AN - 75586282; 8432645 AB - Recent efforts to incorporate greater anatomical and physiological realism into biokinetic models have resulted in many cases in mathematically complex formulations that limit routine application of the models. This paper describes an elementary, computer-efficient technique for implementing complex compartmental models, with attention focused primarily on biokinetic models involving time-dependent transfer rates and recycling. The technique applies, in particular, to the physiologically based, age-specific biokinetic models recommended in Publication No. 56 of the International Commission on Radiological Protection, Age-Dependent Doses to Members of the Public from Intake of Radionuclides.

Sara Title III's properties are reviewed: its advantages include increasing cooperation among federal agencies & decentralizing dissemination of information regarding accidental release of chemical hazards. Yet, the CSEPP experience indicates the need for greater cooperation with federal, state, & local governments in developing emergency plans, improving community outreach, & resolving tort liability issues.

AN - 75551240; 8380576 AB - Using site-directed mutagenesis, it was previously found that mutation of the individual residues Tyr13, Tyr22, Ile23, or Leu26 in the amino-terminal domain or of the highly conserved Leu47 in the carboxyl-terminal domain of human epidermal growth factor (hEGF), resulted in significantly decreased receptor binding affinity. In the present study, the single-site hEGF mutants Tyr13-->His, Tyr22-->Asp, Ile23-->Thr, and Leu26-->Gly were genetically combined with the Leu47-->Ala hEGF mutant to produce a series of double-site mutant hEGF gene products having alterations simultaneously at two sites, in separate domains, within the same hEGF molecule. Similarly, the combination of the single-site hEGF mutants Tyr13-->His and Ile23-->Thr generated a double-site mutant having two mutations within the same domain. Finally, combination of the hEGF mutation Ile23-->Ala with Leu23-->Ala altered two side chains located in close proximity within the large beta-sheet region of the molecule. Analysis of the relative receptor binding affinities, determined by radioreceptor competition assays of the various single- and double-site hEGF mutants, demonstrated that mutation at any one site does not substantially alter the effect of mutation at the second site in the molecule. The cumulative effect of simultaneous mutations on relative receptor binding affinity confirms the importance of residues, including those in the large amino-terminal beta-sheet, in receptor binding, and indicates that each of the separate sites functions essentially independently in the interaction of the hEGF molecule with its receptor.

The data did not reveal the timing of initiation of this denudation but apatite fission-track age analysis on a sample of Crashsite Group quartzite from Springer Peak suggested that the initiation of this denudation event may be found in the Heritage Range. To test this hypothesis, the authors visited the Heritage Range in Nov. and Dec. 1992. Samples of Jurassic granite were also collected from the Whitmore Mountains and Pirrit Hills in late Dec. 1992 and early Jan. 1993. Fission-track data from the Ellsworth Mountains and other ranges of Ellsworth-Whitmore Mountains crustal block will help to further constrain not only the uplift and formation of these mountains but also the tectonic evolution of West Antarctica during, and subsequent to, the break-up of Gondwana.

AN - 76156087; 8280373 AB - Treatment of mice with hepatic carcinogens, including CCl4, has been shown to rapidly enhance the transcription of endogenous murine leukemia virus-related proviral sequences in the liver. To understand the mechanism for this transcriptional stimulation, we used nuclear protein preparations from mouse livers to perform DNase I protection analyses and identified nuclear protein binding on approximately 20 individual sequences within the regulatory regions of the long terminal repeat (LTR) of a polytropic-class endogenous provirus clone. From 3 to 144 h after treatment with CCl4, the livers of FVB/N mice were analyzed for specific nuclear protein binding to the LTR DNA. Three to nine hours after CCl4 treatment, decreased protection was seen at potential regulatory cis-elements throughout the LTR, including specific sites within the putative negative regulatory element (located 5' of the consensus enhancer sequences) and the 3' terminal portion of the polytropic class-specific enhancer-like inserted sequence element and around the CCAA(C/T) box in the promoter region. In addition, by 3-6 h after treatment, a transient increase in protection activity for the transcription initiation site occurred. The loss of cis-element protection expanded to other binding sites and became most marked by 48 h after treatment. As the regenerating liver recovered, the nuclear protein binding activities for these LTR sequences also recovered, but protection at the TATAA and transcription initiation sites remained deprotected at 144 h after treatment. Nuclear protein protection of other sites, particularly in the conserved LTR enhancer sequences, was minimally affected by CCl4 treatment. Three nuclear protein binding sites that showed rapid CCl4-induced kinetic changes were homologous to the consensus sequence for the binding of the transcription factor families MEF-2, HNF-1, and C/EBP. The complex kinetic changes in factors that may contribute to the rapid and transient induction of endogenous retroviral gene expression in the liver after CCl4 exposure are discussed.

AN - 75914560; 8358168 AB - Two loci [l(7)5Rn and l(7)6Rn] defined by N-ethyl-N-nitrosourea (ENU)-induced, prenatally lethal mutations were mapped by means of trans complementation crosses to mice carrying lethal deletions of the albino (c) locus in Chromosome (Chr) 7. Both loci were found to map to the subregion of the Mod-2-sh-1 interval that contains the eed (embryonic ectoderm development) locus, eed has been defined by the inability of embryos homozygous for certain c deletions to develop beyond the early stages of gastrulation. Evidence for at least two loci necessary for normal prenatal development, rather than one locus, that map within the eed interval came from the observation that two prenatally lethal mutations, 3354SB [l(7)5Rn3354SB] and 4234SB [l(7)6Rn4234SB], could complement each other in trans, but could not each be complemented individually by c deletions known to include the eed locus. A somewhat leaky allele of l(7)5Rn [l(7)5Rn1989SB] was also recovered, in which hemizygotes are often stillborn and homozygotes exhibit variable fitness and survival. The mapping of the loci defined by these mutations is likely to be useful for genetic, molecular, and phenotypic characterization of the eed region, and mutations at either locus (or both loci) may contribute to the eed phenotype.

From March-April 1993, we used the modified Bowen ratio (MBR) method to measure emission rates of mercury over a floodplain contaminated with mercury near Oak Ridge, TN. The mercury emission rates measured from contaminated EFPC soils using the MBR method during early spring show that (1) in all cases, the contaminated soils acted as a source of mercury to the atmosphere with source strengths ranging from 17 to 160 ng m (super -2) h (super -1) ; and (2) the strengths of mercury emissions can be greatly influenced by the combined effects of surface soil temperature, residence time of air masses over the source area, and turbulence conditions. The mercury fluxes measured in a controlled flow chamber indicate that contaminated soils can exhibit up to an order of magnitude higher emission rates of Hg under conditions of elevated soil temperature, soil structure disturbance, and high turbulence.

The soil was characterized using well established test procedures and was artificially contaminated with lead. Three forms of lead contamination were studied. The soil was contaminated with the soluble salt, NaNO (sub 3) , and with two less soluble forms of lead: PbSO (sub 4) and PbCO (sub 3) . The soil was also contaminated with both PbNO (sub 3) and naphthalene to explore the possible effects of an organic substance on both the retention and release of lead from the study soil. The efficiencies of six washing solutions to remove lead from the contaminated soils were then investigated via lab-scale batch washing experiments. Unlike current soil washing practices, all particle size fractions were washed and recovered in these experiments. Hydrochloric acid and EDTA yielded lead removal efficiencies from 60-98%. The broad range in removal efficiencies obtained is largely due to the various forms of lead contamination which were examined. The experiments involving the lead nitrate in the presence of naphthalene yielded lead removals which were greater than those obtained from washes without an organic contaminant.

Each of these phases will require site surveys to determine type and quantity of hazardous and mixed wastes. It is generally recognized that these required survey and monitoring efforts cannot be performed using traditional chemistry methods based on laboratory evaluation of samples from the field. For that reason, a tremendous push during the past decade or so has been made on research and development of sensors. This report contains the results of an extensive literature search on sensors that are used or have applicability in environmental and waste management. While restricting the search to a relatively small part of the total chemistry spectrum, a sizable body of reference material is included. Results are presented in tabular form for general references obtained from data base searches, as narrative reviews of relevant chapters from proceedings, as book reviews, and as reviews of journal articles with particular relevance to the review. Four broad sensor types are covered: electrochemical processes, piezoelectric devices, fiber optics, and radiochemical processes. The topics of surface chemistry processes and biosensors are not treated separately because they often are an adjunct to one of the four sensors listed. About 1,000 tabular entries are listed, including selected journal articles, reviews of conference/meeting proceedings, and books. Literature to about mid-1992 is covered.

Contaminants in the many waste sites on the ORR include heavy radioactive isotopes as well as many organic and inorganic compounds. The locations, geometry, and contents of many of these waste sites are reasonably well known, while others are poorly known, and some may be unknown. To better characterize the known sites and locate and characterize additional environmentally hazardous sites, a two-phase aerial survey of the ORR was begun in April, 1992. Phase I, which began in April, 1992, consisted of aerial radiation, multispectral scanner, and photographic surveys. Phase II, which began in November, 1992 and is described in this presentation, consisted of a helicopter electromagnetic (HEM), magnetic, and radiation survey. Targets of the survey were both man-made (drums, trench boundaries, burn pits, well heads) and geologic (fractures, faults, karst features, geologic contacts). The Phase II survey has three components: testing, reconnaissance, and high-resolution data acquisition. To date, the testing and reconnaissance data acquisition have been completed, and part of the data have been processed. They indicate that: 1) magnetic and HEM data are complementary, and do not always highlight the same anomaly; 2) under favorable circumstances, helicopter magnetometer systems are capable of detecting groups of 4 or more 55-gallon drums at detector altitudes of 15 m or less, 3) HEM data provide data which compare favorably with surface data collected over burial trenches, 4) well casings seem to be related to magnetic monopole anomalies, as would be expected, 5) Changes in EM and magnetic anomaly character are related to lithologic changes and might be used to track contacts between known outcrops.

The formations recording this tectonic evolution are, from oldest to youngest: the Iron Springs (and eastern equivalents), Kaiparowits, Canaan Peak, Grand Castle (new informal name), Pine Hollow, and Claron formations. The Santonian to lower Campanian(?) upper part of the Iron Springs and mid-to-upper Campanian Kaiparowits formations represent synorogenic, fluvial sedimentation derived from the Sevier fold and thrust belt. The Iron Springs Formation received sediment from Precambrian to Upper Paleozoic strata exposed in the Wah Wah and Blue Mountain thrust sheets of southwestern Utah. The upper Campanian(?) to lower Paleocene Canaan Peak Formation was deposited in an east-to-northeast-directed, braided fluvial system. Petrographic and geochemical analysis of volcanic and siliceous clasts indicate that the Canaan Peak and Kaiparowits formations were derived from the Jurassic Delfonte Volcanics of southeastern California and the Mississippian Eleana Formation of southern Nevada. The early Paleocene Grand Castle formation represents an east- to southeast-flowing braided river system. Clast and sandstone lithologies indicate that the Grand Castle formation had the same provenance as the Iron Springs Formation. Conglomerate of the Grand Castle formation overlaps the easternmost Sevier thrust faults, suggesting a post-Sevier origin. The lower Pine Hollow Formation records active Laramide partition of the foreland basin associated with the development of the Johns Valley anticline and possibly the Circle Cliffs uplift. Fluvial, deltaic, and lacustrine deposits of the Claron Formation overlap paleotopographic highs of the Pine Hollow basin and indicate cessation of Laramide deformation by the middle Eocene.

Problems in properly assessing the stratigraphy of the Paunsaugunt Plateau have resulted from the lack of recognition of a major fault (Sand Pass Fault) along the western margin of the plateau east of the Sevier fault. Also critical to stratigraphic interpretation is the formational assignment of a thick, pebbly conglomerate and overlying fine-grained beds immediately underlying the Canaan Peak or Claron formations. These beds were originally interpreted as belonging to the Kaiparowits Formation, but more recent interpretations include the conglomerate in the upper part of the Straight Cliffs Formation and assign the overlying beds to the Wahweap Formation. Compositional analysis of conglomerate samples provides no information bearing on the stratigraphic equivalency of the unit but does suggest that conglomerates considered to be in different stratigraphic units by various workers probably represent the same conglomerate. Comparison of sandstone compositions of the uppermost Cretaceous rocks on the Paunsaugunt Plateau to those of the Wahweap and Kaiparowits formations on the Kaiparowits Plateau favors assignment of these beds to the Kaiparowits Formation. Stratigraphic analysis indicates that structural controls were exerted during the Cretaceous along the trends of Tertiary faults. Differential subsidence between these trends may have resulted in unique stratigraphic sequences being deposited in adjacent sub-basins.

The HAI is a quantitative index that allows statistical comparisons offish health among data sets. Index variables are assigned numerical values based on the degree of severity or damage incurred by an organ or tissue from environmental stressors. This approach has been used to evaluate the general health status offish populations in a wide range of reservoir types in the Tennessee River basin (North Carolina, Tennessee, Alabama, Kentucky), in Hartwell Reservoir (Georgia, South Carolina) that is contaminated by polychlorinated biphenyls, and in the Pigeon River (Tennessee, North Carolina) that receives effluents from a bleached kraft mill. The ability of the HAI to accurately characterize the health offish in these systems was evaluated by comparing this index to other types of fish health measures (contaminant, bioindicator, and reproductive analysis) made at the same time as the HAI. In all cases, the HAI demonstrated the same pattern offish health status between sites as did each of the other more sophisticated health assessment methods. The HAI has proven to be a simple and inexpensive means of rapidly assessing general fish health in field situations.

Elevated EROD activities in males, diminished liver estrogen receptor binding capacities in females, and decreased plasma testosterone and increased liver lipids in both sexes were highly correlated with elevated body burdens of total PCBs. Alterations in DNA repair activity at the most highly-contaminated site were also suggested by the results of a DNA alkaline-unwinding assay. These and related findings from preliminary studies of fish health in Lake Hartwell strongly suggest that environmental PCB contamination has quantifiable and potentially very damaging physiological consequences for exposed fish populations.

EPA protocols for conducting reproduction toxicity tests using carnivorous mammalian wildlife, specifically mink (Mustela vison), have previously been developed and are being used to assess reproductive and physiological effects in mink fed fish collected on the ORR and containing elevated concentrations of PCBs and mercury. Reproductive and physiological effects in mink groups fed diets composed of 25, 50, and 75% fish collected from contaminated streams located on the ORR are being compared to effects observed in control mink groups fed diets composed of 75% fish collected above the ORR or diets composed of 75% ocean fish. Results are being used to (a) assess individual and population level adverse effects in mink consuming fish from streams on the ORR, (b) develop remedial action goals, and (c) assess the efficacy of remedial actions.

Fish population health was determined by applying a suite of biological indicators ranging from the molecular to the population level of biological organization. Effects on fish observed at the biomolecular level included increased DNA strand breaks and at the biochemical level, elevated liver detoxification enzymes. Histopathological analysis revealed severe damage to gill tissue and several incidences of thyroid carcinomas in spleen tissue. Reproductive dysfunction in some female fish was evidenced by a high percentage of atretic oocytes and reduced serum estradiol levels. In addition, fish populations demonstrated an abnormal size distribution and age structure. Anomalies observed in this fish population that are of the most concern relative to human health are the genotoxic responses (DNA damage), potential carcinogenic effects (thyroid carcinomas), and endocrine dysfunction (altered steroid hormones). Vital statistics data collected by the Tennessee Department of Health reveal that cancer deaths in the county which includes the contaminated river are much higher than in any other East Tennessee county. However, epideminogical studies for residents that live along the river are needed before a possible relationship can be established between aquatic ecosystem health and human health.

Viable biomass, taxonomic composition, and physiological status are readily assayed through the analysis of pigments and phospholipid ester-linked fatty acids (PLFA) in solvent extracts. The pigments are recovered after a 4 h one-phase chloroform-methanol extraction in the dark; they are then analyzed by high pressure liquid chromatography (HPLC) with a reverse-phase C sub(18) column and a diode array detector. The extraction is continued for an additional 20 h to fully recover lipids. The lipids are fractionated on silicic acid columns, and the polar lipid fraction trans-esterified in mild alkaline methanol with analysis of PLFA by capillary GC/MS. Tiles were sampled 2, 5, 7, 14, and 28 days following their transfer from reference to impacted stream sites. Eight major pigments and one pigment degradation product were identified by HPLC. Incremental sum of squares dendrograms of percent total pigments and percent total PLFA correctly clustered samples to each of three streams and allowed differentiation of reference and impacted sites in each stream. Differentiation was primarily due to shifts in species composition as evidenced by changes in the percentages of pigments and PLFA common to certain types of algae.

The reports provide a unique resource for researchers engaged in environmental and human health risk assessment. Both reports contain data from published sources as well as from unpublished studies submitted by The Soap and Detergent Association member companies. The reports review information on product chemistry and analysis; biodegradation; environmental levels, including fate and distribution; aquatic toxicity; and human safety. Recently developed analytical techniques for the extraction, separation, detection, and measurement of nonionic surfactants and their metabolites in environmental samples are described. Results of biodegradation studies performed with a variety of test systems as well as results of field studies at wastewater treatment plants are tabulated. Comparisons of environmental levels of APE in U.S. rivers with results of acute and chronic aquatic toxicity tests are included. The available information on the toxicity and irritation potential of AE and APE surfactants includes data from in vitro, mammalian, and human studies; reviewed are studies on oral and dermal toxicity, eye and skin irritation potential, and carcinogenicity, genotoxicity, and developmental/reproductive assays.

Since 1985, twice-yearly electrofishing surveys have been conducted at sites immediately downstream of each facility. These surveys indicated that increases in abundance and species richness of fish communities were associated with the implementation of various remedial actions such as new waste water treatment facilities, closure of waste disposal ponds, and waste stream dechlorination. Increased abundance (as measured by density) was the initial indicator of fish community recovery. Density increased from 0-0.1 fish/m super(2) to 3.0-29.7 fish /m super(2) at the four stream sites. Species richness also increased from 0-5 species per sample to 4-12 species per sample at the four sites. The increases in species number involved only fish species that were not sensitive to environmental disturbance. Fish community responses corresponded with treatment start-up dates; the responses generally were incremental, as increments of treatment occurred. Although recovery was evident at each site, the extent of recovery varied and did not match density and species richness patterns in the fish communities of suitable upstream or offsite reference sites.

Preliminary toxicity tests using medaka and redbreast sunfish (Lepomis auritus) embryos had suggested that effluent from the mill has an adverse affect on fish embryo development. More intensive medaka embryo-larval tests conducted on numerous sites along a gradient upstream and downstream of the mill now suggest that municipal wastewater inputs also contribute substantially to the observed embryo toxicity. Embryo survival decreased and the incidence of obvious developmental abnormalities increased significantly immediately downstream of the mill. However, toxicity continued to increase with increasing distance from the plant as discharges from a series of municipal sewage treatment plants were added to the stream. Subsequent tests have further reinforced these findings demonstrating that the medaka embryo-larval test may be used as an indicator of environmental perturbations in rivers and streams receiving either industrial or municipal effluents.

However, relatively little is known about the factors affecting contaminant uptake and loss from periphyton. For example, it is unclear whether live biomass or precipitated Manganese and ion oxides are more important in sorption dynamics. To investigate factors influencing metal uptake by periphyton, we preformed a series of experiments using ceramic tiles (with accumulated periphyton and metal oxides) which had been previously placed in Oak Ridge streams. Tiles were placed in laboratory chambers containing stream water and added nickel ion. Both periphyton and metal oxide surfaces sorbed significant quantities of nickel. On an areal basis, periphyton surfaces were observed to sorb more nickel than metal oxide surfaces. The similar capacities of these surfaces suggest that periphyton can be a significant sorbent of nickel. A light gradient experiment demonstrated an increase in nickel uptake with light that was similar to a photosynthesis-irradiance relationship, suggesting a photosynthetically-mediated sorption mechanism. These experiments have important implications for predicting the uptake of heavy metal ions by periphyton in streams.

It is now imperative to improve the quality of ERAs being conducted. ORNL and the MPCA have learned a few lessons which have contributed to a progressively improving methodology for assessing ecological risks. Following are a few key components which have contributed to this improvement: 1) open dialogue between the regulators and the regulated community which helps ensure that the ERA product is acceptable to all parties; 2) diagrammatic representation of the conceptual site model, clearly outlining the sources of contamination, the exposure pathways, and the receptors ensures that all key components of the assessment are considered; 3) identification of appropriate endpoints. Ideally, assessment endpoints would address the most important ecological effects which are those at the higher levels of ecological organization. However, toxicity and field measurement endpoints are organism level. This discrepancy must be reconciled; and 4) risk managers, the public and other interested parties must be able to understand the risk characterization results. Because most RI reports present human health and ecological risk assessments in separate chapters or volumes, it is advantageous to present the combined results of both assessments. This would allow the evaluation of the implications of both assessments simultaneously. JF - 14th Annual Meeting (SETAC) - Ecological Risk Assessment: Lessons Learned? -- Abstract Book.

The only nationally consistent SCC currently recommended by the EPA is for residential sites contaminated with PCB'S. The development of further SCC for remediation of other organic pollutants at hazardous waste sites is being considered by the EPA. Evaluations of the utility of SCC must consider variations in geographically distributed environmental factors, and not just traditional inter- and intra- species response variations. In order to assess this geographic variation we evaluated the influence of variable site environmental factors on risks to songbird survival associated with plausible SCC for organic pollutants. Exposure was characterized by modeling the effects of regional soil quality characteristics (i.e. pH, cation exchange capacity, porosity, and percent organic matter) and regional climate characteristics on pollutant transport, transformation, and bioavailability. Ecological effects were evaluated by modeling pollutant uptake and bioaccumulation with a soil-to-earthworm-to-bird food chain model. The integration of the exposure profile and the ecological effects into a risk estimation was completed by aggregation of the distributions of pollutant effects and exposure.

The emphasis is placed on expert system design and knowledge representation. One of the most challenging and research-intensive steps was the identification of the key geochemical characteristics that would enable the expert system to identify salient features of any user-defined geochemical composition. Moreover, developing a system to create geochemical interpretations similar to those written by expert geochemists proved to be difficult. Important geochemical characteristics and their interrelationships which were "discovered" during knowledge acquisition and conceptualization are presented. These characteristics have been organized and documented within the expert system to emulate the skills of an expert geochemist. Examples of expert system-generated analyses are presented.

Standard static 24 h tests were, therefore, carried out on the relative toxicities of different forms of chlorine (hypochlorite ion, hypochlorous acid, monochloramine, and dichloramine), using C. dubia fed with a mixture of digested trout chow, yeast and Cerophyl. Chloramines were very toxic with an LC50 value of less than 0.02 mg per litre, but free chlorine in the form of hypochlorous acid and hypochlorite was much less toxic. The free chlorine reacted very rapidly with the food supplied, so that the standard test measured the toxicity of chlorinated food rather than of free chlorine. In static tests without food, free chlorine showed greater toxicity but still decayed rapidly in the test solution. Continuous-flow tests showed free chlorine to be more toxic than the chloramines. The estimated LC50 values for hypochlorous acid and hypochlorite ion in these tests (0.005 and 0.006 mg per litre, respectively) were considerably lower than the U.S. EPA 4 d average water quality criterion for chlorine of 0.011 mg per litre.

The basic features of NOM breakthrough, namely extended tailing and rapid decline when input was terminated, which had been observed in laboratory columns, were also observed in the field, and retardation of NOM in the field agreed with predictions from laboratory results. There was evidence of fractionation of NOM sub-components during transport, with more hydrophilic components of lower molecular weight being more mobile than larger hydrophobic components. Over a 2 week period, however, the solid and solution phases reached apparent steady state, resulting in unretarded transport of even hydrophobic macromolecular components. NOM could contribute to the transport in groundwater of contaminants capable of binding to NOM. There are 43 references.

Many toxicants, particularly those of low water solubility, tended to be accumulated by periphyton, thus retarding the net movement of toxicants downstream. Eventually the toxicants were released by ion exchange, excretion, or cell lysis, and transported downstream where they might be re-absorbed by periphyton; this process had been described as spiralling. The presence of large numbers of grazing snails such as Elimia reduced the thickness of the periphyton, thus limiting the food available to other organisms, such as chironomid larvae which were readily consumed by organisms in higher trophic levels, so transferring the toxicants into the food web. Elimia was consistently absent from contaminated sections of the streams examined.

This concept is illustrated with an example using water chlorination as a reference material. The application of the results to assess remedial needs is discussed. If the bioassay procedures yielded large hazard indices, the samples should be analysed to determine whether any constituents were inconsistent with existing guidelines.

The effects of natural organic matter, fulvic acid, and polyglutamate on the oxidation process were also investigated. At high partial pressures of oxygen, natural organic matter had little effect on the rate of oxidation, which showed first-order reaction with respect to concentration of ferrous iron and an oxidation half-time of 20 minutes. At low dissolved oxygen, the rate of oxidation showed apparent zero-order behaviour, with an oxidation half-time of 40 h; however the rate of oxidation under these conditions was enhanced by addition of organic matter. Oxidation occurred through 2 different pathways. There are 32 references.

There were marked differences in scale strontium concentrations at high spatial resolution between fish from the 2 areas. There was a peak in strontium concentration near the scale focus of M. saxatilis collected in the freshwater Roanoke river. In addition, in fish from Roanoke river and Albemarle Sound there were spatial variations across annuli that might reflect movements between fresh and saline water. The laser ablation technique can sample deep in tissues as material is progressively vaporized. This showed that there was typical strontium profile with depth through the estuarine scales with a peak of unresolved significance near the inside surface.

When groundwater ages were calculated using measured tritium and helium isotope values the resulting age gradient was in close agreement with the average vertical groundwater velocity calculated using the location of the mid-1960s tritium peak. A recharge rate of 0.16 m per year was computed for the site. This agreed to within about 5 per cent with the value based on the measured depth of the tritium peak and on 2-dimensional modelling.

Life history theory provides the framework for selecting representative species, and in combination with information on important environmental characteristics, it provides the framework for predicting the results of model simulations. Individual-based modelling offers a promising tool for integrating and extrapolating our mechanistic understanding of reproduction, growth, and mortality at the individual level to population-level responses such as size-frequency distributions and indices of year-class strength. Based on the trade-offs between life history characteristics of striped bass Morone saxatilis, and smallmouth bass Micropterus dolomieu and differences in their respective environments, a prediction was made that young-of-year smallmouth bass are likely to demonstrate a greater compensatory change in growth and mortality than young-of-year striped bass in response to changes in density of early life stages and turnover rates of zooplankton prey. This prediction was tested with a simulation experiment. The pattern of model results was consistent with expectations: by the end of the first growing season, compensatory changes in length and abundance of juveniles were more pronounced for smallmouth bass than for striped bass. The results also highlighted the dependence of model predictions on the interplay between density of larvae and juveniles and characteristics of their zooplankton prey.

Firstly, ECNICI spectra were able to differentiate the PCB components from the non-PCB components, secondly, the number of ECNICI analyses was minimal (identification being carried out using 1 one set of ion abundance measurements) and thirdly, mass spectral data could be treated in a consistent manner, this minimizing ambiguities. In this study 8 Aroclors (1016, 1232, 1242, 1248, 1254, 1260, 1262 and 1268) were analysed by ECNICI for a range of concentration levels.

The equations were based on the Boussinesq approximation for subsurface flow. The assumption of a long thin aquifer was unnecessary. The required parameters, relating to slope, drainable porosity, saturated hydraulic conductivity and layer thickness, were easily measured. The most accurate predictions of drainage volume arose from linearization of the Boussinesq equation by using an average height of the water table which varied with time and was maximal at the beginning of drainage, decreasing to zero in infinite time. The equations were tested with data from a laboratory flume: their predictions were least accurate towards the end of the drainage period.

The strategy demanded the setting of explicit environmental goals, their operational definition, then the selection of toxicity tests and an extrapolation model to estimate risks. Factor, empirical statistical and mechanistic mechanical models are explained. These were applied to the case of the toxicity of a chloroparaffin compound to the fathead minnow. The results are tabulated: they were not all comparable because the endpoints differed. The proposed approach would make the process of extrapolation more systematic and scientifically defensible.

Field experiments were conducted between April and October in a warm humid region of the south-eastern U.S.A. The results confirmed that atmometers were useful monitoring instruments for the estimation of potential evaporation. Their advantages included small size, portability,low internal thermal mass, low cost, and the ability to integrate the effects of radiation, air temperature, humidity and wind speed into one direct measurement of potential evaporation.

AN - 73389003; 1334433 AB - Phosphoribulokinase (PRK) is one of several chloroplastic enzymes whose activity is regulated by thiol-disulfide exchange via thioredoxin. Activation entails reduction of an active-site disulfide bond between Cys16 and Cys55. Bifunctional cross-linking reagents have been used to approximate the interresidue distance between Cys16 and Cys55, an issue which impinges on the relative conformational states of the activated and deactivated forms of the enzyme. Spinach PRK is rapidly inactivated by stoichiometric levels of 4,4'-difluoro-3,3'-dinitrodiphenyl sulfone (FNPS) or 1,5-difluoro-2,4-dinitrobenzene (DFNB), which span 9 and 3.5 A, respectively. ATP, but not ribulose 5-phosphate, retards the rate of inactivation, suggesting that modification has occurred at the nucleotide binding domain of the active site. Sulfhydryl modification is indicated by partial reversibility of inactivation as effected by exogenous thiols. Tryptic mapping by reverse-phase chromatography of [14C]carboxymethylated enzyme, subsequent to its reaction with either FNPS or DFNB, demonstrates modification of Cys16 and Cys55 by both reagents, and formation of only one major chromophoric peptide in each case. On the basis of the sequence analysis of the purified chromophoric peptides, Cys16 and Cys55 are cross-linked by both FNPS and DFNB. Thus, the intrasubunit distance between the beta-sulfhydryls of Cys16 and Cys55 is dynamic rather than static. Diminished conformational flexibility upon oxidation of the regulatory sulfhydryls to a disulfide may be partially responsible for the concomitant loss of enzymatic activity.

AN - 73346466; 1279401 AB - Limited comparative data in mice indicate that chemical mutagens that induce dominant lethal mutations in males are not necessarily effective in females, but those which are effective in females are generally equally or more effective in males. Recently, however, a few chemicals have been identified that are female-specific with respect to induction of dominant lethal mutations. The antitumor antibiotic adriamycin is among them. Another antitumor antibiotic, bleomycin was examined for its ability to induce dominant lethal mutations in the reproductive cells of male and female mice. No dominant lethal or cytotoxic effects were observed in males treated with bleomycin, even at a maximum tolerated dose. In females, on the other hand, a dose nearly 1/4 of that used in males induced not only a high level of dominant lethal mutations but also killed oocytes in certain stages of follicular development. The effectiveness of bleomycin in inducing dominant lethal mutations in mouse oocytes makes it a valuable tool for investigating whether gonadal transport, inherent differences in the configuration of chromatin in the germ cells of the two sexes or other factors are responsible for the differential susceptibility to bleomycin, which implies potential gender-specific genetic risk in cancer chemotherapy.

AN - 73324038; 1279398 AB - The inducibility of heritable mutations in female mammals has been measured in the mouse specific-locus test (SLT). For radiation-induced mutations, a large body of data has been accumulated that includes information about biological and physical factors that influence mutation yields. However, relatively few SLT studies in females have been conducted with chemicals to date. A single estimate of the spontaneous mutation rate in oocytes, 6/536,207, has been derived as the most appropriate one to subtract from experimental rates. This rate is highly significantly below the spontaneous mutation rate in males. Mutations recovered from females mutagenized at any time after about the 12th day post-conception are induced in non-dividing cells. In adult females, most oocytes are arrested in small follicles; maturation from this stage to ovulation takes several weeks. High-dose-rate radiations are more mutagenic in mature and maturing oocytes than in spermatogonia of the male; on the other hand, no clearly induced mutations have been recovered from irradiated arrested oocytes. Efficient repair processes have been invoked to explain the latter finding as well as the upward-curving dose-effect relation for acute irradiation, and the fact that dose protraction drastically reduces mutation yield from mature and maturing oocytes. The dose-protraction effect is much greater than that found in spermatogonia. Radiation-induced mutation rates in embryonic, fetal, and newborn females are overall lower than those in the mature and maturing oocytes of adults. A dose-protraction effect has also been demonstrated at an early developmental stage when the nuclear morphology of mouse oocytes most resembles that of the human. Of only 5 chemicals so far explored for their effect in oocytes, 2 (ethylnitrosourea, ENU, and triethylenemelamine, TEM), and possibly a third (procarbazine hydrochloride, PRC), are mutagenic--with at least one of these (ENU) mutagenic in arrested as well as maturing oocytes. However, the mutation rate is, in each case, lower than for treated male germ cells. By contrast, ENU-induced mutation yield for the maternal genome of the zygote is an order of magnitude higher than that for the zygote's paternal genome or for spermatogonia. A high proportion of mutants derived from chemical treatment of oocytes (including the oocyte genome in zygotes) are mosaics, probably owing to lesions affecting only 1 strand of the DNA. A characteristic of specific-locus mutations induced in oocytes is that they include a considerably higher percentage of large (multi-locus) lesions (LLs) than do mutations induced in spermatogonia.(ABSTRACT TRUNCATED AT 250 WORDS) JF - Mutation research AU - Russell, L B AU - Russell, W L AD - Biology Division, Oak Ridge National Laboratory, TN 37831-8077.

The conditions of these hydrothermal experiments are: T 300- 600 degrees C, P 1 kbar (0.25 kbar at 300 degrees C; and 0.55, 1 and 2 kbar at 500 degrees C only), m NaCl 0, 0.1, 0.3, 1 and 4; W/S mass (moles) ratio approx 4, run time 211-1956 hr. There is a pronounced increase in F-values with increasing T, salinity, P (500 degrees C example only) and degree of grain rounding and regrowth. The rate of change in F is initially steep but tends to flatten out with increasing NaCl at approx > 1 m. This greater degree of crystallization is probably related to the enhanced solubility of calcite in the presence of NaCl (sub (aq)) . Data of 500 degrees C exhibit a trend of increasing F with increasing P. Rate constants (log r (sub f) in mol. m (super -2) s (super -1) O) calculated from these data range from a maximum value of -6.75 at 600 degrees C, 1 kbar, 4 m NaCl to a minimum rate of -9.46 at 300 degrees C, 0.25 kbar, 0 m NaCl. Activation energies were calculated for each NaCl concentration at 1 kbar, and vary as 15, 16, 19, 20 and 19 kcal/mol. for 0, 0.1, 0.3 1 and 4 m NaCl respectively. Volumes of activation estimated from the 500 degrees C P data range from -40 to -9 cm (super 3) /mol. for 0 and 4 m NaCl, respectively. These data suggest that solvation of ions in solution during the activation step is the dominant process influenced by P. Model calculations indicate that isotopic equilibration times are very rapid, on the order of 10's to 100's of yr at high T (> 500 degrees C), high salinity (> 1 m) and high P (> 1 kbar), depending on the W/S ratio and intial grain size.

The results were modeled as Ge/Si "isotope" fractionation. During exponential growth, diatoms take up and incorporate Ge/Si from solution without major discrimination against Ge. During stationary phase growth near silica limitation, the Antarctic species (T. antarctica) discriminates slightly against Ge but integrated (Ge/Si) (sub opal) produced over the latter portion of the growth cycle is indistinguishable from the initial solution ratio. These results confirm experiments using radioactive (super 68) Ge that showed absence of fractionation during diatom silica uptake (Azam and Volcani, 1981), in contrast to two-box ocean models that invoke 50% Ge discrimination by diatoms to explain the observed "excess" surface ocean germanium concentration (Murnane and Stallard, 1988; Froelich et al., 1989) and late Pleistocene ocean sediment (Ge/Si) (sub opal) records (Mortlock et al., 1991). Runs of a 10-box ocean Ge and Si model (PANDORA) with 50% discrimination reproduce the excess surface ocean Ge but introduces curvature into the deep ocean Ge versus Si relationship that is not observed in the oceans. Thus 50% fractionation is not supported by either cultures or models. If diatoms do not fractionate Ge/Si, then late Pleistocene (Ge/Si) (sub opal) variations in piston cores are caused not by changes in local biosiliceous production and silica utilization (Mortlock et al, 1991) but rather by whole ocean changes in (Ge/Si) (sub seawater) . The marine (Ge/Si) (sub opal) record of the last 450 kyr can be modeled as transient oceanic responses to instantaneous continental climate transitions consistent with the chemical weathering model of Murnane and Stallard (1990). Glacial periods are characterized by lower continental weathering intensity, lower (Ge/Si) (sub riv) , and two fold higher dissolved silica river fluxes. Marine (Ge/Si) (sub opal) records thus contain a history of ocean silica chemistry that reflect rapid global changes in continental weathering. Copyright 1992 by the American Geophysical Union.

AN - 73442028; 1486858 AB - The vesicant agents of the unitary chemical munitions stockpile include various formulations of sulfur mustard [bis-(2-chloroethyl) sulfide; agents H, HD, and HT] and small quantities of the organic arsenical Lewisite [dichloro(2-chlorovinyl) arsine; agent L]. These agents can be dispersed in liquid, aerosol, or vapor form and are capable of producing severe chemical burns upon direct contact with tissue. Moist tissues such as the eyes, respiratory tract, and axillary areas are particularly affected. Available data summarizing acute dose response in humans and laboratory animals are summarized. Vesicant agents are also capable of generating delayed effects such as chronic bronchitis, carcinogenesis, or keratitis/keratopathy of the eye under appropriate conditions of exposure and dose. These effects may not become manifest until years following exposure. Risk analysis derived from carcinogenesis data indicates that sulfur mustard possesses a carcinogenic potency similar to that of benzo[a]pyrene. Because mustard agents are alkylating compounds, they destroy individual cells by reaction with cellular proteins, enzymes, RNA, and DNA. Once begun, tissue reaction is irreversible. Mustard agents are mutagenic; data for cellular and laboratory animal assays are presented. Reproductive effects have not been demonstrated in the offspring of laboratory rats. Acute Lewisite exposure has been implicated in cases of Bowen's disease, an intraepidermal squamous cell carcinoma. Lewisite is not known to generate reproductive or teratogenic effects.

AN - 73277435; 1423866 AB - N-Alkylpurines induced in DNA by simple monofunctional alkylating agents are known to be cytotoxic and possibly indirectly mutagenic. These adducts are removed by the ubiquitous N-methylpurine-DNA glycosylase (MPG) in a multistep repair pathway. Chinese hamster ovary (CHO) cell clones expressing 2- to 16-fold enhanced levels of MPG activity were isolated from cells stably transfected with human MPG cDNA expression plasmids. The in vivo removal of 3-methyladenine and 7-methylguanine from some of these lines was analyzed and was observed to reflect their MPG levels. These cell lines did not develop increased resistance, as compared to the control, in regards to cytotoxic, mutagenic and sister chromatid exchange inducing effects of the alkylating agents that induce 3-alkyladenine and 7-alkylguanine as the major alkyl adducts in DNA. These results suggest that the MPG activity is not limiting in the multi-step repair pathway of N-alkylpurines in CHO cells.

AN - 73224257; 1399637 AB - In this study, the radiation doses to occupants of two reinforced concrete buildings at Nagasaki, who survived the immediate effects of the nuclear weapon detonation, are determined using state-of-the-art radiation transport techniques. The radiation doses at all locations in the buildings are calculated using the Three-Dimensional Oak Ridge Discrete Ordinates Radiation Transport Code which was constructed especially for this task. This code represents a new and unique capability that has been previously reported. This study resulted in case-by-case lists of doses to occupants and an uncertainty analysis. These data have been used in a companion study as the basis for determining a new value of the dose producing a 50% risk of fatality.

AN - 73285301; 1427042 AB - Oxygen association-dissociation and hemoglobin stability analysis were performed on mouse hemoglobins with amino acid substitutions in an alpha-globin (alpha 89, His to Leu) and a beta-globin (beta 59, Lys to Ile). The variant alpha-globin, designated chain 5m in the Hbag2 haplotype, had an high oxygen affinity and was stable. The variant beta-globin, (beta s2) of the Hbbs2 haplotype, also had an elevated oxygen affinity and in addition was moderately unstable in 19% isopropanol. Hemoglobins from the expected nine (Hbag2/Hbag2;Hbbs/Hbbs x Hbaa/Hbaa;Hbbs2/Hbbs2) F2 genotypes can be grouped into five classes of P50 values characterized by strict additivity and dependency on mutant globin gene dosage; physiologically, both globin variants gave indistinguishable effects on oxygen affinity. The hemoglobin of normal mice (Hbaa/Hbaa;Hbbs/Hbbs) had a P50 = 40 mm Hg and the hemoglobin of Hbag2/Hbag2;Hbbs2/Hbbs2 F2 mice had a P50 = 25 mm Hg (human P50 = 26 mm Hg). Peripheral blood from Hbag2/Hbag2;Hbbs/Hbbs, Hbaa/Hbaa;Hbbs2/Hbbs2 and Hbag2/Hbag2;Hbbs2/Hbbs2 mice exhibited normal hematological values except for a slightly higher hematocrit for Hbag2/Hbag2;Hbbs/Hbbs and Hbag2/Hbag2;Hbbs2/Hbbs2 mice, slightly elevated red cell counts for mice of the three mutant genotypes, and significantly lower values for the mean corpuscular volume and mean corpuscular hemoglobin for Hbag2/Hbag2;Hbbs2/Hbbs2 mice.

AN - 73265365; 1412508 AB - The metabolic interactions of benzene and gasoline vapor were investigated in male Fischer-344 rats. A closed chamber gas-uptake exposure system was used to obtain inhalation uptake curves for benzene alone and benzene in the presence of gasoline vapor. Exposure to benzene as a component of gasoline vapor resulted in a decrease of benzene metabolism. A physiologically based pharmacokinetic model of benzene metabolism was used to quantitatively determine the extent of the inhibitory effect of gasoline vapor on benzene metabolism. This observed inhibitory effect cannot be accounted for by the presence of toluene in gasoline vapor.

AN - 73236719; 1399773 AB - A biomonitoring protocol, using blood cholinesterase (ChE) activity in livestock as a monitor of potential organophosphate nerve agent exposure during the planned destruction of US unitary chemical warfare agent stockpiles, is described. The experimental design included analysis of blood ChE activity in individual healthy sheep, horses, and dairy and beef cattle during a 10- to 12-month period. Castrated and sexually intact males, pregnant and lactating females, and adult and immature animals were examined through at least one reproductive cycle. The same animals were used throughout the period of observation and were not exposed to ChE-inhibiting organophosphate or carbamate compounds. A framework for an effective biomonitoring protocol within a monitoring area includes establishing individual baseline blood ChE activity for a sentinel group of 6 animals on the bases of blood samples collected over a 6-month period, monthly collection of blood samples for ChE-activity determination during monitoring, and selection of adult animals as sentinels. Exposure to ChE-inhibiting compounds would be suspected when all blood ChE activity of all animals within the sentinel group are decreased greater than 20% from their own baseline value. Sentinel species selection is primarily a logistical and operational concern; however, sheep appear to be the species of choice because within-individual baseline ChE activity and among age and gender group ChE activity in sheep had the least variability, compared with data from other species. This protocol provides an effective and efficient means for detecting abnormal depressions in blood ChE activity in livestock and can serve as a valuable indicator of the extent of actual plume movement and/or deposition in the event of organophosphate nerve agent release.

The ISV process transforms permeable, easily leached, contaminated soils into low-permeability, leach-resistant vitreous and crystalline materials via in situ joule (resistance) heating [Buelt et al., 1987]. Melting is induced by applying electrical power to the ground through four graphite electrodes in a square configuration inserted vertically into the upper portion of the soil to be melted. Melting proceeds downward, producing a roughly hemispheric body that cools to a glassy to partially crystalline material. A hood is placed over the melt to collect gases and particulates released from the melt.

AN - 73146779; 1509497 AB - Duvernoy's gland secretions (100 micrograms/ml) from the eastern hognose snake, Heterodon platirhinos, induced a neuromuscular blockade in the isolated frog sciatic nerve-gastrocnemius muscle preparation and effectively antagonized acetylcholine and histamine responses of the rat duodenum preparation. The Duvernoy's secretions (100 micrograms/ml) produced a reversible, excitatory effect in the guinea-pig ileum in vitro. Mice administered the secretions (100 mg/kg, i.p.) exhibited minor, transient signs of toxicity. These preliminary observations provide evidence for toxicity of H. platirhinos Duvernoy's gland secretions but do not warrant categorizing the potential toxicity of this species with that of proteroglyphous, solenoglyphous, or the more venomous opisthoglyphous species.

AN - 73065408; 1378547 AB - Melphalan (MLP), a bifunctional alkylating agent structurally related to the highly mutagenic chemical chlorambucil (CHL), was found to induce high frequencies of specific-locus mutations in postspermatogonial germ cells of the mouse, and to be one of only a few chemicals that is also mutagenic in spermatogonial stem cells. Productivity patterns following MLP exposures resembled those that had been found for CHL. Mutation rates in successive male germ-cell stages were measured at three MLP-exposure levels in a total of 95,375 offspring. While the induced (experimental minus historical-control) mutation rate is relatively low in stem-cell spermatogonia (1.2 x 10(-5) per locus at a weighted-mean exposure of 7.3 mg/kg), it is about 5 times higher in poststem-cell stages overall, and peaks at 26.7 x 10(-5) per locus in early spermatids at a weighted-mean exposure of only 5.7 mg/kg. This "type-2 pattern" of mutation yield (Russell et al., 1990), i.e., peak sensitivity in early spermatids, has heretofore been found for only one other chemical, CHL. Mutation-rate data earlier reported for CHL (Russell et al., 1989) were augmented in the present study for comparison with MLP-induced rates. Because of the greater toxicity of MLP, average exposures used for this chemical were only about one-half of those for CHL. When MLP and CHL mutation rates are extrapolated to equimolar doses, they appear very similar for poststem-cell stages overall. However, in the case of CHL, a somewhat higher proportion of the mutations is induced in early spermatids than in the case of MLP.

AN - 73062453; 1352884 AB - Specific-locus experiments have previously shown melphalan to be mutagenic in all male germ-cell stages tested and particularly so in early spermatids. All but 2 of 24 specific-locus mutations recovered were tested genetically, cytogenetically, and/or molecularly. At least 12 of 15 tested mutations recovered from postspermatogonial stages but only 1 of 7 mutations recovered from stem-cell or differentiating spermatogonia gave evidence of being deletions or other rearrangements. Melphalan-induced mutations, thus, confirm the pattern of dependence of mutation structure on germ-cell stage that had been shown earlier for other chemicals. Results of the present investigation illustrate the capabilities of combined genetic, cytogenetic, and molecular analyses for characterizing the nature of specific-locus mutations. Fine-structure molecular mapping of long regions surrounding specific loci has been greatly facilitated by the availability of genetic reagents (particularly, deletion complexes) generated in specific-locus experiments over the course of decades. Reciprocally, this mapping permits increasingly detailed characterization of the nature of lesions induced by mutagenic exposures of germ cells, adding great powers for qualitative analysis of mutations to the specific-locus test. Cytogenetic and genetic investigations also provide evidence on lesion type, especially for loci at which mutations cannot yet be analyzed molecularly. Melphalan, like chlorambucil, can generate many mutations, a high proportion of which are deletions and other rearrangements, making this chemical valuable for generating mutations (at any locus) amenable to molecular access.

Methods for adduct detection are also reviewed and approaches to sensitivity and specificity are identified. The selection of these 12 chemicals from the Environmental Protection Agency list of genotoxic chemicals was based on the availability of information and on the availability of populations potentially suitable for molecular epidemiological study. The 12 chemicals include ethylene oxide, styrene, vinyl chloride, epichlorohydrin, propylene oxide, 4,4'-methylenebis-2-chloroaniline, benzidine, benzidine dyes (Direct Blue 6, Direct Black 38 and Direct Brown 95), acrylonitrile and benzyl chloride. While some of these chemicals (styrene and benzyl chloride, possibly Direct Blue 6) give rise to unique DNA adducts, others do not. Potentially confounding factors include mixed exposures in the work place, as well the formation of common DNA adducts. Additional research needs are identified.

AN - 72999496; 1376237 AB - In the event of an unplanned release of a chemical warfare agent during any stage of the Chemical Stockpile Disposal Program, the potential exists for off-post contamination of drinking water, forage crops, grains, garden produce, and livestock. The more persistent agents, such as the organophosphate nerve agent VX, pose the greatest human health concern for reentry. A relative potency approach comparing the toxicity of VX to organophosphate insecticide analogues is developed and used to estimate allowable residues for VX in agricultural products and reentry intervals for public access to contaminated areas. Analysis of mammalian LD50 data by all exposure routes indicates that VX is 10(3) to 10(4) times more toxic than most commercially available organophosphate insecticides. Thus, allowable residues of VX could be considered at concentration levels 10(3) to 10(4) lower than those established for certain insecticides by the U.S. EPA. Evaluation of reentry intervals developed for these organophosphate analogues indicate that, if environmental monitoring cannot reliably demonstrate acceptable levels of VX, restricted access to suspect or contaminated areas may be on the order of weeks to months following agent release. Planning for relocation, mass care centers, and quarantine should take this time period into account.

AN - 72877674; 1559814 AB - An extensive network of gummed paper collectors was used during the 1950s for routine monitoring of radioactive fallout from weapons testing. The experiments reported in this paper were designed to examine the collection efficiency of gummed paper for wet deposition of several types of soluble and insoluble radioactive contaminants under conditions similar to those found during natural rainstorms. The collection efficiencies for each substance were determined over a range of rainfall amounts and at two separate rainfall intensities. The collection efficiency of the gummed paper is highest for large insoluble particles and lowest for soluble ionic substances. The values for 7Be and 131I ranged from about 0.30 (30%) at 2.5 mm of rain to 0.04-0.06 (4%-6%) at 20 mm of rain. These values were negatively correlated with the amount of rain and were unaffected by rain intensity. This suggests that the collection efficiency of either ion is simply a matter of rapid saturation and runoff. Neither rain amount nor rain intensity has much effect on the collection efficiency of large insoluble particles. These particles seem to settle readily onto the surface of the gummed paper from which they are not easily removed by additional rain. Analysis of the collection efficiencies of the gummed paper included the activity of both the gummed paper and the standing water on the paper. A large portion of the activity for the ionic substances was found in the standing water. There was less activity by insoluble particles in standing water. This indicates that for estimates of deposition of soluble substances, considerable bias could be introduced into the results if the standing water is discarded prior to analysis.

AN - 72901965; 1569095 AB - Crystallographic studies of ribulose-1,5-bisphosphate carboxylase/oxygenase from Rhodospirillum rubrum suggest that active-site Asn111 interacts with Mg2+ and/or substrate (Lundqvist, T., and Schneider, G. (1991) J. Biol. Chem. 266, 12604-12611). To examine possible catalytic roles of Asn111, we have used site-directed mutagenesis to replace it with a glutaminyl, aspartyl, seryl, or lysyl residue. Although the mutant proteins are devoid of detectable carboxylase activity, their ability to form a quaternary complex comprised of CO2, Mg2+, and a reaction-intermediate analogue is indicative of competence in activation chemistry and substrate binding. The mutant proteins retain enolization activity, as measured by exchange of the C3 proton of ribulose bisphosphate with solvent, thereby demonstrating a preferential role of Asn111 in some later step of overall catalysis. The active sites of this homodimeric enzyme are formed by interactive domains from adjacent subunits (Larimer, F. W., Lee, E. H., Mural, R. J., Soper, T. S., and Hartman, F. C. (1987) J. Biol. Chem. 262, 15327-15329). Crystallography assigns Asn111 to the amino-terminal domain of the active site (Knight, S., Anderson, I., and Brändén, C.-I. (1990) J. Mol. Biol. 215, 113-160). The observed formation of enzymatically active heterodimers by the in vivo hybridization of an inactive position-111 mutant with inactive carboxyl-terminal domain mutants is consistent with this assignment.

AN - 72864774; 1551863 AB - The CO2/O2 specificity factor of ribulose-bisphosphate carboxylase/oxygenase partially determines the efficiency of photosynthetic carbon assimilation. Heretofore, engineered alterations of the enzyme have only decreased the selectivity for CO2 utilization. We show that alanyl replacement of active-site Ser-368 of the Rhodospirillum rubrum carboxylase enhances the carboxylation selectivity approximately 1.6-fold over the wild-type level. This enhancement reflects a greater relative decline in oxygenase efficiency than in carboxylase efficiency. In contrast to wild-type enzyme, the carboxylase activity of the Ser-368 mutant protein is not perceptibly inhibited by O2, perhaps indicative of a change in rate-limiting steps in the overall reaction pathway.

AN - 73176302; 1515773 AB - An increasingly important topic in risk assessment is the estimation of human exposure to environmental pollutants through pathways other than inhalation. The Environmental Protection Agency (EPA) has recently developed a computerized methodology (EPA, 1990) to estimate indirect exposure to toxic pollutants from Municipal Waste Combuster emissions. This methodology estimates health risks from exposure to toxic pollutants from the terrestrial food chain (TFC), soil ingestion, drinking water ingestion, fish ingestion, and dermal absorption via soil and water. Of these, one of the most difficult to estimate is exposure through the food chain. This paper estimates the accuracy of the EPA methodology for estimating food chain contamination. To our knowledge, no data exist on measured concentrations of pollutants in food grown around Municipal Waste Incinerators, and few field-scale studies have been performed on the uptake of pollutants in the food chain. Therefore, to evaluate the EPA methodology, we compare actual measurements of background contaminant levels in food with estimates made using EPA's computerized methodology. Background levels of contaminants in air, water, and soil were used as input to the EPA food chain model to predict background levels of contaminants in food. These predicted values were then compared with the measured background contaminant levels. Comparisons were performed for dioxin, pentachlorophenol, polychlorinated biphenyls, benzene, benzo(a)pyrene, mercury, and lead.

The Na (super *) substitution has a strong effect on 1/2 c. sin BETA and V and only a small effect on a and b; Fm substitution in muscovite causes the a and b dimensions to increase. However, the associated increase of a and b dimensions of the octahedral sheet necessitate rotation in the associated tetrahedral sheet such that the 1/2 c.sin beta dimension decreases concomitantly. The results may provide some insights on the effects of P on the solvus limbs, and a possible explanation of the low Na contents typical of phengitic muscovites, and the low phengite contents typical of paragonites.

AN - 72796866; 1735643 AB - Analysis of primary treatment sludge from a municipal wastewater treatment plant revealed elevated 137Cs concentrations in one sample. This elevated activity was associated with a radioactive particle that, when isolated and quantified, was found to contain 1.82 kBq of 137Cs. Additional analysis indicated an absence of alpha activity, and energetic beta radiation, if present, was less than the 137Cs activity. The particle was approximately 50 microns in diameter, appeared not to be an aggregate, and was nonmetallic.

AN - 72792745; 1733935 AB - In a preliminary study we demonstrated that the formation of the epidermal growth factor (EGF) receptor-ligand complex requires the participation of the highly conserved arginine 41 side chain of the growth factor peptide (Engler, D.A., Montelione, G.T., and Niyogi, S.K. (1990) FEBS Lett. 271, 47-50). In an attempt to gain further insight into the nature of this interaction(s), we used both site-directed mutagenesis and chemical modification reagents to produce human EGF (hEGF) analogues with altered chemical properties of the residue 41 side chain. Eight mutant analogues of hEGF were generated, substituting arginine 41 with lysine, glutamine, isoleucine, tyrosine, glycine, alanine, aspartate, or glutamate. Although each of the mutant analogues was able to displace wild-type hEGF fully in receptor competition binding assays, affinity of the receptor for the mutants was substantially reduced, varying from 0.4 to less than 0.01% of that observed for wild-type growth factor. At sufficiently high concentrations these mutants were able to stimulate DNA synthesis in mouse keratinocytes. Substitution of lysine for arginine 41 reduced the receptor affinity 250-fold from that observed for wild type, despite retention of the positive electrostatic charge. The lysine substitution leaves a reactive amine at position 41 and made it possible, using amine-specific chemical modification reagents, to produce selected arginine homologues that were tested for their effects on receptor binding, receptor tyrosine kinase activation, and stimulation of DNA synthesis in mouse keratinocytes. The reaction of lysine 41 with methyl acetimidate resulted in a lysineacetamidine product which only partially restored activity of the lysine hEGF mutant. However, reaction with O-methylisourea resulted in generation of an arginine 41 homologue (homoarginine) which restored full activity. The results indicate that the chemical properties inherent in the guanidinium group of the arginine 41 side chain of hEGF are responsible for optimal receptor-ligand association.

AN - 72988966; 1601219 AB - Acrylamide is used extensively in sewage and wastewater treatment plants, in the paper and pulp industry, in treatment of potable water, and in research laboratories for chromatography, electrophoresis, and electron microscopy. Dermal contact is a major route of human exposure. It has been shown that acrylamide is highly effective in breaking chromosomes of germ cells of male mice and rats when administered intraperitoneally or orally, resulting both in the early death of conceptuses and in the transmission of reciprocal translocations to live-born progeny. It is now reported that acrylamide is absorbed through the skin of male mice, reaches the germ cells, and induces chromosomal damage.

AN - 75533443; 11537037 AB - While Q is specified as a function of linear energy transfer (LET) in practice the Q for neutrons has been selected by a judgment decision based on the relative biological effectiveness (RBE) to induce stochastic effects. There are no RBE values for tumor induction by heavy ions or protons in humans. Thus, selection of Q values has been based either on LET (or lineal energy) or RBEs from animal experiments. Estimates of Q for heavy ions in low earth orbit (LEO) range from about 5 to 14. The average Q value of all radiation in LEO has been estimated to be about 1.3. There is a lack of experimental data for RBEs for heavy ions but RBE increases as a function of LET. In the case of the Harderian gland the RBE reaches a maximum of 25-30 between about 100-200 keV/micrometer but does not appear to decrease at higher LETs. The International Commission of Radiological Protection have proposed the use of radiation weighting factors in lieu of quality factors. The weighting factors will range from 1 to 20.

However, in the past there has been too little attention paid to the historical aspect of these data; they can be properly utilized only when their historical contexts are fully appreciated. For this reason, the global change researcher could fruitfully apply some of the methodologies of the historian to the analysis of historical remote sensing data. However, there can be no true understanding of historical context without some knowledge of the different concepts of time that underlie the various approaches to historical events. It is also important to be aware of the temporal models that can be employed in the analysis of historical data. This paper offers ideas for the applications of historical methodology to remote sensing data analysis, provides an understanding of the development of various time concepts that may apply to these data, and delineates several temporal models which can give a framework to historical analysis.

USRADS uses ultrasonics to provide real-time surveyor positioning and radio links to transmit the surveyor data to an on-site computer for storage and real-time display. USRADS uses a standard 386 computer for data collection and includes real-time color display of the findings. It also includes numerous analysis and display formats for on-site, as well as utilities to facilitate post-process analysis of the findings. The objective of one project was to locate several suspect waste disposal trenches and to map their boundaries. The second was to locate and map the presence of subsurface unexploded ordinance (UXO) at a suspect artillery impact area. A Geonics EM31 terrain conductivity meter interfaced to USRADS was used to map the suspect trenches. A Schonstedt GA-52C magnetometer interfaced to USRADS was used to map the subsurface UXO. Correlation of findings to known site features and additional knowledge about the sites indicates that these efforts did locate and map the geophysical features including the suspect waste trenches and the subsurface UXO.

The method is based largely on phase-equilibrium and calorimetric data that are either currently available or readily obtainable. P-V-T data are not required. Good agreement is found with results from other methods.

Great blue herons, that occupy a colony located on the Oak Ridge Reservation and feed along the Clinch River and tributaries, have been identified as an endpoint species for assessing risks to piscivorous wildlife. Concentrations of mercury and PCB determined in eggs and chicks, reproductive success and biochemical biomarkers in chick tissues are being evaluated. Results are being used to (a) validate a food web model of Hg and PCB movement from contaminated media to herons, (b) determine whether reproductive effects are occurring in the colony, (c) determine what contaminant concentrations are associated with effects, (d) develop remedial action goals, and (e) assess the efficacy of remedial actions.

Cylindrical concrete enclosures (2.5 m diameter) placed in a stream channel containing mercury-contaminated (100 mu g/g) sediments were used to directly measure the accumulation of mercury by fish exposed to sediment-associated mercury in the presence and absence of mercury in the influent water. Fish were also exposed to the two water sources in streamside enclosures without sediments. Measurements were made of mercury concentrations and speciation in water, sediments, fish, and their food over a 15-week period. Aqueous phase concentrations of methylmercury were low (0.2-0.4 ng L super(-1)), indicating low rates of production of this substance, and were relatively similar among treatments. Fish in the instream enclosures receiving mercury- contaminated water (1.1 mu g L super(-1) total mercury) accumulated mercury at a low rate (4x 104 mu g g super(-1) d super(-1)). This rate was six times greater than that in instream enclosures not receiving aqueous mercury. Mercury accumulation in fish was most rapid in the treatment receiving contaminated water without sediments, but most of the mercury that accumulated was inorganic mercury, not methylmercury. Mercury and methylmercury in food materials did not explain the differences in mercury accumulation in fish among treatments.

Embryos of the Japanese medaka (Oryzias latipes) were exposed to sterile-filtered surface water from three creeks whose watersheds include three large DOE facilities, and from the Clinch River (CR) which receives drainage from all three creeks. The primary contaminants include mercury and radionuclides but organics such as PCBs, and other metals may also be present. Water from White Oak Creek (wac), draining the Oak Ridge National Laboratory, and East Fork Poplar Creek (EFPC), draining that Y-12 Plant, were highly toxic to medaka embryos downstream of the plants. Water from Poplar Creek (PC) was also highly toxic downstream of EFPC, but the K-25 Plant apparently added little additional embryo toxicity. In spite of the adversa effects on medaka embryos of water from WOC, EFPC, and PC, water from the CR had little toxic effect on these embryos. The results of these studies suggest that the medaka embryo-larval test can be a useful tool to examine the developmental toxicity of ambient water sources.

Ecological Risk Assessment (ERA) for these hazardous waste sites must be like conventional predictive risk assessments in their use of a formal risk paradigm including well defined endpoints and incorporation of uncertainty. However, they differ in that sources of contamination, exposure levels, and effects can be measured in the contaminated environment so an epidemiological approach must be applied. The sites are distributed across the reservation in four watersheds. Therefore, a conventional approach of assessing each source independently without consideration of the geographic pattern of sources and resources is unacceptable. A modification of the conventional risk assessment paradigm to incorporate ecological epidemiology will be presented. A hierarchical approach to performing the assessments will also be presented that combines the need to remediate individual sites with the need to minimize risks to larger ecological units. This modified paradigm and hierarchical approach will be illustrated with examples from ongoing assessment activities for the Oak Ridge Reservation.

Histories and other chromatin proteins were dissociated from the DNA and separated by polyacrylamide gel electrophoresis. Both double-and single-strand DNA breaks were determined by agarose gel electrophoresis. Changes in the patterns of expression of chromatin proteins occurred in exposed fish, suggesting that chromosomal proteins can be used as a novel biomarker. Also, patterns of DNA migration in the agarose gels indicated an increase in both double- and single-strand breaks in the exposed fish. Thus, electrophoresis can be an alternative method to detect DNA damage from environmental toxins. These results indicate that fish blood cells could be useful in assessing genotoxicity.

We address this question in an ongoing project employing biomarkers and other biomonitoring techniques to examine the health of fish in a PCB-contaminated reservoir. Largemouth bass (Micropterus salmoides) from the contaminated arm of Hartwell Lake, S.C., average over 20 ppm PCBs in muscle tissue. The Health Assessment Index (HAl), a screening procedure which relies primarily on morphological characteristics such as organ size and appearance, indicates that fish health in the reservoir declines as PCB body burdens increase. Responses of a suite of biochemical, physiological, and reproductive biomarkers of contaminant exposure and effects generally support this assessment. Population characteristics such as mean age (lower in the contaminated arm), instantaneous mortality rate (higher), and survival rate (lower) further suggest that larger fish typically having the highest body burdens of PCBs have experienced the greatest impact from such exposures. Continuing studies should enhance our ability to distinguish the effects of PCBs on the health of affected fish populations.

Residue analyses of animal tissues can show that chemical exposure has occurred, and biochemical, histological, and criteria can be used to further document exposures. Trophic level is an important factor affecting chemical exposure of small mammals in the field; consequently, insectivores are generally excellent sentinels for ambient contamination whereas herbivores are not. A review of published studies indicates that demographic endpoints, such as the distribution and abundance of small mammal species and age/size structure of populations are rarely useful indices for toxicant exposure.

The availability of software for Monte Carlo simulation has made it easy to express model parameters as distributions, to propagate parameter uncertainties through the model and express the output as distributions or percentiles. However, the problems of selecting the input distribution functions and estimating the parameters of those functions present conceptual difficulties. This talk will present a conceptual approach for dealing with this problem and some rules-of-thumb for applying the approach. Examples drawn from environmental risk assessments will be used to illustrate the approach and recommendations. JF - 13th Annual Meeting Society of Environmental Toxicology and Chemistry - Abstracts.

During the manufacturing of TNT and RDX, various nitroaromatic compounds are released into the environment. The primary contaminants include 2,4,6-trinitrotoluene, 2,4- and 2,6-dinitrotoluene, RDX, and associated degradation products. These compounds are released to aquatic systems primarily via wastewater effluents or by leaching from soils. The fate processes affecting the persistence and transformation of these compounds in natural waters are biodegradation and photolysis, both of which occur more rapidly in the presence of an exogenous carbon source. Sediment adsorption is expected to be low; however, once bound by the sediments, release is slow providing a long-term sink. Exposure to these compounds poses a threat to the environment as well as to human health. Human exposure can occur by the consumption of contaminated surface water used as a drinking water source or by the consumption of contaminated aquatic organisms. Water Quality Criteria for the protection of human health and aquatic organisms have been derived to establish cleanup levels for remediation of these compounds in aquatic systems at these Superfund sites.

Fish were collected after 1, 2, 4, 8 and 16 weeks of exposure. The number of DNA strand breaks fluctuated over time, and were more evident from longer exposures. B[a]P DNA and hemoglobin adducts were evident in exposed fish and increased over time. Hematopoesis was affected as evidenced by depression in ALAD activity and increase of zinc protoporphyrins in the blood. Both ATPase and Ache activities were inhibited by exposure. Liver detoxification enzymes were induced by exposure, and activities increased over time. Patterns of biomarkers were similar to those in fish sampled from the site of origin of the contaminated sediment.

It has now been demonstrated that certain plant tissues are also effective for this type of adsorption process. In particular, tomato and tobacco roots harvested from field-grown plants were shown to adsorb Sr from an aqueous solution of SrCl sub(2). Distribution coefficients in excess of 550 were measured and the adsorption isotherms at 25 degree C could be fitted to Langmuir-type expressions. The bioadsorbent could be regenerated and metals recovered by either a reduction in the pH to less than 2.0 or by use of a concentrated chloride salt solution.

Traditionally, the Ogallala aquifer recharged the underlying Cretaceous and Triassic aquifers. Hydrologic, chemical and isotopic evidence suggested that there were independent recharged sources for the Cretaceous aquifers and that there was no present recharge to the Triassic aquifers. In places, these aquifers recharge the overlying Ogallala aquifer. Playa lakes might be the major recharge source of the Ogallala aquifer. There are 41 references.

The stripper comprised a torus filled with packing materials, rotating within a fixed housing, the water admitted at the inner circumference of the torus being driven by centrifugal force through the packing and contacting air admitted under pressure between the outer circumference of the packing and the housing. Alternative packing materials of similar surface area per m3 were used, one a spongy metallic material of nickel and chromium, the other a wire gauze. The rotation speed and the rates of water and air injection were adjusted until the on-line hydrocarbon analyser gave a constant reading for 30 minutes. The hydraulic capacity of the unit, determined by the depth of the packing, was varied in 3 steps and the rotational speed varied until flooding of the packing, arising when the gravitational force on the water exceeded the centrifugal, occurred. The data collected suggested that the Sherwood flooding formula, previously used to determine this limit, had over-estimated the rotational speed at which it occurred and should be modified to take account of the specific surface area of the packing. Some fouling of the packing, identified as iron, was experienced and water treatment for iron removal is recommended as a pre-treatment.

To investigate factors affecting contaminant movement in aquifers, experiments were carried out on the co-transport of an ionic contaminant (cadmium) and 2 non-ionic contaminants (2 polychlorinated biphenyls) with naturally occurring colloidal dissolved organic carbon (DOC) in laboratory columns filled with aquifer material. The mobility of both types of contaminant increased with increase in concentration of DOC. The presence of DOC also affected desorption processes. The increase in contaminant mobility could be explained by incorporating a 3-phase system (2 mobile and 1 stationary) into the convective-dispersion transport equation. The implications for the transport of contaminants in groundwater systems receiving landfill leachate are indicated. There are 34 references.

Conventional risk assessment was supplemented by incorporating epidemiological approaches. Diagrams of conventional risk assessment procedures and of risk characterization in ecological epidemiology are included. The preliminary findings from application of this approach to White Oak creek are outlined. The ecological impacts observed in the creek were caused primarily by point-source discharges associated with plant operations, and surface and subsurface run-off of contaminants from past waste-disposal sites was apparently not causing significant adverse effects on the biota in receiving streams. This contrasted with predictions from conventional laboratory toxicity tests based on concentrations of metals in the stream water; possible reasons for this are indicated.

Mass balance budgets for acid neutralization capacity AN - 13713720; 199203370 AB - Three catchment acidification models were compared by using a combination of input mapping and acid neutralizing capacity (ANC) mass balance budgets to ensure comparable input variables without the need of calibration. Model inputs related to 2 forested lakes of ANC 0-50 ueq per litre which differed considerably in size, catchment to lake area ratio and soil thickness. The 3 models predicted similar ANC outflow fluxes and comparable responses for different deposition patterns. Terrestrial weathering was a major source of ANC in all cases and cation exchange was responsible for changes as deposition fell. Other processes were more model specific, such as sulphate sorption for MAGIC and in-lake weathering for ETD. The processes responsible for changing ANC were different from those contributing to its absolute value. The work completed a previous Monte Carlo analysis showing the 3 models to be structurally different and that predictions viewed on a relative scale agreed better than absolute scale predictions.

The results, together with selected published data, were modelled by the Pitzer ion interaction treatment, chosen for its ability to describe accurately the excess thermodynamic properties of high ionic strength solutions. A simple equation involving 8 adjustable parameters gave the molal concentration quotient of the reversible reaction between aluminium hydroxide and the hydroxyl ion. From this, the equilibrium constant at infinite dilution and the stoichiometric molal activity coefficient ratio were evaluated at 1 atmosphere over 0-100C and 0-12 molal ionic strength. The ratio was independent of cation solubilities but influenced by the anions. Standard thermodynamic values for the reactions and the aluminate ion at 25C were calculated and found to be consistent with published data. Scrupulous attention to the quality of the starting material was essential to eliminate high energy features and avoid spurious solubility measurements in systems such as that studied where reaction kinetics were sluggish and metastable polymorphs could form.

The accumulation of sediment reduced the depth of water and this, together with nutrient inputs, encouraged development of aquatic plants. During the growing season large amounts of the macrophyte Potamogeton foliosus and of filamentous algae were carried into the creek and the effects of this had been investigated. The amounts of organic carbon deposited from the plants within 1.4 km of the impoundment were at least 2.4 times greater than autochthonous production. Experiments on the feeding preferences of a snail, an amphipod and a microcrustacean showed that all 3 types could differentiate between contaminated and non-contaminated food. Leachates from contaminated plants were toxic to the crustacean (Ceriodaphnia dubia). The implications of the findings for aquatic species in the stream are discussed. There are 38 references.

The initial pH was controlled by the addition of hydrochloric acid. The equilibrium quotient for the reaction of aluminium hydroxide with hydrogen ion was modelled in 2 ways: by an empirical equation including the Debye-Huckel term; and by the Pitzer ion interaction treatment using parameters available in the literature. The latter approach employed 4 independent variables, 3 of which were unaffected by temperature. The calculated equilibrium quotients and thermodynamic values were consistent with the most recently reported measurements but not with older results. This was ascribed to the shortcomings of earlier solubility measurement techniques and incorrect estimates of temperature dependence. Using sodium trifluoromethanesulphonate as the supporting electrolyte, no evidence of complex formation between aluminium and chloride ions was found at 50C and 5 molal ionic strength.

The instrument transmitted information to the surface where it could be examined on a screen or recorded on videotape. The introduction of the instrument caused a massive disturbance of particles which took up to 24 h to revert to concentrations typical of the groundwater flow. Following stabilization, colloid sizes of 0.1-100 um were seen. Pumping effects were investigated. Reliable samples were most likely to be obtained under the following conditions: a delay after the introduction of pumps or other devices; minimal purging; sampling flow rates around 100 mlitre per minutes; and samples should not be filtered. This approach gave samples representative of the groundwater, including its colloidal content and resulted in cost savings.

The theory relevant to the mobilization or erosion of particles attracted to surfaces in saturated porous media is discussed, based on the balance of forces at the surface and generally considering only London-van der Waals attractive forces, electrical double-layer attractive or repulsive forces, and sometimes near-range Born repulsive forces. Results are presented from laboratory experiments with sand columns to study mobilization under changing chemical conditions. Mobilization of deposited colloidal particles from surfaces in porous media was negligible or very slow unless there was some physical or chemical alteration of the system, such as a reduction in the ionic strength of the solution. There was also some evidence that mobilization was affected by flow rate, and further studies were required on this aspect.

The production of epilithic bacteria and bacteria on decomposing leaves, leaf decomposition rates, density and generic richness of scraper/grazer macroinvertebrates (particularly Ephemeroptera) and fish abundance and survival all decreased with increasing streamwater acidity, but total macroinvertebrate density and the densities of macroinvertebrates and bacteria associated with stream sediments showed no relationship to streamwater acidity. Regional differences in the relationship between some biological characteristics and streamwater acidity could be due to the toxic effects of monomeric aluminium in the Adirondacks. The results for the Southern Blue Ridge sites suggested that the primary long-term negative effects of stream acidification could be on macroinvertebrate community composition and bacterial metabolism rather than on total density and biomass.

Measurements of biomarker responses in organisms from sites of suspected pollution had been used to identify and assess contaminant-associated risks to ecological resources. Biomarkers could provide not only evidence of exposure to a broad spectrum of anthropogenic chemicals, but also a temporally integrated measure of bioavailable contaminant levels. Several biomarkers were evaluated over time to determine the extent and possible consequences of a problem. Correlations between biomarker response and adverse ecological effects were determined from estimates of animal health and population structure.

Over a 1 year period on Walker Branch watershed the mean delta nitrogen-15 value (per mil) for ammonium (minus 3.4) was significantly less than that for nitrate (plus 2.3). The same relative pattern was observed in cloud water from Whitetop mountain with delta nitrogen-15 values (per mil) of minus 5.5 and plus 1.4, respectively, for ammonium and nitrate. The results were consistent with nitrogen-15 arising through the washout of atmospheric ammonia. Nitrate origins were not clearly established. Thus the potential importance of ammoniacal nitrogen inputs to forest nitrogen cycling was indicated.

The results were applied to a biological response model to ascertain the impact of changes on brook trout, which were widely found in waters susceptible to acid deposition. Projections were made for scenarios where the decline of sulphate deposition was accelerated by new legislation and where it occurred only for the technological and commercial reasons. In the latter case, the number of Mid-Atlantic Highland lakes with ANC below 0 ueq per litre would increase before improving by 2030. In the worst cases, 21 per cent of brook trout habitats could be lost. With legislative controls, the improvements would occur 20-30 years earlier. Uncertainties in predictions were investigated with field observations, paleolimnological findings and calibrations. Model projections were likely to be in the upper range of changes to be expected.

The breakthrough of DOC from columns was dependent on complex adsorption reactions between DOC and the aquifer material. The occurrence of preferential adsorption of DOC subcomponents during transport was also evaluated.

The contaminated stream was a third- to fifth-order stream receiving point-source discharges of various contaminants near its headwaters. High levels of detoxification enzymes that provided evidence of direct toxicant exposure were associated with low lipid levels, histopathological damage and reduced growth of fish at the upper 3 contaminated sites. Decreased fecundity was also shown by these fish. The integrated approach for investigating the relationship between contaminant exposure, physiological effects and responses at the population levels are proposed as a model for designing biomonitoring studies and for stimulating further research.

AN - 13705338; 199300022 AB - Vapour extraction was an in-situ procedure for removing volatile organic compounds from the unsaturated (vadose) zone of the soil. It involved one or more air-injection wells and 1 or more extraction wells for collecting the exhaust air containing the contaminants and transporting it to emission control equipment for treatment before release to the environment. Studies at 13 sites showed apparent removal efficiencies of 85-100 per cent. Factors contributing to the greater efficiency of vapour extraction as compared with groundwater pumping are considered. However, further studies had indicated that vapour extraction systems would not be effective for removing contaminants trapped in the interior of the soil matrix, and could not therefore be relied on to return long-contaminated soils to their pristine condition.

Simulated rain containing both soluble and insoluble radionuclides was applied to pasture-type vegetation in conditions similar to those found during convective storms. The characteristics of the simulated rain, such as droplet size, and the fairly high intensity of application were also comparable with conditions found with irrigation systems. The results were therefore potentially useful in evaluating possible contamination of crops by irrigation using contaminated groundwater.

Visceral-somatic index was significantly elevated in BKME-exposed fish, while liver-somatic index was significantly reduced. Several reproductive parameters were measured, and there were significantly more atretic vitellogenic oocytes in females from the contaminated stream, possibly due to lower serum levels of oestradiol. The L. auritus population structure in Pigeon river was dominated by larger and older individuals relative to the reference population. BKME could affect the fish populations studied primarily through reproductive dysfunction and recruitment. Species richness and composition were greatly reduced in the contaminated river, and an imbalance in trophic structure was evident. There are 54 references.

The weathering of parent dolomite in the soil was the dominant source of inorganic phosphorus. The riparian zone was a potential source of ammonium and phosphorus when dissolved oxygen concentrations were high. Between late autumn and spring, high rates of in-stream immobilization of inorganic nitrogen and phosphorus were observed, largely as a result of uptake by micro-organisms on decomposing leaves and by algae.

The data set consists of the Adirondack lakes Survey Corporation data collected on 1469 lakes during 1984-87. Two models fitted to a randomly selected development subset of lakes, using 2 sets of candidate explanatory/predictor variables of particular interest, were compared on the basis of coefficient consistency and predictive ability. In addition to the usual maximal likelihood logistic regression results, collinearity and other associated diagnostics and variable-selection procedures designed specifically for the logistic regression model were applied to arrive at parsimonious models. Both models correctly predicted fish presence in more than 85 per cent of the model development set and more than 80 per cent of the lakes in the verification data. For those variables appearing in both models, the signs of the estimated coefficients were the same and in agreement with expectation. The removal of influential observations, as indicated by the logistic regression diagnostics, caused all of the estimated coefficients to increase in absolute magnitude. This results in a model which is more sensitive to changes in the explanatory variables.

The coefficients were compared with sorption data predicted on the basis of the n-octanol/water partition coefficient of each compound. The results provided a basis for the extrapolation of sorption data for individual compounds to mixtures of compounds with high vapour pressures. Predictive equations were applicable when octanol/water partition coefficients were in a range of approximately 1-3. Beyond this range a correction factor might be required.

Snail grazing maintained a thin layer of periphyton dominated by Stigeoclonium basal cells, regardless of nutrient regime. Although nutrient effects on periphyton ash-free dry mass were statistically insignificant, nutrient additions significantly increased chlorophyll a, especially where snails were excluded. Snail densities were 89 per cent higher in nutrient-enriched channels. Photosynthesis-irradiance data suggested that nutrient enrichment increased self-shading in the periphyton. Areal-specific productivity was simultaneously limited by grazing and low nutrient concentrations: snail exclusion and nutrient enrichment both increased productivity more than twice. The negative effects of snails on areal-specific productivity was due to reduction in biomass by cropping and depression of chlorophyll-specific productivity. The way which Elimia depresses chlorophyll-specific productivity is unclear, but the depression is clearly disadvantageous to food-limited grazers. Because Elimia was the dominant invertebrate, results indicated that low nutrient concentrations limit secondary and primary production in autumn. There are 59 references.

Several improvements of the RTP technique were investigated. Two approaches that were investigated to detect improvements were the second-derivative technique and the synchronous scanning technique. The second derivative method was used to overcome the problem of the frequent occurrence of broad emission bands in RTP spectra. The effects of several phosphorescence enhancers (beta-cyclodextrin, flumed silica, sodium dodecyl sulphate) were studied to improve sensitivity. Data showed that soil samples containing PCB with higher chlorine content had the highest limit of detection values suggesting an internal heavy atom suppression of the RTP signal. The RTP technique was simple and efficient for screening of PCB in soil samples.

AN - 72582347; 1761567 AB - Numerous candidates have been suggested according to chemical and structural criteria for the active site base of ribulose bisphosphate carboxylase/oxygenase that catalyzes substrate enolization. We evaluate the functional significance of two such candidates, His-321 and Ser-368 of the Rhodospirillum rubrum enzyme, by site-directed mutagenesis. Position 321 mutants retain 3-12% of wild-type rates of both overall carboxylation and the initial enolization, with little effect on Km for CO2 or ribulose bisphosphate. Position 368 mutants exhibit approximately 1% of wild-type carboxylation but 4-9% of enolization, also accompanied by little effect on Km values. The modest catalytic facilitations elicited by these residues are incompatible with either acting as the crucial base. The enhanced efficiency of the position 368 mutants in enolization versus carboxylation clearly indicates that Ser-368 effects catalysis preferentially beyond the point of proton abstraction. Both sets of mutants bind the reaction intermediate analogue, 2-carboxy-D-arabinitol bisphosphate, stoichiometrically. Ligand exchange from complexes with position 321 mutants is increased relative to wild type, whereas complexes with position 368 mutants are more exchange-inert. Therefore, His-321 may assist stabilization of the transition state mimicked by the analogue.

AN - 72494271; 1961922 AB - A model for damage, repair, killing, and repopulation of myelopoietic marrow is presented. Evaluation produces time and dose-rate profiles during and following any complex irradiation. Equations model variable dose rates, multiple exposures, different sources, and arbitrary intervals between treatments. If factors which dominate the control of biological processes can be demonstrated, an option is to set biological rate constants to experimentally determined values. Previously, knowledge did not permit identification of dominating biological processes and their temporal rates. But a unique feature of this study is that unspecified lesions for killing and injury of cells are evaluated from mortality data on the animal species of choice. "Unspecified" is used to indicate a condition of assumption-free modeling of molecular processes, whereby rate constants for cellular effects are simply computed directly from animal mortality data. Coefficients (estimated by maximum-likelihood methods for nonspecific processes) are compared with experimental values for specific processes. The model has many uses, including modeling of the myelopoietic potential as a function of time. Another option is to calculate the whole-body survival curve for cells that control myelopoiesis as a result of the treatment schedule. Also through simple extensions of the model, an extremely complex protocol can be identified with an equivalent prompt dose value--even for partial-body, fractionated exposures.

To evaluate the possible increase in atmospheric CO sub(2) with and without fertilization, we adopt a "business-as-usual" scenario of anthropogenic CO sub(2) emission. Such increase is computed from the atmospheric pCO sub(2) in the ocean-atmosphere total C system as it responds to this emission scenario. Assuming completely successful Fe fertilization, we calculate an 8% atmospheric CO sub(2) reduction for a case with a 3 cm super(2) s super(1) vertical diffusivity and 17.4 Sv upwelling flux, as derived from distribution of bomb- super(14)C in the ocean. Hence, if atmospheric pCO sub(2) reaches 800 mu atm in the next century, the maximum possible reduction is 64 mu atm. Doubling of upwelling flux to 34.8 Sv results in a reduction of 96 mu atm. If we assume the surface area of the Antarctic Ocean is 16% of the total ocean area instead of 10% as used in the standard case, the reduction is 71 mu atm. These results are independent of the respiration function adopted. As we hold the surface water PO sub(4) content at a near-zero value, it makes no difference at what depth the organic material is oxidized (or whether it falls to the bottom and accumulates). Changes in the gas exchange rate over the Antarctic Ocean also do not have a significant effect on the magnitude of atmospheric CO sub(2) drawdown. Doubling the gas exchange rate in the Antarctic region after fertilization results in a reduction of 68 mu atm. Doubling of vertical diffusivity to 6 cm super(2) s super(1) in Antarctic deep water yields a reduction of 75 mu atm. The key parameters are the rate of upwelling in the Antarctic and the fate of this upwelled water. The length of the productive season influences the extent of pCO sub(2) reduction. For 8 months of productive fertilization our model yields a reduction of 60 mu atm, for 4 months a reduction of 50 mu atm, and for 2 months a reduction of 40 mu atm. The maximum O sub(2) consumption in our standard case is estimated to be 133 mu mol kg super(1) at a depth of 600 m. However, O sub(2) consumption depends on the reoxidation function in the subsurface water. If the organic flux reoxidizes completely in the upper 2,000 m, the maximum consumption of O sub(2) at 500 m could reach 500 mu mol kg super(1). Hence, depending on the reoxidation function, an anoxic Antarctic thermocline could result from Fe fertilization. Both calculations regarding the seasonality of production and those regarding oxygen reduction are highly sensitive to parameters over which we have little control. They are included only to emphasize their potential importance.

AN - 72696822; 1800899 AB - We use a method of relative potency comparisons to rank the potential strength of 44 compounds being tested in rodent carcinogenicity bioassays. All of our previous hazard evaluations have been for human conditions where great numbers of simultaneous and serial exposures may act in combination to produce a neoplasm comprised of 2(20) to 2(30) cells commonly expected to derive from a single precancerous cell. For human exposures, we have always assumed an initiated target tissue containing at least one transformed but subcarcinogenic cell per organ. Thus, for man we have focused on empirical correspondences that may help to index the monoclonal growth of a particular cell lineage during cancer expansion. In contrast to humans, initiation of target tissues in animals subjected to National Toxicity Program (NTP) bioassays may not be a given condition, because of extensive precautions taken to minimize exposures to contaminates in food, water and cage environments. For this evaluation, we used categorical assignments of 'unlikely', 'possible' and 'probable' carcinogens adapted from NTP tests. Our rank ordering, of compounds according to maximum doses tested in male mice and male rats, is coded accordingly to the three outcomes taken from the NTP tests, but the magnitude of potency depend completely upon our particular method of comparing toxicological data. We have attempted to demonstrate that a relative potency based analysis of a diversity of toxicological data may be useful for rank ordering potentially hazardous compounds to be tested by the NTP and for range-finding of their effective test doses to be administered during chronic test protocols.

(P-I) curves for four developmental stages from each location were constructed from super(14)C uptake at six irradiances (22-1,100 mu mol quanta m super(2) s super(1)) in the laboratory. Photoinhibition in the periphyton from the two shaded sites declined with development, indicating that self-shading significantly influenced photosynthesis in older communities. Photoinhibition was absent, however, in all of the developmental stages from the high light site. Maximum photosynthesis (P sub(max)) and slope ( alpha ) of the light-limited portion of the chlorophyll-specific light response decreased >40% in developing periphyton at all sites. Significant negative correlations between biomass and biomass-specific P sub(max) suggested that light or metabolic substrates became progressively more limiting during development. Although there was little community-level evidence of shade adaptation during development (photosynthesis did not saturate at lower light intensities as development proceeded), periphyton understories appear to retain considerable photosynthetic potential despite significant shading by upper layers.

AN - 72129635; 1917489 AB - This paper discusses the historical development of standards for limiting routine radiation exposures of workers and the public. The radiobiological and epidemiological basis for radiation protection standards and practices, as this basis has evolved over time, is emphasized. Difficulties with using dose equivalents and nominal risk factors, which were developed primarily for purposes of radiation protection (i.e., to establish dose limits), in estimating radiation risks at the low levels of exposure routinely experienced in the workplace and the environment are discussed. The increasing importance of the principle that exposures should be reduced as low as reasonably achievable (ALARA) in radiation protection of workers and the public is described.

AN - 72656686; 1795638 AB - The search for a short-term mutagenicity test to identify potential carcinogens has yielded over 100 assay systems, including the Ames test. This paper continues the investigation of Travis et al. into the prediction of carcinogenic potency of known mouse carcinogens using different classes of short-term toxicologic data. We used four classes of short-term test data (mutation, toxicity, reproduction and tumorigenicity) from the Registry of Toxic Effects of Chemical Substances (RTECS) database. We conclude that mutation data alone are poor predictors of carcinogenic potency, accounting for only 21% of the observed variability in experimentally-determined mouse TD50 values. We further conclude that batteries of toxicologic data containing varying types of short-term data are excellent predictors of the carcinogenic potency of known mouse carcinogens: four types of short-term data account for 82% of the observed variability in experimentally-obtained mouse TD50 values. By using all available toxicological data, we obtained a strong correlation between toxicologic assay results and carcinogenic potency of known mouse carcinogens.

AN - 72464704; 1944357 AB - Exposure of mouse zygotes to ethylene oxide (EtO) or ethyl methanesulfonate (EMS) led to high incidences of fetal death and of certain classes of fetal malformations (Generoso et al., 1987, 1988; Rutledge and Generoso, 1989). These effects were not associated with induced chromosomal aberrations (Katoh et al., 1989) nor are they likely to be caused by gene mutations (Generoso et al., 1990). Nevertheless, the anomalies observed in these studies resemble the large class of stillbirths and sporadic defects in humans that are of unknown etiology, such as cleft palate, omphalocoel, clubfoot, hydrops and stillbirths (Czeizel, 1985; Oakley, 1986). Therefore, we continue to study the possible mechanisms relating to induction of these types of zygote-derived anomalies in mice. Effects of zygote exposure to the compounds methyl methanesulfonate (MMS), dimethyl sulfate (DMS), and diethyl sulfate (DES), which have similar DNA-binding properties as EtO and EMS, were studied. DMS and DES, but not MMS, induced effects that are similar to those induced by EtO and EMS. Thus, no site-specific alkylation product was identifiable as the critical target for these zygote-derived anomalies.

AN - 80690446; 2072978 AB - Female mice were exposed to 300 R of 73-93 R/min X-radiation either as fetuses at 18.5 d post conception (p.c.) or within 9 h after birth. Combining the similar results from these two groups yielded a specific-locus mutation frequency of 9.4 X 10(-8) mutation/locus/R, which is statistically significantly higher than the historical-control mutation frequency, but much lower than the rate obtained by irradiating mature and maturing oocytes in adults. Other females, exposed at 18.5 days p.c. to 300 R of 0.79 R/min gamma-radiation, yielded a mutation frequency that was statistically significantly lower than the frequency at high dose rates. The low-dose-rate group also had markedly higher fertility. It appears that the dose-rate effect for mutations induced near the time of birth may be more pronounced than that reported for mature and maturing oocytes of adults. A hypothesis sometimes advanced to explain low mutation frequencies recovered from cell populations that experience considerable radiation-induced cell killing is that there is selection against mutant cells. The reason for the relatively low mutational response following acute irradiation in our experiments is unknown; however, the finding of a dose-rate effect in these oocytes in the presence of only minor radiation-induced cell killing (as judged from fertility) makes it seem unlikely that selection was responsible for the low mutational response following acute exposure. Had selection been an important factor, the mutation frequency should have increased when oocyte killing was markedly reduced.

Possible explanation for the effect. AN - 80689780; 2072977 AB - Male mice were exposed to [3H]EtO by inhalation at different exposure rates (300 parts per million (ppm) of EtO for 1 h: 150 ppm for 2 h: 75 ppm for 4 h). The total exposure was fixed at 300 ppm-h. The amount of EtO binding to developing spermatogenic stages, to sperm DNA, to testis DNA and to hemoglobin was then measured as a function of the EtO exposure rate. Generally, as the exposure rate increased there was an increase in the amount of EtO binding to the targets. For example, alkylation of sperm from the caudal epididymides 6 d posttreatment, of DNA from the vas sperm (averaged over 4 time points), of testis DNA (90 min posttreatment), and of hemoglobin (averaged over 4 time points), was 2.0 +/- 0.2 (SD), 1.8 +/- 0.4, 2.9 +/- 0.3, and 1.5 +/- 0.1 times greater, respectively, after an exposure to 300 ppm for 1 h than after an exposure to 75 ppm for 4 h. The testicular DNA from animals exposed to 300 ppm of [3H]EtO for 1 h was also analyzed for the presence of N7-hydroxyethylguanine (N7HEG) and O6-hydroxyethylguanine (O6HEG). The half-life (T1 2) of the N7HEG in the testis DNA was calculated to be 2.8 d. This lesion was removed relatively rapidly from the testis DNA and was probably excised by enzymatic repair. No formation of O6HEG was detected in any of the testis DNA samples analyzed. Additional experiments showed that the exposure rate effect was the result of less total EtO being taken in by the mice over long exposure times compared to that taken in during shorter exposure times at higher concentrations. This result argues against the idea that the exposure rate effect is the result of physiological/enzymological changes affecting transport or metabolism of the chemical within the animals under different exposure rate conditions.

AN - 80689495; 2072973 AB - In a previous report (Generoso et al., 1985) it was shown that the two hybrid stocks of mice, (C3H/R1 x 101/R1)F1 and (SEC/R1 x C57BL/6)F1, differed in their responses to induction of chromosomal aberrations following exposure of the stem-cell spermatogonia to 500 R x 4 (4-week intervals) acute X-rays. The levels of response in the two stocks were paralleled by the effects on the length of the sterile period, which presumably results from stem-cell killing and repopulation. The present study was conducted in order to determine whether the differences between the two stocks in these parameters hold true also for other conditions of radiation exposure. Thus, comparative experiments were conducted using the following acute exposure regimens: 500 R single dose, 500 R + 500 R (24-h interval), 100 R + 900 R (24-h interval), and 500 R x 4 (8-week intervals). The endpoints measured were chromosome rearrangements in diakinesis/metaphase-I meiocytes, embryonic lethality in conceptuses, length of sterile period and testis weight. Trend analysis indicated that higher frequencies of chromosome rearrangements and embryonic lethality were recovered from (C3H/R1 x 101/R1)F1 than from (SEC/R1 x C57BL/6)F1 males, that there were no significant differences between stocks in testis weight reductions, and that there was no consistency in the direction of the significant differences that occurred in the length of the sterile period. A definitive conclusion regarding the possible association between induction of chromosomal aberrations and induction of cell killing awaits direct histological analysis of the stem-cell population.

AN - 72501512; 1958072 AB - Protocols for long-term carcinogen bioassays have become highly refined. The ability to interpret these bioassay results beyond the experimental setting, however, has not improved commensurately. As a consequence, society is still faced with the fact that data derived in these bioassays reflect highly specific experimental conditions which are vastly different from environmental exposures of the freely roaming, outbred human. The scientific community has responded with a "collective wisdom" approach by using expert committees to interpret bioassay evidence. This committee approach is believed to be successful in protecting human health, but the list of suspected carcinogens is growing faster than the expert committees can respond. We have developed a relative potency framework for ranking the hazards represented by potential human carcinogens. The results demonstrate a rank ordering of a variety of compounds which is independent of the reference compound used to standardize the information. The philosophic basis of the approach may facilitate expert risk assessment systems development because it: (1) complements and supports "expert committee" data selection; (2) has a simple set of rules and does not require mathematical modeling; (3) requires no special situation judgments; and (4) is suitable for use with electronic data bases.

I. Similar, nonrandom distribution of mutations in unirradiated and X-irradiated DNA. AN - 72463653; 1947004 AB - The Escherichia coli supF gene encoding the suppressor tyrosine tRNA in a human shuttle plasmid, pZ189, was used as a target for molecular analysis of X-ray-induced mutations in human lymphoblastoid cells. Following replication of the in vitro-irradiated plasmid in human cells, the mutant supF-containing molecules were cloned by phenotypic screening in E. coli and the nature of the mutations was determined by direct sequencing of the tRNA gene. At 160 Gy the mutant frequency was 13 times (0.39%) that observed in unirradiated controls (0.031%). When control plasmid was replicated directly in E. coli, the mutant frequency was 16 times less than that of the plasmid passaged through the human cells. The distribution of mutations was highly nonrandom and remarkably similar in both irradiated and control DNAs. The majority of the mutations were transitions involving G.C pairs and occurred selectively at most 5'-TC (3'-AG) sequences. These mutations at C's were preferentially distributed in the nontranscribed strand. We propose that mutations in the control plasmid result from oxidative damages that occur during and/or after its incorporation into human cells and that these damages are similar to those induced by ionizing radiation. The hot spots for mutations suggest that the proximate nucleotide sequence and the overall conformation of the target DNA are important in the production and/or processing of these damages during repair and replication.

The results indicate that the alveolar concentration necessary to produce anesthesia is approximately constant across species. Because alveolar ventilation rates scale with the 0.75 power of body weight, this implies that administered dose mea sured in mg/kg super(0.75)/day produces the same anesthetic effect in all species. This analysis provides further support for the use of a mg/kg super(0.75)/day interspecies scaling metric for acute toxic effects.

AN - 80678964; 1648803 AB - Multiple data sets on hepatocarcinogenesis in rats resulting from pulse (single) or continuous exposure to diethylnitrosamine (DEN) are analyzed within the framework of a two-mutation carcinogenesis model in order to identify the underlying biological processes that control the pharmacodynamics of DEN-induced liver cancer. Our findings indicate: (1) Predictions of the two-mutation oncogenic model are consistent with empirical data on DEN-induced hepatocarcinogenesis. (2) The probability of the first genetic alteration (initiation) is linearly dependent on applied dose and decays exponentially following a pulse (single) dose or cessation of exposure. (3) The probability of initiation is proportional to the number of O4-ethyldeoxythymidine DNA adducts resulting from DEN exposure, indicating that these adducts are the likely promutagenic lesions in DEN-induced hepatocarcinogenesis. (4) The mitotic rates of initiated and transformed cells are nonlinear with dose. (5) The average growth rate of initiated hepatocytes as a function of DEN dose is related to Druckery's slope. (6) The probability of the second genetic event (transformation) is independent of applied dose, suggesting that it is the result of a spontaneous genetic alteration.

AN - 80579852; 1645355 AB - The Calvin Cycle enzyme phosphoribulokinase is activated in higher plants by the reversible reduction of a disulfide bond, which is located at the active site. To determine the possible contribution of the two regulatory residues (Cys16 and Cys55) to catalysis, site-directed mutagenesis has been used to replace each of them in the spinach enzyme with serine or alanine. The only other cysteinyl residues of the kinase, Cys244 and Cys250, were also replaced individually by serine or alanine. A comparison of specific activities of native and mutant enzymes reveals that substitutions at positions 244 or 250 are inconsequential. The position 16 mutants retain 45-90% of the wild-type activity and display normal Km values for both ATP and ribulose 5-phosphate. In contrast, substitution at position 55 results in 85-95% loss of wild-type activity, with less than a 2-fold increase in the Km for ATP and a 4-8-fold increase in the Km for ribulose 5-phosphate. These results are consistent with moderate facilitation of catalysis by Cys55 and demonstrate that the other three cysteinyl residues do not contribute significantly either to structure or catalysis. The enhanced stability, relative to wild-type enzyme, of the Ser16 mutant protein to a sulfhydryl reagent supports earlier suggestions that Cys16 is the initial target of the oxidative deactivation process.

Algal biomass ranged from 2.3 to 86 mu g Chl a cm super(-2) and taxonomic composition differed. Photoassimilation of super(14)C was measured in the laboratory at six light levels for each community. Photosynthesis by communities from shaded sites was photoinhibited at the highest light level. The light intensity at the onset of saturation (Ik) was positively correlated (P less than or equal to 0.05) with ambient light, but ranged only from 100 to 400 mu mol m super(-2) s super(-1) among communities. Light-saturated, Chl-specific photosynthetic rates (PS super(Chl)M) ranged from 0.26 to 1.4 mu g C( mu g Chl a) super(-1) h super(-1). The initial slope ( alpha ) of the P-I response ranged from 0.80 to 6.4 mu g C (mg Chl a) super(-1) ( mu mol quanta) super(-1) m super(-2) s super(-1). Unlike phytoplankton, alpha and PS sub(M), (per unit Chl a) of the periphyton communities were not well related to the ambient light environment and tended to be lower for communities from high-light habitats. Further, the P-I responses of the communities were better related to periphyton biomass than to the light environment. Self-shading and other aspects of development in a matrix seem to be important determinants of periphyton P-I relationships.

AN - 80558018; 2030709 AB - The two parental genomes lie separate within the zygote and may be differentially affected by environmental influences. We have shown earlier (Russell et al., 1988) that the maternal genome within the mouse zygote is exquisitely sensitive to the induction of point mutations by N-ethyl-N-nitrosourea (ENU), and that the initial lesion probably occurs in one strand of the DNA. The present experiment measured specific-locus mutation induction in the paternal genome. Zygotes containing a multiple-recessive maternal genome (a; b; p cch; d se; s) and the corresponding wild-type alleles in the paternal one were exposed to 50 mg ENU/kg in vivo at one of two stages: the presumed times of sperm entry and early pronuclear stage. At weaning age, the resulting mice were examined for mutations at the marked loci as well as for other mutations producing externally visible phenotypes. At the marked loci, one possible mosaic (for b) was observed among 2113 classified offspring that had been treated with ENU as zygotes; this animal failed to transmit a mutation. By contrast, in the reciprocal cross (which tests the maternal genome) we had observed 8 specific-locus mutations (6 of them mosaics) among 1555 offspring that had received the same dose of ENU during sperm entry (and completion of oocyte meiosis II). In the present experiment, we also found one mutation at other loci (two at other loci in the reciprocal cross). The frequency of offspring with small white belly spots was significantly greater in the treated groups (3.5 and 1.9% at the earlier and later stage, respectively) than in the control (1.0%), the excess being almost entirely due to daughters. Genetic tests of a large number of such offspring failed to find a genetic cause. Instead, it appears that this phenotype may be influenced by factors in the intrauterine environment. It is concluded that shortly after sperm entry, the paternal genome of the zygote is less sensitive than the maternal one to the induction of mutations by ENU.

AN - 80516241; 1850095 AB - The third disulfide loop (amino acids 33 to 42) of human epidermal growth factor (hEGF) encompasses the region of highest amino acid conservation among all of the EGF-like family of molecules. The importance of some of these highly conserved residues for the maintenance of biological activity, especially the aromatic amino acid tyrosine at position 37, has until now been considered essential on the basis of previous studies with the EGF-like molecule transforming growth factor alpha. Variants at the Tyr-37 position of hEGF were constructed by site-directed mutagenesis. The substituting amino acids were phenylalanine, histidine, serine, alanine, aspartic acid, arginine, and glycine. The variants were tested for their ability to competitively displace native [125I]hEGF from its receptor and to stimulate the protein-tyrosine kinase activity of the receptor; the order of efficacy of substituting amino acids was Phe greater than His greater than Ser greater than Ala greater than Asp greater than Arg greater than Gly in both assays. All were effective, with no or only moderate reduction in potency, in stimulating the incorporation of [3H]thymidine into acid-insoluble material of quiescent mouse A31 cells. Only Tyr-37----Ala, Tyr-37----Arg and Tyr-37----Gly were slightly less potent in the cell assay.

AN - 80511811; 2015666 AB - This paper presents the application of a fiber-optic antibody-based fluoroimmunosensor (FIS) for measuring DNA adducts of benzo[alpha]pyrene in human placenta samples. The FIS combines the excellent specificity of the antigen-antibody reaction, the high sensitivity of laser excitation, and the versatility of fiber-optic technology. The FIS was used to detect benzo[alpha]pyrene tetrol (BPT) after release from DNA by mild acid hydrolysis. These placenta samples contained one molecule of adduct per 10(7) base pairs. The limit of detection of the FIS for BPT is about 14 amol (14 x 10(-18) mol).

AN - 80466244; 2001948 AB - A linear compartment model for global transport of iodine that we previously developed predicted that the mean residence time of iodine in the first 1 m of surface soil is about 4,000 y. An independent test of the model prediction is provided by measured depth profiles of (129)I in soil following atmospheric releases from the Savannah River Plant (SRP) in South Carolina and from the Karlsruhe fuel reprocessing plant in Germany. Previous analyses of these data using a linear compartment model for downward transport through soil indicated that the mean residence time in the first 0.3 m is about 40 y at both locations, which suggests that removal of (129)I from surface soil may be considerably more rapid than predicted by the global transport model. In this paper, a diffusion model is used to describe the measured soil profiles of (129)I at Savannah River. The diffusion coefficient obtained from the analysis corresponds to a mean residence time in the first 1 m of surface soil that agrees semi-quantitatively with the prediction of the global model when the concentration of naturally occurring stable iodine in soil and the flux of iodine from the atmosphere onto surface soil at Savannah River, as they differ from globally averaged values, are considered. This paper also discusses (1) the importance of the mean residence time of (129)I in surface soil for estimates of dose to individuals from near-surface land disposal of low-level radioactive wastes and (2) unresolved issues regarding global cycling of iodine.

AN - 80447730; 1995509 AB - The Ultrasonic Ranging and Data System (USRADS) was developed to allow radiation exposure rate data and positional information to be simultaneously collected, stored, and analyzed in a manner more efficient than conventional survey techniques. USRADS is field portable using ultrasonics to locate a field surveyor on a site and radiofrequency to transmit data. Surveyor position (e.g., measurement location within 10 cm) and an integrated instrument measurement are recorded and stored once each second in a microcomputer. Operational experience indicates that the system results in collection of greater quantity and higher quality of radiological data with less effort in data transcription and analysis and only slightly more field effort compared to conventional manual methods.

AN - 80461554; 2000095 AB - Acrylamide monomer (AA), injected into male mice at the maximum tolerated dose of 5 x 50 mg/kg (24-h intervals), significantly increased the specific-locus mutation rate in certain poststem-cell stages of spermatogenesis, but not in spermatogonial stem cells. Germ-cell stages in which the treatment induced dominant lethals--namely, exposed spermatozoa and late spermatids (number of surviving offspring only 3% and 27%, respectively, of those in concurrent controls)--jointly yielded the highest frequency of specific-locus mutations. AA thus conforms to Pattern 1 in our earlier classification of chemicals according to the spermatogenic stage at which they elicit maximum response (Russell et al., 1990). No specific-locus mutations were observed among 17,112 offspring derived from exposed spermatogonial stem cells, a result which rules out (at the 5% significance level) an induced mutation rate greater than 2.3 times the historical control rate. A sustained high productivity in matings made for several months following week 3 indicates that there is no significant spermatogonial killing and that cell selection is presumably not the explanation for the negative result. On the basis of genetic and/or cytogenetic evidence, the mutations induced postmeiotically by AA were 'large lesions' (multi-locus), while one of 2 recovered from exposure of differentiating spermatogonia is probably a small lesion. An earlier survey of mammalian mutagenesis results led us to conclude that, regardless of the classification of a chemical according to the stage at which it elicits its maximum response, the nature of mutations is determined by the germ-cell stage in which they are induced (Russell et al., 1990). The AA results on lesion size and on distribution of mutations among the loci fit the general pattern.

AN - 80429520; 1989940 AB - Indoor Rn concentrations and Rn in adjacent karst terrains were studied at four houses with crawlspaces in Huntsville, AL. In warm summertime weather, Rn-rich air may vent through limestone solution cavities exposed as holes at the surface of the properties. A probable interrelated-finding is that the indoor levels of 222Rn are distinctly higher in the summer than winter. The karst underlying the homes is structurally faulted and, in all probability, facilitates Rn transport from the solution cavities to the crawlspaces. Abrupt day-to-day changes in indoor Rn concentrations were recorded in addition to large seasonal changes. If the owners or residents of these particular homes had attempted to make, and interpret, short-term screening measurements for Rn during the fall season, problems, including false negatives, could have arisen because of order-of-magnitude changes in Rn concentration occurring over a few days. The best time of year to make screening measurements would be during the summer when indoor Rn concentrations are more likely to reach their maximum values.

AN - 80624260; 2052206 AB - Several molecular and biochemical markers of genotoxicity were adapted for measurement in the medaka, and were used to describe the effects of treatment of the organism with diethylnitrosamine (DEN). DEN treatment inhibited the activity of a detoxication enzyme activity (ethoxyresorufin-O-deethylase) and increased the activity of glutathione-S-transferase. This pattern of response has been described in preneoplastic rodent cells. No O6-ethyl guanine adducts were detected, and a slight, but statistically significant, increase in DNA strand breaks was observed. These results are consistent with the hypothesis that prolonged exposure to high levels of DEN induced alkyltransferase activity which enzymatically removes any O6-ethyl guanine adducts but does not result in strand breaks or hypomethylation of the DNA such as might be expected from excision repair of chemically modified DNA.

AN - 80450801; 1996907 AB - This study was undertaken to develop a common scale for evaluating health risks from contaminated drinking water. For different agents, many unrealistic models of risk have been used. By intent, regulatory toxicology depends on "data-sparse, model-intensive" analogies from exotic animal genetics and novel exposures (NCRP 1989). The question is, does a risk evaluation so derived have any predictive validity? Absence of data prevents answer because regulatory toxicology rationalizes in step-by-step logic, which we call absolute (i.e., predicts cases of disease in a population). Absolute models ensure safety, but do so at the cost of realism. In contrast, we make relative comparisons in the manner of horsepower or RBE from radiation biology. All pollutants are assumed to contribute to toxic injury. Next, relative potencies are linked to the most credible standards. Thus, experience is transferred from well-studied chemicals to the new chemical by "data-intensive, model-sparse" methods. This logos provides much relative precision. Then, pollutants are compared with: (1) common foodstuffs, (2) ambient radiation background, or (3) utility-pure drinking water. Finally, an assessment is made for a waste disposal area.

AN - 80438059; 1992495 AB - The merit of using small mammals as monitors of environmental contaminants was assessed using data from the published literature. Information was located on 35 species of small mammals from 7 families used to monitor heavy metals, radionuclides, and organic chemicals at mine sites, industrial areas, hazardous and radioactive waste disposal sites, and agricultural and forested land. To document foodchain transfer of chemicals, concentrations in soil, vegetation, and invertebrates, where available, were included. The most commonly trapped North American species were Peromyscus leucopus, Blarina brevicauda, and Microtus pennsylvanicus. In these species, exposure to chemicals was determined from tissue residue analyses, biochemical assays, and cytogenetic assays. Where enough information was available, suitable target tissues, or biological assays for specific chemicals were noted. In general, there was a relationship between concentrations of contaminants in the soil or food, and concentrations in target tissues of several species. This relationship was most obvious for the nonessential heavy metals, cadmium, lead, and mercury and for fluoride. Kidney was the single best tissue for residue analyses of inorganic contaminants. However, bone should be the tissue of choice for both lead and fluorine. Exposure to lead was also successfully documented using biochemical and histopathological endpoints. Bone was the tissue of choice for exposure to 90Sr, whereas muscle was an appropriate tissue for 137Cs. For organic contaminants, exposure endpoints depended on the chemical(s) of concern. Liver and whole-body residue analyses, as well as enzyme changes, organ histology, genotoxicity, and, in one case, population dynamics, were successfully used to document exposure to these contaminants. Based on information in these studies, each species' suitability as a monitor for a specific contaminant or type of contaminant was evaluated and subsequently ranked. A relationship between contaminant exposure and trophic level emerged. Insectivores (shrews) had the highest levels of contaminants, followed by omnivores (cricetid mice) with intermediate levels, and herbivores (voles) with the lowest levels. A substantial number of these biomonitoring studies using small mammals collectively point to the importance of food habits and habitat of small mammals, and their availability and abundance as factors that should influence species selection for monitoring studies. The type of contaminants under consideration as well as the appropriateness of the endpoints selected are important factors to consider when deciding whether or not to include small mammals in biomonitoring studies.

AN - 80419169; 1988186 AB - Chinese hamster ovary cells with no detectable (less than 200 molecules/cell) O6-methylguanine-DNA methyltransferase (EC 2.1.1.63) were transfected with human cell DNA and pSV2neo plasmid by electroporation. Two stable transformant clones, GC-1 and GC-2, containing 4 X 10(4) and 4-6 X 10(3) methyltransferase molecules/cell respectively were isolated by successive screening in the presence of G418 and 2-chloroethyl-N-nitrosourea (CNU). Only three or four copies of pSV2neo DNA and no repetitive human DNA sequence were detected in these isolates. Secondary transfection of parent cells with GC-1 DNA yielded several clones containing 2-10 X 10(3) methyltransferase molecules/cell. The rate of removal of O6-methylguanine in GC-1, GC-2 and parent cells in vivo reflected their methyltransferase levels, while the N-methylpurines were removed at similar rates in all three cell lines. The differential sensitivity of these cells to several alkylating agents, namely CNU, N-methyl-N-nitrosourea, N-methyl-N'-nitro-N-nitrosoguanidine and methyl-methane sulfonate (MMS), known to yield different proportions of O6-alkylguanine among the alkyl adducts in DNA, varied widely. The largest and smallest differences in toxic response were observed with CNU and MMS respectively. These cell lines showed no difference in sensitivity to the DNA cross-linking agent psoralen. These data strongly suggest that alkylating agents produce two classes of lethal lesions, one of which is O6-alkylguanine. Induction of mutations at the hypoxanthine-phosphoribosyltransferase locus in these cells lines suggests that, regardless of its relative yield, O6-methylguanine is the major mutagenic lesion for all alkylating agents.

AN - 80365739; 1986266 AB - Male and female gametogeneses differ markedly in all mammals. While male germ cells are continuously being produced from stem cells throughout the reproductive life span, the number of female germ cells is fixed during prenatal development and, soon after birth, all of the oocytes are arrested in a modified diplotene, or dictyate, stage. Following puberty, dictyate oocytes are hormonally triggered to mature either singly or in groups, resulting in ovulation and the completion of the first meiotic division. It has been hypothesized that female mice are more susceptible to dominant lethal effects of intercalating agents than male mice because oocyte chromosomes, which are arrested in a diffuse state, are generally more accessable to intercalation than are the more condensed chromosomes present within most male germ cell stages. This hypothesis was further tested using the intercalating agent hycanthone methane-sulfonate. Effects of hycanthone were studied in maturing and primordial oocytes and in male germ cells throughout spermatogenesis. No induction of dominant lethality was observed for treated males while a significant increase in embryonic death, expressed around the time of implantation, was observed in females that mated within 4.5 days after treatment. These effects were the result of dominant lethal mutations induced in maturing oocytes and not of maternal toxicity as indicated by the presence of chromosomal aberrations observed at first-cleavage metaphase of zygotes obtained from treated females. These results add support to the hypothesis that certain intercalating chemicals, which are not mutagenic to male mice, may be mutagenic to females and point to a need for more in-depth studies of female-specific mutagenesis.

AN - 72743990; 1820730 AB - This report provides an overview of one of the fundamental problems in cancer risk assessment: extrapolation of observed experimental results between animal species and man. Lacking detailed information on interspecific differences, researchers assume that experimental results can be extrapolated between species using the first power of body weight or using surface area scaling (body weight to 2/3 power). Neither of these extrapolation procedures will be exactly correct for all compounds. However, in the absence of species-specific data, body weight or surface area extrapolations are used with the explicit knowledge that they are only approximately correct. We recommend that when a scaling metric for a specific compound is known, the scaling metric should be used in a risk assessment. When there is no prior knowledge of a chemical's pharmacokinetics or mechanism of action (the usual case in risk assessment), we recommend that the 3/4 power of body weight be used as the most appropriate interspecies scaling metric. The methods and properties used in interspecies extrapolation include allometric scaling, scaling physiological parameters (organ volumes, volume rates, partition coefficients, and biological half-life), physiological time, and physiologically-based pharmacokinetics. The extrapolation of these physiological, biochemical, and metabolic parameters across species controls interspecific extrapolation of pharmacokinetics. We analyzed clearance and half-life data for several compounds in multiple species and determined that the 3/4 power scaling law provides a more accurate estimate of a compound's true scaling metric than does the surface area scaling metric or the first power of body weight scaling metric.

AN - 72571392; 1661718 AB - For the first time, a complete computer simulation of physical and chemical reactions at the molecular level has been used to calculate the yield of a chemical species resulting from irradiation of a biological molecule in aqueous solution. Specifically, when a solution of glycylglycine is irradiated anaerobically, an ammonia molecule is released by the action of a hydrated electron, which is produced by irradiation of water. In the computations, Monte Carlo techniques are used to simulate the statistical progression of molecular events as they are assumed to occur. These include the initial physical ionization and excitation of water molecules along a particle track in the liquid; the subsequent formation of free radicals and other species: and the random diffusion and chemical reactions of the species with each other, the solvent, and solute molecules. We have calculated and measured the yield of ammonia from irradiation of glycylglycine with 250 kVp x-rays as a function of glycylglycine concentration between 0.01 and 1.2 M. Excellent agreement is obtained between predicted and measured results. The literal simulation of events, combined with specific experimental measurements, offers a powerful new tool for studying mechanisms of radiation action and damage at the molecular level.

AN - 72544592; 1748094 AB - The morphological specific locus test (SLT), which allows the scoring of 2,000 loci/hr/person, has been in use for four decades for measuring mammalian germ-line mutation rates under various conditions of exposure. More recently, the SLT's capabilities for the qualitative characterization of mutations have been exploited. The large sets of mutations centered on specific loci that have been accumulated over the years, including sets of nested deletions, have provided prime material for fine-structure genetic analyses. Subsequent molecular entry to these regions has led to intensive physical/functional mapping of megabase segments of the genome. In turn, these investigations have generated genetic and molecular tools for analyzing individual mutations as to extent and nature of the genomic lesion. Using the results of such analyses, it has been shown that germ-cell-stage at which mutagenic treatment is administered, rather than the nature of the mutagen used, may be the chief determinant of the nature of genomic lesions. These and related quantitative findings now make it possible to optimize conditions for the use of mutagens in providing desired types of mutations as tools (e.g., high incidences of deletions or other rearrangements vs. high incidences of point mutations).

AN - 72487531; 1956945 AB - In mammals, variability in the genetic sensitivity of different germ-cell stages to mutagens could be the result of how much chemical reaches the different stages, what molecular targets may be affected in the different stages and whether or not repair of lesions occurs. In the mouse, several chemical mutagens have been found that cause their greatest genetic damage in late-spermatid and early-spermatozoa stages and that also bind very strongly to the protamine in these stages. Chemicals which are less genetically damaging to these stages have been found to have much less affinity for protamine. Furthermore, the level of chemical binding to DNA in late-spermatid and early-spermatozoa stages has not been correlated with the level of induced genetic damage, although DNA breakage in these sensitive stages has been shown to increase. This DNA damage is believed to indirectly result from chemical binding to sulfhydryl groups in protamine which prevents normal chromatin condensation within the sperm nucleus.

AN - 72486903; 1952626 AB - Genetic variants of the laboratory mouse can serve as useful models for hereditary deafness syndromes in humans. Recessive mutations at the shaker-1 (sh-1) and whirler (wi) loci, in chromosomes 7 and 4, respectively, both result in circling behavior and a deafness syndrome. In sh-1 homozygotes this deafness is associated with neurophysiological abnormalities that may be accompanied by structural abnormalities of the inner ear. Radiation-induced deletion mutations are being used in a strategy of reverse genetics to identify the genes defined by these mutations. Genetic analyses have refined the position of sh-1 to a chromosomal interval between break points of deletions involving the closely linked albino (c) locus. A cDNA encoding olfactory marker protein (OMP) and the anonymous locus D7OR1 have also been mapped to this interval. These clones contribute to the physical map of the sh-1 region and could be important for accessing the sh-1 gene itself. Similarly, we have identified a radiation-induced deletion of the brown (b) locus that covers the wi locus and two that do not. Thus, the wi locus has been located within a chromosome 4 interval defined by structural rearrangements, which should likewise aid in identifying closely linked molecular clones.

Dibenzothiophene was degraded via a sulfur-oxidizing pathway to 2,2'-dihydroxybiphenyl. No further metabolism of that compound was observed. Ethyl phenyl sulfide and diphenyl sulfide were degraded to the corresponding sulfones. A variety of products were formed from dibenzyl sulfide, presumably via free radical intermediates. Diphenyl disulfide and dibenzyl disulfide were cleaved to the corresponding thiols and other single-ring products. It was concluded that degradation of organic sulfur compounds by Paecilomyces involves an oxidative attack localized at the sulfur atom.

The spur for the review was the fear that the presence and concentration of arsenic in groundwater might be, respectively, more widespread and more intense than had hitherto been believed. The source of such a fear was improved sampling and analytical methods (which are discussed) whose application had suggested that the arsenical species previously fund, which had often been assumed to be the pentavalent form, might have been the far more toxic trivalent form. The occurrence of arsenic in all its forms in the environment is considered, with special reference to its geochemistry, adsorptions onto various rock materials, biological transformations leading to the formation of organic arsenicals and the overall mechanism whereby arsenic may occur in alluvial systems and the groundwater derived from them. Where iron oxides in the alluvium have adsorbed and mobilized arsenical species, groundwaters could contain arsenic at several hundred micrograms per litre and such levels, while probably tolerable in regional water systems where blending of water is likely, could pose dangers to small communities or individuals not benefiting from such admixtures.

Triple-completion wells were able to define the groundwater pollution plume caused by chlorinated solvents beginning at the capillary fringe and moving to deeper levels along the path of the groundwater flow. The well which revealed high concentrations in its upper zone was close to the source. The creation of a multiple-completion well was about 10 per cent more costly than for a simple well.

The extent of background contamination in various countries is tabulated. Accumulation in plants is considered with attention to atmospheric deposition, root uptake and air-to-lead transfer. Accumulations in beef, milk, fish and eggs are also discussed. Estimates of human exposure to TCDD are made. The relative contributions of municipal solid waste incinerators, hospital waste incinerators, motor vehicles, wood burning and pulp mills are considered.

Chemicals produced either intentionally or as by-products of industrial activities eventually reached the environment, unless destroyed naturally or by human action. Thereafter they were subject to global transport and partitioning into biological media, resulting in a general exposure of the world's population to trace levels of chemical contaminants. It is argued that ambient levels of pollution have begun to affect human health on a global scale. PCB, dioxins, benzene, mercury and lead are discussed as examples of global pollutants. Health risks, regulatory approaches to the problem and methods of reducing risk are also reviewed. There are 50 references.

For maintenance of cultures, the 2 tests required approximately equal effort (FHM, 5.6 ph/t; CD, 5.8 ph/t). For a test consisting of 6 samples (including a control), 6.9 ph/t were required for FHM and 5.8 ph/t for CD. Effort required for other tasks was: 7.0 ph/t for water chemistry analyses; 5.5 ph /t for test preparation and dismantling; 6.0 ph/t for report writing; 7.0 ph/t for sampling; and 4 ph/t for quality assurance /control. Total effort required was 53.6 ph/t; at least 4 people would be needed to perform all of the tasks. Cost-effectiveness of culturing versus purchasing of the organisms is discussed.

The relationship of gauge density, gauge arrangement, catchment area, storm pattern and AMP error was then determined. A method was also proposed for the prediction of the magnitude and bias of error on the basis of commonly-available data. The results for one of the storms considered suggested that there is a 25 per cent chance of overestimating AMP by 11 per cent or more and a 25 per cent chance of under-estimating AMP by 26 per cent or more.

Monte Carlo analysis under regional variability AN - 13720836; 199200599 AB - Monte Carlo simulations were used in combination with input mapping to vary selected fundamental inputs and generate 100 iterations for the input values and predictions of the Integrated Lake Watershed Acidification Study (ILWAS), Model of Acidification of Groundwater in Catchments (MAGIC) and Enhanced Trickle Down (ETD) catchment acidification models for 2 dissimilar catchments under 4 different sulphate deposition scenarios. Comparison of predicted steady state acid neutralizing capacity for each iteration and of the aggregate response for 100 iterations enabled comparison of catchment and population levels, respectively. Aggregate and iteration-specific predictions treated on a relative scale all showed similar responses to small to moderate changes in sulphate ion deposition, but differences became apparent when model predictions were viewed on an absolute scale, with the most similar absolute scale predictions for highly variable deposition. Interpretation of multiple model forecasts required rigorous quantitative intermodel comparison, and the proposed approach was generally applicable to computer modelling of environmental processes.

Mapping among model inputs and deterministic results AN - 13720380; 199200598 AB - A set of input mapping rules and algorithms was derived to transform common environmental and chemical information into specific input values for the Integrated Lake Watershed Acidification Study (ILWAS), Model of Acidification of Groundwater in Catchments (MAGIC) and Enhanced Trickle Down (ETD) catchment acidification models to enable direct objective comparison of predictions by accounting for differences in model configurations and eliminating calibration. Application of each model to 2 dissimilar catchments using input mapping yielded ranges of predicted lake acid neutralizing capacity across the models that were within the range obtained from the independent calibration of each model to other comparable catchments and the range of observed interannual variability for 2 natural catchments. The input mapping approach facilitated quantitative comparison of the 3 models which also predicted similar concentrations of sulphate ions, sum of base cations and sum of acid anions.

Similar geochemical conditions were found to prevail. The aquifers were relatively high in clay content and tended to supply single families. Strongly reducing conditions were found but there was no simple correlation with concentrations of iron, manganese or oxygen. A mechanism for mobilization of the arsenic is suggested. Iron oxides were deposited during streamflow while the alluvium was being deposited. The oxides adsorbed dissolved arsenic from the streamwater. Slow groundwater movement affected the buried alluvium. With increasingly reducing redox conditions, the ferric iron was reduced to ferrous iron, thus mobilizing some of the adsorbed arsenic.

To avoid contaminating other wastewaters with hazardous chemicals a method of treating this water was devised based on a combination of an ion-exchange resin and activated carbon. Bench-scale tests using equal proportions of these in a small column confirmed the effectiveness of this method in reducing the concentrations of toxic substances below the limiting values. For application on the shop floor, several cartridges containing either the ion exchange resin or activated carbon were installed on the outside wall of the rinse water tank and the rinse water recirculated continuously through each of the cartridges at about 8 litres per minute. The rinse water in the tank of 1000 litres capacity was thus continuously regenerated, water being added to make up losses due to evaporation, but no water being discharged.

Results provide evidence that US Environmental Protection Agency (EPA) cancer potency estimates are not overly conservative. It is questionable how effective the EPA can be in reducing overall cancer risk from environmental chemicals. It is posited that the only reasonable solution to global pollution is not regulation of emissions, but decreased production through process design, waste reduction, & recycling. 10 References. V.

AN - 80321782; 2088748 AB - Current treatment protocols for exposure to nerve and vesicant agents found in the U.S. stockpile of unitary chemical weapons are summarized, and the toxicities of available antidotes are evaluated. The status of the most promising of the new nerve agent antidotes is reviewed. In the U.S. atropine and pralidoxime compose the only approved antidote regimen for organophosphate nerve agent poisoning. Diazepam may also be used if necessary to control convulsions. To avoid death, administration must occur within minutes of substantial exposure together with immediate decontamination. Continuous observation and repeated administration of antidotes are necessary as symptoms warrant. Available antidotes do not necessarily prevent respiratory failure or incapacitation. The toxicity of the antidotes themselves and the individualized nature of medical care preclude recommending that autoinjectors be distributed to the general public. In addition, precautionary administration of protective drugs to the general population would not be feasible or desirable. No antidote exists for poisoning by the vesicant sulfur mustard (H, HD, HT); effective intervention can only be accomplished by rapid decontamination followed by palliative treatment of symptoms. British anti-Lewisite (BAL) (2,3-dimercapto-1-propanolol) is the antidote of choice for treatment of exposure to Lewisite, another potent vesicant. Experimental water-soluble BAL analogues have been developed that are less toxic than BAL. Treatment protocols for each antidote are summarized in tabular form for use by health care providers.

A review of these studies suggests that turbine-passage mortality of early life stages of fish normally would be relatively low at the low-head, propeller-type turbine installations (e.g., bulb or STRAFLO turbines), for which relevant design information is available. The shear forces and pressure changes in low-head bulb turbines are unlikely to cause ichthyoplankton mortality. Probability of contact with turbine blades is related to size of the fish; less than 5% of entrained ichthyoplankton would be affected. Potential additional sources of mortality related to the design and operation of hydroelectric facilities, and thus mitigable, include withdrawal of deep water and cavitation.

Distinct roles of tyrosine 37 and arginine 41 in receptor binding as determined by site-directed mutagenesis and nuclear magnetic resonance spectroscopy. AN - 80078354; 2172006 AB - Site-directed mutagenesis was employed to examine the function of two highly conserved residues, Tyr-37 and Arg-41, of human EGF (hEGF) in receptor binding. Both a conservative change to phenylalanine and a semi-conservative change to histidine at position 37 yield proteins with receptor affinity similar to wild-type hEGF. A non-conservative change to alanine results in a molecule with about 40% of the receptor affinity, indicating that an aromatic residue is not essential at this position. Both conservative (to lysine) and non-conservative (to alanine) substitutions at position 41 drastically reduced receptor binding to less than 0.5% of the wild-type activity. 1D-NMR data indicate that the replacement of Arg-41 by lysine does not significantly alter the native protein conformation. Thus, Arg-41 may be directly involved in ligand receptor interaction, whereas the side chain of Tyr-37, although possibly important structurally, is not essential for receptor binding.

AN - 79954845; 2389000 AB - A historical cohort mortality study was conducted among 28,008 white male employees who had worked for at least 1 month in Oak Ridge, Tennessee, during World War II. The workers were employed at two plants that were producing enriched uranium and a research and development laboratory. Vital status was ascertained through 1980 for 98.1% of the cohort members and death certificates were obtained for 96.8% of the 11,671 decedents. A modified version of the traditional standardized mortality ratio (SMR) analysis was used to compare the cause-specific mortality experience of the World War II workers with the U.S. white male population. An SMR and a trend statistic were computed for each cause-of-death category for the 30-year interval from 1950 to 1980. The SMR for all causes was 1.11, and there was a significant upward trend of 0.74% per year. The excess mortality was primarily due to lung cancer and diseases of the respiratory system. Poisson regression methods were used to evaluate the influence of duration of employment, facility of employment, socioeconomic status, birth year, period of follow-up, and radiation exposure on cause-specific mortality. Maximum likelihood estimates of the parameters in a main-effects model were obtained to describe the joint effects of these six factors on cause-specific mortality of the World War II workers. We show that these multivariate regression techniques provide a useful extension of conventional SMR analysis and illustrate their effective use in a large occupational cohort study.

AN - 79912996; 2377998 AB - The metabolic interactions of benzene and toluene co-exposure were investigated in male Fischer rats. A closed recirculated exposure system was used to obtain inhalation uptake curves for individual chemicals as well as for a mixture of the two compounds. Pharmacokinetic parameters for benzene and toluene individually were determined in previous experimental studies. These values were incorporated into a physiologically based pharmacokinetic model which simulated the inhalation uptake process for both chemicals simultaneously. An optimal fit to the uptake curves for simultaneous exposure was obtained by adjusting the metabolic interaction terms for each chemical. Mutual suppression of metabolism was apparent. Toluene more effectively inhibited benzene metabolism than the reverse. This simulation approach for analyzing gas uptake data provided a method to determine the metabolic interactions occurring upon inhalation exposure to two different chemicals. Such analyses will prove useful in improving predictive toxicokinetic models.

Criteria for habitat suitability were those identified in freshwater reservoirs (temperature below 25 degree C and dissolved oxygen above 2-3 mg/L), which we confirmed for the York-Pamunkey estuary in the lower bay. Habitat suitability in the upper central basin in July declined significantly from 1962 to 1987, as did juvenile abundance indexes (mean catches per standard seine haul). Thickness of suitable temperature-oxygen habitat correlated significantly with Maryland juvenile indexes the following year. Relative reproductive performance of upper (Maryland) and lower (Virginia) bay stocks changed between 1967-1973 and 1980-1988 in parallel with reduction in upper bay summer habitat. The annual temperature-oxygen cycle in the bay revealed two key areas for striped bass subadults and adults: (1) a zone of cool water in north-central Chesapeake Bay near Annapolis, Maryland, where fish of these ages congregate in summer, and (2) a shallow sill across the lower bay near the mouth of the Rappahannock River, Virginia, where warm surface waters (>25 degree C) in summer impinge on the bottom and may block egress from the bay. The importance of year-round bay residents for reproduction in the upper bay may have been underestimated previously, at least for the recent low population levels. Reduced juvenile production at the head of the bay and population decline would be consistent with limitation of historically important habitat in summer and resultant physiological stresses of high temperature and low dissolved oxygen that affect reproductive competence the following year.

AN - 79896948; 2374557 AB - For some chemicals, induction of presumed dominant lethal mutations has been observed only in female mice and not in males. In those cases, questions arise as to (1) whether the increased embryonic mortality is due to genetic effects of the chemicals in the oocyte or, (2) is caused indirectly through maternal toxicity, and, if genetic, (3) the basis for the sex difference. These questions were studied using the compounds adriamycin and platinol. Neither compound induces dominant lethals in male germ cells, but both increased early embryonic mortality when females were treated prior to mating (treatment of maturing oocytes). Reciprocal zygote transfer experiments ruled out, either entirely or for the large part, maternal toxicity as the cause, and cytogenetic analysis of first-cleavage metaphases revealed high incidences of chromosomal aberrations. The results of both of these experiments thus provide evidence that the early embryonic mortality resulted from genetic effects induced in oocytes. Most interestingly, each compound produced unexpected types of chromosomal aberrations. Adriamycin produced deletions, rings, and presumed chromosome-type rearrangements. Platinol, on the other hand, produced a few chromatid-type aberrations, but the bulk of aberrations were characterized by disorganization of the chromatin, minute fragments, and thread-like chromatin bridges between fragments and chromosomes or between two or more chromosomes. The latter type of cytogenetic damage was observed primarily in the centromeric region. It is hypothesized that the female-specific dominant lethal effects of the two compounds are associated with the diffused state of the maturing oocyte chromosomes.

AN - 79880246; 2196634 AB - Formaldehyde, a widely used industrial chemical to which humans are ubiquitously exposed, presented cause for concern when it was demonstrated to be carcinogenic in laboratory animals. Risk assessment protocols subsequently applied to formaldehyde are of questionable validity in light of the results of recent mechanistic investigations of biological responses to formaldehyde. Further, the hazard of ingested formaldehyde is not addressed in current assessment protocols. This paper addresses the potential human health risks accompanying low-level exposure to formaldehyde as a contaminant in drinking water. In this exposure scenario, noncarcinogenic risk from inhalation of formaldehyde from drinking water is evaluated through knowledge of the metabolism and biological effects of formaldehyde exposure. Noncarcinogenic risk from ingestion of formaldehyde in drinking water is evaluated from the perspective gained by comparison with dietary sources of formaldehyde. Carcinogenic risk to humans is evaluated in light of recent investigations into the mechanisms underlying biological responses to formaldehyde exposure. Finally, based on a comparison of ingestion of formaldehyde in drinking water with ingestion of naturally occurring formaldehyde in foods, a comparative hazard approach to formaldehyde regulation is offered as a supplement to the rigid evaluation protocols currently used.

AN - 79878596; 2371414 AB - Commercial genetic engineering is advancing into areas that require the small-scale introduction of genetically engineered microorganisms (GEMs) to better quantify variables that affect microorganism distribution and survival and to document potential long-term consequences. A recombinant DNA marker system, the lacZY marker, developed by the Monsanto Agricultural Co., enables the distribution and fate of marked fluorescent pseudomonad organisms to be monitored under actual field conditions. Critical evaluation of GEMs under field conditions is imperative if plant-beneficial effects are to be correlated with organism release. This paper evaluates the effectiveness of this marker system and its ability to facilitate the assessment of risks associated with deliberate environmental introductions of genetically engineered microorganisms. Results of prerelease contained growth chamber and field experiments demonstrated that: (1) the scientific risk assessment methodology adopted by Monsanto and approved by the U.S. Environmental Protection Agency was appropriate and comprehensive; (2) the deliberate introduction of a GEM did not pose unacceptable or unforeseen risks to human health or the environment; (3) the lacZY marker is an effective environmental tracking tool; and (4) regulatory oversight should reflect the expected risk and not be excessively burdensome for all GEMs. JF - Regulatory toxicology and pharmacology : RTP AU - Hattemer-Frey, H A AU - Brandt, E J AU - Travis, C C AD - Office of Risk analysis, Health and Safety Research Division, Oak Ridge National Laboratory, Tennessee 37831-6109.

AN - 79878556; 2196635 AB - Absorption refers to the amount of a chemical or substance that is able to cross biological membranes and be taken up by the blood for subsequent distribution to target tissues. The term absorption coefficient, as used here, is a numerical descriptor characterizing that fractional uptake by the blood and represents an approximation of the biological "dose" ultimately responsible for toxicity or other effects following exposure or chemical administration. Regulatory agencies utilize absorption coefficients in deriving acceptable daily intake values and health advisory indices, as well as in quantifying radiological risk. However, absorption coefficients do not exist for many chemicals due to a paucity of appropriate toxicological data. As a result, regulatory policy must often provide default options that assume, for example, 100% absorption by all routes to permit evaluation of "data-gap" chemicals. This paper attempts to improve the situation by providing a discrete source of route-specific absorption coefficients that are based on experimental data reported in the open literature. The estimates presented here are the result of an extensive investigation of three data bases (TOXLINE, HSDB, and CIS), many agency documents, and nearly 200 articles from 30 scientific journals. Acknowledging that absorption efficiency varies with dietary status, age, and several other situation-specific factors, the estimates presented here are intended to reflect absorption by the average adult human.

AN - 79866633; 2367713 AB - In recent pharmacokinetically based risk assessments for methylene chloride, Andersen et al. argued that total reactive metabolite (TRM) divided liver weight was the proper measure of dose to target tissue, while the EPA argued that TRM divided by body weight to the two-thirds power was more appropriate. We demonstrate that the proper tissue metric for a reactive metabolite is dependent upon the mode of deactivation: metabolic or spontaneous. It is argued that the most appropriate measure of tissue dosimetry is: (1) TRM divided by the three-fourths power of body weight if the reactive metabolite is metabolically deactivated; or (2) TRM divided by body weight if the reactive metabolite is spontaneously deactivated.

AN - 79849049; 2364126 AB - We present a statistical test for the hypothesis of independence of two disease processes in animal carcinogenicity experiments. It is assumed that the diseases are occult (detectable only at death via necropsy), and progressive, in that each passes (potentially) through three states in each animal: absent, nonlethally present, and lethally present. The test is based on the combination of statistics from a series of age-stratified 3 x 3 tables in which the animals that die in each age interval are cross-classified into one of these three states for each disease. This test utilizes all the data, whether obtained by sacrifice or by "natural death." It avoids the biases due to lethality noted by Breslow et al. (1974, Journal of the National Cancer Institute 52, 233-239) for the test based on age-stratified 2 x 2 tables, where the nonlethal and lethal occurrences are pooled. In a simulation experiment, we show that such biases (which usually conceal true positive associations and produce spurious negative associations) can be very severe indeed, whereas our test preserves the nominal significance level quite well. The power of the test appears to vary widely, depending on the incidence, time to onset, and rate of progression of each disease. As an example of the application of our method, we assess the association between liver tumors and reticulum cell sarcoma in a radiocarcinogenesis experiment involving approximately 1,000 C3H female mice.

AN - 79770196; 2159890 AB - Three site-directed mutants of human epidermal growth factor, Leu-26----Gly, Leu-47----Ala, and Ile-23----Thr, were examined for their ability to stimulate the protein-tyrosine kinase activity of the epidermal growth factor receptor. The receptor binding affinities of the mutant growth factors were 20- to 50-fold lower, as compared to wild-type growth factor. At saturating concentrations of growth factor, the velocities of the phosphorylation of exogenously added substrate and receptor autophosphorylation were significantly lower with the mutant analogs, suggesting a partial 'uncoupling' of signal transduction. The mutant analogs were shown to compete directly with the binding of wild-type, resulting in a decrease in growth factor-stimulated kinase activity.

The lowest correlation was found using Salmonella mutagenic potency (r = 0.37). The highest correlations were found using the battery of mutation and toxicity data to predict the potency of lung carcinogens (r = 0.94) and liver carcinogens (r = 0.91).

Having participated in some of the first major licensing cases since these changes, we offer observations on how agencies can be more effective in recommending mitigation measures that protect fisheries. Fisheries agencies need access to expertise in fields outside traditional fisheries management to address diverse hydropower impacts. Agencies need effective policies that can be applied to the specific conditions at each project. Coordination and communication between regulatory and resource agencies and with project applicants are important to establish agreement on mitigation recommendations and to share expertise. Agencies will often need to make recommendations on issues for which complete information is not available; if carefully designed, such recommendations can be defensible and conservative. A thorough understanding of current FERC procedures and policies is essential. Many of these same recommendations for effective mitigation are included in the Fish and Wildlife Service's hydropower mitigation policy.

AN - 79691604; 1969412 AB - The active site of ribulose-bisphosphate carboxylase/oxygenase is constituted from domains of adjacent subunits and includes an intersubunit electrostatic interaction between Lys 168 and Glu48, which has been recently identified by x-ray crystallography (Andersson, I., Knight, S., Schneider, G., Lindqvist, Y., Lundqvist, T., Brändén, C.-I., and Lorimer, G.H. (1989) Nature 337, 229-234; Lundqvist, T., and Schneider, G. (1989) J. Biol. Chem. 264, 7078-7083). To examine the structural and functional requirements for this interaction, we have used site-directed mutagenesis to replace Lys168 of the homodimeric enzyme from Rhodospirillum rubrum with arginine, glutamine, or glutamic acid. All three substitutions result in mutant enzymes with less than or equal to 0.1% of wild-type activity. The nonconservative substitution of Lys168 with a glutamyl residue precludes the formation of a stable dimer, explaining the consequential abolition of enzymic activity. Both the Arg168 and Gln168 mutant proteins are isolated as stable dimers, even though the latter obviously lacks an electrostatic interaction present in the wild-type enzyme. Despite the absence of overall carboxylase activity, these two mutant proteins serve as catalysts for the enolization of ribulose bisphosphate, as measured by exchange of the C3 proton with solvent. These observations, as well as ligand-binding properties of the mutant proteins, are consistent with Lys168 facilitating a catalytic step subsequent to enolization.

Biomass determinations, disappearance of TCE from the headspace of spiked soil slurries, and mineralization of [14C]TCE to 14CO2 all showed that microbial activity is greater in rhizosphere soils and that TCE degradation occurs faster in the rhizosphere than in the edaphosphere.

AN - 79748182; 2185506 AB - The occurrence of the munitions compound 2,4,6-trinitrotoluene (TNT) in groundwater and surface water surrounding U.S. Army ammunition plants may result in contamination of local drinking water supplies. TNT exerts its primary toxic effect in humans on the hematologic system and liver, but it is also known to cause gastrointestinal effects and cataracts. Health effects data were analyzed for TNT and although no controlled human studies exist concerning the acute or chronic toxic effects of exposure to TNT, sufficient animal toxicity data are available to derive an ambient water quality criterion for the protection of human health. This paper summarizes the available literature on metabolism and toxicity of TNT in humans and animals. Based on noncarcinogenic mammalian toxicity data, and following the methodologies of the U.S. Environmental Protection Agency, an ambient water quality criterion for the protection of human health of 135 micrograms/liter is proposed when consumption of both contaminated water and fish is anticipated. For drinking water alone, the proposed criterion is 140 micrograms/liter.

The purpose of this brief article is to present these values so that the reader can compare them with the water quality criteria that have been proposed in another article (M. G. Ryon and R. H. Ross, 1990, Regul. Toxicol. Pharmacol. 11, 104-113). In that article, a water quality criterion of 140 micrograms/liter for TNT in drinking water was proposed, and in the present article the methodology by which USEPA calculated a lifetime HA of 2 micrograms/liter is presented.

AN - 79746035; 2185509 AB - The traditional "absolute decision-making" process used by federal regulatory agencies to derive permissible exposure concentrations for hazardous substances is initiated by an evaluation of the "weight-of-evidence" that a substance is a potential human carcinogen. Subsequent conservative procedures applied variably to noncarcinogens and carcinogens yield exposure limits for individual substances based on "data-sparse, model-intensive" techniques which may lack consistency and have difficulty directly addressing the hazards from complex mixtures. This paper describes how a "relative decision-making" technique applicable to complex mixtures can supplement the "absolute" approach currently used. Estimates obtained through this "data-intensive, model-sparse" technique may be evaluated by comparisons to estimates representing a range of hazards "generally regarded as safe" derived through analyses of chlorinated drinking water, cigarette smoke condensate, and other common human exposures. Comparisons are also used to evaluate the relative degree of consistency in risk estimates between 58 suspect human carcinogens analyzed by the U.S. Environmental Protection Agency Carcinogen Assessment Group and by the authors.

AN - 79745991; 2185507 AB - The U.S. Environmental Protection Agency (USEPA) has recently recommended a lifetime health advisory (HA) for hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). The purpose of this brief article is to present the basis for the calculation of the HA so that the reader can compare it with a water quality criterion (WQC) that has been proposed (E. L. Etnier, 1989, Regul. Toxicol. Pharmacol. 9, 147-157). In the earlier article, a water quality criterion of 105 micrograms/liter for RDX in drinking water was proposed, and in the present article the methodology by which USEPA calculated a lifetime HA of 2 micrograms/liter is presented. The differences in the derivation of the WQC and the HA are discussed.

AN - 79716843; 1969910 AB - The past recommendations of the ICRP about dose limits to the skin are reviewed. Recently, an ICRP Task Group has been revisiting the old arguments and setting them against new data. With the exception of the function of cells in the skin associated with immunocompetence, non-stochastic effects have been well characterized and threshold doses are known with a precision appropriate for setting radiation protection standards. The current dose limitations of 0.5 Sv per year and a working lifetime dose limit of 20 Sv should protect the worker population against deterministic effects. When the ICRP made its recommendations in 1977 for dose limits there was no appreciation of the importance of the interaction of ultraviolet radiation (UVR) and X-rays. Both clinical and experimental data show that the risk of ionizing-radiation-induced cancer is significantly increased by subsequent exposures to UVR. Therefore, risks for sun-exposed areas of skin differ from those that are shielded. The risk estimate for skin cancer is very dependent on the selection of the projection model and on the mortality rate assumed. Based on the relative risk model a mortality rate of 0.2 per cent and summing risks for both UVR exposed and shielded skin the risk is about twice (1.94 x 10(-4) Sv-1) that which ICRP derived in 1977. With the absolute model the risk is considerably less, about 0.5 x 10(-4) Sv-1. There is still insufficient understanding of the effects of multiple or protracted exposures on the risk of skin cancer induction. Experimental results suggest that exposures, at least to relatively high total doses, that are protracted over a long period are more carcinogenic than a small number of exposures over a short period.

AN - 79699572; 2320577 AB - Molecular characterization of mutations in the mouse, particularly those involving agent-induced major structural alterations, is proving to be useful for correlating the structure and expression of individual genes with their function in the whole organism. Here we present the characterization of a radiation-induced mutation that simultaneously generated distinct alleles of both the limb deformity (ld) and agouti (a) loci, two developmentally important regions of chromosome 2 normally separated by 20 centimorgans. Cytogenetic analysis revealed that an interstitial segment of chromosome 17 (17B- 17C; or, possibly, 17A2-17B) had been translocated into the distal end of chromosome 2, resulting in a smaller-than-normal chromosome 17 (designated 17del) and a larger form of chromosome 2 (designated 2(17). Additionally, a large interstitial segment of the 2(17) chromosome, immediately adjacent and proximal to the insertion site, did not match bands 2E4-2H1 at corresponding positions on a normal chromosome 2. Molecular analysis detected a DNA rearrangement in which a portion of the ld locus was joined to sequences normally tightly linked to the a locus. This result, along with the genetic and cytogenetic data, suggests that the alleles of ld and a in this radiation-induced mutation, designated ldIn2 and ajIn2, were associated with DNA breaks caused by an inversion of an interstitial segment in the 2(17) chromosome.

AN - 79742579; 2184471 AB - Beliefs about risks associated with two risk agents, AIDS and toxic waste, are modeled using knowledge-based methods and elicited from subjects via interactive computer technology. A concept net is developed to organize subject responses concerning the consequences of the risk agents. It is found that death and adverse personal emotional and sociological consequences are most associated with AIDS. Toxic waste is most associated with environmental problems. These consequence profiles are quite dissimilar, although past work in risk perception would have judged the risk agents as being quite similar. Subjects frequently used causal semantics to represent their beliefs and "% of time" instead of "probability" to represent likelihoods. The news media is the most prevalent source of risk information although experiences of acquaintances appear more credible. The results suggest that "broadly based risk" communication may be ineffective because people differ in their conceptual representation of risk beliefs. In general, the knowledge-based approach to risk perception representation has great potential to increase our understanding of important risk topics.

For each species, the body was divided into five anatomical compartments, consisting of liver, fat, bone marrow, and muscle, and organs such as brain, heart, kidney, and viscera, connected by the arterial and venous blood flow pathways. Metabolism of benzene followed Michaelis-Menten (nonlinear) kinetics in all species and occurred primarily in the liver compartment and, to a lesser extent, in the bone marrow. Comparison of model results with empirical data on inhalation, gavage, and intraperitoneal and subcutaneous injection in mice, rats, and humans, demonstrates the utility of a physiological pharmacokinetic model in describing the pharmacokinetics of benzene in three species across multiple routes of exposure.

AN - 79660630; 2155888 AB - A year-long, multipollutant, indoor air quality study involving 70 occupied houses in four states was completed in 1987. All of the houses included in the study had a partial or complete basement with a concrete slab floor and block walls. On an approximately quarterly schedule, integrating monitors for short-lived Rn progeny, nitrogen dioxide, formaldehyde, and water vapor were exposed for 1 wk in each house on both the basement and main floors. At the beginning of the study, a pair of alpha-track detectors were placed on top of the refrigerator in the kitchen (or some other sampling location on the main floor) and at a location in the basement. One detector at each location was left in place for a year while the other detector was retrieved and replaced once every 3-mo period. In addition, short-term measurements of Rn and 222Rn progeny were made at all sampling locations once per quarter. In this study, comparisons were made between: (1) seasonal and annual averages, (2) summer and winter averages, (3) living-area and basement results, (4) 222Rn and 220Rn progeny, and (5) short- and long-term measurements. The Rn and Rn progeny concentrations in houses near Huntsville, AL were found to be well above recommended action levels (150 Bq m-3). For houses near Birmingham, AL, summer Rn concentrations were found to exceed winter concentrations, whereas for the other houses in the study, winter concentrations exceeded summer concentrations. Potential alpha energy concentrations (PAEC) from 220Rn progeny were found to be generally less than PAEC from 222Rn.

AN - 79766838; 2338826 AB - The purpose of this paper is to use physiologically based pharmacokinetic models to demonstrate that if toxic response is a function of the time profile in physiological time of the concentration of the toxic moiety in the target tissue, then the appropriate interspecies scaling law for toxic compounds which are metabolically deactivated is mg kg-1 per unit of physiological time (mg kg-1 pt-1). At low dose rates this metric is approximately equivalent to mg kg-0.75 day-1. For reactive metabolites which are spontaneously deactivated, an approximate interspecies scaling law is mg kg-1 day-1.

AN - 79636935; 2306364 AB - Forced-air heating and air conditioning (HAC) systems caused an average and maximum increase in air infiltration rates of 1.8- and 4.3-fold, respectively, during brief whole-house studies of tracer gas decay in 39 occupied houses. An average increase in air infiltration rate of 0.33 +/- 0.37 h-1 corresponded to an incremental air leak of 240 m3/h, based on approximate house volume. More detailed tracer gas decay studies were performed in basement, kitchen and bedroom locations of six homes with low air infiltration rates (i.e., less than 0.25 h-1). The HAC mixed the indoor air efficiently between measurement sites. HAC operation also caused 1.1- to 3.6-fold increases in air infiltration rates, corresponding to absolute increases of 0.02 to 0.1 h-1. In an unoccupied research house, three-fold increases in average air infiltration rate with HAC operation (i.e., from 0.13 to 0.36 h-1) were reduced to two-fold (i.e., from 0.10 to 0.18 h-1) by sealing the external HAC unit and crawlspace ductwork system. This sealing also resulted in a 30 percent reduction in crawlspace-to-indoor transport rates with the HAC turned on. Blower door tests indicated a less than 20 percent reduction in house leakage area.

AN - 79628316; 2304907 AB - Eighteen variants recovered from specific locus mutation rate experiments involving the mutagen chlorambucil were subjected to several genetic and molecular analyses. Most mutations were found to be homozygous lethal. Because lethality is often presumptive evidence for multilocus-deletion events, 10 mutations were analyzed by Southern blot analysis with probes at, or closely linked to, several of the specific locus test markers, namely, albino (c), brown (b), and dilute (d). All eight mutations (two c; three b; two d; and one dilute-short ear [Df(d se)]) that arose in post-spermatogonial germ cells were deleted for DNA sequences. No evidence for deletion of two d-se region probes was obtained for the remaining two d mutations that arose in stem-cell spermatogonia. Six of the primary mutants also produced low litter sizes ("semisterility"). Karyotypic analysis has, to date, confirmed the presence of reciprocal translocations in four of the six. The high frequency of deletions and translocations among the mutations induced in post-spermatogonial stages by chlorambucil, combined with its overall high efficiency in inducing mutations in these stages, should make chlorambucil mutagenesis useful for generating experimentally valuable germ-line deletions throughout the mouse genome.

AN - 79610755; 2300582 AB - A refined functional map of a 6- to 11-centimorgan region surrounding the albino (c) locus in mouse chromosome 7 is being generated by N-ethyl-N-nitrosourea (EtNU) "saturation" mutagenesis of stem-cell spermatogonia. In the first phase of an experiment that will eventually test at least 3000 gametes, we screened 972 mutagenized gametes for the induction of both lethal and visible mutations with a two-cross breeding protocol. Thirteen mutations mapping within the limits of a segment corresponding to the cytologically visible Df(c Mod-2 sh-1)26DVT deletion were recovered. They represented three phenotypic groups: prenatal lethality (six mutations); a fitness/runting syndrome (three mutations, provisionally designated as fit variants); and a neurological/balance-defect abnormality (four mutations). Complementation analysis provided evidence for a true repeat mutation at the sh-1 (shaker-1) locus (for the neurological mutations) and another at the here defined fit-1 (fitness-1) locus. In addition, four complementation groups were defined by induced lethal mutations; the two other lethal mutations were each part of a cluster. The recovery of the repeat mutations suggests that the EtNU-induced mutation rate, estimated from specific-locus tests, should make it possible to achieve saturation mutagenesis of a chromosomal region. This experiment is providing basic logistical and statistical information on which to base strategies for expanding the functional map of larger segments of the mouse genome by experimental mutagenesis.

AN - 79534748; 2104836 AB - The potential for altering the specificity of ribulosebisphosphate carboxylase/oxygenase toward gaseous substrates is explored through a modest perturbation of the active site microenvironment. Specifically, replacement of active site Glu-48 with carboxy-methylcysteine is achieved in a two-step process in which the catalytically incompetent Cys-48 mutant protein is first generated and then treated with iodoacetic acid. This regimen of concerted site-directed mutagenesis and chemical modification, effectively lengthening the glutamyl side chain by insertion of a sulfur atom between the beta- and gamma-methylene groups, results in a protein possessing 4-6% of wild-type carboxylase activity. Concomitantly, the engineered enzyme exhibits a specificity factor 5-fold lower than that of wild-type enzyme. This represents the first example of a major change in substrate specificity, albeit in favor of oxygenation, effected by structural alteration of an active site side chain.

Transmitted clastogenic effects of these exposures were measured in terms of induction of dominant lethal mutations and heritable translocations. The concentration-response curves for both endpoints are not linear but are markedly concave upward. Significant increases in dominant lethals were detected at all concentrations, except the lowest one. In comparison, the incidences of heritable translocations were significantly increased at all concentrations.

AN - 80022991; 2209570 AB - A study of meiotic and postmeiotic germ-cell-stage sensitivity of male mice to induction of unscheduled DNA synthesis (UDS) by acrylamide showed that DNA repair could be detected in early spermatocytes (after the last scheduled DNA synthesis) through about mid-spermatid stages. No DNA repair could be detected in later stages. The maximum UDS response was observed 6 hr after i.p. exposure and was about 5 times greater than the response measured immediately after treatment. This is the longest delay between chemical treatment and maximum UDS response yet observed in mouse germ cells. There was a linear relationship between the UDS response and acrylamide exposure from 7.8 to 125 mg/kg. By using 14C-labeled acrylamide it was determined that the temporal pattern of adduct formation in testes DNA paralleled that of the UDS response, with maximum binding occurring 4 to 6 hr after exposure. In contrast, the temporal pattern of adduct formation in liver DNA showed maximum binding within 1 to 2 hr after exposure and was an order of magnitude greater than that found for the testis DNA.

AN - 79602122; 2405387 AB - O6-Methylguanine-DNA methyltransferase (MGMT; DNA-O6-methylguanine:protein-L-cysteine S-methyltransferase, EC 2.1.1.63), a unique DNA repair protein present in most organisms, removes the carcinogenic and mutagenic adduct O6-alkylguanine from DNA by stoichiometrically accepting the alkyl group on a cysteine residue in a suicide reaction. The mammalian protein is highly regulated in both somatic and germ-line cells. In addition, the toxicity of certain alkylating drugs in tumor and normal cells is inversely related to the levels of this protein. The cDNA of the human gene, henceforth named MGMT, has been cloned in an expression vector on the basis of its rescue of a methyltransferase-deficient (ada-) Escherichia coli host. A 22-kDa active methyltransferase encoded entirely by the cDNA contains an amino acid sequence of 61 residues that bears 60-65% similarity with segments of E. coli methyltransferase (products of the ada and ogt genes), which encompass the alkyl-acceptor residues. The human cDNA has no sequence similarity with the ada and ogt genes, due in part to differences in codon usage, and shows no detectable homology with E. coli genomic DNA. However, it hybridizes with distinct restriction fragments of human, mouse, and rat DNAs. The lack of methyltransferase observed in many human cell lines is due to the absence of the MGMT gene or to lack of synthesis and/or stability of its 0.95-kilobase poly(A)+ RNA transcript.

A model by which to evaluate the effectiveness of various protective actions by reconciling the physical protection properties of each with the human responses required to achieve them is presented. This model characterizes the hazard presented by an acutely toxic agent, the human response such accidents engender, & human health effects. Preliminary results indicate that in-place shelter can provide protection against chemical insult in certain circumstances, particularly in emergencies characterized by rapid onset & hazards dominated by peak concentrations. For most people, however, evacuation remains the most effective all-around protective action, particularly for emergencies characterized by slower onset times & hazards dominated by cumulative exposure. Neither evacuation nor expedient sheltering provide adequate protection for rapid onset emergencies involving cumulative exposure hazards. In these instances, some form of mechanical protection is required, eg, respiratory protection or pressurization with charcoal filtration, in combination with evacuation or sheltering.

The theory of back-projection which traced straight ray paths and back-propagation which inverted the wave-equation, is explained. Images were presented for a 2 cm diameter tunnel located at 80 m depth by back-projection, and by back-propagation, buried waste-simulating targets of empty and water-filled metal drums and plastic bags containing styrofoam packing peanuts, a buried water pipe and the skeletal remains of a large sauropod dinosaur buried in sandstone. Objects were successfully located, images of targets with sound speed less than background were comparable in quality to those of sound speed greater than background. Geologic interfaces and soil moisture could be detected and buried targets imaged without sampling directly over the target. The technique could be applied for locating buried waste-sites. Minimal detectable size of a target and level of site complexity at which the technique failed, needed further investigation. Of many potential environmental applications, leak detection from surface or buried hazardous liquid storage facilities, is discussed.

Elevated levels of some anthropogenic radionuclides (caesium-137, caesium-134, cobalt-60 and cobalt-58) were found near the RSNPP during late 1984, the period of sampling. Contamination occurred primarily along streams and in fields irrigated with water from these streams. The irrigation of fish was the single significant pathway to humans identified in this analysis. However, no estimates were made of doses to individuals living around the RSNPP.

Although P. promelas growth ad C. dubia fecundity differed little between sites, survival varied considerably. Multiple regression analyses of toxicity test response variables in relation to the 2 principal component analyses (axis I, associated with hardness-conductivity and axis II, associated with total residual chlorine - TRC) showed that C. dubia survival was linked to axis II but not axis I, while its fecundity was linked significantly to both. Survival and growth in P. promelas were not statistically linked to either axis. TRC was an important regulator of ambient toxicity patterns with C. dubia being more sensitive than P. promelas.

M. saxatilis were inherently more sensitive than B. patronus. Changes in exploitation intensity affected the responses of both populations to the same level. Typical screening-level assessments using surrogate species or QSARs, showed that uncertainties due to life history were negligible compared to those associated with test data. An appendix describes the regression models and assumptions employed in following each of the paths depicted in the flow chart which guided estimation of chronic concentration-response functions from 7 common types of toxicity test data.

Aeration at these dams was analysed statistically, and a commonly-used aeration model, Gameson's equation, compared with a simple linear model. The dissolved oxygen deficit downstream of each dam was modelled as a linear function of the deficit upstream, the water temperature, and the flow rate. When a least-squares parameter estimation method was used to parameterize Gameson's equation, a linear model could reproduce historic aeration measurements as accurately as Gameson's equation, or more accurately where supersaturation occurred.

Mean TCDD concentrations in whole fish and fish fillets from urban areas were low (0.4 and 0.3 pg per g, respectively). Between 59-80 per cent of the fish sampled from background urban sites had TCDD concentrations below detection limits. The data were evaluated using a log probit analysis. The geometric concentration in whole fish from near pulp and paper mills was 10 times higher than the mean concentration of TCDD in whole fish from urban areas but was comparable to mean levels observed in whole Great Lakes fish. The steady state bioconcentration factor for TCDD in fish was estimated as 140,000. The contribution of fish ingestion to total daily intake of TCDD is discussed.

The toxicity of the run-off to young bluegill sunfish (Lepomis macrochirus) during different seasons of the year was investigated. Fish exposed to run-off in springtime and autumn showed greater survival than the controls; this was attributed to the high concentrations of sodium chloride in the run-off at these seasons, which could be detrimental to disease organisms. Higher mortality occurred in fish exposed to winter run-off; this could be due to the high concentrations of zinc and cadmium in this runoff. In view of the considerable dilution of the runoff when it entered the lake, run-off from the bridge would not be toxic to fish in the lake. Such run-off could, however, be toxic to aquatic organisms in smaller waterbodies in winter.

Fish habitats were generally constrained by high temperatures and low dissolved oxygen concentrations. Some possible effects of climatic changes on distributions of stocks of freshwater and coastal striped bass, Morone saxatilis, were predicted. Habitat losses were expected to occur on the northern coast of the Gulf of Mexico and in Florida, in Chesapeake bay and in many freshwater lakes, reservoirs and estuaries.

Exchangeable calcium decreases were attributed to wood accumulation (uptake and sequesting in both living and dead tree biomass). With respect to decreases in exchangeable magnesium, leaching exceeded wood accumulation of magnesium in 3 out of 4 plots (pine, yellow poplar and chestnut oak) but cation leaching in these 3 plots was balanced by sulphate deposition. No conclusion was reached regarding magnesium. The importance of slope position in determining nutrient cycling patterns and long-term changes in nutrient status was also discussed.

Each level involved a high degree of uncertainty. A systematic approach using mathematical and computer models was proposed to clarify the possible extents of change, though precise predictions of climate-associated changes in fish stocks were not attempted. Existing types of mathematical models relating changes in greenhouse gases to environmental conditions and hence to changes in fish stocks are reviewed, with particular attention to ecosystem models, fish physiological process models, and fish population models.

Average total hardness was either less than 80 ppm or more than 200 ppm calcium carbonate. Population variables included age, educational level, alcohol intake, cigarette smoking, dietary fat and dietary calcium. The effects on each of the serum lipids were estimated using an analysis of covariance, with individual variables included as covariates. Serum cholesterol (SC) levels and low density lipoprotein (LDL) cholesterol levels were significantly higher for females in chlorinated communities than non-chlorinated ones. Community SC and LDL levels were also higher for males in chlorinated communities but with smaller differences. High density lipoprotein (HDP) levels were almost identical in both communities for each sex. There are 33 references.

Resting cells removed strontium from dilute aqueous solutions of strontium dichloride at pH 7 with loadings of 25 mg of strontium per g of cell dry weight being achieved by cells exposed to a solution containing 50 ppm (mg per litre) of strontium. Initial binding took less than half an hour and was inhibited in the presence of polyvalent cations but not monovalent cations. The binding activity was localized on the cell envelope and was sensitive to various chemical and physical pretreatments. However it was independent of respiration or other metabolic activity. Strontium appeared to bind to a site that acted as a receptor for calcium in vivo. There was a slow spontaneous release of strontium over time. Bound strontium was displaced by divalent ions, hydrogen ions or various chelating agents. Thus strontium binding by M. luteus was a reversible equilibrium phenomenon.

Following identification of a sharp front using an adaptive mechanism, the element was zoomed, and the hidden fine-mesh nodes were activated. Application of LEZOOM to 4 benchmark problems, representing transport under constant, transient or nonuniform flow conditions with various initial conditions and constant or time-dependent boundary conditions, produced accurate solutions of advection-dispersion problems with Peclet numbers ranging from 0 to infinity, and mesh Courant numbers above 1. Both uniform and nonuniform grid discretization were used. The proposed method eliminated numerical oscillation entirely, and reduced numerical dispersion while resolving difficulties of peak clipping and the effect of grid orientation; even without zooming of any element the LEZOOM approximation was superior to the upstream finite element method. Further research was needed to reduce the number of zoomed elements and to decrease the number of hidden-fine elements per zoomed element. There are 35 references.

The concentrations in the fish decreased with distance from the source of PCB contamination. The mean PCB concentrations in fish caught near the source showed relatively large fluctuations (about 40 per cent) between semi-annual sampling periods, suggesting that these species responded rapidly to changes in PCB concentrations in the water. The results are compared with those reported for other species of fish. Sunfish were not suitable for assessing the possible contamination of other species with PCB, but could be used at specific sites to monitor the effectiveness of remedial measures.

The development of a database allowing documentation of the stability of volatile organics in water so as to increase the pre-analytical holding times and decrease the costs involved was studied. The experimental difficulties encountered in generating relevant data are summarized. These included the need for a large number of identical sample aliquots, the need for a variety of samples matrices, and the requirement that a large number of potential analytes should be present. Ways in which these and related analytical problems were overcome are reviewed.

AN - 13732937; 199101126 AB - The effectiveness of the Superfund programme, initiated by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, is critically examined. The Act required the U.S. EPA to identify hazardous waste sites and facilitate programmes for their remediation, if necessary using federal funds in the clean-up process. The technical feasibility of restoring badly contaminated sites to a sound environmental condition was studied, with particular reference to aquifers. Aquifer restoration was at present technically impossible. The Superfund programme should concentrate on contaminant plume containment and reduction and groundwater protection, recognizing that restoration of aquifers to a pristine condition was not always necessary.

Storm flow was generated from large portions of the catchment as a result of subsurface preferential flow initiated by zones of perched saturation in the soil profile. For most storms, runoff per unit area increased with increasing catchment size, indicating that preferential flow was primarily vertical along relatively deep pathways that emerged in the lower portions of the catchment. However, when antecedent soil moisture was high and rainfall was large, runoff was similar across catchment sizes, indicating that preferential flow was largely lateral along shallow paths (less than 2.5 m deep). Concentrations of some solutes differed for shallow and deep flow paths because dominant sources and sinks were stratified vertically in the catchment.

AN - 79456893; 2616744 AB - The relative potential of high- and low-LET radiation to induce preneoplastic alterations in rat tracheal epithelial cells was evaluated using a combined in vivo-cell culture model. The capacity of X rays and high- and low-dose-rate neutrons to induce preneoplastic changes in isolated rat tracheal epithelial cells and in the intact tissue was compared. The presence of altered populations was determined in culture in terms of the frequency of tracheal epithelial cell populations which exhibit enhanced growth capacity in culture and in terms of the induction of persistent morphological alterations in exposed transplanted tracheas. Prior to assaying for altered cells, tracheal epithelial cells were irradiated as part of the intact tissue or as single cells. Low- and high-LET radiation induced similar maximum frequencies of altered cells when cultures were exposed as single cells, although high-LET radiation was more radiobiologically effective (RBE = 20) than low-LET radiation. The most marked difference between high- and low-LET radiation was observed after irradiation of the intact tissue. Damage induced by low-LET radiation, giving rise to altered populations, was modified in the intact tissue, whereas similar damage induced by high-LET radiation was apparently not.

Overexploitation in fuelwood production results from both open access land use & landholders' high discount rates, with charcoal making undergoing a boom & bust cycle in a specific area, resulting in a shifting spatial pattern of charcoal production & deforestation. Regression analysis indicates that price, household income, family size, use of other fuels, & small-scale commercial activities practiced by households determine residential charcoal use rates. It is concluded that fundamental solutions to Haiti's deforestation lie in changing property rights & reducing poverty, but that more tractable solutions involve the conventional means of charcoal taxation & the introduction of alternative fuels, improved appliances, & reforestation. 6 Tables, 3 Figures.

AN - 79304214; 2683066 AB - This report presents a historical perspective of work done in the U.S. on the metabolism of radionuclides by animals. Also covered are the important concepts of interspecies metabolic correlations and means of accelerating turnover of internally deposited radionuclides. Although a large amount of data exist for a large number of radionuclides and animal species there are many parameters of interest and additional data is needed. Also, much of the data are in internal reports that are not easily accessible. In-depth reviews of work done in the U.S. are not available. If I were asked for recommendations following this workshop, I would propose the formation of a committee to comprehensively review the available data on the metabolism of radionuclides by animals and, if necessary, to plan work that could be conducted by multinational teams of scientists. The results of the planned experiments would remove the remaining uncertainties associated with the uptake, retention and loss of radionuclides by animals that are of economic importance, primarily as food sources, to man. The data would also provide the necessary input to other international efforts related to the calculation of radiation dose per unit intake for members of the general public. These kinds of joint international studies are common in the physical sciences. More are needed in the biological sciences. In addition, this is truly a global problem requiring international collaboration and cooperation. The sharing of the burden would help ensure the collection of the necessary data in a timely and cost effective manner.

AN - 79190773; 2674054 AB - By the late 1950s, the views had evolved that 1) U does not enter cells but damages the kidneys by binding to the luminal membranes of renal tubular cells, interfering with reabsorption of glucose, sodium, amino acids, protein, water, and other substances, and causing slow cell death by suppression of respiration; and 2) U does not cause significant damage to the kidneys at concentrations below 3 micrograms U g-1 kidney. Although there has not been a major unified effort in the past three decades to update the toxicology of U as a nephrotoxin, there have been numerous isolated studies that may be useful in reevaluating these longstanding views on the behavior and action of U in the kidneys and the renal U concentration at which toxic effects may become evident. This paper is a brief review and synthesis of current information on U nephrotoxicity. Much more experimental research and reevaluation of existing data are needed concerning U nephrotoxicity, particularly for the case of chronic exposure.

AN - 79187377; 2777549 AB - Twenty-two nuclear accident dosimetry intercomparison studies utilizing the fast-pulse Health Physics Research Reactor at the Oak Ridge National Laboratory have been conducted since 1965. These studies have provided a total of 62 different organizations a forum for discussion of criticality accident dosimetry, an opportunity to test their neutron and gamma-ray dosimetry systems under a variety of simulated criticality accident conditions, and the experience of comparing results with reference dose values as well as with the measured results obtained by others making measurements under identical conditions. Sixty-nine nuclear accidents (27 with unmoderated neutron energy spectra and 42 with eight different shielded spectra) have been simulated in the studies. Neutron doses were in the 0.2-8.5 Gy range and gamma doses in the 0.1-2.0 Gy range. A total of 2,289 dose measurements (1,311 neutron, 978 gamma) were made during the intercomparisons. The primary methods of neutron dosimetry were activation foils, thermoluminescent dosimeters, and blood sodium activation. The main methods of gamma dose measurement were thermoluminescent dosimeters, radiophotoluminescent glass, and film. About 68% of the neutron measurements met the accuracy guidelines (+/- 25%) and about 52% of the gamma measurements met the accuracy criterion (+/- 20%) for accident dosimetry.

An approaching reality. AN - 79096528; 2746817 AB - A congressional mandate to dispose of the current US stockpile of lethal unitary weapons (Public Law 99-145, Department of Defense Authorization Act of 1986) has international implications and is responsible for a recent major assessment of available disposal alternatives. Eight installations in the continental United States currently host aging stockpiles of chemical warfare agents. The stockpiles are described, the toxicology and physical properties of each agent are characterized, disposal options considered by the US Army are identified, and the role of a programmatic health and environmental assessment in the decision-making process is outlined. Critical findings are that existing community emergency planning and preparedness are inadequate and that communication of risk information requires significant improvement. Measures are under way to address these needs. However, timely disposal of the stockpile entails less of a hazard than continued storage.

AN - 79496360; 2697487 AB - The lack of a reliable quantitative description of blood flow in man has hampered the development of accurate biokinetic models of essential elements, drugs, imaging agents, and carcinogens. In this paper we review and analyse data on blood flow and identify representative percentages of cardiac output and absolute blood flow rates to organs and tissues of man for use as reference values for biokinetic models. To keep the review and analysis to a manageable size we have limited attention to the resting state and have suggested reference values for absolute and relative flow rates only for adult males and females.

AN - 79189709; 2672125 AB - A relative potency method for assessing potential human health effects from exposures to relatively untested chemicals is presented and documented. The need for such a method in evaluating the carcinogenic potential of the chemical warfare agent sulfur mustard (agent HD) from a limited data base is specifically addressed. The best-estimate potency factor for sulfur mustard relative to benzo[a]pyrene is 1.3, with an interquartile range of 0.6 to 2.9. The method is applied to (1) the estimated fence-boundary air concentrations of mustard during operation of a proposed agent incinerator at Aberdeen Proving Ground (APG), Maryland, and (2) the current approved general population exposure level of 1 X 10(-4) mg HD/m3 and the occupational exposure level of 3 X 10(-3) mg HD/m3. Maximum estimates of excess lifetime cancer risk for individuals at sites along the APG boundary range between 3 X 10(-8) and 1 X 10(-7). Lifetime cancer risk estimates less than or equal to 10(-6) are not now regulated by the U.S. Environmental Protection Agency or the Food and Drug Administration. Maximum estimates of excess lifetime cancer risk assuming daily exposure to the approved standards during the proposed 5 years of incinerator operation are on the order of 10(-5) for the general public and 10(-4) for the worker population. These values are considered upper limit estimates.

AN - 79142462; 2761561 AB - Mice received an intraperitoneal injection of 14C-labeled acrylamide (AA) at an exposure of 125 mg/kg to equal that used in genetic studies carried out by Shelby et al. (1986). Subsequently, spermatozoa were recovered from the reproductive tracts of the animals over a 3-week period and assayed for the amount of bound AA. A strong increase in the level of binding occurred in late-spermatid to early-spermatozoa stages; these same stages are also genetically most sensitive to the action of AA. At all time points, alkylation of DNA within the sperm accounted for a very small fraction (generally less than 0.5%) of the total sperm-head alkylation. However, alkylation of protamine, a protein unique to sperm cells, was found to be correlated with total sperm-head alkylation and accounted for essentially all of the AA binding. Two radioactive adducts were found in hydrolysed protamine samples, one of which co-eluted with a standard of S-carboxyethylcysteine. Protamine alkylation appears to be a significant cause of acrylamide-induced genetic damage in spermiogenic cells of the mouse.

AN - 79138666; 2547736 AB - Prior field studies near an old radioactive waste disposal site at Oak Ridge, TN, indicated that following root uptake, metabolism by deciduous trees rendered 99Tc less biogeochemically mobile than expected, based on chemistry of the pertechnetate (TcO-4) anion. Subsequently, the form of technetium (Tc) in maple tree (Acer sp.) sap, leaves, wood and forest leaf litter was characterized using one or more of the following methods: dialysis, physical fractionation, chemical extraction, gel permeation chromatography, enzymatic extraction, or thin layer chromatography (TLC) on silica gel. Chromatography (Sephadex G-25) of TcO-4 incubated in vitro with tree sap showed it to behave similar to TcO-4 anion. When labeled wood and leaf tissues were processed using a tissue homogenizer, 15% and 40%, respectively, of the Tc was solubilized into phosphate buffer. Most (65% to 80%) of the solubilized Tc passing a 0.45-micron filter also passed through an ultrafiltration membrane with a nominal molecular weight cutoff of 10,000 atomic mass units (amu). A majority (72% to 80%) of the Tc in wood could be chemically removed by successive extractions with ethanol, water and weak mineral acid. These same extractants removed only 23% to 31% of the Tc from maple leaves or forest floor leaf litter. Most of the Tc in leaves and leaf litter was removed only by strongly alkaline reagents typically used to release structural polysaccharides (hemicelluloses) from plant tissues. Chromatography (Sephadex G-25) of the ethanol-water extract from wood and the alkaline extract from leaves demonstrated that Tc in these extracts was not principally TcO-4 but was complexed with molecules greater than 1000 amu. Incubations of leaf and wood homogenates with protease approximately doubled the amount of Tc released from contaminated tissues. Ultrafiltration of protease-solubilized Tc from leaves and wood showed that 40% and 93%, respectively, of the Tc was less than 10,000 amu. TLC of the less than 10,000 amu fraction indicated the presence of TcO-4 in wood but not in leaves. In the leaf, TcO-4 is converted to less soluble forms apparently associated with structural components of leaf cell walls. This conversion explains why 99Tc is not easily leached by rainfall from tree foliage and why 99Tc appears to accumulate in forest floor leaf litter layers at the Oak Ridge study site.

AN - 79081149; 2545684 AB - Diverse approaches that include site-directed mutagenesis have indicated a catalytic role of Lys-329 of ribulosebisphosphate carboxylase/oxygenase from Rhodospirillum rubrum. To determine whether Lys-329 is required for the initial enolization of ribulose bisphosphate or for some subsequent step in the overall reaction pathway, the competence of position 329 mutant proteins (devoid of carboxylase activity) in catalyzing exchange of solvent protons with the C-3 proton of substrate has now been examined. Irrespective of the amino acid substitution for Lys-329, the mutant protein retains 2-6% of the wild-type activity in the proton exchange reaction. The complete stability of ribulose bisphosphate during the enolization catalyzed by mutant protein suggests that the major effect of Lys-329 is to facilitate the addition of gaseous substrates (CO2 or O2) to the enediol intermediate. The exchange reaction requires Mg2+, is CO2-dependent, and is inhibited by the transition-state analogue 2-carboxyarabinitol 1,5-bisphosphate. A mutant protein in which Lys-191, the site for carbamylation by CO2 in an obligatory activation step, is replaced by a cysteinyl residue totally lacks proton exchange activity. Barely detectable exchange activity (approximately 0.2% of wild-type) is displayed by the Lys-166----Cys mutant protein, consistent with the previously implicated role of Lys-166 in the deprotonation of ribulose bisphosphate. Retention of exchange activity by the Glu-48----Gln mutant protein, which is slightly active in overall carboxylation, demonstrates that active site Glu-48, like Lys-329, exerts its major effect at some step subsequent to the initial enolization.

AN - 79166026; 2767358 AB - Mice of several strains (A/J, SWR, MaMyJ, BALB/cByJ, 129J, and C57BL/6J) were treated with the carcinogens 3-methylcholanthrene, urethane, and 4-nitroquinoline 1-oxide and then given 1 or 5% glycerol in the drinking water for up to 4 months. Effects of glycerol on lung tumor multiplicity and incidence were evaluated. The effects of glycerol were variable, and in the majority of experiments glycerol failed to enhance tumor development in mouse lung. Analysis of cell kinetics did not show a proliferative response of alveolar or bronchiolar cells to glycerol. In rats, glycerol did not enhance the appearance of putative preneoplastic liver foci, and in C3H mice it did not increase the incidence of spontaneously occurring liver tumors. It is concluded that glycerol does not increase number or incidence of lung tumors in the mouse strains used, whether the animals are pretreated with a carcinogen or not. Glycerol does not affect liver tumor development.

AN - 79104361; 2663782 AB - Metabolic models for U in adults recommended by Wrenn et al. (1985) and the International Commission on Radiological Protection (ICRP 1979a) were used to study the relationship between kidney burden and radiation dose from chronic ingestion of soluble 238U or natural U and whether current radiation standards for the public provide adequate protection against chemical toxicity from U in the kidney. We assumed that the threshold concentration for chemical toxicity is 1 microgram of U g-1 of kidney and that a safety factor of 10 should be applied in limiting kidney burdens for maximally exposed individuals in the general public. We found that a limit on annual effective dose equivalent of 1 mSv (0.1 rem) for chronic exposures of the public from all sources, as recommended by the ICRP (1985) and the National Council on Radiation Protection and Measurements (NCRP 1987), corresponds to concentrations of U in the kidney from chronic ingestion that exceed the assumed threshold for chemical toxicity of 1 microgram g-1 only for 238U using the metabolic model of the ICRP (1979a). However, using either metabolic model (ICRP 1979a; Wrenn et al. 1985), the predicted concentrations of U in the kidney exceeded the limit of 0.1 microgram g-1, based on the assumed safety factor for protection of the public, for both 238U and natural U. From these results, we concluded that chemical toxicity should be considered in developing health protection standards for the public for ingestion of soluble 238U or natural U. Environmental radiation standards for certain practices established by the U.S. Environmental Protection Agency and Nuclear Regulatory Commission (EPA 1987a, 1987b, 1987c, 1987d; NRC 1988a) are consistent with a limit on annual effective dose equivalent of 0.25 mSv (25 mrem) per practice. If the metabolic model of Wrenn et al. (1985) is assumed to be appropriate for chronic ingestion of soluble U in the environment, then the dose limit of 0.25 mSv corresponds to a concentration of 238U or natural U in the kidney that is below the assumed limit of 0.1 microgram g-1 for members of the public. Inhalation of soluble and insoluble U and ingestion of insoluble U were considered. Except for inhalation of soluble U, these modes of intake reduced predicted concentrations in the kidney per unit effective dose equivalent compared with values for ingestion of soluble U. Unresolved issues of importance for determining the significance of chemical toxicity relative to radiation dose in establishing limits on public exposures for U also are discussed.

AN - 79056138; 2734808 AB - With regard to cadmium toxicity, Drosophila strains v;bw and Austin represent extremes in resistance and sensitivity, respectively. Both strains produced metallothionein (MT) in response to Cd ions in their diet. Austin produced more metallothionein than v;bw at Cd ion levels below 0.2 mM, when both strains were allowed lifetime development on Cd2+-containing media. When the rate of MT appearance was measured for 4 days in young adults the results showed no clear trend with time within a strain or between strains. The plot of LC50 vs. MT levels for identical developmental conditions revealed that for v;bw small increases in MT corresponded to large increases in resistance whereas for the sensitive Austin even large increases in MT had comparatively little effect on increasing LC50. Results given here suggest that differences in total MT content do not explain the genetically demonstrable difference in Cd2+-resistance between v;bw and Austin. However, since two MT genes are identified in Drosophila, differences in resistance could be reflective of greater relative amounts of one "more important" MT in the resistant fly.

AN - 78978882; 2720909 AB - A cell culture model was used to assay for the induction of cell populations with enhanced growth capacity in culture in irradiated normal rat tracheal epithelial cells (NTEC). When cultures were maintained in minimally enriched Ham's F-12 plus 5% fetal bovine serum, it was noted that increasing the seeding density from 1 to 100 colony forming units per 60 mm dish decreased the frequency of proliferating epithelial foci (PEF) scored 5-6 weeks after seeding, from 2.5 to 0.07% in controls and from 5 to 0.9% in irradiated cultures. When low density (50 colonies per dish) control cultures were fed medium conditioned by higher density control cultures (300 colonies per dish) the observed frequency of PEF was 10-fold lower than that observed in cultures fed fresh medium or cultures fed medium conditioned by a carcinogen-induced tracheal cell line. These data suggest that some factor(s) present in conditioned medium derived from higher density normal cell cultures inhibits the emergence of many PEF. If cultures are maintained in serum-free enriched Ham's, many (17-21%) PEF were observed in both control and irradiated cultures. Medium harvested from high density cultures maintained in minimally enriched Ham's F-12 (5% FBS) was found to maximally inhibit normal cell thymidine uptake and growth as well as induce cornified envelope formation (terminal differentiation) in proliferating normal cell cultures. Medium harvested from normal cultures maintained in serum-free enriched Ham's was not inhibitory to normal cells and did not induce cornified envelope formation. Subcultured PEF-derived populations and PEF in 4 to 5-week primary cultures also did not produce inhibitor(s). In addition, subcultured PEF-derived cells were not induced to form cornified envelopes in the presence of inhibitory conditioned medium. The data suggest that the elaboration of an inhibitor(s) by normal epithelial cells affects the emergence of PEF. Irradiated cells appear to have some growth advantage over spontaneous PEF in that they are more likely to survive and form PEF under growth conditions associated with higher levels of inhibitor(s) in the medium.

AN - 78959239; 2541940 AB - As rat tracheal epithelial cells progress from a normal to a neoplastic phenotype there are systematic changes in their ability to produce and activate latent transforming growth factor type beta (TGF-beta) as well as systematic changes in their response to this growth factor. Using a TGF-beta radioreceptor binding competition assay it was found that normal proliferating rat tracheal cells in early primary culture produced latent TGF-beta. With the emergence of terminally differentiated cell populations active TGF-beta was also detected in the conditioned medium. When normal cells were cultured under conditions allowing for continued proliferation, no active TGF-beta was detected in the conditioned medium. Colonies of proliferating epithelial cells in 4-6 week primary cultures or subculturable tracheal cell lines did not produce detectable levels of active or latent growth factor. With neoplastic progression there was likewise a change in response to active TGF-beta. Normal tracheal cells in primary culture were highly sensitive to growth-factor-induced decreases in thymidine uptake as well as to the induction of terminal differentiation. Proliferating epithelial cells in late (4-6 week) primary cultures and preneoplastic, subculturable cell lines were often as sensitive as normal cells to the growth factor-induced decline in thymidine uptake. None of these altered populations, however, was induced to differentiate (to form cornified, cross-linked envelopes) in the presence of TGF-beta.

Land elevations were estimated using topographic maps, and flood elevation estimates were based on a dam breach and flood routing model (DAMBRK), among other sources. Various land use and industrial classification categories were used to perform calculations at a disaggregate spatial scale. Depth-damage functions, providing an estimate of damages as a proportion of the existing value of structures, were estimated statistically. Case studies illustrating the method are presented.

The radioactivity in the OETI reached near peak activity by 3 h, and decreased almost 10-fold by 24 h. Most of the activity was associated with parent B[a]P throughout the 95 h. The 3H activity in the surrounding tissue also was mostly associated with B[a]P, but the 3H activity in the liver, kidney, blood and urine was mostly associated with water-soluble plus conjugated metabolites. In the feces, 68% of the 3H activity was in B[a]P at 3 h, but mostly organic as well as water-soluble plus conjugated metabolites were extracted from it throughout the remaining 96 h. Forty-eight hours after insertion of the B[a]P pellets, the feces contained almost 16% of the total 3H activity. Pre-exposure of the OETI to B[a]P for 4 days before insertion of the [3H]B[a]P pellets stimulated metabolism of B[a]P in the tracheas approximately 2-fold, but had no significant effect on the host tissues.

AN - 79020634; 2726748 AB - The chemotherapeutic agent chlorambucil was found to be more effective than x-rays or any chemical investigated to date in inducing high yields of mouse germ-line mutations that appear to be deletions or other structural changes. Induction of mutations involving seven specific loci was studied after exposures of various male germ-cell stages to chlorambucil at 10-25 mg/kg. A total of 60,750 offspring was scored. Mutation rates in spermatogonial stem cells were not significantly increased over control values; this negative result is not attributable to selective elimination of mutant cells. Mutations were, however, clearly induced in treated post-stem-cell stages, among which marked variations in mutational response were found. Maximum yield occurred after exposure of early spermatids, with approximately 1% of all offspring carrying a specific-locus mutation in the 10 mg/kg group. The stage-response pattern for chlorambucil differs from that of all other chemicals investigated to date in the specific-locus test. Thus far, all but one of the tested mutations induced by chlorambucil in post-stem-cell stages have been proved deletions or other structural changes by genetic, cytogenetic, and/or molecular criteria. Deletion mutations have recently been useful for molecular mapping and for structure-function correlations of genomic regions.

AN - 79008170; 2725540 AB - Genetic analyses of certain classes of mutations recovered in the mouse specific-locus test (SLT) have characterized arrays of deletions, overlapping at the marked loci. Complementation maps, generated for several of the regions, have identified a number of functional units surrounding each marked locus and have ordered the mutations into complementation groups. Molecular entry to all but one of the marked regions has been achieved by (1) identifying proviral integrations in, or close to, the specific loci (d, se, a, c); (2) mapping random anonymous clones from appropriately enriched libraries to the longest deleted segments, then submapping to more limited segments on the basis of complementation and deletion-breakpoint maps (c, p); (3) similarly mapping known clones thought to be located in pertinent chromosomal regions (p, c, d); and (4) cloning specific genes that reside in regions corresponding to the deletions (b, c, p). The molecular analyses have confirmed that genetically-inferred deletions are structural deletions of DNA. The emerging physical maps are concordant with the complementation maps, and in several cases have discriminated among members of a complementation group with respect to breakpoint positions. Deletion-breakpoint-fusion fragments have prove to be highly useful for making large chromosomal jumps to facilitate physical mapping. The recent advances toward correlating physical and functional maps of specific regions of the mouse genome owe much to the existence of arrays of mutations involving loci marked in the SLT. In turn, the characterizations of these regions have made it possible to demonstrate qualitative differences among mutations resulting from different treatments. This new capability for qualitative analysis, which will increase as the molecular studies proceed, further enhances the value of the SLT, which has been extensively used for quantitative studies in germ-cell mutagenesis.

AN - 79034312; 2500136 AB - The two active sites of homodimeric ribulose bisphosphate carboxylase/oxygenase from Rhodospirillum rubrum are constituted by interacting domains of adjacent subunits, in which residues from each are required for catalytic activity. Active-site residues include Lys-166 of one domain and Glu-48 of the interacting domain from the adjacent subunit. Whereas all substitutions for Lys-166, introduced by site-directed mutagenesis, abolished catalytic activity, only a negatively charged residue (e.g., aspartic acid) resulted in the disruption of the subunit interactions (Lee et al., 1987). This disruption could result from improper folding of the individual polypeptide chains or to more localized effects (e.g., charge-charge repulsion due to proximal negative charges of Asp-166 and Glu-48 of adjacent domains or conformational changes restricted to a single domain). To address these questions, we have examined the ability of the Asp-166 mutant subunit to associate with a mutant subunit in which the negatively charged Glu-48 has been replaced by the neutral glutaminyl residue. Coexpression in Escherichia coli of the genes for both mutant subunits results in formation of a catalytically active hybrid, despite the absence of activity when either gene is expressed individually. Isolation and characterization of the hybrid show that it is composed of one Asp-166 subunit and one Gln-48 subunit, presumably with only one functional active site per dimeric molecule. This association of dissimilar subunits shows that introduction of a negative charge at position 166 does not lead to overall distortion of subunit conformation. In contrast to the wild-type enzyme, the hybrid dissociates spontaneously at low protein concentration but is stabilized by elevated ionic strengths or by glycerol.

AN - 78961738; 2655037 AB - The occurrence of the munitions compound hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) in groundwater surrounding Army ammunition plants may result in contamination of local drinking water supplies. RDX exerts its primary toxic effect in humans on the central nervous system, but also involves gastrointestinal and renal effects. Symptomatic effects following acute exposure include hyperirritability, nausea, vomiting, generalized epileptiform seizures, and prolonged postictal confusion and amnesia. Health effects data were analyzed for RDX, and although no controlled human studies exist concerning the acute or chronic toxic effects of exposure to RDX, sufficient animal toxicity data are available to derive an ambient water quality criterion for the protection of human health. This paper summarizes the available literature on metabolism of RDX and human and animal toxicity. Based on noncarcinogenic mammalian toxicity data, and following the methodologies of the U.S. Environmental Protection Agency, an ambient water quality criterion for the protection of human health of 103 micrograms/liter is proposed for ingestion of drinking water and aquatic foodstuffs. A criterion of 105 micrograms/liter is proposed for ingestion of drinking water alone.

AN - 78934407; 2930060 AB - The chronic pulmonary toxicity of beryllium sulfate was examined in rats over a 1-yr period after a single, 1-h exposure. Male rats, exposed in a nose-only inhalation chamber to an aerosol of 4.05 micrograms Be/L, were evaluated for lung toxicity by the methods of bronchoalveolar lavage, lung cell kinetics, and histopathologic analysis. Bronchoalveolar lavage activities for alkaline phosphatase (Alk Pase) and acid phosphatase (Ac Pase) were elevated 3 wk after exposure; lactate dehydrogenase (LDH) and Alk Pase activities peaked 3 months after exposure. Histopathologic analysis revealed progressive focal interstitial pneumonitis with a prominent alveolar component of heteromorphic macrophages, neutrophils, and debris. No increase was noted in the overall labeling index in the alveolar cell population at any of the time points sampled. This study demonstrates the effectiveness of bronchoalveolar lavage fluid analysis in monitoring lung damage over a prolonged period and shows that the pulmonary toxicity of beryllium manifests itself as a progressive lesion from a single 1-h inhalation exposure to BeSO4.

(2) Are environmental concentrations around MSW incinerators substantially elevated relative to background levels? And (3) are MSW incinerators the major source of human exposure to PCDDs and PCDFs? Current scientific evidence indicates that (1) combustion sources in general (including steel mills, copper smelting plants, motor vehicles, pulp and paper mills, and MSW incinerators) are major sources of PCDD/PCDF input in the environment; (2) environmental concentrations of PCDDs and PCDFs around operating MSW incinerators are not substantially elevated; and (3) 99% of human exposure to PCDDs and PCDFs is from background contamination, even for individuals living near a modern MSW incinerator.

AN - 78875533; 2564040 AB - Most estimates of the radiation dose lethal to 50 per cent of a human population are based on historical data taken from well-known experiences reflecting inadequately known physical and biological conditions, or from medical procedures where individual patients received advantages of modern clinical care. It has been debated as to whether the experience of unprotected man would more closely reflect that of hospital patients or of the radiobiological studies with large animals. The issue at question is whether the apparent two-fold or more increased susceptibility of large animals to death from bone marrow damage (compared with the majority of estimates for man) is due more to true interspecies differences or the lack of medical support. This study is an attempt to assess the radiosensitivity of unprotected man in terms of the composite animal experiments. Based upon an extensive data base containing 121 separate animals studies using 13 different species, an estimate of the mortality dose-response relationship due to a uniform, continuous field of photon radiation is predicted for 70 kg unprotected man. Man is assumed to have a level of radiation sensitivity similar to that of the species represented in the data base, after adjustment for body weight. The mathematical model used includes fixed terms to account for effects of body weight and dose rate, and random terms reflecting inter- and intra-species variation and experimental error. Point predictions and 95 per cent prediction intervals are given for the LD05, LD10, LD25, LD50, LD75, LD90, and LD95, for dose rates ranging from 0.01 to 0.5 Gy/min, and treatment times ranging from about 2 min to about 24 h. At 1 cGy/min our point prediction of the LD50 is 299 cGy with an associated 95 per cent prediction interval of (168 cGy, 535 cGy). The analogous values at 50 cGy/min are 183 cGy and (103 cGy, 326 cGy).

AN - 78860604; 2493448 AB - Oligodeoxynucleotide-mediated mutagenesis of the ada gene of Escherichia coli was used to produce two mutant Ada proteins. In mutant I the methyl acceptor Cys-321 for O6-methylguanine was replaced by histidine; and in mutant II the positions of Cys-321 and His-322 of the wild-type protein were inverted. Neither mutant protein had O6-methylguanine-DNA methyltransferase activity, but both retained the phosphotriester-DNA methyltransferase activity involving methyl group transfer to Cys-69. Under the control of the endogenous promoter, synthesis of mutant I protein was undetectable before or after adaptation treatment with promoter, synthesis of mutant I protein was undetectable before or after adaptation treatment with N-methyl-N'-nitro-N-nitrosoguanidine. This appeared to be due to both inhibition of transcription of the mutant gene and degradation of the synthesized protein. On the other hand, mutant II protein was inducible by N-methyl-N'-nitro-N-nitrosoguanidine, although to a smaller extent than the wild-type protein was, and the phosphotriester-DNA methyltransferase activity appeared to reside in 24- to 30-kilodalton cleavage products. Mutant I protein could be produced under lac promoter control, and its cleavage products, unlike those of mutant II protein, tended to aggregate. These results indicate that (i) Cys-321 cannot be replaced or transposed with the nucleophilic amino acid histidine for O6-methylguanine-DNA methyltransferase function, (ii) single amino acid replacement or transposition at the O6-methylguanine methyl acceptor site can have a profound effect on the in vivo stability and regulatory function of the Ada protein, and (iii) the integrity of the protein may not be absolutely needed for its transcription-activation function.

AN - 78838155; 2911257 AB - The mouse egg is ovulated with its nucleus arrested at the metaphase-II stage of meiosis. Sperm entry triggers the completion of the second meiotic division. It has been speculated that damage to the meiotic spindle of normally ovulated eggs at around the time of sperm entry could result in chromosome malsegregation and the death of conceptuses with numerical chromosome anomalies. This hypothesis was tested using nocodazole, a microtubule inhibitor. Nocodazole was administered either to maturing preovulatory oocytes or to normally ovulated eggs at one of the following stages: (1) the time of sperm entry, (2) early pronuclear stage, (3) pronuclear DNA synthesis, (4) prior to first cleavage division, (5) early 2-cell stage, or (6) prior to the second cleavage division. Little or no effect was observed for treatment times other than the time of sperm entry, when the egg is being activated to complete the second meiotic division. Remarkably high frequencies of embryonic lethality, expressed at around the time of implantation, were induced at this stage. Cytogenetic analysis of first cleavage metaphases of zygotes treated at the time of sperm entry revealed a high incidence of varied numerical chromosome anomalies, with changes in ploidy being predominant.

AN - 78822800; 2911260 AB - Earlier studies in this laboratory revealed that ethylene oxide (EtO) or ethyl methanesulfonate (EMS) induced high frequencies of midgestation and late fetal deaths, and of malformations among some of the surviving fetuses, when female mice were exposed at the time of fertilization of their eggs or during the early pronuclear stage of the zygote. Effects of the two mutagens are virtually identical. Thus, in investigating the mechanisms responsible for the dramatic effects in the early pronuclear zygotes, the two compounds were used interchangeably in the experiments. First, a reciprocal zygote-transfer study was conducted in order to determine whether the effect is directly on the zygotes or indirectly through maternal toxicity. And second, cytogenetic analyses of pronuclear metaphases, early cleavage embryos, and midgestation fetuses were carried out. The zygote transplantation experiment rules out maternal toxicity as a factor in the fetal maldevelopment. Together with the strict stage specificity observed in the earlier studies, this result points to a genetic cause for the abnormalities. However, the cytogenetic studies failed to show structural or numerical chromosome aberrations. Since intragenic base changes and deletions may also be ruled out, it appears that the lesions in question induced in zygotes by the two mutagens are different from conventional ones and, therefore, could be a novel one in experimental mammalian mutagenesis. Alternatively, the mechanism could involve a non-mutational 'imprinting' process that caused changes in gene expression.

AN - 79413654; 2691448 AB - Our previous attempts to predict the toxicities of 24 metal ions for a given species, using physicochemical parameters associated with the ions, are summarized. In our current attempt we have chosen indicators of toxicity for biological systems of increasing levels of complexity--starting with individual biological molecules and ascending to mice as representative of higher-order animals. The numerical values for these indicators have been normalized to a scale of 100 for Mg2+ (essentially nontoxic) and 0 for Cd2+ (very toxic). To give predicted toxicities to humans, extrapolations across biological species have been made for each of the metal ions considered. The predicted values are then compared with threshold limit values (TLV) from the literature. Both methods for predicting toxicities have their advantages and disadvantages, and both have limited success for metal ions. However, the second approach suggests that the TLV for Cu2+ should be lower than that currently recommended.

AN - 79330312; 2684657 AB - Means to assess the toxicity of wastewaters are essential to implementing the Federal Clean Water Act. Health risk assessment based on single chemicals is limited by the number of chemicals that can be identified and to those chemicals for which toxicity data are available. Long-term whole animal tests on large numbers of wastewater samples are not practical. In this study, two short-term tests, the Salmonella mutagenicity assay and the Chinese hamster ovary (CHO) cell assay for mutagenicity and cytotoxicity, were evaluated as potentially useful biomonitors of wastewaters. Standard assay protocols were modified to allow testing of up to 2.5 and 3.4 ml of unconcentrated water in the bacterial and mammalian cell tests, respectively. Cytotoxicity and mutagenicity were detected in some unconcentrated wastewater samples using these modifications. Data on eight wastewater samples, representing five different sites, indicated that the Salmonella test is the more sensitive indicator of mutagenic activity in those samples, whereas the CHO test is a sensitive indicator of the presence of cytotoxic components. Wastewater concentrates, prepared by adsorption onto XAD-2 and "blue cotton," were compared in the two bioassays. In a single concentrate, the two short-term tests detected distinctly different mutagens. Advantages of using the CHO-AS52 cell line instead of the CHO-K1BH4 line for detecting wastewater mutagens were indicated. This study illustrates the complementary use of multiple bioassays and concentration methods to detect and characterize toxic components in wastewater.

AN - 79036180; 2659327 AB - The scientific foundations for several mammalian germ-line mutagenesis tests in common use today were laid in the 1930s, 1940s, and early 1950s. Subsequent developments in the field have had multiple objectives: detection of mutagenicity of environmental agents (which has led to the development of numerous methodologies), identification of biological and physical factors that affect mutation yield, analysis of the structural nature of the genetic alterations, and assessment of the organismic effects of various types of mutations. Mutagenesis studies have made numerous contributions to basic genetics by generating mutant types that led to elucidation of sex-determining mechanisms in mammals; formulation of the single-active-, or inactive-, X-chromosome hypothesis; correlation of genetic and cytological maps; discovery of genetic "imprinting" phenomena; study of developmental pathways and cell lineages, etc. Particularly useful are sets of complexly overlapping deletions that have been recovered in radiation mutagenesis studies, propagated in breeding stocks, and genetically analyzed; these have constituted prerequisites for molecular genetic studies aimed at development of the DNA structure-function relationships for important genomic regions. Mutagenesis experiments have also served to identify mutagens that are particularly effective in inducing specific types of genetic lesions desired for basic studies. Reciprocally, basic genetics has contributed to the development of mutagenesis tests and has enhanced the value of the specific-locus test by adding to its quantitative capabilities the capability for qualitatively characterizing the actions of mutagens.

AN - 78837116; 2492497 AB - The REV1 gene of Saccharomyces cerevisiae is required for normal induction of mutations by physical and chemical agents. We have determined the sequence of a 3,485-base-pair segment of DNA that complements the rev1-1 mutant. Gene disruption was used to confirm that this DNA contained the REV1 gene. The sequenced segment contains a single long open reading frame, which can encode a polypeptide of 985 amino acid residues. The REV1 transcript is 3.1 kilobase pairs in length. Frameshift mutations introduced into the open reading frame yielded a Rev-phenotype. A base substitution, encoding Gly-193 to Arg-193, was found in this open reading frame in rev1-1. Deletion mutants, lacking segments of the 5' region of REV1, had intermediate mutability relative to REV1 and rev1-1; a complete deletion exhibited lower mutability than rev1-1. REV1 is not an essential gene. An in-frame fusion of the 5' end of the REV1 open reading frame to the lacZ gene produced beta-galactosidase activity constitutively. The predicted REV1 protein is hydrophilic, with a predicted pI of 9.82. No homologies to RAD1, RAD2, RAD3, RAD7, or RAD10 proteins were noted.

It provides 17% of the world's electricity today -- almost 20% in the U.S. Reducing the emissions of carbon dioxide over the next 30 to 50 years sufficiently to address the issue of global warming can only be accomplished by a combination of much improved energy efficiency, substantial growth in use of nuclear power, and substantial growth in use of renewable energy. This paper discusses new initiatives in the major nuclear technologies (LWR, HTGR, LMR) which are emerging from a fundamental reexamination of nuclear power in response to the challenges and opportunities in the 21st century. To fulfill its role, nuclear power must gain worldwide acceptance as a viable energy option. The use of modern technology and "passive" safety features in next-generation nuclear power plants offers the potential to simplify their design and operation, enhance their safety, and reduce the cost of electricity. With such improvements, we believe nuclear power can regain public confidence and make a significant contribution to our energy future.

Manganese, cobalt, cerium, europium and uranium were associated with colloidal material in groundwater. Colloid-mediated transport of contaminants was possible if contaminants associated strongly with particles, dissolved organic carbon level were high, aquifers were porous or fractured, or if aqueous chemistry was dominated by sodium.

These bags allowed larger volumes of sample or spike solution to be prepared to a high degree of homogeneity while using less methanol. The accuracy was generally plus or minus 20 per cent or better. In water samples most of the volatile organics were stable at refrigerator temperature for 14 d, a time sufficient to allow distribution and analysis. As the stability of the samples was verified it should become possible to carry out interlaboratory performance studies over long periods of time.

N1 - Last updated - 2011-12-12 ER - TY - JOUR T1 - Liquid chromatographic determination of total formaldehyde in drinking water AN - 13755854; 199001735 AB - Formaldehyde was determined in hot and cold water samples from 12 one-storey and 22 two-storey houses equipped with poly(acetal) plumbing fixtures. These fixtures (elbows and tees) could be hydrolysed with a resultant leaching of formaldehyde into the domestic water supply. The analytical method involved derivatization of the formaldehyde present in 1 litre samples with 2,4-dinitrophenylhydrazine (DNPH) in strong acid (2M) medium, extraction with chloroform, exchange of solvent from chloroform to methanol and separation and quantitation using reversed-phase liquid chromatography with UV detection (365 mm). Action thresholds of 20 ug per litre were routinely found with formaldehyde recovery typically exceeding 90 per cent at 20-200 ug per litre. Formaldehyde was found at levels above the reporting limit (20 ug per litre) in 80 per cent of hot and cold water samples from one-storey dwellings but in less than 50 per cent of those from two-storey dwellings. Concentrations were greater in hot than in cold water.

The results suggested that inputs from oceanic sources greatly exceeded inputs from river-borne or drainage-basin sources as far as 30 km upstream. The principal mechanisms for removing dissolved plutonium and lead-210 from sea water and concentrating these radionuclides in estuarine areas was resuspension of sediment in dynamic coastal areas, sorption on fine particles, and landward transport of particulate matter along the bottom. These findings implications for the disposal of chemically reactive substances in coastal waters. There are 38 references.

The extent to which the presence of male C. dubia could confuse the interpretation of a 7-d Ceriodaphnia test's fecundity endpoint was investigated in ambient stream waters. Four out of 5 tests contained an unusually large proportion of males (9.6-38.8 per cent). The sensitivities of males and females to cadmium and phenol were compared. In both cases males died more quickly than the females. The statistical implications of the presence of males and gender specific sensitivity are discussed.

Tabulated and graphical data are presented from a study on the distribution of total PCB in the lake water sediment. Analysis of sediment cores showed that, although the highest concentrations of PCB had now been buried, considerable amounts were also present in the upper layers of sediment. The greatest amounts were found closest to the point source of the pollution and concentrations decreased with distance downstream. The effects of dredging and the flushing of sediment accumulated behind small power-generation dams upstream on the polluted tributary, are discussed briefly.

AN - 78669865; 3228718 AB - That certain environmental chemicals can induce transmissible mutations in germ cells of experimental mammal is clear. The assumption that under certain conditions these chemicals are also likely to be mutagenic to human germ cells is not detectable. However, it is a difficult challenge to determine the level of human exposure at which such chemicals can be produced and used economically without significantly harming human health. Data on transmitted genetic effects in mice are necessary, not only as a measure of endpoints that are considered directly in genetic risk assessment, but also as the standard for evaluating the usefulness of non-germ-cell effects as predictors in genetic risk assessment. To carry out a "real world" genetic risk assessment exercise, in vivo mouse data are being obtained for two model chemicals--ethylene oxide and acrylamide. Both chemicals are capable of inducing transmissible genetic effects in mice; their production and use involve measurable human exposures; and, because they are socially and economically important, they are not likely to be banned altogether despite their mutagenicity. For both chemicals, data are not sufficient for accurate low-dose and low-dose-rate extrapolations.

AN - 78555400; 3194417 AB - Mouse zygotes containing one multiple-recessive parental genome (a, b; p cch; d se; s) and the corresponding wild-type alleles in the other were exposed to N-ethyl-N-nitrosourea (ENU) at various stages in vivo. At weaning age, the resulting mice were examined for mutations at the marked loci as well as at others producing externally visible phenotypes. Because of viability problems in one of two reciprocal crosses, the bulk of the mutagenesis data are derived from the cross that detects recessive mutations in the maternal genome. The mutation rate was approximately 8 times higher in groups treated 2.5-3 hr postmating (sperm entry, completion of second meiotic division) than in those injected 5-6 hr postmating (pronuclear formation). In the former more sensitive zygote population, the mutation rate is about an order of magnitude greater than that induced by the same ENU exposure (50 mg/kg) to spermatogonial stem cells. Of 11 mutants recovered, 8 were mosaics. Progeny tests have demonstrated germ-line involvement for most of the mosaics, and the average fraction of the germ line carrying the mutation is close to 50%. The nature of the mutations indicates (i) that the mosaicism results not from misassortment at the first cleavage but from mutation affecting one DNA strand of the maternal chromosome, and (ii) that the mutations are intragenic lesions rather than multilocus deletions, thus resembling ENU-induced mutations in spermatogonia. The finding that mosaicism for presumed point mutations is readily inducible by ENU treatment of zygotes may provide a means of generating genetic materials that can be of use for developmental studies.

AN - 78626406; 3214429 AB - Microcrystalline cellulose (10 mg of Avicel/ml) was hydrolysed to glucose by different concentrations of the purified cellulase components endoglucanase (EG) II and cellobiohydrolases (CBH) I and II, alone and in combination with each other, in the presence of excess beta-glucosidase. At a concentration of 360 micrograms/ml (160 micrograms of EG II/ml, 100 micrograms of CBH I/ml and 100 micrograms of CBH II/ml) the degree of synergism among them was negligible. As the concentration of cellulase decreased, the degree of synergism increased, reaching an optimum at 20 micrograms/ml (5 micrograms of EG II/ml, 10 micrograms of CBH I/ml and 5 micrograms of CBH II/ml). There was no apparent relationship between the ratio of the components and the degree of synergism. The latter is probably due, though it could not be proved, to the level of saturation of the substrate with each component. Inhibition of Avicel hydrolysis was observed when the substrate was incubated with saturating and nonsaturating concentrations of a mixture of EG II and CBH I respectively. A similar result was also observed with a combination of EG I and EG II.

AN - 78556644; 3193982 AB - The effect of ethylene oxide (EtO) inhalation-exposure rate on the induction of DNA breakage in late spermatids and on unscheduled DNA synthesis (UDS) in early spermatids was studied. The exposures were 450 parts per million (ppm) for 4 h, 900 ppm for 2 h, and 1800 ppm for 1 h. Thus, the total exposure was always 1800 ppm-h. Both DNA breakage and UDS were found to increase by a factor of approximately 3 in going from the low to high EtO concentration, suggesting that the molecular dose of EtO to the testis had increased by a similar factor.

AN - 78513913; 2460698 AB - Two monoclonal antibodies (MoAb) have been isolated from two different F344 rats immunized with normal BALB/c mouse lung homogenates. The MoAbs 273-34A and 411-201B demonstrate similar staining properties when used in immunohistochemistry and have been shown to bind to endothelial cells in the lung using immunogold electron microscopy. Radiolabeled MoAb 273-34A injected intravenously localizes rapidly to lung. Ratios of MoAb to control and values for percentage of recovered dose/gram are 50-fold higher in lung than in other organs. Both MoAbs recognize the same 112 kilodalton protein (P112) on the surface of lung cells in culture but do not compete for binding with each other. Both antibodies can be used to purify P112 from normal mouse lung homogenate using immunoaffinity chromatography. These MoAb have been used in a two-site, quantitative assay for P112. Data show that normal lung contains high amounts of P112 (500 to 700 ng/mg P), whereas other organs have low (spleen, uterus) or undetectable (liver) levels of P112. We conclude that endothelial cells in different organs are not identical and that P112 is preferentially expressed in lung endothelial cells. Quantitation of P112 may be useful to assess the role of endothelial cells in toxic injury, lung diseases, and growth and vascularization of lung tumors.

AN - 78498649; 3182279 AB - A Monte Carlo computer code (OREC) for calculating the detailed transport and energy deposition for primary electrons and all of their secondaries in liquid water has been investigated for use in beta-ray dosimetry. Some modifications have been made in the original code for its application to tissue and tissue-equivalent materials. The code gives reasonably good agreement with beta spectral data and depth-dose curves measured in tissue-equivalent plastics for several calibrated beta sources. The calculations permit a direct evaluation of the skin dose equivalent, i.e., the dose equivalent, Hs (0.07), at a depth of 0.070 mm in tissue. Calculations are presented for monoenergetic electrons, showing the distributions in the maximum depth of penetration and in the total pathlength traveled. Direct comparisons are made between depth-dose curves calculated for 99Tc and 147Pm plaque sources and measurements made with extrapolation chambers. The energy spectrum of beta particles emerging from a thick 99Tc plaque source also is calculated, and the angular distribution is found to be almost independent of the energy. The pulse-height spectrum in a tissue-equivalent plastic scintillator calculated for this source shows good agreement with the measured spectrum. The calculations also provide the Hs(0.07) dose equivalent for the 99Tc source, which is found to be consistent with that inferred independently from the spectral measurements. A calculated curve for converting spectrometer measurements to Hs(0.07) dose equivalent is in good agreement with a semi-empirical curve that was developed independently. It appears that calculations made with the electron transport code for water can provide useful information for beta dosimetry.

AN - 78520091; 3188020 AB - Adult BALB/c mice, which are sensitive to hyperoxia (LT50 = 4.5 days 100% O2), were made tolerant to 100% O2 after treatment with butylated hydroxytoluene (BHT). Following a single ip dose of 400 mg/kg, mice survived longer periods in O2 when exposed to O2 at 7, 14, and 21, but not 2 days, following BHT injection. The tolerance was most pronounced on Day 7 (LT50 = 9.6 days) and decreased with time (LT50 7.7 days on Day 14 and 7.3 days on Day 21). Glucose-6-phosphate dehydrogenase levels of whole lung homogenates following BHT exposure were elevated on Day 7 when expressed as per milligram of protein or DNA. Other antioxidant defenses were generally increased only when expressed on a per lung basis. Histopathology of lungs from BHT-treated mice revealed typical BHT-induced lung lesions. BHT treatment followed by long-term hyperoxic exposure produced additional damage to the lung manifested by the exudative phase of diffuse alveolar damage with 1 week of exposure. This was followed by the proliferative phase, then chronic interstitial pneumonitis and fibrosis with 2 and 6 weeks of exposure, respectively. Mice continued to survive in 100% O2 despite this damage. We conclude that pretreatment with BHT enhances O2 tolerance in mice, which may be mediated by induction of antioxidant defenses and also by cell renewal induced by BHT damage.

AN - 78475085; 3176033 AB - The single and combined effects of 2 environmental carcinogens, benzo[a]pyrene (BAP) and formaldehyde (HCHO), on cell growth and DNA damage were assessed in a rat tracheal epithelial cell line, C18. Treatment of C18 cells with HCHO for 90 min reduced the calculated growth index at the highest concentration tested, 400 microM, while no growth effects were observed with BAP treatments. Combination treatments reduced the growth index to 75% of control values. Alkaline elution analysis of C18 cell DNA detected both DNA-protein crosslinks (DPC) and single-strand breaks (SSB) as a result of HCHO treatment, while BAP caused only SSB. HCHO-induced SSB were repaired within 2 h, whereas BAP-induced SSB persisted for at least 48 h. Combination treatment of cells with BAP followed by HCHO enhanced the number of SSB, but reduced DPC. The results are discussed in reference to earlier work which demonstrated the interaction in vivo between BAP and HCHO with respect to their carcinogenicity in rat tracheal implants.

AN - 78386872; 3045117 AB - A synthetic chimeric gene, coding for the human epidermal growth factor fused to the signal peptide of Escherichia coli alkaline phosphatase, was cloned into E. coli under the transcriptional control of the trp-lac (tac) promoter. Following induction with isopropylthiogalactoside, the secretion of the correctly processed protein product into the bacterial periplasm was detected and quantitated by its specific binding to the epidermal growth factor receptor. The purified protein was identical to authentic human epidermal growth factor in size, amino acid composition, primary sequence, receptor binding, and stimulation of receptor protein-tyrosine kinase activity. Based on interspecies homologies, structural considerations, and reported studies with peptide fragments, structure-function analysis was initiated with alterations of targeted amino acid residues by oligonucleotide-directed mutagenesis. The receptor binding affinity of each mutant, relative to the wild type, was measured by both radioreceptor competition and receptor tyrosine kinase stimulation assays. In general, the values obtained by the two methods were in agreement for each species of epidermal growth factor and followed the order: wild type greater than Glu24----Gly greater than Asp27----Gly much greater than Pro7----Thr greater than Tyr29----Gly greater than Leu47----His. The relatively low values obtained with the last two mutants suggest that Tyr29 and Leu47 may be important for the biological activity of human epidermal growth factor.

AN - 78485611; 3180031 AB - The DNA damage associated with benzo(a)pyrene (B[a]P) and formaldehyde (HCHO) exposure in rat tracheal implants was determined by alkaline filter elution adapted to measure DNA-protein cross-links (DPC) in vivo. In addition, histopathological responses of the tracheal epithelium were quantitated after multiple exposures to 20 micrograms B[a]P and 0.2% HCHO. Compared to either agent alone, combined exposure for 1-4 weeks caused an increase in cellular atypia and greater thickness of hyperplastic and metaplastic lesions. HCHO exposure resulted in a dose-dependent increase in DPC with a maximal response of 85% DNA filter retention at 0.2% HCHO, which were mostly removed by 72 h. B[a]P did not cause DPC, but when tracheas were pre-exposed to 20 micrograms B[a]P followed by 0.05% HCHO there was a 15% decrease in HCHO-induced DPC. This competition between B[a]P and HCHO for sites presumably on DNA does not offer a clear explanation for their markedly enhanced cocarcinogenicity observed in previous studies, but does demonstrate the interaction between the two agents in tracheal epithelium.

AN - 78445027; 3170209 AB - To provide an opportunity for dosimetrists to test and calibrate their neutron personnel monitoring systems, the staff of the Dosimetry Applications Research (DOSAR) Facility at the Oak Ridge National Laboratory (ORNL) has conducted personnel dosimetry intercomparison studies (PDIS) periodically since 1974. During these studies, personnel dosimeters are mailed to ORNL, exposed to low-level (less than 15 mSv) neutron dose equivalents in a variety of mixed-radiation fields, and then returned to the participants for evaluation. These intercomparisons have provided more data on neutron dosimeter performance than any other periodic test program conducted to date. This report presents a summary and analysis of about 3450 neutron dose equivalent measurements reported for PDIS 7 through 12 (1981-1986) with emphasis on low dose equivalent sensitivity, accuracy and precision, and performance relative to accreditation standards for the basic types of personnel dosimetry systems.

AN - 78395745; 3410691 AB - The quality factor, Q, is a dimensionless modifier used in converting absorbed dose, expressed in gray (or rad), to dose equivalent, expressed in sievert (or rem). The dose equivalent is used in radiation protection to account for the biological effectiveness of different kinds of radiation. The quality factor is related to both linear energy transfer (LET) and relative biological effectiveness (RBE). The RBE obtained from biological experiments depends in a complex way on the observed biological effect, the specific test organism and the experimental conditions. Judgment is involved, therefore, in the choice of Q. Questions regarding the adequacy of current Q values for neutrons were first raised in a 1980 statement by the National Council on Radiation Protection and Measurements (NCRP) and later in a 1985 statement by the International Commission on Radiological Protection (ICRP). In 1980, the NCRP alerted the technical community to the possibility of a future increase between a factor of 3 to 10 in the Q for neutrons, and in 1985, the ICRP suggested an increase by a factor of 2 in Q for fast neutrons. Both these advisory groups are now recommending essentially the same guidance with regard to Q for neutrons: an increase by a factor of 2. The Q for neutrons is based on a large, albeit unfocused, body of experimental data. In spite of the lack of focus, the data supporting a change in the neutron quality factor are substantial. However, the proposed doubling of Q for neutrons is clouded by other issues regarding its application. These issues are discussed, together with the current database for the neutron quality factor. Improvements are needed to provide better guidance with regard to both Q for neutrons and its application in radiation protection.

AN - 78395663; 3410717 AB - The accuracy of an environmental transport model is best determined by comparing model predictions with environmental measurements made under conditions similar to those assumed by the model, a process commonly referred to as model validation. Over the past several years, we have done a variety of validation studies with the popular Gaussian plume atmospheric dispersion model using data from tests conducted on the Hanford site. Data for short-term releases of small particles for a range of release heights from surface level to 111 m have been used. Downwind distances examined have ranged from a few hundred meters to 12.8 km, depending on the particular data used. Measured and predicted ground-level centerline, crosswind-integrated, and 22.5 degrees sector-averaged air concentrations have been compared. Up to six different sets of atmospheric dispersion parameters and three different atmospheric stability class specification schemes have been examined. Overall, dispersion parameters based on measurements made near Jülich, Federal Republic of Germany, give the best comparisons between observed and predicted air concentrations. The commonly used vertical temperature gradient method for determining atmospheric stability class consistently gives poor results. The accuracy of air concentration predictions improves when dry deposition processes are included in the model. Further validation studies using various Hanford data sets are planned.

AN - 78389820; 3410701 AB - This paper discusses the relationship between standards for limiting radiation exposures of individuals in the general public and limitation of lifetime risk. Most current radiation standards for the public in the United States specify limits on dose for each year of exposure. Particularly for internal exposures, we show that such standards may correspond poorly with a limit on lifetime risk when the age dependence of radionuclide intakes and dose is taken into account. We then show that standards which specify limits on annual dose averaged over a lifetime, with a subsidiary limit on dose in any year, correspond more closely with a limit on lifetime risk. Finally, we discuss standards for public exposures that are expressed directly as limits on lifetime risk. The development of risk standards would require consideration of age-dependent radiogenic risks and competing risks from all other causes as well as age-dependent dosimetry. We present sample calculations of lifetime risks from acute and chronic intakes that would support such a standard. We suggest that implementation of a standard for lifetime risk would require modification or abandonment of several radiation protection practices embodied in standards which specify limits on dose.

AN - 78385381; 3410682 AB - The current radiation protection guidelines of the National Aeronautics and Space Administration (NASA) were recommended in 1970. The career limit was set at 4.0 Sv (400 rem). Using the same approach as in 1970 but current risk estimates, a considerably lower career limit would obtain today. Also, there is now much more information about the radiation environments that will be experienced in different missions. Furthermore, since 1970 women have joined the ranks of the astronauts. For these and other reasons, it was considered necessary to re-examine the radiation protection guidelines. This task has been undertaken by the National Council on Radiation Protection and Measurements Scientific Committee 75. Within the magnetosphere, the radiation environment varies with altitude and inclination of the orbit. In outer space missions, galactic cosmic rays, with the small but important heavy-ion component, determine the radiation environment. The new recommendations for career dose limits, based on lifetime excess risk of cancer mortality, take into account age at first exposure and sex. The career limits range from 1.0 Sv (100 rem) for a 24-y-old female up to 4.0 Sv (400 rem) for a 55-y-old male, compared with the previous single limit of 4.0 Sv (400 rem). The career limit for the lens of the eye has been reduced from 6.0 Sv (600 rem) to 4.0 Sv (400 rem).

AN - 78286175; 3290332 AB - We are interested in developing monoclonal antibodies (MoAbs) that recognize specific cell types in the lung of BALB/c mice. Normal mouse lung homogenate was used to immunize F344 rats and hybridomas were produced by fusion of rat spleen cells with mouse myeloma SP 2/0. Two hybridomas were selected which produced MoAbs active in immunohistochemistry of lung cells. MoAb 273-34A and 411-201B both show extensive peroxidase staining of capillary endothelial cells within alveolar walls of lungs at the light microscopic level. To demonstrate cell specificity, immunoelectron microscopy with gold-labeled antibody was performed. Lightly fixed lungs were frozen and thin-sectioned before staining with MoAb and 5-nm gold particles coupled to secondary antibody. Quantitative analyses of these cryosections show that both antibodies, used at optimal concentrations, are specific for binding to capillary endothelial cells. More than 95% of the gold particles are associated with capillary endothelial cells on the thin side of the alveolar wall. When capillaries adjoined thick septa containing interstitial cells, about two thirds of the gold particles were associated with endothelial cells and about one quarter with interstitial cells. These MoAbs should be useful in studying the role of endothelial cells in toxic lung injury.

An Evaluator's Dream AN - 292041800; 11009213 AB - The Hood River Conservation Project (HRCP) was a major residential conservation project, intended to test the upper limits of a utility retrofit program. It was proposed by the Natural Resources Defense Council, funded by the Bonneville Power Administration (Bonneville) and operated by Pacific Power & Light Company (Pacific) in Hood River, Oregon. Thisfive-year, $20 million research and demonstration project installed as many cost-effective conservation measures in as many electrically heated homes in Hood River as possible. The measures were aimed at the building shell to reduce electricity use for space heating and at water-heating retrofits. This article summarizes the remarkable (and largely successful) efforts to design a comprehensive evaluation to address energy-policy issues important to the Pacific Northwest. Evaluation results are presented concerning project performance in three critical areas: the number of eligible households that participated, the number of recommended conservation actions adopted by participants and financed by HRCP, and the actual electricity use and savings achieved by HRCP.

AN - 78244052; 3375429 AB - We have examined two interrelated questions: is the susceptibility for radiogenic cancer related to the natural incidence, and are the responses of cancer induction by radiation described better by an absolute or a relative risk model. Also, we have examined whether it is possible to extrapolate relative risk estimates across species, from mice to humans. The answers to these questions were obtained from determinations of risk estimates for nine neoplasms in female and male C3Hf/Bd and C57BL/6 Bd mice and from data obtained from previous experiments with female BALB/c Bd and RFM mice. The mice were exposed to 137Cs gamma rays at 0.4 Gy/min to doses of 0, 0.5, 1.0, or 2.0 Gy. When tumors that were considered the cause of death were examined, both the control and induced mortality rates for the various tumors varied considerably among sexes and strains. The results suggest that in general susceptibility is determined by the control incidence. The relative risk model was significantly superior in five of the tumor types: lung, breast, liver, ovary, and adrenal. Both models appeared to fit myeloid leukemia and Harderian gland tumors, and neither provided good fits for thymic lymphoma and reticulum cell sarcoma. When risk estimates of radiation-induced tumors in humans and mice were compared, it was found that the relative risk estimates for lung, breast, and leukemia were not significantly different between humans and mice. In the case of liver tumors, mice had a higher risk than humans. These results indicate that the relative risk model is the appropriate approach for risk estimation for a number of tumors. The apparent concordance of relative risk estimates between humans and mice for the small number of cancers examined encourages us to undertake further studies.

AN - 78196189; 3362157 AB - In an earlier study (Generoso et al., 1987), it was observed that the mutagen, ethylene oxide (EtO), produced remarkable increases in the incidence of developmental abnormalities and death of fetuses when early zygotic stages were exposed. This is a major finding in experimental induction of embryopathy, implicating genetic damage to the zygotes as the likely cause. In the subsequent study reported here, 3 other mutagens--ethyl methanesulfonate (EMS), ethyl nitrosourea (ENU), and triethylene melamine (TEM), were studied for embryopathic effects following exposure of dictyate oocytes, prefertilization oviducal eggs and sperm, early pronuclear zygotes, zygotes undergoing pronuclear DNA synthesis, and two-cell embryos. All 4 mutagens produced developmental abnormalities among living fetuses following exposure of early pronuclear zygotes (the only stage studied for this endpoint in this report). With respect to stage specificity and gestational timing of death of conceptuses, EMS and EtO on one hand and ENU and TEM on the other, are very similar to one another. EMS, like EtO, produced a high incidence of midgestation and late fetal deaths only in prefertilization oviducal eggs and sperm and in early pronuclear eggs. In contrast, ENU and TEM produced high losses of conceptuses in all postmating stages studied but death occurred primarily prior to or around the time of implantation. Thus, the frequency of induction and the expression of embryopathy, which ranged from early embryonic preimplantation and late fetal deaths to subtle fetal anomalies, are dependent upon the stage exposed and the mutagen used.

AN - 78196183; 2896501 AB - Both activities of ribulose bisphosphate carboxylase/oxygenase are dependent on carbamylation by CO2 of a specific lysyl epsilon-amino group (Lys-191 of the enzyme from Rhodospirillum rubrum). To examine the stringency of the requirement for this lysyl side chain, Lys-191 was converted to an aminoethylcysteinyl residue (net replacement of a gamma-methylene group by a sulfur atom) by a combination of site-directed mutagenesis and subsequent chemical modification. The purified Cys-191 mutant was totally devoid of both carboxylase and oxygenase activities. However, this mutant protein exhibited tight-binding of the transition-state analogue, 2-carboxyarabinitol bisphosphate, a property heretofore ascribed solely to the carbamylated form of the carboxylase. Treatment of the mutant protein with ethylene imine restored catalytic activity to 4-7% of the wild-type level. The carboxylase:oxygenase activity ratio of the aminoethylated protein was unperturbed relative to that of wild-type enzyme.

AN - 78157845; 3127395 AB - Substitutions for active-site lysyl residues at positions 166 and 329 in ribulosebisphosphate carboxylase/oxygenase from Rhodospirillum rubrum have been shown to abolish catalytic activity. Treatment of the Cys-166 and Cys-329 mutant proteins with 2-bromoethylamine partially restores enzyme activity, presumably as a consequence of selective aminoethylation of the thiol group unique to each protein. Amino acid analyses, slow inactivation of the wild-type carboxylase by bromoethylamine, and the failure of bromoethylamine to restore activity to the corresponding glycyl mutant proteins support this interpretation. The observed facile, selective aminoethylations may reflect an active site microenvironment not dissimilar to that of the native enzyme. Catalytic constants of these novel carboxylases, which contain a sulfur atom in place of a specific lysyl gamma-methylene group, are significantly lower than that of the wild-type enzyme. Furthermore, the aminoethylated mutant proteins form isolable complexes with a transition state analogue, but with compromised stabilities. These detrimental effects by such a modest structural change underscore the stringent requirement for lysyl side chains at positions 166 and 329. In contrast, the aminoethylated mutant proteins exhibit carboxylase/oxygenase activity ratios and Km values that are unperturbed relative to those for the native enzyme.

AN - 85171362; pmid-3286711 AB - A technique for ultrasonic imaging based on the theory of diffraction tomography is presented. The method utilizes a fixed, circular configuration of transmitters and detectors. This configuration was selected because it avoids many practical limitations associated with the design of a medical imaging device. Practical considerations also motivated the inclusion of effects associated with the transmitter beam pattern rather than pursuing the more conventional approach in which plane-wave illumination is required. In addition, the problem of separately imaging both density and compressibility variations is considered.

AN - 78785666; 3151016 AB - The unusual chemical properties of active-site Lys-329 of ribulose bisphosphate carboxylase/oxygenase from Rhodospirillum rubrum have suggested that this residue is required for catalysis. To test this postulate Lys-329 was replaced with glycine, serine, alanine, cysteine, arginine, glutamic acid or glutamine by site-directed mutagenesis. These single amino acid substitutions do not appear to induce major conformational changes because (i) intersubunit interactions are unperturbed in that the purified mutant proteins are stable dimers like the wild-type enzyme and (ii) intrasubunit folding is normal in that the mutant proteins bind the competitive inhibitor 6-phosphogluconate with an affinity similar to that of wild-type enzyme. In contrast, all of the mutant proteins are severely deficient in carboxylase activity (less than 0.01% of wild-type) and are unable to form the exchange-inert complex, characteristic of the wild-type enzyme, with the transition-state analogue carboxyarabinitol bisphosphate. These results underscore the stringency of the requirement for a lysyl side-chain at position 329 and imply that Lys-329 is involved in catalysis, perhaps stabilizing a transition state in the overall reaction pathway.

AN - 78151578; 3353997 AB - A physiological pharmacokinetic model is developed to describe the pharmacokinetics of tetrachloroethylene (PCE) in mice, rats, and humans. The body is divided into four tissue compartments (vessel-rich, muscle, slowly perfused fat, and liver) connected by the arterial and venous blood flow pathways. The physiological parameters of the model are blood flow rates, cardiac output, tissue volumes, ventilation rate, and tissue/air and blood/air partition coefficients. Metabolism is assumed to occur only in the liver compartment and is described by a combination of a linear metabolic component and a Michaelis-Menten component. The metabolic parameters for PCE were determined by fitting model predictions to species-specific empirical data. Comparison of model results with independent empirical data on inhalation and gavage exposures in mice, rats, and humans demonstrates that the physiological pharmacokinetic model can be used to determine the time course of PCE in these species. We show that human metabolic parameters can be predicted by scaling rat metabolic parameters as a function of body weight, whereas scaling of the metabolic parameters of mice overestimates human metabolism.

AN - 78240605; 3375501 AB - This paper reexamines the scaling approaches used in cancer risk assessment and proposes a more precise body weight scaling factor. Two approaches are conventionally used in scaling exposure and dose from experimental animals to man: body weight scaling (used by FDA) and surface area scaling (BW0.67--used by EPA). This paper reanalyzes the Freireich et al. (1966) study of the maximum tolerated dose (MTD) of 14 anticancer agents in mice, rats, dogs, monkeys, and humans, the dataset most commonly cited as justification for surface area extrapolation. This examination was augmented with an analysis of a similar dataset by Schein et al. (1970) of the MTD of 13 additional chemotherapy agents. The reanalysis shows that BW0.75 is a more appropriate scaling factor for the 27 direct-acting compounds in this dataset.

AN - 78119225; 3257956 AB - Many radiation-induced lethality experiments have been published for various mammalian species. From those studies a subset of studies reflecting useful biological and physical variables has been compiled into a database suitable to study interspecific variability of radiosensitivity, dose-rate dependence of sensitivity, dose-response behavior within each experiment, etc. The data compiled were restricted to continuous and nearly continuous exposures to photon radiations having source energies above 100 keV. Photon source energy, exposure geometry, and body weight considerations were used to select studies where the dose to hematopoietic tissue was approximately uniform. The database reflects 13 mammalian species ranging in size from mouse to cattle. Some 211 studies were compiled, but only 105 were documented in adequate detail to be useful in development and evaluation of dose-response models of interest to practical human exposures. Of the 105 studies, 70 were for various rodent species, and 35 were for non-rodent groups ranging from standard laboratory primates (body weight approximately 5 kg) to cattle (body weight approximately 375 kg). This paper considers seven different dose-response models which are tested for validity against those 105 studies. The dose-response models include: right-skewed extreme value, left-skewed extreme value, log-logistic, log-probit, logistic, probit, and Weibull models. In general, the log transformation models did not improve model performance and the extreme value models did not seem consistent with the preponderance of the data. Overall, the probit and the logistic models seemed preferable over the Weibull model.

AN - 78116519; 3345581 AB - Mice were given i.v. injections of various tumor cell lines and, beginning 24 h later exposed for 3 weeks to 70% oxygen. Hyperoxia reduced the number of lung colonies derived from MT-7 cells (originally a mammary carcinoma) and of the lung-tumor derived cell lines 498 and Line-1 early passage. Lung colonies derived from Line-1 late passage, lines M109, B16-F10 and Lewis lung carcinoma were oxygen resistant. Lung metastases following i.m. injection of MT-7 cells were oxygen-sensitive and metastases derived from B16-F10 cells or Lewis lung carcinoma were oxygen resistant. Pre-exposure of mice for 48 h to 100% oxygen enhanced colony formation for all cell lines examined whereas exposure to 100% oxygen after i.v. injection only curtailed the growth of the cell lines previously shown to be sensitive to 70% oxygen. There was no correlation between oxygen sensitivity or resistance and the levels of total glutathione or activities of superoxide dismutase (SOD), glutathione reductase or peroxidase or glucose 6-phosphate dehydrogenase in the cell lines. However, upon injection in mice a resistant cell line increased its anti-oxidant defense mechanisms while growing in vivo whereas a sensitive cell line failed to show such adaptation.

AN - 78093527; 3338106 AB - A comparison of the rates of elimination of [3H]benzo[a] pyrene (BaP) and 7,8-dihydro-7,8-diol-[3H]benzo[a]pyrene (BPD), after subcutaneous injection into Fischer 344 rats, shows they are both eliminated at about the same rates and with the same pattern over at least 7 days post-exposure. The end-rate of combined urinary and fecal excretion was approximately 40 nmol/day. About 20% of the injected BaP and approximately 3% of the injected BPD remained at the site of injection for at least 9 days. The remainder was distributed throughout the animal. If the rate of excretion continued at the observed steady-state rates, the BaP and BPD could persist for up to 40 days for each milligram of injected substance. The concentration of excretion products were highest during day 1 and day 2 following exposure, decreased exponentially to a concentration of approximately 0.5 microM (mixed metabolites) by day 5 following exposure, and then continued to be excreted at that rate. Feces contained the highest total amounts of radioactivity, which were approximately 2- to 4-fold higher than the amounts in urine and approximately 15- to 50-fold higher than in total blood. The conversion of organic 3H to 3H2O during the experimental period indicates that whole-body phenol(quinone) formation was significant for BaP metabolism, but was much less for BPD metabolism. When BaP was injected, both blood and urine contained water-soluble, volatile tritium counts (3H2O). Injection of BPD resulted in volatile 3H2O in urine but not in blood. The persistence of BaP and BPD metabolites in skin, blood, urine and feces compartments indicates there is a substantial reservoir of the chemical(s) that could be used to replenish repaired or discarded DNA adducts.

Some improvements in the correlations are found by employing a two-parameter fit to a given set of toxicity data.

AN - 78097809; 3276033 AB - Lung cancer in man is a common disease. There is some recent concern that oxidant air pollutants might be a contributing risk factor. Experimental data show that ozone and NO2 increase incidence and multiplicity of lung tumors in strain A mice; however, the data are not always statistically significant. Also it depends on experimental design whether ozone enhances or inhibits the development of lung tumors in mice. Similarly, ozone and nitrogen dioxide enhance lung colonization by cancer cells injected intravenously following exposure to the air pollutants, whereas NO2 kills lung metastases if cells are injected prior to exposure. Both ozone and NO2 modulate the proliferation of pulmonary neuroendocrine cells, the precursor cells for small cell lung cancer. It is concluded that there is little evidence to implicate ozone or NO2 directly as pulmonary carcinogens, but that they might modify and influence the carcinogenic process in the lung.

AN - 78080536; 3336375 AB - DNA breakage in spermiogenic stages of the mouse was studied after exposure to ethylene oxide (EtO), using an alkaline elution technique. At daily intervals over a 23-day period following i.p. injection of 100 mg EtO/kg, mature spermatozoa were recovered from treated ([3H]dThd-labeled) and control ([14C]dThd-labeled) animals, lysed together on polycarbonate filters, and the DNA was eluted with a high pH (12.2) buffer. Elution of germ-cell DNA from EtO-exposed animals increased (more DNA strand breaks) in stages sensitive to the genetic effects of EtO (late spermatids to early spermatozoa). The stage-related pattern of EtO-induced DNA breakage paralleled the pattern of sperm alkylation and protamine alkylation found to be produced by EtO in an earlier study (Sega and Owens, 1987). At 9 days posttreatment (sperm sampled were in late-spermatid stages at the time of EtO exposure) the amount of sperm DNA eluted did not change significantly over a pH range of 11.6-12.8, indicating that, at the time of assay, DNA breaks were already present in the sperm.

Existing and potential new applications of topographic information and important scientific questions that require complete topographic information form the focus of this report. The report has three specific goals. First, it emphasizes the idea that a moderate-to high-resolution topographic data set has abundant scientific applications in many diverse fields and gives specific examples. Second, it points out that global continental topography is poorly and unevenly known at all but the coarsest resolution. Finally, it suggests that coherent topographic data with resolution adequate for many studies (50-500 m horizontal, approximately 1 to several meters vertical) can be obtained from a relatively inexpensive space mission. The existing and potential applications of high-quality topographic data are diverse. In the botanical, hydrological, soil, and ecological sciences, variations in temperature, rainfall, rain runoff, evaporation rates, and soil moisture are critical parameters that strongly depend on elevation, slope, and slope aspect. In the geological and geophysical sciences, topography combined with gravitational information provides an important constraint on the structure and rheologic properties of the lithosphere. Detailed topographic data can be used to map geological structure and thus reveal the effects of tectonic deformation. In the polar regions, data on surface elevation, and especially changes in surface elevation, are needed for studying ice sheet mass balance and ice-flow dynamics, important indicators of the CO (sub 2) -induced greenhouse effect. The vast Antarctic and Greenland ice sheets have important interactions with global sea level and climate, but it is not known whether they are growing or shrinking or how they will respond to climate change. Topographic data, where available, take the form of topographic maps, consisting of hand-or machine-drawn contours around unevenly distributed spot height measurements. For many parts of the world coverage is limited, inaccurate, or nonexistent. Mountain belts, deserts, tropical rain forests, and polar areas, all critical environments for Earth science research, suffer from topographic coverage that is totally inadequate mainly because of difficulties in physical access. Even where topographic maps exist, they may be generated in such a way as to limit their usefulness. For example, the distribution of horizontal and vertical control points across a map is usually uneven, and this results in variable accuracy. Even maps that are internally consistent can rarely be assembled to generate good regional coverage. Lack of uniformity in reference levels compromises the integrity of topographic data over larger regions. For example, the United Nations lists 18 separate reference datums (horizontal control surfaces) in use in different countries. This lack of standardization effectively limits the scope of any regional or global study where precise topography is important. Regional and global topographic studies require the manipulation of large data sets and would benefit greatly from the availability of easily accessed digital information. At present the availability of this type of data is extremely limited.....

Pure methanotrophic strains were isolated from mixed cultures by subculture on mineral salts-agarose plates at 22C in an atmosphere of 10 per cent methane. Enzyme assays for the two strains and TCE degradation assays were performed in liquid culture. Strain 46-1, a type I methanotroph degraded TCE when grown in the presence of methane or methanol. Data on the rate of and the methane dependence of growth is presented graphically. TCE biodegradation appeared to be a cometabolic process occurring when the organism was actively metabolising a suitable substrate. A proposed mechanism of TCE degradation is presented and TCE epoxide appeared to be an intermediate. The epoxide broke down spontaneously in water to form dichloroacetic acid, glyoxylic acid and one-carbon products.

The water table was simulated for the one-dimensional steady state case of a long period with no perturbations to the system in which the most important input parameters were hydraulic conductivity and aquifer bottom elevation, and for one- and two-dimensional transient cases of a single rainfall event. Although there were some problems with input data requirements and FEWA documentation, agreement was generally good between predicted and observed water table responses, indicating a potential application of FEWA for analysing contaminant transport and groundwater flow regimes at waste disposal sites.

Toxic effects could be predicted with a variability comparable to that associated with freshwater data. The standard marine test fish, Cyprinodon variegatus, appeared to be representative of marine fishes, but marine crustaceans gave highly diverse responses. More systematic testing was required to determine the relative sensitivities of marine organisms to chemical pollutants. A bibliography of 53 references is appended.

Contrasting profiles, a cherty silt loam and a silt loam, were selected. Sorptivity was determined as batch distribution coefficients using radiotracers. The organic macropore fillings exhibited higher cadmium and manganese sorptivities than did whole soils or micropore clays, which showed similar values. Sorptivity increased with increasing pH but, owing to the higher density of pH-dependent sorption sites on organic matter, did so faster for organic fillings than for whole soils or macropore clays. Results suggested that migration of cadmium and manganese would probably be more highly retarded in root-derived macropores than in other types of macropores. Factors other than sorptivity, eg hydrology, might also be important in determining migrations rates of cadmium and manganese.

Solvents tested for extracting the adsorbed DNT were water, acetone, methanol and mixtures of these solvents. Both carbons were excellent adsorbents, but the equilibrium adsorptive capacity of FS 400 was greater than that of FS 300 with or without grinding of the latter. An equilibrium loading of 800 mg DNT per g dry carbon was achieved on FS 400 for an aqueous phase concentration of 100 mg DNT per litre. Acetone and methanol were both effective solvents for DNT desorption but acetone was the more effective for removing chemicals produced during DNT adsorption.

To assess the integrity of DNA, existing methods had been modified to allow extraction of highly polymerized DNA from whole organisms and from liver, and estimate its double-strandedness. After isolation and purification, strands of DNA were separated at controlled pH and temperature, after which the preparation was neutralized and mechanically sheared in the presence of detergent. The amount of double-stranded DNA remaining after a given time was inversely proportional to the number of strand breaks at the start of alkaline exposure, and was quantified by measuring the fluorescence on addition of bisbenzimidazole. Using liver preparation from bluegill sunfish (Lepomis macrochirus), all double-stranded DNA present at zero time had unwound after 20 minutes' exposure at 80C. The technique was applied to fathead minnows (Pimephales promelas) exposed to 1 ug benzo(a)pyrene per litre for 6 days, and a progressive increase in DNA strand breaks noted, although no genotoxicity was noted and fish were able to repair the damage without deleterious effects.

The cores were dated using fallout calcium-137 and excess lead-210. The concentrations of several trace metals increased in sediments deposited immediately after the bombing attack on Pearl Harbour in December 1941.

Land elevations were estimated from topographic maps and dam breach and flood routing models such as DAMBRK were used to estimate flood elevations. Various land user and industrial classifications were used, and depth-damage functions estimating damages as a proportion of existing values were derived statistically. The economic, flood elevation, and depth-damage information was combined using software called DAMAGE to predict losses for different flood stages and inflow events.

The convection-dispersion equation using flux-averaged solute detection in the effluent described the movement of nonreactive tracers well: various transport codes based on the convection-dispersion equation described the movement of reactive tracers. Chemical retardation was estimated independently by dynamic isotherms developed using a steady-flow method on small undisturbed soil columns. Batch adsorption isotherms were of limited use in describing solute retardation in undisturbed column displacement experiments.

Spatial and temporal trends of metals in wet and dry deposition, and the factors influencing metal concentrations in rain, dry deposited particles, and stream water, were investigated. Trace metal mass balances were established for each catchment, and the implications of accumulation in the landscape of metals deposited from the atmosphere were assessed. Stream export of metals was controlled by pH, organic carbon, bedrock geology, and the hydrology of each site.

Regionally averaged precipitation was calibrated with the tree ring data by linear regression, and the 231-year reconstruction was verified with independent numerical climatic data available from 1893, and qualitative historical data from the mid-nineteenth century. A variance trend apparently related to tree age rather than climate was removed. The reconstruction often underestimated precipitation in wet years but was accurate for drought periods. An extremely severe drought between 1855 and 1864 exceeded any instrumentally measured drought in hydrological records, and droughts were more prolonged before 1870 than after. The probability of severe, prolonged droughts showed no increase, and was not related directly to volcanic activity. Autocorrelation suggested a weak cyclic tendency for droughts to occur at 15-25 year intervals. There are 46 references.

One group of fish, held at 26C, was fed ad libitum. All other fish were starved for 2 weeks prior to dosing. Induction of ethoxyresorufin O-deethylase (EROD) activity increased with BaP dose, but was suppressed and delayed by low acclimation temperatures. EROD induction was much greater than BaP induced increases in cytochrome P-450 and cytochrome b5, indicating that EROD was associated with only a small fraction of the cytochrome P-450 content. Data for 4 and 26C suggested that EROD activity was dependent on temperature and not on the amount of BaP accumulated in the livers, but this was not true for fish acclimated to 13C. EROD activity was unaffected by food deprivation, though cytochrome P-450 and cytochrome b5 contents were lower (p less than 0.01) in starved fish. Major changes observed in the 53- and 57-kDa electrophoretic bands suggested the association of one of these bands with EROD activation.

The decrease was most marked in exchangeable calcium and magnesium on cherty, upper slope oak-hickory and chestnut oak forests. Surface soils (0-15 cm) content either did not change or, in the case of nitrogen and exchangeable potassium in certain plots, increase. There were significant increases in exchangeable aluminium in both subsoils and surface soils of certain plots which were not accompanied by decreases in exchangeable base cations or consistent decreases in pH. There thus appeared to be a general decline in the nutrient status of forest ecosystems, particularly in cherty, upper chestnut oak and oak-hickory forests with the lowest exchangeable calcium and magnesium supplies.

The interactive computer model PHALCA was developed from survival-time data for different levels of pH, aluminium and calcium at different life stages to estimate the conditional mortality and fecundity rates. These estimates together with the life history characteristics of each species constituted the input requirements of the FISHEGGS model. The effects of acidification stress on the relative reproductive potential (RRP) of the population in each lake was then evaluated for regional analysis, and a logistic regression model was fitted, using fish presence /absence as the dependent variable and the estimated RRP as the independent variable. The probability of brook trout (Salvelinus fontinalis) occurring in 66 high-elevation lakes was predicted to illustrate the application of the network which enabled the effects of indirect factors such as fishing pressure and stocking to be compared with the chemical effects of acid rain. The flexibility of the framework and component models would enable future incorporation of new types of bioassay and field data.

AN - 77833099; 3679825 AB - A graphical method for forecasting radiation exposure rates from multi-aged fallout is extended to include a nomogram method. A simple method for forecasting accumulated radiation exposure is also presented. It is shown mathematically that these methods can provide estimates of radiation exposure rates or cumulative exposures for intervals of a few days to a few weeks in the future to within +/- 30% from assumed actual radiation exposure rates or accumulated exposures for fallout that decays according to t-n, where n is any number from 0.8 to 1.6. Because of the self-adjusting feature of the method which results in an estimated effective age for the fallout, it is not necessary to attempt to subtract contributions from separate fallouts with different ages. The method can be applied to composite fallout without knowledge of the previous history of the various-aged contributions.

AN - 81065896; 3664958 AB - The numbers of tumor-initiation sites (TIS) induced by split doses of benzo[a]pyrene (BAP) in open-ended rat tracheal implants (OETI) were quantitated as the average number of growth-altered cell populations isolated per carcinogen-exposed OETI. These growth-altered cell populations were identified as primary cell cultures which survive in medium lacking a pyruvate supplement, a condition in which normal tracheal cells die. The OETI were exposed to an average total dose of 1450 micrograms BAP, which was delivered twice weekly from 170-, 76- or 41-micrograms BAP-gelatin pellets over 4.5, 9 or 18 weeks respectively. OETI exposed for 4.5 or 9 weeks had 0.33 TIS/trachea when growth-altered cell populations were selected at 14 days from the first and second outgrowth cultures. An additional 1.0-1.17 TIS/OETI were detected if selection was delayed until 63 days in the third and fourth outgrowth cultures. In contrast, 2.0 TIS/trachea were selected after 14 days of culture from OETI pre-exposed for 18 weeks, and an additional 2.50/trachea were detected if selection was delayed to 28-63 days of culture. The TIS from this last group were also distinguished by more rapid growth and a large number of multiple cell cultures from the same explant, which indicated that more than one TIS was present on the explant and/or the growth-altered cell population had expanded enough to appear in more than one outgrowth culture. These growth-altered cell populations had also acquired a high degree (83%) of subculturability, i.e. immortality. These results suggest that OETI exposed repeatedly for a long duration had many TIS of which many had received multiple hits necessary for rapid progression of neoplasia. A large number of TIS were induced by a 4.5-week exposure, when the total BAP dose was doubled to 2934 micrograms. In this case a total of 5.75 TIS were induced per OETI. However, the cell cultures grew slowly, few multiple cultures were obtained, and only 52% of the growth-altered cell populations were subculturable.

AN - 81059420; 3667271 AB - The aerodynamic size distributions of short-lived Rn daughters (reported as 214Pb and 212Pb) in ambient aerosol particles were measured using low-pressure as well as conventional low-volume and high-volume impactors. The activity distribution of 214Pb and 212Pb, measured by alpha spectroscopy, was largely associated with submicron aerosols in the accumulation mode (0.08 to 2 microns). The activity median aerodynamic diameter ranged from 0.09 to 0.37 micron (mean 0.16 micron) for 214Pb and from 0.07 to 0.25 micron (mean 0.13 micron) for 212Pb. The mean values of the geometric standard deviation (sigma g) were 2.97 and 2.86, respectively. By comparison, the median diameters of cosmogenic 7Be and ambient SO4(2-) were about 0.24 micron higher. In almost 70% of the low-pressure impactor measurements, the activity distribution of 214Pb showed a small shift to larger particle sizes relative to 212Pb. This shift probably results from alpha-recoil detachment of parent 218Po, which preferentially depletes 214Pb from smaller particles. The subsequent recondensation of 214Pb causes an enrichment of larger aerosols. Early morning and afternoon measurements indicated that similar size associations of 214Pb occur, despite humidity differences and the potential for fresh particle production in the afternoon. Health physics implications of the results are also discussed.

Minimal evidence for concern is present on the basis of animal and plant research. General observation would accord with the implication that there is no single and manifest health effect as the result of exposure to these fields. There are persistent indications, however, that these fields have biologic activity, and consequently, there may be a deleterious component to their action, possibly in the presence of other factors. Power frequency electromagnetic field exposures are essentially ubiquitous in modern society, and their implications in the larger perspective of public health are unclear at this time. Electromagnetic fields represent a methodological obstacle for epidemiologic studies and a quandary for risk assessment; there is need for more data.

AN - 81019983; 2889042 AB - The reassessment of the radiation dosimetry from the Hiroshima and Nagasaki atomic bombs is almost complete. Since atomic bomb survivors provide a major source of data for estimates of risk of cancer induction by radiation the impact of the new dosimetry on risk estimates and radiation protection standards is important. The changes include an increase of about 20% in the estimated yield of the Hiroshima bomb and a reduction in the estimated doses from neutrons in both cities. The estimated neutron dose for Hiroshima is about 10% of the previous estimate. The neutron doses are now so small that direct estimates of neutron relative biological effectiveness may be precluded or be much more difficult. There is little change in most of the gamma ray organ doses because various changes in the new estimates tend to cancel each other out. The new estimate of the attenuation of the free-in-air kerma by the walls of the homes is about twice that used in the previous dosimetry. But the transmission of gamma radiation to the deep organs such as bone marrow is significantly greater than earlier estimates. Probably future risk estimates for radiogenic cancer will be somewhat higher because of both the new dosimetry and the new cancer mortality data. New risk estimates should be available in 1988.

AN - 77883679; 2826120 AB - Germ-line mutations of the mouse have for years comprised one class of biological markers for mammalian reproductive and developmental toxicology. Understanding the molecular nature of mutations and the mechanisms by which mutations are translated into specific (and often complex) phenotypes, however, still looms as a major goal of mammalian biology. Molecular genetic analysis of heritable mouse mutations constitutes a significant, experimentally malleable strategy for relating genomic DNA structure to genic expression and function in mammals. The integrated use of recombinant DNA technology, which allows both the identification and analysis of expression of single genes, and classical genetic and cytogenetic analysis, which allow the important correlation between basic DNA defects and the organismic consequences of such defects, has been crucial to this strategy. Some of the approaches (e.g., specific-gene cloning, random-clone analysis of genomic regions, insertional mutagenesis) for studying the nature and effect of both mutations and their wild-type counterparts that have resulted from this integration of genetic analysis and molecular biology have been applied to many loci within the murine genome. Studies of the nature and effects of a complex set of radiation-induced mutations at the dilute-short ear (d-se) region of chromosome 9, a specific example of this type of integrated analysis, are discussed.

AN - 81013429; 3653572 AB - The skin tumorigenic potential of seven complex hydrocarbon mixtures was determined: a coal-derived raw blend composed of light and heavy oils, a low- and high-severity hydrotreated product of that blend, and naphthas and fuel oils from the raw blend or from natural petroleum. Male and female C3H/Bdf mice were exposed three times per week to each test mixture by dermal application of 50 microliters of neat, 50, or 25% (w/v) preparations. Room, vehicle, and benzo[alpha]pyrene control groups were run concurrently. The raw blend produced an almost 100% incidence of skin tumors at all three doses while tumorigenicity was considerably decreased by hydrotreating the blend both in terms of incidence and onset. The tumorigenicities of the naphthas and fuel oils derived from the raw blend or from petroleums were low relative to that of the parent mixture. Although tumorigens in the raw blend were much reduced by hydrotreatment, tumorigenicity of the other agents did not parallel the content of polycyclic aromatic hydrocarbons known to be good tumor initiators.

AN - 81057630; 3662812 AB - Exposure of hamster embryo cells and BF lymphoblastoid cells to 18 known toxic substances and four nominally nontoxic substances results in the release of pyrimidines (and their nucleosides) into the culture medium. The extent of release is dependent on the specific chemical and the specific cells present in the assay. BF cells are not affected by exposure to benzo(a)pyrene, while the hamster embryo cells exhibit enhanced excretion on exposure to benzo(a)pyrene. This difference in response may be due to the difference in endogenous aryl hydrocarbon hydroxylase (BaP) activity. In contrast, diethylstilbestrol, which is metabolized by a peroxidase-mediated enzyme system, causes enhanced excretion in both cell types. Direct alkylating agents and Ni(+2) salts also cause enhanced excretion in both cell types. We have used concentrations of chemicals that give a 5% enhanced excretion as the criterion of low-dose response. Within the range of concentrations tested, chromate induces enhanced excretion in BF cells but not the HEC cells, and Pb(+2) induces enhanced excretion in HEC cells but not the BF cells. Benzene, dimethylnitrosamine, and Mg(+2) did not affect either cell type. 7,12-Dimethylbenzo(a)anthracene, anthracene, benzo(a)anthracene, phenylazoaniline, N-methyl, N-nitroso, N'-nitroguanidine, dioxane, and pyrene cause enhanced excretion in the hamster embryo cells while benzo(e)pyrene, ZnSO4 and cholesterol do not cause enhanced excretion in the hamster embryo cells. Of those chemicals causing enhanced excretion, the concentration range bracketing 5% enhanced excretion approximated low-dose exposures reported to result in toxic responses like cancer, teratogenesis or pulmonary disease.

AN - 78030036; 3449758 AB - Previously, we have shown that Chinese hamster ovary (CHO) cells are useful for quantifying chemical-induced gene mutations. We have defined the conditions of a Multiplex CHO System which permits determination of mutagen-induced chromosome aberration, and sister chromatid exchange (SCE) in addition to cytotoxicity and gene mutation in the same treated culture. This allows us to extend the spectrum of quantitative mutagenesis to include clastogenic endpoints. In the present study, we used four carcinogenic/noncarcinogenic pairs to validate the relative utility and sensitivity of each endpoint, and to study the interrelationship of these four distinct biological effects. These compounds include the direct-acting carcinogens N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), ICR 170 and their noncarcinogenic analogue N-methyl-N'-nitroguanidine (MNG) and ICR 170-OH, and the procarcinogens benzo[a]pyrene (B[a]P) and dimethylnitrosamine (DMN) and their noncarcinogenic analogues pyrene and dimethylamine (DMA) respectively. A rat liver homogenate preparation (S9) was used to assay for the biological activities of procarcinogens. Under our experimental conditions, we observed that carcinogens DMN, B[a]P, MNNG and ICR 170, but not their noncarcinogenic counterparts, showed all four biological effects. Our studies with these chemicals showed that cytotoxicity does not necessarily correlate with any of the genetic endpoints. On a molar basis, noncarcinogens, pyrene and ICR 170-OH show similar toxicity to carcinogens B[a]P and ICR 170, respectively. The other two non-carcinogenic analogues, DMA and MNG, exhibit minimal toxicity at concentrations 10-1,000 times higher than cytotoxic concentrations of the corresponding carcinogens, DMN and MNNG. In general, gene mutation and SCE are more sensitive than chromosome aberration assay. The gene mutation assay is more specific than SCE and chromosome aberration assays since none of the noncarcinogens exhibit a detectable response in the gene mutational assay. ICR 170 and MNNG are much more active than B[a]P and DMN as ranked on a molar basis. These results indicate that the Multiplex CHO System is capable of discriminating divergent structural classes of carcinogenic and noncarcinogenic compounds, such as the eight chemicals chosen for our study.

Four broad classes, comprised of 19 specific categories, of uncertainties in decision making in such organizations were identified: (1) ability to interpret the impending event, (2) communications, (3) perceived impacts of the warning, & (4) exogenous influences. Primary problems included recognition of the hazardous event & physical ability to communicate information with others in the chain of warning dissemination. It is concluded that decision-making uncertainty, at all levels & stages of warning systems, has been a major constraint to warning effectiveness & would well be a prime object to be mitigated by future warning system preparedness activities. 3 Tables, 1 Figure, 62 References.

The Cultural Approach to Societal Technology Choice AN - 60922529; 87T0285 AB - A discussion challenging dominant assumptions of societal risk management, including the assumption that the challenge of risk management is to minimize adverse elements without incurring excessive costs. The critical issue of "how safe is safe enough?" is analyzed, & a pilot study involving the market acceptability of a new nuclear-power reactor technology is presented as an example of a broad interdisciplinary approach to risk management. In Risk, Technology, and Society, Adrian R. Tiemann (Digital Interface & Systems, 512 West 143 St, New York, NY) provides a sociohistorical background on the debate based on a social constructionist view of reality. 1 Table, 14 References. F.

AN - 77931903; 3432939 AB - The promotion effects of 0.1% formaldehyde (HCHO) in phosphate-buffered saline (PBS) were tested in rat tracheal implants preexposed to a minimal carcinogenic dose of 468 micrograms benzo(a)pyrene (BAP) released over one month from 865 micrograms BAP-beeswax pellets. At the time of pellet removal, the tracheas were made into open-ended, flow-through, tracheal implants (FTTI), and exposed twice/week to HCHO for 30 weeks. Morphological alterations in the FTTI were monitored biweekly by collection of exfoliated cells from the luminal washings for cytopathologic diagnosis, and periodically by sacrificing animals for histopathology. FTTI exposed to the BAP followed by 30 weeks of HCHO had extensive squamous metaplasia, a high proliferation index of 7.87 [3H]thymidine-labeled cells/mm basement membrane, and foci of moderate and marked atypia. Clear diagnosis of some of the lesions was difficult because of the acute toxic effects of the repeated exposures to HCHO. These effects were seen in the tissues as well as in the exfoliated cells, which attest to the latter as an efficient, non-destructive, method for determining the responses of the tracheas to exposure to toxic and carcinogenic agents. FTTI exposed to BAP followed by twice weekly PBS, had a mostly flattened epithelium, and a low proliferation index (0.39). FTTI exposed to beeswax pellets, followed by the HCHO had a relatively high proliferation index (4.20) in a mucociliary epithelium exhibiting some basal cell hyperplasia. Control FTTI had a normal mucociliary epithelium with a proliferation index of 1.52 [3H]thymidine labeled cells/mm basement membrane.

The characteristics used to determine the degree of collective behavior are emergent norms, emergent social structure, & spontaneity. Results show that the SMOs generally had a high degree of emergent social structure, while the disaster groups were high on all 3 dimensions. The protest & gather cases generally had a high degree of emergent norms. It is concluded that SMOs are a form of collective behavior, although they are not identical to other types of collective behavior.

ATP levels (to represent microbial biomass) on rock surfaces and in fine-grained sediments, bacterial numbers in sediments, and bacterial production in sediments and rock surfaces were measured. Microbial biomass was significantly correlated with pH, and bacterial production was higher at high-pH sites than low-pH sites. Bacterioplankton were not correlated with pH, but with seston concentrations, and bacteria in the sediments were correlated with organic content of the sediment rather than with the pH of the overlying water. The major detectable impacts of acidification on microbial communities in these streams appeared to be on the epilithic community, probably because of the unbuffered nature of the habitat.

The equilibrium model adequately described the elution of the unretarded solute, but not the elution of the hydrophobic tracers. The nonequilibrium model performed much better, with the two-site model, calibrated to trichlorobenzene breakthrough data, successfully predicting the elution of tetrachlorobenzene.

With 2 per cent wastewater, degradation occurred at 5-15 mg phenols per litre.minute. Biological activity was not inhibited. With 50 per cent wastewater, the degradation rate was lower (7-11 mg phenols per litre.minute). Removal of phenolics exceeded 99 per cent and COD removal was 75-85 per cent. Batch reaction rates were higher than continuous reaction rates. Sludge production (0.34 g wet sludge per g phenol degraded) was comparable to rates in suspended growth systems. The process had lower investment and operating costs than an activated sludge process.

Comparison of distributions of the basic physico-chemical properties that control cross-media transport with the cross-media partition profiles demonstrated that significant cross-media partitioning could be expected for the majority of organic chemicals released to the environment.

In addition, the pore water chemistry of one of the lakes, Little Rock lake, Wis., was studied to assess the effect of solute transport between sediment and the water column. All the study lakes had lower than expected sulphate concentrations, given atmospheric wet deposition and evapotranspiration. In Little Rock lake, the sediments were a source of total alkalinity and calcium and a sink for sulphate ions. The sediment-water column exchange of total alkalinity, calcium, and sulphate was significant in the whole-lake budgets of the lake for these ions.

The reproductive competence of the Cherokee fish was lower than that of fish from the other two reservoirs. Fewer females spawned successfully, and early embryo survival was reduced. In Cherokee reservoir, the amount of water cool enough (below 25C) and sufficiently oxygenated (over 2.0 mg dissolved oxygen per litre) to sustain adult striped bass was severely restricted during most summers. The author suggested that the low reproductive competence of Cherokee striped bass was related to the severe stresses induced by summer habitat constriction. This hypothesis was supported by hatchery records which showed an improvement in Cherokee reproductive success after summers with high reservoir flushing rates.

Analytical data are reported for samples obtained under steady-state conditions, indicating that the effluent closely resembled that from other gasification plants and would thus be susceptible to treatment by similar methods. A proposed sequence of treatment operations is outlined, based on previous studies with effluents of this kind. JF - Electric Power Research Institute.

Effects on parental survival, fecundity, hatching success, larval survival, weight of early juveniles, and weight of early juveniles per egg were used to derive concentration-response relationships by nonlinear regression. On average, reduction in fecundity was the most sensitive parameter and hatching success was least sensitive. At maximal acceptable toxicant concentrations (MATC's), fecundity was reduced by 42 per cent, and hatching success by 12 per cent. Results indicated that early life stage and larval tests were not appropriate substitutes for life cycle tests, and that effects associated with MATC's could be substantial. Although the fathead minnow appeared to be less sensitive than other species, differences were small relative to variance among species, and thus the fathead minnow was reasonably representative of freshwater fish. It was suggested that the terms acute and chronic toxicity should be replaced by tests and benchmarks based on concentration-duration-response dynamics.

The concentrations of toxic metals in leachates from ashes leached with water and with municipal waste leachate are tabulated. Leachates from mono-disposal systems were alkaline, while those from co-disposal were more acid. Leachates from several of the ashes leached with municipal waste leachate contained metal concentrations exceeding federal standards for drinking water. Of the various extraction tests used in this study, the Waste Extraction Test procedure used in California was an aggressive method which over-estimated the metal concentrations in the leachates; it would, therefore, be conservative in identifying which ashes would be suitable for landfill disposal.

Their approach involved fitting the logistic concentration-response function to full life cycle toxicity data. The functions, together with confidence bands quantifying associated uncertainties, were then linked to simple fish population models used to assess the effects of other anthropogenic stresses (fishing, power plants) on fish populations. In the absence of chronic data for the species of interest, a concentration-response function and confidence bands could be obtained by extrapolating from acute toxicity data for the species of interest, or by extrapolating from data obtained in another species.

Leaf material was incubated in situ using flow-through plastic chambers which excluded macroinvertebrates. Bacterial production (thymidine incorporation) and microbial respiration on leaf material were significantly higher at the Cole creek site, but there were no significant differences in Adenosine triphosphate standing stock. Oxalate-extractable aluminium concentrations on the leaf material stabilized within 4 weeks (4.66 and 1.70 mg per g at low and high pH sites, respectively). After 4 weeks incubation, some exposure chambers were transferred from Cole creek to Trout Branch and vice versa. Negative effects were apparent within 1 week of transfer to low pH, but positive effects associated with circumneutral conditions did not become apparent until 4 weeks after transfer. These results implied that leaf decomposition might be slower in acidified systems.

The simple advection-dispersion model described the elution curve of the tritiated water well, but did not accurately describe the rapid elution of sodium-22. The 2-region/2-site model fitted the sodium-22 data best. Neither strontium-85 nor zinc-65 were observed in effluent from the column.

These have been computed with a new molecular mechanics program specifically designed to define distortions imposed by such adducts, and employing a rational strategy for searching the conformation space of a DNA molecule with covalently linked carcinogen. In alternating G-C sequences, the AAF adduct prefers to reside at the exterior of an undeformed Z-helix. It can also induce base displacement with attendant denaturation and helix bending in sequences that disfavor the Z form, but undeformed B helices are excluded. The AF adduct, by contrast, prefers the major groove of an unperturbed B-helix, but can also induce carcinogen-base stacking in single stranded regions of the DNA, such as at the replication fork.

Model data requirements are much lower than those of evaluations, & models can yield policy results much more quickly. The modeling approach was used to develop a low-cost monitoring scheme for the Bonneville (Utah) Power Administration Residential Weatherization Program, using 3 years of evaluation data (1981, 1982, & 1983). Results suggest that the modeling approach is most effective when program characteristics & actors & the external environment are stable over time. In this application, modeling results changed between 1982 & 1983. The defensibility of predictions yielded by streamlined evaluations is discussed. 5 Tables, 3 Figures, 10 References.

AN - 76659680; 11537230 AB - The radiation protection guidelines of the National Aeronautics and Space Administration (NASA) are under review by Scientific Committee 75 of the National Council Protection and Measurements. The re-evaluation of the current guidelines is necessary, first, because of the increase in information about radiation risks since 1970 when the original recommendations were made and second, the population at risk has changed. For example, women have joined the ranks of the astronauts. Two types of radiation, protons and heavy ions, are of particular concern in space. Unfortunately, there is less information about the effects on tissues and cancer by these radiations than by other radiations. The choice of Quality Factors (Q) for obtaining dose equivalents for these radiations, is an important aspect of the risk estimate for space travel. There are not sufficient data for the induction of late effects by either protons or by heavy ions. The current information suggests a RBE for the relative protons of about 1, whereas, a RBE of 20 for tumor induction by heavy ions, such as iron-56, appears appropriate. The recommendations for the dose equivalent career limits for skin and the lens of the eye have been reduced but the 30-day and annual limits have been raised.

A whole-lake alkalinity and ion budget for Lake 223 showed that 66- 81% of the added sulfuric acid was neutralized by alkalinity production in the lake. Nearly 85% of in situ alkalinity production was accounted for by net loss of sulfate through bacterial sulfate reduction, coupled with iron reduction and iron sulfide formation, in littoral sediments (60%) and in the hypolimnion (25%). Exchange of hydrogen ion for calcium and manganese in the sediments accounted for 19% of the alkalinity generated, while other cations were net sinks for alkalinity. Alkalinity input from the watershed of Lake 223 was very small, averaging about 5% of that produced in the lake. The seasonal production of 1,000 mu eq liter super(-1) alkalinity in the anoxic hypolimnion of this softwater lake could be attributed to bacterial sulfate reduction coupled with iron sulfide formation, ammonium production, and iron (II) production. Only the alkalinity produced from bacterial sulfate reduction coupled with iron sulfide formation remained throughout the annual cycle.

Distribution coefficients of the cations were also increased. Acid strength of the functional groups from the acid treatment was greater than those of the original material. Surface area measurements and small angle neutron scattering indicated that the increase in cation exchange capacity was not associated with gross changes in structure of the carbon. Carbon-13 NMR on solid samples suggested that the concentrations of carboxyl and phenolic functional groups in the carbon were increased by the treatment.

Technetium, cobalt and uranium mobility was due to low molecular weight anionic complexing. Strontium and caesium concentrations were low. Plutonium contamination near the trench resulted from radioactive curium migration and subsequent decay. Seasonal variations in radionuclides in the groundwater in the north end of the trench suggested contamination when the groundwater level rose or when precipitation infiltrated during drainage. Transport pathways from the trench to the seep area appeared to be associated with fault zones and folds.

The MCL, set as close as possible to the RMCL, accounted for feasibility, cost and health protection. Current revision of the primary and secondary drinking water regulations by the U.S. EPA included consideration of risk to achieve increased consistency across standards. Tabulated estimated excess individual lifetime cancer risks of different contaminants varied widely from 0.02 to 0.000002. Contaminants with individual lifetime cancer risks of less than 0.000001 were adequately regulated. Population risks and economic cost-effectiveness calculations were the primary determinants of regulation for contaminants in the range 0.000001 to 0.001. The risks associated with several contaminants, including arsenic, 1,-1-dichloroethylene and trihalomethanes, appeared high but others were regulated more stringently than necessary from a health perspective. A more rational basis for drinking water standards would include both individual risk and population risk. Studies of non-carcinogenic risk of lead, particularly in babies and young children, had shown that the proposed RMCL for lead would not allow an MCL to be set low enough to adequately protect human health. An RMCL of zero would allow more flexibility in the revision of the MCL. JF - Environmental Science & Technology AU - Munro, N B AU - Travis, C C AD - Oak Ridge National Laboratory, Tenn.

Water concentrations ranged from 0.03 to 0.53 pCi per litre, and the length of time that suspended particles remained in the water column appeared to be the principal process controlling beryllium-7 concentration. Residence times of beryllium-7 in the water column ranged from a few days in estuarine areas to several weeks in high-energy environments. Inventories of beryllium-7 in sediments ranged from nil to 3.3 pCi per cm2. In the James estuary, less than 5 per cent of the expected beryllium-7 input was in the water column, and trapping efficiency for atmospherically derived beryllium-7 was between 50 and 100 per cent.

Difficulties of the oscillatory, unstable solutions that prevailed for advection-dominated transport had been overcome using an upstream weighting function. However, there were still problems with matrices that yielded divergent solutions with successive overrelaxation: these could only be overcome with direct methods. Direct methods were not practical for large field problems because of the excessive memory, time and precision requirements required for a solution. An orthogonal upstream weighting finite element scheme was developed which produced a matrix amenable to point successive overrelaxation solution strategies when used to approximate the aquifer contaminant transport equation. This scheme differed from the standard Galerkin weighting and nonorthogonal-upstream weighting schemes in that the set of weighting functions had to be orthogonal to the set of basis functions. For large problems the proposed scheme provided a useful alternative method because it gave convergent successive overrelaxation computations for all Peclet numbers.

A grassland catchment, a deciduous forest stand catchment and 2 agricultural field plots were used in the comparative study. Initial verification of the SESOIL model by comparing predicted and observed data from the grassland and forested catchments showed good prediction of surface runoff, evapotranspiration and groundwater runoff, but underprediction of soil moisture content, possibly because SESOIL gave values for the entire unsaturated soil column.

Stream pH ranged from 4.5 to 6.4, with corresponding total monomeric aluminium concentrations ranging from 0.242 to 0.018 mg per litre. Sites with a pH of 5.0 or lower were generally dominated by diatoms and, to a lesser extent, by green algae. Sites with a pH of 5.7 or higher were dominated by blue-green algae and chrysophytes. The more acidic sites had greater total cell biovolume, chlorophyll-a density, and areal primary productivity, supporting the hypothesis that densities of grazing macroinvertebrates and microheterotrophs were reduced in 2nd and 3rd order stream reaches with low pH. Low chlorophyll-a density and areal primary productivity at the larger 4th order site (pH 6.4) was attributed to increased scouring of the stream bottom. Experiments involving short term manipulation of pH, total inorganic carbon, phosphate, and aluminium concentrations indicated that chlorophyll-specific productivity might, at times, be limited by inorganic carbon concentrations at sites with a pH less than 6, and by elevated aluminium concentrations at sites with a pH of 5 or less. Studies of phosphatase activity and phosphate turnover indicated that two of the least acidic sites were the most phosphorus limited.

The first model (PHALCA) used time-to-death data to estimate percentage survival (as a function of time) at different levels of pH, aluminium and calcium. These estimates, along with species-specific information on life history characteristics, were used in the second model (FISHEGGS). This model evaluated the reduction in reproductive potential of a fish population attributable to the effects of pH, aluminium and calcium on age-related survival and fecundity. Preliminary results from PHALCA and FISHEGGS are presented. The entire framework was currently being tested using data for brook trout in Adirondack lakes. This framework might be complementary to approaches which directly related presence/absence fisheries data to water chemistry data.

Studies were carried out to establish why some lakes in a particular region acidified and others did not. The Adirondack Catchment Database contained information on lake chemistry, elevation, area and volume and associated catchment data such as size, slope, aspect, elevation, vegetation and wetland types, beaver activity, fire and logging history and soils data. The relationships between catchment attributes and lake chemistry were studied using bivariate and multivariate procedures. There were indications that wet deposition, lake elevation and forest cover were the main variables associated with variance in data for lake pH and with acid neutralizing capacity (ANC) in the Adirondacks.

Studies were carried out on Salmo trutta and Salmo gairdneri in selected streams in the southern Appalachian mountains. Since the effects were virtually the same, data for the 2 species were combined. Trout electrocuted with pulsed DC 2-7 times in 1 year had lower growth rates than control trout. This decrease was more frequent in 1 and 2 year old trout than those of 3 years and older. It was also more frequent with recently shocked trout than those with 3 or more months to recover. Fisheries management studies should avoid repeated electroshocking and allow at least 3 months recovery. Growth rate studies were likely to be negatively biased if more than 20 per cent of the population was electroshocked repeatedly at intervals of less than 3 months.

Atmospheric CO sub(2) levels have increased approximately 25% from 1800 to 1985, attributable mainly to human influences, first from deforestation during the massive global expansion of agriculture, and now primarily from fossil fuel burning. A significant and disproportionate fraction of the overall increase has occurred, since the beginning of systematic atmospheric CO sub(2) measurements in 1958, during a period of unprecedented fossil fuel use. A doubling of the atmospheric CO sub(2) level of 1800 may produce a global average temperature warmer than during any period in the last 100,000 years or more, and the CO sub(2)-induced warming ("greenhouse effect") could be augmented significantly by increasing levels of other atmospheric trace constituents. This volume focuses on the global cycle of carbon, the dynamic balance among global atmospheric CO sub(2) sources and sinks, which determines the rate of increase in the atmospheric CO sub(2) concentration. The observed increase in CO sub(2) content of the atmosphere is less than the estimated release from fossil fuel consumption and deforestation because of interactions between the atmosphere and other global carbon reservoirs. These interactions must be understood to provide a basis for developing models that will project future changes in atmospheric CO sub(2) concentration as fossil fuel use continues. The carbon reservoirs that are known to be important in the response to anthropogenic CO sub(2) are the atmosphere, the ocean, and the terrestrial biosphere including soils.

Data on 20 indicators of inter- & intraorganizational cohesion were collected in open-ended interviews (N not provided) in an emergency response network at a nuclear power plant. Findings regarding cohesion are presented & implications for refining emergency organizational theory discussed. Overall, organizations were found to be internally cohesive, but with decreased cohesion apparent between organizations. Communications & lack of interaction clarity are identified as the primary causes of decreased interorganizational cohesion. Further investigation of the antecedents of organizational behavior that lead to cohesion breakdowns is necessary. 3 Tables, 1 Figure, 56 References.

About 45,000 chemicals are listed in RTECS, most of which have had some testing in subhuman models. RTECS entries range from cellular effects through organoleptic damage to lethality, with many pathological endpoints listed, including mutagenic changes, irritation, teratogenesis, cancer, mortality, etc. However, it is difficult to extend any biological test results to human risk assessments. If the results are extended, the degree of validity is highly uncertain. This paper describes a logical basis for using the entire complex spectrum of test results to evaluate the overall toxicological potency of a chemical to be assayed (i.e., an interviewing chemical) and describes how to derive tentative, permissible concentrations in air and water for any particular chemical for which no regulatory guidance exists. This approach has been tested for 16 reference chemicals discussed in NIOSH Criteria Documents, EPA-CAG reports, etc. The evaluations are uncomplicated, but occasionally it is difficult to match RTECS entries for two different chemicals. Difficult comparisons may require some familiarity with experimental design and the toxicological literature. One important product of this novel approach is that a distribution or array of potency values is obtained for any chemical evaluated. This distribution reflects many uncertainties stemming from low statistical power, experimental design, pharmacological processes, interspecies variability, dose rate, biological effect monitored, route of treatment, etc. The array of relative values for a particular chemical reflects many different biological and physical conditions. The distribution of the array helps to index a composite toxicological profile for many different biological effects resulting from numerous treatment protocols. To minimize the effect of extreme sensitivity of certain (perhaps novel) biological test models, possible errors in the RTECS database, and possible human pharmacological insensitivity to a particular chemical and/or a particular route of administration, we consider the interquartile range (i.e., the central 50%) of the array of relative potency values between two chemicals being compared as a practical measure of uncertainty. Thus, the range in response derived from variability in relative potency should be useful in addressing the range of response in man as estimated from extrapolations of test data.

This record is analyzed for consistency with a hypothesis that striped bass are 'squeezed' between their thermal and dissolved oxygen preferences or requirements. A commonality among diverse field and laboratory observations supports an inherent thermal niche for the species that changes to lower temperatures as fish age. This shift can cause local conditions, especially warm surface strata and deoxygenated deep water, to be incompatible with the success of large fish. Crowding due to temperature preferences alone or coupled with avoidance of low oxygen concentrations can lead to pathology and overfishing, which may contribute to population declines. Through a mixture of evidence and conjecture, the thermal niche-dissolved oxygen hypothesis is proposed as a unified perspective of the habitat requirements of the species that can aid in its study and management.

A multiple objective decision analysis was being carried out to produce an array of possible solutions, to improve quantification of environmental impacts and to include elements of uncertainty about these impacts. Details are given of the multiple objective optimization technique and its application to this area where sludge was generated at two wastewater treatment plants on Deer and Nut Islands in Boston Harbor and then pumped via submerged outfalls into the outer harbour. The Metropolitan District Commission was considering constructing a pipeline between the two islands so that the sludges could be combined and incinerated. A sludge model was developed and the net economic benefits and environmental impact of the solutions of incineration, pyrolysis, coincineration, ocean discharge, ocean barging, composting, landfilling and land application considered. Ocean disposal was clearly superior on cost grounds but worst on environmental impact, while the reverse applied for multiple disposal modes with agricultural land application in the midway position on both counts. The usefulness of this type of array of results to the decision maker when selecting on optimal solution is discussed.

Most water soluble fractions in coal liquids were readily biodegradable and would be unlikely to persist in water long enough to pose a long-term hazard unless the discharges were frequent or continuous. The acute and chronic toxicities of three water soluble fractions to various aquatic organisms (including fish, ivertebrates, and algae) are tabulated. The insoluble residue of the oil could cause physical damage to waterfowl and to benthic communities, and would be likely to persist in sediments for many months or years, causing chronic damage. Aspects on which further research is required are indicated, and a bibliography of 37 references is appended.

The computer memory requirement and convergence behaviour of the subregion iteration method was demonstrated. The finite element formulations for each subregion was the same as that for the whole region except that on the intraboundary lines between subregions the Dirichlet boundary conditions were applied using the nodal values of the previous iteration. The number of iterations for a convergent solution for each time step decreased with time.

Various analytical models were examined: those based on radial flow methods were invalid. The analysis of test results presented describe nonradial flow to a well intersected by a vertical fracture. A previously described technique, not yet applied to a field situation, was used to give estimates of matrix transmissivity in 2 directions, the storage coefficient of the matrix, and the effective length and location of the master fracture. Applications of the analytical results in this case study, and other methods derived for fractured rock or nonradial flow regimes are discussed.

Daphnid reproduction was reduced by exposure to 1.8 mg DBP per litre or 1.0 mg DOP per litre. Survival of fathead minnow embryos was decreased at 1.8 mg DBP per litre. Hatching and larval survival were reduced by 1.0 mg DPB per litre. DOP, at concentrations up to 10 mg per litre, had no effect on embryo or larval survival but hatching was significantly reduced at 10 mg DOP per litre.

Eighteen binary similarity coefficients were calculated for 5 sampling stations on a small Ohio stream which received a complex heavy metal effluent from a metal plating factory. In general, the specific- and generic-level values were highly correlated and showed similar patterns across the 10 station comparisons. The amount (average number of species per genus) and pattern (species to genus ratio trend) of information loss along the gradient was also assessed. The lack of a specific trend in the species to genus ratio indicated that the agreement between specific- and generic-level analysis was due to the ability of a robust species distribution pattern to withstand a limited amount of random information loss, rather than any inherent similarity among congenerics.

In juvenile channel catfish, 96-h LC50's for the water soluble fractions (WSF) of raw H-coal oil, water-washed H-coal oil, and the low and medium severity hydrotreated H-coal oil were 0.17, 0.80, 0.61 and 0.68 per cent respectively. In acute experiments with the high severity hydrotreated H-coal oil and with petroleum crude oil, the full strength (100 per cent) WSF's killed only 5 and 26 per cent respectively of the catfish within the 96 hours.

The model simultaneously solved algorithms for processes of oil slick spreading, oil evaporation, phenolics dissolution, advection and dispersion using an implicit integrated compartment method. In small-scale experiments, measured mean concentrations following application of a coal-liquifaction product to two ponds were approximately 84 per cent of the predicted values. With minimal calibration, SOPTRAN adequately described differential rates of dissolution of phenol and C1- to C4-alkyl isomer groups. The model was also used to simulate a hypothetical 300 m3 spillage of coal liquid into a large navigable river under both instantaneous and noninstantaneous (ie leakage) conditions. The predicted total maximal water-soluble phenolics concentration was less than 1 mg per litre.

Four criteria of reproduction were evaluated. Rate of clutch production was found to be a more sensitive indicator of stress than mean clutch size, which was significantly reduced by acridine only at 21C. Rate of egg production gave results similar to those for clutch size, and egg viability was not affected by either temperature or acridine concentration, with more than 84 per cent of eggs hatching in most cases. No reproduction occurred at the highest acridine concentration tested (3.2 mg per litre) at any temperature. The need to consider temperature when evaluating the likely effects of pollutants on aquatic ecosystems is stressed.

Chronic exposure (1.25 mg per litre for 14 days) inhibited reproduction in Daphnia and exposure to 0.9 mg per litre inhibited the growth rate of S. capricornutum by 50 per cent. These results showed that Daphnia were more sensitive to copper than were fish or algae but the most sensitive biological endpoint in tests with acridine was the inhibition of algal growth.

Daily or weekly doses of coal derived oil ranging from 0.28 to 7 ml per week were administered to aquaria containing pond water, sediment and plants. Maximal phenol concentrations were reached within the first 28 days, after which degradation rates exceeded input. After day 56 when oil inputs stopped dissolved phenols disappeared within 20 days. Microbial degradation was the major process removing phenols from the microcosm and although other processes were operating their contribution was negligible. Various rates of degradation between different alkylphenol isomers and isomer groups were noted and the removal rate of individual isomers was related to microcosm exposure history and the presence of other phenol isomers.

Multicompartment models were used to analyse the effect of binding to the humic matter on the bioavailability of PAH. Humic matter reduced the accumulation of benzopyrene by 90 per cent, but had little effect on naphthalene uptake. Approximately 97 per cent of benzopyrene, but only 2 per cent of naphthalene, was bound to humic matter. Although more benzopyrene than naphthalene was taken up by the fish, benzopyrene was extensively metabolized while naphthalene was not. As a result, there was greater bioaccumulation of naphthalene. A conceptual model describing the flux of PAH among dissolved, bound and biotic components of the aquatic ecosystem is illustrated and the implications of the results are discussed.

Three soluble grout formulations (sodium silicate, polyacrylamide, and resorcinol-formaldehyde) could both penetrate soil and sand columns and reduce hydraulic conductivity. Three particulate grouts (lime /fly ash, fly ash/cement/bentonite, and bentonite alone) could not penetrate the columns and would be unsuitable for use in closed burial trenches. Both sodium silicate and polyacrylamide were effective in reducing hydraulic conductivity of field soil. Costs would be less using sodium silicate.

Aluminium was partitioned strongly into the lower mineral soil horizons. Large stores of potentially labile aluminium were found in the soil, forest floor, and foliage. Although standing vegetation represented a relatively small pool of aluminium, it recycled substantial amounts of the metal between the soil and forest floor. There were marked seasonal fluxes as a result of fluxes of acids through the soil during winter and spring. Output of aluminium from the catchment area in stream water was dependent on the complex interactions between shallow groundwater baseflow to the stream and fluxes within and through the pine lowlands and swamps. Aluminium concentrations were relatively low in cedar swamps and pine-lowland waters, and very high in hardwood swamps. A bibliography of 42 references is appended.

Phosphate uptake from the water was highest in November and lowest in August and appeared to be limited by the abundance of coarse particulate organic matter (CPOM), and perhaps by its quality. Uptake by CPOM accounted for 26-89 per cent of the total phosphate uptake, depending on the season. Uptake length (average distance travelled by a phosphate ion dissolved in water) ranged from 22 m in November to 97 m in August. Total spiralling length of phosphorus varied from 23 m in November, just after peak autumn leaf fall, to 99 m in August and reflected primarily the travel of phosphorus in the dissolved form. Storms in early winter increased phosphorus spiralling length by virtue of their impact on the quantity and quality of coarse and fine organic particulate matter in the stream bed after the return to baseflow. Results from this study suggested that phosphorus spiralling was likely to be important to metabolic processes in Walker Branch only during late autumn and early winter, when CPOM abundance was high.

The other involved constructing a passive French drain to depress the water table at the site and prevent it reaching the bottom of the disposal trenches. The effectiveness of these systems is discussed.

A field-scale study to evaluate the effectiveness of coprecipitation of radiostrontium with calcium and magnesium carbonates is reported. An extraction procedure involving the removal of soluble salts and exchangeable cations by 1 M ammonium acetate or 1 M potassium chloride solution followed by extraction of strontium into 0.1 M hydrochloric acid /0.5 M potassium chloride solution is described. When soils supplemented by calcium carbonate coprecipitated with strontium-85 were subjected to the extraction procedure, both strontium-85 and calcium in the coprecipitate behaved identically. Soil samples collected from a waste burial trench area included some which had been treated with soda ash and some untreated. The extraction procedure indicated that up to 98 per cent of total strontium-90 was coprecipitated with calcium carbonate in treated soils, but that untreated soils exhibited 80-95 per cent of strontium-90 in a cation exchangeable form. It was concluded that strontium-90 had been coprecipitated with carbonate on treated soils, since its introduction into the soil after leaching from buried wastes.

The lead pools in upland vegetation, forest floor, and mineral soil components were estimated. Lead was strongly partitioned into mineral and organic soils which acted as efficient sinks for almost all the atmospherically deposited lead. Significant amounts of lead were leached through the forest floor in association with dissolved organic matter, to be deposited in the lower soil horizons. Lead did not appear to be physiologically accumulated by vegetation, with the exception of some herbs and shrubs, but was strongly sorbed by bark and some foliage. Lead in stream water was more mobile than reported in other systems; this was attributed to the high concentrations of dissolved organic matter and low pH of the ecosystem. Lead inputs into, and fluxes through, the system had decreased over the past 4 years. A bibliography of 38 references is appended.

Death of fish in the reservoir coincided with impingement and death of fish on the intake screens of the power plant. Increases in impingement were strongly associated with the seasonal cooling of reservoir waters. Relative numbers and size frequency of impinged shad were similar to those of shad preyed upon by sauger (Stizostedion canadense) and skipjack herring (Alosa chrysochloris), suggesting that low temperatures influenced prey vulnerability. From November 1976 to January 1977 threadfin shad made up 99 per cent of the diet of sauger and skipjack herring. The severe winter of 1976-77 caused a reservoir-wide die-off of shad. From January to April few shad were ingested. Sauger and skipjack herring caught in September and October 1977 had switched to alternative prey species.

The binding affinity (Kp) was related to the hydrophobicity of the PAH. Structure-activity relationships between Kp, DHM concentration, and bioaccumulation of PAH were developed. Results suggested that binding to DHM might mitigate the biological impact of very hydrophobic contaminants which have a high potential for bioaccumulation and transfer to man via food chains.

Classification of the various methods used in each type is shown diagrammatically. Toxicity testing was the method most likely to be used in setting permits for discharge of toxic effluents. The approach adopted by the U.S. EPA for assessing whether an effluent should be evaluated by chemical or biological methods, or a combination of both, is outlined, and recommended toxicity test methods are summarized in a table. The stance of the U.S. EPA on various issues associated with biological monitoring, such as correlation of effluent toxicity measurements to actual in-stream impact, effects of variability of effluent, exposure, species, acute-to-chronic ratio, and behaviour of toxicant after discharge, are discussed.

The opinions of 5 active groups were elicited via in-depth group discussions. Subsequent analysis of the data focused on how perceived local impacts of possible decisions differed, & what belief systems were associated with the various perceptions. The implications of individual vs interest groups' perceptions of local issues are discussed not only with regard to the TMI situation, but with regard to management of technological hazards generally. Ways to set risk levels that are acceptable are explored, & means to consider issues from the community level viewpoint suggested. 4 Tables, 1 Figure, 57 References. S.

Evaluation of Utility Energy Conservation Programs AN - 21273641; 11009039 AB - This article discusses two recent evaluations of utility energy conservation programs in which testsfor nonresponse bias were possible. In these evaluations, data were obtained both from the sponsoring utilities (fuel consumption records, energy audit reports) and from households (mail and telephone surveys). Fortunately, data from one source was usually available for those households missing datafrom the other source. This permitted comparisons of respondents and nonrespondents on several dimensions-pre- and post- program energy consumption, energy audit results, and household demographic char acteristics.

AN - 61621755; 198401896 AB - The results of two alternative approaches for estimating the energy-savings impact of Dept of Energy (DOE) conservation programs are discussed. The first analyzed program-by-program estimates that indicated DOE programs reduced US energy use by more than 0.5 quadrillion BTUs, or about 86 million barrels of oil. The second was an econometric analysis of aggregate energy use data that produced an estimate of energy savings 10 times greater than the first approach, but with a strong price effect interaction. The limitations of both approaches preclude reaching unambiguous conclusions. 3 Tables, 22 References. HA.

AN - 80925691; 11539618 AB - There are obvious risks in space travel that have loomed larger than any risk from radiation. Nevertheless, NASA has maintained a radiation program that has involved maintenance of records of radiation exposure, and planning so that the astronauts' exposures are kept as low as possible, and not just within the current guidelines. These guidelines are being reexamined currently by NCRP Committee 75 because new information is available, for example, risk estimates for radiation-induced cancer and about the effects of HZE particles. Furthermore, no estimates of risk or recommendations were made for women in 1970 and must now be considered. The current career limit is 400 rem to the blood forming organs. The appropriateness of this limit and its basis are being examined as well as the limits for specific organs. There is now considerably more information about age-dependency for radiation effects and this will be taken into account. In 1973 a committee of the National Research Council made a separate study of HZE particle effects and it was concluded that the attendant risks did not pose a hazard for low inclination near-earth orbit missions. Since that time work has been carried out on the so-called microlesions caused by HZE particles and on the relative carcinogenic effect of heavy ions, including iron. A remaining question is whether the fluence of HZE particles could reach levels of concern in missions under consideration. Finally, it is the intention of the committee to indicate clearly the areas requiring further research.

Subsidized loans are the most common type of incentive offered by utility programs, although discounts, rebates, lower rates, & free materials or labor also have been provided. Given the large sums involved in utility loan programs, an understanding of the impact of these financial incentives on retrofit investment decisions has high potential policy value. Thus, customer surveys & other studies conducted by utility companies & public commissions are reviewed, & ways that additional evidence can be obtained are suggested. A major question involves the equity issue of poorer customers paying for the subsidized loans for higher income users. 8 Tables, 23 References. Modified HA.

Here investigations carried out on the effects of artificial acid irrigation on the evolution of carbon dioxide and the concentrations of extractable nutrients in the soil in a deciduous forest in Tennessee are described. Irrigation with water, sulphuric acid, and nitric acid had no consistent effects on evolution of carbon dioxide, soil ammonia, or extractable phosphorus and aluminium. Soil nitrate was increased temporarily by irrigation with nitric acid, but was unaffected by irrigation with sulphuric acid. There was evidence of seasonal variations in all the chemical parameters measured, and this should be taken into account when monitoring long-term changes in soils.

Effects were measured at 16, 21 and 26C for both fed and unfed animals. Egg-NII LC50s increased from 1.59 mg acridine per litre at 16C to 3.44 and 3.60 mg per litre at 21 and 26C respectively. NI-CI LC50s ranged from 1.18 to 1.75 mg per litre and were unaffected by temperature. No animals survived to the NII stage at 5.6 mg acridine per litre. Unfed nauplii died faster with increasing temperature. Egg development rates were unaffected by acridine but increased with temperature as did naupliar development.

Dilute synthetic wastewaters were treated successfully by this process for over a year, and dilute actual wastewaters for 9 months. The bioreactors were stable , and no serious operating problems occurred. Effluent phenol concentration of less than 0.001 kg per m3 were achieved with a synthetic wastewater containing 0.03-0.04 kg phenol per m3, at a hydraulic retention period of 240s. The advantages of this process over suspended growth systems such as the activated sludge process are indicated. The micro-organisms tentatively identified in the microbial film are tabulated.

The mechanism of cation exchange processes in the sorption of acridine by soil is also studied. Large differences in sorption were observed with cationic species much less readily sorbed than the neutral azaarenes. Partitioning appeared to be dominated by the mechanism of hydrophobic partitioning. Further data is necessary to assess hazards to groundwater from azaarenes in sludges disposed of in landfills.

Previous indications that power stations will have to rely on recirculating cooling systems are questioned, and a spatial linear programming method is proposed for evaluating the viability of alternative cooling systems. The application of the proposed decision model was tested with reference to water supply and demand balances in the Texas Gulf region for the years 2000, and 2030. Supplies of surface water and groundwater, potential transfers from irrigation and the use of sewage works effluent for cooling purposes were all considered. Contrary to previous assumptions, the model indicated that few potential benefits would accrue by the year 2000 from the development of advanced cooling systems as an alternative to direct water use, but that significant cost savings might be realised by the year 2030.

All three compounds partitioned predominantly into the solid phase. Partition coefficients for naphthalene ranged from 150 to 3630. Values for biphenyl and 2-methylnaphthalene were similar and 3-4 times higher than the value for naphthalene. Solids phase concentrations varied over a wide range and were not good predictors of concentrations in aqueous extracts. Predictions based on organic carbon partition coefficients and organic carbon content of the sludges seriously underestimated the partition coefficients but the oil content of the wastes and oil-water partitition coefficients appeared to be important factors in determining partition coefficients.

Experimental ponds AN - 13843992; 198500605 AB - Ten 15-m3 outdoor ponds were treated with unrefined coal oil for 8 weeks. At the lowest input rate (1 ml per m3 per day), temporary effects on cladoceran populations and ecosystem metabolism disappeared before the end of the oiling period. This exposure level, approximately 3 per cent of the 48-h LC50 in Daphnia magna, was considered safe for this ecosystem. The magnitude and duration of these effects increased as input rate increased (2 and 4 ml per m3 per day) and, at 8 and 16 ml per m3 per day, the pond community was completely disrupted. At the highest treatment level, this disruption persisted for more than a year. At all dosages, indirect effects included changes in water quality, changes in the abundance of some species and replacement of sensitive taxa by more tolerant competitors. These results were quantitatively and qualitatively similar to those of parallel experiments in pond-derived microcosms (see preceding abstract) .

Microcosms AN - 13840541; 198500604 AB - Sixteen 67-litre freshwater microcosms were treated with unrefined coal oil (0.03-7 ml per week) for 8 weeks. The average concentration of dissolved phenols, which constituted 95 per cent of the water solution compounds in the oil , ranged from less than 0.01 to 10 mg per litre. At the highest treatment level, damage was severe. Macrophytes, zooplankton and insects were eliminated and the ecosystems became anaerobic. The microcosms did not recover to pretreatment conditions within 5 months. At lower dosages, there were temporary effects on ecosystem metabolism, water chemistry and community structure. Measurable changes in community respiration, pH and cladoceran numbers occurred at phenol concentrations below those causing effects in the most sensitive single species test (the Daphnia magna 28-day reproduction bioassay).

For the coal-oil WSF, aniline and phenol, LC50 values ranged from 1.1 to 2.0 per cent, 287 to 442 mg per litre and 73 to 187 mg per litre respectively. The closer the taxonomic relationship between species, the more similar was the response to a given toxicant. Results suggest that the laboratory population may be representative of natural midge populations in bioassays.

Field testing involved the operation of large-scale lysimeters under controlled conditions containing municipal refuse and commercial waste (mainly from shops and restaurants), and leachate from these was applied to glass columns containing various types of industrial waste. The results were compared with laboratory studies designed to develop an extraction procedure simulating the behaviour of a landfill for combined disposal of municipal and industrial wastes. No one extraction procedure was capable of fulfilling all the necessary requirements although the use of carbonic acid in a rotary batch extraction procedure was representative of several conditions, and could form the basis of subsequent evaluations of biological toxicity.

Six in situ carbonate-precipitating treatments, varying the amounts of carbonate, alkaline earth cation (Ca or Ba as chlorides), and order of addition were examined for their ability to immobilize radiostrontium in laboratory soil columns. The Na (sub 2) CO (sub 3) - followed by CaCl (sub 2) -treatment was most consistently successful for reducing leachability of radiostrontium by 0.05 M CaCl (sub 2) from three low organic matter, acid soils, immobilizing as much as 53% of added radiostrontium. For the high organic matter, slightly acid soil, Na (sub 2) CO (sub 3) alone, without supplementary Ca or Ba, resulted in the best immobilization (39%); dissolution of soil organic matter and the alkalinity-induced aggregate dispersion probably interfered with CaCO (sub 3) and/or BaCO (sub 3) precipitation. Success of the treatments is based primarily on their ability to generate, in situ, Ca(Sr,Mg)CO (sub 3) or Ba(Ca,Mg,Sr)CO (sub 3) precipitates that exchange radiostrontium very slowly with eluting Ca ions. Allied tests with (super 137) Cs, which is commonly co-disposed with (super 90) Sr, indicated that the treatments described did not interfere with the natural tendency of the selected soils to fix (super 137) Cs strongly.

AN - 80971844; 6443880 AB - The (+) anti isomer of benz[a]pyrene diol epoxide (BPDE), 7 beta, 8 alpha-dihydroxy-9 alpha, 10 alpha-epoxy-7,8,9,10-tetrahydrobenz [a] pyrene has been identified as the probable tumorigenic lesion in mammalian systems. It forms a predominant adduct with DNA at N2 of guanine. In order to elucidate its conformation in atomic resolution detail, minimized conformational potential energy calculations were performed for the adduct with dCpdG. A global conformation search involving about 1000 trials was made. The lowest energy conformation had stacking between the hydrocarbon and the adjacent cytidine, in agreement with CD studies on modified GpU and UpG. This conformer differed from the B form most notably in the guanine glycosidic torsion, which is high anti. The next lowest energy form had torsion angles like the B form, with guanine-cytidine stacking. These two conformers differ in energy by only 2.1 kcal./mole, suggesting that their relative stability could easily be reversed in larger polymers, or under specific environmental conditions. Other conformations, with base-hydrocarbon or base-base stacking are also found, at somewhat higher energies. The Z form is at 7.8 kcal./mole. Thus, this adduct stabilizes the B form, in contrast with the N2 linked AAF adduct, which stabilizes the Z conformation.

This self-selection bias complicates efforts to estimate energy savings due to these programs. Several methods for dealing with self-selection are discussed, including nonrandom sampling of program nonparticipants, binary choice models that explicitly treat household decisions to participate & to retrofit, & use of both methods. Because some of the methods discussed are new & have not yet been applied to analysis of energy conservation programs, a synthetic data set is developed & numerical experiments are conducted with the data to examine the performance of different methods. The experiments show that the improved sample design & analytical techniques generally yield more accurate estimates of program energy savings. A small, well-defined synthetic data set is helpful in developing, debugging, & evaluating software associated with new analytical approaches. 5 Tables, 36 References. HA.

The amounts of cadmium, manganese, lead and zinc contributed by wet deposition only were compared and temporal and spatial trends examined. All metal concentrations were higher during warm weather periods; levels of cadmium and lead decreased during the later stages of the investigation, and also varied considerably between the sample sites. Manganese being principally soil-derived, exhibited no significant trends. Metal concentrations in the rainfall were negatively correlated with rainfall amount, owing to dilution of the wash-out.

Can It Be Explained? AN - 20803329; 10903341 AB - The widely held premise that providing people with information and education on emergencies, such as natural disasters, will reduce losses is examined in this article. The results of an empirical study to ascertain the relationship between information, education, and knowledge about adaptive responses in a threatening situation are presented. These results indicate a poor statistical relationship between knowledge and a number of explanatory factors suggested by previous research. The study indicates that the process of acquiring information on hazards is variable among individuals and poorly understood. Overall, the ways in which people learn about hazards appear to be as fragmented as existing policies to disseminate hazard information.

AN - 80343718; 11542751 AB - Recent results for neutron radiation-induced tumors are presented to illustrate the complexities of the dose-response curves for high-LET radiation. It is suggested that in order to derive an appropriate model for dose-response curves for the induction of tumors by high-LET radiation it is necessary to take into account dose distribution, cell killing and the susceptibility of the tissue under study. Preliminary results for the induction of Harderian gland tumors in mice exposed to various heavy ion beams are presented. The results suggest that the effectiveness of the heavy ion beams increases with increasing LET. The slopes of the dose-response curves for the different high-LET radiations decrease between 20 and 40 rads and therefore comparisons of the relative effectiveness should be made from data obtained at doses below about 20-30 rads.

The major purpose of the evaluation was to determine the energy savings attributable to the programs & to identify differences between program participants & nonparticipants. The sampling issues associated with reliable estimates of energy savings are explored. The methodology attempts to correct for the self-selection bias likely to occur in conservation program evaluation by using intentional nonrandom sampling. In addition, a variety of analytical approaches to analyzing the data with respect to energy savings are suggested. The proposed design, using four different groups to estimate program effects, is a comprehensive endeavor. This is appropriate for BPA because of the substantial investment it is making in conservation. However, the design is flexible & allows for use of fewer groups to reduce evaluation costs. 4 Tables, 1 Figure, 28 References. HA.

The only sex-linked difference was in the 'starved, 26C' group where males were more sensitive than females but it was noted that the mortality of controls on this regime was also higher in males.

Water was taken from a former low-level radioactive waste settling basin, filtered and treated with lime and/or magnesium carbonate and alum and/or ferric sulphate. This treatment removed uranium from moderately hard and soft raw waters if optimal pH (6 or 8) and dosage were used. A strong base anion-exchange resin was an effective retainer for uranyl carbonate complexes common in natural waters, though the required capital investment could be high.

The exploitation of these resources may require the consumption of non-renewable sources for their capture, storage and conversion, particularly when resource management is poor. The case of biomass is used to illustrate the argument and the degradation and depletion of soil and water as a result of the agricultural practices used in Arizona are described. The dilute and dispersed nature of natural energy sources necessitates the use of numerous large structures to harness them. The effect of uninhibited use of these resources could lead to unacceptable damage to ecosystems. JF - Environment International AU - Sharples, F E AD - Oak Ridge National Laboratory, Tenn.

Many of the effects were common to both, such as blockage of fish migration routes, water level fluctuations, inadequate streamflow, altered water quality, dredging and dredged material disposal and altered aquatic and terrestrial habitats. However, the impact from development of new sites was likely to be greater because at existing sites environmental changes had already taken place. The assessment of environmental impact was more difficult for new sites. Mitigation of adverse impacts by changes in design or operation depended on accurate predictions of environmental effects.

Seven algal species were tested for their responses to different organic chemicals in the presence of C-14 labelled bicarbonate ions. For most species the responses were pH-dependent, but for Selenastrum capricornutum the bioassay results were unaffected by pH in the range 7.0 to 9.0, by light intensity from 40 to 200 ueinsteins per m2 sec, culture density up to 0.5 mg chlorophyll a per litre, and agitation velocity up to 100 rev. per min. Assays could be performed in only 4 h, and the data suggest that algal photosynthesis is inhibited at levels of toxicant which are similar to those causing acute effects in aquatic animals. A model of a pelagic ecosystem is used to demonstrate that a temporary (7-day) inhibition of photosynthesis can have a measurable effect on other trophic levels, particularly if they are already subject to toxic stress.

The fraction of each year class killed was estimated. In the calculations estimates of abundance, mortality and period of vulnerability were used. Impingement probably reduced the 1974 year class by more than 20 per cent and 1975 by more than 15 per cent. However the analyses of the impingement collection rate suggest that it is not a reliable index of year class abundance in white perch. Even large changes in average year class abundance cannot be detected. Simple food chain and food web models were used to assess the effect of white perch impingement on other fish populations and suggested an increase in competitor fish species and in the abundance of young fish.

The analysis indicated that land resource issues should not constrain development of the fuel-ethanol industry, but the technology does pose some potential for water quality degradation. Several of the liquid process waste streams have high BOD and high levels of trace metals, but waste stablization ponds or other treatment techniques should be able to reduce water quality impacts to acceptable levels.

The results indicated that organic acids might play a major role in natural leaching processes in cold region soils undergoing podzolization. Nitric acid (from nitrification) dominated leaching in a nitrogen- fixing temperate deciduous site and carbonic acid dominated soil leaching in the tropical and temperate coniferous sites. Atmospheric inputs only played a major role in soil leaching at the temperate deciduous sites. Although further studies were necessary to verify these results, the methods used were considered sound.

Description and applications. AN - 80389364; 6821529 AB - A new model using xenotransplanted human epithelia was developed for the study of toxic and carcinogenic effects of chemicals. Epithelial cells from the respiratory tract of 4 male and 3 female premature and fullterm fetuses were enzymatically removed and inoculated into deepithelialized rat tracheas. These were sealed at both ends and transplanted subcutaneously into nude mice. After 3-4 weeks, a normal mucociliary epithelium covered the tracheal lumen. At this stage the epithelial cells could be isolated again and transplanted into new denuded rat tracheas. This passaging could be repeated up to six times, each permitting an amplification factor of approximately 3. Tracheal transplants containing cells of human origin (in vivo Passages 2-4) were treated with 7,12-dimethylbenz(a)anthracene. Hyperplasias, squamous metaplasias, and dysplasias were seen 1-8 weeks after initiation of treatment, indicating that the responses of human and rodent epithelial cells to polycyclic aromatic hydrocarbons are similar. Initial experiments with skin and esophageal epithelia suggest that other covering epithelia could also be used in this fashion for evaluation of toxicants and carcinogens that are likely to come into contact with these tissues.

The appearance and composition of these spheres strongly suggests that they are pseudomorphs after small pyrite framboids observed in the feed coal. The spinel particles and pyrite framboids exhibit nearly identical size distributions. Framboidal pyrite cannot be removed effectively from the coal by washing or magnetic separation because of its small particle size. It is a source of sulphur emissions and possibly a significant source of trace elements in the fly ash.

A large proportion of the body burden was found in the digestive system of fish and the body tissues of the snail. Concentration factors for the isotope were calculated and did not greatly exceed the values recommended by the U.S. EPA for the fish, though the snail values showed greater deviation. The potential exposure to technetium from nuclear facilities is considered sufficient to warrant further work on freshwater biota.

The fluidized particles consisted of anthracite graded to 30-60 mesh, supporting an attached biofilm. The reactor consisted of two cylindrical vessels in series, each 20 cm diameter and with a total height of 6.3 m. Tests were performed at nitrate concentrations from 100 to 15,000 mg per litre in the feed . Effluent nitrate concentrations increased over this range, but nitrite concentrations peaked sharply at a nitrate concentration of 4500 mg per litre in the feed . At higher feed concentrations the nitrite decomposition rate was an exponential function of the nitrate concentration. A model for nitrate removal was developed using Michaelis-Menten kinetics, and axial dispersion was shown to be negligible.

The reactor, developed by the Oak Ridge National Laboratory, consisted of a conical-bottom cylindrical steel tank packed with random 3 in diameter propylene Pall rings. A shell-and-tube heat exchanger in the feed line enabled the temperature of the incoming primary settled sewage to be raised to 25-30C. The reactor was inoculated with anaerobically digested sewage sludge from a nearby sludge treatment plant (Knoxville, Tenn.) and gas production, solids reduction and BOD removal monitored over a 9-month period at flow rates of up to 100 litres per min. Gas production rates of up to 1000 litres per day were achieved. The plant has provided design data for a full-scale bioreactor to be constructed at the site of the Loves Creek sewage treatment plant in Knoxville.

Nonvolatile organic constituents of the wastewater were identified. Membrane filter technique was used for total coliform counts. Changes in BOD, chemical oxygen demand, total organic carbon, total Kjeldahl nitrogen were studied. Chromatograms of irradiated and control samples were compared. After ultraviolet irradiation there was almost 100 per cent reduction in bacteria, whilst there were few chemical changes. However, the possibility of photoreactivation occurring needs to be studied further.

A key question concerns the actual energy savings that can be attributed to the program. Data were obtained from 59 Minn households that had received weatherization services & from 37 that had not. Comparisons of fuel consumption in the 2 groups for the 1976/77 & 1978/79 winters showed that the average savings due to weatherization was 13% of total household energy use. Based on 1979 fuel prices, the cost of weatherization is likely to be repaid with lower fuel bills in 3-4 years. 5 Tables. Modified HA.

Estimated annual fluxes were calculated from the rates of dry deposition on sample collectors and from analyses of rainfall. The results showed that both dry and wet deposition contributed significantly to the atmospheric flux of all four metals and that atmospheric sources were of major importance in the biogeochemical cycling of lead . Scanning electron microscope examination of leaf surfaces from the upper portion of the canopy revealed the presence of fly ash particles, which would be subjected to the leaching action of rainfall while in contact with the leaf surface, with the result that heavy metal concentrations may be two or three orders of magnitude greater than those in the rainfall alone.

Mean POC formation rate, expressed as DOC utilization, was about 0.2% of DOC per day and was primarily the result of microbial activity. When Ca super(2+) and Hg super(2+) were added to swamp water, and when swamp water and seawater were mixed, the rate of POC formation increased as a result of a rapid physiochemical flocculation process. Although the DOC load of rivers and streams of the southeastern U.S. represents a substantial energy input to estuarine regions, these results indicate that only about 25-30% of it is transformed through flocculation to a form more readily retained and utilized within the estuarine system. The remainder may be transported to the sea. JF - Limnology and Oceanography AU - Mulholland, Patrick J AD - Environmental Sciences Division Oak Ridge National Laboratory Oak Ridge, Tennessee 37830.

A Third View AN - 61064835; 81L7457 AB - Donald Lee has claimed ('Some Ethical Decision Criteria with Regard to Procreation,' Environmental Ethics, 1979, 1, 1, spring, 65-69) that of the three ethical values, freedom, justice, & security-survival, the last is the most important in population policy. As such, it should have priority over freedom & justice. Based on this hierarchy, Lee draws the conclusion that one does not have the right to unlimited procreation, & that ultimately it is the duty of government to impose limits on population growth. It is true that personal rights must be balanced by personal responsibility, but the fundamental ethical principle in the discussion should be justice. The substitution of justice for security-survival leads to two significant conclusions: (1) by focusing proper attention on justice, the threat of survival of the race from overpopulation is reduced to reasonable & realistic proportions; & (2) the recognition of the need for justice brings to light the fact that the primary responsibility of government is to address itself to redressing injustice in society, something that poses a very real threat to the survival of mankind. In that context, the government should under no circumstances have the right or the responsibility to enforce limits on procreation. Modified HA.

The development of evaluation plans for such programs can often be improved by reviewing evaluations that have been done on similar programs. The Residential Conservation Service (RCS), sponsored by DOE, is discussed as an example of how conducting metaevaluations can improve evaluation planning. Many utilities have sponsored programs that are similar to the RCS. A review of the utility program evaluations suggests key methodological issues & data problems that should be considered in the development of an RCS evaluation plan. The implications of these metaevaluation findings for an RCS evaluation plan are discussed. 2 Tables. HA.

During the past few years, both the overall efficiency of energy use & the number of government conservation programs have increased sharply. However, the extent to which these efficiency improvements were due to government programs is unclear. A key element in the careful evaluation of these conservation programs is data. Data, particularly on energy consumption, are needed to help sort out the effects of government programs relative to market forces. However, data can serve these purposes only if they are accurate, consistent, comprehensive, accessible, & documented. Data requirements & current data sources for careful evaluation of energy conservation programs are discussed. 2 Tables, 6 Figures, 28 References. HA.

Sub-lethal effects are caused, to Xenopus laevis embryos, which indicate that the environmental impact may be greater than that suggested by LC50 values. In particular, exposed larvae suffer severe ultrastructural cytological damage in the spinal cord and muscle.

Sampling was carried out at two stations during two floods, one winter and one spring , to determine concentrations of the various forms of N, P, Cl, Na, K, Ca, Mg, Fe, Mn, Si and Al; specific conductance, temperature and pH were also measured. The results presented show how during non-flood periods filterable concentrations generally exceeded particulate concentrations of most elements while during floods, the relationships between filterable and particulate fractions fall into three patterns, with the rising limb of the hydrograph especially important in the transport of certain elements.

It was found that the waters draining from surface soils and bog soils have a low pH (4.7 or less) because organic acids are present, while, in spite of the presence of organics, the ground water from mineral soils and stream waters were only slightly acid (pH 6). A worst-case model was used to project the possible effects of sulphuric acid, and demonstrated that, while acid rain would have little effect on near neutral waters, the pH of the most acid waters would decline significantly.

Daphnia reproduction was stimulated by acridine at no-observed-effect concentrations less than or equal to 0.4 mg per litre. The no-observed-effect concentration for acridine was approximately the same as those for chromium, atrazine and some surfactants. At concentrations immediately below those of the 48-hour LC50, acridine partially immobilizes D. magna . The results are considered useful in determining the potential environmental hazard to aquatic biota of releases of acridine in effluents from advanced fossil-fuel facilities.

It appears that sensitivity analysis has limited applicability for studying ecological interactions since large variations in measurements are usual. From the results with the model in this study it is suggested that the simple correlation coefficient derived from analysis of Monte Carlo simulations is a better way of ranking model parameters according to their prediction uncertainty.

The chlorinated effluents were then subjected to high-pressure liquid chromatography after 500 to 1500-fold concentration by low-temperature vacuum distillation. Subsequent detection and quantitation of the Cl-36 tagged organochlorine compounds was effected with the aid of liquid scintillation counters. In each HPLC separation, roughly 99 per cent or more of the Cl-36 activity was associated with the chloride ion, the residual 1 per cent being bound to stable organic molecules. A tentative identification of 17 chromatographic peaks for the chlorinated sewage effluent was achieved, while chlorination using either method gave essentially the same results. The yield of chlorinated organic compounds was more or less independent of chlorine dosage but increased with chlorine contact time. Some typical chlorine-substituted compounds identified in chlorinated sewage effluents and natural water samples are tabulated, including purines, pyrimidines, aromatic acids and phenols.

Acute toxicity to freshwater algae AN - 13889922; 198101519 AB - The acute toxicity to algae of the water-soluble fractions (WSF) of synthetic and petroleum oils have been compared. The materials tested were eleven coal liquefaction products, five shale oil products and six petroleum products. The acute toxicity of the WSF was assessed by measuring short-term photosynthetic inhibition of a green alga and a blue-green alga. The results indicate that coal liquefaction products are substantially more toxic to freshwater algae than are petroleum products, with shale oil products intermediate in toxicity. This implies a need for further research on the ecological hazards of synthetic fuels.

The sediment pH conditions markedly influenced the spectral characteristics of the dissolved humic materials. Organic-rich sediment selectively absorbed dissolved organic materials of high apparent molecular weight leaching from scenescing littoral vegetation during rain events, and slowly released materials of lower molecular weight between rain events. Sunlight caused rapid alteration in the spectral characteristics of the materials and influenced their seasonal regulation in shallow waters and in the upper photic zone in pelagial areas. Low levels of fulvic material were potent inhibitors of calcium carbonate precipitation by natural assemblages of algae, but did not alter the rates of carbon-14 assimilation over 3 days. Heavy rainfall may transport dissolved humic materials to pelagial areas lessening short-term epilimnetic losses of calcium carbonate: rainfall may thus both increase supplies of phosphate but retard coprecipitation losses of it in hard water lakes.

It is shown that the general Box & Jenkins method (Box, G. E. P. & Jenkins, G. M., "Some Statistical Aspects of Adaptive Optimization and Control," Journal of the Royal Statistical Society, 1962, 24, 293-343), when extended to allow for multiple interrupts, enables researchers simultaneously to examine changes in drift & level of a series, & to select the best fit model for the series. As applied to Ur renewal allocations, results show significant changes in the level of the series, corresponding to changes in party control of the executive. No support is given to the "incrementalism" hypotheses, as no significant changes in drift are found. 3 Tables, 1 Figure. HA.

Number of eggs per clutch and total clutch volume were inversely associated with measures of egg and naupliar size (egg volume, maximum egg length, naupliar volume, and maximum naupliar length). Thus, small clutches with large eggs give rise to large nauplii.

AN - 74995659; 11272114 AB - The rates of metabolism of the carcinogenic 2-hydroxybenzo[a]pyrene (2-OH-B[a]P) and the non-carcinogenic 3- and 9-hydroxybenzo[a]pyrenes in cultured cell systems have been studied and compared. While 70-80% of the non-carcinogens are converted to water-soluble derivatives by hamster embryo fibroblasts in 24 h, carcinogenic 2-OH-B[a]P is metabolized at a slower rate (45% in 24 h), comparable to that for the parent hydrocarbon, benzo[a]pyrene (B[a]P). Analysis of extracellular organic solvent-soluble metabolites of 2-OH-B[a]P in cultured hamster embryo fibroblasts, using h.p.l.c., indicates the presence of a single major metabolite, which has been identified by mass spectroscopy as a dihydroxy derivative of B[a]P. At least one additional major organic solvent-soluble metabolite is formed in cultures of either mouse epidermal epithelial cells or human foreskin fibroblasts, indicating a different balance of metabolic pathways in these cell systems. The greater persistence of carcinogenic 2-OH-B[a]P in cells and its higher concentration in the cell cytoplasm compared with the non-carcinogenic phenols may be related to its relatively high biological activity. Differences in metabolism of 2-OH-B[a]P in several cultured cell systems indicate the importance of an appropriate choice of activating system in understanding the relationship between metabolism and carcinogenesis.

AN - 74959125; 11272105 AB - Autoradiographic patterns of [3H]thymidine incorporation, nuclear/cytoplasmic ratios (N/C), and the percentage of dark epithelial cells were analyzed in a group of epithelial lesions induced by 7,12-dimethylbenz[a]anthracene (DMBA) in rat tracheal transplants. It was found that similar lesions of different age exhibit the same labeling indices (LIs), therefore the lesions of different age were subsequently pooled in the following groups and studied by high resolution light microscopic autoradiography: squamous metaplasia without or with only mild atypia, squamous metaplasia with moderate atypia, squamous metaplasia with severe atypia, carcinoma in situ, and microinvasive carcinoma. Normal tracheal and esophageal epithelia were also analyzed. Whereas the normal tracheal basal layer exhibited an LI smaller than 1%, a clear difference between the carcinomas (in situ and invasive) on one hand (LI approximately 32%) and all the remaining epithelia on the other hand (LI approximately 18%) was detected. The LIs of the suprabasal cells exhibited a statistically significant difference between the squamous epithelia without atypia (LI approximately 2%) and the group comprising all the atypical lesions (LI approximately 9%). Gradients of increasing N/C (nucleus-cytoplasm ratios) values could be observed as the lesions increased in severity, especially in the middle and surface layers (e.g., in the surface layer regular metaplasia N/C = 0.08, squamous metaplasia with moderate atypia N/C = 0.26, and carcinoma in situ N/C = 0.50). Dark cells were absent in the normal esophageal epithelium, were present in moderate numbers in the basal layer of regular squamous metaplasia (18%), and increased markedly in the atypical epithelial lesions (approximately 50% in the atypical squamous metaplasias and 70% in carcinoma in situ). In the suprabasal layer dark cells increased from 3% in squamous metaplasia with moderate atypia to 28% in metaplasia with severe atypia and 56% in carcinoma in situ. The results confirm in a quantitative fashion that disturbances of cell maturation and cell proliferation are key features of dysplastic lesions induced by chemical carcinogens, and suggest the use of objective parameters for evaluation and classification of preneoplastic alterations.

This man-made reservoir, surface area 10.5 ha, formerly received chronic inputs of chromates from cooling towers with typical blowdown concentrations in the range 3-10 mg per litre. Results indicate that chromium levels in muscle and whole body of most species analysed may be inversely related to fish weight. There were no significant differences in chromium levels in different fish species, with the exception of goldfish. There was also no difference in chromium concentration in muscle of bluegill and largemouth bass from the contaminated lake and from a neighbouring, uncontaminated reservozr.

The sewage was fed in at the base of the column and steady-state conditions maintained for extended periods in order to evaluate column removal rates for BOD and total suspended solids at constant hydraulic loading, and also the quantity and composition of the gas removed under pressure from the top of the column. Column effluent was treated by chemical coagulation or dual media filtration, in attempts to reduce final suspended solids and BOD to acceptable levels for secondary effluent. Cost breakdowns are presented in respect of total treatment systems operating on the packed column principle which are claimed to show significant cost and energy savings relative to conventional processes.

A comparison of observed and predicted bioconcentration of azaarenes in the fathead minnow (Pimephales promelas) AN - 13901377; S198104201 AB - The actual bioconcentration of the nitrogen-containing polycyclic aromatic azaarenes, some of which are carcinogenic, by the fathead minnow has been compared with predictions based on octanol/water partitioning and with measures of their bioconcentration in Daphnia pulex. The results indicate that lipophilicity plays a greater role in determining the bioconcentration in Daphnia than it does in the fish. Thus the bioconcentration observed in the minnows was found to be about 1000-fold lower than the predicted values or those observed in Daphnia. Metabolic alterations to azaarenes in fish are fast enough to play a large role in determining bioconcentration of organic compounds.

Several types of contacting device were evaluated, including shaken flasks, stirred vessels and countercurrent columns. The culture was assessed for the rate of uranium uptake and the equilibrium distribution between the cell and solvent phases. Saturation of the biomass with respect to uranium was achieved at a concentration of about 0.14 gU per g cell dry matter, a value in excess of those previously reported for several alternative adsorbents. Equilibrium was reached in about 15 min and using the countercurrent system, the uranium concentration could be reduced from 25 to 0.5 gU per m3 with a mean residence time of 8 min.

The test materials comprised seventeen solid waste products, and an arsenic-contaminated ground water, in order to identify the potential hazards created by the presence of leachate in crop irrigation systems. The official extraction procedure was inadequate as a means of reflecting the presence of organic compounds in the leachate, the extracts being predominantly ionic in character, and an alternative procedure designed to identify possibly harmful organic contaminants is proposed. Methods for chemical analysis, aquatic toxicity, phytotoxicity and mutagenicity testing are also discussed. JF - U.S. Environmental Protection Agency.

The thermal emission isotope dilution technique, in which an anion exchange resin bead was used to concentrate the plutonium and uranium, provided technical information on samples of orders of magnitude smaller than those necessary for conventional counting techniques.

I. A water budget model AN - 13893266; 198100950 AB - A water budget model was developed from field studies of a marsh in Wisconsin, U.S.A. The model is a set of simultaneous differential equations that are numerically integrated. The fundamental equation is based on conservation of mass per unit area in terms of run-off rate, precipitation , deep ground water input, evapotranspiration and shallow ground water and surface water discharge. As each component of the model is described, pertinent field results are presented and related to model parameters. The water budget is estimated for computation of phosphorus loading to a neighbouring lake. The model was used to estimate the water table elevation at an observation well where direct measurements were taken and shown to provide an adequate computation of the water budget.

The possibility of interference due to some feature of the extraction process was confirmed; acetic acid used in the aqueous extraction procedure had an inhibitory effect in the aquatic toxicity and phytotoxicity tests. The results could also be affected by the inability of this method to extract non-polar organic compounds, coupled with the possible adsorption of these compounds on the filter membrane employed in the standard EPA extraction method.

Short-term acute toxicity bioassays were performed using Daphnia magna, while mutagenicity tests were based on the Ames Salmonella histidine reversion system. Tests were employed on various fractions from raw and treated wastewaters, obtained by conventional chemical fractionation methods. The major mutagenic activity was in the basic and neutral fractions, such as tars and sludges generated by acid precipitation . Toxicity of the untreated waste was predominantly due to the organic components, but as these were degraded, toxic reaction products began to appear. The results suggest that a large reduction in the original contaminant level may not necessarily produce an effluent of low toxicity, while variations in process operating conditions may also influence the end result.

The software is designed to quantify and automatically map geologic and other cost-related parameters as required to estimate coal mining costs. The software complements the detailed coal production cost models for both underground and surface mines which have been developed for the Electric Power Research Institute (EPRI) by NUS, Corp. These models require input variables such as coal seam thickness, coal seam depth, surface slope, etc., to estimate mining costs. This report provides a general overview of the software and methodology developed by ORNL to calculate some of these parameters along with sample map output which indicate the geographical distribution of these geologic characteristics. A detailed user guide for implementing the software has been prepared and is included in the appendixes. (Sample input data which may be used to verify the operation of the software are available from ORNL.) Also included is a brief review of coal production, coal recovery, and coal resource calculation studies. This system will be useful to utilities and coal mine operators alike in estimating costs through comprehensive assessment before mining takes place.

The reactor consisted of a 5 ft diameter cylindrical fibreglass tank containing a 10 ft depth of packing composed of 1 in ceramic Raschig rings. Comminuted sewage was pumped to a header tank from which it was fed by gravity to the base of the column. A conical bottom with a gate valve underneath the column permitted removal of settled solids at periodic intervals. influent BOD values ranged from 60 to 200 ppm, with effluent BOD fluctuating principally between 50 and 100 ppm. The effects of operating variables on BOD removal rates were investigated, and tentative designs for scaled-up versions treating up to 1 million U.S. gal per day of crude sewage were prepared.

In all cases, the average length of fish in each group increased linearly with time, t, in a range from 10 to 30 mm. The variances about these mean lengths increased approximately as t super(2). A partial differential equation model can be useful in expressing the dynamics of populations in which size distributions are taken into consideration. Applied to our experiment, this type of model shows that both of the observed length-versus-time phenomena are expected if the rates of increase of length of fish are independent of length and that these rates for individual fish are normally distributed about some mean rate of growth. The variance of individual growth rates needed to produce the observed length- versus-time data can be calculated from the model.

Eight litres of the effluent were used to prepare acid, basic and neutral organic fractions, while the inorganic fraction was separately extracted from one litre of effluent. Acute toxicity tests were performed on the resulting fractions using Daphnia magna as the test organism. The toxicities of the fractions differed quantitatively and qualitatively but their combined effects were simply additive. JF - Aquatic Toxicology.

Equilibrium constants for the processes of sorption and bioaccumulation were also determined. The results indicated that photolysis and microbial degradation within the water column were likely to be the dominant pathways of anthracene elimination from aquatic systems. However more work is required to determine the extent to which degradation rates for anthracene are representative of other PAH. JF - Aquatic Toxicology.

Since the exposure period for a developing egg is limited by hatching, the larval stage becomes more sensitive when exposure is extended. Thus, for an acute short term release of nickel the egg would be the more crucial stage, but for a long term chronic release the toxicity of nickel to the larval stage would be more crucial to the survival of a popuLation.

Fathead minnows were exposed to 100 ug acridine per litre in spring water in a flow-through system, to sediment contaminated with 113 ug acridine per g, fed on contaminated zooplankton and fed on benthic invertebrates living in contaminated sediments. The uptake kinetics from water were estimated using a simple uptake elimination model, and the overall accumulation via four pathways was described by a conceptualized expression. Results showed rapid accumulation directly from water at 1.4 ug per g hour while from sediment and invertebrates the rates were 0.02 and 0.01 ug per g hour respectively. From zooplankton the uptake rate was only 0.006 ug per g hour.

AN - 74483769; 400973 AB - A general methodology of predicting the food chain transport of atmospherically deposited radionuclides is reviewed with an emphasis on variation in parameter values important for realistic behavioral characterization of environmental releases of plutonium, uranium, and thorium. Parameters important to generic simulations of food chain transport, given a known constant deposition onto vegetation, include: fractional interception of particulates by vegetation, vegetation density, effective half-life of contamination on vegetation, soil-to-plant transfer factors, consumption rates by cattle and man, and transfer of nuclides from forage to meat and from forage to milk. Variation in these parameters, which has been encountered in field studies, is summarized. A partial reduction in the variation of predicted concentrations of actinides in foods can be accomplished by more accurately determining critical parameter values like fractional interception of deposition by vegetation, vegetation biomass, and the effective half-life of contamination on vegetation. Field research describing the site dependency and time dependency of probability density functions for model parameter values is needed to make probabilistic predictions concerning Pu, U, and Th transport in food chains and to reduce the uncertainty associated with model predictions and generic assessments of environmental impact.

The concentrations of inorganic and methylated mercury (MeHg) in several organs of control and test fish were periodically measured over this 50-wk period. The inorganic mercury levels in test fish increased rapidly during exposure. The MeHg concentrations in both control and test fish increased slowly and at the same rate, with final 350-day concentrations comparable to levels found in wild brook trout from an uncontaminated area. This information indicates that fish do not methylate inorganic mercury in vivo, and that approximately one-half of the MeHg body burdens in the fish was acquired via the food.

The influence of water temperature, light available for photosynthesis, nitrate nitrogen, and total phosphorus on species-specific variation in photosynthetic activity was analyzed by stepwise multiple regression. Declining phytoplankton populations in Lake Tahoe were precipitated by an unfavorable change in the physico-chemical environment rather than by zooplankton grazing, since in all three cases population reduction followed declining photosynthetic activity. Data also support the overriding influence of nitrate nitrogen over phosphorus as a limiting nutrient in Lake Tahoe. Of the four parameters, water temperatures was the most ciritcal affecting photosynthetic rate at 50 m of Stephanodiscus astraea, while nitrate nitrogen was the most important for Cyclotella stelligera, and to a lesser extent Fragilaria crotonensis. For all three species temperature correlated inversely with photosynthetic activity. Algal samples were injected with carbon-14 sodium bicarbonate solution with an activity of 9.2 microCi/ml. Incubated and filtered samples were packaged with Kodak AR10 Autoradiographic Stripping Plates and exposed for 3-6 weeks; five proved optimal. Results were evaluated according to silver grain density.

It is shown that this function may be readily incorporated into the age-specific probability of survival in a Leslie-matrix population model. A method is presented for indirectly determining the probability of survival for age-class 0 of a fish population using a density-dependent Leslie matrix. The method involves the two constraints that the population be at equilibrium and that the index of absolute population size in the density-dependent function be assigned a value. In addition, given the probability of survival for age-class 0, it is shown that the probability of survival through a selected life stage within age-class 0 can be indirectly determined. Three problems in modeling a fish population using a Leslie model are discussed in light of the difficulties involved in modeling density dependence due to insufficient information and lack of understanding concerning density- dependent phenomena.

AN - 733445924; 16345270 AB - To determine rates of microbial transformation of polycyclic aromatic hydrocarbons (PAH) in freshwater sediments, C-labeled PAH were incubated with samples from both pristine and petroleum-contaminated streams. Evolved CO(2) was trapped in KOH, unaltered PAH and polar metabolic intermediate fractions were quantitated after sediment extraction and column chromatography, and bound cellular C was measured in sediment residues. Large fractions of C were incorporated into microbial cellular material; therefore, measurement of rates of CO(2) evolution alone would seriously underestimate transformation rates of [C]naphthalene and [C]anthracene. PAH compound turnover times in petroleum-contaminated sediment increased from 7.1 h for naphthalene to 400 h for anthracene, 10,000 h for benz(a)anthracene, and more than 30,000 h for benz(a)pyrene. Turnover times in uncontaminated stream sediment were 10 to 400 times greater than in contaminated samples, while absolute rates of PAH transformation (micrograms of PAH per gram of sediment per hour) were 3,000 to 125,000 times greater in contaminated sediment. The data indicate that four- and five-ring PAH compounds, several of which are carcinogenic, may persist even in sediments that have received chronic PAH inputs and that support microbial populations capable of transforming two- and three-ring PAH compounds.

Fish acclimated to 15 C and exposed to temperatures cooling 1 C each 72 hours decreased in feeding activity and schooled less compactly beginning at 9 C. At lower temperatures they lost orientation and were insensitive to external stimuli, and none survived exposure to 4 C. Threadfin shad exposed to sudden cooling (2 to 5 C decreases in 4 hours) lost equilibrium in proportion to the magnitude of temperature decrease if minima of 4 to 6 C were reached. Cold-shocked fish that had lost equilibrium for 0.2, 30, and 90 minutes before being returned to warmer water experienced mortalities of 32, 79, and 94%, respectively.

The second deals with actual samples from existing or experimental processes. A 'tier system' of testing was used including liquid-liquid extraction and column chromatography and a number of living organisms. Results implicate chemicals occurring in the basic (ether-soluble) and the neutral fractions of oil-shale and coal conversion effluent as potential genetic hazards.

Significant changes in the UV absorption were identified as a result of treatment by all three methods, especially chlorination and ozonation which destroy volatile constituents and produce non-volatile ones. Disinfection with UV radiation however had relatively little effect on the non-volatile organic compounds. JF - Progress in Wastewater Disinfection Technology.

Results are presented for treated and untreated samples from numerous treatment plants. Mutagenicity was detected in a number of raw and chlorinated effluent samples; a concentrate of one such sample was subjected to high-performance liquid chromatography and four successive cuts were also tested similarly. Positive reactions were obtained from two out of the four fractions but their combined activity was far less than in the sample prior to chromatography, suggesting the possibility of inactivation on the column.

The methods employed for sampling, determination of total PAH content and identification of specific PAH components are described. There was some degree of selective partitioning of individual PAH compounds between the sediment and the water column, with fluoranthene as the major sediment PAH, and pyrene as the major water PAH. Other differences between the PAH content of water and sediments were indicative of a selective sorption of a certain class of PAH or of their persistence in the sediment. Several cocarcinogens and carcinogens were found in the sediment, including bioactive compounds not reported previously, notably benzo(c)phenanthrene , benzofluoranthene, and o- phenylenepyrene. Sediment in the wastewater channel contained 22 times more PAH than that from a control site upstream, but concentrations decreased rapidly downstream reaching the control level about 0.6 Km below the discharge point. There were, however, further sources of PAH and each source produced its own characteristic spectrum of PAH, with accumulations in the sediment especially in the immediate vicinity of the discharge.

Ether-soluble base (ESB) fractions of several crude oils and refinery effluents exhibited high levels of activity in the Ames microbial screening test for mutagenic activity. A further two-step subfractionation procedure was devised using liquid chromatography with alumina and Sephadex LH-20 columns in series, constructed by modifying standard burettes. Mass balance calculations indicated quantitative recoveries of the ESB components, with almost quantitative recovery of biological activity. Gas chromatography coupled with mass spectrometry demonstrated that the principal constituents of the highly mutagenic subfraction were azaarenes such as azabenzoperylenes, azaindopyrenes and azacoronenes. Confirmation of the mutagenic activity of the pure compounds is available. JF - American Chemical Society.

They were dosed with 14C-labelled samples of several polycyclic aromatic hydrocarbons and incubated at 22C; autoclaved samples served as controls. Measurements of 14CO2 evolution confirmed that the decomposition of anthracene, benzanthracene and benzpyrene proceeded more rapidly than had been observed in previous studies of either pristine or petroleum-contaminated watercourses. At all locations 14CO2 evolution from benzanthracene was roughly 50 times that from previously-assayed petroleum-contaminated sediments, and evolution of 14CO2 from 14C-labelled benzopyrene reached 0.2 per cent of the total 14C added within 24 hours of incubation. No 14CO2 was evolved from samples dosed with dibenzanthracene or dimethylbenzanthracene, but microbial decomposition products from these compounds could be detected by thin-layer chromatographic separation.

By the application of nitrate the growth of indigenous bacteria was encouraged, leading to an increase in the rate of decomposition of plant detritus. The effects of irrigation at rates of 50-200 kg per ha year confirmed the influence of nitrogen on the rate of decay, and a linear compartment model was used to predict the acceptable duration of long-term treatment taking into account the changes in the carbon-nitrogen ratio and the associated effects on the forest carbon and nitrogen cycles.

The model was developed for simulating the transport of toxic substances through an ecosystem comprising the atmosphere, land surface, vegetation, soil layers, ground water and streams. The Wisconsin Hydrologic Transport Model was shown to be capable of predicting heavy metal contents of surface waters following storm events. An alternative version: Terrestrial Hydrology and Ecology Model was more appropriate for predicting the uptake of heavy metals by crops and vegetation, following sludge or waste disposal by landspreading.

Movement over an 11-week observation period was longshore and oblique to the ridge crest at the experimental site. Currents were also predominately longshore, but long term averages demonstrate that a vertical shear existed in the fluid motion. Although the number of sediment transport "events" suggested by the current meter data is nearly balanced in eastward and westward directions, both estimates of transport from current speeds and sand tracer dispersion patterns show that several westward flowing events dominated the transport during a two and one-half month period. A quantitative upper bound of 31 cm/sec on the threshold velocity for sediment movement in this size range is also set by the data.

After 10 years, the stream remained devoid of fish for at least 8 km downstream from the fill. The downstream water had a pH of 4.5 to 5.9; upstream from the fill the pH was 6.5 to 7.0. The rock material in the fill contains iron sulfide minerals. Other streams in the area flowing on the sulfide-rich rocks also showed low pH values. Survivability tests and stream surveys showed that brook trout cannot tolerate conditions in the stream below the road fill or in a stream flowing over natural outcrops of the same rock used in construction of the road fill. Native salamanders were also adversely affected downstream from the road fill. Chemical analyses of stream water and leaching tests indicated that lowered pH and increased sulfate and metals concentrations derived from the leaching of the sulfide-rich rocks were responsible for the trout and salamander mortalities.

Hawkes's "Spatial Patterning of Urban Population Characteristics" AN - 60909036; 75H6350 AB - In response to R. K. Hawkes (see SA 22:1/74G6721) comments are made on: "(1) Hawkes's choice of functions, particularly the unjustified limitations he has placed on the radial function; (2) the conflict between Hawkes's assumption of a city center as a single point of dominance & evidence in dicating multiple centers; & (3) the general problem of subdivision of an area & its relationship to continuity of the surface representing a distribution of a characteristic of the area." In REPLY TO CARSTEN HAALAND'S COMMENT, Roland K. Hawkes (Southern Illinois U, Carbondale), states that since he was studying percentages not density, an exponential function was not necessary. Haaland has misunderstood the term "center of dominance." Haaland's criticisms perhaps are due to misunderstandings. 2 Figures. L. DeForge.

The procedure is to construct a paradigm showing national trends in the relationship of population & employment, then to compare it to data for the 'Old Manufacturint Belt' (OMB) & the South to determine if the processes at a national level are apparent in different subnational levels. The paradigm includes information showing the development of the US LF according to type of industry 1870-1970, the factors underlying the process of urbanization, & the dispersion of population & economic activity within metropolitan areas. If population redistribution & economic diversification & dispersion occur simultaneously (as indicated by the national paradigm), employment in the more urbanized OMB will be more dispersed than that in the South, but over time, economic activity in the South will show a trend toward greater diversification. The findings support the proposition. Throughout, the paradigm is shown as a useful model for indicating broad patterns of change. 5 Tables, 2 Figures. Modified HA.

Laboratory experiments revealed high mortality and no reproduction in cultures of D. clavipes in which P. foliosus was allowed to float free, with no significant changes from controls when vegetation was restricted to a small area. Inclusion of simulated rooted aquatics (polyethylene tubing) lowered the reproductive rate below that in cultures without tubing. These . results suggest that P. foliosus is important in regulating both distribution and density of D. clavipes in the pond.

K. Whelpton, A. A. Campbell & J. E. Patterson, FERTILITY AND FAMILY PLANNING IN THE UNITED STATES, Princeton: 1966) was that whites & blacks without southern Ru experience had similar fertility. This study reports on a re-examination of this finding with a substantially larger black sample. Data from the 1967 Survey of Econ Opportunity demonstrated that the residence background classification utilized in the GAF study defeated, in part, the attempt to remove the effects of Ru experience on fertility. Indigenous Ur blacks had 25% higher fertility than indigenous Ur whites. The fertility of Ur black migrants out of the Ru South was sharply curtailed in contrast to those remaining in the Ru South. Although Ur blacks of southern Ru background had nominally higher fertility than indigenous Ur blacks, the diff was neither statistically nor substantively signif. These results demand a reordering of the interpretation of the impact that migration has on Ur black fertility & the white-black diff'ial in fertility. Modified HA.

AN - 84458239; 11817410 AB - Since the interaction of the parasitic wasp Habrobracon with the space environment could not be prejudged, we decided to test approximately 30 different parameters of a genetic, mutational, biochemical, behavioral, and physiological character in the one spaceflight we had at our disposal. These parameters were examined at six different exposures of gamma-radiation (including 0 dose) in flight, resulting in about 180 different endpoints in all. The most profound effects of spaceflight in conjunction with radiation were decreased hatchability and enhanced fecundity of eggs exposed to spaceflight at different stages of oogenesis. The interpretation we favor is that these two endpoints are reflections of chromosomal non-disjunction in the former case and inhibition of cell division in the latter. Our most comprehensive study of mutagenesis was on sperm, where dominant lethality, recessive lethality, translocations, and visible mutations were assayed; the only effect found was a threefold enhancement of the recessive lethal mutation frequency in the non-irradiated sperm in the orbited Habrobracon males. Behavioral and biochemical differences were found. Mating activity of orbited males was severely disrupted and xanthine dehydrogenase activity was sharply decreased in the irradiated flight animals, an unexpected observation. Postflight experiments were like the ground-based control experiments in all aspects but one. Under conditions of vibration similar to those encountered during the launch and re-entry, the mutation frequency in the sperm increased by a factor of three over that of the non-vibrated control.

AN - 85138059; 11949689 AB - Genetic effects associated with space flight include mutation induction by the space flight itself, and enhancements or antagonisms of radiation-induced mutations. The conditions of space flight vary in mutagenic effectiveness from no response at all to responses nine times that found in ground-based controls. The test systems follow the sensitivity pattern: spermatogonial translocations > oogonial and oocyte nondisjunction > recessive lethality of stages in spermatogenesis > dominant lethality of stages in spermatogenesis. Large enhancing and antagonistic effects of space flight in conjunction with radiation were observed in the Biosatellite II experiment. The most surprising one was the elimination of the effect of 2500 R by space flight in Habrobracon oogonia where the effects of 500 R normally can be easily observed. Two sets of parameters are considered in attempts to explain the responses: (1) the nature of the biological targets, and (2) the particular conditions of space flight that are responsible for the effects.

AN - 85136319; 11949688 AB - The results of recent experiments with the lysogenic bacteria, Escherichia coli and Salmonella typhimurium, the bread mold Neurospora crassa and the flowering plant Tradescantia on the Biosatellite II and Gemini XI Missions will be summarized. In the lysogenic bacteria experiment (Dr. Rudolf H.T. Mattoni, NUS Corporation) on the Biosatellite II mission significant effects of space flight were found on both growth rate and the induction of prophage. In that part of the Neurospora experiment on both the Biosatellite II and Gemini XI Missions (Dr. J.F. de Serres), utilizing non-dividing and inactive spores, no difference was found in the genetic effects of radiation between the flight and ground samples. In that portion of the Neurospora experiment on the Gemini XI mission utilizing rapidly-metabolizing spores the genetic effects of radiation were less serious in the flight samples than the ground samples. In the Tradescantia experiment (Dr. A.H. Sparrow, Brookhaven National Laboratory) on the Biosatellite II Mission, the irradiated flight material, in general, produced increased rates of cell death, abortion of pollen, loss of reproductive integrity, as well as other abnormalities in cell structure and function. In some of the experiments there were found significantly genetic effects of space flight alone, and the enhancement of various genetic effects of radiation under weightlessness was no more than 2- or 3-fold.

The method is flexible in yielding average values over a treatment set established by experimental design. Specimen data on in situ populations of Skeletonema costatum are examined for illustration. Changes in estimated energy-processing characteristics of this diatom during a summer succession in the York River, Virginia, indicated a wide range of physiological states available to the species. Computed values of its gross production and respiration were correlated positively, but estimates of its productive output per individual were related inversely to corresponding values for other species. Various usages of the technique are discussed. JF - Limnology and Oceanography AU - Patten, Bernard C AU - Van Dyne, George M AD - Oak Ridge National Laboratory, 3 Oak Ridge, Tennessee 37830.

AN - 84823505; 18623923 AB - Human peripheral lymphocytes from tumor-bearing and non-tumor-bearing patients were added to monolayer cultures of autochthonous and allogeneic normal or neoplastic cells in vitro with or without phytohemagglutinin (PHA). The normal cells were derived from skin, the tumor cells from postnasal carcinomas or sarcomas. The cultures were scored for clearly visible plaques in the monolayer. Without PHA, lymphocytes affected autochthonous skin target cells in 1 of 16 cultures. If PHA was added,the figure increased to nearly 50%(12/28). Whether this phenomenon is related to an autoimmune reaction or to some less specific effect of the PHA stimulus is unknown at present. In the absence of PHA, lymphocytes from African tumor-bearing hosts destroyed allogeneic skin fibroblasts in 4 of 14 cases, and lymphocytes from non-tumor-bearing Swedish donors showed this effect in 14 of 24 tests. The somewhat lower reactivity of the African lymphocytes was also apparent in other tests. It cannot be stated whether the difference was due to the tumor-bearing condition of the hosts or to some other differences involved in comparison of the two groups. Without PHA, lymphocytes of the African tumor patients destroyed their own autochthonous tumor cultures in 4 of 16 cases. Addition of PHA increased the proportion of positives to 20 of 28. A comparison with the corresponding figures for autochthonous skin cultures (1/16 and 12/28, respectively) indicates a relatively higher reactivity against the autochthonous tumor cells, both with and without PHA. This cannot be interpreted as a difference in target cell sensitivity to the same lymphocyte action, because no such difference was apparent when the sensitivity of skin and tumor to allogeneic lymphocytes was compared in the absence of PHA (4/14 and 4/14 with African lymphocyte donors; 14/24 and 14/24 with Swedish lymphocyte donors, respectively). The most probable explanation is that the antigenic barrier responsible for the lymphocyte effect is larger for tumor than for skin, or that the results reflect a presensitization of the tumor donor against its autochthonous neoplastic cells.

The amount of super(137)Cs that must be ingested to maintain the equilibrium body burden of the carp was calculated from measured values for body burden, biological elimination rates, and assimilation factors. The radioisotope was ingested by the fish as an integral part of its food items. The amount of food consumed was estimated by measuring the concentration of super(137)Cs in the food items. An age and growth study and the weight-length relationship are given for the carp. The estimate of the average daily food intake was 5.36 g wet weight (3.9% of mean body weight) consisting of 2.4 g detritus and 1.6 g algae for maintenance, and 0.82 g detritus and 0.54 g algae for growth. On an energy basis, 3.7 kcal were consumed for maintenance and 1.3 kcal for growth. Net and gross food conversion factors were 3.18 and 12.55, respectively, and the ecological growth efficiency was 0.08.

The instantaneous growth rate, calculated from the growth curve of periphyton on plates in the streams, was 0.51 g m super(-2) day super(-1) as compared to an estimate of 0.60 g m super(-2) day super(-1) obtained by oxygen measurements for growth of periphyton on the stream bottom. The average growth rate of periphyton on plates in the streams over a single exposure period was 0.31 g m super(-2) day super(-1). Under the conditions of this experiment, the instantaneous growth rate was a better estimate of productivity than the average growth rate.

RUTHENIUM-106 (1038 C) AND CESIUM-137 (704 C) ACCOUNT FOR MORE THAN 90% OF THE TOTAL ACTIVITY NOW PRESENT AT THE SITE, WHILE CO-60 (152 C), THE RARE EARTHS (17 C, EXCLUSIVE OF Y-90), AND SR-90 (15 C) MAKE UP THE REMAINDER. MORE THAN HALF OF THE ACTIVITY IS ASSOCIATED WITH THE UPPER 6-IN. SEDIMENT LAYER, WHILE PROGRESSIVELY SMALLER QUANTITIES OF ACTIVITY ARE FOUND WITH DEPTH. THE RUTHENIUM, WHICH IS RESTRICTED TO A SMALL AREA IN THE AREA IN THE NOW DRY UPPER LAKE BED, IS PARTIALLY WATER SOLUBLE; HOWEVER, ITS RATE OF MOVEMENT THROUGH THE SOIL IS SLOW ENOUGH SO THAT RADIOACTIVE DECAY REDUCES THE CONCENTRATION OF THAT REACHING SURFACE STREAMS TO INSIGNIFICANT LEVELS. MOST OF THE CS-137 OCCUPIES HIGHLY SELECTIVE EXCHANGE SITES ON THE ILLITIC FRACTION OF THE CLAY IN THE SEDIMENT AND CAN BE DESORBED ONLY BY DISRUPTION OF THE LATTICE STRUCTURE. ONLY A SMALL FRACTION OF THE CO-60 IN THE SOIL WAS FOUND TO BE EXCHANGEABLE. IT IS, THEREFORE, UNLIKELY THAT ANY LARGE FRACTION OF THE CS-137 OR CO-60 WOULD MOVE FROM THE AREA EXCEPT THROUGH EROSION OF THE SEDIMENT. ABOUT ONE-HALF OF THE SR-90 AND THE RARE EARTHS IN THE SEDIMENT APPEARS TO BE EXCHANGEABLE, WHILE THE OTHER HALF IS IN THE FORM OF SLIGHTLY SOLUBLE SALTS. THROUGH LEACHING BY GROUNDWATER, A SLOW DEPLETION OF STRONTIUM FROM THE DRY PART OF THE LAKE BED OCCURS. (HOUSER-ORNL) JF - HEALTH PHYSICS, VOL 11, NO 6, P 567-577, JUNE 1965. 5 FIG, 3 TAB, 10 REF.

It is claimed that sci as a whole is a misleading classification & that, in considering justification for sci's claim to support, applied sci-done to achieve some nonsci'fic goal-should be viewed as part of the effort to achieve that goal & should therefore be supported as part of that effort. The claim of the remainder of sci to society's support can be based either on its cultural value or on its function as a necessary overhead on the whole applied sci'fic enterprise. It is asserted that basic sci as 'sci'fic overhead' is a more valid basis for public support than 'sci as culture', at least until the society that is asked to support basic sci understands enough basic sci to appreciate it as culture.

(2) Is Big Sci ruining the US financially? & (3) Should we divert a larger part of our effort toward sci'fic issues which bear more directly on human well-being than do manned space travel or high-energy physics? In answering the 1st question, the author claims to see evidence that Bigness is imposing on sci a journalistic flavor; that preoccup with spending money & with administration is leaving sci'ts with less time to spend on thought. As for the financial burden caused by the growth of sci, expenditures on sci will finally have to be set at a fixed fraction - perhaps 1% - of the Gross Nat'l Product; the present unlimited growth cannot continue forever. The decision to go all-out on man-in-space is criticized, both on technical & philosophic grounds. There are many examples in history of societies which have allowed their nat'l purposes to be diverted to irrelevancies & have failed as a result. AA.

These intercensal population data incorporate estimates of population change based on vital statistics (natural change) and administrative records (migration). However, these population estimates do not account for disparate growth patterns at the local or census block level. Allocation of the intercensal population change is one of the many factors considered in the LandScan modeling process by which existing census data are updated and re-distributed to high-resolution cells in the LandScan USA population database. A simple prorating of the intercensal growth across a county adds proportionally more people to the blocks containing the greatest population (thus adding more people to blocks that may already be fully developed). Previous algorithms (LandScan USA v1.0) attempted to mitigate this shortcoming by identifying county growth areas by calculating census tract population change between 1990 and 2000, taking into account that sometimes tract boundaries mismatch between the two Census years. The tract percentage change was prorated to the blocks within each tract and normalized to the intercensal county estimate. This process assumes that the areas of a county that were experiencing growth in the preceding decade would continue to grow (or decrease) at a predictable rate. To overcome these deficiencies, new algorithms are being developed to exploit detailed parcel level street address data to predict locations of intercensal population growth. Early results are promising, pointing towards future population distribution refinements of the LandScan USA database.

The 2007 report of the Intergovernmental Panel on Climate Change (IPCC) suggests that weather and hydrologic extremes may be exacerbated by climate change. A better understanding of changes in the probability of storm and flood events and their interactions with built infrastructure systems and human social systems is needed in order to assess anticipatory risks scenarios and to evaluate mitigation and/or adaptation strategies. Progress on understanding the links between climate change and weather extremes has been limited, primarily due to the challenges involved with extracting extremes from massive volumes of disparate observations and simulations at multiple scales. The problems of uncertainty quantification and model validation become especially acute for extremes and obscure the relevance of future projections. New approaches in geographic data sciences are emerging to develop scalable algorithms which can handle nonlinear processes and extreme values. This modeling framework offers predictive insights that can be translated into tools for decision-making and policy analysis. An overview of this broad research area will be presented along with a particular emphasis on recent case studies. We will conclude by discussing ways in which this emerging research area may used to assess outstanding challenges to our national security, including potential impacts on critical infrastructure and the agility of our nation's quickly evolving bioenergy resources.

It is essential that the production and consumption of bioenergy is truly sustainable. However, current capabilities do not meet required energy goals and will likely have detrimental environmental and socioeconomic effects. Meeting these goals effectively and safely requires developing and implementing a sustainable bioenergy infrastructure. Oak Ridge National Laboratory is developing a multi-scale bioenergy infrastructure framework through a combination of a systems dynamic, geospatial information systems and geospatial optimization approaches. The geospatial optimization component analyzes a multi-objective tradeoff between factors such as which and how much feedstock/crops should be grown, where to locate the feedstocks, which forms of bioenergy should be produced (e.g. fuels, heat, power, biochemical co-products), and where to locate the bioenergy conversion facilities. The tradeoff of these decisions is measured in terms of direct costs (such as energy and transportation costs), as well as environmental impact (such as nutrient flux into rivers/streams), human health effects, and socio-economic impacts. These decisions are highly interdependent and strongly spatially linked, as well as influenced by climate change and spatial scale.Here I present the early-stage geospatial optimization work as applied to the 276 counties of the Tennessee Valley Authority, examining scenarios such as supplying 20% energy via bioenergy, minimizing sediment and nutrient flux, minimizing local habitat loss, and minimizing adverse socioeconomic impacts.

The LandScan USA population distribution model uses a multi-dimensional dasymetric modeling approach, which has allowed for the creation of highly detailed population data at a spatial resolution of 3 arc seconds (~90 m) but does not yet include business and leisure travelers. The objective of this study is to explore large variations in population distribution patterns caused by business and leisure travelers to special events. Special events including conventions, festivals, parades, and sporting events, can cause significant variation in the baseline population of an area due to the influx of business and leisure travelers. Special event data, hotel occupancy data, and the LandScan USA population distribution model are the three central input components to this analysis. Integrating the dynamic data (hotel occupancy/special event attendance) with very high resolution static data (LandScan USA) will improve the accuracy of population estimates thus enhancing the model's utility in assessing special scenarios such as natural disasters and human threats. Similar undertakings to assimilate dynamic data with LandScan USA population distribution data are continuously underway at Oak Ridge National Laboratory to improve and develop the model's functionality and effectiveness.

A recent example of unusual weather that may become more frequent with climate change occurred in early spring 2007 when a large Arctic air mass moved into the central and eastern United States following a very warm late winter. We documented effects of this freeze event on Walker Branch, a well-studied stream ecosystem in eastern Tennessee. The 2007 spring freeze killed newly emerged leaves in the forest canopy, dramatically increasing the amount of light reaching the stream. Measurements of photosynthetically active radiation (PAR), gross primary production (GPP), nitrate uptake, and growth of a dominant herbivore, the snail Elimia clavaeformis, were made during the spring and summer months after the freeze and compared with measurements made over the same months in years before the freeze. PAR at the stream surface was sustained at levels considerably above those normal for the late spring and summer months due to incomplete recovery of forest canopy leaf area following the freeze. Increased PAR caused a cascade of ecological effects in the stream. GPP was considerably higher (2-3 times) during the late spring and summer months when normally low light levels severely limit stream GPP. Higher rates of stream GPP in turn caused higher rates of nitrate uptake by the autotrophic community and lower nitrate concentrations in stream water. The higher rates of stream GPP also resulted in higher snail growth rates. Net nitrate uptake and snail growth rates are typically zero to negative during summer; however, in 2007 they were maintained at moderate levels. These results show how changes in forest vegetation phenology, a predicted consequence of global warming, can have dramatic effects on stream productivity at multiple trophic levels and on nutrient cycling due to tight coupling of forest and stream ecosystems. Future climate-induced changes in canopy structure and phenology may lead to significant effects on stream ecosystems. Our results also show the value of long-term research for the detection of climate change effects on ecosystems.

The report found that North America is currently a net source of carbon dioxide to the atmosphere, contributing to the global buildup of greenhouse gases in the atmosphere and associated changes in the earth's climate. North America's fossil-fuel emissions in 2003 (1856 million metric tons of carbon +-10% with 95% certainty) were 27% of global emissions. Approximately 85% of those emissions were from the United States, 9% from Canada and 6% from Mexico. The conversion of fossil fuels to energy (primarily electricity) is the single largest contributor, accounting for approximately 42% of North American fossil emissions in 2003. Transportation is the second largest, accounting for 31% of total emissions. Circa 2003, growing vegetation in North America removed approximately 500 million tons of carbon per year (+- 50%) from the atmosphere and stored it as plant material and soil organic matter. This land sink is equivalent to approximately 27% of the fossil-fuel emissions from North America. The imbalance between the fossil-fuel source and the sink on land (a source:sink ratio of nearly 4:1) is a net release to the atmosphere of 1350 million metric tons of carbon per year (+- 25%). Approximately 50% of North America's terrestrial sink is due to the regrowth of forests in the United States on former agricultural land that was last cultivated decades ago, and on timber land recovering from harvest. The second largest sink (approximately 25% of the North American sink) is associated with woody encroachment into grasslands and shrublands but is highly uncertain, known to no better than +- 100%, and may actually represent a small source. Other sinks are relatively small (individually 1-10% of the continental sink) and not well quantified with uncertainties of +- 100% or more. The future of the North American terrestrial sink is also highly uncertain. The contribution of forest regrowth is expected to decline as the maturing forests grow more slowly and take up less carbon dioxide from the atmosphere. But, this expectation is confounded by uncertainty in how regrowing forests and other sinks will respond to changes in climate and elevated atmospheric carbon dioxide concentrations.

An increase in the carbon stocks of the biosphere results in a decrease in atmospheric CO sub(2). However, changes in the terrestrial biosphere have climatic impacts beyond affecting the atmospheric concentration of CO sub(2). In particular, changes in the surface albedo can have a significant impact on the Earth's climate. Several recent studies suggest that the effect on mean Earth surface temperature due to changes in albedo, for instance from increasing biosphere carbon stocks, may be of comparable magnitude but opposite in sign to the temperature effect of removing the CO sub(2) from the atmosphere. This is particularly true if, for example, forests are established in areas where there is extensive snow cover and hence the albedo difference between forest and non-forest is large. We use simple examples to demonstrate the relative magnitudes of the carbon and albedo effects on mean Earth-surface temperature and how these can be expected to evolve with time. These illustrations suggest that, in terms of climate protection, we re-examine the relative merits of: 1) protecting existing forests vs planting forests where forests did not previously exist, and 2) managing forests to replace alternate fuels or energy-intensive products vs. managing forests to accumulate and store carbon.

Unlike many industrial air emission sources, R&D activities are highly variable and therefore do not have emission factors. Although R&D activities use many different materials, VOCs and HAPs are the primary air pollutants of concern. A methodology was developed that allowed ORNL to estimate potential VOC and HAP air emissions without monitoring or costly emission estimation techniques. The methodology developed is consistent with U.S. Environmental Protection Agency (EPA) language concerning R&D contained in Federal Register preamble language and other guidance documents. The study consisted of two distinct elements: (1) the estimation of potential HAP emissions from the entire facility, and (2) the estimation of potential VOC and HAP emissions from representative R&D activities, These estimates are needed for applicability determinations and to document that the majority of ORNL's R&D activities can be considered insignificant under the Tennessee Title V regulations. These emission estimates are based on an evaluation of several years of chemical procurement records and usage information supplied by laboratory personnel.

Sunfish (Lepomis auritus) living in a stream contaminated with 0.5-1 mu g/L dissolved inorganic mercury accumulated greater concentrations of total mercury at headwater sites, where the dissolved mercury concentrations were greatest, than they did at downstream sites. However, despite evidence from laboratory studies that dissolved inorganic mercury is rapidly accumulated by fish without transformation to methylmercury, methylmercury constituted 85% or more of the total mercury concentration in fish at all sites.

Wildlife populations have access to some radioactively contaminated sites at ORNL. Contaminated animals or animal nests within the Laboratory's boundaries have been found to contain super(90)Sr or super(137)Cs on the order of 10 super(-2)-10 super(4) Bq g super(-1) and trace amounts of other radionuclides (including transuranic elements). Animals that are capable of flight and animals with behavior patterns or developmental life stages involving contact with sediments in radioactive ponds, like benthic invertebrates, present the greatest potential for dispersal of radioactivity. The emigration of frogs and turtles from waste ponds also presents a potential for dispersal of radioactivity but over distances <5 km. Mud-dauber wasps (Hymenoptera) and swallows (Hirundinidae) may transport radioactive mud for nest building, but also over relatively short distances (0 times 2-1 km). Movement by small mammals is limited by several factors, including physical barriers and smaller home ranges. Larger animals, like white-tailed deer (Odocoileus virginianus), are potential vectors of radioactivity due to their greater body size, longer life expectancy, and larger home range. Larger animals contain greater amounts of total radioactivity than smaller animals, but tissue concentrations of super(137)Cs generally decline with body size.

Possible sources of contamination are reviewed briefly, and the maximum permissible concentrations of radioactive isotopes in water are listed. The concentration of radioactivity by natural agents, including physical, chemical, and biological factors, is considered. Experiments on the removal of radioactivity by conventional water-treatment processes showed that coagulation could remove more than 90 per cent of most cationic radionuclides with a valency of 3 or more, of phosphorus-32 as phosphate, of iodine-131 as iodide when silver nitrate was added, and of plutonium ; strontium and caesium were not removed. Filtration removed only those radioactive materials associated with suspended solids. Softening by the lime-soda ash process was effective for the removal of most of the radionuclides tested, including strontium, but did not remove caesium ; the removal of strontium was aided by addition of excess calcium. lon-exchange processes were very effective for removing both cationic and anionic radionuclides. Various modified treatment techniques were also studied. Strontium and other radionuclides which form insoluble phosphates could be removed by coagulation with phosphate ; in the removal of strontium it is important to control the pH value and the phosphate: calcium ratio. Soluble constituents could be removed by electrodialysis after removal of colloidal material. Metallic dusts, such as iron, removed more than 90 per cent of radioactive contaminants except iodine-131, caesium-137, and barium-137. High concentrations of clay materials were also effective, but involved disposal of large amounts of sludge. The most effective method for removing radioactivity was found to be distillation, although this method is expensive. Pilot-plant studies on the removal of mixed fission products showed that this is a function of the radionuclides present. Full-scale tests of military field units gave decontamination results which were as good as, or better than, those obtained in laboratory experiments or with stationary water-treatment units. Emergency water-treatment units, usually consisting of ion-exchange materials, were found to be more effective for treating small volumes of water, particularly water with little suspended matter. Various types of instruments for detecting and measuring radioactivity in water were compared, and are illustrated. Instruments have been developed for river and lake surveys, including monitoring of bottom sediments and determining activity in biological samples such as fish.

Rates of dissolution, volatilization, photolytic degradation, sorption and bioaccumulation of specific PAH were calculated in lotic and lentic environments. The model was used to forecast spatial and temporal concentrations of dissolved anthracene to within 15 per cent of concentrations measured in lotic microcosms. It overestimated periphyton accumulation of anthracene by 425 per cent, but was within 40-50 per cent of measured concentrations in stream sediments and clams. Mass-balance constraints and the number of parameters in FOAM suggest that values of model parameters might be correlated during the course of simulation.

The samples were tested for the presence of Legionella using the fluorescent antibody method and positive samples of air collected downwind from the plant and inside the equipment were also tested for infectivity by injection into guinea pigs. None of the air samples yielded infectious Legionella, but positive indications for Legionella in air samples taken during the shut-down period were significantly more probable than during normal operation. Most of the water and sludge samples reacted positively, the highest concentrations of Legionella occurring in sludge samples associated with cleaning of the condenser tubes. Highest concentrations in water samples were present in the cooling towers, and two of the three cooling tower water samples collected during the shut-down period proved infectious in guinea pigs.

At present, there are several land use/ land cover (LULC) datasets that can be used for feedstock estimation or are being used as inputs in predictive models. However, not all of them are suitable for the purpose they are being used. For example, the popular Global Trade Analysis Project (GTAP) model uses land use data that classifies agricultural land into cropland and pastureland; however, the fallow land which can switch between the two is unaccounted for. This can lead to errors when using this information for various projections and modeling. In this study, we compare some of the LULC datasets that are being used for feedstock estimation or as model inputs for similarities and dissimilarities including nomenclature of class names across different land covers and evaluate the ambiguity associated with them. We also discuss our data modeling efforts, which uses ancillary spatial databases to correct/enhance existing land cover data to produce an accurate national coverage of land cover information for agricultural land use.

Whereas it has been demonstrated that organic matter has high gas adsorption capacity, the mechanisms and the consequences of this adsorption in subsurface conditions are poorly understood. Small-angle scattering techniques can provide unique, pore-size-specific insight into the density of adsorbed CO2. This study reports the results of the first small-angle neutron scattering (SANS) and ultra-small angle neutron scattering (USANS) studies on coal, using the Seelyville Coal from the Illinois Basin as an example. Experimental conditions employed in this work were chosen to simulate a range of coal subsurface conditions including those at 518 feet depth (P,T) = (1-50 bar, 16ºC), and the coal was saturated with subcritical CO2. Experimental results illustrate that coal microstructure is unaffected by pressurised subcritical CO2, and these findings suggest that depths of burial do not constitute a stability barrier to storage of CO2. The physical density of CO2, fluid phase adsorbed in the porous coal matrix exceeds by a factor of 3-4 the density of the bulk fluid at the same thermodynamic conditions. The applied methodology can be extended to studies of the sorption kinetics and capability of other naturally occurring porous materials of interest for carbon geological storage (saline aquifers, porous rocks, basalts, etc.) as well as investigations of supercritical fluid mixtures (e.g. CO2 and methane) in various coals.

Additionally from a temporal perspective, census data represent primary residential locations and do not consider diurnal or transient population movements. These limitations may be mitigated by developing population data with a finer resolution in both space and time at sub-census block levels. Models for population estimation and distribution are developed by exploiting remotely sensed data as well as disparate spatial data. The fusion of disparate and often misaligned spatial data for models for developing a population database at the national to global scale is a challenging research issue. These models evolve with incremental developments of spatially refined population resulting from the availability of recent or higher resolution input data sets to the model parameters. Input data to the models include high resolution LIDAR data, detailed parcel level street address data, and a plethora of public and commercial spatial data sets that range from local to national in scope.

However, it is still unclear when and in what precise combination these sources and technologies will emerge as successful and sustainable solutions. Ideally, future plausible development and implementation strategies for alternative energy resources and technologies will secure and support a societal system in which energy, environment, and mobility interests are simultaneously optimized. Given the intertwined nature of such a system across wide geographic scales, assessing the effectiveness of possible planning strategies and discovering their unanticipated consequences require data collection, modeling, and simulation at the finest data, process, and societal response levels coupled with the system's behavior over large spatial and temporal scales. For knowledge discovery, characterization of the interaction between the human dynamics and transportation infrastructure is essential and requires integration of three distinct components, namely, data, models and computation. In this paper, we describe development and utilization of a high resolution demographic data driven approach for transportation modeling and simulation at Oak Ridge National Laboratory. The modeling and simulation results can be translated into precisely quantified impacts on energy use, the environment, economics, mobility, and other societal factors from local to regional and national scales JF - Papers from the Annual Meeting of the Association of American Geographers - 2009 AU - Bhaduri, Budhendra AU - Liu, Cheng AU - Nutaro, James J PB - Association of American Geographers, 1710 16th St, NW Washington, DC 20009 USA KW - Sustainability Science Abstracts KW - Data collection KW - Economics KW - Energy consumption KW - Environmental impact KW - Mobility KW - Oil KW - Simulation KW - Sustainable development KW - Technology KW - Transportation KW - demography KW - infrastructure KW - USA, Tennessee, Oak Ridge KW - M3 1010:Issues in Sustainable Development UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1093410526?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/Sustainability+Science+Abstracts&rft_val_fmt=info:ofi/fmt:kev:mtx:book&rft.genre=book&rft.jtitle=&rft.atitle=&rft.au=Bhaduri%2C+Budhendra%3BLiu%2C+Cheng%3BNutaro%2C+James+J&rft.aulast=Bhaduri&rft.aufirst=Budhendra&rft.date=&rft.volume=&rft.issue=&rft.spage=&rft.isbn=&rft.btitle=Developing+a+Knowledge+Discovery+Framework+for+Evaluating+Alternative+Transportation+Energy+Scenarios&rft.title=Developing+a+Knowledge+Discovery+Framework+for+Evaluating+Alternative+Transportation+Energy+Scenarios&rft.issn=&rft_id=info:doi/ LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2010-04-01 N1 - Last updated - 2012-10-08 ER -
