteration phases. These results show that the dissolution rate measured soon after the formation of certain alteration phases provides an upper limit for the long-term dissolution rate, and can be used to determine a bounding value for the source term for radionuclide release from waste glasses. The long-term dissolution rates measured in tests at 20,000 per mil at 90 degrees C in tuff groundwater at pH values near 12 for the Environmental Assessment glass and glasses made with SRL 131 and SRL 202 frits, respectively.

Net flux densities were measured at heights 5 and 10 m above an agricultural field with short corn plants and large amount of exposed bare soil between the rows. Large upward eddy fluxes of NO (sub 2) were seen, and strong NO emissions from the soil were measured by collaborators using environmental enclosures on the soil surface. Data indicate that about 50% of the nitrogen emitted from the soil as NO was converted into NO (sub 2) at 5 m. Rest of the emitted nitrogen may remain as NO flux and be returned back to the vegetation and soil by deposition. Divergence of the NO (sub 2) and O (sub 3) fluxes were detected between 5 and 10 m.

An understanding of glass reaction and the manner by which radionuclides are released is needed to design the waste package and to evaluate the total performance of the repository. The ASTM Standard C-1174-91 provides a general methodology for obtaining information related to the behavior of glass. This paper reviews the application of this standard to glass reaction. In the first step in the ASTM approach, the researcher identifies the materials and the conditions under which the long-term behavior is to be determined. Glass compositions have undergone a genesis over the past 15 years in response to concerns about feed streams, processing, and durability. A range of borosilicate compositions has been identified, but as new applications for vitrification occur, for example, immobilization of weapons plutonium and residue from plutonium processing, different compositions must be evaluated. The repository environment depends on the spatial emplacement of waste containers (glass and spent fuel), and both "hot" and "cold" scenarios have been proposed for the Yucca Mountain site. Regardless of the exact configuration, the near-field hydrology is expected to be unsaturated: that is, the waste packages are contacted initially by water vapor, and ultimately by small amounts of dripping or standing water. The behavior of glass can be studied as a function of composition within the constraints the environmental conditions place on the physical parameters that affect glass reaction (temperature, radiation field, groundwater composition, etc.). In the second step, the researcher reviews the literature and proposes a reaction pathway by which glass reacts in an unsaturated environment.

Current research at Argonne National Laboratory includes a successful field demonstration of a plant bioreactor for processing the salty wastewater from petroleum wells; the demonstration is currently under way at a natural gas well site in Oklahoma, in cooperation with Devon Energy Corporation. A greenhouse experiment on zinc uptake in hybrid poplar (Populus sp.) was initiated in 1995. These experiments are being conducted to confirm and extend field data from Applied Natural Sciences, Inc. (our CRADA partner), indicating high levels of zinc (4,200 ppm) in leaves of hybrid poplar growing as a cleanup system at a site with zinc contamination in the root zone of some of the trees. Analyses of soil water from experimental pots that had received several doses of zinc indicated that the zinc was totally sequestered by the plants in about 4 hours during a single pass through the root system. The data also showed concentrations of sequestered metal of >38,000 ppm Zn in the dry root tissue. These levels of sequestered zinc exceed the levels found in either roots or tops of many of the known "hyperaccumulator" species. Because the roots sequester most of the contaminant taken up in most plants, a major objective of this program is to determine the feasibility of root harvesting as a method to maximize the removal of contaminants from soils. Available techniques and equipment for harvesting plant roots, including young tree roots, are being evaluated and modified as necessary for use with phytoremediation plants.

The neglect of colloidal properties in assessing the near- and far-field migration behavior of actinides may lead to significant underestimates and poor predictions of biosphere exposure from high-level waste (HLW) disposal. Existing data on colloid-facilitated transport suggests that radionuclide migration may be enhanced, but the importance of colloids is not adequately assessed. Indeed, the occurrence of radionuclide transport, attributed to colloidal species, has been reported at Mortandad Canyon, Los Alamos and at the Nevada Test Site; both unsaturated regions are similar to the proposed HLW repository at Yucca Mountain. Although some developments have been made on understanding the transport characteristics of colloids, the characterization of colloids generated from the corrosion of the waste form has been limited. Colloids are known to incorporate radionuclides either from hydrolysis of dissolved species (real colloids) or from adsorption of dissolved species onto existing groundwater colloids (pseudocolloids); however, these colloids may be considered secondary and solubility limited when compared to the colloids generated during glass alteration.

The objective of this project was to develop and test the efficacy of a comprehensive methodology for assessing ecological impacts of soil contamination. A hierarchical approach that integrates biotic parameters and ecosystem processes was used to give insight into the mechanisms that lead to alterations in the structure and function of soil ecosystems in contaminated areas. This approach involved (1) a thorough survey of the soil biota to determine community structure, (2) laboratory and field tests on critical ecosystem processes, (3) toxicity trials, and (4) the use of spatial analyses to provide input to the decision-making process. This methodology appears to offer an efficient and potentially cost-saving tool for remedial investigations of contaminated sites. JF - NATO Science Series.

Our research includes a successful field demonstration of a plant bioreactor for processing the salty wastewater from petroleum wells; the demonstration is currently under way at a natural gas well site in Oklahoma, in cooperation with Devon Energy Corporation. A greenhouse experiment on zinc uptake in hybrid poplar (Populus sp.) was initiated in 1995. These experiments are being conducted to confirm and extend field data indicating high levels of zinc (4,200 ppm) in leaves of hybrid poplar growing as a cleanup system at a site with zinc contamination in the root zone of some of the trees. Analyses of soil water from experimental pots that had received several doses of zinc indicated that the zinc was totally sequestered by the plants in about 4 hours during a single pass through the root system. The data also showed concentrations of sequestered metal of >38,000 ppm Zn in the dry root tissue. These levels of sequestered zinc exceed the levels found in either roots or tops of many of the known "hyperaccumulator" species. Because the roots sequester most of the contaminant taken up in most plants, a major objective of this program is to determine the feasibility of root harvesting as a method to maximize the removal of contaminants from soils. Available techniques and equipment for harvesting plant roots, including young tree roots, are being evaluated and modified as necessary for use with phytoremediation plants.

With this system, contaminated groundwater can be funneled into a treatment system without pumping the contaminated water to the surface. The EnviroWall (super TM) barrier and pass-through system, an innovative product of six years of research and development, provides a means to enhance groundwater flow on the upgradient side of an impermeable wall and direct it to an in situ treatment system. The EnviroWall (super TM) system is adaptable to most site conditions. Remedial applications range form plume containment to more robust designs that incorporate groundwater manipulation coupled with in situ treatment. Several key innovations of the EnviroWall (super TM) system include the following: a method for guide box installation; a means for using interlocking seals at vertical seams; a down-hole video camera for inspecting seams and panels, installation of horizontal- and vertical-collection systems; installation of vertical monitoring wells and instrumentation on each side of the barrier; site-specific backfill design; and a pass-through system for funneling groundwater into a treatment system.

A detailed introduction to the MAGPIE system architecture AN - 20350231; 7574736 AB - A system called MAGPIE (Multipurpose Automated Genome Project Investigation Environment) has been designed and implemented to meet the challenges of automated whole genome analysis. The system initiates large numbers of remote and local transactions, each depending on evolving criteria and on changing remote and local conditions. Transactions are requested from different types of remote and local resources. The remote request load is fairly balanced with other community demands on server resources. Local decision modules monitor and obey user preferences and combine evidence from multiple sources to formulate credible hypotheses about sequence function. Consistency checks from multiple types of data are integrated into the ongoing local analysis. The system performs reliably on local UNIX workstations and communicates with remote resources through standard networking protocols.

Many of the features of this mouse model have suggested a premature or increased spontaneous frequency of apoptosis in thymocytes. Past work has documented an inability to establish cultured T cell lines, an abnormally high death rate of stimulated T cells in culture, and an increased sensitivity of T cells to the killing effects of ionizing radiations in the wst/wst mouse relative to controls. The experiments reported here were designed to examine splenic and thymic lymphocytes from the wasted and control mouse for signs of early apoptosis. Our results revealed enhanced expression of Rp-8 mRNA (which has been associated with apoptosis) in thymic lymphocytes and to a lesser extent in spinal cord in the wst/wst mouse relative to controls; expression of Rp-2 and Tcl-30 mRNA (also reported to be induced during apoptosis) were not detectable in spleen or thymus. Expression of Rp-2, Rp-8, and Tcl-30 mRNA in other affected tissues of the wasted mouse (brain and liver) were similar in the wasted mouse and controls. Thymus and spleen from the wasted mouse have reduced numbers of viable cells relative to controls. Higher spontaneous DNA fragmentation was observed in lymphocytes from the wasted mouse than in controls; however, gamma -ray-induced DNA fragmentation peaked at a lower dose and occurred to a greater extent in lymphocytes derived from the wasted mouse relative to controls. These results suggest that high spontaneous and gamma -ray-induced apoptosis in T cells of the wasted mouse may contribute to the mechanism underlying the observed lymphocyte and DNA repair abnormalities.

Sequence analysis of the Pf gene indicated an open reading frame specifying a protein of 485 amino acids (aa) with a calculated Mr of 52900. Canonical Archaea promoter elements, Box A and Box B, are located -49 and -17 nucleotides (nt), respectively, upstream of the putative start codon. The sequence of the putative active-site region conforms to the IMPDH signature motif and contains a putative active-site cysteine. Phylogenetic relationships derived by using all available IMPDH sequences are consistent with trees developed for other molecules; they do not precisely resolve the history of Pf IMPDH but indicate a close similarity to bacterial IMPDH proteins. The phylogenetic analysis indicates that a gene duplication occurred prior to the division between rodents and humans, accounting for the Type I and II isoforms identified in mice and humans.

Often, a lack of basic information on the chemical and physical characteristics of the soil and contaminants hampers treatability studies used to design these technologies. This article proposes and demonstrates a characterization program to meet these information needs, employing standard analytical techniques coupled with advanced spectroscopy and microscopy techniques. To support treatments involving physical separation strategies, the program uses standard analytical techniques to characterize the soil and the association of contaminants with different soil fractions (e.g., size and density fractions). Where chemical treatments are required, spectroscopy and microscopy methods are employed to yield quantitative information on the oxidation state and speciation of the contaminant. Examples demonstrate the use of measured soil and contaminant characteristics in the screening of alternative treatment technologies and in the selection of soils for use in treatability studies. Also demonstrated is the use of these characterization tools in the design and optimization of treatment strategies and in support of risk assessment determinations.

The separation module concentrated the sample by a factor of 30 and removed the potential for interference by the environmental matrix. Detection was accomplished using inductively-coupled plasma mass spectrometry. Uranium-238 was determined in groundwater with a detection limit of 0.30 ng per litre. A precision of 1.1 per cent and an accuracy of 1.8 per cent were obtained for uranium-238 present at a concentration of 62.6 ng per litre.

They are: limiting the thermal mixing zone to 305 m, and removing the option for regulatory agencies to establish less stringent thermal limits if the discharger could demonstrate no deleterious effects. Surveys were carried out at a selection of power plants to ascertain the implications. The usual response was to retrofit cooling towers and, in some cases, diffusers at an estimated capital cost of 21.4-24.4 billion U.S. dollars. There was a 1-5.8 per cent energy penalty, implying operating costs of 10-18.4 billion U.S. dollars in 20 years and the production of 7.3 billion kg per year of additional carbon dioxide. Extra evaporation of 94.5 m3 per second would also occur. Neither amendment was adopted but re-introduction was possible in a future Congress.

This method has been used to identify spatial heterogeneity of geologic structures and to estimate spatial scales of geophysical parameters in the subsurface. We used the integral wavelet transform to analyze the spatial variability of permeability in the alluvial fan deposits in Radioactive Waste Management Site Area 5 of Nevada. The mother wavelet which we used is the "Mexican Hat" function. A wavelet variance is defined to detect the characteristic scales of non-periodically spaced spatial structures. Results showed heterogeneity of spatial structure in permeability at hierarchical scales and difference of scales between transects in spatially distributed permeability. These multiscale features of spatial variability of permeability provide an explanation for the strong quasi-periodic behavior in the horizontal and vertical semivariograms. A comparison among wavelets, fractals, and traditional geostatistics is also given. Copyright 1995 by the American Geophysical Union.

The results show that the distribution of alkylxylene isomers in a low maturity crude oil is similar to that obtained from the clay catalyzed methylation of ortho-alkyltoluene, a common naturally occurring alkyltoluene isomer. The distribution patterns of more mature crude oils are replicated experimentally by allowing the initially formned alkylxylenes to isomerize further. Methylation reaction is mainly responsible for the formation of alkylxylenes in sediments. Clay catalysis is important in the isomerization of alkyltoluenes and alkylxylenes.

The correlation approach of Langmuir & Riese for predicting empirical distribution coefficients is improved when a term for the elastic strain energy is included for when the Ca atom is replaced by the larger Ra atom. This simplified elastic analysis shows that the strain energy for this substitution is comparable to the difference in the free energies of dissolution of the corresponding Ra and Ca compounds. Distribution coefficients can be estimated and applied in geochemical equilibrium models to account for Ra incorporation into sulphates, carbonates and halides for Ra-containing radwaste.

AN - 77704776; 7586189 AB - The effects of cycloheximide (CHX) and 2-[(aminopropyl)-amino]ethanethiol (WR-1065), each alone or in combination, on radiation-induced mutation induction at the hypoxanthine-guanine phosphoribosyl transferase (hprt) locus and cell killing were investigated using a Chinese hamster ovary (CHO) AA8 cell system. Treatment with CHX, a potent inhibitor of protein synthesis, at a concentration of 10 micrograms/ml administered 30 min prior to irradiation with 7.5 Gy had no effect on cell survival but did reduce the radiation-induced mutation frequency (per 10(6) survivors) from 106.5 +/- 8.8 (SEM) to 36.2 +/- 5.6 (SEM). Exposure of cells to 4 mM WR-1065 reduced the mutation frequency to 44.8 +/- 4.2 (SEM), but the combination of agents afforded no additional protection, that is 41.1 +/- 3.3 (SEM). The mechanism of action attributed to CHX in reducing mutation frequency is its ability to prevent the induction of an error-prone repair system. Split-dose radiation experiments, that is 8 Gy versus 4 Gy + 4 Gy separated by 3 h, were performed to evaluate and contrast the relative abilities of CHX and WR-1065, each alone or in combination, in affecting cell survival. Cycloheximide administered to cells 30 min before the first radiation dose and present throughout the 3 h incubation time prior to the second dose inhibited split-dose repair as evidence by a reduction in surviving fraction by 60% as compared with the value obtained for non-CHX-treated cells that were exposed to two equal doses of 4 Gy. Cells exposed to 4 mM WR-1065 immediately following the first 4 Gy radiation dose and then washed free 2.5 h before exposure to a second Gy dose, which was also followed by a 30 min exposure to WR-1065, increased the surviving fraction by 80% over the value obtained for cells not exposed to WR-1065 during their split-dose radiation treatment. When CHX treatment was combined with WR-1065 was abolished, that is surviving cell fraction was again reduced by approximately 60% as compared with untreated control groups. These results indicate that protein synthesis is required for WR-1065 to affect split-dose related repair processes. Presumably, the inhibition of the induction of an error-phone repair system by CHX would account for its effects on both resultant decreases in mutation frequency and cell survival. In contrast, WR-1065 and/or its disulfide metabolite appear to facilitate the efficacy and fidelity of such a repair system once it is induced.(ABSTRACT TRUNCATED AT 400 WORDS) JF - Carcinogenesis AU - Murley, J S AU - Grdina, D J AD - Center for Mechanistic Biology and Biotechnology, Argonne National Laboratory, IL 60439-4833, USA.

AN - 77631690; 7585506 AB - Previous studies have shown that the radioprotector WR1065 protects against mutagenesis across a wide concentration range (i.e., 40 microM to 4 mM) but protects against cell killing by ionizing radiation at concentrations greater than 1 mM. Other work has demonstrated that many genes are induced or repressed after exposure of cells in culture to ionizing radiation, but the actual inducing agents for this gene modulation response are unknown. In these experiments, we set out to identify genes that would be modulated in response to two different concentrations of WR1065 (i.e., a lower dose that is incapable of protecting against cell killing but effective in protecting against mutation induction, and a high dose that is effective in protecting against both end points). Using differential display reverse transcription-PCR, we compared genes expressed in untreated cells to those expressed in cells treated with different concentrations of WR1065 (4 mM or 40 microM) with or without radiation exposure (7.5 Gy). One band, which showed a differential response, was sequenced and found to have homology in the 3'-untranslated region of the mouse thymidine kinase (tk) gene but not identity to the Chinese hamster ovary tk gene. Dot blot and Northern blot analyses confirmed the differential display results and also determined that regulation of the tk-like gene is similar to that of tk itself. These experiments established that in Chinese hamster ovary cells, radiation causes a repression in accumulation of tk mRNA and a related tk-like transcript. This repression is made less dramatic by the presence of 40 microM WR1065, and, in fact, expression becomes enhanced when cells are pretreated with 4 mM WR1065.

These studies indicate that during the Pleistocene Epoch, alternating stands of high and low sea levels resulted in a complex pattern of shallow channel-fill deposits around the Bush River Peninsula. Ground-penetrating radar studies reveal paleochannels greater than 50 ft deep. This paleochannel depositional system is environmentally significant because it may control the shallow groundwater flow regime beneath the peninsula. Magnetic, conductivity, and side-scan sonar anomalies outline anthropogenic anomalies in the study area.

Because of the low solubilities of plutonium and uranium, and the low ground water velocities, the analysis shows that such a scenario with (super 239) Pu is probably impossible because the time required to accumulate a critical mass is large compared with the half-life of the (super 239) Pu. In the case of (super 235) U, the analysis indicates that the accumulation rates are so low that relatively small fission power levels would consume the (super 235) U as fast as it accumulates, and that the thermal conductivity of the tuff is large enough to prevent a significant increase in temperature. Thus, the conditions for the removal of water by boiling and the associated autocatalytic increase in reactivity are not met in the case of (super 235) U. An explosive release of energy does not appear to be possible. A simple water voiding model, which allows water removal at about the fastest possible rate, was used to explore a scenario in which the fuel accumulation rate was arbitrarily increased enough to cause water boiling and the associated dryout of the tuff. Calculations for this case indicate that disruption of the tuff, leading to a neutronic shutdown, would probably occur before an explosive energy release could be generated. Additional scenarios, which should be investigated in future work are identified.

AN - 77567430; 7563066 AB - A site-specific double mutant, in which the large aromatic residues M208Tyr and L181Phe in the interior of the photosynthetic reaction center (RC) complex were replaced by smaller threonine residues, showed a dramatic reduction in the number of assembled complexes and was incapable of photosynthetic growth. The cavity created by the smaller side-chains was thought to interfere with the stability and/or assembly of the complex. Phenotypic revertants were recovered in which a spontaneous second-site mutation restored photocompetence in the presence of the original site-specific mutations. In these strains, an Ala-->Pro substitution in a neighboring transmembrane helix (at M271) resulted in an increased yield of RC complexes. To test the hypothesis that the original phenotype was due to a cavity, other mutants were constructed that created similar-sized voids at other positions in the membrane-spanning interior. These substitutions caused the same phenotype. Coupling of the above proline substitution to these new cavity mutants also resulted in photocompetent strains that carry increased levels of RC complexes. Therefore, the proline substitution at M271 serves as a global suppressor of the phenotype caused by these internal cavities. The proline substitution slightly increases the thermal stability of the complex at higher temperatures, but the mutant and suppressor strains have about the same stability at the optimal culture temperature, where both are less stable than the wild-type strain. Therefore, the proline substitution may suppress the non-photosynthetic phenotype of cavity mutants by facilitating folding of the nascent polypeptides as they assemble with cofactors to form the transmembranar RC complex. The proline replacement occurs at a pre-existing kink in a transmembrane helix where it can be accommodated without introducing a strain in the structure. The function of proline residues in transmembrane helices might be to promote folding and/or assembly in general.

AN - 77442051; 7635728 AB - Alpha-particle spectrograms of bone samples from USTUR Case 246 were analyzed to determine the depth in tissue from which the 241Am alpha-particles were emitted. In four samples of bone, the lack of energy straggling in the alpha spectra indicated that essentially all the 241Am was deposited directly on the exposed bone surface, and none had been translocated to within bone volume. These findings agree well with the results of autoradiographic examination of bone samples from the same case, but are in marked contrast to findings on another case (USTUR Case 102) who had been exposed to a much smaller amount of 241Am at a younger age and survived approximately twice as long after the exposure. It is problematical whether the lack of 241Am redistribution, and therefore the implied absence of bone remodeling, in Case 246 was due to his advanced age at exposure or to a deterministic effect of alpha-irradiation on bone metabolism, but the observation of radiation effects on bone metabolism in former radium workers supports the latter.

Examined here is the demographic evolution of this island group, exploring changes in the number of inhabitants & their geographic distribution. First, the foreign presence in the eastern Carolines & the demographic impacts of these outsiders are summarized. Shifts in the regional arrangement of population are then described, focusing on data from censuses conducted 1920-1989. Data on fertility, mortality, & migration provide insights on possible causes of pouplation change. The application of selected spatial statistics in the geographic arrangement of population indicates a high degree of consistency in the distribution of people & the persistence of geographic subregions over time.

AN - 77484588; 7658472 AB - Cholera toxin, a heterohexameric AB5 enterotoxin released by Vibrio cholera, induces a profuse secretory diarrhea in susceptible hosts. Choleragenoid, the B subunit pentamer of cholera toxin, directs the enzymatic A subunit to its target by binding the GM1 gangliosides exposed on the luminal surface of intestinal epithelial cells. The crystal structure of choleragenoid has been independently solved and refined at 2.4 A resolution by combining single isomorphous replacement with non-crystallographic symmetry averaging. The structure of the B subunits, and their pentameric arrangement, closely resembles that reported for the intact holotoxin, choleragen, the heat-labile enterotoxin from Escherichia coli, and for a choleragenoid-GM1 pentasaccharide complex. In the absence of the A subunit the central cavity of the B pentamer is a highly solvated channel. The binding of choleragenoid to the A subunit or to its receptor pentasaccharide modestly affects the local stereochemistry without perceptibly altering the subunit interface.

AN - 77478353; 7658473 AB - The clinical manifestations of cholera are largely attributable to the actions of a secreted hexameric AB5 enterotoxin (choleragen). We have independently solved and refined the three-dimensional structure of choleragen at 2.5 A resolution. The structure of the crystalline toxin closely resembles that described for the heat-labile enterotoxin from Escherichia coli (LT) with which it shares 80% sequence homology. In both cases, the wedge-shaped A subunit is loosely held high above the plane of the pentameric B subunits by the tethering A2 chain. The most striking difference between the two toxins occurs at the carboxyl terminus of the A2 chain. Whereas the last 14 residues of the A2 chain of LT threading through the central pore of the B5 assembly form an extended chain with a terminal loop, the A2 chain of choleragen remains a nearly continuous alpha-helix throughout its length. The four carboxyl-terminal residues of the A2 chain (KDEL sequence), disordered in the crystal structure of LT, are clearly visible in choleragen's electron-density map. In the accompanying article we describe the three-dimensional structure of the isolated B pentamer of cholera toxin (choleragenoid). Comparison of the crystalline coordinates of choleragen, choleragenoid, and LT provides a solid three-dimensional foundation for further experimental investigation. These structures, along with those of related toxins from Shigella dysenteria and Bordetella pertussis, offer a first step towards the rational design of new vaccines and anti-microbial agents.

Anomalous areas noted in the geophysical data sets have been correlated with features visible in a chronological sequence of aerial photos. The photos aid in dating the anthropogenic changes and in interpreting the geophysical anomalies observed at Site H and across Sunfish Lake. Specifically, two burn cages and what has been interpreted as their surrounding debris have been delineated. The areal extent of another waste site has been defined in the southwest corner of Area H-1. Depth estimates to the top of the Area H-1 anomalies show that the anomalies lie below lake level, indicative of dumping directly into Sunfish Lake. Except for these areas along the northwestern shore, there is no evidence of waste disposal along the shoreline or within the present-day lake margins. Magnetic, electromagnetic, and ground-penetrating-radar data have pinpointed the locations of mounds, observable in aerial photos, around the first burn cage. The second burn cage and its surrounding area have also been clearly defined from aerial photos, with support from further geophysical data. Additional analysis of the data has yielded volumetric estimates of the amount of material that would need removal in the event of excavation of the anomalous areas. Magnetic and electromagnetic profiles were also run across Marsden Lake. On the basis of these data, it has been concluded that no large-scale dumping has occurred in or around Marsden Lake.

Data were gathered from a content analysis of the New York Times to determine coverage, from various Gallup Poll surveys to determine public agenda issues, & from publications of Environmental Quality & the Characterization of Municipal Solid Waste in the United States to determine real world pollution conditions. Analysis reveals that, though the frequency of reports decreased, the length & prominence of articles increased. Further, despite an overall decrease in the level of real world pollution, media coverage increased. It is concluded that agenda setting played a key role in the public focus on environmental decay during the period. 2 Tables, 7 Figures. Adapted from the source document.

The ABE process is best suited to the recovery of ultrafine, refractory material from the silt and clay fractions of soils. During continuous countercurrent extraction tests with soil samples from the Fernald Environmental Management Project site (Fernald, OH), particulate thorium was extracted and concentrated between 6- and 16-fold, while the uranium concentration was reduced from about 500 mg/kg to about 77 mg/kg. Preliminary estimates for treatment costs are approximately $160 per ton of dry soil. A detailed flowsheet of the ABE process is provided.

AN - 77373070; 7600523 AB - Experiments were designed to examine the effects of radiation dose-rate and cycloheximide on expression of cytoskeletal and matrix elements in Syrian hamster embryo cells. Results here demonstrated little effect of dose-rate for fission-spectrum neutrons when comparing expression of alpha-tubulin or fibronectin genes. Effects of cycloheximide, however, revealed several findings: (a) Cycloheximide repressed accumulation of alpha-tubulin following exposure to high dose-rate neutrons or gamma-rays. (b) Cycloheximide did not affect accumulation of mRNA for actin genes. (c) Cycloheximide abrogated the moderate induction of fibronectin-mRNA which occurred following exposure to gamma-rays and high dose-rate neutrons.

AN - 77485572; 7655090 AB - Uranium-contaminated soils from the U.S. Department of Energy (DOE) Fernald Site, Ohio, have been examined by a combination of backscattered electron imaging (BSE) and analytical electron microscopy with electron diffraction (AEM). The inhomogeneous distribution of particulate uranium phases in the soil required the development of a method for using ultramicrotomy to prepare transmission electron microscopy (TEM) thin sections from the SEM mounts. A water-miscible resin was selected that allowed comparison between SEM and TEM images, permitting representative sampling of the soil. Uranium was found in iron oxides, silicates (soddyite), phosphates (autunites), and uraninite (UO2 + x). No uranium was detected in association with phyllosilicates in the soil.

AN - 77500000; 7666775 AB - The gamma-ray sensitivity of two human lymphoblastoid cell lines, TK6 and WI-L2-NS, was studied; both cell lines are derived from the same parent, WI-L2. TK6 was more sensitive to the cytotoxic effects of gamma rays, but showed fewer induced chromosome aberrations. There was no difference between the two cell lines in their capacity to rejoin DNA double-strand breaks or in the kinetics of the rejoining process. The kinetics of cell cycle progression following radiation exposure was also similar in TK6 and WI-L2-NS. However, while TK6 cells were very sensitive to apoptosis induction, showing high levels of apoptotic cells within 24 h of exposure, no evidence for any significant levels of apoptosis was found for WI-L2-NS within 30 h of irradiation, when chromosome aberration frequency was determined. Evidence of apotosis were seen at later times in WI-L2-NS cells, but the levels were significantly lower than comparably treated TK6 cells. The results support a hypothesis that the lower survival and induced aberration frequencies in TK6 cells are due to selective removal of damaged cells by apoptotic processes prior to analysis of chromosome aberration frequencies in mitosis.

AN - 77324835; 7770511 AB - Action spectra (365-520 nm) for the formation of DNA single-strand breaks (SSB) and slowly developing alkali-labile sites (SDALS) in human teratocarcinoma P3 cells in culture were determined. Induction of SDALS results from the absorption of blue- and green-light photons. The spectrum has a broad peak that is maximal between 400 nm to 500 nm and declines sharply above and below these wavelength regions. Negligible yields of SDALS were produced by photons at wavelengths of 365 nm or shorter and at 520 nm or longer, whereas for SSB, the action ioffeases with shorter wavelength throughout the whole spectral range studied. The configuration of the SDALS action spectrum suggests that the primary chromophore, and therefore possibly the photosensitizer, is a mixture of porphyrin and flavin residues.

AN - 77224724; 7724734 AB - We investigated the role of reactive oxygen intermediates and protein kinase C in the induction of expression of the c-jun gene in human ML-2 leukemic cells and normal human DET-551 fibroblasts by comparing the effects of exposure to either ionizing radiation or H2O2 in the presence or absence of appropriate inhibitors. In these cell types, the radiation- and H2O2-mediated increase in c-jun mRNA levels could be prevented by pretreatment of the cells with N-acetylcysteine, an antioxidant, or H7, an inhibitor of protein kinase C and protein kinase A, but not by HA1004, a specific inhibitor of protein kinase A and G. These results suggest a role for protein kinase C and reactive oxygen intermediates in the induction of c-jun gene expression in both normal and tumor cells. We also investigated potential differences in c-jun gene expression induced by radiation or H2O2 in normal and tumor cells by examining steady-state c-jun mRNA levels in a number of human fibroblast, leukemia, melanoma, sarcoma and carcinoma cell types. We observed heterogeneity in the steady-state level of c-jun mRNA in both the untreated normal and tumor cells and in such cells exposed to ionizing radiation or to H2O2. Exposure to radiation produced a varied response which ranged from little or no induction to an increase in the steady-state level of the c-jun mRNA of more than two orders of magnitude. Exposure to H2O2 gave a pattern similar to that of ionizing radiation. The basis for the differential induction in response to these agents may be attributable to either cell lineage or genetic heterogeneity or a combination of these two parameters.

The surveillance program is the ongoing remedial action that resulted from the 1976-1978 radiological characterization of the site. That study determined that very low levels of hydrogen-3 (as tritiated water) had migrated from the burial ground and were present in two nearby hand-pumped picnic wells. The current program consists of sample collection and analysis of air, surface and subsurface water, and bottom sediment. The results of the analyses are used to (1) monitor the migration pathway of water from the burial ground (Plot M) to the hand-pumped picnic wells, (2) establish if buried radionuclides other than hydrogen-3 have migrated, and (3) generally characterize the radiological environment of the area. Hydrogen-3 in the Red Gate Woods picnic wells was still detected this year, but the average and maximum concentrations were significantly less than found earlier. Tritiated water continues to be detected in a number of wells, boreholes, dolomite holes, and a surface stream. For many years, it was the only radionuclide found to have migrated in measurable quantities. Analyses since 1984 have indicated the presence of low levels of strontium-90 in water from a number of boreholes next to Plot M. The available data does not allow a firm conclusion as to whether the presence of this nuclide represents recent migration or movement that may have occurred before Plot M was capped. The results of the surveillance program continue to indicate that the radioactivity remaining at Site A/Plot M does not endanger the health or safety of the public visiting the site, using the picnic area, or living in the vicinity.

Ultrasonic vacuum extraction provides near-quantitative gas yields within 30 min, and allows on-line preparation of carbon dioxide, nitrogen and oxygen for isotopic analyses. This method eliminates uncertainties involved in correcting headspace gas analyses for solubilities and liquid-vapor isotopic fractionation. In addition to developmental data, some field results are given to demonstrate the applicability of the method to geochemical studies.

AN - 77216314; 7712477 AB - Previous studies have shown that exposure of HeLa cells stably transfected with an HIV-long terminal repeat-chloramphenicol acetyltransferase (HIV-LTR-CAT) construct to many DNA-damaging agents (such as UV light) induces expression from the HIV LTR. By culturing the cells with salicylic acid we demonstrated dose-dependent repression of this UV-or cis-platinum (cis-Pt)-induced HIV expression. While salicylic acid treatment, indomethacin treatment, UV exposure, or cis-Pt treatment alone decreased viability by up to 50%, equal numbers of viable cells were used for the CAT assays. Repression was evident if salicylic acid was administered 2 h before, at the same time as, or up to 6 h after exposure to the DNA-damaging agent. The kinetics were similar for UV- and for cis-Pt-induced HIV expression, and induction was dependent on the UV dose or cis-Pt concentration added to the culture. pH changes of the media alone in the absence of salicylic acid did not affect HIV expression. Indomethacin (100 microM) did not affect UV- or cis-Pt-induced HIV expression. These results suggest a role for the prostaglandins or the cyclo-oxygenase pathway or both in HIV induction mediated by DNA-damaging agents.

AN - 77230017; 7728953 AB - The ability of the potential chemopreventive agent S-2-(3-aminopropylamino)ethylphosphorothioic acid (WR-2721) to protect against radiation-induced mutagenesis at the hprt locus and cell killing was studied using CHO-AA8 cells incubated for 30 min at 37 degrees C in growth medium containing its active thiol 2-[(aminopropyl)amino]ethane-thiol (WR-1065). In parallel experiments, the thiol and disulfide forms of the drug present in cells and incubation medium were determined in order to identify which, if either, of the components were associated with the observed protective effects. Treatment with 4 mM WR-1065 produced significant intracellular levels of the thiol (WRSH) and disulfide (WRSS) forms of the drug, but also caused dramatic elevation of cellular glutathione (GSH) and cysteine levels, accompanied by marked protection against 60Co gamma-photon- and neutron-induced cell killing and mutagenesis. When drug-treated cells were transferred to drug-free medium and incubated for 4 h at 37 degrees C, levels of WRSH and WRSS and protection against cell killing decreased markedly, whereas levels of GSH and cysteine and protection against mutagenesis showed little change. GSH and cysteine levels were not associated with protection against radiation-induced mutagenesis, as established by experiments performed with buthionine sulfoximine to block GSH synthesis. These data do not support the hypothesis that modulation of GSH or cysteine levels by WR-1065 is a major mechanism accounting for protection. Protection against mutagenesis was seen for cells incubated in medium with concentrations of added WR-1065 as low as 10 microM, where cellular levels of WRSH and WRSS became difficult to measure (< or = 5 microM) and no protection against cell killing was found. An unexpected observation was that cells incubated in 40 microM WR-1065 incorporated the drug much more rapidly than expected for uptake by passive diffusion and concentrated the drug to a marked degree; this indicates that a cell-mediated transport system is involved in the uptake of WR-1065 at low drug concentrations.

This site has been identified for remedial action under the U.S. Department of Energy's (DOE's) Formerly Utilized Sites Remedial Action Program (FUSRAP). Single-nuclide and total-uranium guidelines were derived on the basis of the requirement that following remedial action, the 50-year committed effective dose equivalent to a hypothetical individual living or working in the immediate vicinity of the site should not exceed a dose constraint of 30 mrem/yr for the current use and likely future use scenarios or a dose limit of 100 mrem/yr for less likely future use scenarios. The DOE residual radioactive material guideline computer code, RESRAD, was used in this evaluation; RESRAD implements the methodology described in the DOE manual for establishing residual radioactive material guidelines. Three scenarios were considered; each assumed that for a period of 1,000 years following remedial action, the site would be used without radiological restrictions. The three scenarios varied with regard to the type of site use, time spent at the site by the exposed individual, and sources of food and water consumed. The evaluation indicates that the dose constraint of 30 mrem/yr would not be exceeded for uranium (including uranium-234, uranium-235, and uranium-238) within 1,000 years, provided that the soil concentration of total combined uranium (uranium-234, uranium-235, and uranium-238) at the former Baker Brothers site did not exceed 710 pCi/g for Scenario A (industrial worker, current use) or 210 pCi/g for Scenario B (resident - municipal water supply, a likely future use). The dose limit of 100 mrem/yr would not be exceeded at the site if the total uranium concentration of the soil did not exceed 500 pCi/g for Scenario C (subsistence farmer - on-site well water, a plausible but unlikely future use).

An alternative to leaching is microwave digestion. In the past. microwave technology has had limited application in the radiochemical laboratory because of restrictions on sample size resulting from vessel pressure limitations. However, new microwave vessel designs allow for pressures on the order of 11 MPa (1500 psi). A procedure is described in which microwave digestion is used to prepare environmental soil samples for gross alpha/beta analysis. Results indicate that the described procedure meets performance requirements for several soil types and is equivalent to traditional digestion techniques. No statistical differences at the 95% confidence interval exist between the measurement on samples prepared from the hot plate and microwave digestion procedures for those soils tested. Moreover, microwave digestion allows samples to be prepared in a fraction of the time with significantly less acid and with lower potential of cross-contamination. In comparison to the traditional hot plate method, the waste volumes required for the microwave procedure are a factor of 10 lower, while the analyst time for sample processing is at least a factor of three lower.

These residues are listed as hazardous waste in Utah and several other States, but are not listed under regulations established by the US Environmental Protection Agency (EPA) pursuant to the Federal Resource Conservation and Recovery Act (RCRA), the primary law governing management of hazardous waste in the US. These residues are identified as hazardous waste due to corrosivity, reactivity, chronic toxicity, and acute toxicity, and are designated as Hazardous Waste No. F999. The RCRA regulations (40 CFR 260-280), the Utah Administrative Code (R-315), and other State hazardous waste programs list specific wastes as hazardous, but allow generators to petition the regulator to "delist" if it can be demonstrated that such wastes are not hazardous. The US Army Test and Evaluation Command (TECOM) has initiated a project with the Argonne National Laboratory to demonstrate that certain categories of F999 residues are not hazardous waste and to achieve delisting. The initial focus is on delisting specific residues from decontamination of wastes generated during materials testing activities and contaminated soil at the US Army Dugway Proving Ground (DPG), Utah. This activity is referred to as Phase I of the delisting program. Subsequent phases of the delisting program will address additional waste streams at DPG and other Army installations. The purpose of this paper is to outline the Phase I TECOM delisting effort at DPG, identify some of the important technical issues associated with the delisting, and to discuss overall progress to date.

Soil and plant samples were collected from the Group 61 area at the Joliet Army Ammunition Plant and analyzed to determine the extent to which 2,4,6-trinitrotoluene (TNT) and its degradation products are taken up by existing vegetation and crops growing on contaminated soils. Neither TNT nor its degradation products was detected in any of the above ground plant organs of existing vegetation. Oat (Avena sativa L.) and perennial rye grass (Lolium perenne L.) were planted on TNT-contaminated soils amended with three levels of chopped grass hay. Extractable TNT concentrations in hay-amended soils were monitored for almost 1 year. Crop establishment and growth improved with increased levels of hay amendment, but TNT uptake was not affected or detected in any above ground crop organs. Evidence was found to indicate that soil manipulation and hay addition may reduce extractable TNT concentration in soils, but the wide variations in TNT concentrations in these soils prevented development of conclusive evidence regarding reduction of extractable TNT concentrations. Results from this study suggest that vegetation grown on TNT-contaminated soils is not a major health concern because TNT and its degradation products were not detected in above ground plant organs. However, low concentrations of TNT, 4-amino-2,6-dinitrotoluene, and 2-amino-4,6-dinitrotoluene were detected in or on some existing vegetation and crop roots.

Porewater salinity is calculated from electrical measurements, including resistivity soundings, electric logs, and electromagnetic profiling. Electrical measurements support the primary, basin-wide groundwater flow model; however, the data also indicate secondary contributions from expulsion of fluids under geopressure along active growth faults and from original waters of deposition. Expulsion of water from growth faults has been described previously for deeper sections of the Pleistocene, but has not been reported for the Holocene or upper Pleistocene beneath the Louisiana wetlands. Porewater chemistry variations beneath the coastal wetlands are a consequence of the following (in order of importance): (1) environment of deposition; (2) a basin-wide, regional flow system; (3) expulsion from deep-seated growth faults; and (4) pore water extrusion due to compaction. Water chemistry in Holocene clays and muds is influenced primarily by the deposition environment. In Pleistocene sands, the chemistry is a function of the other three factors.

The cross-well data (obtained from a variable-frequency, cross-well seismic experiment using source frequencies of 1, 3, 5, and 7 kHz) were augmented with velocities derived from a nearby seismic refraction station using a low-frequency (<20 Hz) source. Velocities obtained from the borehole-sonic tool (18 kHz) were not used, because it is unclear at this time what signal phase was being detected. Energy at 1 and 3 kHz was successfully transmitted over distances from 3.69 to 30 m; the 5- and 7-kHz data were obtained only at distances up to 20 m. Velocity tomograms were constructed for one borehole pair and covered a depth interval of 10-50 m. Results from the tomographic modeling indicate that gas-induced low velocities are present to depths of greater than 40 m. Analysis of the velocity dispersion suggests that gas-bubble resonance must be greater than 7 kHz, which is above the range of frequencies used in the experiment. Washout of the boreholes at depths above 15 m resulted in a degassed zone containing velocities higher than those indicated in both nearby refraction and reflection surveys. Velocity and attenuation information were obtained for a low-velocity zone centered at a depth of approximately 18 m. Measured attenuations of 1.57, 2.95, and 3.24 dB/m for the 3-, 5-, and 7-kHz signals, respectively, were modeled along with the velocity data using a silt-clay sediment type. Density and porosity data for the model were obtained from the geophysical logs; the bulk and shear moduli were estimated from published relationships. Modeling results indicate that gas bubbles measuring 1 mm in diameter occupy at least 25% to 35% of the pore space.

AN - 50146039; 1995-039869 AB - Laminated to thin-bedded siltstones directly overlie Carboniferous coals at several localities in the Eastern Interior Coal Basin. Because lamina thicknesses show cyclical variations, the siltstones have been termed "tidal rhythmites". The rhythmites commonly show a repetitive thick-thin pairing of the laminae, and these two-lamina rhythmites have been interpreted as the result of the asymmetry of flood and ebb velocities that affected sedimentation in a diurnal paleotidal system. Alternatively, the pairing has been interpreted to be related to a pronounced difference in height between successive high tides in a semidiurnal system. This explanation suggests deposition in a mixed, predominately semidiurnal system with a marked diurnal inequality. In addition to the two-lamina rhythmites described originally, subsequent examination of drill cores indicates the occurrence of relatively rare, more complex three- and four-lamina rhythmites. A variety of mathematical techniques are used herein to analyze lamina thickness data extracted from these rhythmites. Processing techniques include: (1) comparing the linear relationship between the thicknesses of the thinner and thicker laminae and comparing these relationships to modern tidal systems; (2) analyses of thickness periodicities and comparison with modern neap-spring tidal cycles; and (3) extraction of lamina thickness inequalities and comparison to the diurnal inequalities that occur in semidiurnal tidal systems. These tests indicate that reasonable conclusions can be made for the type of originating paleotidal system. For the cases analyzed herein, the paleotidal signature suggests a mixed, predominantly semidiurnal system with a marked diurnal inequality.

The information gained from these studies has been used in the development and testing of remediation technologies. Most chemical washing techniques have been reasonably effective with uranyl (U(VI)) phases, but U(IV) phases have proven difficult to remove from the soils. Carbonate leaching in an oxygen environment (heap leaching) has removed some of the U(IV) phases, and it appears to be the most effective technique developed in the program. The uranium metaphosphate, which was found exclusively at an incinerator site, has not been removed by any of the chemical methods. We suggest that a physical extraction procedure (either a magnetic separation or aqueous biphasic process) be used to remove this phase. Analytical electron microscopy has also been used to determine the effect of the chemical agents on the uranium phases. It has also been used to examine soils from the Portsmouth site in Ohio. The contamination there took the form of uranium oxide and uranium calcium oxide phases. Technology transfer efforts over FY 1994 have led to industry-sponsored projects involving soil characterization.

J-Field is within the Edgewood Area of APG in Harford County, Maryland. Since World War II, activities in the Edgewood Area have included the development, manufacture, testing, and destruction of chemical agents and munitions. These materials were destroyed at J-Field by open burning and open detonation (OB/OD). Considerable archival information about J-Field exists as a result of efforts by APG staff to characterize the hazards associated with the site. Contamination of J-Field was first detected during an environmental survey of the Edgewood Area conducted in 1977 and 1978 by the US Army Toxic and Hazardous Materials Agency (USATHAMA) (predecessor to the US Army Environmental Center). As part of a subsequent USATHAMA environmental survey, 11 wells were installed and sampled at J-Field. Contamination at J-Field was also detected during a munitions disposal survey conducted by Princeton Aqua Science in 1983. The Princeton Aqua Science investigation involved the installation and sampling of nine wells and the collection and analysis of surficial and deep composite soil samples. In 1986, a Resource Conservation and Recovery Act (RCRA) permit (MD3-21-0021355) requiring a basewide RCRA Facility Assessment (RFA) and a hydrogeologic assessment of J-Field was issued by the US Environmental Protection Agency (EPA). In 1987, the US Geological Survey (USGS) began a two-phased hydrogeologic assessment in which data were collected to model groundwater flow at J-Field. Soil gas investigations were conducted, several well clusters were installed, a groundwater flow model was developed, and groundwater and surface water monitoring programs were established that continue today.

From 1988 through 1992, numerous laboratory- and bench-scale indirect-heated thermal desorption (IHTD) treatability studies have been performed on various soil medium groups from the arsenal. RMA has contracted Argonne National Laboratory to conduct a pilot-scale direct-fired thermal desorption (DFTD) treatability study on pesticide-contaminated RMA soil. The purpose of this treatability study is to evaluate the overall effectiveness of the DFTD technology on contaminated RMA soils and to provide data upon which future conceptual design assumptions and cost estimates for a full-scale system can be made. The equipment used in the DFTD treatability study is of large enough scale to provide good full-scale design parameters and operating conditions. The study will also provide valuable-emissions and materials-handling data. Specifically this program will determine if DFTD can achieve reductions in soil contamination below the RMA preliminary remediation goals (PRGs), define system operating conditions for achieving the PRGs, and determine the fate of arsenic and other hazardous metals at these operating conditions. This paper intends to compare existing data from a bench-scale IHTD treatability study using equipment operated in the batch mode to new data from a pilot-scale DFTD operated in a parallel-flow continuous mode. Delays due to materials-handling problems and permit issues have delayed the start of the pilot-scale DFTD testing. The first pilot-scale test is scheduled for the flat week in January 1995. The available data will be presented March 9, 1995, at the Seventh Annual Gulf Coast Environmental Conference in Houston, Texas.

This also includes evaluations for the effects of Natural Phenomena Hazards (NPH), for which these facilities may not have been designed. The NPH evaluations follow the requirements of DOE Order 5480.28, Natural Phenomena Hazards Mitigation (1993) which establishes NPH Performance Categories (PCs) for DOE facilities and associated target probabilistic performance goals. These goals are expressed as the mean annual probability of exceedance of acceptable behavior for structures, systems and components (SSCs) subjected to NPH effects. The assignment of an NPH Performance Category is based on the overall hazard categorization (low, moderate, high) of a facility and on the function of an SSC under evaluation (DOE-STD-1021, 1992). Detailed guidance for the NPH analysis and evaluation criteria are also provided (DOE-STD-1020, 1994). These analyses can be very resource intensive, and may not be necessary for the evaluation of all SSCs in existing facilities, in particular for low hazard category facilities. An approach relying heavily on screening inspections, engineering judgment and use of NPH experience data (S. J. Eder et al., 1993), can minimize the analytical effort, give reasonable estimates of the NPH susceptibilities, and yield adequate information for an overall safety evaluation of the facility. In the following sections this approach is described in more detail and is illustrated by an application to a nuclear laboratory complex.

Studies have been performed to evaluate the performance of nuclear waste glass and spent fuel samples under unsaturated conditions (low volume water contact) that are likely to exist in the Yucca Mountain environment being considered as a potential site for a high-level waste repository. Tests with simulated waste glasses have been in progress for over eight years and demonstrate that actinides from initially fresh glass surfaces will be released as a result of the spallation of reacted glass layers from the surface, as the small volume of water passes over the waste form. Studies are also underway to evaluate the performance of spent fuel samples and unirradiated UO(sub 2) in projected repository conditions. Tests with UO(sub 2) have been ongoing for nine years and show that the oxidation of UO(sub 2) occurs rapidly, and the resulting paragenetic sequence of secondary phases that form on the sample surface is similar to that observed in natural analogues. The reaction of spent fuel samples under conditions similar to those used with UO(sub 2) have been in progress for nearly two years, and the results suggest that spent fuel follows the same reaction progress as UO(sub 2). The release of individual fission products and transuranic elements was not congruent, with the release being controlled by the formation of small particles or colloids that are suspended in solution and transported away from the waste form. The reaction progress depends on the composition of the spent fuel samples used and, likely, on the composition of the groundwater that contacts the waste form.

AN - 77136400; 7852813 AB - Production of DNA damage by exposure to ionizing radiation was measured in two in vitro systems. A supercoiled plasmid of 7.3 kbp was isolated and exposed in an aqueous environment to 60Co gamma rays and JANUS 0.85 MeV fission-spectrum neutrons. Dose responses for the production of single-strand breaks (ssbs) and double-strand breaks (dsbs) were computed from the conversion of the supercoil to its relaxed and linear forms. The relative effectiveness (neutrons:gamma-rays) for destruction of genetic transforming activity of M13 viral DNA was 0.23, close to that for ssb production, in contrast with the situation for biological effects such as lethality, mutagenesis and cellular transformation measured in mammalian cells, where RBEs are > 1. The role of hydroxyl (OH) radicals in DNA damage induction by neutrons was investigated by exposure of plasmid in the presence of known quenchers of this species. Of four quenchers tested, all were able to reduce the yields of both ssbs and dsbs.

Included were: (1) a potassium sulphate extraction technique with quantification of organic carbon for measurement of microbial biomass; and (2) an arginine ammonification technique for microbial activity. Four profiles consisting of replaced soils were sampled for this study; units included topsoil (mixed mollisol A and B horizons), compacted clay cover (local calcareous Wisconsinan age glacial till), and mixed soil/refuse samples. Internally consistent results across the four profiles and good correlations with other independent indicators of microbial activity (moisture, organic matter content, nitrogen, and phosphorus) suggest that, even though these techniques were developed mainly for natural mineral soils, they are also applicable to disturbed landfill soils.

Ultratrace determination of curium, with the ability to quantify the fraction that is curium-242, provides a signature method of detecting clandestine reprocessing of recently irradiated uranium targets. Curium initially present in any of a variety of materials such as air filters, solid or liquid process waste, soil, flora, or fauna can be recovered via current chemical separations processing techniques. Using the ultratrace method being developed, such recovered curium will be quantified with thousand-fold higher sensitivity than the best currently available method which is alpha counting.

By examining Fernald samples that had undergone chemical leaching it was possible to observe the effect the treatment had on specific uranium-bearing phases. The technique of Heap leaching, using carbonate solution, was found to be the most successful in removing uranium from Fernald soils, the Heap process allows aeration, which facilitates the oxidation of uraninite. However, another refractory uranium(IV) phase, uranium metaphosphate, was not removed or affected by any soil-washing process. Examination of "hot particles" from Johnston Island revealed that plutonium and uranium were present in 50-200 nm particles, both amorphous and crystalline, within a partially amorphous aluminum oxide matrix. The aluminum oxide is believed to have undergone a crystalline-to-amorphous transition caused by alpha-particle bombardment during the decay of the plutonium.

To develop an adequate knowledge base to definitively judge the usefulness of the remediation technology requires some basic research in how the contaminants are bound in the soil. In this study, the classic five-step sequential extractions were performed on heavy-metal-contaminated soil from Aberdeen Proving Ground to determine the speciation of the metal forms. This technique speciates the heavy metal distribution into an easily extractable (exchangeable) form, carbonates, reducible oxides, organically-bound forms, and residual forms. In order to compare the results of these fractionations with the amount of heavy metals extracted by chelating agents, multi-stage extractions with EDTA were also performed. The results were used to determine the feasibility of using soil washing and soil flushing techniques for remediating the Aberdeen metals-contaminated soils.

In this paper, structural analyses of these concrete vaults subjected to various natural hazards are described, emphasizing the northwest shallow vault. The natural phenomenon hazards considered include both earthquakes and tornados. Because these vaults are deeply embedded in the soil, the SASSI (System Analysis of Soil-Structure Interaction) code was utilized for the seismic calculations. The ultimate strength method was used to analyze the reinforced concrete structures. In all studies, moment and shear strengths at critical locations of the storage vaults were evaluated. Results of the structural analyses show that almost all the waste storage vaults meet the code requirements according to ACI 349-85.

The authors have developed improved methods for the separation of environmental levels of technetium-99, radium, and actinides from soil and water; separation of actinides from soil and water matrix interferences; and isolation of strontium. Among the novel techniques for separation that are being used are element and class-specific resins and membranes. The authors have also developed methods for the simultaneous detection of multiple isotopes by using inductively coupled plasma-mass spectrometry (ICP-MS). Because of its mass-selective mode of detection, ICP-MS requires less rigorous chemical separations than does radiochemical analysis. In addition, improvements in the limits of detection, the volume of the sample and the time of analysis were obtained by using other techniques of sample introduction, such as ultrasonic nebulization, automated batch separation and electrothermal vaporization. Investigation of integration and automation of the separation methods with the ICP-MS method using flow injection analysis is underway. A solid scintillation device has been developed and tested for measurement and identification of low-energy beta-emitting radionuclides; application of this technique will eliminate the generation of mixed-waste counting cocktails. The final product of all activities will be methods that are available and are acceptable for use in regulatory situations. Concerted efforts are being made to facilitate implementation of the methods at DOE sites to realize the improvements offered.

For determining inorganic constituents, alternative methods were studied for sample introduction into inductively coupled plasma spectrometers. Figures of merit for the alternative methods, as well as their associated waste volumes, were compared with the conventional approaches. In the radiological area, the authors are comparing conventional methods for gross alpha/beta measurements of soil samples to an alternative method that uses high-pressure microwave dissolution. For determination of organic constituents, microwave-assisted extraction was studied for RCRA regulated semivolatile organics in a variety of solid matrices, including spiked samples in blank soil; polynuclear aromatic hydrocarbons in soils, sludges, and sediments; and semivolatile organics in soil. Extraction efficiencies were determined under varying conditions of time, temperature, microwave power, moisture content, and extraction solvent. Solvent usage was cut from the 300 mL used in conventional extraction methods to about 30 mL. In most cases, the microwave-assisted extraction technique was as efficient as the more common Soxhlet or sonication extraction techniques.

The structure considered is a single-degree-of-freedom (SDF) system with an active bracing device. The feedforward neural network architecture and an adaptive backpropagation training algorithm is used in the study. The neural net is trained to reproduce the function that represents the response-excitation relationship of the SDF system under seismic loads. In the backpropagation training algorithm, the learning rate is determined by ensuring the decrease of the error function at each epoch. The computer program implemented is validated by solving the classification of the XOR problem. Then, the trained ANN is used to compute the control force according to the control strategy. The ground motions considered in the numerical example are the 1940 El Centro earthquake and the 1979 Imperial Valley earthquake in California. The system responses with and without the control are calculated and compared. The feasibility and potential of applying ANNs to seismic active control is asserted by the promising results obtained from the numerical examples studied.

AN - 52750478; 1997-021812 AB - Time-series observations of water temperature, water transparency, and current velocity at four stations in southeastern Lake Michigan show that the benthic nepheloid layer is probably not maintained by the local resuspension of bottom sediment. Local resuspension may occasionally occur in the deep parts of the lake, but it seems likely that vertical mixing and offshore advection of sediment-laden water maintain the benthic nepheloid layer during most of the year. Although sediment trap data have been interpreted as indicating that local resuspension does occur, it is more likely that the increased sediment fluxes observed near the bottom are due to vertical redistribution of material already in suspension.

The use of seismic isolation has recently proven to be an effective means to mitigate earthquake damage. With seismic isolation, the structures are decoupled from the strong horizontal ground accelerations. The use of high damping elastomer, steel laminated seismic isolation bearings has been proven to be an effective method for seismic base isolation. This paper describes recent research conducted at Argonne National Laboratory to find the mechanical response characteristics of a suite of elastomers compounded for use in elastomeric seismic isolation bearings. The response characteristics were obtained by testing small coupons of each elastomer in a high precision dynamic testing machine. Specifically, the paper reports on tests performed to find the variations in stiffness and energy dissipation with strain level, loading rate, and cycle number. The paper also reports on the effects that strain level has on stiffness recovery.

(LITCO) for the immobilization of calcined radioactive wastes. The objective is to use accelerated corrosion tests as an aid in developing durable waste form compositions. This is a report of tests performed on two LITCO glass compositions, Formula 127 and Formula 532. The main avenue for release of radionuclides into the environment in a geologic repository is the reaction of a waste glass with ground water, which alters the glass and releases its components into solution. These stages in glass corrosion are analyzed by using accelerated laboratory tests in which the ratio of sample surface area to solution volume, SA/V, is varied. At low SA/V, the solution concentrations of glass corrosion products remain low and the reaction approaches the forward rate. At higher SA/V the solution approaches saturation levels for glass corrosion products. At very high SA/V the solution is rapidly saturated in glass corrosion products and secondary crystalline phases precipitate. Tests at very high SA/V provide information about the composition of the solution at saturation or, when no solution is recovered, the identities and the order of appearance of secondary crystalline phases. Tests were applied to Formula 127 and Formula 532 glasses to provide information about the interim and long-term stages in glass corrosion.

Solution compositions, including transuranics, have been periodically determined, and selected analyses of colloid formation and composition, glass corrosion layers, and solid alteration phases have been obtained by scanning and analytical transmission electron microscopies. The importance of integrated testing has been demonstrated, as complex interactions among the glass, the groundwater, and the sensitized stainless steel have been observed. The cumulative releases of both glass-forming and dopant elements are presented along with identification of reaction phases and their partitioning between solution and solid phases. Alteration phases, including smectite clay, iron silicates, uranium silicates, and calcium thorium phosphate, have been observed forming on the glass and stainless steel and have occasionally been found suspended in solution as colloids. Actinides, except neptunium, concentrate into alteration phases or sorb onto the stainless steel. The subsequent transport of the actinides is then controlled by these phases.

Site characterization data, however, present particular problems to technical analysts and decision-makers. Such data are four dimensional, incorporating temporal and spatial components. Their sheer volume can be daunting--sites with hundreds of monitoring wells and thousands of samples sent for laboratory analyses are not uncommon. Data are derived from a variety of sources, including laboratory analyses, non-intrusive geophysical surveys, historical information, bore logs, in-field estimates of key physical parameters such as aquifer transmissivity, soil moisture content, and depth-to-water table. Ultimately, decisions have to be made based on data that are always incomplete, often confusing, inaccurate, or inappropriate, and occasionally wrong. In response to this challenge, two approaches to environmental decision support have arisen, Data Quality Objectives (DQOS) and the Observational Approach (OA). DQOs establish criteria for data collection by clearly defining the decisions that need to be made, the uncertainty that can be tolerated, and the type and amount of data that needs to be collected to satisfy the uncertainty requirements. In practice, DQOs are typically based on statistical measures. The OA accepts the fact that the process of characterizing and remediating contaminated sites is always uncertain. Decision-making with the OA is based on what is known about a site, with contingencies developed for potential future deviations from the original assumptions about contamination nature, extent, and risks posed.

A hierarchical approach that integrates biotic parameters and ecosystem processes was used to give insight into the mechanisms that lead to alterations in the structure and function of soil ecosystems in contaminated areas. This approach involved (1) a thorough survey of the soil biota to determine community structure, (2) laboratory and field tests on critical ecosystem processes, (3) toxicity trials, and (4) the use of spatial analyses to provide input to the decision-making process.

Recent advances in field screening technologies present the possibility for adaptive sampling programs - programs that adapt or change to reflect sample results generated in the field. A coupled Bayesian/geostatistical methodology can be used to guide adaptive sampling programs. A Bayesian approach quantitatively combines "soft" information regarding contaminant location with "hard" sampling results. Soft information can include historical information, non-intrusive geophysical survey data, preliminary transport modeling results, and past experience with similar sites. Soft information is used to build an initial conceptual image of where contamination is likely to be. As samples are collected and analyzed, indicator kriging is used to update the initial conceptual image. New sampling locations are selected to minimize the uncertainty associated with contaminant extent. An example is provided that illustrates the methodology.

Key parameters studied included soil characteristics, irradiation time, CCl4 concentration, steady-state operating temperature, applied ultrasonic-wave energy, and the ratio of soil to water in the system. The results of the experiments showed that (1) residual CCl4 concentrations could be decreased with longer irradiation periods and (2) detoxification efficiency was proportional to steady-state operating temperature and applied ultrasonic-wave energy. The characteristics of the contaminated soil were found to be an important factor in the design of an ultrasonic detoxification system. A soil-phase CCl4 concentration below 1 ppm (initial concentration of 56 ppm) was achieved through this process, indicating that the application of ultrasonic irradiation is feasible and effective in the detoxification of soil contaminated by organic compounds. On the basis of the experimental results, a schematic of a full-scale ultrasonic soil-detoxification system was developed. Improvements to this novel process are discussed.

To reduce these uncertainties and to increase the probability of successful remediation at minimum cost, a "Phased and pilot" accelerated remedial strategy has been developed for the J-Field area of Aberdeen Proving Ground, Maryland. The strategy includes four phases. First, the most contaminated site is selected as a pilot for detailed investigation. Second, the most contaminated areas within the pilot site are chosen as a pilot source area for interim action study, and a remedial action is developed to remove the primary contaminant sources. The subsequent sitewide investigation uses the effective tools developed in the first phase. Third, a cleanup operation is initiated in the pilot source area, while a sitewide feasibility study is developed by taking advantage of lessons learned in the interim action. Fourth, a sitewide cleanup operation proceeds.

The 88-ha (217-acre) chemical plant area is chemically and radioactively contaminated as a result of uranium processing activities conducted by the U.S. Atomic Energy Commission during the 1950s and 1960s. The Army also used the chemical plant area for the production of explosives in the 1940s. Adjacent to the chemical plant area is another NPL site known as the Weldon Spring Ordnance Works.

The facility consisted of 129 cast-iron pipes cast vertically in a concrete monolithic structure. The objects were packaged and placed into the pipes for storage prior to disposal or reuse in research experiments. Deterioration of the facility allowed water to enter the pipes. Release of this contaminated water has resulted in radiological contamination of underlying soil and groundwater. Sediment, principally corrosion products, collected in the bottom of the pipes. Decontamination and decommissioning of the Map Tube Facility generated a large quantity of radioactive mixed and low-level waste. All low-level and mixed waste that can not be treated on-site is sent to the Westinghouse Hanford Company (WHC) in Richland, Washington for storage or disposal. Because of the difficulty and cost of disposing radioactive mixed waste, a great amount of effort was expended to limit the mixed waste volume. The final volume of mixed waste was approximately 99 percent less than originally generated with total waste disposal costs being reduced by roughly two-thirds.

Estimates vary, but two million analyses annually are expected. The waste generated by the analytical procedures used for characterizations is a significant source of new DOE waste. Success in reducing the volume of secondary waste and the costs of handling this waste would significantly decrease the overall cost of this DOE program. Selection of appropriate analytical methods depends on the intended use of the resultant data. It is not always necessary to use a high-powered analytical method, typically at higher cost, to obtain data needed to make decisions about waste management. Indeed, for samples taken from some heterogeneous systems, the meaning of high accuracy becomes clouded if the data generated are intended to measure a property of this system. Among the factors to be considered in selecting the analytical method are the lower limit of detection, accuracy, turnaround time, cost, reproducibility (precision), interferences, and simplicity. Occasionally, there must be tradeoffs among these factors to achieve the multiple goals of a characterization program. The purpose of the work described here is to add waste minimization to the list of characteristics to be considered. In this paper the authors present results of modifying analytical methods for waste characterization to reduce both the cost of analysis and volume of secondary wastes. Although tradeoffs may be required to minimize waste while still generating data of acceptable quality for the decision-making process, they have data demonstrating that wastes can be reduced in some cases without sacrificing accuracy or precision.

The Argonne ESC process emphasizes an interdisciplinary approach in which all available information is integrated to produce as complete a picture as possible of the geologic and hydrologic controls on contaminant distribution and transport. As part of this process, all pertinent data that have been collected from previous investigations are thoroughly analyzed before a decision is made to collect additional information. A seismic reflection program recently concluded at the site had produced inconclusive results. Before we decided whether another acquisition program was warranted, we examined the existing data set to evaluate the quality of the raw data, the appropriateness of the processing sequence, and the integrity of the interpretation. We decided that the field data were of sufficient quality to warrant reprocessing and reinterpretation. The main thrust of the reprocessing effort was to enhance the continuity of a shallow, low-frequency reflection identified as a perching horizon within the Ogallala Formation. The reinterpreted seismic data were used to locate the boundaries of the perched aquifer, which helped to guide the Argonne ESC drilling and sampling program. In addition, digitized geophysical well log data from previous drilling programs were reinterpreted and integrated into the geologic and hydrogeologic model.

Complex and large-amplitude anomalies caused by above ground metal in this area obscure many smaller features produced by subsurface sources. No underground storage tanks were found in the areas surveyed. Major anomalies produced by subsurface sources include the following: EM-61 and EM-31 lineaments caused by a water line extending north from the south fence; a broad positive magnetic anomaly caused by magnetic fill north of the material and drum storage area and northeast of E3640; a 30-ft-wide band of EM-31 anomalies extending from the front gate to the southeast corner of E3640 and a coincident EM-61 anomaly produced by buried utilities; ground-penetrating radar images along three lines extending from a sump at the northeast corner of E3640 to the eastern fence; and EM-61, EM-31, and magnetic anomalies caused by overhead and underground pipes extending south from the north fence.

These systems are expensive to install and maintain. A traditional approach to designing such a wellfield uses a series of trial-and-error simulations to test the effects of various well locations and pump rates. However, the optimal locations and pump rates of extraction wells are difficult to determine when objectives related to the site hydrogeology and potential pumping scheme are considered. This paper describes a case study of an application of linear programming theory to determine optimal well placement and pump rates. The objectives of the pumping scheme were to contain contaminant migration and reduce contaminant concentrations while minimizing the total amount of water pumped and treated. Past site activities at the area under study included disposal of contaminants in pits. Several groundwater plumes have been identified, and others may be present. The area of concern is bordered on three sides by a wetland, which receives a portion of its input budget as groundwater discharge from the pits. Optimization of the containment pumping scheme was intended to meet three goals: (1) prevent discharge of contaminated groundwater to the wetland, (2) minimize the total water pumped and treated (cost benefit), and (3) avoid dewatering of the wetland (cost and ecological benefits). Possible well locations were placed at known source areas. To constrain the problem, the optimization program was instructed to prevent any flow toward the wetland along a user-specified border. In this manner, the optimization routine selects well locations and pump rates so that a groundwater divide is produced along this boundary.

This project focuses on improvement of radioanalytical methods with an emphasis on faster and cheaper routine methods. We have developed improved methods, for separation of environmental levels of technetium-99 and strontium-89/90, radium, and actinides from soil and water; and for separation of actinides from soil and water matrix interferences. Among the novel separation techniques being used are element- and class-specific resins and membranes. (The 3M Corporation is commercializing Empore (super TM) membranes under a cooperative research and development agreement (CRADA) initiated under this project). We have also developed methods for simultaneous detection of multiple isotopes using inductively coupled plasma-mass spectrometry (ICP-MS). The ICP-MS method requires less rigorous chemical separations than traditional radiochemical analyses because of its mass-selective mode of detection. Actinides and their progeny have been isolated and concentrated from a variety of natural water matrices by using automated batch separation incorporating selective resins prior to ICP-MS analyses. In addition, improvements in detection limits, sample volume, and time of analysis were obtained by using other sample introduction techniques, such as ultrasonic nebulization and electrothermal vaporization. Integration and automation of the separation methods with the ICP-MS methodology by using flow injection analysis is underway, with an objective of automating methods to achieve more reproducible results, reduce labor costs, cut analysis time, and minimize secondary waste generation through miniaturization of the process.

Water comprises a mixture of magmatic (rock-equilibrated at high temperature) and meteoric, with the relative proportions varying through time. Carbon isotopes are most consistent with a mantle source, although other contributions to the system cannot be ruled out. Nitrogen most likely originated from organic matter in subducted oceanic sediments. All of these "primary" components have been modified somewhat by interaction or exchange with other reservoirs during ascent to the surface. In addition to information on the origin of the gases, these data show significant temporal variations precursory to eruptive events. Chemical ratios change and water becomes more meteoric in character prior to eruptions.

The corrosion mechanism of nuclear waste glasses must be known in order to provide source terms describing radionuclide release for performance assessment calculations. Different DWPF reference glasses were corroded under conditions that highlighted various aspects of the corrosion process and led to different extents of corrosion. The glasses corroded by similar mechanisms, and a phenomenological description of their corrosion behavior is presented here. The initial leaching of soluble glass components results in the formation of an amorphous gel layer on the glass surface. The gel layer is a transient phase that transforms into a layer of clay crystallites, which equilibrates with the solution as corrosion continues. The clay layer does not act as a barrier to either water penetration or glass dissolution, which continues beneath it, and may eventually separate from the glass. Solubility limits for glass components may be established by the eventual precipitation of secondary phases; thus, corrosion of the glass becomes controlled by the chemical equilibrium between the solution and the assemblage of secondary phases. In effect, the solution is an intermediate phase through which the glass transforms to an energetically more favorable assemblage of phases. Implications regarding the prediction of long-term glass corrosion behavior are discussed.

In particular, problems associated with light non-aqueous phase liquids (LNAPLs) such as gasoline, diesel fuel, and jet fuels are becoming more common. This paper presents the development and application of an analytical model for predicting LNAPL concentrations at the water table. Based on the volume of the spill, the model has two parts: a pancake model for predicting the behavior of the LNAPL if the spill volume is large enough to reach the water table; and an advection/dispersion model that assumes that the LNAPL does not reach the water table as a slug, but creates a contaminated soil layer from which soluble LNAPL components can be mobilized and transported vertically downward while undergoing advection, dispersion, sorption, volatilization, and biodegradation. Maximum and current concentrations are calculated at the water table for the pancake model using a solubility-limited approach, and an analytical expression derived using Laplace transforms for the advection/dispersion model. The behavior and sensitivity of the model is evaluated for a hypothetical site using an LNAPL having ten components that represent a cross section of organic compounds commonly found in spills including BTEX, branch alkanes, and polynuclear aromatic hydrocarbons. Results of the study indicate that the most important LNAPL group is the BTEX compounds, and that of these, benzene would have the largest maximum concentration at the water table because of its relatively long biodegradation half-life. Other parameters of importance include total precipitation, depth to the water table, and the fraction of organic carbon in the soil.

Factors affecting uncertainties in Kd values and contaminant transport modelling are discussed. Transport of cadmium(II) in a laboratory soil column was compared with computer predicted values. Measured and literature Kd values provided approximations of sorption of inorganic ions when experimental pH and electrolyte composition and soil type were similar to those being measured. Data from experimental batch systems were better predictors of the time of breakthrough of pollutant then literature-derived values of Kd.

Various actinide separation schemes were developed. The material was characterized by preferential retention of tetravalent actinides over a wide range of acidities. It was used to separate and preconcentrate selected actinides from high-level nuclear waste solutions for subsequent determination. Americium, thorium, neptunium, plutonium and uranium were separated from one another and from a variety of matrix components. There are 32 references.

The model distinguished 3 components in the mercury system: elemental, particulate and gaseous divalent mercury. Wet and dry deposition directly to the Great Lakes of mercury emitted by anthropogenic activities were estimated at 1.44 and 2.46 tonnes per year, respectively. The corresponding values for mercury emitted by natural processes were 0.15 and 0.39 tonnes per year. Emission control in North America would substantially reduce inputs to the Great Lakes.

A cation exchange column was used to separate the radium isotopes from the matrix. Optimal separation was obtained when 100 ml of 1.5 M hydrochloric acid was used for washing and 45 ml of 6 M hydrochloric acid was used as elutant. After preconcentration and separation, the radium was electrodeposited onto a stainless steel disc. Electrodeposition conditions were optimal when 400 ug of platinum were added, ammonium oxalate and hydrochloric acid were used as the electrolyte solution and an electrodeposition current of 600 mA was used. The calibration graph was linear for 3.3-340 mBq radium-226 per ml. Detection limits were 0.18 mBq for radium-226 and 0.29 mBq for radium-224. Recoveries of radium-226 and radium-224 were 90-100 per cent when samples of drinking water, well water and dissolved bones were analysed.

The isolate used phenol as the sole source of carbon and energy and converted it to acetic acid. There was no further metabolism of the acetic acid, even after a long incubation period of 30 d. The isolate, which might be a Desulfovibrio sp., could also degrade p-chlorophenol as the sole carbon source. It could not, however, degrade dichlorophenol and pentachlorophenol which contained 2 or more chlorine atoms. The isolate might be used for treating phenol- and p-chlorophenol containing wastewaters under anaerobic conditions.

AN - 77743355; 7870761 AB - The photochemistry of 4'-aminomethyl-4,5',8-trimethylpsoralen (AMT) with poly(dA-dT) and calf thymus DNA was studied. The extent of photoadduct formation and the distribution of photoadducts (3,4- and 4',5'-monoadducts and crosslinks) were determined by liquid scintillation analysis and HPLC, respectively. The adducts were characterized on the basis of their UV absorption spectra and mass spectral analysis. The high DNA binding constant for AMT (1.5 x 10(5) M-1) led to a high fraction of intercalated molecules, which contributed to the high level of AMT photoadduct formation, as many as 102 adducts per kilobase pair. In addition, there is a distinct difference in the adduct distribution compared to the previously studied 8-methoxypsoralen (8-MOP). Under the conditions employed for the photochemical studies, virtually all of the AMT molecules in solution are intercalated, occupying 25% of the base pair sites. Under similar conditions, 8-MOP molecules occupied 10 times fewer sites. Thus, for AMT, DNA base pair sites other than 5'TA, the well-characterized strong binding for psoralens in general, are an additional target for photomodification, which results in the formation of a higher percentage of monoadducts. The proportion of photoadducts formed was virtually independent of AMT concentration and UVA (320-400 nm radiation) fluence.

This information is of interest in two ways. First, it is hoped that a relationship might be established between the amount of each metal determined after extraction by the TCLP and the amount determined using a total determination method. Second, data are also presented which indicate the general extractability of various metals in soil samples using the TCLP. This study looks specifically at inorganic elements (Sb, As, Ba, Cd, Cu, Cr, Pb, Mg, Hg, Se, Ag, Sn, and Zn) in soils from a firing range. Results show that total determination methods for metals can not generally be used for heterogeneous samples, such as soil samples from a firing range. Some correlation between a total determination method and TCLP was observed when Ba and Cd were present in the samples at lower concentrations (less than 80 mg/kg for Ba and less than 25 mg/kg for Cd); however, additional data are necessary to verify this correlation.

This site has been identified for remedial action under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended by the Superfund Amendments and Reauthorization Act of 1986. Single-nuclide guidelines were derived on the basis of the requirement that the 50-year committed effective dose equivalent to a hypothetical individual who lives or works in the immediate vicinity of OU IV should not exceed a dose constraint of 30 mrem/yr following remedial action for the current use and plausible future use scenarios or a dose limit of 100 mrem/yr for plausible but less likely future use scenarios. The US Department of Energy (DOE) residual radioactive material guideline computer code, RESRAD, was used in this evaluation; RESRAD implements the methodology described in the DOE manual for determining residual radioactive material guidelines. Four potential scenarios were considered; each assumed that, for a period of 1,000 years following remedial action, the site would be used without radiological restrictions. The four scenarios varied with regard to the type of site use, time spent at the site, and sources of food consumed.

WAG 2 is the major drainage system downgradient of other WAGs that contain significant sources of contamination at ORNL. Field activities to support the remedial investigation for the RI portion include characterization of the nature and extent of contamination in WAG 2 (consisting of White Oak Creek (WOC) and associated tributaries and floodplain, White Oak Lake (WOL), and White Oak Creek Embayment (WOCE)), specifically to support risk-based remediation decisions. The project consists of three phases: Phase 1, initial scoping characterization to determine the need for early action; Phase 2, interim activities during remediation of upslope WAGs to evaluate potential changes in the contamination status of WAG 2 that would necessitate revaluation of the need for early action; and Phase 3, completion of the RI process following remediation of upslope WAGs. Overall RI objectives, consistent with ORNL Environmental Restoration (ER) Program strategic objectives to reduce risks and comply with environmental regulations, are discussed in the WAG 2 Remedial Investigation Plan.

AN - 77747687; 7854145 AB - Independent Chinese hamster ovary (CHO)-K1 cell mutants at the hypoxanthine-guanine phosphoribosyltransferase (hprt) locus were isolated from untreated, 60Co gamma ray- and 212Bi alpha-exposed cells and the genetic changes underlying the mutation determined by multiplex polymerase chain reaction (PCR)-based exon deletion analysis. In the 71 spontaneous mutants analyzed, 77.5% of the clones showed no change in exon number or size, 15.5% showed a loss of a single exon, 4.2% showed a loss of 2-8 exons, and 2.8% showed loss of all nine hprt exons (total gene deletion). Exposure to 6 Gy of gamma rays, which reduced survival levels to 10%, produced a significantly different deletion spectrum that was shifted toward deletions with 45% of the 20 mutants analyzed showing a loss of a single exon and 30% showing a loss of all nine exons. Exposure to 2 Gy alpha radiation from 212Bi, a 220Rn daughter, a dose which also reduced survival levels to about 10%, resulted in a deletion spectrum similar to the gamma-ray spectrum in that more than 75% of the 49 mutants analyzed were deletions. The alpha spectrum, however, was significantly different from both the spontaneous and gamma spectra with 55.1% of the alpha mutants showing a loss of all nine exons, 10.2% showing loss of a single exon, and 14.3% showing loss of 2-8 exons. Thus, alpha-radiation appears to produce larger intragenic deletions than gamma radiation. The results suggest that intragenic deletion size should be considered when low- and high linear energy transfer (LET) mutation spectra are compared.

Fracture flow codes of varying capability in the public and private domain were identified in a survey of government, academia, and industry. The selection and use of an appropriate code requires conceptualization of the geology, physics, and chemistry (for transport)of the fracture flow problem to be solved. Conceptual models that have been invoked to describe fluid flow in fractured porous media include explicit discrete fracture, dual continuum (porosity and/or permeability), discrete fracture network, multiple interacting continua, multipermeability/multiporosity, and single equivalent continuum. Of these, the dual-continuum model is the most widely employed. The concept of multiple interacting continua has been applied in a limited number of examples. Multipermeability/multiporosity provides a unified conceptual model.

Seismic refraction and reflection data and electrical resistivity data have aided in the characterization of the leaky confining unit at the base of the surficial aquifer (designated Unit B of the Tertiary Talbot Formation). Excellent reflectors have been observed for both upper and lower surfaces of Unit B that correspond to stratigraphic units observed in boreholes and on gamma logs. Elevation maps of both surfaces and an isopach map of Unit B, created from reflection data at the toxic burning pits site, show a thickening of Unit B to the east. Abnormally low seismic compressional-wave velocities suggest that Unit B consists of gassy sediments whose gases are not being flushed by upward or downward moving groundwater. The presence of gases suggests that Unit B serves as an efficient aquitard that should not be penetrated by drilling or other activities. Electromagnetic, total-intensity magnetic, and ground-penetrating radar surveys have aided in delineating the limits of two buried trenches, the VX burning pit and the liquid smoke disposal pit, both located at the toxic burning pits site. The techniques have also aided in determining the extent of several other disturbed areas where soils and materials were pushed out of disposal pits during trenching activities. Surveys conducted from the Prototype Building west to the Gunpowder River did not reveal any buried trenches.

The complementary methods of electromagnetic surveying, vertical electrical soundings, and seismic refraction profiling were successful in determining the depth and configuration of the bedrock surface, the character of the unconsolidated deposits resting on the bedrock surface, and the nature of the bedrock surface. Channels and other depressions in the bedrock surface are aligned with structurally induced fractures in the bedrock. The unconsolidated deposits consist of coarse alluvium and colluvium, which are confined to these channels and other depressions, and fine-grained loam and loess, which cover most of the Lautertal. Wide ranges in the electrical and elastic parameters of the bedrock surface are indicative of carbonate rock that is highly fractured and dissolved at some locations and competent at others. Most local groundwater recharge occurs in the uplands where the Middle Kimmeridge (Delta) Member of the Malm Formation (Jurassic) is widely exposed. These carbonate rocks are known to be susceptible to dissolution along the fractures and joints; thus, they offer meteoric waters ready access to the main shallow aquifers lower in the Malm Formation. These same rocks also form the bedrock surface below many of the dry valleys, but in the Lautertal, the infiltration of meteoric waters into the subsurface is generally impeded by the surficial layer of fine-grained loam and loess, which have low hydraulic conductivity. Further, the rocks of the Middle Kimmeridge Member appear to be closely associated with the localized occurrence of turbidity in such perennial streams as the Lauterach.

Surveys repeatedly identify widespread dread & fear of community stigma, but negative economic effects related to nuclear site proximity have not been empirically demonstrated. Also, there is a gap between the distance from a site people would prefer to live & the distance they are willing to live. Many people who say they do not want to live near a reactor actually do live near one & do not know it. People express fears of catastrophic accidents at high levels, but rarely take actions to avoid nuclear sites or transport corridors. Federal policymakers should not change policy based on subjective fears that are not accompanied by proven negative impact. In Comment on William C. Metz's "Potential Impacts of Nuclear Activities on Local Economies: Rethinking the Issue", Kai Erikson (Yale U, New Haven, CT) agrees that negative perceptions of nuclear sites need further study, but disagrees with the implication that the federal siting program should continue unquestioned in the meantime. In Stigma Happens: Social Problems in the Siting of Nuclear Waste Facilities, Paul Slovic, James Flynn, & Robin Gregory (Decision Research, 1201 Oak St, Eugene, OR 97401) argue that Metz misunderstands or misrepresents the research. A review of evidence documents real negative social & economic effects of perceived risk. Stigma of sited communities is a real phenomenon. E.

The information gained from these studies is being used to develop and test remediation technologies. Investigations using SEM have shown that uranium is contained within particles that are typically 1 to 100 mu m in diameter. Further analysis with AEM has shown that these uranium-rich regions are made up of discrete uranium-bearing phases. The distribution of these uranium phases was found to be inhomogeneous at the microscopic level.

The Purus system consists of four reactor chambers, each containing a xenon flash lamp. During the two weeks of testing, samples were taken and analyzed from the inlet and outlet sides of the Purus system. The contaminants of concern on the inlet were tetrachloroethylene (PCE), trichloroethylene (TCE), and 1,1,1-trichloroethane (TCA); the contaminants of concern on the outlet were PCE, TCE, TCA, carbon tetrachloride (CT), and chloroform. The evaluation of the Purus system included an examination of the reduction of both TCE and PCE and a search for any change in the concentrations. (Operating conditions included flow rates, ranging from 25 to 100 standard cubic feet per minute; inlet concentration of PCE, ranging from 360 to 10,700 parts per million volume; and flash lamp rates, ranging from 1 to 30 hertz.) The Purus system was quite efficient at reducing the concentrations of both PCE and TCE. The potential by-products, TCA, CT, and chloroform, showed no significant increases throughout the range of the various operating parameters. Overall, the Purus system appears to be a cost-efficient means of reducing the concentrations of PCE and TCE, while the removal of the initial photo-oxidation products and TCA is slower and needs further evaluation.

AN - 76697218; 8083228 AB - The requirement for protein kinase C (PKC)-beta in phorbol 12-myristate 13-acetate (PMA)-induced macrophage differentiation of human HL-60 promyelocytic leukemia cells was studied by using the variant HL-525, which is deficient in PKC-beta and is resistant to PMA-induced differentiation. Transfecting these resistant HL-525 cells with expression vectors containing either PKC-beta I or PKC-beta II cDNA resulted in clones that displayed PKC-beta transcript levels similar to or higher than those of the parental HL-60 cells or cells from a PMA-susceptible HL-60 clone, HL-205. These productive transfectants also exhibited PMA-induced cell attachment and spreading, inhibition of cell replication, reactivity to the OKM1 monoclonal antibody, and the ability to phagocytize opsonized beads, which are all characteristic macrophage markers. No PMA-induced differentiation markers were observed in any of the PKC-beta I or PKC-beta II transfectants that did not exhibit an increased PKC-beta RNA level or in cells transfected with control plasmids. These results indicate that restoration of the PKC-beta isozyme deficiency by productive gene transfection causes HL-525 cells to revert to a phenotype like that of the parental HL-60 cells, which is characterized by susceptibility to PMA-induced macrophage differentiation. Therefore, we can conclude that PKC-beta is one of the essential elements in the PMA-induced signal transduction pathway which leads to macrophage differentiation in HL-60 cells and perhaps in other related cell types.

AN - 76933280; 7819137 AB - To investigate a possible relationship between apoptosis induction and protein phosphorylation in human breast carcinoma cells, we treated three such cell types, MB-231, MCF-7, and AU-565, with okadaic acid (OA), an inhibitor of protein phosphatases 1 and 2A, or phorbol 12 myristate 13-acetate, an activator of protein kinase C. We then examined these cells for the appearance of apoptosis markers. While OA caused multiplication arrest and cytotoxicity in all three cell lines, apoptosis was induced in MB-231 and MCF-7 cells but not in AU-565 cells. A similar cell-specific apoptosis induction was also observed after treatment with dinophysistoxin-1 (an active OA analogue) and with calyculin A (a structurally unrelated protein phosphatase inhibitor) but not with analogues that either are inactive or penetrate epithelial cells poorly. Phorbol 12-myristate 13-acetate also inhibited cell multiplication but was without effect in inducing apoptosis in these cells. Levels of the apoptosis-inhibitory protein BCL2 were examined in these cells, but they did not correlate with this differential susceptibility. We additionally treated the three cell types with 1-beta-D-arabinofuranosylcytosine and genistein to determine whether the AU-565 cell line would also be resistant to apoptosis induction by other chemical stimuli. Both of these agents led to the induction of apoptosis in all three cell lines. These results indicate that the AU-565 cells are specifically resistant to apoptosis induction by inhibitors of protein phosphatases 1 and 2A. This cell-specific resistance may thus allow one to identify cellular mediators of apoptosis by comparing protein phosphorylation patterns in these cells before and after treatment with OA or related inhibitors.

AN - 76649740; 8056599 AB - A group of stack effluent monitoring systems have been developed to monitor discharges of 220Rn from a hot cell facility at Argonne National Laboratory. The stack monitors use flow-through scintillation cells and are completely microprocessor-based systems. A method for calibrating the stack monitors in the laboratory and in the field is described. A nominal calibration factor for the stack monitoring systems in use is 15.0 cts min-1 per kBq m-3 (0.56 cts min-1 per pCi L-1) +/- 26% at the 95% confidence level. The plate-out fraction of decay products in the stack monitor scintillation cells, without any pre-filtering, was found to be nominally 25% under normal operating conditions. When the sample was pre-filtered upstream of the scintillation cell, the observed cell plate-out fraction ranged from 16-22%, depending on the specific sampling conditions. The instantaneous 220Rn stack concentration can be underestimated or overestimated when the steady state condition established between 220Rn and its decay products in the scintillation cell is disrupted by sudden changes in the monitored 220Rn concentration. For long-term measurements, however, the time-averaged response of the monitor represents the steady state condition and leads to a reasonable estimate of the average 220Rn concentration during the monitoring period.

AN - 76845005; 7968578 AB - The polyamine spermine and the disulfide N,N"-(dithiodi-2,1-ethanediyl)bis-1,3-propanediamine (WR-33278) are structurally similar agents capable of binding to DNA. WR-33278 is the disulfide moiety of the clinically studied radioprotective agent S-2-(3-aminopropylamino)ethylphosphorothioic acid (WR-2721). Because of their reported structural and functional similarities, it was of interest to compare their effects on cell survival and mutation induction at the hypoxanthine-guanine phosphoribosyl transferase (hprt) locus in Chinese hamster AA8 cells. WR-33278 and spermine (at concentrations of 0.01 and 0.001 mM) were electroporated into cells. Electroporation, 300 V and 125 microF, was performed either 30 min prior to or 3 h following exposure of cells to 750 cGy of ionizing radiation. Electroporation alone reduced cell survival to 75% but had no effect on hprt mutation frequency. The electroporation of either spermine or WR-33278 at concentrations greater than 0.01 mM was extremely toxic. The exposure of cells to both electroporation and irradiation gave rise to enhanced cell killing and mutation induction, with the sequence of irradiation followed 3 h later by electroporation being the more toxic protocol. Cell survival was only enhanced following electroporation of 0.01 mM of spermine and WR-33278 30 min prior to irradiation. Protection against radiation-induced hprt mutations was observed for both spermine and WR-33278 under all experimental conditions tested. Spermine at exposure concentrations of 0.01 and 0.001 mM administered 30 min before or 3 h after irradiation reduced mutation frequencies by factors of 2.2, 1.2, 1.9 and 2.2, respectively.(ABSTRACT TRUNCATED AT 250 WORDS) JF - Mutagenesis AU - Shigematsu, N AU - Schwartz, J L AU - Grdina, D J AD - Center for Mechanistic Biology and Biotechnology, Argonne National Laboratory, IL 60439.

Because the base is to be closed and turned over to the city of Alexandria in 1995, the Army sought the most rapid and cost-effective means of spill remediation. At the request of the Baltimore District of the US Army Corps of Engineers, Argonne conducted a pilot-scale study to determine the feasibility of vapor extraction and bioventing for resolving remediation problems and to critique a private firm's vapor-extraction design. Argonne staff, working with academic and private-sector participants, designed and implemented a new systems approach to sampling, analysis and risk assessment. The US Geological Survey's AIRFLOW model was adapted for the study to simulate the performance of possible remediation designs. A commercial vapor-extraction machine was used to remove nearly 500 gal of gasoline from Argonne-installed horizontal wells. By incorporating numerous design comments from the Argonne project team, field personnel improved the system's performance. Argonne staff also determined that bioventing stimulated indigenous bacteria to bioremediate the gasoline spin. The Corps of Engineers will use Argonne's pilot-study approach to evaluate remediation systems at field operation sites in several states.

It addresses the current status, projected data requirements, and recommended actions for five study areas within the 100 Area: the Lime Sludge Pond, the Building 108 Liquid Retention Pond, the Coal Yard, the East Area Burn Pit, and the Eastern Perimeter Area. Two of these areas are solid waste management units under the Resource Conservation and Recovery Act (the Lime Sludge Pond and the Building 108 Liquid Retention Pond); however, the Illinois Environmental Protection Agency has determined that no further action is necessary for the Lime Sludge Pond. Operational records for some of the activities were not available, and one study area (the East Area Burn Pit) could not be precisely located. Recommendations for further investigation include sample collection to obtain the following information: (1) mineralogy of major minerals and clays within the soils and underlying aquifer, (2) pH of the soils, (3) total clay fraction of the soils, (4) cation exchange capacity of the soils and aquifer materials, and (5) exchangeable cations of the soils and aquifer material. Various other actions are recommended for the 100 Area, including an electromagnetic survey, sampling of several study areas to determine the extent of contamination and potential migration pathways, and sampling to determine the presence of any radionuclides. For some of the study areas, additional actions are contingent on the results of the initial recommendations.

Plant materials and soil from the root zone were sampled and analyzed to determine TNT uptake under natural field conditions. Standard USATHAMA methods were used to determine concentrations of explosives, their derivatives, and metabolites in the soil samples. No explosives were detected in the aboveground portion of any plant sample. However, results indicate that TNT, 2-aminodinitrotoluene (2-ADNT), and/or 4-ADNT were present in some root samples. The presence of 2-ADNT and 4-ADNT increases the likelihood that explosives were taken up by plant roots, as opposed to their presence resulting from external soil contamination.

The glassy slag waste form is composed of various crystalline and metal oxide phases embedded in a silicate glass phase. The MAWS approach was adopted by blending multiple waste streams to achieve up to 100% waste loadings. The crystalline phases, such as spinels, are very durable and contain hazardous and radioactive elements in their lattice structures. These crystalline phases may account for up to 80% of the total volume of slags having over 80% metal loading. The structural bond strength model was used to quantify the correlation between glassy slag composition and chemical durability so that optimized slag compositions were obtained with limited crucible melting and testing. Slag compositions developed through crucible melts were also successfully generated in a pilot-scale Retech plasma centrifugal furnace at Ukiah, California. Utilization of glassy slag waste forms allows the MAWS approach to be applied to a much wider range of waste streams than glass waste forms. The initial work at ANL has indicated that glassy slags are good final waste forms because of (1) their high chemical durability; (2) their ability to incorporate large amounts of metal oxides; (3) their ability to incorporate waste streams having low contents of flux components; (4) their less stringent requirements on processing parameters, compared to glass waste forms; and (5) their low requirements for purchased additives, which means greater waste volume reduction and treatment cost savings.

To evaluate the effects of ANL operations on the environment, samples of environmental media collected on the site, at the site boundary, and off the ANL site were analyzed and compared to applicable guidelines and standards. A variety of radionuclides was measured in air, surface water, groundwater, soil, grass, and bottom sediment samples. In addition, chemical constituents in surface water, groundwater, and ANL effluent water were analyzed. External penetrating radiation doses were measured and the potential for radiation exposure to off-site population groups was estimated. The results of the surveillance program are interpreted in terms of the origin of the radioactive and chemical substances (natural, fallout, ANL, and other) and are compared with applicable environmental quality standards. A US Department of Energy (DOE) dose calculation methodology, based on International Commission on Radiological Protection (ICRP) recommendations and the CAP-88 version of the EPA-AIRDOSE/RADRISK computer code, is used in this report. The status of ANL environmental protection activities with respect to the various laws and regulations which govern waste handling and disposal is discussed. This report also discusses progress being made on environmental corrective actions and restoration projects from past activities.

The studies are assisting in the location and identification of pipes, tanks, trenches, and liquid waste in the subsurface. Multiple databases have been integrated to provide support for detection of underground utilities and to determine the stratigraphy and lithology of the subsurface. The studies were conducted within the double security fence and exterior to the double fence, down gradient toward the west branch of Canal Creek. To determine if contaminants found in the creek were associated with the Pilot Plant, both the east and west banks were included in the study area. Magnetic, conductivity, inductive emf, and ground-penetrating-radar anomalies outline buried pipes, trenches, and various pieces of hardware associated with building activities. Ground-penetrating-radar imagery also defines a paleovalley cut 30 ft into Potomac Group sediments of Cretaceous age. The paleovalley crosses the site between Building E5654 and the Pilot Plant fence. The valley is environmentally significant because it may control the pathways of contaminants.

The surveillance program is the ongoing remedial action that resulted from the 1976-1978 radiological characterization of the site. That study determined that very low levels of hydrogen-3 (as tritiated water) had migrated from the burial ground and were present in two nearby hand-pumped picnic wells. The current program consists of sample collection and analysis of air, surface and subsurface water, and bottom sediment. The results of the analyses are used to (1) determine the migration pathway of water from the burial ground (Plot M) to the hand-pumped picnic wells, (2) establish if buried radionuclides other than hydrogen-3 have migrated, and (3) generally characterize the radiological environment of the area. Hydrogen-3 in the Red Gate Woods picnic wells was still detected this year, but the average and maximum concentrations were significantly less than found earlier. Tritiated water continues to be detected in a number of wells, boreholes, dolomite holes, and a surface stream. For many years it was the only radionuclide found to have migrated in measurable quantities. Analyses since 1984 have indicated the presence of low levels of strontium-90 in water from a number of boreholes next to Plot M. The available data does not allow a firm conclusion as to whether the presence of this nuclide represents recent migration or movement that may have occurred before Plot M was capped. The results of the surveillance program continue to indicate that the radioactivity remaining at Site A/Plot M does not endanger the health or safety of the public visiting the site, using the picnic area, or living in the vicinity.

AN - 76447780; 8159701 AB - The deposition of certain Bence Jones proteins as tubular casts, basement membrane precipitates, or amyloid fibrils results in the human light-chain-associated renal and systemic diseases--myeloma (cast) nephropathy, light-chain deposition disease, and immunocyte-derived (primary or AL) amyloidosis. To determine if light-chain nephrotoxicity or amyloidogenicity is related to the propensity of these components to form high molecular weight aggregates under physiological conditions, we used a size-exclusion chromatographic system to study 40 different Bence Jones proteins. Each samples was tested over a wide range of protein concentration in three different buffers varying in pH, osmolality, and the presence or absence of low concentrations of urea. Thirty-three of the 35 proteins found clinically and/or experimentally to form in vivo pathologic light-chain deposits were shown to undergo high-order self-association and form high molecular weight aggregates. In contrast, of five nonpathologic proteins, one showed polymerization under the chromatographic conditions used. The correlation between the in vivo results achieved by size-exclusion chromatography and that found in vivo provides (i) a rapid diagnostic method to identify potential nephrotoxic or amyloidogenic Bence Jones proteins and (ii) an experimental means to gain new insight into the physicochemical basis of light-chain aggregation and the treatment of those invariably fatal disorders associated with pathologic light-chain deposition.

AN - 76418062; 8146299 AB - The aminothiol 2-[(aminopropyl)amino]ethanethiol (WR-1065) is the active thiol of the clinically studied radioprotective agent S-2-(3-aminopropylamino)ethylphosphorothioic acid (WR-2721). WR-1065 is an effective radiation protector when it is administered 30 min prior to exposure of Chinese hamster ovary K1 cells to radiation (i.e., a dose modification factor of 1.4) at a concentration of 4 mM. Under these exposure conditions, topoisomerase (Topo) I and II alpha activities and associated protein contents were measured in cells of the K1 cell line using the DNA relaxation assay, the P4 unknotting assay and immunoblotting, respectively. WR-1065 was ineffective in modifying Topo I activity, but it did reduce Topo II alpha activity by an average of 50%. The magnitude of Topo II alpha protein content, however, was not affected by these exposure conditions. The effects on the cell cycle were monitored by the method of flow cytometry. Exposure of cells to 4 mM WR-1065 for up to 6 h resulted in a build-up of cells in the G2/M-phase compartment. However, under these conditions and in contrast to Topo II inhibitors used in chemotherapy, WR-1065 is an effective radioprotective agent capable of protecting against both radiation-induced cell lethality and mutagenesis. One of several mechanisms of action attributed to aminothiol compounds such as WR-1065 has been their ability to affect endogenous enzymatic reactions involved in DNA synthesis and repair and progression of cells through the phases of the cell cycle. These results are consistent with such a proposed mechanism and demonstrate in particular a modifying effect by WR-1065 on Topo II, which is involved in DNA synthesis.

As the valence of these Period V cations increases, the cation tends to form silicate species that are depolymerized relative to the species dominating the structure of the glass. The dominant species are those with 0 or 1 non-bridging oxygen in all glasses. K (super +) shares NBO with Rb or Sr, there is little sharing of NBO by K and Y, and K and Zr share the same NBO in an apparently nearly fixed bulk stoichiometric K:Zr ratio of 2:1, explaining the increase in ZrO (sub 2) in peralkaline liquids. Predictions are made on the coordination of numbers of cations in silicate liquids and on the possibility of being affected by other cations.

AN - 76420170; 8146273 AB - A polymerase chain reaction (PCR) technique has been developed to detect deletions in the mouse retinoblastoma gene using histological sections from radiation-induced and spontaneous tumors as the DNA source. Six mouse Rb gene exon fragments were amplified in a 40-cycle, 3-temperature PCR protocol. The absence of any of these fragments relative to control PCR products on a Southern blot indicated a deletion of that portion of the mouse Rb gene. Tumors chosen for analysis were lung adenocarcinomas that were judged to be the cause of death. Spontaneous tumors as well as those from irradiated mice (5.69 Gy 60Co gamma rays or 0.6 Gy JANUS neutrons, which have been found to have approximately equal radiobiological effectiveness) were analyzed for mouse Rb deletions. Tumors in 6 neutron-irradiated mice had no mouse Rb deletions. However, 1 of 6 tumors from gamma-irradiated mice (17%) and 6 of 18 spontaneous tumors from unirradiated mice (33%) showed a deletion in one or both mouse Rb alleles. All deletions detected were in the 5' region of the mouse Rb gene.

Here, it is argued that discoveries are often made by a pattern recognition process. Discovery also includes the elaboration of a perceived so that it may be communicated & tested. This elaboration involves development of a descriptive vocabulary, elucidation of mathematical relations & measures, development of instruments & techniques for measurement, & deduction of testable hypotheses. Thus, discovery as a process can be very elaborate & prolonged, & should be amenable to explicit study. Implications for scientific policy & practice are discussed. 14 References.

The success of scientific projects involves both the skill level (creativity) & the number of critical path steps. The lifetime publication rates of most creative/prolific/highly skilled scientists are less productive due to constraints of time-consuming problems. Average scientists with lower skill levels produce more scientific output; but as creativity eliminates problem steps, productivity is enhanced. If observational skill is critical to the project, creativity may have no effect. The scientific productivity model can incorporate sociological factors, & provides a means to test scientific diaries, contructing time budgets & analyzing failures of current projects. 2 Tables, 1 Figure, 29 References.

These models are based on the existing RESRAD code, although each has a separate design and serves different objectives. Two such codes are RESRAD-BUILD and RESRAD-PROBABILISTIC. The RESRAD code was originally developed to implement the US Department of Energy's (DOE's) residual radioactive materials guidelines for contaminated soils. RESRAD has been successfully used by DOE and its contractors to assess health risks and develop cleanup criteria for several sites selected for cleanup or restoration programs. RESRAD-BUILD analyzes human health risks from radioactive releases during decommissioning or rehabilitation of contaminated buildings. Risks to workers are assessed for dismantling activities; risks to the public are assessed for occupancy. RESRAD-BUILD is based on a room compartmental model analyzing the effects on room air quality of contaminant emission and resuspension (as well as radon emanation), the external radiation pathway, and other exposure pathways. RESRAD-PROBABILISTIC, currently under development, is intended to perform uncertainty analysis for RESRAD by using the Monte Carlo approach based on the Latin-Hypercube sampling scheme. The codes being developed at ANL are tailored to meet a specific objective of human health risk assessment and require specific parameter definition and data gathering. The combined capabilities of these codes satisfy various risk assessment requirements in environmental restoration and remediation activities.

Two mechanical models are developed herein; one is for rigid tanks and the other for flexible tanks. The model for rigid tanks has a rigidly attached mass and infinite number of elastically supported masses. The rigid attached mass which possesses a mass moment of inertia represents the impulsive component, whereas the elastically supported masses which do not possess mass moment of inertia represent the convective component of the response. These masses and their heights are chosen such that, under the same base motions, the base shear and base moments of the model match those of the original liquid-tank system. The spring stiffness constants for the elastically supported masses in the model are determined from the sloshing frequencies of the liquid-tank system. The model for flexible tanks, however, only represents the impulsive action of the hydrodynamic response. It has an elastically supported mass that does not possess mass moment of inertia and a member that has no mass but possesses a mass moment of inertia. This latter model is proposed for the study of the effect of the soil-structure interaction.

The tanks considered are the upright circular cylindrical tanks that are rigidly supported at the base. the top of the tanks are either free or constrained. Two types of constraints are considered, namely, hinged and roller support. The governing differential equations for the tank-liquid system are obtained by application of the Rayleigh-Ritz procedure in combination with Lagrange's equation. The response functions examined include the frequency of the fundamental mode of vibration of the tank-liquid system and the associated modal pressure.

The seismic data reveal that rift basins under Lake Superior are variable in depth and are partially filled with Keweenawan age sediments to depths of 7 km or more and volcanic flows to depths of 36 km. These rift basins form a continuous and sinuous feature that widens in the Allouez Basin and Marquette Basin in the western and central lake and narrows between White Ridge and the Porcupine Mountains. The rift basin bends southeast around the Keweenaw Peninsula, widens to about 100 km as it extends into the eastern half of Lake Superior, and exists the lake with its axis in the vicinity of Au Sable Point in Pictured Rocks National Lake Shore, about 50 km northeast of Munising, Michigan. The axis of the rift may exit the western end of the lake near Chequamegon Bay in Wisconsin. However, lack of data in that area limits interpretation at this time. Prior to late-stage reverse-faulting, a continuous basin of more uniform thickness was present beneath the lake. Crustal extension during rifting of approximately 50 km was followed by plate convergence and crustal shortening of approximately 30 km, with the major component of thrust from the southeast. Crustal shortening occurred after development of rift grabens and their filling with lava flows, but before deposition of the final sag basin sediments. Integration of information obtained from outcrops with data reported here indicates that the Lake Superior section of the rift is associated with as many as three major boundary faults.

The quantities examined include the hydrodynamic pressure, base shear and moments. The results are compared with those obtained with no soil-structure interaction. Only the impulsive component of response is examined; the convective component is for all practical purposes unaffected by soil-structure interaction. It is shown that for the conditions considered, soil-structure interaction reduces the peak response of the tank-liquid system.

Both the leachate and the visual appearance of the spent fuel have been characterized for 581 days of testing. The amount of Am and Cm measured in the leachates was one to two orders of magnitude greater than that released from spent fuel under saturated conditions. The cause of this difference has not been firmly identified but may be attributable to the presence of large amounts of actinide-containing colloids in the leachate of the unsaturated tests.

Cleanup of the site is in the planning and design stage, and various engineering activities were considered for remedial action, including excavating soils, dredging sludge, treating various contaminated media in temporary facilities, transporting and staging supplies and contaminated material, and placing waste in an engineered disposal cell. Both contaminated and uncontaminated emissions from these activities were evaluated to assess air quality impacts and potential health effects for workers and the general public during the cleanup period. A site-specific air quality modeling approach was developed to address several complex issues, such as a variety of emission sources, an array of source/receptor configurations, and complicated sequencing/scheduling. This approach can be readily adapted to reflect changes in the expected activities as engineering plans are finalized.

The use of geochemical techniques to determine relationships among aquifers in environmental investigations is limited, in part, because of a generally held view that these techniques may not be useful for shallow aquifers. In this paper, the authors discuss the use of (a) major ion compositions, (b) stable isotope ratios of oxygen, hydrogen, and carbon, and (c) the abundance of tritium to identify multiple aquifers, to establish the lateral extent of aquitards, and to determine hydraulic interconnections among aquifers at two hazardous waste sites. Experience with these and ongoing investigations at several other sites demonstrates that carefully conducted geochemical sampling and analysis of limited samples of groundwater provide an effective tool for hydrogeologic characterization in a variety of geologic settings.

The facility contained 129 cast-iron pipes set vertically in a 21 feet deep concrete monolithic structure. Deterioration of the unit allowed water to enter the pipes, carrying radioactive materials into surrounding soil and groundwater. Radioactive sediment and numerous small metallic objects were found in the pipes. Decontamination was undertaken to remove the radioactive water and sediment. The highly radioactive metallic objects were removed and characterized. Residual radioactivity was removed from the structure by removing each pipe from the concrete matrix through a deep concrete coring operation.

Under the ALARA process, exposures and risks are reduced as far below protective criteria as can reasonably be achieved--considering technical, economic, and social factors. Risk-based cleanup levels have been developed for radionuclides and chemicals in surface water and soil at the Weldon Spring site in Missouri, following explicit applications of the ALARA process. Among the lessons learned during these applications were the importance of three factors: (1) soliciting early input from the parties involved--because the ALARA process involves a range of technical and nontechnical issues; (2) maintaining site specificity for the ALARA analyses--because contaminant types and distributions will vary, as will local conditions and constraints; and (3) identifying cleanup levels in the planning phase that are distinct from those developed for the field phase--because remedies can be over-designed if the decision levels are the same as the ALARA goals for field work, such that little increased risk reduction is achieved for substantially higher costs.

Field experiences, however, indicate that waste containment may be affected by hydrologic conduits around the injection well. To assess the potential effects of these conduits, upward migration of injected waste is examined through the use of numerical models under various conditions. Test results indicate that without any preferential hydrologic conduits, most of the injected waste moves laterally in the injection interval, whereas only a small amount of waste migrates upward into the containment interval. When vertical fractures in the disturbed zone or defects in the cement seal around the wellbore exist, the contaminant can move rapidly upward along these conduits to an overlying aquifer, from which it migrates in the lateral direction. The contamination of the overlying aquifer that results from the upward migration of injected waste through these conduits cannot be impeded by a thick, low-permeability containment interval. However, when permeable interbeds exist within the containment interval, a significant portion of the waste migrating upward can be diverted laterally before reaching the overlying aquifer. The front of built-up pressure can reach the aquifer or permeable interbed immediately overlying the injection interval through the preferential hydrologic conduits shortly after the injection starts, but it cannot move farther upward because of pressure dissipation in the permeable formation. This study suggests that the injected waste has the potential to migrate upward into overlying formations through preferential migration conduits around the wellbore.

The actinides present in the leachate were measured after periods of approximately 60, 120, and 275 days. The vessels were acid stripped after 120 and 275 days. Both colloidal and soluble actinide species were detected in the leachates which had pHs ranging from 4 to 7. Alpha spectroscopy studies of filtered and unfiltered leachates showed that large amounts of actinides may be bound in colloids. The uranium phases identified in the colloids were schoepite and soddyite. The actinide release behavior of the two fuels appears to be different. The ATM-106 fuel began to release actinides later than the ATM-103 fuel, but after 275 days, it had released more. The amount of americium released from the two fuels was a higher percentage of the maximum amount of americium present than was the percentage of the simultaneous amount of uranium released.

Low-level radiological contamination is suspected to have occurred at the yard primarily because of leaks from the cooling tower located in the yard. The CP-5 Reactor was a 5-MW research reactor that operated from 1954 until its shutdown in 1979. The CP-5 yard also stored a number of pieces of scientific equipment that exhibited measurable amounts of radioactivity. The reactor and associated yard area are in the process of being decommissioned. As a preliminary step in this direction, a single exploratory monitoring well was installed in the yard. Levels of hydrogen-3 (tritium) ranged from 6.5 to 15.9 nCi/L, and the level of strontium-90 in groundwater ranged from 1.23 to 3.32 pCi/L. Preliminary characterization included drilling two additional monitoring wells and several soil borings in order to collect sufficient soil and groundwater samples. Samples were analyzed for organic, inorganic, and radiological parameters. Low analytical sensitivity for tritium was emphasized for this project. The RESRAD code was used to convert the radiological results of soil samples into human dosage equivalents.

However, there are situations where the equipment should not be anchored. An unanchored piece of equipment is held to the floor only by the gravitational effect and, in the absence of friction, it could move freely. In the analytical investigation of an unanchored item during a seismic event, there is uncertainty on the proper simulation of the boundary conditions so that the analysis model will have no rigid body motion. Seismic responses of a simple analytical model that is representative of a group of unanchored equipment have been investigated with different sets of simulated boundary conditions. The results show when the main interest of investigation is to the potential for tipping during an earthquake, the case with one of the four supporting pads simply supported, its two neighboring pads constrained against twisting motion, and all pads without vertical displacements yields the most conservative prediction.

Most studies on the microbial metabolism of nitroaromatic compounds used aerobic microorganisms. In most cases no mineralization of nitroaromatics occurs, and only superficial modifications of the structures are reported. However, under anaerobic sulfate-reducing conditions, the nitroaromatic compounds reportedly undergo a series of reductions with the formation of amino compounds. For example, trinitrotoluene under sulfate-reducing conditions is reduced to triaminotoluene by the enzyme nitrite reductase, which is commonly found in many Desulfovibrio spp. The removal of ammonia from triaminotoluene is achieved by reductive deamination catalyzed by the enzyme reductive deaminase, with the production of ammonia and toluene. Some sulfate reducers can metabolize toluene to CO (sub 2) . Similar metabolic processes could be applied to other nitroaromatic compounds like nitrobenzene, nitrobenzoic acids, nitrophenols, and aniline. Many methanogenic bacteria can reduce nitroaromatic compounds to amino compounds.

Nitrogen and carbon were supplemented. The soil slurry was mixed continuously and aerated 10 min/day. Ten percent of the contaminated soil was replaced every week. The 2,4,6-trinitrotoluene (TNT) concentration in soil began to drop after 15 days of treatment, falling to less than 0.5 mg/kg from 7800 mg/kg. Total plate counts in both reactors indicated that the bacterial population was maintained, with an average plate count of about 10 (super 8) CFU/mL. The soil slurry was slightly acidic. In addition to TNT, the slurry reactor also removed the other munitions compounds trinitrobenzene (TNB), 2,4-dinitrotoluene (2,4-DNT), RDX, and HMX. Radiolabeling studies on the reactor biomass showed that 23% of C (super 14) TNT was mineralized, while 27% was used as biomass and 8% was adsorbed on to the soil. The rest of the (super 14) CTNT was accounted for as TNT metabolites. Increasing the frequency of soil replacement from once to two or three times weekly did not affect the TNT removal rates. However, the slurry system showed signs of stress, with highly acidic conditions and low oxygen uptake rates.

These investigations were conducted to provide information for remediation efforts. This technique has been used successfully with uranium-contaminated soils from Fernald, OH, and Portsmouth, OH, thorium-contaminated soil from a plant in Tennessee, plutonium-contamination sand from Johnston Island in the Pacific Ocean, and incinerator ash from Los Alamos, NM. Selecting the most suitable method for cleaning a particular site is difficult if the nature of the contamination is not understood. Microscopic characterization allows the most appropriate method to be selected for removing the contamination and can show the effect a particular method is having on the soil. A method of sample preparation has been developed that allows direct comparison of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, enabling characterization of TEM samples to be more representative of the bulk sample.

The linear and Freundlich isotherm models provided adequate description of the adsorption/desorption behavior. Over the range of EDTA concentrations employed in the study (0.01 to 0.10M), no significant difference in the isotherm parameters was observed as a result of the applied EDTA concentration. The presence of EDTA significantly altered the adsorption/desorption behavior of lead on the soil, resulting in less of the metal being adsorbed. The soil with the higher silt/clay content had a greater amount of lead adsorbed onto it (as compared with the sandy soil).

Derivatives of model output with respect to input are obtained exactly. No intrinsic limits to program length or complexity exist for this procedure. Calculation of derivatives of complex numerical models is required in systems optimization, parameter identification, and systems identification. We report on our experiences with the ADIFOR (Automatic Differentiation of Fortran) tool on a two-dimensional groundwater flow and contaminant transport finite-element model, ISOQUAD, and a three-dimensional contaminant transport finite-element model, TLS3D. Derivative values and computational times for the automatic differentiation procedure axe compared with values obtained from the divided differences and handwritten analytic approaches. We found that the derivative codes generated by ADIFOR provided accurate derivatives and ran significantly faster than divided-differences approximations, typically in a tenth of the CPU time required for the imprecise divided-differences method for both codes. We also comment on the impact of automatic differentiation technology with respect to accelerating the transfer of general techniques developed for using water resource computer models, such as optimal design, sensitivity analysis, and inverse modeling problems to field problems.

A potentially powerful use of the ECPT is the mapping of subsurface hydrostratigraphic features and aquifer piezometric surface(s) by using measurements of pore pressure. Most published studies on the use of the ECPT have been limited to shallow sand-clay sequences and indicate only limited success in hydrogeologic characterization. In this paper, we discuss a method for delineating the depth and thicknesses of unsaturated and saturated zones on the basis of the nature and rate of pore pressure dissipation. We have used this method to depths of 110 ft at several sites underlaid by clay-sand or weathered shale-limestone sequences. The equilibrium pore pressures in the saturated zone should ideally indicate the depth of the water table or aquifer piezometric surface; however, our data indicate that an apparent equilibrium value for pore pressures may be obtained that may be lower or higher than the true value, depending on the composition and grain size of the material in the aquifer, the depth of the dissipation test within the saturated zone, and the history of use of the porous filter in the cone penetrometer assembly. Consequently, the data on dissipation must be carefully calibrated and tested with measurements in a monitoring well before the data are used to determine piezometric surfaces.

Organic geochemical studies conducted on a series of coalified wood samples derived mostly from gymnosperms have allowed the development of a chemical reaction series to characterize the major coalification reactions which lignin, the major coal-producing component of wood, undergoes. These involve mostly hydrolysis of aryl ethers, reduction of alkoxyl side chains, alkylation of reactive aromatic sites, and finally condensation reactions of phenolic moieties. Thus, lignin is transformed to catechol-like structures and these are converted to phenol-like structures. The former reactions are well understood to occur during peatification by the action of microorganisms, but the latter have not been shown to be possible in other than model systems. To demonstrate that the catechol-like structures can be made to evolve to phenol-like structures under natural conditions, we attempted to simulate natural burial processes by artificially coalifying a sample containing mostly catechol-like structures under conditions of hydrous pyrolysis. These conditions did indeed induce transformations of catechol-like structures to phenol-like structures, but the reactions do not reproduce well the coalification reactions with regard to aliphatic structures in coal.

In these tests, glasses produced from SRL 131 and SRL 202 frits were corroded at 90 degrees C in a tuff groundwater. Tests were conducted using crushed glass at different glass surface area-to-solution volume (S/V) ratios to assess the effect of the S/V on the solution chemistry, the corrosion of the glass, and the disposition of actinide elements. Observations regarding the effects of the S/V on the solution chemistry and the corrosion of the glass matrix have been reported previously. This paper highlights the solution analyses performed to assess how the S/V used in a static leach test affects the disposition of actinide elements between fractions that are suspended or dissolved in the solution, and retained by the altered glass or other materials.

Although this correlation can be taken as evidence that CO (sub 2) amplifies orbital forcing of temperature and is thus a strong greenhouse gas, this paper argues that estimating the strength of the CO (sub 2) warming effect from statistical evaluations of past climates based on CO (sub 2) and orbital forcing is hampered by strong multiple correlations between CH (sub 4) , CO (sub 2) , ocean currents, ice volume (and therefore albedo), dust, and nonseasalt sulfate. To estimate the strength of the greenhouse warming effect of CO (sub 2) from historical data, these correlations and multiple forcings should be taken into account.

Only acceptable mud formulations were specified in the permits which approved discharges. Any additional discharges of special additives required separate authorization. Compliance was determined through influent control, documentation and occasional toxicity tests. The approach was successful for the control of the relatively small number of operators off Alaska, but might be difficult to operate without modification in other fields.

A soil bacterial consortium isolated from TNT-contaminated soil was studied for its ability to transform TNT in the presence of different substrates (malic acid, acetate, citrate, sucrose, glucose, succinate, molasses). The specific growth rate of cultures growing on molasses was 3-6 times greater than that of cultures growing on the other substrates. Molasses at 0.3 per cent supported maximal growth. Using this molasses concentration 100 ppm TNT was transformed within 12 h incubation. The major intermediates identified were 4-amino-2,6-dinitrotoluene and its isomer, 2-amino-4,6-dinitrotoluene. Studies with carbon-14 radiolabelled TNT gave no evidence for the mineralization of TNT to carbon dioxide.

N1 - Last updated - 2011-12-12 ER - TY - JOUR T1 - Developments and applications of field mass spectrometers AN - 13665300; S199953292 AB - Applications of gas chromatography-mass spectroscopy (GC-MS) in field analytical methods (FAM) are reviewed. The FAM range from adaptations of accepted laboratory methods to screening methods with cost savings or time savings at the cost of relaxed data quality. The use of FAM is appropriate when the following 4 conditions are met: a suitable FAM is available; the detection limit of the FAM is lower than the regulatory cutoff; the uncertainty of the FAM-derived measurement accounts for less than 25 per cent of the overall multiplicative uncertainty of the site characterization process; and rapid access to the information in making decisions is required. The mass analysers most commonly used in field instruments are the linear quadrupole and the quadrupole ion trap. Commercially available field GC-MS instruments are described: the Mobile Environmental Mass Spectrometer (MEM and EM-640) from Bruker Instruments and the Viking SpectraTrak 620 from Viking Instruments Corporation. The U.S. EPA's thermal chromatography-MS system is described and research into the development of new portable GC-MS systems is outlined. There are 45 references.

According to laboratory studies, the increase in aerosol surface area would lead to a loss of ozone. Radiation measurements from the solar backscatter ultraviolet spectroradiometer are used to probe the absorbing and scattering properties of the stratosphere after the eruption. The backscattered radiation is enhanced for wavelengths greater than 290 nm, with a peak at about 302 nm. The enhancements associated with aerosol backscattering and ozone change can be separated. A decrease in column ozone of 8 to 30 Dobson units was deduced within the aerosol layer at an altitude between 20 and 30 km following the month of the eruption.

AN - 76222188; 8310006 AB - Isolated clones of V79 Chinese hamster lung fibroblasts, selected for resistance against cadmium toxicity, were exposed to monochromatic 365 nm ultraviolet-A (UVA; 320 nm to visible light) radiation and examined for cell survival. All three of the Cd-resistant V79 clones (V79Cd) tested exhibited significant increases in survival after irradiation compared with control cultures similar to the increased survival observed in Zn acetate-induced V79 cells. Dose-modifying factors calculated for these survival experiments were all approximately 1.5. When characterized for steady-state levels of metallothionein (MT) mRNA and associated Cd-binding activity, all of the Cd-resistant V79Cd clones demonstrated elevated constitutive levels of both, implicating MT as the mechanism responsible for the observed cellular resistance to Cd and also to 365 nm UVA radiation. However, whereas levels of intracellular MT protein correlated with differences in survival against Cd, MT intracellular levels did not correlate well with protection against 365 nm UVA. Increased cell survival after exposure to 365 nm UVA radiation mediated by MT appeared to reach a threshold level and MT only provided a limited degree of protection. Since UVA radiation is known to cause cell death mediated through the intracellular generation of reactive oxygen species (ROS), these results suggest that the role of MT in ameliorating cellular photooxidative damage produced by UVA is by reducing intracellular ROS.

DOE sites may have radioactive, hazardous, or mixed contamination. The major contaminants include radionuclides, volatile organic compounds (VOCs), and heavy metals. The contamination exists in soils, groundwater, and buildings and materials. DOE's special problems in site remediation have created a need for better and less costly technologies. Thus, DOE has implemented several initiatives for developing new technologies. This report describes the results of the first set of procurement contracts in this area. Similar research and development (R&D) activities are currently managed for DOE by the Morgantown Energy Technology Center.

AN - 76043515; 8225987 AB - Recently published rates of elimination of radium (in percentage of contemporary body content per year) demonstrated that human radium cases with low body contents lost radium more rapidly than predicted by the ICRP Publication 20 retention equation. In ICRP Publication 20, the apposition and resorption rate in compact bone is defined as 2.5% y-1, but in the derivation of the retention equation for radium a value of only 1.5% y-1 was used. In the present work, the retention equation was reevaluated by using the rate of 2.5% y-1. The revised equation was a good fit to the data for measured values of the body content of radium from environmental levels of radium in food and water. The equation also described the observed rate of loss of radium at long times after deposition for radium cases with low measured body burdens.

AN - 76018860; 8105468 AB - In photosynthetic reaction centers, a quinone molecule, QB, is the terminal acceptor in light-induced electron transfer. The protonatable residues Glu-L212 and Asp-L213 have been implicated in the binding of QB and in proton transfer to QB anions generated by electron transfer from the primary quinone QA. Here we report the details of the construction of the Ala-L212/Ala-L213 double mutant strain by site-specific mutagenesis and show that its photosynthetic incompetence is due to an inability to deliver protons to the QB anions. We also report the isolation and biophysical characterization of a collection of revertant and suppressor strains that have regained the photosynthetic phenotype. The compensatory mutations that restore function are diverse and show that neither Glu-L212 nor Asp-L213 is essential for efficient light-induced electron or proton transfer in Rhodobacter capsulatus. Second-site mutations, located within the QB binding pocket or at more distant sites, can compensate for mutations at L212 and L213 to restore photocompetence. Acquisition of a single negatively charged residue (at position L213, across the binding pocket at position L225, or outside the pocket at M43) or loss of a positively charged residue (at position M231) is sufficient to restore proton transfer activity to the complex. The proton transport pathways in the suppressor strains cannot, in principle, be identical to that of the wild type. The apparent mutability of this pathway suggests that the reaction center can serve as a model system to study the structural basis of protein-mediated proton transport.

AN - 76014604; 8210325 AB - The effects of exposure to 60Co gamma rays for the duration of life on mortality patterns in beagles were investigated. Doses of 3, 7.5, 18.8, 37.5, 75, 127.5, 262.5, 375, or 540 mGy were delivered over a 22-h day 7 days a week. Hazard models with time-dependent covariates were used to identify radiation-related trends in mortality. Hematopoietic failure occurring early in life was positively associated with the accumulated dose and the rate at which the dose was delivered. The risk of death from causes other than cancer that occurred later in the life span also depended on accumulating dose and dose rate but was lower than the cancer risk. Once an animal survived long enough to die from cancer, failure times depended only on the accumulating dose. The slope 1 and slope 2 boundary in a Gompertz plot historically used to identify the transition between dose rate and total dose effects was also found to distinguish between late-occurring deaths associated with tumor or nontumor events.

It describes the analysis and models used to derive site-specific guidelines for allowable residual concentrations of radionuclides in soil and the design and use of the RESRAD computer code for calculating doses, risks, and guideline values. It also describes procedures for implementing DOE policy for reducing residual radioactivity to levels that are as low as reasonably achievable. Two new pathways, radon inhalation and soil ingestion, have been added to RESRAD. Twenty-seven new radionuclides have also been added, and the cutoff half-life for associated radionuclides has been reduced to six months. Other major improvements to the RESRAD code include the ability to run sensitivity analyses, the addition of graphical output, user-specified dose factors, updated databases, an improved groundwater transport model, optional input of a groundwater concentration and a solubility constant, special models for tritium and carbon-14, calculation of cancer incidence risk, and the use of a mouse with menus.

The SEPs are environmental activities a company negotiates with EPA in exchange for a reduced fine. Although the cost of implementing an SEP can be more than the reduction in a fine a SEP can be economically advantageous: (1) through savings in process changes that decrease wastes; (2) tax incentives; and (3) decreased transaction costs due to decreased legal fees.

The pristine calcite surface in contact with the N (sub 2) has an interfacial width of 2.60 +- 0.15 Angstrom . Exposure to humid N (sub 2) caused a water film deposition 19.9 +- 0.4 Angstrom thick with no apparent roughening of the calcite surface. Exposure to deionized H (sub 2) O caused roughening of the calcite with an interfacial width of 23.1 Angstrom . The results indicate that intra-terrace areas participate in the dissolution of calcite.

AN - 75891459; 8360298 AB - A high-throughput liquid-absorption preconcentrator (HTLAP) for rapid and/or ultrasensitive detection and analysis of trace contaminants samples air at a rate of 600-700 l/min and collects analytes from vapors or aerosols at an efficiency of 40-60% into a small volume of liquid absorbent dripping at a rate of 0.1-2 ml/min. These features combine to reduce the lower detection limit (LDL) of available analytical instrumentation by a factor of > 1000 and/or to permit faster sampling and far more rapid on-site air monitoring than were previously practicable. LDLs of ca. 1:10(13) (v/v) of alkaloids have been achieved with LC and electrochemical detection. The HTLAP is directly adaptable to most liquid-phase analyzers. The small rate of liquid collection is also compatible with available interfaces to mass spectrometers. Moreover, the HTLAP permits detection and quantitation of polar or highly reactive compounds that cannot be readily analyzed by conventional preconcentration and GC.

Methane clathrates and natural gas could have contributed to CO (sub 2) increases at the ends of the last two glacial periods. Computations indicate that oxidation of CH (sub 4) to CO (sub 2) could have rapidly provided enough CO (sub 2) to cause historical CO (sub 2) changes. A simple dynamic model, the hydrocarbon pump, for methane as the source term for changes in CO (sub 2) over the glacial cycles matches several features of the historical record. If methane clathrates were the source of CO (sub 2) , then CO (sub 2) at the interglacial transitions should be depleted in (super 14) C because of the low (super 14) C levels in C from this source. Evidence is presented that this is the case. (super 13) C data are also evaluated. Overall, CH (sub 4) is a credible source for CO (sub 2) , but definitive conclusions await further data.

AN - 75786818; 8511792 AB - To clarify the mechanism of the effect of Cd on bone, virgin female mice with 45Ca prelabeled skeletons (15 microCi/mouse) were exposed to a Ca-deficient diet (0.002%) containing 0, 5, or 25 ppm Cd or 25 ppm Pb for 32 days. During the first 72 hr, the 0 ppm controls showed a 2.5-fold decrease in fecal 45Ca excretion (decreased bone resorption), a 12-fold decrease in total fecal stable Ca, a 5-fold decrease in endogenous fecal Ca excretion, and a significant elevation in both serum 45Ca (108%) and specific activity (92%) due to the Ca-deficient diet. In contrast, Cd immediately and significantly increased fecal 45Ca excretion (55%), total fecal stable Ca (13%), endogenous fecal Ca excretion (32%), as well as serum 45Ca (15%) and specific activity (17%) (25 ppm Cd vs 0 ppm), supporting the hypothesis of an early, direct effect of Cd on bone. Overall, during 32 days, Cd at 25 ppm induced a 60% increase in fecal 45Ca excretion compared to 0 ppm controls, providing a sensitive measure of the Cd-induced increase in bone resorption. In contrast, the effect of Cd was too small to cause a statistically significant 45Ca loss from the right femur and lumbar vertebrae, but a significant 45Ca loss (up to -13%) was seen for the remaining skeleton (25 ppm vs 0 ppm group). In addition, Cd at 25 ppm induced small but statistically significant decreases in ash weight (-12%), ash weight to dry weight (-5%), Ca/dry (-7%), and Ca/ash (-2%) in the right femur and significant decreases in ash/dry (-7%) and Ca/dry (-12%) in the lumbar vertebrae compared with the controls. Our present study supports the hypothesis that Cd at 25 ppm had a significant direct effect on bone, with no effect at 5 ppm Cd or 25 ppm Pb, and no appearance of the extreme demineralization characteristic of Itai-Itai disease, although mice were exposed to a Ca-deficient diet for 32 days. Our results from this and earlier studies support the view that chronic Cd exposure along with nutritional deficiency contributed to the pathogenesis of Itai-Itai disease among multiparous, postmenopausal women in Japan.

Differential preclinical responses of irradiated female dogs in progression to either aplastic anemia or myeloproliferative disease. AN - 75763201; 8501968 AB - Female beagle dogs were chronically exposed to low daily doses of 60Co gamma rays (7.5 cGy day-1) and responded in one of three distinct hemopathological patterns. These patterns, reflective of distinct subgroups, were characterized by (a) low radioresistance resulting in progressive hematopoietic suppression, terminal aplastic anemia (AA), and relatively short (< 400 days) survival (-S-AA subgroup); (b) high radioresistance, initially coupled with strong but aberrant regenerative hematopoiesis, and later with the development of myeloproliferative disease (MPD) ((+)-R-MPD subgroup); and (c) high radioresistance, coupled with an early phase of strong regenerative hematopoiesis, but later with no myeloproliferative disease (+R-nonMPD subgroup). In this study, the changes in circulating blood cell levels (granulocytes, monocytes, erythrocytes, lymphocytes and platelets) were sequentially assessed in time and fitted to a flexible, quadratic-linear-type response model previously developed. These analyses provided definition to (a) an initial suppressive, radiotoxic phase and (b) the subsequent recovery phase for each of these subgroups. The magnitude and severity of blood cell loss during the initial suppressive phase was generally greatest in the -S-AA subgroup and lowest in the +R-nonMPD subgroup, with the +R-MPD subgroup showing intermediate level responses. A notable exception included a very high net loss of blood granulocytes by the +R-nonMPD subgroup relative to the other two subgroups. By contrast, the magnitude of blood cell restoration, as well as blood cell maintenance levels during the secondary, recovery phase, was generally highest in the +R-MPD subgroup, of intermediate strength in the +R-nonMPD subgroup, and extremely weak or absent in the -S-AA subgroup. Notable exceptions were in the +R-nonMPD subgroup's high recovery rates of monocyte and lymphocyte blood levels, as well as the high maintenance levels of blood granulocytes during recovery. These results are consistent with our earlier observations of blood responses of chronically irradiated male dogs, in that subgroups of female dogs prone to specific radiogenic hematopathologies (i.e. AA and MPD) can be readily identified and staged in specific preclinical periods by a series of marked differential blood responses.

Hot gas discharges from fumaroles in and around the summit crater, and thermal waters discharge from three areas on its flanks. The waters from all areas have deltaD values of -75 +- 1, indicating a single recharge area high on the volcano. Air- corrected values of (super 3) He/ (super 4) He in thermal wters are 3.8- 6.7 R (sub A) , approaching those for crater fumarole gas (6.1-7.1 R (sub A) ) and indicating widespread addition of magmatic volatiles. An economic S deposit (El Vinagre) is being mined in a fault zone at 3600 m height. The S isotopic data are consistent with a magmatic origin for S species in thermal waters and gases, and for the S ore deposit. Isotopic equilibration between S species may have occurred at 220 +- 40 degrees C, which overlaps possible equilibration T (170 +- 40 degrees C) determined by a variety of other geothermometers for neutral thermal waters. Apparent CH (sub 4) -CO (sub 2) equilibration T for gases from thermal springs (400 +- 50 degrees C) and crater fumaroles (520 +- 60 degrees C) reflect higher T deeper in the system. Hot magmatic gas ascending throughthe Rio Vinagre fault zone is thought to have precipitated S and generated thermal waters by interaction with descending meteoric waters.

AN - 75638343; 8452876 AB - The patterns of glycosphingolipids (GSLs) were analyzed in an HL-60 cell variant, HL-205, which is susceptible to phorbol 12-myristate 13-acetate (PMA)-induced monocyte/macrophage differentiation, and in an HL-60 cell variant, HL-525, which is resistant to such differentiation. The amounts and types of the GSLs were similar in both the HL-205 and HL-525 cells and they resemble those of granulocytes. Treatment with 3 nM PMA caused the susceptible HL-205 cells (but not the resistant cells) to acquire a new GSL pattern which resembles that of monocytes. This new pattern was characterized by increases in the level of a neutral GSL, Gb3Cer, from trace levels to 0.05 mg/10(9) cells and of an acidic GSL, GM3 ganglioside, from 0.03 to 0.33 mg/10(9) cells. The increases in the level of this ganglioside were found to be due to an increase in CMP-N-acetylneuraminic acid:lactosylceramide sialyltransferase activity. These results indicate an association between PMA-induced terminal differentiation along the monocyte/macrophage cell lineage and PMA-evoked increases in specific GSLs, GM3 in particular, which is due to a rise in the activity of its synthetic enzyme.

AN - 75660466; 8464379 AB - The Chinese hamster ovary (CHO) cell line xrs-5 is a radiation-sensitive mutant isolated from CHO-K1 cells. The radiation sensitivity is associated with a defect in DNA double-strand break rejoining. Chromatin structure also appears altered in xrs-5 cells compared with the parental CHO-K1 cells. Metaphase chromosomes from xrs-5 are more condensed in appearance than CHO-K1 chromosomes. The overcondensed look is not the result of colcemid sensitivity. Electron microscopy studies suggest that xrs-5 metaphase chromosomes have larger loops of chromatin extending out from the chromosome core. There are also differences between CHO-K1 and xrs-5 cells in the size and fluorescence pattern of ethidium bromide-stained nucleoid preparations. These results suggest that there is a fundamental difference between CHO-K1 and xrs-5 in either the organization of the supercoiled loops of DNA attached to the nuclear matrix or in the nature of the proteins that attach the DNA to the matrix. These alterations in chromosome structure may underlie, in part, the radiation sensitivity of xrs-5 cells.

The ages and hot-spring activity correspond with periods of high lake- levels within the rift over the past 200 000 yr. The results suggest that the raised water table and increased availability of meteoric water associated with more humid climates can promote greater transfer of heat and mass from deep, long-lived sources, to thesurface. This correlation of humid climate with ages of preserved geothermal SiO (sub 2) deposits is regarded as significant.

Ra contents correlate positively with the solubilities of baryte, anhydrite and calcite at aquifer T. Waters undersaturated with baryte at these T occur only in the Upper Geyser Basin where an altered vitrophyric rhyolite aquifer contains abundant zeolites. The [Ra/Ba] and ( (super 228) Ra/ (super 226) Ra) values of the waters are related to the respective U/Ba and Th/U ratios of the aquifer rocks. These ratios are modelled, and the application of Ra isotopes to geothermal studies, discussed.

This paper reviews how natural and historical synthesized glasses can be employed as natural analogues for understanding and projecting the long-term alteration of high-level nuclear waste glasses. The corrosion of basaltic glass results in many of the same alteration features found in laboratory testing of the corrosion of high-level radioactive waste glasses. Evidence has also been found indicating similarities in the rate controlling processes, such as the effects of silica concentration on corrosion in groundwater and in laboratory leachates. Naturally altered rhyolitic glasses and tektites provide additional evidence that can be used to constrain estimates of long-term waste glass alteration. When reacted under conditions where water is plentiful, the corrosion for these glasses is dominated by network hydrolysis, while the corrosion is dominated by molecular water diffusion and secondary mineral formation under conditions where water contact is intermittent or where water is relatively scarce. Synthesized glasses that have been naturally altered result in alkali-depleted alteration features that are similar to those found for natural glasses and for nuclear waste glasses. The characteristics of these alteration features appear to be dependent on the alteration conditions which affect the dominant reaction processes during weathering. In all cases, care must be taken to ensure that the information being provided by natural analogues is related to nuclear waste glass corrosion in a clear and meaningful way.

Conventional trench-and-fill construction techniques were employed for all four sites. Estimated areal coverage of each species by vegetative strata within transect plots was recorded for plots on the ROW and in immediately adjacent wetlands undisturbed by construction activities. Relative success of regeneration was measured by percent exposed soil, species diversity, presence of native and introduced species, and hydric characteristics of the vegetation. Variable site factors included separation and replacement of topsoil, final grading of the soil, application of seed and fertilizer, and human disturbance unrelated to construction. Successful regeneration exhibited greater dependency on the first three factors listed.

The actinides present in the leachate were determined at the end of two successive periods of approximately 60 days and after an acid strip done at the end of the second period. Both colloidal and soluble actinide species were detected in the leachates which had pHs ranging from 4 to 7. The uranium phases identified in the colloids were schoepite and soddyite. In addition, the actinide release behavior of the two fuels appeared to be different for both the total amount of material released and the relative amount of each isotope released. This paper will focus on the detection and identification of the colloidal species observed in the leachate that was collected after each of the first two successive testing periods of approximately 60 days each. In addition, preliminary values for the total actinide release for these two periods are reported.

Half of the tests used actinide and Tc-99 doped glass and were exposed to an external ionizing gamma source, while the remaining glass samples were doped only with uranium and were reacted without any external radiation exposure. The effects of radiation exposure on glass alteration and secondary phase formation were determined by comparing the reaction rates and mineral paragenesis of the two sets of samples. All glass samples readily reacted with the water that condensed on their surfaces, producing a smectite clay layer within the first three days of testing. Additional crystalline phases precipitated on the altered glass surface with increasing reaction times, including zeolites, smectite, calcium and sodium silicates, phosphates, evaporitic salts, and uranyl silicates. Similar phases were produced on both the nonirradiated and irradiated samples; however, the quantity of precipitates was increased and the rate of paragenetic sequence development was accelerated in the latter. After 56 days of testing, the smectite layer developed at an average rate of (approximately)0.16 and 0.63 mu m/day for the nonirradiated and irradiated samples, respectively. These comparisons indicate that layer development is accelerated approximately four-fold due to the radiation exposure at high glass surface area/liquid volume (SA/V) conditions. This increase apparently occurs in response to the rapid concentration of radiolytic products, including nitric acid, in the thin films of water contacting the sample monoliths.

Attempts to describe these relationships at larger scales or in complex landscapes have been hampered by the lack of spatially explicit distributed parameter models linked dynamically to geographical information systems (GIS). This paper describes developments we have made to link such models to GIS and to develop visualization methods (a graphical interface) that permits the user to readily manipulate large element files containing model parameters. We then present preliminary results illustrating the effects of pattern (in an agricultural landscape) on water and material flow across a heterogeneous landscape composed of multiple watersheds. These dynamics are driven in large measure by the location, size, and number of forest patches. By use of soil, hydrologic, and vegetation data from a real landscape, the effects of spatial relocation of vegetation on water and sediment dynamics are explored through the model-GIS combination. The spatiotemporal modeling approach described here could be useful in effectively managing ecosystem restoration and rehabilitation at the landscape scale.

A significant cause for wetland loss in this region is relative sea-level rise produced by sediment-volume reduction. Dewatering, grain reorientation and packing, and oxidation of organic-rich sediments are thought to be the main processes for volume loss. It is argued that natural and anthropogenic causes for sediment degasification play a critical role in sediment-volume reduction. Compressional wave velocities were measured at 34 sites in both the abandoned (Holocene) and modern parts of the Mississippi Delta. A low-frequency source (<200 Hz) was used to maximize sound-wave dispersion caused by interstitial gas bubbles. Compressional wave velocities measured at low frequencies relative to the gas-bubble resonant-frequency undergo maximum change from the velocity for a gas-free sediment. Seismic refraction studies and velocity measurements using standard reverse-spread profiling indicate that the upper 40-70 m of the sedimentary section has sound velocities significantly less than the speed of sound through water (1,500 m/s), despite the fact that the water table is within 3 m of the ground surface. The low-velocity zone has average velocities ranging from 800 to 1,150 m/s in the Holocene delta and from 900 to 1,300 m/s in the modern delta. Uphole traveltimes obtained from approximately 90 km of continuous-coverage, seismic reflection profiles yield velocity estimates that range from 900 to 1,300 m/s. First and secondary arrivals determined from the reflection profiles are currently being used to model the low-velocity zone. Theoretical velocity modeling, using material properties consistent with observed sediment types, suggests that approximately 6-20% of the available pore space must be occupied by gas to account for the observed velocities. This gas is believed to be trapped in unconnected pore spaces to exist in the form of methane gas bubbles within the interstitial pore waters. The trapped gas acts to buoy overlying sediment against subsidence. Any quick-release triggering mechanism for the gas, such as trenching, digging canals, or extensive drilling, could cause localized increases in subsidence rates. From an inspection of compressional velocities observed in Holocene sediments in the Louisiana wetlands, a 3- to 4-m drop in elevation would occur if all the gas in a 60-m-thick section were quickly released.

Efficient and innovative data-acquisition procedures are imperative in order to provide complete coverage at a large number of small-sized sites. Because APG is a chemical weapons research and development facility, noninvasive geophysical techniques are a necessity. Real-time data processing and interpretation using computers in a field setting permit rapid changes in the design of the survey and in decision making. Magnetic and electrical interference caused by metal buildings, power lines, and buried utilities limit applicable geophysical techniques. A pilot study to test a variety of techniques resulted in the selection of horizontal electrical resistivity profiling, magnetic gradiometry, total field magnetics, and ground-penetrating radar. A systematic geophysical survey was designed that begins with a continuous-coverage magnetic gradiometer sweep, in conjunction with a gridded survey of the total magnetic field. A finer-spaced, more detailed, total magnetic field survey was then conducted around anomalous areas identified by the gradiometer sweep. Horizontal resistivity surveying followed and provided information on the electrical properties of the subsurface to help identify nonferrous metals and contaminant plumes. A modification of traditional horizontal resistivity profiling was developed to allow rapid and extensive data collection around metal buildings. Ground-penetrating radar helped determine the geometry and the approximate depth of anomalies detected by the magnetic and electrical surveys. The final interpretation depends on separating cultural effects (such as road and construction fill, buildings, buried and overhead utilities) from anomalies that may be potential sources of contamination (such as buried drums, underground storage tanks, pits). Historical aerial photos and utility and site plans are incorporated into the interpretation cycle. Computer software, which superimposes magnetic contours over a color image of the resistivity data was used. This permits the simultaneous interpretation and evaluation of the conductive and magnetic features. Ground-penetrating radar profiles were exported from DOS machines to a Macintosh machine to improve the color graphics and figure labeling. This rapid and flexible approach to a geophysical survey of small sites is still evolving, and techniques are being refined to increase the overall efficiency while retaining data quality and resolution of small anomalies.

The enrichment culture that used nitrate as an electron acceptor removed a significant amount of the TNT, such that 80 per cent of the original 100 ppm concentration was removed within 40 d of incubation. The principal intermediates of TNT degradation were 2-amino-4,6-dinitrotoluene and its isomer 4-amino-2,6-dinitrotoluene. Sulphate reducing and hydrogen:carbon dioxide methanogenic conditions produced a much lower TNT removal efficiency.

A forced gradient was established prior to injection by recirculating water from the withdrawal well to the injection well. Analysis of the water showed that plutonium and americium, associated with low-molecular-weight organic matter, migrated in the aquifer. In addition, naturally occurring uranium, thorium, and radium was dissolved from sandy substrata by these organic components and were also mobilized. The implications for underground storage and containment of low-level radioactive wastes are considered. There are 31 references.

The total effect on the radiation balance will depend on the relative magnitude of these opposing forces, which in turn depends on the composition of the aqueous phase. The infrared band positions and band strengths in aqueous solution have been determined for a representative cross-section of important water-soluble species in the polluted atmosphere, namely sulphate, nitrate, bicarbonate, ammonium, acetate, oxalate, formate, formaldehyde, ethanol, methanol, phenol and p-nitrophenol. Results are tabulated and the relative effect of these ions on radiative forcing are discussed. There are 42 references.

AN - 73431497; 1336363 AB - Okadaic acid (OA), an inhibitor of protein phosphatases 1 and 2A, induces differentiation in human MCF-7, AU-565, and MB-231 breast tumor cells. In MCF-7 cells, OA elicited within 5 min an increase in the levels of a set of phosphorylated cellular proteins, within hours expression of the early response genes junB, c-jun, and c-fos, and within days manifestation of differentiation. Differentiation was also induced by two related protein phosphatase inhibitors, but not by an inactive OA derivative or by an inhibitor that penetrates epithelial cells poorly. These results indicate that OA and related agents can induce tumor breast cell differentiation, and this induction is correlated with their ability to inhibit PPH 1 and 2A.

AN - 73477868; 1286668 AB - Alterations in the abundance or structure of mouse liver proteins are being studied using two-dimensional gel electrophoresis (2-DE) to build a database of protein changes correlating with exposure to ionizing radiation or toxic chemicals. Thus far, studies have included the analysis of proteins from the offspring of exposed parents or from the exposed individuals themselves. In order to characterize and identify proteins found altered by such exposures, sex- and strain-related differences in protein patterns have been analyzed, and the subcellular locations of a large portion of the mapped proteins have been determined. As part of these studies, data are collected and stored using a variety of computer hardware and software tools that allow the accumulation of information on the origin of samples, gel identification, experiment description, and protein similarities and differences. This accumulation of information constitutes the mouse liver protein database. Relational database software is used to tie the different facets of the database together so that the results of a variety of experiments can be compared and interrelated. The database optimizes the information obtained from 2-DE gel sets by allowing use of the data for many purposes, including monitoring of gel resolution to ensure the collection of high quality data and correlation of protein effects induced by different agents. This first edition of the Argonne National Laboratory mouse liver protein database lays the foundation for future work and communication that should elucidate the significance of observed protein effects as possible markers of exposure to toxic agents.

AN - 73378235; 1480112 AB - Cholera and the related Escherichia coli-associated diarrheal disease are important problems confronting Third World nations and any area where water supplies can become contaminated. The disease is extremely debilitating and may be fatal in the absence of treatment. Symptoms are caused by the action of cholera toxin, secreted by the bacterium Vibrio cholerae, or by a closely related heat-labile enterotoxin, produced by Escherichia coli, that causes a milder, more common traveler's diarrhea. Both toxins bind receptors in intestinal epithelial cells and insert an enzymatic subunit that modifies a G protein associated with the adenylate cyclase complex. The consequent stimulated production of cyclic AMP, or other factors such as increased synthesis of prostaglandins by intoxicated cells, initiates a metabolic cascade that results in the excessive secretion of fluid and electrolytes characteristic of the disease. The toxins have a very high degree of structural and functional homology and may be evolutionarily related. Several effective new vaccine formulations have been developed and tested, and a growing family of endogenous cofactors is being discovered in eukaryotic cells. The recent elucidation of the three-dimensional structure of the heat-labile enterotoxin has provided an opportunity to examine and compare the correlations between structure and function of the two toxins. This information may improve our understanding of the disease process itself, as well as illuminate the role of the toxin in studies of signal transduction and G-protein function.

AN - 73293233; 1330653 AB - Treatment of human K-562-J leukemia cells for 1 h with the topoisomerase II-reactive drugs VP-16, VM-26, or mAMSA resulted in a dose-dependent inhibition of proliferation and in an increase in the percentage of cells staining positive for hemoglobin, a marker of erythroid differentiation. Staining for hemoglobin of up to about 60% of the cells was observed at 20 microM VP-16, 1 microM VM-26, and 8 microM mAMSA. Such treatment also caused a G2/M arrest in the cell cycle. Incubation of the cells with radiolabeled VP-16 indicated that the induced erythroid differentiation was not due to continuous cell exposure to a residual amount of the drug. VP-16-induced erythroid differentiation was also not affected by DNA, RNA, or protein synthesis inhibitors. Differentiation induction and the G2/M arrest evoked by VP-16, VM-26, and mAMSA were, however, reduced in the presence of novobiocin. Our results indicate that topo-reactive drugs that cause G2/M arrest in the K-562-J cell cycle can induce in these cells erythroid differentiation after a short and irreversible interaction with their target molecule(s).

Twenty-two surface flux stations at 20 sites were deployed during the four 1987 intensive field campaigns (IFCs). Flux variability is addressed together with the problem of scaling up to area-averaged fluxes. Successful parameterization of area-averaged fluxes in atmospheric models is based on accounting for internal spatial and temporal scales correctly. Mean and variance properties of fluxes are examined in both daily and diurnally averaged frameworks. Results are compared and contrasted for clear and cloudy situations and checked for the influence of surface-induced biophysical controls (burn and grazing treatments) and topographic controls (slope factors and aspect ratios). Examination of the sensitivity of domain-averaged fluxes to different averaging procedures demonstrates that this may be an important consideration. The results reveal six key features of the 1987 surface fluxes: (1) cloudiness variability and ample rainfall throughout the growing season led to near-consistency in flux magnitudes during the first three IFCs; (2) burn treatment, grazing conditions, and topography have clearly delineated influences on the diurnal cycle flux amplitudes but do not alter the evaporative fraction significantly; (3) cloudiness is the major control on flux variability in terms of both mean and variance properties but has little impact on the Bowen ratio or evaporative fraction; (4) spatial weighting of fluxes based on a biophysicaltopographical cross stratification generates a measurable bias with respect to straight arithmetic averaging (up to 20 W m (super -2) in available heating); (5) structure function analysis demonstrates significant underlying spatial autocorrelation structure in the fluxes, but the observed distance dependence is due to cloudiness controls, not surface controls; (6) Monte Carlo analysis of high resolution vegetation indices obtained from SPOT satellite measurements suggest that the mean domain amplitudes of the diurnal sensible and latent heat flux cycles can be biased up to 30-40 W m (super -2) by repositioning the 20 site locations within the experimental domain.

In 1989, 13 sites were instrumented. A variety of sensors were employed to calculate the fluxes of mass and energy. An effort was made throughout the FIFE campaign to compare sensors. A series of papers in this special issue present these group studies and efforts. These papers principally report the 1987 campaign, although two papers report station intercomparison during 1989. Additional papers examine the time-space variability of heat, moisture, and momentum fluxes, as well as analyses of the properties of the CO (sub 2) fluxes and their relationships to water stress. In this overview paper we describe the basic methodologies of the measurements, provide details on the sensor systems used by members of the Surface Flux Group, and provide a summary of the flux articles appearing in this special issue.

AN - 73348858; 1445803 AB - To study the signal transduction pathway leading to phorbol 12-myristate 13-acetate (PMA)-induced differentiation in human promyelocytic HL-60 leukemia cells, we examined the expression of protein kinase C (PKC) isozyme genes in HL-60 cells that are susceptible or resistant to PMA-induced differentiation. The PKC-alpha, -beta, -gamma, -delta, epsilon, and -zeta transcript levels were assessed by Northern blotting, and the PKC-alpha, -beta, and -gamma protein levels were examined by immunoblotting. The PMA-resistant cell variants HL-525 and HL-534 were found to be deficient in the PKC-beta isozyme RNA and protein as compared with the PMA-susceptible HL-60 and HL-205 cell lines. In addition, a "delta-like" PKC RNA species identified in these cells demonstrated a reduced abundance in the HL-525 and HL-534 cells. Southern blot analysis indicated that the observed reduction in PKC-beta gene expression does not appear to be due to a gross deletion or rearrangement of the gene. The expression of the early response genes junB, c-fos, and c-jun was attenuated in PMA-treated HL-525 and HL-534 cells as compared to the PMA-treated HL-60 and HL-205 cells. These results suggest that the signal transduction pathway that leads to PMA-induced differentiation in the HL-60 cell system requires PKC-beta and/or delta-like PKC for the proper expression of the early response genes, and ultimately the expression of genes that define the mature state.

B and Li analyses are also listed for other rhyolitic glasses and waters from a wide range of environments. The results show that B is released during aqueous alteration of the Yellowstone rhyolitic glasses, but Gd and Sm behave more conservatively. Thermal waters associated with these rocks acquire B and Li; Li is preferentially trapped in illitic alteration products. Similar interpretations are applied to rhyolites and waters from the Valles caldera and the Inyo domes chain. Thermal waters associated with the lavas at all three locations show B-Li abundances in the range of other natural waters which approximate a linear relation with B/Li approx 4. In petrogenesis with no hydrous phase, Sm-Gd-B-Li are incompatible, but when an aqueous phase is present, B and Li behave independently of Sm and Gd.

AN - 73219287; 1399620 AB - The statistical distribution of 222Rn measurements from basements and first floors of homes in northeastern Pennsylvania was investigated. The gamma distribution was statistically significantly superior to the normal distribution (p less than 0.005) in describing the frequency distribution of the logarithm of observed 222Rn levels. The fit to the data was closer both in the central portion and in the upper tail. The gamma distribution has certain characteristics that make it generally useful in the study of environmental toxic agents where several different exposures over a lifetime occur and must be combined, as for risk assessment or for statistical power calculations for epidemiologic studies.

AN - 73184845; 1522006 AB - We analyzed six different tissue DNA samples from a leukemic individual who received an injection of Thorotrast for alterations in proto-oncogene or tumor-suppressor gene structure. Our examination of the DNA indicated an alteration of the c-fms gene in the blood sample from this individual. This locus showed a deletion in which the 3' end of the deleted region maps between exons 11 and 12. In this particular case, the type of leukemia is unknown but myeloid leukemia is a neoplasm associated with individuals injected with Thorotrast. It is possible that the alteration in the c-fms gene of this individual is a consequence of the radiation exposure. No apparent alterations in the c-mos gene were observed in any of the tissues from the individual. This is in contrast to previous studies that described alterations in methylation patterns associated with the c-mos locus in radium-exposed individuals. A number of the individuals exposed to radium also had alterations of the retinoblastoma gene while no such alterations were observed in any tissue DNA samples from this Thorotrast case. It is possible that our inability to detect alterations of the c-mos and retinoblastoma gene may be attributable to the nature of alpha-emitting radionuclides or their distribution, or to the limited set of tissues available for analysis.

AN - 73022230; 1615290 AB - A second follow-up of mortality was carried out for workers employed in a thorium-processing plant between 1915 and 1973. The study group comprised 3796 workers (3119 men and 677 women). Of the whole group, 926 (761 men and 165 women) were deceased and 2620 (2161 men and 459 women) were still alive, while 250 (6.6%) were lost to follow-up. For the male workers, the standardized mortality ratio (SMR) for all causes of death was 1.12 with a 95% confidence interval (95% CI) of 1.05-1.21. The SMR for the male workers was also significantly increased for all cancers (SMR 1.23, 95% CI 1.04-1.43) and lung cancer (SMR 1.36, 95% CI 1.02-1.78). For the female workers, the SMR was 0.74 (95% CI 0.63-0.86) for all causes and 0.53 (95% CI 0.35-0.78) for all cancers. The results of a Poisson regression analysis showed that there was no significant effect of the selected factors on lung cancer mortality.

AN - 72971364; 1594760 AB - Many studies have shown the importance of altered cellular proto-oncogene expression in contributing to changes in cell survival, cell transformation, and cell cycle progression. In these experiments we examined the effects of total-body exposure of BCF1 mice to gamma rays (3 Gy) in modulating expression of cellular oncogenes in both gut and liver tissues. We selected specific cellular oncogenes (c-fos, c-myc, c-src, and c-H-ras), based on their normal expression in liver and gut tissues from untreated mice. As early as 5 min following whole-body exposure of BCF1 mice to gamma rays we detected induction of mRNA specific for c-src and c-H-ras in both liver and gut tissues. Accumulation of c-fos-RNA was slightly decreased in gut but was unaffected in liver tissue from irradiated mice relative to untreated controls. Accumulation of c-myc mRNA was unaffected in all tissues examined. These experiments document that modulation of cellular proto-oncogene expression can occur as an early event in tissues following irradiation and suggest that this modulation may play a role in radiation-induced cellular changes.

AN - 72955773; 1316813 AB - An in vitro T-lymphocyte cloning technique has been applied to study the effects of JANUS fission-spectrum neutron irradiation and the radioprotector S-2-(3-aminopropylamino) ethylphosphorothioic acid (WR-2721) on the subsequent development of somatic mutations at the hypoxanthine-guanine phosphoribosyl transferase (hprt) locus in hybrid B6CF1 male mice. In control studies performed to establish an in vitro cloning technique, the mutant frequencies of splenic T-lymphocytes, as a result of exposure to a 100 cGy dose of neutrons, increased with time from a control level of 9 x 10(-7) to a maximum value of 1.7 x 10(-5) at 56 days following irradiation. Between 56 and 150 days after irradiation, mutant frequencies were observed to plateau and remain stable. All subsequent determinations were performed at 56 days following the experimental treatment of animals. WR-2721 at a dose of 400 mg/kg was effective in protecting against the induction of hprt mutants (i.e. a mutant frequency reduction factor, MFRF) following the largest dose of neutrons used (i.e. 150 cGy), whether it was administered i.p. 30 min before, 5 min after, 3 h after, or three times at 3, 24, and 48 h after, as evidenced by MFRFs of 6.0, 6.6, 4.8 and 5.8 respectively. The antimutagenic effectiveness of WR-2721 administered 30 min prior to irradiation was unaffected, even when the dose was reduced to 200 mg/kg, MFRF = 7.0; 100 mg/kg, MFRF = 3.8; and 50 mg/kg, MFRF = 8.9. These findings confirm our earlier report using the radioprotector N-(2-mercaptoethyl)-1,3-diaminopropane (WR-1065) under in vitro conditions, and demonstrate that these agents can be used as effective antimutagens even when they are administered up to 3 h following radiation exposure.

AN - 72936689; 1349621 AB - The ability of the compound S-2-(aminopropylamino)ethylphosphorothioic acid, designated WR-2721, to protect against neutron-induced carcinogenesis was investigated. Both sexes of the B6CF1 mouse were injected i.p. with 400 mg/kg of WR-2721 30 min prior to being irradiated by 10 cGy of neutrons. Neoplastic mortality in the groups receiving thiol was either reduced or delayed relative to irradiated mice not given protector. However, the time at which the protective effect of WR-2721 was expressed depended on the sex of the animal. Thiol-related shifts in the time of neoplastic death in females occurred only in the first half of the lifespan. Once a female survived to the mean age at death, no difference in the pattern of mortality could be detected between control and WR-2721-treated mice exposed to neutrons. Irrespective of thiol treatment, the timing of tumour-related death was nearly identical during the first half of life for males exposed to neutrons. In the last half of the lifespan, survival of thiol-protected males was enhanced relative to saline-injected males and even exceeded that observed in the control population.

AN - 72893087; 1561636 AB - The purpose of this study was to evaluate, in an animal whose skeleton is comparable to humans, the combined effects of estrogen depletion and Cd exposure on bone resorption by monitoring skeletal release of 45Ca and to determine whether Cd-induced bone resorption occurred independent of osteotropic hormone changes and renal dysfunction. Cd exposure following ovariectomy or sham surgery was for 7 months: 1 month by oral ingestion of capsules (1, 5, 15, 50 ppm) and 6 months via drinking water (15 ppm). Serum and fecal 45Ca were increased at 1 week following ovariectomy (OV) (54 +/- 9% and 122 +/- 40%, respectively), but this response was attenuated by 2 weeks. Five of seven exposed dogs had increased serum and fecal 45Ca during the 50-ppm Cd capsule period (15-40% and 15-190%, respectively). Serum 45Ca levels in OV/+Cd dogs showed a significant and consistent increase within 1 week of initiating each of three separate Cd.H2O exposure cycles. Blood Cd levels increased over time from 2 to 15 micrograms/l, coinciding with the elevated serum 45Ca concentrations. No correlation was observed between serum 45Ca increases and parathyroid hormone, 1,25-(OH)2-vitamin D, or calcitonin. No effects of ovariectomy and/or Cd were observed in total serum Ca, calciotropic hormone concentrations, serum or urinary phosphorus and creatinine, creatinine clearance, or urinary specific gravity. Urinary Cd concentrations ranged from 7 to 50 micrograms/l in exposed dogs but were not detectable in nonexposed dogs. Urinary protein concentrations showed no differences between groups. Cd increased bone resorption (skeletal 45Ca release) in ovariectomized and sham-operated dogs without renal dysfunction or calciotropic hormone interaction. Based on our results, Cd is an exogenous factor which exacerbates bone mineral loss in postmenopausal osteoporosis.

The model allows for single-component transport in the gas and water phases. The hydrocarbon is assumed to be in specific retention and, therefore, immobile. Partitioning of the hydrocarbon between the oil, water, gas, and soil is developed as rate-limited functions that are incorporated into sink/source terms in the transport equations. The code for the model was developed specifically to investigate in-situ volatilization (ISV) remedial strategies, predict the extent of cleanup from information obtained at a limited number of measurement locations, and to help design ISV remedial systems. Application of the model is demonstrated for a hypothetical one-dimensional ISV system. Part II of this paper will present the analysis of an existing ISV system using the full three-dimensional capability of the model.

AN - 72827405; 1540954 AB - Protracted exposure of dogs to low daily doses of whole-body gamma-radiation (7.5 cGy/day for duration of life) elicits a high incidence of myeloid leukemia or related myeloproliferative disorders. Under such exposure, vital hematopoietic progenitors [granulocyte/monocyte colony-forming units in agar (CFU-GM)] acquire increased radioresistance along with renewed proliferative capacity at an early phase of evolving myeloid leukemia. To further characterize the expression of acquired radioresistance by CFU-GM, we evaluated the effects of various exposure rates, cumulative radiation doses, and times of exposure and postexposure in several groups of long-lived dogs under two conditions of irradiation: (a) continuous, duration-of-life exposures at dose rates of 0.3-7.5 cGy/day; and (b) discontinuous, fraction-of-life exposures at dose rates of 3.8-26.3 cGy/day, with cumulative doses of 450-3458 cGy and postexposure times of 14-4702 days. Results indicated that (a) under protracted continuous irradiation, the degree of radioresistance expressed by CFU-GM in vitro increased markedly in a biphasic pattern with rising daily rates of exposure; (b) under discontinuous, fraction-of-life exposure regimens, elevated levels of radioresistance were expressed and stably maintained by CFU-GM only following large radiation doses accumulated at high dose rates; and (c) with extended postexposure times, the magnitude of expressed radioresistance appeared to wane. These results continue to support the hypothesis that the acquisition of radioresistance and associated repair functions by vital lineage-committed progenitors, under the strong selective and mutagenic pressure of chronic irradiation, is tied temporally and causally to leukemogenic transformation elicited by radiation exposure.

AN - 72826961; 1347072 AB - The antimutagenic effects of the radiation protective agent, S-2-(3-aminopropylamino)ethylphosphorothioic acid (WR-2721), were studied against fission-spectrum-neutron- and 60Co-gamma-ray-induced mutagenesis in mice. Mutagenesis at the hypoxanthine-guanine phosphoribosyl transferase (hprt) locus was measured 56 days following whole-body irradiation with JANUS neutrons (single doses, 50-150 cGy) or 60Co photons (single doses, 250-750 cGy). Splenic T lymphocytes from B6CF1 mice were grown in round-bottomed 96-microwell culture plates with or without the selective agent 6-thioguanine (6-TG). The mutant frequency, as a result of exposure to neutrons or 60Co photons, increased 100-fold with dose. Doses of 150 cGy neutrons and 750 cGy 60Co photons were equally mutagenic. When animals were injected with WR-2721 at a dose of 400 mg/kg body weight, i.p., 30 min before whole-body irradiation with JANUS neutrons or 60Co photons, mutant frequencies were significantly reduced at all radiation doses (i.e. protection factors of 1.4 and 2.4, respectively). Thus, the aminothiols are effective antimutagens. A novel clinical application of these compounds could be in their use to protect against radiation- and/or chemotherapy-induced genotoxic damage to normal cells.

AN - 75536190; 11537016 AB - Two thiophosphoroate compounds WR-2721 and WR-151327 were assessed for their ability to modify the deleterious effects (life shortening and carcinogenesis) of fission-spectrum neutrons (kerma-weighted mean energy of 0.85 MeV) or gamma rays on B6CF1 hybrid mice. Male and female mice, 200 of each sex per experimental group, were irradiated individually at 110 days of age. Radioprotectors (400 mg/kg of WR-2721 or 580 mg/kg of WR-151327) were administered intraperitoneally 30 min prior to irradiation. Neutron doses were 10 cGy or 40 cGy and gamma ray doses were 206 cGy or 417 cGy. Animals were housed five to a cage; cage locations in the holding rooms were randomized by computer. Animals were checked daily and all deceased animals were necropsied. WR-2721 afforded protection against both neutron- and gamma-ray-induced carcinogenesis and subsequent life shortening. Cumulative survival curves for unirradiated mice of either sex were unaffectecd by protectors. WR-2721 protected irradiated groups against life shortening by approximately 10 cGy of neutrons or 100 cGy of gamma rays. WR-151327 was as effective as WR-2721 against neutron irradiation.

AN - 73524374; 1303952 AB - Bone resorption, as measured by release of bone 45Ca, was significantly increased in elderly female beagles within 96 h of exposure to 15 mg/l cadmium in drinking-water. The 45Ca response was greater in ovariectomized animals than in sham-operated controls and was not mediated by changes in calciotropic hormone concentrations. Mean blood cadmium concentrations were 3-8 micrograms/l during the earliest bone resorption response and 13-15 micrograms/l at the end of the study. During seven months of cadmium exposure, bone mineral densities decreased most in the ovariectomized animals exposed to cadmium: -15.4 +/- 4.3% for the tibia distal end and -7.2 +/- 1.2% for the lumbar vertebrae (L2-L4) (mean +/- SE, n = 4). The results indicate that cadmium may act directly on bone and that postmenopausal women exposed to cadmium in industry or via cigarette smoke may be at increased risk of cadmium-induced bone loss. They also support a direct role of cadmium in the etiopathology of itai-itai disease among postmenopausal women in Japan.

AN - 72846869; 1544855 AB - The anti-AIDS agent, AZT (3'-azido-3'-deoxythymidine), is mutagenic in a cultured human hepatoma cell line designated HepG2 at the HGPRT (hypoxanthine-guanine phosphoribosyl transferase) locus. Using an exposure time of 3 hr, the number of mutants per 10(6) surviving cells increased as a function of AZT dose from 125 to 520. Chinese hamster ovary cells, in contrast, are not affected with respect to this endpoint when similar concentrations of AZT are used (i.e., 0.1 to 10 mg/ml). The aminothiol WR-151326 [3-(3-methylaminopropylamino) propanethiol dihydrochloride] was evaluated as a possible antimutagen for use with AZT. At a concentration of 4 mM, WR-151326 was added either concomitantly or following exposure of HepG2 cells to a 5 mg/ml concentration of AZT. Regardless of the treatment condition, WR-151326 was effective in reducing the mutagenic effects of AZT by about a factor of 2. Correcting for background mutations, the mutation frequencies determined were: AZT only for 3 hr, 110 x 10(-6) (S.E.M. +/- 6.0 x 10(-6)); AZT together with WR-151326 for 3 hr, 57 x 10(-6) (S.E.M. +/- 3.0 x 10(-6)); and AZT for 3 hr followed by WR-151326 for 3 hr, 68 x 10(-6) (S.E.M. +/- 5.0 x 10(-6)). This study demonstrates that AZT is mutagenic to a cell line of human origin and that WR-151326 can protect against this mutagenic process.

AN - 72822712; 1540681 AB - Chinese hamster ovary cells in the exponential phase of growth were harvested and separated by the method of centrifugal elutriation into subpopulations enriched with up to 95% G1 phase, 70% S phase and 65% G2 + M phase cells. Cell cycle distributions were routinely monitored by flow cytometry. Following elutriation, aliquots of cells from each of the enriched cell fractions were incubated in the presence or absence of 4 mM of 2-[(aminopropyl)amino] ethanethiol (WR-1065) for 30 min at 37 degrees C. The cells were then irradiated with 60Co gamma-rays or fission-spectrum neutrons from the JANUS research reactor. Both cell killing and mutagenesis were determined. Regardless of the radiation quality used, cells enriched in G1 phase were the most sensitive to radiation-induced mutagenesis at the hypoxanthine-guanine phosphoribosyl transferase locus. The relative magnitude of protection exerted by WR-1065 differed for each of the elutriator separated cell populations. The greatest magnitude of protection, however, was observed for G1-enriched populations, regardless of the radiation quality used or the biological end-point tested.

AN - 72759216; 1728062 AB - Measurement of the radiation sensitivity of chromosomes was used to address the influence of cell cycle distribution and of DNA content and ploidy on radiation responses in seven human squamous cell carcinoma cell lines. The cell lines varied about twofold in DNA content and chromosome number, and the X-ray sensitivities (D0) of the lines ranged from 1.1 to 2.7 Gy. The more resistant cell lines (D0 greater than 1.8 Gy) had faster growth rates and larger proportions of cells in S phase in asynchronous cultures. Aberration frequencies were measured in cells irradiated in G1 and G2 phase. The more resistant lines had fewer induced aberrations in both phases than did sensitive lines, implying that they were more resistant to radiation in both of these cell cycle phases. Therefore, while the larger S-phase population seen in the resistant cell lines probably contributes to the resistant phenotype, it cannot explain all of the intrinsic differences in radiation sensitivity. There was no relationship between DNA content and radiation sensitivity as measured by the cell survival assay or the induction of chromosome aberrations, although cells with larger DNA contents tended to have more chromosome damage per cell at equitoxic doses.

AN - 72755378; 1728054 AB - In the period from 1971 to 1986, both sexes of the B6CF1 (C57BL/6 x BALB/c) mouse were exposed at 110 +/- 7 days of age to single, 24 once-weekly or 60 once-weekly doses of fission neutrons or 60Co gamma rays. A small group of males was also exposed to gamma rays for 22 h/day, 5 days/week, for either 23 or 59 weeks, the elapsed times for the 24 and 60 once-weekly series. All mice were followed for their natural lifetimes. A gross pathology report is available on 32,000 animals, and a histopathology record is available on about 19,000. About 85% died with or from one or more neoplastic diseases. The principal tumors observed at death were of lymphoreticular (45-60%), vascular (20%), or pulmonary (35-50%) origin. From 4 to 10% died with fibrosarcomas, hepatocellular tumors, ovarian tumors, and tumors of the Harderian, adrenal, and pituitary glands. Dose-response equations (linear and linear-quadratic) were fitted to the data for deaths from and occurrences of eight different individual or groups of tumors. Equations were constrained through the control intercepts and fitted separately for the two sexes, the two radiation qualities, and all exposure patterns for the two intervals of 600-799 days and 800-999 days from first exposure. RBE values were derived from the ratios of linear coefficients of dose-response curves. RBE values increased as dose was protracted, largely due to the reduced effectiveness of protracted gamma irradiation; however, about 28% of the increase can be attributed to the increase in neutron-induced injury caused by dose protraction. Highest RBE values were seen for tumors of epithelial tissue origin and the lowest for tumors of connective tissue origin. The range for significant values was from about 2 to over 50. Nonneoplastic diseases accounted for about 5% of all deaths, and 10% were classified as from unknown causes. Neither category responded to differences in radiation quality or exposure patterns.

A numerical analysis yields the "typical" paper, a convenient model that can save authors time & meet the expectations of readers. This typical paper is 2% abstract, 5% introduction, 25% methods & materials, 50% results, 10% discussion, 4% conclusion, & 4% references. Tables & figures account for 30% of the typical article. The average sentence is a little long (24 words), but sentence structure is simple more often than not. The comeback of the first-person pronoun can be a time-saver, & the passive voice need not be avoided. 39 References. Adapted from the source document.

The deposition fields over the lakes and basins were integrated to calculate total deposition leading after adjusting dry deposition to the lakes to take into account the significant lake effects on dry deposition velocities. The modelled estimates were compared with integrated spatial analyses of deposition, and the significance of atmospheric loading was compared with estimates of loading from tributaries and run-off. The model simulations were in general agreement with observed data. Best agreement was obtained for the lower lakes. The model appeared to underestimate deposition to Superior lake, particularly for sulphur. Mass budgets of sulphur and nitrogen for Superior lake indicated that atmospheric deposition was an important part of total loading, particularly for nitrogen. Problems in separating possible emission-related trends in deposition from meteorologically-induced variability and modelling uncertainties are discussed.

The thorium isotopes were not uniformly distributed in the colloidal fractions nor in chemical equilibrium; fractions highest in thorium were also highest in DOC but had the lowest iron concentrations. The least thorium occurred in the highest size ranges. The likeliest explanation lay in the chemical properties of radium-228 and uranium-238, the precursors of thorium-228 and thorium-230 respectively. Radium-228 preferentially reacted with the smaller fulvic and humic acid molecules while uranium-238 was more widely spread over the 3 smallest fractions. For these reasons, care was necessary when determining thorium isotopic ratios to check uniformity of distribution in the samples.

AN - 13709663; S199343095 AB - In planning a study on opportunities for waste reduction and energy savings in the chemical industry, several industries in the U.S.A. were consulted and these are listed. Possible ways of reducing waste, that could be applied either singly or in combination, are outlined. Data are presented on the maximal theoretical energy difference potential (the difference between minimal energy theoretically required and actual energy consumed or recovered) in the manufacture of over 30 important chemicals. A schematic diagram of the principal flows and transformation of material in the petrochemical industry is included. The possible implementation of waste minimization alternatives in the chemical industry in the short-term (0-5 years), medium-term (5-10 years) and long-term (over 10 years) is tabulated; some of these alternatives are described briefly.

However, due to the passage of several recent regulations, most notably the Clean Air Act in the United States in 1990, there is an emerging perception that the problem in these western nations is nearing solution. The situation in the developing world, particularly in Asia, is much bleaker. Given the policies of many Asian nations to achieve levels of development comparable with the industrialized world - which necessitate a significant expansion of energy consumption (most derived from indigenous coal reserves) - the potential for the formation of, and damage from, acid deposition in these developing countries is very high. This article delineates and assesses the emissions patterns, meteorology, physical geology, and biological and cultural resources present in various Asian nations. Based on this analysis and the risk factors to acidification, that several areas in Asia are currently vulnerable to acid rain. These regions include Japan, North and South Korea, southern China, and the mountainous portions of southeast Asia and southwestern India. Furthermore, with accelerated development (and its attendant increase in energy use and production of emissions of acid deposition precursors) in many nations of Asia, it is likely that other regions will also be affected by acidification in the near future. Based on the results of this overview, it is clear that acid deposition has significant potential to impact the Asian region. However, empirical evidence is urgently needed to confirm this and to provide early warning of increases in the magnitude and spread of acid deposition and its effects throughout this part of the world.

Previously we demonstrated that for full ML expression, a four-stage preclinical sequence is required, namely (I) suppression, (II) recovery, (III) accommodation, and (IV) preleukemic transition. Within this pathological sequence, a critical early event has been identified as the acquisition of radioresistance by hematopoietic progenitors that serves to mediate a newfound regenerative hematopoietic capacity. As such, this event "sets the stage" for preleukemic progression by initiating progression from preclinical phase I to II. Due to the nature of target cell suppression, the induction of crisis, and the outgrowth of progenitors with altered phenotypes, this preleukemic event resembles the "immortalization" step of the in vitro transformation sequence following induction with either physical and chemical carcinogens. The radiological, temporal, and biological dictages governing this event have been extensively evaluated and will be discussed in light of their role in the induction and progression of chronic radiation leukemia.

AN - 72494924; 1955323 AB - The relationships of Rn levels in basements and first floors of homes to topographic location in a northeastern ridge and valley section of Pennsylvania were investigated. Topographic variables relating to elevation and slope were quantified and related to house Rn levels using both conventional and classification and regression tree (CART) analyses. The original interest was in using topographic correlates to estimate missing values in epidemiologic studies. In this area, Rn levels are usefully predicted by relative and absolute elevations and nearness to hills and ridges. Three- to fourfold differences in geometric mean Rn levels can be obtained for categories representing significant portions of the population of houses. The relationship of first-floor to basement Rn levels was found to be curvilinear and modestly affected by topography.

AN - 72490816; 1955331 AB - A method has been developed for the rapid isolation and quantitation of 89Sr and 90Sr in urine samples. The radiostrontium is concentrated from the bulk urine sample by coprecipitation with calcium phosphate. The precipitate is then wet ashed with nitric acid, and a solution of the resulting residue in 2 M HNO3-0.5 M Al(NO3)3 is passed through an extraction chromatographic column containing a supported crown ether that preferentially retains strontium. Sorbed strontium may then be eluted from the column with either dilute HNO3 or water and counted via liquid scintillation. A new counting scheme that permits quantitation of both 89Sr and 90Sr on the same day the separation is performed is described.

AN - 72452000; 1682401 AB - The dose-response for the induction of initial double-strand breaks (dsb) in DNA of human epithelioid cells by JANUS 0.85 MeV fission-spectrum neutrons was parabolic as assayed by a calibrated neutral filter elution technique. The relative biological effectiveness (RBE) of these neutrons relative to 60Co gamma-rays was unity. The kinetics of repair after a 60 Gy gamma-ray exposure were biphasic. About 65% of these dsb were rapidly repaired (T 1/2 of approximately 2 min), and the remainder were almost completely removed after 150 min at a slower rate (T 1/2 = 30 min). After the same dose of JANUS neutrons, the rapid repair component was markedly reduced (possibly not a significant repair component), and the bulk of the dsb were sealed more slowly (T 1/2 = 90 min). After 150 min, 25% remained unsealed. Even after a lower neutron dose (20 Gy), a proportion of the dsb were refractory to repair. Thus, unrepaired (or irreparable) dsb induced by high energy neutrons might explain the high RBE of neutrons for cell killing.

I. Effect of total dose and dose rate. AN - 72463197; 1947009 AB - The effects of protracted exposure to 60Co gamma rays on survival and tumor induction in the beagle were investigated. Total accumulated doses of 450, 1050, 1500, and 3000 cGy were given at rates of 3.8, 7.5, 12.8, and 26.3 cGy/day. Hazard models were used to identify trends in mortality associated with radiation exposure. The probability of an acute death (related to hematopoietic aplasia) was positively associated with the total dose received and the rate at which the dose was delivered. Once an animal survived the initial hematopoietic effects of radiation exposure, the risk of death from causes other than cancer, while elevated, was far less responsive than the neoplastic end points. No relationship between tumor or chronic nontumor deaths and dose rate could be identified. However, survival curves for tumor mortality did separate into a pattern clearly dependent on the accumulated dose.

AN - 72153781; 1924738 AB - The mutagenic and carcinogenic properties of fission-spectrum neutrons (KERMA-weighted mean energy of 0.85 MeV) from Argonne National Laboratory's JANUS reactor are substantially greater than those of low-LET radiation sources such as X-ray and 60Co photons. However, in contrast to the vast amount of work focused on chemical protection against damage induced by low-LET radiation, studies on the prevention of carcinogenic damage induced by fission neutrons have been limited. We have investigated the protective properties of the thiophosphorate compound S-3-(3-methylaminopropylamino)propylphosphorothioic acid (WR-151327) against carcinogenesis and life shortening in the B6CF1 hybrid mouse strain. Male and female mice, 200 of each sex per experimental group, were irradiated individually at 110 days of age. WR-151327 was administered intraperitoneally at a dose of 580 mg/kg 30 min prior to irradiation with a dose of 10 cGy. Animals were housed five to a cage; cage locations in holding rooms were controlled by computer and randomized. Mice were checked daily and all deceased animals were necropsied. A neutron dose of 10 cGy significantly altered the patterns of death of male and female animals compared to corresponding unirradiated control groups (logrank P values of 0.01 and 0.07, respectively). This was evidenced by a shortening of the life span due to tumor induction in the irradiated groups. WR-151327, when administered 30 min prior to irradiation, effectively protected both male and female animals from these effects. The life curves of irradiated male and female animals and those of corresponding unirradiated control groups were not significantly different (logrank P values of 0.63 and 0.25, respectively).

AN - 72152986; 1924754 AB - Protracted courses of low-daily-dose gamma irradiation elicit high incidences of myeloproliferative disease, principally myeloid leukemia (ML), in beagle dogs. A four-phase preclinical sequence in the induction of ML has been described: (1) suppression, (2) recovery, (3) accommodation, and (4) preleukemic transition. Within this sequence, a critical "early"-occurring hematopoietic target cell event that promotes progression of preclinical phases I and II has been identified and characterized by an acquisition of increased radioresistance to low-LET gamma rays by granulocyte/monocyte lineage-committed progenitor cells (CFU-GM). To gain further insight into the basis of this critical event, the acquired survival response of preleukemic progenitor cells has been probed in vitro with high-LET fission neutrons. For these studies, marrow CFU-GM were isolated from chronically irradiated preleukemic dogs, as well as from nonirradiated controls, subjected to graded doses (0-300 cGy) of either JANUS fission neutrons or 60Co gamma rays, and assayed for survival by a standard cloning assay. Major observations resulting from these assays include the following. First, the acquired radioresistance of preleukemic CFU-GM to low-LET gamma rays noted previously extends to high-LET fission neutrons as well. Relative to control CFU-GM exhibited small but significant increases in radioresistance of about 10 cGy with an average D0 value of 38 (+/- 2.3) cGy for preleukemic CFU-GM, and 28 (+/- 1.3) cGy for the control levels, the CFU-GM irradiated within a marrow dose range of 10-75 cGy. Second, at higher neutron doses (150-600 cGy), fractional survival of both control and preleukemic CFU-GM declined nonexponentially, suggesting the existence of a small, radioresistant subpopulation constituting about 2% of the total marrow CFU-GM within normal nonirradiated dogs, and a 15% fraction of the progenitor cell population in preleukemic marrow (preclinical phases II-IV). The latter is most likely the result of a normally minor subpopulation gaining a growth advantage due to its inherent radioresistance and clonally expanding in the strong selective pressure of chronic marrow irradiation in vivo.

AN - 72151776; 1924741 AB - The impact of the biological end point selected as a synoptic measurement of mortality for the detection of protraction effects and the estimation of RBE values was investigated. Life shortening was chosen as an end point because it summarizes, in a single index, the cumulative effect of all injuries experienced by an organism. Cumulative mortality at a single time point and the hazard function (age-specific failure rate) were chosen to incorporate progressively more information, respectively, about the distribution of mortality through time. Data for both sexes of the B6CF1 mouse exposed to fission neutrons from the JANUS biomedical research reactor and 60Co gamma rays were analyzed. Three basic patterns of exposure were compared: single exposures, 24 equal once-weekly exposures, and 60 equal once-weekly exposures. The interpretation of results was influenced by the biological end point used as the synoptic measurement. An augmented response with protraction of the neutron exposure depended on the accumulated dose using the life-shortening response while this effect was nonexistent when cumulative mortality or the hazard function was used. A reduced effectiveness of protracted gamma-ray exposures was apparent for all end points. The hazard function analyses suggest that the time domain must be considered in the detection of protraction effects for either radiation quality and the subsequent estimation of RBE values.

In the neptunite structure, Ti and (Fe,Mn,Mg) octahedra share edges to form chains that run along [110] and [ (super -) 110]. These chains are, in turn, linked through shared corners along [001]. The resulting octahedral framework is interwoven by a similar [Si (sub 8) O (sub 22) ] tetrahedral framework. Li, Na and K occupy 6-, 8- and 10- coordinated sites within the framework. The metal-containing polyhedra show strong distortions at all T. In particular Ti exhibits a strong off-centre displacement (approx 0.25 Angstrom) within its octahedron, leading to four Ti-O distances of 2.0 Angstrom, one of 2.2 Angstrom and one of 1.7 Angstrom . The displaced Ti position is in good agreement with a position that minimizes differences between ionic bond strengths and is interpreted as an energy minimum in an ionic potential model. Mossbauer spectra collected at 77 K, 293 K and 400 K indicate all Fe to be present as octahedral Fe (super 2+) . Although two distinct Fe positions were found in the structure, 77 K and 293 K spectra display only one quadrupole doublet. Only two Fe sites can be resolved in the 400 K spectrum. It is suggested that the T dependence of octahedral edge distortions is responsible for the separation of the Mossbauer doublets.

AN - 72097849; 1909939 AB - Mutation induction after exposures to 250 kVp X-rays, alpha-particles from the radon daughter 212Bi, and fission-spectrum neutrons from the JANUS reactor was studied in Chinese hamster ovary (CHO) K1 cells and in CHO-10T5, a K1 derivative containing the bacterial gene xanthine-guanine phosphoribosyl transferase (gpt). Mutation induction was analyzed at three genetic loci: the gpt locus, the hypoxanthine-guanine phosphoribosyl transferase (hprt) locus, and the thymidine kinase (tk) locus. After X-irradiation, mutants were induced at the tk loci at approximately 8-9 times the rate of mutant induction at the hprt locus, and the rate of mutant induction at the gpt locus was 8-10 times greater than that at the hprt locus. Neutron and alpha-radiation were more effective mutagenic agents. Mutant frequencies were approximately 4- to 6-fold higher than for X-rays at the hprt and gpt loci and greater than 12-fold greater than X-rays at the tk locus. The greater sensitivity of the tk locus to mutation induction by ionizing radiation (especially neutron and alpha-particle radiation) compared to the hprt locus is likely to be due to the recovery of an additional class of mutants, possibly ones containing larger-sized mutational events. Approximately half of the X-ray-induced tk-1- mutants were small-colony mutants, and 75% of the alpha- and neutron-induced tk-1- mutants were small-colony mutants. The increase in the proportion of small-colony mutants seen with increasing radiation linear energy transfer (LET) suggests that the radiation quality influenced the type of mutation recovered at this locus. There is probably a different reason for the hypersensitivity of the gpt locus because the frequency of gpt mutants, compared to the hprt locus, was independent of radiation quality. Therefore, the LET dependence of mutant induction is gene specific and not necessarily related to the size of deletion recoverable.

AN - 80731279; 1651155 AB - We have demonstrated that S-2-(3-aminopropylamino)ethylphosphorothioic acid (WR2721) administered to mice 30 min prior to a relatively low dose of ionizing radiation is effective in protecting against radiation-induced carcinogenesis and subsequent life shortening. Female C57BL/6JANL x BALB/cJANL F1 mice, 200 per group, were exposed to gamma radiation at a dose of 206 cGy. Additional groups of 200 animals were sham treated, given injections of 400 mg/kg of WR2721, or administered WR2721 and the irradiated with 60Co photons at doses of 206 cGy or 417 cGy. Mice were treated at 110 days of age. They were housed five to a cage and were checked daily throughout life. All deceased animals were necropsied, and tissues were removed and fixed for histopathological analysis. Over 90% of the animal deaths were due to tumor involvement. WR2721 afforded significant protection (P = 0.0016) against radiation-induced malignancies (i.e., a total of 164 tumor codes were used) following a dose of 206 cGy. Protection against lymphoreticular tumors in particular was significant (P = 0.0165). Subsequent survival time in WR2721-protected animals (compared with matched irradiated controls) was extended by 65 days. Mice irradiated with 417 cGy following administration of WR2721 exhibited a response similar to those irradiated without the protector at a dose of 206 cGy (P = 0.26). Cumulative survival curves for unirradiated mice were unaffected by a single dose of WR2721. These data indicate a potential novel benefit for radioprotectors in cancer therapy. WR2721 and similar aminothiols may be effective adjuvants for reducing the risk of therapy-induced secondary cancers in patients who have an excellent prognosis for cure and long-term survival.

AN - 80602286; 1675236 AB - Previous work has demonstrated that radiation exposure modulates the expression of a series of genes, including those that encode cytoskeletal elements. The experiments reported here were designed to examine (1) the comparative effects of neutrons administered at high versus low dose-rates, (2) the comparative effects of neutrons on cycling versus resting cells and (3) the comparative effects of neutrons versus gamma-rays on beta- and gamma-actin mRNA accumulation in Syrian hamster embryo (SHE) cells 1 and 3 h post-irradiation. JANUS fission-spectrum neutrons from Argonne National Laboratory's JANUS reactor administered at high (12 cGy/min) dose-rates had little effect on resting cells, but at very low dose-rates (0.1 cGy/min) had a repressive effect on gamma-actin mRNA accumulation. Increased accumulation of beta-actin mRNA was detected following the exposure of cells to neutrons administered at high dose-rates, but repression of beta-actin mRNA was observed when neutrons were administered at low dose-rates. Cycling cells (unexposed and neutron irradiated) in all cases expressed higher levels of all actin-specific mRNAs than resting cells; beta-actin mRNA (but not gamma-actin mRNA) was induced to a greater extent in cycling cells than in resting cells during the first hour following neutron exposure. In resting cells, however, low dose-rate neutrons were more effective than low dose-rate gamma-rays at repressing both gamma- and beta-actin mRNA accumulation. These results demonstrate the differential effects of radiation quality (neutrons versus gamma-rays) and cell-cycle state on the modulation of actin isotype-specific gene expression.

AN - 80556394; 2030713 AB - We investigated the radiobiological effects of the radon daughter bismuth-212 (212Bi) in Chinese hamster ovary (CHO) K1 cells and in xrs-5 cells, which are X-ray sensitive and deficient in the ability to rejoin DNA double-strand breaks. The cells were exposed to 250 kVp X-rays or to 212Bi chelated to diethylene triamine pentaacetic acid (DTPA); chelation of 212Bi to DTPA prevented its attachment to or entry into the cells. Cytotoxic, clastogenic, and mutagenic responses of the cells were measured and RBEs (D10, 2 chromatid aberrations/cell and 10 induced 6-thioguanine-resistant mutants) were calculated to be 3.8, 3.5, and 3.9, respectively for K1, and 1.4, 0.8, and 5.1, respectively, for xrs-5. With the exception of the RBE of less than 1 for alpha-induced aberrations in xrs-5, the results are consistent with the following conclusions: (1) alpha-particles are in general more effective cytotoxic, clastogenic and mutagenic agents than X-rays; (2) the primary lethal and clastogenic lesion induced by both X-rays and alpha-particles is probably a DNA double-strand break; (3) DNA double-strand breaks induced by alpha-radiation are less well repaired than those induced by X-rays, although a portion of alpha-induced damage is repairable; and (4) deficiencies in rejoining DNA double-strand breaks affect the clastogenic and cytotoxic effects of X-rays and alpha-radiation, not their mutagenic effects. The RBE of 0.8 for aberration induction in xrs-5 cells could reflect a deficiency in the ability of these cells to convert alpha-induced damage to chromosome aberrations. Alternatively, the RBE of less than 1 might reflect an unusual sensitivity of xrs-5 cells to alpha-induced G2 delays.

Two primary mechanisms describing why declining mortality can lead to worsening health are identified: (1) medical technology can improve the survival of those with disabling conditions, & (2) declining mortality from fatal diseases leads to a shift in the distribution of causes of disability from fatal to nonfatal diseases of aging. Procedures for testing this hypothesis are discussed. 3 Figures, 56 References. Adapted from the source document.

AN - 80448826; 1995513 AB - Effective dose-equivalent responses have been calculated for external exposure from residual photon emitters in soil. The calculations are based on the assumption that the receptor is located 1 m above the contaminated ground. A Monte Carlo algorithm was developed to perform the photon transport calculation for the soil/air configuration, in which the soil constituents were assumed to be similar to those of the earth's crust. Photon cross-sections for soil were based on the latest cross-sectional information generated by the U.S. National Institute of Standards and Technology. For every incident photon at the receptor, an estimate of the air-absorbed dose was calculated first and then converted into the effective dose equivalent. The effective dose equivalent is based on the concept of weighted organ doses, as recommended by the ICRP. The ICRP's latest conversion coefficients were used to transform point air-absorbed doses into effective dose equivalents. Baseline effective dose responses were obtained for monoenergetic photon sources assumed to be distributed uniformly in soil for energies ranging from 0.01 to 10 MeV, soil thicknesses from 0 to 5 mean-free-path (mfp) lengths, and soil densities from 1 to 2 g cm-3. On the basis of the calculated dose responses, empirical relationships were obtained for correlating the dose responses with the soil depths and densities for each source energy. The derived correlations contain a convenient exponential form that describes the depth-dose relationship for an estimated accuracy within about 15%; soil densities show an inverse relationship with dose responses. Results of the effective dose-equivalent response can be used to calculate effective dose-equivalent responses for gamma-emitting radionuclides that are commonly identified as residual radioactive materials in soil.

AN - 80441258; 1993848 AB - mAb raised against synthetic peptides derived from cholera toxin, myohemerythrin, and sickle hemoglobin were analyzed by both solid-phase and solution-phase methods. Antipeptide mAb against cholera toxin (mAb TE32 and TE33), against myohemerythrin (mAb B13I2, B13C2, and B13F2), and against sickle hemoglobin (mAb HuS-1 and HuS-2), had been previously described and used for vaccine development, structural characterization, or identification of a specific antigenic determinant, and each was apparently capable of binding both peptide and native Ag. In this study, all were found to bind whole protein when tested against immobilized Ag in a standard solid-phase assay (ELISA), yet none of the antibodies recognized the Ag in its true native form, failing to bind when tested in several solution-phase assay systems, including size exclusion HPLC. This discrepancy may be the result of modifications of the epitope created by interaction and possible denaturation of the protein on the solid-phase matrix. As a consequence, binding of these antibodies to peptides, either immobilized or in solution, or to immobilized protein, cannot be used to infer that the peptide has assumed a conformation that corresponds to that of the cognate sequence in the native protein. A re-evaluation of binding data that relates antipeptide mAb to native structural characteristics may be necessary.

Subsidence due to compaction and loss of pore water is believed to be one of the primary land loss factors, whereas subsidence due to gas emission is generally believed to play a significant role only in the upper one or two meters of a wetland. Evidence to the contrary is presented here that suggests that degasification subsidence is a more important mechanism contributing to land loss than previously thought. In addition, potential degasification subsidence can be quantified if the depression from normal compressional and shear wave velocities is known. Velocity reductions of 30 to 75% from compressional wave velocity in water and extending to depths of tens of meters have been observed in a saltwater marsh in Louisiana. An order of magnitude reduction in velocity has been observed previously in gas-rich sediments on the adjacent continental shelf, where biogenic gas is observed to depths of 1 km or more. The ratio of normal to depressed compressional wave velocities is used to calculate potential degasification subsidence.

AN - 80501092; 2011627 AB - Cell survival parameters and the induction and repair of DNA single-strand breaks were measured in two Chinese hamster ovary cell lines after irradiation with monochromatic UVA radiation of wavelength 365 nm. The radiosensitive mutant cell line EM9 is known to repair ionizing-radiation-induced single-strand breaks (SSB) more slowly than the parent line AA8. EM9 was determined to be 1.7-fold more sensitive to killing by 365-nm radiation than AA8 at the 10% survival level, and EM9 had a smaller shoulder region on the survival curve (alpha = 1.76) than AA8 (alpha = 0.62). No significant differences were found between the cell lines in the initial yields of SSB induced either by gamma-radiation (as determined by alkaline sucrose gradient sedimentation) or by 365-nm UVA (as determined by alkaline elution). For measurement of initial SSB, cells were irradiated at 0.5 degrees C to minimize DNA repair processes. Rejoining of 365-nm induced SSB was measured by irradiating cells at 0.5 degrees C, allowing them to repair at 37 degrees C in full culture medium, and then quantitating the remaining SSB by alkaline elution. The repair of these breaks followed biphasic kinetics in both cell lines. EM9 repaired the breaks more slowly (t1/2 values of 1.3 and 61.3 min) than did AA8 (t1/2 values of 0.9 and 53.3 min), and EM9 also left more breaks unrepaired 90 min after irradiation (24% vs 8% for AA8). Thus, the sensitivity of EM9 to 365-nm radiation correlated with its deficiency in repairing DNA lesions revealed as SSB in alkaline elution.(ABSTRACT TRUNCATED AT 250 WORDS) JF - Photochemistry and photobiology AU - Churchill, M E AU - Peak, J G AU - Peak, M J AD - Molecular Photobiology Group, Argonne National Laboratory, IL 60439-4833.

AN - 80430538; 1989938 AB - One of two boys born in September 1949 who played on U mill tailings between age 8 and 12 was diagnosed as having leukemia at age 15.5. The exposed and control subjects were well matched; they were approximately the same age and both were 1.85 m (6' 1") in height and weighed 75.2 kg (165 pounds). The result obtained by gamma spectrometric method for the exposed subject was 0 +/- 17 Bq (0 +/- 470 pCi), while that for the control subject was 4 +/- 15 Bq (100 +/- 400 pCi). The result obtained by the Rn breath method for the exposed subject was 4.4 +/- 0.7 Bq (120 +/- 20 pCi), while that for the control was 5.4 +/- 1.4 Bq (150 +/- 38 pCi). These results suggest that the 226Ra body burden of the exposed subject is within the range of those observed in subjects exposed only through normal food sources, which have a mean 226Ra content of 1.5 Bq (range: 0.4-4.4 Bq) so that no significant mill-tailing intake is indicated. The best estimate of alpha particle dose to the red marrow from 226Ra and its decay products was 0.05 mGy at age 14 and 0.10 mGy at age 38. This dose, when compared to that observed in the dial painters, suggests that the leukemia was not caused by uptake of Ra from the mill tailings.

AN - 80523916; 1850394 AB - 80mBr (half-life = 4.43 h) is an Auger electron emitting nuclide with convenient properties for investigating Auger electron cytotoxicity and with potential for labeling in vivo radiotherapeutic agents. We have investigated three cyclotron target systems capable of generating 80mBr of sufficiently high specific radioactivity (no carrier added) for biomedical experiments. A 83Kr gas target irradiated with 21.5 MeV deuterons made 80mBr at a production yield of 1.6 +/- 0.2 mCi/muAh at saturation. A five-fold increase in 80mBr yield was obtained from 15 MeV proton irradiation of thin elemental Se enriched in 80Se targets although technical improvements are expected to further raise this production yield. This route is therefore superior for current medical cyclotrons. Irradiation of a reusable 80Se copper selenide target also yielded multi-millicurie amounts of 80mBr, and recovery of radiobromine by dry distillation is faster and more convenient than in the elemental Se target, but an optimum copper selenide target for 80mBr production has not yet been built.

Whole-body Counting Working Group. AN - 80483294; 1900815 AB - This report discusses the principles, techniques, and application of whole-body counting with respect to previous radiation exposure. Whole-body counting facilities are located nationwide and have a wide range of capabilities. A listing of these facilities is provided in Appendix A. However, only a few facilities are truly state-of-the-art and have the sophisticated capabilities required to attempt detection of low-level activity in vivo. Measurements made many years after exposure can be extremely difficult to interpret. The precision and accuracy of resulting dose estimates are functions of such factors as the assumptions made concerning intake, time since intake, radionuclide metabolism, and level of intake. The indiscriminate application of metabolic models to current body contents or minimum detectable amounts of radionuclides with relatively short effective half-lives (such as 137Cs) can lead to absurd results when used as a basis for calculating intakes 25 and 40 y ago. Skull counting for 90Sr-90Y and 239,240Pu can set upper limits on possible uptakes and radiation doses, but in the case of 239,240Pu, the limits are rather high. In both cases, the accuracy of the limits depends on the metabolic models used in the calculations. These models (ICRP 1979) were developed to set safety standards for the intakes of radionuclides by workers and are not intended to be used to back-calculate uptakes and radiation doses from measurements made long after the uptake. There are, therefore, large uncertainties in any conclusions derived from these calculations. The experience gained over the years with whole- and partial-body counting has consistently shown that they are of little use in determining body contents of radionuclides resulting from exposure to weapons debris decades earlier. The development of new detectors such as an array of lithium-drifted silicon devices offers some hope of lowering the minimum detectable amount (MDA) for Pu and Am, but such detectors are still several years from routine application and do not represent current state-of-the-art. Furthermore, it is doubtful that such improvements will be sufficient to meet the need of assessing radiation exposures that occurred decades earlier.

AN - 80365270; 1986263 AB - The initial yields of DNA-to-protein crosslinks (dpc) caused by ionizing and nonionizing radiations were compared, with emphasis upon values within the biological dose ranges (D0). Induction of dpc in cold (0-0.5 degrees C) human P3 teratocarcinoma cells was measured by using alkaline elution techniques after exposure to monochromatic UVC (254 nm), UVB (313 nm), UVA (365 and 405 nm), and blue light (434 nm). UVC and UVB light induced detectable numbers (about 100 dpc per cell per D0). Monochromatic UVA radiations produced yields about 8 times higher than UVC or UVB (for 365 nm, about 1500 dpc per cell per D0) Similar results at low doses were obtained for measurements of single-strand breaks induced by the different radiations. The action spectra for dpc were closely similar. The biological significance of these relatively high numbers of DNA lesions caused by environmental nonionizing radiation that readily penetrates into human skin is not understood.

AN - 72643411; 1782207 AB - Chemical, physical, or mechanical insults to a cellular system cause changes in the rates of protein synthesis or degradation. To define patterns of quantitative protein changes and identify the biochemical basis of those changes, we are studying fluctuations in mouse liver protein abundance in response to factors such as stages of maturation, changes in diet, and exposure to chemicals. Two-dimensional gel electrophoresis (2DE) together with computer-assisted data analysis is used to collect quantitative data from groups of 2DE patterns. Our analysis of liver protein expression in mice treated with four different chemicals known to cause peroxisome proliferation serves as an example of the changes in protein expression that can be monitored by using this approach. The database we are building indicates that changes specific to a particular treatment as well as generalized effects can be identified, providing the opportunity to identify patterns of protein expression that are indicators of biological response to different types of cellular insults.

A modified procedure was designed to test for completeness of reaction at a low combustion T (225 degrees C). The carbon fractions released at 225 and 500 degrees C, respectively, were isotopically relatable to the chemical alteration of the organic material which occurred during the analytical process, not to different components in the original materials.

An example is included of the application of this procedure to a lake with 3 tributaries, assuming that several monitoring strategies with known costs and values could be applied to each tributary. This approach could be used to define either a fixed-cost monitoring programme that would result in a minimal load estimate uncertainty or the lowest-cost programme that would achieve a stated level of uncertainty.

The system was suitable for unattended operation in field conditions at moderate pumping rates and under controlled atmospheres to minimize sampling artefacts. The results of field sampling were compared with those of laboratory analyses using single-cartridge hollow-fibre ultrafilters. A good degree of agreement was found. The apparent sample reproducibility was 15 per cent. The evaluation confirmed that field collection of colloidal materials with minimal sample perturbation was feasible using the system.

The overall effects of thermal interaction between magmatic intrusions and carbonaceous sediments in fossil systems were complex and not necessarily predictable in practice. Isotopic data for organic carbon indicated that for the system the thermal shock caused by the intrusion caused migration of labile organic carbon similar to the residual kerogen. Decarbonation apparently also occurred within the thermal aureole of the intrusion.

On completion of the first phase, in the course of which the groundwater re-enters the aquifer, the soil is tilled and exposed to the atmosphere and aided by solar radiation and biodegradation, the contaminants are volatilized or mineralized, and the soil then becomes available for a further treatment cycle. As a basis for the operation of such a system, isotherms were constructed for various clays in a model system, using benzene and toluene as typical contaminants. The effects of temperature and drying time on the subsequent liberation of the adsorbed chemicals were also investigated, together with the possible deterioration in the adsorptive capacity after several cycles.

AN - 80220715; 2274962 AB - Evidence is accumulating that the levels of covalent carcinogen-macromolecule adducts, including adducts with hemoglobin, reflect biologically effective levels of carcinogen exposure. The purposes of the present study were (a) to establish a cellular system for obtaining adducts between intracellular human hemoglobin and metabolites of polycyclic aromatic hydrocarbons (PAH), and (b) to evaluate techniques for chromatographic characterization of the adducts. We showed that hemoglobin-benzo[a]pyrene adducts were formed when human erythrocytes were treated with [3H]benzo[a]pyrene (BP) in the presence of hamster embryo fibroblasts, which are known to be effective for BP metabolism. After lysis of the erythrocytes, noncovalently bound BP and its metabolites were effectively removed from hemoglobin under mild conditions by using hydrophobic interaction and size-exclusion liquid chromatography. Three to five distinct adducts were resolved by reversed-phase and ion-exchange liquid chromatography. As determined by a two-step, reversed-phase liquid chromatographic procedure, trypsin treatment of globin from the cellular system yielded at least three of the four 7,8,9,10-tetrahydro-7,8,9,10-tetrahydroxy BP tetrols known to arise from mammalian metabolism of BP. This observation is consistent with both (a) the recently described formation of labile carboxyl esters via reaction of BP-7,8-dihydrodiol-9,10-epoxide (BPDE) with hemoglobin and (b) the known formation of both anti- and syn-BPDE in hamster embryo fibroblasts. In addition, high-performance liquid chromatographic analysis demonstrated the presence of other products presumed to be BP-peptide adducts because of their susceptibility to thermolysin treatment.

AN - 80105602; 2236499 AB - The systemic effects of the radiation protective agent, S-3-(3-methylaminopropylamino) propylphosphorothioic acid (WR-151327), were studied in unirradiated B6CF1 male mice. Fifty mice were injected intraperitoneally with 540 mg/kg WR-151327, and groups of five mice were sacrificed at 14-day intervals up to and including 140 days post-treatment. Ten mice served as sham-injected controls. A necropsy was performed and gross morphological abnormalities were noted. Tissues (brain, eyes, harderian gland, salivary glands, sternal bone marrow, thyroid, lung, thymus, esophagus, trachea, skeletal muscle, heart, liver, kidney, adrenal gland, spleen, small intestine, pancreas, and testes) were fixed in 10% formalin, embedded in paraffin, and sectioned. Slides were routinely stained with hematoxylin and eosin while Alizarin red stain was used to test specifically for the presence of calcium salts. Histopathological effects of WR-151327 were restricted to the testes, salivary gland, and pancreas. The caudal pole of the testes was observed to undergo progressive changes from coagulation necrosis to dystrophic calcification. The cells of the submandibular salivary gland showed mainly hyperchromatic nuclei while the pancreas showed enlarged islets of Langerhans.

AN - 79984672; 2395020 AB - Alpha emitter-labeled antibodies (Abs) are of considerable interest in cancer therapy. Alpha particles are densely ionizing and therefore have a high radiobiologic effectiveness, and the cell killing produced is influenced very little by dose rate or hypoxic conditions. LS174T human colon adenocarcinoma spheroids were used in this study to evaluate the efficacy of alpha emitter-labeled Abs in a three-dimensional model. NRLU-10, an IgG2b Ab to a pancarcinoma antigen, and its Fab fragment were used. Initial kinetic studies using 125I-NRLU-10 revealed that a large number of binding sites/cell and high Ab affinity led to slow Ab penetration. This effect could be overcome by increasing the Ab concentration ten-fold for Fab but not for intact Ab. Bismuth-212-NRLU-10 therapy was very effective in killing single cells (over 3 log reduction in surviving fraction) but was ineffective in spheroids (less than 1 log reduction). This was likely due to inadequate penetration into the spheroids before the 212Bi decayed. The use of higher Ab concentrations, tumors with fewer antigenic sites/cell for the Ab being used, lower affinity Abs, alpha emitters with longer half-lives, and pretargeting with bifunctional Ab are all potential ways of increasing the efficacy of alpha emitter-labeled Abs for cancer therapy.

Two wastewaters, one synthetic and one industrial, were used in these performance assessments. The synthetic wastewater used Jayfloc-806 as the chemical collector, and the industrial wastewater used Jayfloc-824 as the collector. The synthetic wastewater was capable of removal efficiencies exceeding 96%. The DAF system provided the best metal removal (Zn, Cu, Pb, and Ni), and the NAF system, the poorest metal removal. For the industrial wastewater, removal efficiencies were lower, on the order of 75%. For lower collector dosages, use of the DAF system resulted in the lowest residual concentrations, whereas at higher dosages (about 5 mg/L), use of the IAF system resulted in the lowest concentrations. Enhancement ratios were much greater for the industrial wastewater (compared with the synthetic wastewater).

AN - 80052891; 2217550 AB - Neutral filter elution at pH 7.2 and 9.6 was used to measure the induction of DNA lesions in human P3 teratocarcinoma cells by monochromatic 254-, 270-, 313-, 334-, 365-, and 405-nm radiation and by 60 gamma rays. In this assay DNA double-strand breaks (dsb) increase the rate of elution of DNA from cell lysates on a filter. Yields of dsb as measured by this procedure were determined by using a calibration of the assay that correlates elution parameters with number of dsb caused by disintegration of 125I incorporated into the DNA. Analysis of fluence responses obtained by using the calibrated assay indicated that the number of dsb induced per dalton of DNA as measured by this assay is proportional to the square of the fluence at all the energies of radiation studied, implying that the induction of these lesions may be a two-hit event. Analysis of the relative efficiencies for the induction of dsb by ultraviolet radiation, corrected for quantum efficiency, revealed a spectrum that coincided closely with that for the induction of single-strand breaks (ssb) in the same cells, having a close fit with the spectrum of nucleic acid in the UVC and UVB region below 313 nm, and a shoulder in the UVA region. It was calculated, however, that there may be too few ssb for dsb to result from randomly distributed closely opposed ssb.

AN - 79833821; 2354444 AB - Members of the protein kinase C (PKC) gene family have been shown to play an important role in tumor promotion and regulation of cell growth. Experiments were designed to examine the effects of different qualities of ionizing radiation administered at a variety of doses and dose rates on the expression of PKC-specific mRNA in confluent Syrian hamster embryo cells. The results of these experiments showed that low-linear energy of transfer (LET) radiations (such as X-rays and gamma-rays) can induce increased expression of PKC mRNA within 1 h after radiation exposure. Levels of expression of PKC mRNA were increased 4- to 6-fold over unirradiated controls. Dose effects were evident, with increased accumulation of PKC mRNA at higher doses (ranging from 6 to 200 cGy). Induction of PKC mRNA occurred at a time when total cellular transcription was reduced following irradiation. Similar exposure of the cells to fission spectrum JANUS neutrons, however, had little effect on PKC mRNA expression. Modest induction (2-fold compared to untreated cells) occurred when irradiations were at very low dose rates (0.5 cGy/min). These results suggest that induction of PKC mRNA may be a step in the transformation process caused by ionizing radiation. In addition, they demonstrate that different qualities of radiation may regulate PKC differently.

AN - 80229745; 1980599 AB - To study the induction of differentiation in human melanoma cells, we treated 12 melanoma cell lines with mycophenolic acid and tiazofurin, inhibitors of IMP dehydrogenase (IMPDH). In all cell lines studied, both agents inhibited cell growth and increased melanin content. However, the degree of growth inhibition did not necessarily correspond to the increase in melanin content. A detailed analysis of the HO and SK-MEL-131 cell lines indicated that mycophenolic acid and tiazofurin caused a time- and dose-dependent increase in the expression of a series of other maturation markers, including formation of dendrite-like structures, tyrosinase activity, and reactivity with the CF21 monoclonal antibody. The growth inhibition and melanogenesis induced by the IMPDH inhibitors was abrogated by the addition of exogenous guanosine. No such effect was observed after treatment of the cells with phorbol 12-myristate 13-acetate or retinoic acid, two other inducers of differentiation in these cells. The mycophenolic acid- and tiazofurin-treated cells also showed an increased level of IMPDH mRNA and protein, perhaps because of compensation for the inhibitor-mediated decrease in IMPDH activity. In contrast, treatment with phorbol 12-myristate 13-acetate or retinoic acid resulted in decreased levels of IMPDH mRNA and protein. The lack of a consistent pattern of IMPDH expression in the cells treated with IMPDH inhibitors and phorbol 12-myristate 13-acetate or retinoic acid suggests that the altered expression of IMPDH is not a general requirement for the induction of cell differentiation in these cells. Our results also suggest that IMPDH inhibitors may provide a useful approach to circumvent the differentiation block in melanoma.

AN - 79597809; 1967583 AB - The IMP dehydrogenase inhibitors mycophenolic acid (MPA) and tiazofurin (TZ) induce a time- and dose-dependent inhibition of cell growth, as well as differentiation in T-lymphoid CEM-2 leukemia cells. The differentiated cells have acquired a suppressor/cytotoxic T-lymphocyte phenotype characterized by reactivity with maturation-specific monoclonal antibodies. Coadministration of guanosine and hypoxanthine reduces the growth inhibition and diminishes the induction of differentiation by either MPA or TZ. No such reduction was observed for differentiation induced by phorbol 12-myristate 13-acetate (PMA), another inducer of a suppressor/cytotoxic phenotype in CEM-2 cells. During the first 2 days of treatment with MPA or TZ, a pattern of stable IMPDH mRNA levels and increased amounts of cellular enzyme was observed, perhaps, because of compensation for the inhibitor-mediated decrease in cellular IMPDH activity or a MPA- or TZ-mediated decrease in proteolysis of IMPDH. PMA treatment decreased the levels of IMPDH mRNA, protein, and activity. In addition, treatment of CEM-2 cells with either IMPDH inhibitors or PMA caused different alterations of the ribonucleotide pools. The lack of a consistent pattern of IMPDH expression in CEM-2 cells treated with IMPDH inhibitors or PMA indicates that no general association exists between the induction of cell differentiation and the expression of IMPDH. Nevertheless, our results indicating that IMPDH inhibitors can induce differentiation in CEM-2 cells suggest that this treatment may provide a useful approach to circumvent the differentiation block in some tumor cells.

AN - 79594904; 1967537 AB - Addition of mycophenolic acid to cultures of HL-60 cells results in a decreased cellular level of guanine nucleotides and the induction of cell differentiation. During the early stages of this induction, steady-state levels of cellular IMP dehydrogenase (IMPDH), messenger RNA (mRNA), and protein are increased, perhaps because of cellular compensation for the inhibition of IMPDH activity. The subsequent decrease in IMPH mRNA and protein levels after several days of treatment suggests a change in the control of IMPDH expression. In contrast to the pattern of increased IMPDH expression observed in the mycophenolic acid-treated cells, treatment of HL-60 cells with two other inducers of differentiation, namely retinoic acid and phorbol 12-myristate 13-acetate, resulted in stable or decreased levels of cellular IMPDH mRNA and protein. However, the kinetics of this expression were different. These results suggest that a number of factors influence the regulation of IMPDH expression during the induction of HL-60 cell differentiation, including the nature of the inducer. A decrease in the cellular IMPDH activity was observed for all of the inducers, suggesting that this decreased activity may be a determining factor in the acquisition of a mature phenotype in the HL-60 cells.

AN - 79774357; 2187533 AB - The effect of an external electric field on the optical absorption spectra of wild-type Rhodobacter capsulatus and two Rb. capsulatus reaction centers that have been genetically modified through site-directed mutagenesis (HisM200----LeuM200 and HisM200----PheM200) was measured at 77 K. The two genetically modified reaction centers replace histidine M200, the axial ligand to the M-side bacteriochlorophyll of the special pair, with either leucine or phenylalanine. These substitutions result in the replacement of the M-side bacteriochlorophyll with bacteriopheophytin, forming a bacteriochlorophyll-bacteriopheophytin heterodimer. The magnitude of the change in dipole moment from the ground to excited state (delta mu app) and the angle delta between the Qy transition moment and the direction of delta mu app were measured for the special pair absorption band for all three reaction centers. The values for delta mu app and delta obtained for wild-type Rb. capsulatus (delta mu app = 6.7 +/- 1.0 D, delta = 38 +/- 3 degrees) were the same within experimental error as those of Rhodobacter sphaeroides and Rhodopseudomonas viridis. The values for delta mu app and delta obtained for the red-most Stark band of both heterodimers were the same, but delta mu was substantially different from that of wild-type reaction centers (HisM200----LeuM200, delta mu app greater than or equal to 14.1 D and delta = 33 +/- 3 degrees; HisM200----PheM200, delta mu app greater than or equal to 15.7 D and delta = 31 +/- 4 degrees).(ABSTRACT TRUNCATED AT 250 WORDS) JF - Biochemistry AU - DiMagno, T J AU - Bylina, E J AU - Angerhofer, A AU - Youvan, D C AU - Norris, J R AD - Chemistry Division, Argonne National Laboratory, Illinois 60439.

AN - 80231173; 2278632 AB - We examined the modulation in expression of genes encoding three cytoskeletal elements (beta-actin, gamma-actin, and alpha-tubulin) in Syrian hamster embryo (SHE) cells following exposure to ionizing radiations. Early-passage SHE cells were irradiated in plateau phase with various low doses (12-200 cGy) of neutrons, gamma-rays, or x-rays. RNA samples were prepared from cells at different times postexposure and were analyzed for levels of specific transcripts by northern blots. The results revealed that alpha-tubulin was induced by both high-linear energy of transfer (LET) (neutrons) and low-LET (gamma-rays and x-rays) radiations with similar kinetics. The peak in alpha-tubulin mRNA accumulation occurred between 1 and 3 h postexposure; for gamma-actin mRNA, accumulation was similarly induced. For both gamma-actin and alpha-tubulin, the higher the dose during the first hour postexposure (up to 200 cGy gamma-rays), the greater the level of mRNA induction. In contrast, mRNA specific for beta-actin showed decreased accumulation during the first hour following radiation exposure, and remained low up to 3 h postexposure. These results document the differential modulation of genes specific for cytoskeletal elements following radiation exposure. In addition, they demonstrate a decrease in the ratio of beta-actin:gamma-actin mRNA within the first 3 h following gamma-ray exposure. These changes in mRNA accumulation are similar to those reported in some transformed cell lines and in cells treated with tumor promoters, which suggests a role for changes in actin- and tubulin-mRNA expression in radiation-mediated transformation.

AN - 80022699; 2209573 AB - The radiobiological effects of the radon daughter 212Bi were investigated in the Chinese hamster ovary cell line AA8 and its radiosensitive derivative EM9. EM9 cells rejoin radiation-induced DNA strand breaks more slowly than do AA8 cells. Three endpoints were examined: cell killing, G2-induced chromosome aberration frequency, and mutation induction at the hypoxanthine (guanine) phosphoribosyltransferase (HGPRT) locus. Cells were exposed to the alpha-emitter 212Bi chelated to diethylenetriaminepentaacetic acid (212Bi-DTPA). As expected, 212Bi-DTPA was more effective than X-rays in producing cytotoxicity, chromosome aberrations, and gene mutations. The relative biological effectiveness (RBE) for all three endpoints ranged from about 2 for chromosome aberrations to 4.4 for mutation induction. EM9 was more sensitive than AA8 cells to the cytotoxic and clastogenic effects of both X-rays and 212Bi-DTPA, suggesting that the repair deficiency in EM9 cells affects response to low- and high-linear energy transfer (LET) radiation for these endpoints. There was no significant difference between these two cell lines in their mutagenic response to X-rays and AA8 was slightly more sensitive to the mutagenic effects of alpha radiation. These results suggest that alterations in DNA repair ability may affect response of cells to both low- and high-LET radiation-induced cytotoxicity and clastogenicity, but they appear to have little effect on gene mutation induction.

The technique involved incubation of 25 g ground samples in triplicate or quadruplicate under controlled anaerobic conditions. For the landfill assays, unamended samples were run as controls and compared with assays with added water or water plus nutrients (no anaerobic innoculum). In assays with added water, consistently higher gas production rates were obtained over unamended controls. In assays of samples with high soil:refuse ratios (soil was calcareous glacial till), there was little benefit to the addition of an aqueous nutrient media over addition of water alone. Higher percent biodegradation after 200 days incubation was a function of lower volatile solids loading which, for the controls, was associated with samples of high water content and high soil-refuse ratios. With both water and aqueous nutrient media additions, variability in rates was decreased relative to the controls. Anaerobic sample handling did not result in faster onset of methanogenesis in assay bottles relative to samples given a controlled aeration. Results suggest that alteration of current landfill practice to permit addition of liquids would result in higher, more consistent gas production rates and faster landfill stabilization for alternative land uses.

Thus, adjustments in relative amounts of complexes were varied by changing halide concentrations, temperature and pressure. Spectral band positions, Raman scattering coefficients and relative concentrations of complexes are reported. For zinc/halide aqueous systems, temperature had a much more marked effect upon species distributions than pressure. Using these techniques, stepwise formation constants for metal/ligand interactions could be estimated for geochemically significant conditions and systems, even for strongly overlapping spectra such as zinc/chloride and zinc/bromide.

Mean precipitation weighted concentrations (PWC) were calculated for hydrogen ions, sulphate, nitrate, ammonium, sodium, chloride, magnesium and calcium from concurrant urban-suburban sample pairs stratified according to wind quadrant and precipitation type. The differences in chemical composition of rainfall between urban and suburban sites are summarized and interpreted. Overall PWCs were higher at the urban site for calcium(II), magnesium(II), ammonium, nitrate and chloride, equal at both sites for sodium and sulphate and lower at the urban site for hydrogen ions.

AN - 79586845; 2519727 AB - Qualitative and quantitative analysis of human hemoglobin-carcinogen adducts has potential as a diagnostic tool for estimation of biologically effective levels of carcinogen exposure and for attaining a better understanding of individual susceptibility to chemical carcinogenesis. The purpose of this study was to devise a strategy for preanalytical enrichment of the class of covalent human hemoglobin-carcinogen adducts formed by reaction at the hemoglobin beta 93 cysteine sulfhydryl groups. The results define a charge-shift strategy in which a mixture composed of natural hemoglobin (Hb-SH) and low levels of hemoglobin-S-xenobiotic adducts (Hb-SX) is treated with an anionic sulfhydryl reagent (R-), followed by anion-exchange liquid chromatographic separation of Hb-SR- from the unreactive Hb-SX adducts. Using 4-(iodoacetamido)-salicylic acid as the charge-shift reagent, we applied the strategy to the isolation of chromatographically similar adducts with either 4-nitrosobiphenyl or [3H]-N-ethylmaleimide. The strategy was effective for adduct concentrations less than or equal to 10 mumol/mol of hemoglobin. Application of the strategy provides an adduct-enriched fraction useful for subsequent analysis using either currently available techniques or alternate chemical or biochemical techniques that may be designed to take advantage of the enrichment procedure.

AN - 79261855; 2799832 AB - The kinetics of 109Cd distribution in tissues of male and female mice were measured at intervals of 5 min to 15 days after oral (100 micrograms Cd/kg; by gavage) or intravenous (1 micrograms Cd/kg; i.v.) administration of 109CdCl2. Unexpectedly, the ratio of 109Cd in liver to that in kidneys was greater than or equal to 10 within 1 h after administration by either route. However, after 4 h, route-dependent differences in distribution between liver and kidney became apparent. In mice receiving oral cadmium, the liver:kidney 109Cd ratio decreased with time to approximately 4 at 72 h after gavage. In contrast, in mice receiving IV cadmium, the liver:kidney 109Cd ratio remained high and relatively constant during the same time period. The time-dependent decrease in the liver:kidney 109Cd ratio after oral cadmium administration was caused by a 4-5-fold increase in cadmium content of the kidney that occurred between 30 min and 72 h after oral but not i.v. administration. During this time, there was no change in cadmium distribution in subcellular fractions of either liver or kidney. These results could be explained by the existence of 2 separate pathways for cadmium deposition after oral exposure. Early after exposure, cadmium may leave the intestine, bind to serum albumins or other high molecular weight proteins, and accumulate primarily in liver, as is also observed after IV cadmium administration. With time, cadmium may leave the intestinal mucosa bound to metallothionein and deposit primarily in the kidney. The different pathways of deposition after oral vs. i.v. exposure may in part explain why acute parenteral cadmium exposure causes liver toxicity, but chronic oral exposure causes renal toxicity.

AN - 79198766; 2772138 AB - We have used nondenaturing filter elution performed at both pH 7.2 and pH 9.6 to measure the induction of double-strand breaks (DSBs) in the DNA of Chinese hamster V79 cells by 60Co gamma-radiation doses between 10 and 120 Gy. The absolute DSB yields as measured by this assay were determined by using our recent calibration of the assay based upon disintegrations of 125I incorporated into the DNA. An analysis of the dose-response relationship for the induction of DSBs by 60Co gamma rays showed that the number of DSBs induced per dalton of DNA was proportional to the square of the applied dose throughout the dose range used. The contribution made by the dose to the first power was small at pH 9.6 and negligible at pH 7.2. These results suggest that DSB induction in cells by gamma rays may be entirely a two-hit event.

AN - 79159229; 2765369 AB - Administration of the photoactivable compound chlorpromazine (CPZ) to SKH-1 hairless mice via their drinking water (CPZ, 0.01%) significantly reduced the rates of accumulation and yields of squamous cell carcinomas induced by long-term repeated exposures of these animals to solar UV radiation. This protective effect of CPZ was partially reversed in mice given a single injection of ethyl nitrosourea at birth. In in vitro studies, the presence of CPZ (0.2 mM) in mammalian cell cultures enhanced the yield of DNA single-strand breaks induced in the cells by exposure to monochromatic UVA radiation at 334 nm. Collectively, the results suggest that CPZ may exert antineoplastic effects against UV-induced skin tumours by the induction of DNA damage.

AN - 79135911; 2756109 AB - Life shortening was investigated in both sexes of the B6CF1 (C57BL/6 x BALB/c) mouse exposed to fission neutrons and 60Co gamma rays. Three basic exposure patterns for both neutrons and gamma rays were compared: single exposures, 24 equal once-weekly exposures, and 60 equal once-weekly exposures. Ten different dose-response models were fitted to the data for animals exposed to neutrons. The response variable used for all dose-response modeling was mean after-survival. A simple linear model adequately described the response to neutrons for females and males at doses less than or equal to 80 cGy. At higher neutron dose levels a linear-quadratic equation was required to describe the life-shortening response. An effect of exposure pattern was observed prior to the detection of curvature in the dose response for neutrons and emerged as a potentially significant factor at neutron doses in the range of 40-60 cGy. Augmentation of neutron injury with dose protraction was observed in both sexes and began at doses as low as 60 cGy. The life-shortening response for all animals exposed to gamma rays (22-1918 cGy) was linear and inversely dependent upon the protraction period (1 day, 24 weeks, 60 weeks). Depending on the exposure pattern used for the gamma-ray baseline, relative biological effectiveness (RBE) values ranged from 6 to 43.

The methodology can be applied to many situations in which a policy decision about a toxic substance is required in the face of incomplete data. Numerical results are presented for three potentially adverse lead-induced effects of interest to EPA: elevated erythrocyte protoporphyrin (EP), hemoglobin (Hb) decrement, and intelligence quotient (IQ) decrement.

Amplitude calibration of the system enables the calculation of drop size parameters such as number density, water density, and surface area using methods similar to those with Doppler radar studies. The acoustic measurements are at 10 meter intervals within 200 meters of the surface and benefit from an almost complete separation of droplet velocity spectra from atmospheric vertical velocity spectra. Comparison of parameters with those reported in the literature shows good agreement. The chief difficulty with the method is atmospheric attenuation; however, excess attenuation due to scattering from droplets is found to be unimportant.

AN - 78968492; 2565761 AB - The structure of a number of human protooncogenes of persons with internal systemic exposure to radium was analyzed by restriction enzyme digestion and Southern blotting of their DNA. Two extra c-mos EcoRI restriction fragment length bands of 5.0 and 5.5 kilobases were found in tissue DNA from six of seven such individuals. The extra c-mos bands were detected in DNA from many, but not all, of the tissues of the individuals exposed to radium. Kidney DNA, however, from three of four individuals exposed to radium contained these alterations; kidney DNA from six age-matched controls did not. The 5.0- and 5.5-kilobase bands, which were of a similar intensity, varied in their intensity with respect to that of the normal 2.5-kilobase band of the c-mos gene. The DNAs that have the polymorphic bands also appear to have a more complex c-mos methylation pattern. Our results suggest that the c-mos restriction fragment length alterations found in individuals exposed to radium were induced rather than inherited, are epigenetic in origin, and most likely result from changes in the methylation of bases surrounding the single exon of the c-mos protooncogene.

AN - 78959899; 2565937 AB - We have examined the induction and repair of breaks induced in the DNA of Chinese hamster V79 and human P3 epithelial teratocarcinoma cells by JANUS fission-spectrum neutrons (mean energy 0.85 MeV) and 60Co gamma radiation in the biological dose range, using alkaline filter elution methods. Fission-spectrum neutrons induce fewer immediate single-strand breaks (ssb) per gray of absorbed dose than do gamma rays, as measured by alkaline elution methods. Previous survival measurements have indicated incomplete recovery after neutron exposures. The present data demonstrate that whereas most ssb caused by exposure to fission-spectrum neutrons can be rapidly repaired by both cell lines, a small but statistically significant fraction of the ssb induced by exposure to 6 Gy of neutrons is refractory to repair. In contrast, all measurable ssb induced by 3 Gy gamma rays are rapidly repaired.

VIII. Exposures to continuous gamma radiation. AN - 78900510; 2704786 AB - Data are presented on the mean aftersurvival of male B6CF1 mice exposed for 22 h per day, 5 days per week, to 60Co gamma radiation at dose rates of 1.36 to 12.64 x 10(-3) cGy/min for 23 weeks or 1.36 to 6.32 x 10(-3) cGy/min for 59 weeks. For deaths from all causes, linear dose-response curves were obtained with slopes (days of life lost/cGy) of 0.158 +/- 0.016 and 0.077 +/- 0.002 for 23- and 59-week exposures, respectively. These values were not significantly altered when the analysis was restricted to those mice dying with tumors (92% of the total) or to those presumably dying from tumors (82% of the total). Analysis of mortality rates showed that about 90% of the radiation-specific excess mortality was tumor related. The 59-week exposure series induced only a small increase in the number of days of life lost/cGy/weekly fraction over that induced by 23 weeks of irradiation, 4.53 +/- 0.15 compared to 3.64 +/- 0.36 days lost/cGy/weekly fraction. This lower than expected value for 59 weeks of exposure may signal the approach to the final linear, additive, injury term postulated from earlier studies at this laboratory with low-dose-rate, daily, duration-of-life 60Co gamma irradiation.

AN - 78927873; 2928472 AB - The radioprotectors WR1065 and WR151326, each at a concentration of 4 mM, protect against cell killing and mutagenesis at the hypoxanthine-guanine phosphoribosyl transferase (HGPRT) locus in V79 Chinese hamster fibroblast cells exposed to fission-spectrum neutrons (mean energy of 0.85 MeV) from the JANUS reactor. Significant protection against neutron-induced cell lethality occurred only when the radioprotectors were present during irradiation; e.g., D0's and n's were 82 Gy, 1.27 for control cells; 97 Gy, 1.51 for WR1065-protected cells; and 120 Gy, 1.00 for WR151326-protected cells, respectively. Mutation induction by JANUS fission-spectrum neutrons was linear over the dose range tested giving rise to a mutation frequency of 109.3 x 10(-6)/Gy. In comparison with 60Co gamma rays (mutation frequency 8.7 X 10(-6)/Gy), JANUS neutrons, at a dose rate of 24 cGy/min, were over 12 times more effective in inducing HGPRT mutations. Both WR1065 and WR151326 afforded protection against the induction of mutants by neutrons, even when they were administered up to 3 h after irradiation; i.e., mutation frequencies were 40.9, 48.8 and 68.6 X 10(-6)/Gy for WR1065 present during, present immediately after, or added 3 h after irradiation, respectively; and 61.7, 47.8, and 68.5 X 10(-6)/Gy for WR151326 present at the same times.

AN - 78859765; 2537141 AB - Studies were conducted to determine the possible involvement of DNA topoisomerase II (Topo II) in the induction of differentiation in two human promyelocytic HL-60 leukemia cell variants that are either susceptible or resistant to differentiation induced by phorbol-12-myristate-13-acetate (PMA), a protein kinase C activator. The acquisition of maturation markers and changes in the activity, level, and phosphorylation of Topo II were determined after treatment with either novobiocin, a Topo II inhibitor, or PMA. Novobiocin at 50-150 microM induced differentiation in the HL-205 cells but not in the HL-525 cells, although both cell types were equally susceptible to novobiocin-evoked cytotoxicity. In both cell types, novobiocin induced similar reductions in topoisomerase I activity but different reductions in Topo II activity. Treatment with novobiocin at 150 microM for 6 h or at 2 mM for 30 min resulted in a 4-fold or higher reduction in Topo II activity in the differentiation-susceptible HL-205 cells but not in the differentiation-resistant HL-525 cells. A differential response in Topo II activity was also observed after treatment with PMA. The novobiocin-evoked decrease in Topo II activity seems to be due to an enhanced enzyme proteolysis, whereas the PMA-elicited decrease in Topo II activity is associated with an increase in Topo II phosphorylation. 1-(5-Isoquinolinesulfonyl)-2-methylpiperazine, which is an inhibitor of protein kinases, including protein kinase C, diminished the novobiocin-elicited proteolysis of Topo II and the PMA-induced Topo II phosphorylation, as well as the decrease in Topo II activity and the acquisition of differentiation markers induced by either novobiocin or PMA. These results suggest that induction of differentiation in HL-60 cells by novobiocin or PMA is associated with a reduction in Topo II activity, mediated directly or indirectly by a protein kinase(s), perhaps protein kinase C.

AN - 78927625; 2713368 AB - Past difficulty in growing good crystals of cholera toxin has prevented the study of the crystal structure of this important protein. We have determined that failure of cholera toxin to crystallize well has been due to its heterogeneity. We have now succeeded in overcoming the problem by isolating a single isoelectric variant of this oligomeric protein (one A subunit and five B subunits). Cholera toxin purified by our procedure readily forms large single crystals. The crystal form (space group P2(1), a = 73.0 A, b = 92.2 A, c = 60.6 A, beta = 106.4 degrees, one molecule in the asymmetric unit) has been described previously [Sigler et al. (1977) Science (Washington, D.C.) 197, 1277-1278]. We have recorded data from native crystals of cholera toxin to 3.0-A resolution with our electronic area detectors. With these data, we have found the orientation of a 5-fold symmetry axis within these crystals, perpendicular to the screw dyad of the crystal.

AN - 78889265; 2922471 AB - The effects of the radioprotector 2-[(aminopropyl)amino] ethanethiol (WR-1065) on radiation-induced cell killing and mutagenesis at the hypoxanthine-guanine phosphoribosyl transferase (HGPRT) locus in V79 Chinese hamster cells under hypoxic or aerobic conditions were examined. Conditions of acute hypoxia were attained by gassing 10(6) cells in 1-ml volumes in individual glass ampoules for 2 min with nitrogen. Ampoules were then sealed and incubated at 37 degrees C for 60 min. Following this treatment, cell survival after irradiation as expected was significantly enhanced. The effect of acute hypoxia on the formation of HGPRT mutants by irradiation was also investigated. Mutation frequencies were determined with a 6-day expression time and corrected for the number of spontaneous background mutants. Although mutation induction was approximately linear as a function of radiation dose under most conditions tested, it was significantly reduced in cell populations made acutely hypoxic prior to irradiation. Protection against mutation induction was apparent and similar when cells were irradiated in the presence of the radioprotector, regardless of whether they were also hypoxic or aerated. If cells were irradiated in air and then made hypoxic, no significant protection was still observed. These results suggest that the antimutagenic effect of WR-1065 is not due solely to its ability to scavenge radiation-induced oxygen-free radicals, but rather that it may also modulate these effects through the scavenging of metabolically induced free radicals and/or the chemical repair of radiation-induced DNA lesions.

These films show 25 distinct sediment transport events, consisting of periods of bedform migration or sediment resuspension and occupying approximately 25% of the total record. Simultaneous observations of the surface winds showed that most of the sediment transport occurred during periods of northerly winds, implying that surface waves were the predominant mechanism for sediment remobilization at this location. A simple, empirical, sediment transport forecast model was used to determine threshold criteria for the initiation of bedload and resuspension of the local sediments (fine-medium sand). The model correctly predicted 85% of the total record when forced with estimates of the near-bottom wave orbital velocity calculated from the wind measurements and a parametric dynamical wave model. The critical wave orbital velocity for resuspension was found to be 17.8 cm/s. Estimates of the probability of sediment transport occurring on Indiana Shoals, determined as a function of wind speed and direction, were combined with climatological observations of wind conditions to estimate monthly probabilities of sediment transport. These probabilities are in agreement with previous forecasts based on historical observations of the Great Lakes wave climate.

The model assumed that the differences between sulphate and ammonium represented acidic sulphate and that the difference between nitrate and soil-derived calcium plus magnesium plus potassium represented acidic nitrate. Seasonal wet deposition (WD) chemical data is tabulated for each site. Acidic sulphate and nitrate (AS and AN) were considered the predominant proton source. The greatest part of the acidity was attributed to AS. The fraction of AS to proton WD value was 0.95 for east-central Tennessee site, 0.9 for the northeast Illinois site and 0.75 for the central Pennsylvania site. The AS fraction was 0.84, 0.66 and 0.71, respectively, for each site and for AN 0.35, 0.24 and 0.59, respectively. There are 56 references.

AN - 78535546; 3056628 AB - Sequential treatment of Syrian hamster embryo (SHE) cells with a chemical carcinogen followed by sodium fluoride (NaF) resulted in a higher yield of morphologically transformed cell colonies than treatment of the cells with carcinogen alone. For example, cells treated with benzo[a]pyrene (B[a]P; 3 micrograms/ml) for 3 days, then with NaF (25 micrograms/ml) for 4 days, exhibited a transformation frequency more than six times greater than that obtained by summing the transformation frequencies from cells treated with either B[a]P or NaF alone. This enhancement/promotion of cell transformation by NaF was only expressed after the cells had been pretreated with either direct-acting carcinogens or procarcinogens. Pretreatment of the cells with noncarcinogens or weakly-acting carcinogens or administration of NaF prior to treatment with the carcinogen failed to enhance the yield of transformation. Transformation was enhanced even when the NaF treatment was delayed for several days after the carcinogen treatment. However, the continued presence of NaF was necessary for maintenance of the increased level of transformation. Removal of NaF prior to termination of the assay resulted in a reversal of the transformed clonal morphologies to a normal phenotype such that the final yield of transformants was decreased, but was still greater than that observed after carcinogen treatment alone. A similar pattern for reversibility of the transformation enhancement also occurs for the widely recognized tumor promoter phorbol 12-myristate 13-acetate (PMA). Seven different SHE cell pools were tested for sensitivity to NaF promotion following carcinogen treatment. Although the response was heterogeneous, no carcinogen-treated cell pool was refractory to the NaF-induced enhancement. A second fluorocompound, sodium monofluorophosphate (NaMFP), was also found to enhance carcinogen-induced cell transformation in a manner resembling that of NaF.

Mice homozygous for each of the 4 ENU-induced protein variants were found to be viable and fertile, although the number of homozygous offspring from crosses between heterozygous carriers of one variant (ENU 2) was less than that expected for a nondetrimental trait. Two of the proteins altered by ENU-induced mutations were associated with the crude mitochondrial fraction, another was found predominantly in the microsomal fraction, and the fourth was associated with the mitochondrial, microsomal, and cytosol fractions.

AN - 78571540; 3201201 AB - We report here our initial observations on the growth and morphology, and developmental radiosensitivity of giant, multinucleated, osteoclast-like cells (MN-OS) generated through in vitro cultivation of hematopoietic progenitor-enriched canine bone marrow samples. Maximum cell densities of 5.5 x 10(3) to 6.5 x 10(3) MN-OS per cm2 of growth area were achieved following 10 to 14 days of culture at 37 degrees C. Acute gamma irradiation of the initial marrow inocula resulted in significant, dose-dependent perturbations of MN-OS formation, growth, and development. Attempts to estimate radiosensitivity of MN-OS progenitors from canine marrow yielded a range of Do values from a low of 212 cGy measured at six days of culture to higher values of 405 to 542 cGy following 10 to 22 days of culture. At the intermediate times of culture (10 to 14 days), the radiation-induced responses were clearly biphasic, reflecting either (a) the presence of multiple subpopulations of MN-OS progenitors with varying degrees of radiosensitivity or (b) the inherent biphasic nature of MN-OS development involving early progenitor cell proliferation followed by maturation and subsequent fusion. Morphologically, MN-OS generated from irradiated marrow inocula appeared only marginally altered, with alterations expressed largely in a biphasic, dose-dependent fashion in terms of smaller cell size, reduced number of nuclei, increased expression of both surface microprojections, and a unique set of crystalloid cytoplasmic inclusions. Functionally, MN-OS appeared to be impaired by irradiation of marrow progenitors, as evidenced by failure to initiate resorptive attachments to devitalized bone spicules in vitro.

AN - 78395631; 3410694 AB - Some areas of radiation genetics still contain gaps of knowledge, as these studies lost priority when the emphasis in experimental mutagenesis shifted toward the effect of chemical mutagens. This shifted emphasis, however, was accompanied by the development of a better understanding of genetic injury at the molecular level. At the opposite end of the spectrum, more attention was paid to estimates of the direct health costs of the genetic burden in humans and the capacity to make prenatal diagnoses, and to consider reasonable clinical and biochemical intervention. Although, as yet, there are no completely reliable direct methods to estimate the radiation-induced mutation rate in humans, we have come to rely upon data from experimental animals to predict event frequency and extrapolate from these data to predict human health consequences. What will the future offer? Certainly, we should develop a better understanding of molecular genetic damage and, possibly, a better extrapolation model for predicting mutation rate, but many aspects of expected health consequences may remain elusive. We still may have to rely upon (1) an inadequate human population genetic baseline, (2) sometimes arguable perceptions of man-mouse extrapolation models, (3) changing perceptions of gene-environment interactions, and (4) changing levels of short-term selection pressure against detrimental mutations.

VII. Effects of 60 once-weekly exposures. AN - 78362681; 3406372 AB - A total of 6316 B6CF1 mice were exposed to 60 equal once-weekly doses of 0.85-MeV fission neutrons (0.033 to 0.67 cGy per weekly fraction) or 60Co gamma rays (1.67 to 10 cGy per weekly fraction) and were observed until they died. The mean aftersurvival times showed that the dose-response curves for both neutron and gamma-ray exposures were indistinguishable from linear over all doses except the highest neutron dose. The relative biological effectiveness (RBE) for neutrons, calculated as the ratio of the initial slopes of the dose-response curves, was about 20 for both males and females. Essentially the same value was obtained by a number of other analyses of the data. Virtually all of the radiation-specific excess mortality could be attributed to tumors; after decrementation of the population for nontumor deaths, the value of the RBE was not significantly changed.

AN - 78308876; 3390811 AB - Previous investigations in this laboratory have provided evidence that histochemically detectable altered hepatocyte foci and hepatic tumors appearing in rats given a single neonatal treatment with a low dose of carcinogen followed by chronic dietary phenobarbital administration are developmentally independent. The present investigation further evaluates developmental relationships among these lesions. Altered hepatocyte foci were divided into two subclasses consisting of foci that were detectable by histochemical as well as by hematoxylin-eosin staining [designated hist(+)/morph(+) foci] and those foci that were detectable solely by histochemical staining [designated hist(+)/morph(-) foci]. The developmental and phenotypic properties of the hist(+)/morph(-) foci, hist(+)/morph(+) foci, and hepatic tumors were compared in rats initiated once neonatally with different doses of diethylnitrosamine and promoted with dietary phenobarbital from weaning. The morph(+) and morph(-) lesion subclasses were distinguishable on the basis of several developmental characteristics. Hist(+)/morph(+) foci were present at low frequency until at least 150 days after initiation. Although the development of hist(+)/morph(-) foci was essentially complete at that point, the rate of appearance of hist(+)/morph(+) increased significantly. The diethylnitrosamine dose response of the hist(+)/morph(+) foci followed the histochemical marker patterns of the tumor lesion class more closely than that of the hist(+)/morph(-) group. The rates of expression of the hist(+)/morph(+) foci increased with the increasing level of histochemical complexity, whereas the rates of expression of the hist(+)/morph(-) foci groups were inversely correlated to their complexity level. Although the average focus size or diameter in the hist(+)/morph(+) groups was greater than that of the hist(+)/morph(-) foci, the focus growth rates of morph(+) and morph(-) subsets matched for histochemical phenotype were comparable. The complexity level and individual marker distribution patterns of the hist(+)/morph(+) focus class were more similar to tumor patterns than to the distribution patterns of the hist(+)/morph(-) lesion class. The results suggest the following. (a) The development of lesion classes with successively greater deviation from normalcy does not occur via lineal progression from less to more deviated forms within a given lesion class. The three lesion classes appear to develop independently, with the developmental characteristics of each lesion class determined at the time of initiation.(ABSTRACT TRUNCATED AT 400 WORDS) JF - Cancer research AU - Peraino, C AU - Carnes, B A AU - Stevens, F J AU - Staffeldt, E F AU - Russell, J J AU - Prapuolenis, A AU - Blomquist, J A AU - Vesselinovitch, S D AU - Maronpot, R R AD - Biological, Environmental, and Medical Research Division, Argonne National Laboratory, Illinois 60439.

AN - 78293101; 3388440 AB - Female mice were given nutrient-sufficient, purified diets containing cadmium at either 0.25, 5, or 50 ppm, as described in the accompanying publication. One-half of the females were bred for 6 consecutive 42-day rounds of pregnancy/lactation (PL mice); remaining females were non-pregnant controls (NP mice). PL mice and NP controls were sacrificed after 1, 2, 4, or 6 consecutive rounds of pregnancy/lactation. At all levels of dietary cadmium and after all reproductive rounds, kidney cadmium concentrations were 2-5-fold higher in PL than NP mice. After 6 rounds of reproduction, the mean concentration of cadmium in the kidneys of PL mice exposed to dietary cadmium at 50 ppm was 115 micrograms Cd/g kidney, close to the critical concentration for cadmium-induced renal damage (200 micrograms/g). No consistent increases in the concentrations of amino acids, protein, or cadmium in urine were observed in the NP or PL mice in our study, indicating that cadmium-induced renal dysfunction had not yet appeared. Very small increases in kidney concentrations of zinc and copper were observed with large increases in kidney cadmium concentrations. Threshold cadmium concentrations below which the concentrations of zinc and copper were relatively constant and independent of cadmium concentration were identified; they were 7.2 micrograms Cd/g kidney for zinc and 13 micrograms Cd/g kidney for copper. In this study, cadmium-induced decreases in bone-mineral content occurred in the PL mice exposed to cadmium at 5 and 50 ppm (see accompanying publication). Data presented here indicate that the latter bone changes occurred in the absence of cadmium-induced renal dysfunction of the type that results in increased aminoaciduria/proteinuria. They suggest that the bone disease of Itai-Ital patients may also have started prior to the onset of this type of renal dysfunction.

One-half of the females were bred for 6 consecutive 42-day rounds of pregnancy/lactation (PL mice); remaining females were non-pregnant controls (NP mice). PL mice and NP controls were sacrificed after 1, 2, 4, or 6 consecutive rounds of pregnancy/lactation. No consistent, cadmium-dependent decreases in body weight, femur calcium content, or calcium/dry weight (Ca/DW) ratio occurred among the NP mice during the 252 days of cadmium exposure. In contrast, significant, cadmium-dependent decreases in body weight (3-11%), femur calcium content (15-27%), and Ca/DW ratio (5-7%) occurred in the multiparous mice exposed to 50 vs 0.25 ppm Cd. In addition, among the PL mice, the effect of cadmium was dose-dependent, with femur calcium contents decreasing significantly as the cadmium exposure level increased from 0.25 to 5 then 50 ppm Cd (P less than 0.05). Results demonstrate that dietary cadmium exposure had a greater effect on the skeletons of dams exposed to cadmium during the stresses of pregnancy and lactation than in non-pregnant controls. The results provide evidence that the combination of cadmium exposure and multiparity may have played a role in the etiology of Itai-Itai disease in Japan.

AN - 78357330; 3403645 AB - A permeation absorber was developed and experimentally evaluated for sampling and preconcentrating vapors of a primary aromatic amine into a small volume (ca. 0.1 ml) of a liquid extractant that can be directly injected into a chromatograph or other analytical instrument. Starting with 1-l or 4-l samples containing dry or humidified air (0, 7% or 35% relative humidity) and 0.5-5 parts per million by volume of aniline, the measured collection efficiency (fraction of aniline recovered in the extractant) ranged between 60 and 100% when the samples were recirculated 3-6 times. For a single-pass non-recirculating mode, the collection efficiency is calculated to be 40-50%. The degree of preconcentration is directly proportional to the volume V of the sampled air. The collection method is simple and fast and should also be applicable to the sampling and preconcentration of other hazardous air contaminants.

AN - 78188462; 3162823 AB - To evaluate the role of protein kinase C in the cellular maturation processes induced by phorbol diesters, we examined the biochemical activity of protein kinase C from HL-205, a cell variant from the human promyelocytic HL-60 leukemia that is susceptible to differentiation induced by phorbol 12-myristate 13-acetate, and from HL-525, an HL-60 variant that is resistant to such an induction. The activities of protein kinase C from the two cell types differed in their requirements for the cofactors Ca2+ and lipids. These enzyme activities also differed in their abilities to phosphorylate protamine and a series of four oligopeptides. We suggest that the differences in vitro in the activities of protein kinase C between HL-205 and HL-525 cells, especially in their substrate specificity, are closely related to the different phosphorylation patterns induced in vivo by phorbol 12-myristate 13-acetate in these cells. We also suggest that these differences may be responsible for the different susceptibilities of the two cell types to maturation induced by phorbol diesters.

AN - 78195236; 3360604 AB - From the results of serial measurements of body 226Ra activity in 13 former luminous dial workers 30-60 y after relatively brief periods of intake of luminous compounds in adolescence or young adulthood, we determined the postmenopausal rate of elimination of Ra in percent of contemporary body Ra content per year. This rate was negatively correlated with the "reduced x-ray score," a measure of radiation osteonecrosis observed radiographically in the 13 subjects (r = -0.85, P less than 0.001). The clearance rates of subjects retaining low Ra activity were greater than predicted by retention models. We conclude that for those members of the Ra-exposed population under study for health effects at our institution who sustained the lesser degrees of macroscopic skeletal damage, present estimates of skeletal absorbed dose are systematically low, by at most a factor of 2.

III. Frequencies of abnormal sperm and reciprocal translocations measured during and following long-term weekly exposures. AN - 78161420; 3352636 AB - Male B6CF1 mice were exposed to either fission neutrons or 60Co gamma-rays at once-weekly doses approaching occupational levels for periods up to 60 weeks. Both during and after the irradiation sequence, the mice were screened to determine the incidence of abnormal epididymal sperm and of reciprocal chromosome translocations in metaphase spermatocytes. Abnormal sperm frequencies equilibrated with dose/week by 10 weeks and also showed an additive nonlinear seasonal increment. The relative biological effectiveness (RBE) for these damages is 12 +/- 1. After exposures ended, sperm frequencies in gamma-irradiated mice quickly returned to near-normal levels. Neutron-irradiated males showed a significantly elevated level of abnormalities for approximately 30 weeks--a paradoxical finding--as no clear evidence of cumulative injury was seen during exposure. When assayed at 10 and 25 weeks of exposure but not later, translocation frequencies demonstrated an increment, significant in the neutron series, attributed to irradiated spermatocytes. Dose-response analysis with cumulative dose up to the 60-week maximum gave an RBE of 45 +/- 10. Post exposure, the incidence of translocations subsided slightly, but the RBE remained above 30.

AN - 78253331; 3132111 AB - Body radon daughter contamination reflects relative individual respiratory exposures to radon daughters; counts can be related both to household radon levels and to lung cancer risk factors such as sex and tobacco smoking. Radon daughters were counted by gamma spectroscopy from 180 adult residents of eastern Pennsylvania. A seven-position, 35-min scan was conducted in a mobile body counter, generally during afternoon or evening hours. Track-etch detectors for household radon were distributed, and were recovered from 80% of the subjects. Over 75% of the population had environmentally enhanced radon daughter contamination. House radon levels were strongly related, as anticipated, to radon daughter contamination in the 112 subjects for whom both sets of measurements were available (p less than .001); basement measurements were as strongly related to personal contamination as were living area measurements; bedroom measurements were slightly more strongly correlated. Both sex (p less than .02) and cigarette smoking (p less than .01) significantly modified the relationships, after nonlinear adjustment for travel times. Using a logarithmic model, a given house living-area radon level was associated in females with body contamination by radon daughters 2-3 times that in males. Nonsmokers had 2-4 times higher levels of contamination than smokers. Results are for the total of internal and external contamination, these being highly correlated in preliminary experiments. Time usage and activity patterns of the subjects are believed to be important in explaining these findings, and may become important variables in radon risk assessment.

DNA damage caused by X and gamma irradiation, measured by alkaline elution methods, is the same in both cell types, whereas the P3 cells are about two times more sensitive (as measured by Do ratios of the final survival curve slope) to the lethal effects of these radiations than are the V79 cells. Human P3 cells are also more sensitive to the lethal effects of fission-spectrum neutrons than V79 cells. Survival experiments with split radiation doses and hypertonic salt treatment indicate that both P3 cells and V79 cells can recover from radiation-induced damage efficiently.

AN - 78535303; 3191537 AB - The antitumor agent gilvocarcin V (GV) is photoactivated to a genotoxic form by low fluences of near-ultraviolet radiation. Activation of GV by monochromatic 450-nm radiation causes two specific DNA changes in human P3 cells in culture as shown by alkaline elution techniques: single-strand breaks (i.e., alkali-labile sites plus frank strand scissions) and DNA-to-protein covalent bond crosslinks. When GV is present with the cells during irradiation, the yields of these damages are increased. Fluence and concentration studies show that the induction of both DNA lesions occurs at unusually low concentrations of drug and fluences of radiation. Both breaks and crosslinks are readily detectable after exposure to less than 100 kJ m-2 of 405 nm-radiation at a GV concentration of 7.5 X 10(-9) M. These results indicate a possible potential for use of GV in human tumor photochemotherapy.

AN - 78348145; 3401981 AB - The thermal acrophase for the circadian oscillation of core temperature in Charles River male rats fed ad libitum and entrained by light (12 hr dim light and 12 hr bright light) (DL 12:12 hr) occurred near the middle of the dim phase on a control diet of 30% protein. Dietary phenobarbital (0.25%) caused an increase in amplitude of the oscillation (from 0.7 degrees to 1.2 degrees C) and a phase-angle difference (psi-advance) between the zeitgeber and the biological oscillation of about 32 degrees, equivalent to an advance in the thermal acrophase of 2.1 hr in the steady-state. Food consumption was monitored continually and was nearly the same in the two groups; however, animals on the control diet ate around the clock, albeit at a greater rate during dim light than during the bright light phase, whereas rats on phenobarbital started to eat earlier and confined their feeding almost exclusively to early dim phase. This pattern of increase in amplitude of the thermal oscillation and of feeding closely resembling programmed feeding, persisted in phenobarbital-treated animals even in the absence of a dim light-bright light (DL) zeitgeber for eight days. Similar behavior was seen in rats entrained by illumination cycles of 17 hr of dim light and 7 hr of bright light, but with this reduced phase ratio for the zeitgeber, few psi-shifts occurred, and these were smaller than those induced in the group receiving 12 hr of dim light and 12 hr of bright light.

Such underestimation is due, in part, to their reliance on the static extrapolation of past trends, ie, an atheoretical statistical method that pays scant attention to the behavioral, medical, & social factors contributing to mortality change. It is suggested that a "multiple cause-delay model" more realistically portrays the effects on mortality of the presence of more favorable risk factors at the population level. Such revised assumptions produce large increases in forecasts of the size of the elderly population, & have a dramatic impact on related estimates of population morbidity, disability, & health care costs. 2 Tables, 6 Figures, 73 References.

As is the case for many limnological properties, the major source of variation is the nonhomogeneous (i.e., dependent on position) distribution of the sampled variable. A quantitative estimate of the expected accuracy of the volume- weighted mean is determined empirically from calculations applied repeatedly to random selections of sample data. Analysis of data from five cruises, conducted using a network of 31 stations, shows that a network of 22 stations would provide a whole-bay volume-weighted mean accurate to within 10% of that determined using the full network with 80% confidence. A network of 23 stations would achieve these same accuracy and confidence limits when applied to a model in which Green Bay is divided into four geographic zones and the volume-weighted mean calculated for each zone. The nonparametric method offers an alternative to the classic analysis of variance method for evaluation of limnological sampling designs.

This surface contains binding sites for c-type cytochromes. The approximate two-fold structural symmetry is evident in the folding of the L and M subunits of the reaction center on this surface. In spite of this, the distribution of charged residues shows a marked deviation from symmetry. One group of charged residues is distributed symmetrically. For this group, equivalently charged residues are located at symmetry-related positions on both L and M subunits. However, charged residues are also found at positions which do not follow the two-fold symmetry. Seven charged residues appear on the L and M subunits at positions which do not have a charged residue at the corresponding position on the other subunit. These symmetry-breaking charged residues appear in a single region, or "patch", on the surface of the reaction center. We propose that this patch may function as a site for cytochrome c docking. A model of the Rb. sphaeroides cytochrome c sub(2)-reaction center electron transfer complex has been built. Preliminary energy calculations show that this configuration is at least a local energy minimum.

AN - 81086802; 2823131 AB - Chinese hamster ovary cells and human P3 teratocarcinoma cells were exposed to superoxide anion (O2-) generated by the addition of potassium superoxide (KO2). DNA from the cells was examined by alkaline elution techniques for the production of single-strand breaks, as well as for the production of double-strand breaks and DNA-protein cross-links. It was demonstrated that KO2 produced only single-strand breaks in DNA in both cell lines, in a dose-dependent manner. The number of breaks was reduced by the prior addition of a metal chelator, indicating that some of the breaks may have been caused by the metal-catalyzed (Fenton reaction) reduction products, hydrogen peroxide or hydroxyl radical Catalase almost completely inhibited break induction by O2-, evidence for a role of hydrogen peroxide. The results of this study indicate that O2- and its reduction products can damage intracellular mammalian DNA.

AN - 81108312; 2890430 AB - Relative frequencies of diethylnitrosamine (DEN)-initiated foci of altered hepatocytes appearing in response to promotion by either dietary phenobarbital or a topically applied coal-derived organic mixture (CDM) were investigated in male and female rats. The focus population was examined for two histochemical markers, elevated gamma-glutamyl transpeptidase [GG(+)] and iron exclusion [FE(-)], giving rise to 3 detectable focus phenotypes, i.e., GG(+) foci, FE(-) foci, and GG(+)/(FE(-) foci. Frequencies of the 3 phenotypes were quantitated through the use of serial frozen sectioning and computer-assisted image analysis. In agreement with our prior observations, cutaneous exposure to CDM or dietary phenobarbital promoted the expression of DEN-initiated foci. However, the current data showed that this promoting effect of CDM occurred only in females and was restricted to foci with the GG(+)/FE(-) phenotype. Dietary phenobarbital, on the other hand, promoted both the GG(+) and GG(+)/FE(-) phenotypes and was effective in both males and females, although a sex-related differential in the promoting efficiency of phenobarbital was also observed. The pronounced heterogeneity in the responses of the 3 focus phenotypes suggests that each phenotype is the consequence of a specific type of genomic alteration with a specific capacity to undergo phenotypic expression in response to a given promoting stimulus.

Rainwater (20 litres) was acidified, filtered, degassed and treated with powdered potassium permanganate crystals. A combination of evacuation, ultrasonic agitation and helium sparging (VUS treatment) was used to remove the oxygen produced by the permanganate oxidation of hydrogen peroxide. Oxygen was converted to carbon dioxide in a helium stream at 600C over a bed of graphite and platinum. The resulting carbon dioxide was cryogenically removed from the closed system to allow for subsequent measurements of oxygen-18. Rainwater samples from Illinois, Michigan, New York and North Carolina during the summer of 1985 were analysed by this method. The isotopic results on the peroxide, sulphate and water indicated that 40 per cent of sulphate precipitation was derived from peroxide oxidation of sulphur dioxide in the atmosphere.

Techniques used to address each of these elements were defined using literature examples. Emphasis was placed on moving the evaluation of models, particularly those in publications, towards more quantitative or objective measures of calibration and validation. However, such objective measures were only meaningful in context with all the performance elements. There are 37 references.

Adsorbable (aniline, phenol) and non-adsorbable (ethanol) inhibitors were added to assess the contribution of the adsorption of inhibitory compounds to the improvement of nitrification performance. The adsorption of nitrification inhibitors by powdered activated carbon could improve nitrification rates very significantly in unacclimated activated sludge cultures. The results of the study could not be accounted for by other mechanisms suggested to explain the nitrification enhancement.

Methods for assessing the likely impacts of such facilities on the human environment have been increasingly questioned. Many technical experts view the problems as primarily sociopolitical. Utilizing social impact assessment (SIA) during the environmental assessment process can address some of the complex problems related to siting such facilities. Various suggestions are offered as to how SIA can be used to deal more effectively with issues relating to hazardous waste facilities.

The phenols used were: 4-chloro-m-cresol, 2,4-dimethylphenol, 2,4-dinitrophenol, 4-nitrophenol, pentachlorophenol and 2,4,6-trichlorophenol. With the exception of chlorinated phenols, little if any adsorbed on to dolomite at temperatures of 5 and 22C and at concentrations from 0.1 to 10 mg per litre. Phenol degradation was not detected. It was concluded that phenols, dispersed where they could leach and contaminate dolomite groundwater aquifers, could pose a health and environmental hazard. Unlike dolomite, chemical sorbents did adsorb phenols, and therefore could be used for groundwater cleanup.

The study verified earlier experimental observations that the chemistry of acidification-related solutes, such as sulphates, in precipitation water could be significantly altered in the ground link between the aquatic systems of the Adirondack catchments and the atmosphere. Bacterial redox cycling of sulphates in the soils of the catchments might be the mechanism by which lake water quality is affected. Another possible mechanism is ion exchange, in which the soil strata containing chemically-fixed sulphates not in equilibrium with sulphates in the atmospheric water act as an ion exchange column.

Colloidal organic carbon was separated from the water samples by ultrafiltration. Distribution coefficients of ambient plutonium (III, IV) were found to be inversely related to dissolved organic carbon. Equilibration studies indicated that equilibrium was reached in about 7 days regardless of water source or oxidation state of the plutonium. The distribution coefficient was found to be independent of sediment concentration in water and adsorption/desorption was reversible over a 7 day period. A mechanism postulating the existence of a single type of binding site on the surface of the solid phase and two soluble complexes containing 1 and 2 molecules of colloidal organic carbon per plutonium atom was proposed.

They were analysed for radium-226 with a view to developing a method for predicting the radium concentration in well waters. Detailed tables are provided showing cities with less than 3.0 pCi radium-226 per litre, and the amount of radium-226 in the municipal water supplies. The study identified 177 communities with a total population of 1,442,000 who were exposed to radium-226 concentrations exceeding 3 pCi per litre; of these, 599,000 were exposed to concentrations exceeding 5 pCi per litre. Large deviations of radium-226 (3.8-18 pCi per litre) were found in nearly identical wells in close proximity. Radium-228 concentrations determined in 140 samples ranged from 0.3-32 pCi per litre. No correlation was found between radium-226 and radium-228 concentrations and a large scale survey of radium-228 was recommended.

This was due to a large, irreversible decrease in the swelling capacity of the bentonite. Relatively little mineralogical change was observed. The mechanism by which swelling capacity was reduced was thought to be either hydrolysis of exchangeable cations, or an attack on the octahedral layer accompanied by release of aluminium into interlayer positions, or oxidation of ferrous iron. Whatever the mechanism, the ability of a bentonite barrier to retard groundwater flow in high level nuclear waste repositories was open to doubt.

Although the system has not been widely employed for synthetic purposes, it is thought to possess unique oxidizing and fluorinating capabilities. An elucidation of the reaction with emphasis on the production of hydrogen peroxide and oxygen is presented together with experimental results obtained from the monitoring of hydrogen peroxide production in the reaction of fluorine with aqueous solutions. Further experiments designed to determine the kinetics of absorption of fluorine into aqueous solution are also described. Results presented showed that both fluorine and hypofluorous acid reacted with water to produce steady state concentrations of hydrogen peroxide if allowed to proceed for sufficient time consistent with a mechanism involving the intermediate formation of hypofluorous acid. An order of magnitude estimate for the rate of reaction was obtained which was considerably greater than the analogous rates for the heavier halogens. Refinement of the techniques described should permit the evaluation of a variety of rate constants for the reaction of fluorine with aqueous substrates.

Simulation studies showed that significant annual variations, in average total phosphorus concentrations, would be expected as a result of year-to-year changes in both loading and transfer process. Annual measurements of lake contaminants would facilitate both model refinement and better estimates of the inter-basin transfer coefficients for any parameter of interest.

Fish exposed to the first two conditions fed and grew as though they were acclimated to the maximal temperatures experienced, and accumulated more PCB than fish exposed to a constant temperature. Total food consumption or growth was the best correlate of PCB concentration in the whole fish while lipid content of muscle was the best correlate of PCB concentration in muscle. About 10 per cent of the total uptake was the result of direct uptake from the water.

Its equations and boundary conditions can be solved by a finite-difference method in a staggered grid. It has been applied to the simulation of salt intrusion during low flow conditions in Chesapeake bay, U.S.A. The predicted results compare well with observations and confirm that high salinity water is advected upstream in the lower layer by gravitational circulation. The lower-layer water is mixed upward, resulting in a salinity increase through the water column. Simulation of a hypothetical flow reduction suggests significantly increased salinity in the upper bay and an enhanced bottom water intrusion over the whole bay.

Its behaviour in natural water systems and assimilation by man AN - 13865153; 198303814 AB - The largest impact on water quality owing to an influx of soluble plutonium would be in rivers. In the Mississippi river, having a discharge rate of 500,000 billion litres per year, the concentration of plutonium could exceed the speculative MPC of 7 x 10 to the minus 13 Ci per litre but would very probably not exceed the present value of 5 x 10 to the minus 9 Ci per litre. The probability of all the plutonium in a nuclear reactor entering and dissolving in a body of water such as Michigan lake is considered extremely low, but if it were to happen, the level of plutonium in the water could be nearly three orders of magnitude lower than the present MPC for drinking water.

Zinc, at concentrations much lower than those previously reported to be toxic, significantly reduced zooplankton populations. The relation between differences in bioaccumulation of metals by different species and the observed changes in community structure are discussed.

Zinc-65 and cadmium-109 were used in 21 radio-tracer experiments to evaluate the kinetics of sorption of the metals by total seston and various components of the plankton community. The first series of experiments evaluated the time-series sorption by total seston and selected particle size fractions and the transfer of the metals to crustacean zooplankton by food ingestion and/or direct sorption from the water. The abundance of phytoplankton and detritus controls the concentrations of particle-bound zinc and cadmium. The second series determined both the sorption by seston and the effects on plankton of toxic levels of the metals, in in situ trials. In the third series, 4-hour experiments evaluated seasonal trends in the sorption by seston exposed to potentially toxic concentrations. The impact of toxic levels of phytoplankton may reduce sorption and removal by sedimentation, thus increasing dissolved levels.

It was shown that atmospheric inputs are the main source of cadmium and sedimentation to the main removal mechanism. A simplified mathematical model was used to investigate the effects of the increasing input rates . The results show that even a modest increase in the annual input could lead to deleterious effects on zooplankton communities within a few decades.

The bias caused by longitudinal succession is removed by normalizing diversity indices and species richness values for river size .

The results show that some plutonium, and more americium, can be removed from the sediments by resin extraction under aerobic conditions at about pH 7.0. These extractions are not correlated with extractable iron and manganese. No significant differences were observed in the extractability of the elements under anoxic or oxic conditions. Field observations indicated that neither plutonium nor americium is resolubilized into the overlying waters during stratification and it is recommended that care be taken in extrapolating laboratory results to field conditions.

The dissolved plutonium in the water from below the sediment/water interface was principally in the reduced form (oxidation state III or IV) while the dissolved plutonium in the overlying water was chiefly in an oxidized form (oxidation state V or VI). The plutonium adsorbed to the solid phase was almost entirely in the reduced form. The concentration of the reduced plutonium in the interstitial water decreased with depth in each core in direct proportion to the decrease in plutonium concentration in the solid phase. Concentration ratios for the reduced plutonium between the solid and aqueous phases indicated that this form does not become appreciably more soluble after burial up to depths of 30 cm in these sediments, hence the rate at which the element moves through the interstitial water by chemical diffusion or advection must be extremely slow.

The dirt batch consisted of a pile 25 m high, 1.8 ha in area of pyrites, rock, shale, other mineral particles removed by density separation, and it was adjoined by a slurry pond. Results from preliminary surveys indicated the presence of very acid leachate with high concentrations of sulphate and dissolved solids, issuing from the base of the pile, but this had not affected nearby residential wells possibly owing to the calcareous nature of the underlying strata. Following regrading of the pile and covering with topsoil from a borrow pit on the site, the observation wells showed noticeable increases in acidity and inorganic salts which persisted for 1-2 years and then declined. Since 1979 there has been a marked improvement in groundwater quality which is now approaching that of neighbouring areas. JF - Quality of Groundwater (edited by van Duijvenbooden.

The adsorption mechanism is described by a linear equilibrium isotherm. The model allows for a variety of boundary conditions eg infiltration, drainage or evaporation. The solution to these equations is obtained through a Galerkin-type finite-element method using linear quadrilateral and triangular elements. The model was tested by comparing predicted values with analytical solutions and experimental results for transient flow. The use of the model is illustrated with reference to the migration of hypothetical three-membered radionuclide decay chains during leaching from the tailings pond of a typical uranium mill.

I. Theory AN - 13902418; 198100603 AB - A two-dimensional, finite element model for the migration of ground water contamination has been developed and validated. The Upstream (Upwind) finite element model has been applied to the solution of the mass transport equation, first in the two-dimensional domain, and subsequently extended to the transient case . It was chosen in preference to the Galerkin model to avoid overshoot and oscillations when applied to field problems, though artificial numerical damping of the solute front was introduced.

The tests were carried out in a fermenter with a glass recycle loop, designed to minimize water and substrate requirements, maintain relatively uniform biofilms and low concentration gradient by high recycle flow/ feed flow ratios and keep wall shear stress independent of residence time. It is shown that an increase in biofilm thickness corresponds to increased frictional resistance and to an increase in the calculated sand roughness. Increased frictional resistance is characterized by an induction period at small biofilm thickness followed by a rapid increase in thickness after a critical thickness has been reached. While the influence of tube constriction on frictional resistance is low, a significant effect is caused by the filamentous nature of the biofilm. The effect of Reynolds number on friction for a tube with attached biofilm is similar to that for a tube with rigid rough surface. JF - Journal of Hydraulics Division.

The carboys were filled with lake water collected from different depths using a special sampler, dosed with cadmium at levels from 0.2 to 5.0 ug per litre, and incubated under water by attachment to a weighted cable suspended from a marker buoy. Zooplankton abundance was influenced both by cadmium concentrations above 1.6 ug per litre and by light intensity (depth) during 3-week incubation periods. Other effects on community structure were apparent at cadmium concentrations down to 0.2 ug per litre. The relative benefits of submerged translucent and opaque enclosures for short- and long-term experiments in a lake environment are discussed. JF - Aquatic Toxicity (edited by Eaton.

The former has a radioactivity level so high that cooling is required for the first few years of storage. Management of such material has involved five strategies: (1) storing the liquid waste in underground double-walled steel tanks in concrete vaults; (2) conversion of liquid waste to a dry powder or granules; (3) immobilization of dry waste in glass or crystalline ceramic material; (4) placing the immobilized waste in corrosion-resistant metal canisters; (5) isolation of canisters in a mined repository within a deep, stable geologic structure. Groundwater interaction with repositories is a potential problem, being the only credible mechanism by which radioactive material from high-level waste may be fed back to the biosphere. Only about 50 per cent of low-level nuclear waste is derived from the U.S. nuclear-power industry, and strategies for management include the following six steps: (1) the incineration of organic waste; (2) conversion of liquid to solids; (3) reduction of the volume of solid waste; (4) packing of solid waste in leak-proof containers; (5) isolating the packaged waste in earth-covered trenches; (6) monitoring of the disposal area for integrity of waste isolation. The technical solutions for the management and disposal of nuclear wastes are considered to be well developed: delays in implementation in the U.S.A. are related to sociological and political considerations.

The toxicity of cyanide containing effluents to fish and invertebrate species in various stages of development has recently been studied, and methods of detection and continuous monitoring of cyanide in treated effluents reported. Evidence that cyanide exposure may impair the reproductive capacity of rainbow trout was reported.

The numerical methods used exhibited an acceptable degree of confidence when compared with analytical solutions and experimental results. For the case of nitrogen (as in the multi-solute system of an ammoniacal agricultural fertilizer problem) the chemical reactions between ammonium, nitrite and nitrate are described by first-order kinetics with linear adsorption for ammonium. Non-linear adsorption for the case of a single solute is also discussed. An immediate practical outcome of the research is the demonstration of the effect of the layered system on the final outlet concentration - of importance to those involved in waste disposal on the land.

Recorded and calculated dilutions at the intakes, and observations of environmental mechanisms, together with reconstruction of the worst case episode of pollution expected, were obtained for future use in planning remedial action at the filtration plant to mitigate the effects of diminished water quality.

AN - 74459285; 318515 AB - The 238Pu concentrations of various tissues were measured for seven species of freshwater fish from an ecosystem containing elevated levels of 238Pu. The highest levels of 238Pu were found in the gastrointestinal tracts and gills, while the lowest levels were found in muscle tissue. A rapid uptake of 238Pu was observed for hatchery bluegills introduced into this system. High plutonium concentrations in the gastrointestinal tracts and gills suggest that these organs are potential uptake sites. The presence of 238Pu in certain tissues (liver, gonads, bone, and muscle) indicates that there is translocation of 238Pu from the uptake sites.

The effect was measured in terms of the rate of increase of the population, a parameter which incorporates the effect of cadmium toxicity on both mortality and reproduction. Behaviour of Daphnia under natural conditions for up to 14 days' exposure was accurately predicted by laboratory measurements.

Both incidence and mean number of metacercarial cysts were significantly greater in the fish collected from Goose Creek. Greater nutrient loads in Goose Creek compared to the Tongue River, resulting in greater biotic community productivity with accompanying macrophytic growth, was concluded responsible. Incidence and mean number of cysts were greater on the dace from the Tongue River site downstream of the Goose Creek-Tongue River confluence compared to the Tongue River site upstream of the confluence. Nutrient inputs from Goose Creek increasing Tongue River productivity below the confluence were deemed responsible. Though there was a statistically significant difference in parasite burdens between sites, within site comparisons of log weight-log length relationships of parasitized and nonparasitized dace indicate that Neascus rhinichthysi burdens had no apparent effect upon the fish.

Scanning electron micrographs show that copepod fecal pellets, collected from Lake Michigan, contained fractured specimens of 21 species of diatoms. Few intact diatoms were observed and many frustules were reduced to small fragments during ingestion by the copepods. The peritrophic membrane surrounding the pellets is composed of polysaccharides, one of which is chitin. This membrane is broken down by bacterial decomposition in 6-14 days as the pellets settle at an average velocity of 4.7 m d super(-1). As a result, pellets released near the surface in water more than 70 m deep do not transport diatom fragments directly to the sediment. In a large proportion of Lake Michigan the transport of diatoms to the sediments via pellets originating near the surface is unlikely, since about 60% of the lake is >70 m deep.

The concentration in the 0-0.5-cm sediment layer varied from 6.31 10 super(5) to 3.71 10 super(7) frustules g dry wt super(-1). The annual deposition of frustules to the sediment ranged from 7.00 10 super(3) to 5.20 10 super(5) frustules cm super(-2) yr super(-1), <5% of the estimated annual diatom production based on average annual diatom standing crop, turnover rate, and depth of the euphotic zone. The vertical distribution of frustules in every core showed a logarithmic decrease of at least two orders of magnitude in a depth equivalent to 80-100 years B.P. Scanning electron photomicrographs of frustules from the sediment show evidence of dissolution. Dissolved silica concentrations in deep and interstitial water support the conclusion that diatom frustules are dissolving in both the water column and sediment. The permanent sediment is probably not a major sink for particulate biogenic silica in Lake Michigan.

This pilot study was performed on Lake Michigan at the Point Beach Nuclear Power Station (Two Creeks, Wisconsin) on 28 October 1971. Reduction of fish distribution and temperature data from both day and night plume series showed striking diurnal changes in fish orientation. Many schools of fish were observed during the day series, while, at night, only individual fish were observed. The depth distribution of fish also differed between day and night: during the day, observed schools were deeper than individual fish, whereas at night, the individuals were at shallower depths. During both series: (1) fish were more numerous in the upstream side (relative to current) of the plume; and (2) fish were more abundant in the cooler areas of the plume (<15C.) Limitations of the technique include: (1) the restricted sampling volume of the fish locator; (2) possible bias due to fish avoidance of the vessel; and (3) the need for supplementary effort to determine species and size information.

AN - 81306753; 11898837 AB - The late effects of protracted exposure to low levels of external radiation continue to be a matter of operational concern in long-range space flight. Studies have been carried out on young adult mice exposed to daily levels of 60Co gamma irradiation ranging from 0.3 to over 30 R day-1. The lowest level is comparable with the occupational maximum permissible dose for the atomic energy industry. There is little evidence of life shortening at that level, but as exposure increases, there is an exponential decline in life expectancy. The life-shortening coefficient is approximately 4 days/100 R accumulated or 4% R-1 day-1. When life-shortening is < or = 15%, all of the increased mortality can be attributed to radiation-induced increases in death rates from neoplastic diseases, including various forms of leukemia and pulmonary tumors. Age-specific death rates for mice dying of all other causes remain the same as the controls throughout life, at the lowest doses. A non-neoplastic disease component of excess mortality rate emerges at 6 R day-1 and above. The risk of death from all and specific causes following single exposures compared with protracted lifetime irradiation shows a clear effect of protraction. Leukemia death rates are reduced by a factor of 5 or more at all daily exposure levels below 20-30 R day-1. Risks for other causes of death are also reduced, but to a variable degree.

Study of these data suggests that the concentration of radium, thorium, and uranium by tropical marine algae is controlled by two mechanisms: 1) ion-exchange or coprecipitation of the ion with the calcium carbonate matrix, and 2) complex formation with either the protein nitrogen or some other component of the organic fraction. Radium (and possibly thorium) apparently is concentrated by both mechanisms, the dominant one depending on the phylum. For the Rhodophyta and the highly calcified Chlorophyta it is the former and for the Phaeophyta the latter. Uranium is concentrated by the first mechanism.

A careful calibration was done, using a 226Ra source in 0.5 mm platinum, in an almost scatter-free environment which permitted the derivation of accurate corrections for scatter and air attenuation. Calibrations calculated from the physical measurements of the ion chambers are compared with the experimental calibrations. Values of Wbeta for air, and muscle gas and of tauRa are derived.

AN - 76348743; 17387925 AB - Synchronized Chinese hamster cells were irradiated in air and in nitrogen at various points in the cell cycle. The irradiations were carried out after flushing with air or nitrogen with the medium removed from the mono-layer of cells. Under these conditions the dose-modifying factor, or oxygen enhancement ratio, was between 2.0 and 2.3 for survival in asynchronous cells. The variation in x-ray sensitivity evident as the cell progresses through its cycle was not differentially affected by its state of oxygenation at the time of irradiation. The x-ray age-response curves for irradiation in air and in nitrogen were similar at each point, except for the dose-modifying factor. This was true not only for the cells of a normal short generation time (10 hours) subline of the V79 line but also for a longer generation time (with longer GC period) subline derived from a "small colony". The variation in radiosensitivity as the cell progresses through its cycle must therefore be due to factors other than change in oxygen tension within the cell. The fact that the same variation in x-ray sensitivity with age exists for hypoxic cells as for well-oxygenated cells has a bearing on the radiotherapy of tumors which contain cells at low oxygen tensions.

Restoration of degraded ecosystems and soils represents a target sink for offsetting rising atmospheric CO sub(2) levels by increasing carbon sequestration in soils. The Conservation Reserve Program (CRP) and other initiatives to halt land degradation after cessation of cultivation present opportunities to assess the C sequestration potential of restoration practices. Our aim is to study what key ecosystem and climatic components exert the largest leverage for these lands to be sustainable C sinks. When considering controls on ecosystem C cycling, biodiversity has the potential to be a strong biotic influence. Invasive species can disrupt ecosystem processes by exhibiting functional characteristics which are distinct from their native counterparts. Invasive species, while affecting nearly all ecosystems, may pose a particular threat to restorations and impact rates of C accrual. We measured net ecosystem production (NEP) at a 18 years-old restored tallgrass prairie using the eddy covariance technique coupled to biometric estimates of biomass and soil C in a two year study where climatic conditions and plant species dominance varied. In 2005, the prairie restoration was a strong C sink with a NEP 438 gCm super(-2), despite a pronounced spring drought. In 2006, with above normal precipitation, a Melilotus alba dominance dramatically reduced NEP when compared to 2005. The loss of ecosystem functional diversity that resulted from the dominance of the invasive M. alba led to a 42% reduction in the length of the photosynthetically active season, as compared to the previous year. These results suggest that understudied biotic limitations to NEP may outweigh the effects of more commonly studied abiotic limitations. Ecosystem models and management strategies should consider biotic limitations to NEP in grasslands in order to maximize long term C sequestration of restorations and CRP management practices.

An Analysis of Various Energy Supply Scenarios and Their Implications for Future Air Pollution Emissions AN - 17433363; 4643509 AB - Poland's move to restructure and modernize its economy in preparation for joining the European Union will go hand in hand with major changes in the way the country produces and consumes energy. A projected increase in energy consumption must be balanced with domestic and international environmental obligations to reduce source emissions. As signatory to both the European Second Sulfur Protocol, as well as the Kyoto Protocol, the country has agreed to significantly reduce its emissions of sulfur dioxide (SO sub(2)) and greenhouse gases by 2010, This study uses the ENergy and Power Evaluation Program (ENPEP) to analyze several energy policy scenarios and to identify those that meet the requirements of both protocols. The results show that Poland will be able to meet the SO sub(2) emission requirements under all scenarios. However, meeting the Kyoto obligations will strongly depend on which reference year Poland will ultimately consider as binding. JF - EMISSION INVENTORY: LIVING IN A GLOBAL ENVIRONMENT - VOLUME 2.

Many of the PBTs are semivolatile organic compounds (SVOCs) that are present in the atmosphere almost entirely in the vapor phase. The rate of transfer of a SVOC can be predicted from meteorological conditions and the physicochemical properties of the chemical and the surface. We use a conventional resistance scheme to describe the dry deposition of vaporphase SVOCs to terrestrial surfaces. Micrometeorological formulas are applied to describe aerodynamic resistances above the surface. Pathways to uptake at the ground and in vegetative canopies are depicted with several resistances that are affected by variations in air temperature, humidity, solar irradiance, and soil moisture. The effects of soil moisture variations on the uptake of gases through vegetative plant leaf stomata are assessed by using the relative available soil moisture. Uptake of the SVOCs by the waxy outer cuticles of vegetative plant leaves is evaluated through results of laboratory studies published in the scientific literature and theoretical considerations. Model simulations of the dry deposition of SVOCs to various land use types will be presented.

Deriving surface conductances from AVHRR data AN - 16091641; 4200073 AB - This paper describes methods to couple the reflectance-resistance model developed in Paper I with the normalized difference vegetation index (NDVI) data from the advanced very high resolution radiometer (AVHRR) on satellites over the eastern United States. A land use data set was also employed to determine appropriate model parameters suitable for describing differences in characteristics of light scattering and leaf resistance among different plant canopies, especially between forests and short canopies (crop and grass, etc.). As a case study, the biweekly averaged NDVI data for a year with normal precipitation (1987) and a drought year (1988) were selected for analysis to maximize differences in vegetative conditions and canopy conductance for pollutant transfer. The satellite-derived NDVI over the region had a much lower value in summer 1988 than in summer 1987. The depression was especially large for cultivated areas and rangelands, but it was much less significant for forested regions. The NDVI data were incorporated into the model to calculate the regional distribution of canopy conductances for pollutant transfer to the earth's surface.
