TY - JOUR T1 - Toxicity Test Using Life Stages of Champia parvula (Rhodophyta) AN - 19066772; 8910213 AB - A static-renewal, 11-day to 14-day toxicity test has been developed, using the life cycle of the marine red alga Champia parvula (C. Ag.) Harv., that measures the vegetative growth, formation of tetrasporangia (meiosis), and formation of cystocarps (sexual fusion). The procedure has been tested with silver, copper, cadmium, lead, and cyanide. The maximum acceptable toxicant concentration (MATC) ranges were calculated for vegetative growth of females and tetrasporophytes and for production of tetrasporangia based on statistically significant differences. The MATCs were determined for sexual reproduction using the presence or absence of cystocarps to measure significance which yielded MATC values similar to those determined by the other parameters. However, sexual reproduction was the most sensitive of the four end points examined because it dealt with absolute absence rather than statistical differences. The toxicity test with C. parvula is a relatively fast, simple, and inexpensive procedure for testing the effects of toxicants on growth and reproduction in macroalgae. All phases of the life cycle can be maintained in the laboratory (available year round) and can be exposed simultaneously. The results from tests with heavy metals and cyanide indicate that this procedure is comparable to the most sensitive marine animal chronic tests.

Six laboratories each conducted two 28-day flow-through tests, one with silver (as silver nitrate) as the toxicant and the other with the pesticide endosulfan. Muffled sand (from nonpolluted beaches) was used as sediment in the tests. The mean 28-day median lethal concentrations (LC50s) for the participating laboratories were 165 +or-52 micrograms/L for the tests with silver and 106 +or-24 for the test with endosulfan. The ratio of the highest to the lowest LC50 value was 2.23 for silver and 1.81 for endosulfan. The variability of the test for 28 days was about a factor of 2. There were no major problems with the test method or the biological aspects of the test. The details that caused some problems for participating laboratories were the chemical analysis of silver and the maintenance of the proper test concentrations, particularly of silver, in the experimental systems.

Significant portions of the DEHP losses from the water-column subsystem during the experiments were due to the complete breakdown of the parent compound to carbon dioxide (CO2). In the benthic subsystem, DEHP concentrations in the sediment were increased by more than 50 times the concentration in the water column during the winter and 250 times during the summer. Statistically significant reductions in the fluxes of ammonia (NH3) from the benthic subsystem were observed in microcosms receiving 100 micrograms of DEHP per liter during the summer. Concentrations of DEHP in selected bivalves ranged from 174 to 229,000 micrograms of DEHP per wet kilogram, depending upon the water column exposure concentrations and the season of the year. These results indicate that human exposure to DEHP could occur through ingestion of contaminated mollusks, crustaceans, and fish. Ecological effects were observed only in the sediment subsystem. An environmental assessment of DEHP based on a microcosm consisting of a water-column subsystem held at summer temperatures would have underestimated the potential hazards of this chemical. The only human exposure would have appeared to be indirect, perhaps through consumption of fish feeding on the water-column zooplankters, and the ecological effects would not have been observed.

A discussion of sampling gear recommended for use with the quadrat method is included. Treatment of plants for the purpose of identification and weight analysis is addressed, especially the problem of treating carbonate encrustations. Macrophytes are usually processed either while wet or after drying. Samples collected in the field can be identified, separated immediately, placed in plastic bags , and refrigerated or pressed and dried with a plant press for identificationand processing. Dry weight is determined by drying representative samples for 24hr or to a constant weight at 105 C. After samples have dried for a specified time period, they should cool for 1 hr in a desiccator before dry weights are determined. To ascertain the organic content (ash-free organic weight) of a sample or subsample, incinerate it in a muffle furnace of 550 C for 1 to 6 hr, depending on the amount of material to be ashed; cool the ashed sample in a desiccator; rewet it; and dry it for 24 hr at 105 C. Remove the ashed sample from the oven, place it in a desiccator, and allow it to cool for 1 hr; then weigh it to obtain ash content.

Water, fish, soil, sediments and air samples were analyzed. The highest levels ranged from 33,000 to 343,000 ppb, found in storage tanks and a contaminated horse arena. The highest levels in fish were found in suckers, ranging from 5 to 55 ng/kg. The highest levels found in fish were from specimens collected from the area where the highest sediment levels were observed. Although cleanup efforts are underway, investigations and monitoring of the problems are expected to continue for several years to come.

The facility manufactured hexachlorophene from tetrachlorobenzene with 2,4,5-trichlorophenol (TCP) produced as an intermediate. TCDD was formed as an unwanted trace contaminant of the TCP. A sampling survey of the Spring River, which drains the disposal sites, was conducted to determine if TCDD contamination had occurred. Levels detected in the upper reaches of the river tend to indicate that the contamination of the river has resulted from the waste management practices of the former company. Fish contamination above the point in the stream where pollution could enter the water could be explained by migration of the fishes. Two dams near Carthage, MO were expected to prevent sediment migration beyond that point and thus limit fish contamination to areas upstream of the dams. Contaminated fish were found for a distance of at least 21 miles beyond the dams, which were not physical barriers to fish movement in either direction. Bioconcentration of extremely low levels of TCDD from the aqueous phase may also explain the extent of the contamination. The detection limits were not sufficient to determine the sediment TCDD concentration in the river. TCDD was only found in sediments immediately downstream of the former manufacturing facility at 12 ng/kg.

AN - 14116591; 942538 AB - Adults of the bay scallop A. irradians were held in flowing seawater containing 5 or 10 mu g Cu/kg at ambient temperature and salinity. After eight weeks, scallops contained up to 91 and 310 mu g Cu/g dry weight, respectively, in the total soft parts. Copper uptake was linear over time. There was a significant inverse relation between dry weight and copper concentration ( mu g/g) in adductor muscle, visceral mass, and total soft tissue. A decrease in copper content occurred in the visceral mass and total soft parts during spawning in the control and 5 mu g Cu/kg treatments. There was no apparent decrease in copper concentration during spawning in any tissue of scallops from all three treatments. A. irradians is an excellent bio-indicator of copper, since accumulation was observed in the visceral mass at a seawater copper concentration of 1.8 mu g/kg.

Flow-through bioassays were used in this study of BBP with shiner perch (C. aggregata ). Using measured exposure concentrations, 96-hr LC sub(50)s averaged 0.51 mg/L. Effects on schooling behavior were found at 0.08 mg/L and coloration at 0.24 mg/L. Coupled with the behavioral changes, reduced brain levels of epinephrine found in surviving fish indicated that the mode of acute toxicity for BBP may be through its effects on the catecholamines of the central adrenergic nervous system.

AN - 14014239; 847790 AB - Using the transmission electron microscope, asbestos fibers have been assessed in kidney cortex of four groups of rats previously exposed to intermediate range feeding grade chrysotile asbestos. Newborn rats, from mothers gavaged with asbestos during pregnancy, were gavaged twice a week at the dose level of 50 mg/kg beginning at age day 7 until their natural death or sacrifice. Of the 20 rats comprising the four test groups, 17 were positive, average fibers recovery being 5.34 x 10 super(3)/mg dry weight. This study is consistent with the passage of chrysotile asbestos across the gastrointestinal wall.

AN - 13919663; 718009 AB - Widespread contamination of ground water by a variety of synthetic organic compounds has created a need for information about the biotransformation of these contaminants in aquifers and associated regions of the unsaturated subsurface. Selected organic pollutants were added aseptically to the samples at an initial concentration of 1 mg/liter water. No degradation of 1,1,1-trichloroethane, chloroform, or 1,1-dichloroethane was detected in any of the samples. Toluene and styrene was degraded slowly in samples from both positions at both sites. Chlorobenzene was degraded in samples from both positions at Pickett, but no degradation was detected in samples from Fort Polk. There was no detectable degradation of these three compounds in autoclaved samples. Tri- and tetrachloroethylene was degraded very slowly in some of the samples.

Survival of newly-hatched larvae and early juveniles was a sensitive measure. AC222,705 was about 20 times more toxic than permethrin. Predicted no-effect concentrations were between 0.66 and 1.4 ug per litre for permethrin and 0.03 and 0.07 ug per litre for AC222,705. The no-effect concentration for permethrin and snails was over 0.33 ug per litre. The residue concentrations for both pesticides increased with increased water concentration. Both permethrin and AC222,705 are toxic at low concentrations to early life stages of the fathead minnow.

All caused cell death although significant mortality was at levels greater than the EC50. Amdro did not kill S. costatum, Thalassiosira pseudonana, Isochrysis galblanc, Chlorella or Dunaliella tertiolecta, but was inhibitory to algae at low concentrations. Methodologically, lowest values for expression of toxicity should be considered as most closely approximating true toxicity, and these values should be calculated after only 2 days of exposure.

About 74 per cent of TQMS response factors for 53 pollutants were within plus or minus 15 per cent of values determined in the interlaboratory study. Their values were shown to be independent of the type of quadrupole scanned. The precision of the response factor determination was similar in the two cases (mean relative standard deviation 11.9 per cent).

Only PCB bioaccumulated above background concentrations, with fairly high levels being found in N. virens . Bioaccumulation was hindered by high organic content of sediment, although sediment concentration alone was not considered to reflect bioavailability. Exposure concentration resulting from sea disposal of contaminated sediments is related to the physical and chemical properties of the sediment and site-specific conditions.

Fish and sediment samples were collected from the headwaters to a distance of 96 miles downstream, during November and December 1981. Four laboratories were involved in the analysis of the samples, using different procedures for extraction with high resolution gas chromatography/low resolution mass spectrometry. TCDD was detected in fish from all the sampling locations, the highest concentration being 55 ng per kg. It was only found in sediments immediately downstream of the disused plant , at 12 ng per kg. Until further investigations have been carried out, the State authorities have imposed limits on the consumption of fish from the river.

The samples were analysed by electron capture gas chromatography and multiple ion detection gas chromatography-mass spectrometry, after Soxhlet extraction and Florisil chromatography. The chemicals most frequently found were p,p'-DDE , hexachlorobenzene and compounds of tech-chlordane . Many unidentified polychlorinated ion clusters were observed in the mass spectra of these samples in quantities insufficient to allow identification. Electron capture gas chromatography, even with high resolution capillary columns, is probably not sufficient alone to characterize environmental residues.

The discussion focuses on three particular process elements in the total environment, namely chemical change across the benthic boundary layer, the effect of sorption in direct photolysis, and volatilization. Sensitivity analyses were also performed to assess the magnitude of possible errors in the respective inputs. Satisfactory validation will depend on numerous tests of the performance of the model in predicting concentrations of chemicals in different environments, although comparison with the results obtained from the use of other models may give some guide to validity.

Maximal acceptable toxicant concentrations (MATC) ranges were determined for silver, copper, cadmium, lead and cyanide. The MATC values determined from the presence or absence of cystocarps were similar to those obtained from the other parameters. However, sexual reproduction was the most sensitive criteria. The results for cyanide were broadly in line with those obtained from other chronic bioassays using marine animals. JF - Aquatic Toxicology and Hazard Assessment: sixth symposium.

The selection of the test species and the nature of the dilution water might greatly influence the applicability of the results. Other factors, such as nutrition, acclimatization and generic selection, might also influence the accuracy of predictions based on laboratory data. The manner in which the laboratory test should be designed in order to provide meaningful results is discussed, depending on the objective of the test, ie to determine relative toxicities, to estimate safe levels, or to predict actual effects. Providing appropriate test parameters were chosen, it was considered that the response of laboratory organisms could provide a reasonable index of environmental behaviour and toxicity.

AN - 13622986; 513396 AB - Sensible heat flux data obtained from the U.S. Environmental Protection Agency's Regional Air Pollution Study in St. Louis, Missouri are presented and discussed. Large spatial variations exist in heat flux on both a land-use scale and the urban scale. Arguments based upon empirical data and sampling theory show that estimates of heat flux representative of an upwind fetch l sub(x) require a minimum observation height proportional to z super(3/4). The influence of advection on the magnitude of the heat flux is also explored for both the urban and sub-urban or land-use scales. The data clearly indicate that advection can strongly modulate and even dominate the vertical heat flux above surfaces in areas which maintain large horizontal temperature gradients. The advection contributions is positive for cold air advection and negative for warm air advection, and may result from either the urban heat island or land-use mesoscale features.

AN - 13594106; 492453 AB - A number of factors make the management of hazardous wastes complicated and expensive. The substances themselves are noxious and in some cases deadly, and that, combined with horrifying tales of past mismanagement of dump sites, has made it extremely difficult to overcome local opposition to the establishment of new disposal sites, which are urgently required in many countries. Many of the wastes are essentially non-degradable, and control of the sites must therefore be more-or-less permanent, which adds further to the costs. Contaminating wastes can reach the surrounding environment by a number of means--by surface run-off, by leaching into the groundwater, by direct contamination of soil--which makes the design and management of disposal sites more difficult and, again, more expensive. Finally the high cost of safe disposal tempts unscrupulous producers to cut corners, and unscrupulous disposal agents to opt for "midnight dumping." Consequently, monitoring the production of hazardous wastes and surveillance of its ultimate disposition have become significant additions to the total cost of disposal. The EPA has calculated that "administrative costs" account for about one-third of the total cost of hazardous waste disposal. JF - Ambio.

The possibility that there may be some disbenefits to the addition of these chemicals must be considered. It is essential to quantify any disbenefits and to minimize them while maximizing the beneficial side of the question. Three types of substances are examined: the disinfectants themselves (chlorine, ozone, chloramines, iodine or chlorine dioxide), the degradation products of those substances which are retained in water (chlorites, chlorates, hydrochlorites or iodates), and the chemical reaction products of those very potent chemically active substances with the other materials present in the water. Specific attention is directed toward the formation of trihalomethanes and their control. (Baker-IVI) JF - Environmental Health Perspectives Vol. 46, p 1-6, December, 1982. 1 Fig, 4 Tab.

A review of old as well as new literature shows that slow sand filters, rapid granular media filters, and DE filters are capable of removing bacteria, viruses, and cysts if designed and operated properly. Each of these filtration processes can be rendered ineffective by faulty design or by careless or improper operation. At slow sand filtration plants, controlling filtration rates and filtering to waste after filters are scraped are important aspects of filter operation. Effective coagulation and control of the filtered water 's turbidity at rapid rate filter plants will do much to assure that filtered water has a minimum number of microorganisms. The operator can control turbidity of the water more precisely by monitoring turbidity at each filter rather than at the clearwell. The particle size of diatomaceous earth (DE) selected for precoat and body feed influences removal of bacteria by DE filters. In order to remove viruses most efficiently by means of DE filtration, of some modification of either the filter aid or the raw water is needed. Raw water can be modified using cationic polymer. DE filtration is effective for removing cysts if an adequate precoat is used and the septum is kept very clean.

One channel was maintained at ambient seasonal Mississippi River water temperatures and the other at 10 C higher. Maximum water temperature reached 31.0 C in the ambient and 40.8 C in the heated channel. Elevated temperature seasonally altered macroinvertebrate abundance and life history in the channels. Few animals were found in the heated channel during the period of maximum water temperature. Most macroinvertebrate density and composition differences were confined to the channel riffles rather than the pools. Peak total density in the heated channel riffles occurred 3 or 4 weeks before the ambient channel. Total macroinvertebrate density was appreciably higher in the heated channel riffles during the winder and spring months and in the ambient channel riffles during the summer months. This seasonal alteration was due to composition differences of several identified taxa. Reproductive periods for one snail and one isopod species began about 2 and 3 months earlier respectively in the heated channel than in the ambient channel. No marked change occurred in the reproductive activities of an amphipod in the two channels. (Baker-FRC) JF - Water Research Vol 16, No 10, p 1465-1477, October, 1982. 8 fig, 3 Tab, 24 Ref.

Twenty-one chemicals of differing toxicity had been stored in the warehouse. Immediate damage to the groundwater and surface water was mitigated by the natural swales in the land and the hastily constructed retention dams, which contained the waste, and by the underlying layer of low-permeability blue clay. Contaminated water discharged through storm sewers to a nearby creek was temporarily contained by a bentonite-lined sand bag dam. This water was pumped into a quickly constructed 300,000 gal membrane-lined pit adjacent to the creek for storage and subsequent treatment with soda ash and activated carbon (1000 mg per liter dose). Because of the complex mixture of chemicals and difficulties with analysis, 72 hour static bioassays with fingerling perch were used to determine if the water had been sufficiently detoxified to return to the creek. Sludge produced from the flocculation process was disposed of in a landfill. Unburned products were placed in sealed drums and burned drums were placed in overpack drums for disposal in a hazardous waste landfill. The most heavily contaminated soil was removed to the landfill. The remainder of the debris-cleared site was treated with soda ash and powdered activated carbon to absorb toxic substances and encourage natural degradation processes.

Sampling was conducted on 6 cruises from April 1978 to August 1980. The highest percentage of positive stations (38% of stations positive for TC and 25% for FC) was located within 9 km of the disposal site center. The percentage of positive stations decreased with increasing distance from the center of the dumpsite. Positive samples were found as far as 37 km from the center. Sludge tended to travel in northeast and southwest directions and to settle in low spots. An area of at least 1190 sq km of ocean bottom was affected by the sludge dumping. The percentage of positive stations decreased with time. TC, FS, and amoebae were more persistent in sediments than FC. Therefore, FC can be considered an indicator of recent sludge deposition.

It uses mathematical programming to determine the levels of industrial pretreatment and municipal treatment which will meet the relevant environmental standards (sewer discharges, receiving water quality, and sludge quality) at minimum total cost. The problem is formulated as a nonlinear 0-1 integer program model. An implicit enumeration procedure that exploits the special structure of the problem is used for the solution. An analysis of heavy metals in the Kokomo, Indiana, treatment system showed that using uniform national standards for pretreatment was less cost-effective than using no minimum standards. Industrial sources accounted for 28% of total flow and 67-99% of Cd, Cr, Cu, Ni, and Zn entering the municipal plant. Cu was the critical receiving water parameter. If all Cu from the industrial sources were eliminated, other contributing sources would cause violation of the EPA limit 36% of the time using secondary municipal treatment and 22% of the time using tertiary municipal treatment. This method allows a city 's pretreatment requirements to be matched to local conditions. Using the desired receiving water quality as a goal, the treatment is distributed among the individual industries and the municipal plants on a cost-effective basis. In general, the industry with the largest pollutant input is required to treat to a higher level. The problem of differences in treatment levels may cause complaints of inequity, which must be resolved.

Pilot-scale diffused air aeration studies, pilot-scale granulated carbon and granulated synthetic resin columns, and boiling studies are described. When aeration was used to remove trichloroethylene, it and other solvents were removed. Adsorption was most effective when preceded by aeration. Boiling can remove solvents at point of use, but at least five minutes of vigorous boiling is needed. Preliminary cost estimates varied significantly with treatment process and contaminants. Estimates can only be made with thorough organic analysis and site-specific performance data. Data on the characteristics of the following compounds are given: trichloroethylene, tetrachchloroethylene, 1,1 ,1-trichloroethylene, cis-1,2-dichloroethylene, carbon tetrachloride, and 1,2-dichloroethane.

Excellent agreement was obtained between observed and calculated turbidities for 1977 (the year used to determine the coefficients) and 1976, 1978, and 1979. Results show that turbidity is directly related to wave action and the resulting bottom stress. Turbidity is not closely related to wind magnitude or wind direction. Sediments from the Maumee River significantly contribute to the amount of entrainable sediment near the intake. Sediment loadings, highest in spring, show a highly seasonal variation. High turbidity is produced by the transport of suspended solids from the Maumee River to the intake. There is a reasonable equality between turbidity in NTU units and suspended sediment concentrations in units of mg per liter.

' About 75 papers are noted which concern new isolation and enumeration procedures. Many of these are comparisons of different procedures such as membrane filter, most probable number and its variations, plating, and direct count using coliforms and other fecal bacteria. Selective procedures are given for microorganisms such as Legionella pneumophila, Yersinia, Campylobacter, Vibrio, Aeromonas, Klebsiella, Salmonella, and Listeria. There is great interest in commercially available diagnostic kits, multitest systems, and automated computerized methods for bacterial identification, as evidenced by about 25 publications on testing and comparison of these systems. Sampling considerations include special problems of collecting specimens from boats, under ice cover, in stratified waters, from aquifers, in streams, wastewaters, boiler water, industrial effluents, sediments, at bathing beaches, and in deep waters. New approaches to rapid methods for bacterial enumeration are discussed. Examples are radiometric, serological, electrochemical, enzyme, chromatographic, and chemiluminescent methods. Bacteria are used in bioassays for toxic or mutagenic substances, for example, Nitrobacter for assessing wastewater toxicity, effects of dyes on bacterial action, and improvements and development of the Ames Salmonella test. Quality control schemes are described, using control cultures and statistical methods. Several possible sources of error are mentioned, such as stacking plates, and nonuniform cooling rates. Health hazards to laboratory workers include infections from pathogens used in the Ames test and typhoid fever from the very infectious Salmonella typhi, sometimes used in testing disinfectants.

Analytical standards were extracted with dichloromethane and dried by passage through a glass wool/sodium sulfate column. After drying, the column was rinsed with hexane; the rinse was combined with the extracts, and the whole sample was reduced to about 0.5 milliliters under a stream of dry nitrogen before reconstitution to 5 milliliters by the addition of hexane. The extracts were refrigerated until LC/MS analysis, when they were reduced to 1.0 milliliters under a stream of liquid nitrogen. Average recoveries were 57% for aldicarb, 110% for aldicarb sulfone, and 101% for aldicarb sulfoxide. MS compares favorably with other detectors in terms of sensitivity, and the selectivity of the MS and minimum cleanup time required are added advantages.

Compared with 1973, the total flow reaching treatment plants has increased 36% to 95,594 million cu m per day, BOD removal has increased 13% to 76.4%, solids removal has increased 11% to 79.6%, and dry sludge has increased 58% to 23 ,763 metric tons per day. The population served by treatment plants in 1980 was 156.7 million (70% of the total population), 8.5% more than in 1976. Those served by secondary treatment or better increased 25.3% since 1976 to 119.4 million (53% of population). Since 1976 the number of secondary plants has increased by 58.8% to 6852 and the number of plants that do not discharge, by 36.1%; to 1361. During 1973 to 1979 $20 billion in federal, state, and local funds and $6.3 billion in non-government funds were spent for capital improvements. By 1985 it is expected that flows reaching treatment plants will reach 28,000 mgd, an increase of 14%, and BOD removal and suspended solids removal efficiencies will have increased to 82.6% and 83.4%, respectively.

Among the particles which must be removed by filtration are asbestos, bacteria, clay, protozoan cysts, fine rock particles, and viruses. In DE filtration small quantities of DE as a filter aid are continuously added to the feed. Filtration takes place on a permeable septum precoated with a thin layer of DE. Coagulants are rarely used. DE filtration may be done under pressure or vacuum. Removal of Giardia cysts can reach 99.99%; asbestos fibers, 99.99%; and plankton, 100%. Turbidities of 0.10 NTU are attainable. The granular media filtration process, most commonly used in the U.S., usually includes coagulation, flocculation, sedimentation, and filtration. If raw water quality is good, sedimentation and sometimes flocculation may be omitted. Continuous monitoring of turbidity can quickly detect early filter breakthrough. Filters should be backwashed before turbidity reaches the 1 NTU level. Giardia cysts and asbestos fibers removal is effective when turbidities do not exceed 0.1 NTU. Slow sand filtration, a biological process developed in the 19th century, effectively removes bacteria. The system is most suitable for small communities because capital costs are low and large areas of land are required for the filter beds.

The studies feature occurrence surveys, treatability studies to assess individual toxic removal mechanisms and pilot-scale plant removal studies using wastewater spiked with selected priority pollutants (metals and organics). In the plant removal studies, the treatment plant performance on spiked wastewater is usually compared to the performance of identical treatment on the unspiked raw wastewater. The assessments employ costly analyses (GC/MS and atomic adsorption methods) for the selected toxic substances in the various process streams and sludges of treatment plants. A biomonitoring approach to assess health and ecosystem effects is also being evaluated to supplement the specific toxic substance removal data. From the studies to date, conventional primary-activated sludge treatment is generally effective in removing toxic substances, typically achieving better than 90% removal of organics and from 60-80% removal of the metals. However, a number of the toxic substances were found in the plant final effluents at concentrations which, based upon EPA recommended water quality criteria may present a possible environmental hazard.

The study covers 158 facilities in SIC major group 3100 Leather and Leather products, and specifically subgroup SIC 3111, leather tanning and finishing. Effluent limitations guidelines are set forth for the degree of effluent reduction attainable through the application of the best practicable control technology currently available (BPT), and the best conventional technology pollutant control technology (BCT) which must be achieved by existing point sources by July 1, 1984. Standards of performance for new sources (NSPS) set forth the degree of effluent reduction that is achievable through the applications of the best available demonstrated control technology, processes, operating methods or other alternatives. Pretreatment standards for existing and new sources (PSES and PSNS) set forth the degree of effluent reduction that must be achieved in order to prevent the discharge of pollutants that pass through, interfere with, or are otherwise incompatible with the operations of POTWs. Supporting data, rationale, and methods for development of the effluent limitation guidelines and standards are contained in this document.

Information was collected to provide the Tacoma-Pierce County Health Department with chemical data needed to begin a preliminary assessment of any health risk possibly faced by persons eating fish and crabs from Commencement Bay and adjacent waters. Sampling was conducted from July 1981 to January 1982. Eighty-six non-salmonid fish and six Dungeness crabs were collected from popular sport fishing locations in the vicinity of Commencement Bay and from a remote reference area, Discovery Bay. Muscle tissue from these specimens was chemically analyzed for selected metals and organic compounds (EPA priority pollutants). Specimens from the Commencement Bay area generally had higher contaminant levels than did the specimens collected from Discovery Bay. The pollutant concentrations in the fish and crabs varied considerably, depending on the species and their location. The highest concentrations of polychlorinated biphenyls (PCB's) and pesticides were measured in fish from the Hylebos Waterway, while the highest total metal concentrations measured in fish were found in flatfish from the Point Defiance Dock. Regardless of where the crabs were collected, they contained total metal concentrations several times higher than the highest levels detected in fish. The mercury, PCB, and DDT concentrations measured were always well below the tolerance or action levels estabalished by U.S. Food and Drug Administration (FDA). However, few specific guidelines are available to assist in the direct assessment of the potential toxicity of many individual chemicals detected. The existing guidelines also do not address possible combinations of chemicals and metabolites. No attempt was made in this report to conduct an overall assessment based on these data.

Financing structures for water utilities are traditionally such that a reduction in demand may necessitate an increase in rates charged to the consumer, to avoid shortfalls in utility income for debt service and fixed operating expenses. In addition, a number of ' beneficiaries ' of the water supply system, such as those who enjoy fire protection, or those whose land is more attractive for development due to the availability of water, but who are not major consumptive users of water, tend not to bear the potential increased unit costs associated with user demand reduction. The problem can be considered as one of spatial economics - water system customers of certain classes, located in portions of the service area, subsidize other beneficiaries of the system in other classes and areas. The impact of demand reduction, coupled with the existing financial and revenue structure, can be expected to exacerbate the existing subsidizations of water system beneficiaries. The Drinking Water Research Division of USEPA has developed a systematic approach, organized as a set of computer programs, to assist analysts in examining problems of spatial economics and physical behavior of water distribution systems. The approach, known as the Water Supply Simulation Model (WSSM), consists of a data base describing the physical, economic, and spatial characteristics of the distribution system and program modules to: create and maintain the data base; display it graphically; perform hydraulic network, time of travel, and other physical analyses; and to perform economic allocations to develop spatial cost of service. The system is general-purpose in nature, and can easily be modified to suit the needs of a specific situation. Through combination of concepts of spatial analysis, spatial economics, data base management, and analytical mathematical modeling, the WSSM provides a powerful tool for examining the consequence of alternative policies related to water supply utilities. The structure of the WSSM, and sample applications, are described.

Secchi disc transparency, total depth, and field observations were recorded by 141 volunteers monitoring 87 lakes. Lakes ranged in transparency from 137.9 inches (Arbor in DuPage County) to 7.3 inches (Royal in Calhoun County). The clearest lakes were generally in the northwestern and southern part of the state; the most turbid, in the central and southcentral regions. Average transparencies of less than 4 ft (minimum recommended for bathing beaches) were reported in 63 of the 87 lakes. About 1/3 of the lakes had average values less than 2 ft, indicating use impairment problems. None of the monitored lakes were classified oligotrophic, 9 were mesotrophic, and the remainder were eutrophic. A primer of basic information on Illinois lakes for the layman is given. This includes origin, shape, hydrology, ecosystems, thermal stratification, succession and eutrophication, pollution, and water quality control measures.

The primary objectives of this project are to identify the most viable agricultural non-point source control strategy, demonstrate its effectiveness, develop a methodology to identify land causing water quality problems and to determine the appropriate RMS's. The physical, biological, and chemical characteristics of the Blue Creek watershed were studied since May, 1980. A comprehensive monitoring network for the entire Blue Creek Watershed was established by IEPA to document the basic hydrological, meterological, and water quality factors of the project area during 1980. The duration, timing and quantity of NPS pollutants were evaluated to determine land management effects on the water quality/quantity budget. Methods used for field and laboratory procedures are those accepted for agricultural related hydrology research. Analytical techniques are documented, but not detailed. By October 1, 1981, 70% of the soil loss reduction goal had been achieved, and erosion had been reduced by 16,495 tons/year. Precipitation was 17.5% above normal, with variability of streamflow attributed primarily to the precipitation patterns and land cover. High flows were measured from February through June while lower flows were measured during July and August. The rainfall-runoff ratio ranged from 4.7% to 80.1% during July and averaged 41.4% for Water Year 1981. Water samples were collected at seven stations in the Blue Creek Watershed during Phase II of the project, with three types of stations located within the watershed: watershed stations (A,B,C) sub-basin D and field stations (E,F,J).

The recent amendment of the municipal wastewater treatment construction grants program focuses efforts on achieving results through reduced federal involvement and increased state delegation. A problem of inefficiency of wastewater treatment plants in region II seems to result from a non-compliance factor. A diagnostic review of treatment plants in the region has been started, involving four phases: preliminary investigation, on-site inspection of every aspect of plant operations, identification of problems and drawing conclusions, and solution and implementation planning with both short and long term corrective actions. EPA has also begun a campaign of collecting overdue bills, which amount to millions of dollars nationally. Use of funds on actions which work directly toward improving water quality is stressed. Ocean dumping of sludge is being investigated. (Baker-FRC) JF - Clearwaters Vol 12, No 1, p 7, March, 1982. AU - Dewling, R T AD - Environmental Protection Agency New York.

Serious symptoms of acidification have been documented in lakes of New York 's Adirondack Mountains, far removed from any industrial activity. While precipitation is most acidic in the northeast US, the geographic extent of the problem encompasses the southeast and portions of the midwest and far west. A growing body of evidence suggests that acid precipitation adversely affects public welfare through loss of fish and other aquatic life, increased leaching of nutrient cations from the soil, possible reductions in crop and forest productivity, and the release of heavy metals or nutrients from rocks, soils and lake and stream bottom sediments. Research on aspects of acid rain is reviewed. The sensitivity of surface water bodies to acid precipitation was evaluated, and historical changes in surface waters were documented.

Several studies have shown that significant numbers of multiple drug-resistant coliforms occur in rivers, bays, bathing beaches, and coastal canals. This is a source of considerable concern, since bacteria carrying transmissible R-factors are capable of transferring antibiotic resistance to antibiotic-sensitive bacteria, raising the potential for transfer of antibiotic resistance to pathogenic species. The effect of ultraviolet (UV) light disinfection on antibiotic resistant coliforms in municipal wastewater effluents was investigated. Total coliforms and total coliforms resistant to streptomycin, tetracycline, or chloramphenicol were isolated from filtered activated sludge effluents before and after UV light irradiation. The wastewater effluent was effectively disinfected by the UV irradiation, but the percentage of the total surviving coliform population resistant to tetracycline or chloramphenicol was significantly higher than the percentage of the total coliform population resistant to those antibiotics prior to treatment. UV treatment did not affect the percentages of coliform resistant to streptomycin. Analysis of the multiple drug resistance patterns of 300 total coliform isolates revealed that 82% were resistant to two or more antibiotics. In addition, 46% of these isolates were capable of transferring antibiotic resistance to a sensitive strain of Escherichia coli.

Sources of contaminants may be natural (humic and fulvic acids), the treatment process (trihalomethanes), point sources (priority pollutants), and nonpoint sources (pesticides). In most cases it is necessary to quantify compounds at the ppb or ppt range. Basic steps in analysis are extraction, concentration, separation, detection and quantitation. Gas chromatography-mass spectrometry and gas chromatography with conventional detectors are useful for low to medium molecular weight compounds. Cost per sample is $100-1500 and $30-500, respectively. High performance liquid chromatography can be used to determine compositions of low to high molecular weight compounds at a cost of $50-500 per sample. Systems for measuring total organic carbon and total organic halogens are available for $9000-15,000 and $9000, respectively. The importance of a quality assurance program is emphasized. The bibliography lists many books, trade publications, and government documents which provide detailed information.

Damage from salt loading occurs mostly in the Lower Colorado River Basin. Remedies for salinity problems include collecting and treating or disposal of natural point sources. Cost-effective technologies for dealing with salt loadings due to irrigated agriculture include improved irrigation and on-farm management practices to reduce deep percoaltion loss and the building of canals and laterals to channel salt losses. Development of coal and oil shale resources in the Upper Colorado River Basin will necessitate use of river water, allowing even less downstream flow for salt dilution.

It is expected that slight changes will be made during the review process. In developing the upcoming metal finishing regulations, the EPA has responded to problem areas, and made modifications which will make these regulations clearer and more reasonable. The major changes include the use of concentration basis versus production; greater coverage of total plant process wastewater under one regulation; consideration of removal which occurs at the municipal wastewater treatment facility; and separation of studies of job shops and printed circuit board manufacturers to account for economic impact. Each of these major changes is discussed in detail, followed by a presentation of the staff recommendations for the regulation. Removal rates, and daily maximum and 30-day maximum effluent concentrations for appropriate metals are listed.

This paper presents an overview of guidelines applicable to reuse of municipal wastewaters as mandated by recent federal law, and the U.S. Environmental Protection Agency 's extension of this mandate into federal guidance for management of the EPA Construction Grants program. Historically, the earliest legislation did nothing to encourage wastewater reuse. The Federal Water Pollution Control Act of 1956 was, however, the turning point. It contained a modest construction grants program which included support for research and development of new technologies. Recent research and demonstration projects are rapidly advancing the knowledge 68 reuse of wastewaters in agriculture, silviculture and aquaculture. Finally, the EPA has issued a series of guidance documents to encourage proven and developing wastewater management technologies which include reuse.

In 1969, the Council on Environmental Quality (CEQ) was formed; and in 1970, the U.S. Environmental Protection Agency (EPA). Both began work on the PCB problem. CEQ was the catalyst in the formation of a federal interagency task force to coordinate the federal PCB effort. In May 1972 the task force issued a report concluding that PCB contamination was ubiquitous and represented an unquantified but undisputable hazard, and that the use of PCB should be restricted to essential applications that involve minimal direct human exposure. Once this report was issued, programs aimed at correcting the PCB problem were begun. In 1971 Monsanto, the sole domestic commercial producer of PCB, voluntarily restricted sales of PCB to ' closed-system uses, ' thereby limiting sales to manufacturers of transformers and capacitors. Monsanto also introduced what it felt was a less toxic PCB mixture, Aroclor 1016. The EPA recommended raising water quality standards to reduce PCB levels to less than 0.01 ppb. In February 1973 the Organization for European Community Development (OECD) issued a directive that recommended limiting the worldwide use of PCB. EPA designated PCB as toxic substances and set a national effluent standard pursuant to Section 307(a) of the Federal Water Pollution Control Act Amendments of 1972 (PL 92-500). In 1973 the Food and Drug Administration (FDA) published regulations limiting the use of PCB in food and feed facilities and establishing temporary tolerances for PCB levels in many food and feed items. In February 1977 EPA banned PCB discharges into waterways by capacitor and transformer manufacturers, and finally in 1976 the Toxic Substances Control Act (TSCA) (PL 94-469) was passed by Congress, requiring regulation of PCB.

The basic managerial framework of Section 311 of the Clean Water Act is carried over to the Superfund program. EPA 's Emergency Response team presently directs a national alerting system for rapid dissemination of information on personal safety and hazard assessment to protect public health and personnel in environmental emergency situations. This is made possible through the NIH/EPA OHM-TADS oil and Hazardous Materials Technical Assistance Data Systems computerized chemical information system. EPA is currently developing an integrated health and safety program for EPA employees involved in hazardous substance cleanup, which may serve as a model for the Interagency Working Group. The major components of this program include: development of generic safety plans for hazardous waste site investigations and spill response which can be tailored to particular incidents; a system of audits to ensure compliance with health and safety requirements; provisions for accident reporting; training requirements; general emergency procedures; criteria for medical surveillance of workers, including pre-assignment health assessments, periodic health assessments, maintenance of employee medical records for at least 30 yr; and rules concerning personnel practices such as wearing of protective clothing. The Superfund bill established a new agency within the Public Health Service, the agency for Toxic Substances and Disease Registry. The appropriate division of responsibilities and coordination among federal, state, and local government agencies with respect to health studies and registries must be resolved. The nature and scope of federal responsibilitiy for ensuring adequate health care for victims of chemical contamination, and for training of physicians and public health professionals capable of dealing with hazardous waste incidents at the non-federal level must also be defined.

No single model is uniquely suited for a specific problem and some problems require more than one model for their solution. Several planning and analysis models were applied to the flooding problem caused by poor urban drainage in the Four Mile Run watershed. The STORM model was used to develop flood frequency curves, while the WATERSHED model was used to simulate surface flow from individual subcatchments, pipes, and open channels. These simulations helped to ensure that future modifications in the watershed will not lead to future flooding problems. Planning and analysis models were used to reduce pollution load to the Sandusky River from combined sewer overflows in Bucyrus, Ohio (the Stormwater Management Model or SWMM) and to design and analyze urban drainage systems in Edmonton , Alberta (the HYMO model, STORM, and SWMM). The use of a planning and analysis model to extend a limited data set in a study done by the Illinois State Water Survey in Bloomington-Normal, Illinois is described. Here the QUAL-ILLUDAS model was used to assess the effects of storm runoff, point sources, and combined sewer overflows to establish the variability of constituent levels over time to aid in the planning of urban stormwater facilities. The EXTRAN (Extended Transport) block of the SWMM program was used to optimize the construction of relief sewers in the Borough of East York, Toronto. Three planning and analysis models, SEMSTORM, RUNOFF, and TRANSPORT, were used to assess the nonpoint source contribution to the pollution of Dorchester Bay from combined sewer overflows in Boston, Massachusetts. Other model applications open to the creative planner are considered. (See also W87-09096) (Geiger-PTT) JF - Urban Stormwater Hydrology, American Geophysical Union, Washington DC.

Microbial effects testing may provide a sensitive method for detecting potential environmental perturbations. The use of microbial effects tests might have alerted the Life Sciences Corporation to the problems that resulted from releasing what was probably Kepone, into the Hopewell, Virginia biological treatment plant. Microbial effects tests for measuring decomposition of organic substances have provided sensitive and rapid methods for detecting the effects of smelter emissions on microbial processes in soils. Some representative microbial effects tests provide measurements of growth, product formation, and substrate oxidation, reduction or disappearance. Microbial effects tests may provide sensitive, reproducible, and cost-effective methods for detecting the effects of toxic substances on microorganisms and their activities.

The chief priority in the water supply program is provision of safe drinking water by using highest quality water sources and protecting these sources from degradation. Most New England surface water sources are relatively free of pollution by municipal and industrial wastewater discharges.

AN - 15568318; 416543 AB - This report is based on regression analysis of one year of visibility and particle-monitoring data collected in the southwestern U.S. Average extinction coefficients for 23 sight paths were determined from contrast measurements made by teleradiometers at seven locations. Coarse and fine mass concentration data were collected with two-stage particle samplers at six locations. Overall, the coarse and fine particle data explain more than 75% of the variations in the particle extinction coefficient. Regression coefficients indicate measured coarse particles are one-half to one-third as efficient as fine particles in their contribution to extinction on a per unit mass basis. On the average, coarse particles contribute from 30% to as much as 80% of the particle-related optical extinction for this data set. JF - J. AIR POLLUT. CONTROL ASSOC.

AN - 15557260; 402346 AB - Two integrated sampling and analysis methods for determining NO sub(x) emissions in electric utility plants were developed and field tested. The collection systems consist of: a 4.0% potassium permanganate-2.0% sodium hydroxide solution in restricted-orifice impingers, and a 5 degree molecular sieve in midget impingers. Sample analysis is accomplished by a colorimetric or ion-chromatographic procedure with the alkaline-permanganate method and by a colorimetric procedure with the molecular sieve method. The alkaline-permanganate method gives excellent agreement with the EPA reference method, Method 7, for NO sub(x) measurements. The molecular sieve method shows a significant negative bias relative to Method 7. It is anticipated that the permanganate methods will be proposed as alternates to Method 7, for NO sub(x) determinations, under the EPA New Source Performance Standards. JF - J. AIR POLLUT.

AN - 15555553; 409915 AB - Three simplistic models are developed for evaluating the transport of organic pollutants through soil to ground water. The models consider mobility and first-order degradation. The first calculates linear sorption/desorption of the pollutant and first-order degradation without considering dispersion. The second is similar to the first but also considers dispersion. The third considers nonlinear sorption following a Freundlich equation and first-order degradation but does not consider dispersion. The models are compared to field data for the pesticides aldicarb and DDT. The models projected a lower mobility for DDT than was observed in the field.

AN - 15555270; 402562 AB - In recent years, considerable attention has focused on the concept of "human exposure" to environmental pollutants, but different investigators seem to have developed different definitions of this concept and used different approaches for estimating it. This paper reviews a number of "exposure" studies in a single environmental medium-air pollution-to see how others have defined this concept in the literature. Many previous investigators unfortunately calculate "exposures" by relying on data from fixed air monitoring stations, and they assume that people are located in the same place, usually their residential address, throughout a 24-h period.

Serial blood, urine, and fecal samples were taken from each animal for 3 weeks. A three-compartment, open system model with parallel first-order elimination into the urine and feces was developed to simulate mirex pharmacokinetics after either iv or po administration. All data were simulated on an analog-digital hybrid computer by simultaneous integration of the differential equations describing the model.

During the study opacities ranging from 2% to 57% were measured. The high opacities were usually obtained by reducing particulate control efficiencies. The data were compared with the acceptable standards of plus or minus 7.5% opacity deviation between observer and transmissometer used to certify observers of training plumes.

AN - 15552958; 402708 AB - This paper discusses the economics, advantages, potential aplications, and status and future research needs of porous pavements. Porous pavements are an available storm water management technique which can be used on parking lots and low volume roadways in order to reduce both storm water runoff volume and pollution. In addition, ground water recharge is enhanced. Also, cost reductions result due to elimination of curbs, drains, and small sized storm sewers. Porous asphalt pavements consist of a relatively thin course of open graded asphalt mix over a deep base of large size crushed stones. Water can be stored in the crushed stone base until it can percolate into the subbase or drain laterally. Other porous pavement types include concrete lattice blocks and a porous concrete mix.

AN - 15552748; 402635 AB - A new sampler has been developed which is a possible replacement for the flow controlled Hi-vol sampler. Field and laboratory tests have shown that the Bell-vol sampler offers advantages over the traditional Hi-vol for many applications. This sampler uses a passive pneumatic flow controller to regulate the flow rate rather than the blower speed control commonly used for AC/DC motors. This new control coupled with an AC inductive motor and a cyclone blower provides effective control of flow rates from 100 through 1500 L/min. Thus, the reliability of an inductive motor plus the absence of brushes are incorporated into the design. JF - J. AIR POLLUT. CONTROL ASSOC. AU - Bell, J P AD - Inorg. Pollut. Anal.

AN - 15548495; 412825 AB - Errors in pH measurement of 0.1-0.2 units can be propagate large errors in the predicted aqueous speciation. When accurate on-site analyses are impossible to obtain, changes in pH and alkalinity between the time of sampling and after transport to a laboratory must be minimized in many sampling programs. Several container and cap combinations were evaluated for their ability to preserve the pH and alkalinity of test waters that were out of equilibrium with atmospheric carbon dioxide over time periods representative of mail or other surface transport. Provided that no air bubbles were present when the sample bottle was filled and sealed, polyvinyl chloride bottles with caps having a conical polyethylene insert yielded the most satisfactory results. High density linear polyethylene bottles were also generally satisfactory. Cap design was observed to be very important. Guidelines for analysis and preservation are given, and if followed, laboratory measurements can be reliably substituted for field measurements in many instances.

AN - 15542967; 384784 AB - It has been previously demonstrated that carrier waves of 50 and 147 MHz, when sinusoidally amplitude modulated at 16 Hz (ELF), can cause enhanced efflux of radiolabeled calcium ion from chick brain tissue in vitro. This phenomenon occurs only when the samples are exposed to specific intensity ranges of the carrier wave. Unmodulated carrier waves do not affect the ion efflux. Since the ELF signal must be demodulated from the carrier wave to be effective, a study of the efflux enhancement due to the ELF signal may lead to an identification of the site of demodulation, as well as provide clues to the underlying mechanism. The authors report here that 16-Hz sinusoidal fields in the absence of a carrier wave can alter the efflux rate of calcium ions. The results show a frequency-dependent, field-induced enhancement of calcium-ion efflux within the ranges 5 to 7.5 V/m and 35 to 50 V/m (peak-to-peak incident field in air) with no enhancement within the ranges 1 to 2, 10 to 30, and 60 to 70 V/m.

AN - 15542281; 394985 AB - Concentrations of sulfur dioxide from model estimates and monitoring stations are available from previously conducted point source studies at seven power plant monitoring networks. Data for two to seven monitoring stations for either one or two years are available for examination of extreme values (specifically second highest, once-a-year) for 3 and 24 h averaging times. These data total 43 monitoring station-yeast. Stations whose elevations relative to the plant stack height result in the CRSTER model's marginal applicability, show overestimated concentrations by the same model. After removing those data which exceed a specific elevation criteria (6 of the 43 data sets), the comparison of second highest 3 and 24 h model estimates with measurements, although containing considerable scatter, reveals no significant bias toward over or under calculation. For 24 h period 68% are within a factor of two; for 3 h period 84% are within a factor of two. JF - Atmospheric Environment AU - Turner, D B AU - Irwin, J S AD - Meteorol. and Assess.

AN - 15541442; 418571 AB - Macroinvertebrates were sampled monthly from December 1976 to September 1977 in two 520 m long outdoor experimental channels. One channel was maintained at ambient seasonal Mississippi River water temperatures and the other 10 degree C higher. Maximum water temperature reached 31.0 degree C in the ambient and 40.8 degree C in th heated channel. Elevated temperature seasonally altered macroinvertebrate abundance and life history in the channels. Few animals were found in the heated channel during the period of maximum water temperature. Peak total density in the heated channel riffles occurred 3 or 4 weeks before the ambient channel. Total macroinvertebrate density was appreciably higher in the heated channel riffles during the winter and spring months and in the ambient channel riffles during the summer months. This seasonal alteration was due to composition differences of several identified taxa. JF - Water Research AU - Arthur, J W AU - Zischke, JA AU - Ericksen, G L AD - Monticello Ecol. Res.

AN - 15541347; 415929 AB - The thermal response of a human in the near-zone of an antenna was determined by numerical procedures. The approach taken was to modify the heat transfer equations for man in air to account for thermal loading due to the energy absorbed from the radiating antenna. The absorbed power density distribution in the human body was determined by considering the body and antenna to be a coupled system in which the resulting system of equations were solved by moment method procedures. This information was then analyzed by a thermal response model consisting of a series of transient conduction equations with internal heat generation due to metabolism, internal convective heat transfer due to blood flow, external interaction by convection and radiation, and cooling of the skin by sweating and evaporation. Internal heating patterns were calculated for two cases: a human in the near-zone of a quarter-wave monopoleand a half-wave dipole operating at 45 and 200 MHz, respectively. It was fund that negligible heating occurred for antennas with input power levels of less than 50 W. JF - IEEE Transactions on Microwave Theory and Techniques AU - Spiegel, R J AD - Bioeng.

AN - 15540109; 416456 AB - The body of information presented in this paper is directed towards engineers in the field of environmental sciences involved in measuring and/or evaluating the emissions from a variety of diesel engines or vehicles. This paper summarizes recent data obtained by EPA on identification and quantification of different emissions from a variety of diesel engines. Extensive work has been done comparing emissions from some light duty diesel and gasoline passenger cars. The work on the diesel vehicles was expanded to include tests with five different diesel fuels to determine how fuel composition affects emissions. This work showed that use of a poorer quality fuel frequently made emissions worse. The investigation of fuel composition continued with a project in which specific fuel parameters were systematically varied to determine their effect on emissions. EPA is presently testing a variety of fuels derived from coal and oil shale to determine their effects on emissions. JF - J. AIR POLLUT. CONTROL ASSOC.

AN - 15536444; 380881 AB - Adult rats anesthesized with pentobarbital and injected intravenously with a mixture of ( super(14)C)sucrose and ( super(3)H)inulin were exposed for 30 min to an environment at an ambient temperature of 22, 30, or 40 degree C, or were exposed at 22 degree C to 2450-MHz CW microwave radiation at power densities of 0, 10, 20, or 30 mW/cm super(2). A significant increase in permeation was found for sucrose but not for inulin. A correction factor was then derived from the warm-air experiments to correct for the increase in permeation of the brain associated with change in body temperature. This correction factor was applied to the data for the irradiated animals. After correcting the data for thermal effects of the microwave radiation, no significant increase in permeation was found.

AN - 15535559; 373004 AB - Past work on analyzing ground-source diffusion data in terms of surface-layer similarity theory is reviewed; these analyses assume that sigma sub(z)/L or h/L is a function of u*x square root uL. It is argued that an alternative scaling, h*/L versus x/L, is nearly as universal in that it is very weakly influenced by surface roughness, except for a modest influence in the free convective case, the advantage of this scaling is that it eliminates the need to reassess uu- as vertical diffusion progresses. The Prairie Grass data set is adjusted for the difference in source and sampling heights, and is plotted with this scaling.

AN - 15532331; 389119 AB - This study examined the fate of Prudhoe Bay crude oil in nearshore sediments of the Beaufort Sea, in situ, with emphasis on the role of microorganisms in the weathering process. The results indicate that oil is degraded in Arctic sediments very slowly; only after 1 year's exposure was biodegradation evident. Several factors probably contributed to the slow rate of microbial weathering. Abiotic weathering of the oil was also slow, with limited loss of low molecular weight aliphatic and aromatic hydrocarbons during 2 years' exposure. Significant features of the overall weathering process were: lack of initial loss of low molecular weight compounds; aliphatic compounds were not preferentially degraded over aromatic compounds and C sub(17) and lower molecular weight normal alkanes were preferentially degraded over higher molecular weight alkanes. The results of this study indicate that hydrocarbons will persist relatively unaltered for several years if Beaufort Sea sediments are contaminated with petroleum. JF - Marine environmental research.

AN - 15529077; 374870 AB - The EPA Office of Air Quality Planning and Standards (OAQPS) is developing a new Aerometric Information Reporting System (AIRS) to consolidate and improve the support now provided by a number of existing software systems, including the National Emissions Data System (NEDS), Storage and Retrieval of Aerometric Data (SAROAD), Hazardous and Trace Emissions System (HATREMS), and Comprehensive Data Handling System (CDHS). AIRS is being designed to provide an interactive, user-oriented data base management system which facilitates the collection, validation, storage, retrieval, and analysis of emissions and air quality data. This paper presents anticipated engineering design concepts for the source emissions portion of the AIRS data base. Data base structure and data element definition, new data editing and screening capabilities, and proposed reporting and data analysis capabilities are identified. The principal benefits to system users in terms of improved procedures for input, retrieval, and analysis of data are highlighted. JF - J. AIR POLLUT. CONTROL ASSOC.

AN - 15527160; 356317 AB - Viruses of animals, plants, and bacteria abound in sewage and receiving waters. Their ecological impact has, for the most part, gone unheeded except as it relates to viruses from human sources. Viruses present at levels infective to man have been recovered from waters used for recreational or drinking purposes. Their presence in a water environment virtually always denotes prior contamination by domestic wastes. Neither conventional sewage treatment processes nor the discharge to land or water of sludges produced by these processes achieve full viral control. Many environmental virologists advocate the setting of permissible virus limits for those recreational and potable waters dominated by wasterwater effluents. The initiation of regulatory pressure to restrict virus discharges into these water environments has been instituted in Montgomery County, Maryland, and in the states of California and Arizona.

AN - 15526425; 356058 AB - Regulatory agencies deal with risks that cannot be controlled by the marketplace. Pesticide regulation involves a balancing of risks and benefits. The precision of risk assessment must be consistent with other inputs. Options are finite: continue use, restrict use, ban use. Decisions must withstand legal tests and strike a balance between timeliness and certainty. Regulatory decisions approach moral decisions. The assessment of chlorobenzilate demonstrates the multidimensional process. Because of uncertainties and data gaps, public policy choices must be factored into the assessment. The process can be improved by being more systematic and by dealing more explicitly with uncertainties. JF - AM. STAT.

The authors of the study theorized that CFC's released in the lower atmosphere would not be destroyed by any natural process, but would slowly migrate to the stratosphere. There they would be broken down by ultraviolet radiation, releasing chlorine atoms that would in turn react with, and destroy, ozone molecules. JF - AM. STAT.

AN - 15526321; 355607 AB - Tri-o-cresyl phosphate (TOCP) and O-ethyl O-(4-cyanophenyl) phenylphosphonothioate (cyanofenphos, Surecide) were found to be delayed neurotoxicants. They were administered to chickens by gavage at 100 and 30 mg/kg multiplied by d for 15 d, respectively. In CD-1 mice neither TOCP nor cyanophenphos induced any of the usually recognized clinical symptoms of neuropathy when administered daily by gavage at 262 or 31.25 mg/kg multiplied by d for 30 d, respectively. In the chickens, TOCP and cyanofenphos produced about 98 and 90% in vivo inhibition of brain neurotoxic esterase (NTE) activity. In the mice, 24 h after the last daily dose, TOCP and cyanofenphos produced only about 50 and 40% in vivo inhibition of the brain NTE activity. Parathion (O,O-diethyl O-(4-nitrophenyl) phosphorothioate), at 2 or 6.75 mg/kg multiplied by d for 15 or 30 d, did not induce neuropathy in either chicken or mice and produced no significant in vivo inhibition of brain NTE activity at the end of the dosing regimen. The specific activity of NTE in control chicken brain crude homogenate was much higher than that in mouse brain homogenate.

AN - 15524881; 355642 AB - Whole-body evaporative heat loss was measured as whole-body evaporative water loss in mice during a 90-min exposure to 2450-MHz microwave radiation at an ambient temperature of 20 degree C and in non-exposed mice maintained at ambient temperatures of 20, 25, 30, 33, and 35 degree C. A specific absorption rate of microwave radiation in excess of 29 W/Kg was required to produce an increase in heat loss. For absorption rates ranging from 29 to 44 W/Kg, the mouse dissipated 65% of the total absorbed heat by water evaporation; the remainder was dissipated passively. The data collected in the mouse may be extrapolated to larger species, such as man, but only by an exponential relationship. Using this relationship, it was shown that a threshold specific absorption rate of 29 W/Kg in a 0.033-Kg mouse was equivalent to approximately 0.25 W/Kg in a 70-Kg human. JF - J. MICROWAVE POWER.

AN - 15524319; 356448 AB - Benomyl, a systemic fungicide whose molecular basis of action is inhibition of tubulin polymerization, was administered during organogenesis via the dietary and gavage routes to pregnant Wistar rats, and via the gavage route to pregnant CD-1 mice. Benomyl was fetotoxic and teratogenic in both species via the po route of administration, producing a broad spectrum of malformations at a dose of 62.5 mg/kg/day in the rat and 100 mg/kg/day in the mouse. Via the dietary route of administration, benomyl produced fetotoxicity, but no teratogenic effects. The fetotoxic potential of benomyl from dietary exposure was approximately an order of magnitude less effective than from gavage exposure. Benomyl did not affect postnatal growth, viability, or locomotor activity at subteratogenic doses. The most sensitive indicator of perinatal exposure to benomyl via the po route of administration was a permanent reduction in testes and accessory sex gland weight noted in male offspring of dams receiving 31.2 mg/kg/day benomyl during gestation and lactation. No effects on any parameters were evident in rats receiving 15.6 mg/kg/day by po gavage. The relevance of the two routes of administration for risk extrapolation is discussed.

AN - 15524285; 356436 AB - Groups of male CBA/J mice were injected with Salmonella typhimurium lipopolysaccharide (LPS) and irradiaated with 2450 MHz (CW) microwaves. The 50% lethal dose (LD sub(50)) of LPS was determined for mice irradiated at 30, 20, 10 and 5 mW/cm super(2) immediately folowing injection. The average specific absorption rate was approximately 0.6 W/kg per 1 mW/cm super(2) incident power. An equal number of animals served as sham-irradiated controls for each power density. The mice were placed individually in small containers and were maintained at 22 degree C and 50% relative humidity during a 2 hour irradiation period. Following irradiation the mice were returned to their home cages and were observed for 48 hr. A significant decrease in the LPS dose required to kill 50% of the mice was observed at power densities of 20 and 30 mW/cm super(2). High ambient temperature (37 degree C) also potentiated the lethal effect of endotoxin. Microwave irradiation prior to LPS injection, however, did not affect the lethal action of LPS.

The average specific absorption rate (SAR) was 16.5 W/Kg. Two experiments were performed under these conditions. At 3 and 6 weeks of age the mice were assessed for development of the primary immune response to sheep erythrocytes, in vitro mitogen-stimulated lymphocyte proliferation, and natural killer (NK) cell activity. No consistent significance in the primary immune response, in the mitogen response, or in the NK cell activity was observed between irradiated and sham-irradiated mice. JF - J. MICROWAVE POWER.

AN - 15523641; 355338 AB - There is considerable need to harmonize not only the internationally-recognized test methods but also the fundamental processes and conditions by which test data are developed. As more countries pass legislation to control chemical substances, governmental authorities will receive substantial quantities of test data from national and international laboratories for assessment of the potential hazard that these chemicals may pose to human health and the environment. In order to confidently rely upon these test data, laboratory testing should be conducted under procedures and conditions which will ensure the quality and integrity of the test data. If individual countries can rely upon internationally-developed test data, duplicative testing can be avoided, thereby reducing the burdens of cost and time imposed upon international chemical trade. Reciprocal acceptance of test data internationally could contribute substantially to international trade and avoid possible trade barriers. JF - IN "QUAL. ASSURANCE OF TOXICOLOG. DATA".

AN - 15523013; 355408 AB - This overview represents much of the discussion and summarizes many of the concerns emerging from the recent APCA Specialty Conference, "In-Situ Air Quality Monitoring from Moving Platforms." Users of mobile air quality monitoring systems have been hampered in their attempts to generate dependable data because of a lack of suitable instrumentation. Most equipment used in mobile systems was designed for laboratory or stationary monitoring applications and cannot cope well with the harsh environment encountered in aircraft or other mobile platforms. Only through innovative modifications have investigators been able to utilize off-the-shelf equipment. The technology exists, however, for manufacturers to build a much higher quality product if only a market incentive could be created. This paper outlines problem areas which need to be addressed in the production of reliable "mobile quality" instrumentation, and suggests some market incentives. JF - J. AIR POLLUT. CONTROL ASSOC.

A tracer, sulfur hexafluoride, was released from the forest and collected downwind in order to define the dispersive characteristics of the atmosphere. Simultaneously, alpha -pinene concentrations were measured both upwind and downwind of the forest. A Gaussian plume dispersion algorithm incorporating hydrocarbon lose due to O sub(3) and OH reaction was used to estimate alpha -pinene emissions.

AN - 15521990; 355472 AB - The relationship between chlorophyll A, total phosphorus, secchi disk depth, and trophic state were examined using data on U.S. lakes collected by U.S. EPA's, national Eutrophication Survey. By comparing predicted secchi disk depths with observed summer secchi disk depths in 757 lakes, it was determined that in many lakes nonchlorophyll related light attenuation is important in controlling the amount of chlorophyll A produced per unit of total phosphorus. Rankings of 44 lakes by 18 different trophic state measurements and single and multivariable indices were compared with rankings provided by mean summer ambient total phosphorus and chlorophyll A. The trophic state measurements and indices were much more successful in ranking the lakes against total phosphorus than chlorophyll A, indicating that there are differences in the relative trophic rankings of many of the lakes depending upon whether primary nutrients or biological manifestations are used as the ranking mechanism.

AN - 15518075; 358963 AB - In a recent article in Transportation Research, Daganoz (1981) described a model of gap acceptance that permits the mean of the gap acceptance function to vary among drivers and permits the duration of the shortest acceptable gap for each driver to vary among gaps. The model contains several constant parameters whose values must be estimated statistically from observations of drivers' behavior. The results of numerical experiments reported by Daganzo (1981) suggested that the values of the parameters cannot be estimated by the method of maximum likelihood, which is the most obvious estimation technique, and Daganzo proposed using a sequential estimation method instead. The sequential method appeared to yield reasonable numerical results. In this paper, it is shown that subject to certain reasonable assumptions concerning the true parameter values and the probability distribution of gap durations, the maximum likelihood method does, in fact, yield consistent estimates of the parameters of Daganzo's model, whereas the sequential method does not. Hence, maximum likelihood is the better estimation method for this model. JF - TRANSPORT. RES.

AN - 15512142; 326925 AB - Fresh water lake sediment removal is usually undertaken to deepen a lake and increase its volume to enhance fish production, to remove nutrient rich sediment, to remove toxic or hazardous material, or to reduce the abundance of rooted aquatic plants. Review of more than 60 projects and five case histories reveals that the first three objectives are usually met through sediment removal. The technique is recommened for deeping and for long range reduction of phosphorus release from sediment. Sediment removal to control toxic materials is possible with minimal environmental impact when proper equipment is used, but it may more than double the cost.

AN - 15511107; 333845 AB - A wide variety of hardware suitable for data acquisition is available. The desktop computer based DAS described above was chosen after consideration of cost, system flexibility, reliability, availability of repair service, and management familiarity with a range of hardware. The system was designed in 1979 and because of the rapid evolution of desktop computers, an identical system might not be chosen today; nevertheless, the system performed according to the requirements and ran for several years without requiring replacement. Operating the system was straightforward; no difficulty was reported in training operators to handle the system. The uninterruptable power supplies worked without failure throughout many power line outages. In these applications the most significant advantages of the system have been its flexibility and the ease with which one can make changes in the software to accommodate changes in a given study or to tailor the system to a new study.

This paper summarizes recent data obtained by EPA on identification and quantification of different emissions (i.e. characterization) from a variety of diesel engines. The effects of turbocharging, advanced injection timing, indirect vs. direct injection, exhaust gas recirculation (EGR), and different fuel pumps on HC, CO, NO sub(x), sulfates, aldehyde, and particulate emissions were determined by testing several heavy duty diesel engines. A heavy duty gasoline engine was tested for comparison. Limited testing was done on a diesel bus engine under malfunction conditions (conditions different from manufacturer's recommended specifications). JF - J. AIR POLLUT. CONTROL ASSOC.

The essential characteristics, advantages, and problems associated with personal monitors are discussed and compared to the characteristics of fixed-station monitoring. Personal monitors generally aresuperior to fixed monitors for estimating personal exposure , at least for selected air pollutants. They make it possible to collect data on pollutant concentrations that people normally come into contact with throughout their daily activities -- indoors, outdoors, and in various modes of transportation. These new instruments ultimately could transform the way in which human exposure to air pollution is estimated. JF - J. AIR POLLUT. CONTROL ASSOC. AU - Wallace, LA AU - Ott, W R AD - Off.

AN - 15464912; 271079 AB - The reactivities of five partially-oxygeneated organic compounds were measured. In terms of ozone-forming ability, the most reactive of the organics studied was methyl methacrylate. Vinyl acetate and 2-ethoxy ethanol were found to be moderately reactive. Ethylene oxide and o-isopropyl phenol exhibited low reactivity. Smog chamber contaminaton and its effects on measured reactivity were also studied. It was found that contaminaton can significantly affect the reactivity of slowly-reacting organics. The use of smog chambers, therefore, to obtain reactivity data for low-reactive organics is not recommended.

AN - 15464187; 271074 AB - Groups of 15 rats each were exposed 20 hr/day, 7 days/week for 28 days to a 1:14 dilution of either raw or irradiated exhaust using a six-cylinder Nissan diesel engine. Body weight gains were significantly reduced during exposure to diesel exhaust with a greater decrease during exposure to irradiated compared with raw exhaust. Arterial blood gases and standard bicarbonate remained unchanged. Arterial blood pH was slightly but significantly decreased in the animals previously exposed to irradiated exhaust. Residual volume (RV) and wet lung weight were unchanged after exposure to either condition, while vital capacity (VC) and total lung capacity (TLC) were increased (P < 0.05) following exposure to raw exhaust. The shape of the deflation PV curves were nearly identical among the three groups. It was concluded that 28 days exposure to a 1:14 dilution of diesel exhaust emissions resulted in only minor functional changes in the lungs.

The plotted concentrations are the daily maximum 1-h average and the daily inflow, that representative of air flowing into the metropolitan region during a 4-h midday period. In general, the inflow varies from 30 ppb in the winter to 70 ppb in the summer, but under strong high pressure systems may approach or exceed 120 ppb. Evidence of local ozone production is apparent, with the highest recorded maximum in the two years being 255 ppb.

The agreement covers some two dozen issues related to RCRA, as well as a number of questions involving aspects of the agency's consolidated permit program and the National Pollutant Discharge Elimination System (NPDES). Under the settlement, a company could begin constructing a new hazardous waste management facility as soon as 180 days after it filed Parts A and B of the permit application, assuming the company already had necessary construction approvals from other government agencies. However, such a facility could not begin operating until the company actually received its RCRA permit. JF - SOLID WASTES MGMT.

The suggested design represents a compilation of ideas from states that are currently developing ground-water programs. The outline should provide advice to those states that have not yet begun to develop a program, but recognize the need to do so. Given the limited funds available to develop and implement a ground-water management program, the states should use the design as a guide, and devote their efforts to defining a state ground water protection policy, identifying and evaluating existing and potential contamination sources, and to developing and implementing procedures to prevent or mitigate the contamination problems.

AN - 15416105; 234061 AB - A number of relationships can be obtained from the measurements made of fine-mode and coarse-mode particle mass and particle sulfur concentrations at ten sites in and around St. Louis in 1975 through 1977. Fine-mode and coarse-mode particle mass occur at about equal concentration levels, but with significant variations with quarter of the year and between urban and rural sites. These variations are associated with those of fine-mode sulfur which as ammonium sulfate is the single largest contributor to fine-mode mass. Ammonium sulfate can constitute up to seven-tenths of the fine-mode mass at non-urban sites during the 3rd quarter of the year. The gradient of the several components of the mass between urban and rural sites vary from just over 1:1 for fine-mode sulfur to over 2:1 for coarse-mode sulfur. The gradients for fine-mode and coarse-mode mass between urban and rural sites ranged near 1.5-1. JF - Atmospheric Environment AU - Altshuller, A P AD - Environ. Sci. Res. Lab., EPA, Res.

AN - 15388817; 213329 AB - Duplicate, 8-compartment, continuous-flow microcosms were used to study the effects of acid addition on community function, algal community structure, and degradation of a plasticizer, diethyl phthalate. Inputs of HCl decreased the alkalinity (measured as CaCO sub(3)) from 25 to 8 mg 1 super(-1), creating diurnal H super(+) activity curves that indicated that the ecosystem was being severely stressed. Removal of excess acid was accompanied by a return to a normal diurnal pH cycle. Nutrient concentrations and O sub(2) production did not give a definite indication of stress resulting from the addition of acid. Algal community structure and total biomass were not affected by acid inputs. Also, degradation rates of diethyl phtalate by the aquatic bacteria were similar for the control and the acid-stressed systems. These studies indicate that acid inputs can significantly disrupt normal ecosystem function, such as diurnal pH cycling, without having a measurable impact on other parameters usually monitored in aquatic ecosystems.

AN - 15381615; 212360 AB - An environmental assessment of the transformation and transport pathways of hexachlorocyclopentadiene (hex)in simulated aquatic ecosystems is presented. Hydrolytic and photolytic disappearance rate constants in distilled and natural waters and in sediments-water systems are given. Sediments in defined sediment-water systems do not significantly affect the disappearance rate constants, compared to distilled water values, for the hydrolytic and photoytic processes. Water solubility, octanol/water partition coefficient, and vapor pressure for hex are also reported and compared with literature values. Fate and transport asessment using an evaluative model indicates that hex will not likely reach substantial steady-state concentrations in the various compartments of the simulated ecosystems. The results also indicate that photolysis and, to a lesser extent, hydrolysis are the predominant degradation processes; export via the water column is the predominant transport process.

AN - 15379632; 206537 AB - This paper describes a modeling technique for estimating responses of urban travelers to gasoline shortages under three different procedures for allocating scarce gasoline supplies. The allocation procedures are: allow the price of gasoline to rise to a market clearing level, allocate gasoline by means of white-market coupons, and allocate gasoline by means of traditional rationing. The modeling technique is based on a system of disaggregate travel demand models and provides for representation of non-price restraints on gasoline consumption (e.g. traditional rationing) and for changes in multi-destination travel, as well as for changes in gasoline prices and in modes, destinations for frequencies of travel. The application of the modeling technique is illustrated by using it to estimate the effects of a gasoline shortage in the Washington, D.C., area. The results of this application indicate that in all allocation procedures tested, reductions in non-work trip frequencies and lengths are the main sources of gasoline savings in the presence of shortages. Transit improvements and carpool i ncentives moderate but do not prevent the effects of shortages on non-work travel. JF - TRANSPORT. RES.

AN - 15356249; 181426 AB - Chrome tannery sludge applied to agricultural land may have benefits in terms of added N for crop growth. An experiment was designed to compare tannery waste with commercial N fertilizer and investigate the potential of the waste as an alternative or supplement to commercial fertilizer. Soils with 38% and 7% organic C and N content of 1.3% and 0.2%, respectively, were amended with lime, commercial N fertilizer, or tannery sludge containing 1.6% Cr. A portion of the tannery waste was supplemented with additional Cr super(3+) salt before adding to the soils. The amended soils were analyzed for total Cr, ammonium acetate extractable Cr, selected nutrient and trace element concentrations. The tannery sludge increased soil pH, total Cr and N, S, Ca, P, Mg, and Na concentrations. DTPA extractable Cr increased only when Cr super(3+) salt was added, but soil pH decreased markedly. Electroconductivity of the soils increased with the waste application rate and, at the highest rate of Cr super(3+) salt addition, far exceeded values recommended for successful crop production. The acidic, high salt conditions complicated interpretation of the Cr super(3+) salt addition results. JF - WATER, AIR, AND SOIL POLLUT.

AN - 14229257; 1042129 AB - The existing channel depth in the Hampton Roads is 45 feet. This depth severely limits the ability of larger coal colliers, greater than 80,000 DWT, to load. The U.S. Army Corps of Engineers (COE) extensively studied the feasibility of deepening the channel to 55 feet and found it economically justifiable. In 1980 the COE prepared a Draft Environmental Impact Statement which proposed expansion of the channel to 55 feet but which presented a number of environmental concerns. These concerns centered on the impact of filling 6,000 acres of the Dismal Swamp, potential contamination of ground water supplies from spoil disposal, and changes in salinity in the tributaries to the Hampton Roads as a result of channel deepening.

Details are given for schemes for managed natural systems in the U.S.A. including land application of wastewater or sludge. Tables show treatment efficiencies of wastewater by slow rate land treatment, rapid infiltration, overland flow, wetlands and water hyacinths and the land required, costs, labour, parts and supplies and total energy. Examples of these processes are given. Previous bad management of waste disposal sites leads to real and imagined problems in introducing natural processes now. Possible difficulties include groundwater contamination, disease transmission, odours and political, economic and legal constraints. Climatic conditions can also cause short term problems but the author calls for natural processes to be given full consideration.

However, the applicability of the method required that difficulties in defining the ventilatory characteristics of fish be alleviated. Using the bluegill, Lepomis macrochirus, and lake Superior water (pH 7.5, total hardness, 44-46 mg per litre), three types of coughing manoeuvres could be established: (1) the most common, large amplitude cough owing to interruption and momentary reversal of developing bioelectric potential of a ventilating cycle followed by a substantial burst in potential; (2) a quick spike-like cough, occurring as a momentary pause in potential, followed by a burst; (3) interruption and reversal near the peak of ventilating cycle, and without accompanying burst in potential.

A project to study new sewer designs based on maintaining adequate low flow solids carrying velocity to alleviate sewer sedimentation is described, from which it is shown that there are feasible ways of controlling first-flush pollution from storm loads, largely by increasing conduit slopes and providing cunette sections. There is some discussion on various types of sewer rehabilitation techniques and other ways of controlling infiltration to sewer systems by upstream storage/attenuation. The last part of the article describes combined sewer overflow regulators.

Arsenic levels were high in many of the organisms studied but the element is believed to be present in a relatively non-toxic organic form.

The variables being studied include rainfall, climates, types of receiving waters and the hydrology and geomorphology of the receiving waters. Particular criticisms of NURP : not relating to worthwhile improvements; not considering whether particular forms of a contaminant are actually harmful; using water quality criteria which are not relevant to short exposure urban runoff, and not making bioassays a significant element of the programme, are answered by the authors.

The system was evaluated under varying regimes of temperature and hardness, with minimum zinc concentrations producing a change in fish ventilation rate during 96-hour test periods compared with chronic exposure tests of embryos and early juveniles; the results show that the system is at least as sensitive as more conventional long-term toxicity tests for screening potentially harmful chemicals.

In addition, the water solubility and half-life of the pesticides in lake Superior were determined. The toxicity of controlled release pesticides appears to be similar to that of the technical grade. Slight differences are attributed to degradation and parent compound ratios on the affinity of the polyethylene capsules for the pesticide. Environmental dangers appear to be their potential for chronic effects on aquatic life due to their persistence.

The acquisition system collected the data automatically by monitoring 20 infrared light-emitting diode/phototransistor pairs. The three exposure conditions were a steep chemical gradient in which the metal concentration was increased over time; a steep gradient in which a fish was exposed to a single concentration; and a shallow chemical gradient. With each regime a choice was available for the fish between control and toxicant water. The results indicate that the steep gradient, in which a single fish is exposed to several consecutively increasing doses, is the simplest method and provides data amenable to statistical analysis. The computer-based system is rapid, relatively inexpensive and accurate.

They report the results of laboratory and pilot-plant studies which have been carried out to ascertain the effects of aeration, adsorption and boiling on water containing the solvents. Groundwater rather than surface waters are likely to contain significant concentrations of the compounds and the establishment of acceptable limits is unlikely to be resolved in U.S.A. in the near future. Results of experiments on adsorption preceded by aeration indicate that this system is likely to be an effective treatment. Boiling vigorously for at least five minutes in a well-ventilated area can remove the solvent at point of use. Preliminary estimates of costs vary widely. They were made on the basis of theoretical concepts and available empirical data and emphasize the need for thorough organic analysis and site-specific performance data.

The study has three components: collection of baseline cost data for utilities withdrawing or planning to withdraw water from the Potomac, analysis of various augmentation possibilities under differing demand conditions, and evaluation of different supply strategies as to their cost impact on individual utilities. The study confirmed that Washington's water supply problems are due to political interaction as much as to shortages in water availability and the findings should be invaluable for future evaluation of supply schemes.

Their objectives are to reclaim and reuse wastewater and its constituents, the recovery and conservation of energy and reduction of costs compared with conventional technologies. It is considered that managed natural biological systems which treat and recycle municipal wastewater appear to be suitable for the I/A program. These may involve variations of traditional land treatment concepts (using agricultural lands, forests, ponds or wetlands) or intensive aquaculture systems such as fish farming, nutrient films and hydroponic cultures. The current status and future possibilities of natural treatment systems are discussed and research has shown that overland low flow projects may be efficient and cost-effective for achieving secondary treatment and ammonia removal. Water hyacinth systems are considered to be ready for fairly routine use. The possible environmental problems associated with these systems are described, but it is considered that a multidisciplinary approach should be able to overcome them, as well as the disadvantages of land requirement and lack of operational control.

The 96 hour EC50 (shell deposition) for Eastern oysters, Crassostrea virginica was 0.71 mg per litre. It should, however, be noted that solubility of creosote was incomplete at the higher concentrations used. In the deactivation experiments, glass carboys of creosote in seawater were exposed to outdoor ambient sunlight and temperature. Chemical analysis by gas chromatography gave an estimated half-life for marine-grade creosote of less than 1 week. In bioassays with mysids, creosote toxicity was reduced by 50 per cent between days 3 and 5.

Kinetic models of the disappearance of phosphorus in soils are proposed on the assumption that a fast initial sorption mechanism is followed by a slow secondary precipitation mechanism leading to formulation of relatively insoluble phosphorus compounds. Mathematical models of phosphorus transport processes in soils are then considered, and the results of model predictions shown to be in reasonable agreement with breakthrough curves determined by experiment. Further studies of the effect of ambient variables are called for, while undue reliance on sorption isotherms is claimed to underestimate the phosphorus capacity of soils in practice.

Mercury as MMC was more toxic than as HgCl2 as determined by effects on survival and production of young. Tissue mercury levels tolerated without mortality were 9 times greater when added as MMC rather than HgCl2 . Accumulation was rapid but 35 and 57 per cent of the mercury added as MMC and HgCl2 respectively was lost within 4 days of transfer to control water. The effect of MMC on survival and reproduction was 3 and 28 times greater respectively in flow-through conditions compared to renewed static. In the case of HgCl2 , this difference was less than 2 fold. In static conditions, only 20-30 per cent of the total toxicant was found to remain in the water phase after 7 days.

The potential hazard is essentially a function of the potential to harm the environment, and the level of exposure. The first of these factors can be assessed on the basis of bioassays, while the second can be determined from laboratory measurements of the behaviour of the chemical when subjected to a variety of external forces. Typical determinands of environmental behaviour are the resistance to biodegradation, the effects of sunlight, sorption behaviour and the solubility and volatility characteristics of the substance in question. Other relevant information may be based on structure /activity relationships, a field in which there has been only limited progress to date. Ideally, a thorough study of the physical and chemical properties of a product should enable a theoretical model to be established capable of simulating its fate in the environment.

Standardization of the test procedure is stressed and some published data for freshwater and marine organisms are examined, showing that for certain materials some species of aquatic animals are 5000 times more sensitive than others, whereas for different materials the sensitivity range is less than 50-fold. The criterion of death adopted in assessing the LC50 value is also discussed and the concept of functional death is advanced as a means of taking into account other extreme consequences such as immobilization or loss of equilibrium, which would reduce the chances of survival in the wild to zero.

Sixty eight chemicals for which 96 h median lethal concentration values were available from EPA tests were also tested using the Microtox toxicity analyser based on the luminescent response of Photobacterium phosphoreum cells. A 50 per cent reduction in light output is the criterion for the EC50 of each toxicant. Good correlations existed between the two sets of data in respect of chemicals of similar structure particularly within semihomologous series, but only order of magnitude predictions of fish toxicity data could be obtained from the results f luminescence measurements, which could however be useful for screening purposes.

Survival of newly hatched larvae was the most sensitive indicator of the effect of both pesticides on fathead minnows, Pydrin being approximately 90 times more toxic than Kelthane. The lowest observed effect concentrations for these insecticides were 13 times less than the 96 h LC50 value established using standard fish bioassays with fathead minnows. For Kelthane bioconcentration factors of 3700 for fathead minnows and 10,000 for amphipods were recorded, and the mean concentration factor for Pydrin in minnows was 3200. Residual levels and concentration factors for both pesticides increased with increasing test concentrations in the water. JF - Aquatic Toxicology and Hazard Assessment (edited by J. G. Pearson. R. B.

The results of the system are reported with respect to the effects of copper and cadmium on the responses of Stage 2 and 3 nauplii of the barnacle Balanus improvisus. Both metals altered non-directed (spontaneous) swimming activity in a dose-related biphasic manner. Hyperactivity in response to low-level concentrations was followed by suppressed activity in the presence of higher metal concentrations. Copper also altered phototaxis in these nauplii; at higher concentrations (72 and 138 ug per litre) a shift to negative phototaxis was observed in some individuals. The sensitivity of these behavioural responses is compared with that of two developmental parameters monitored in the course of the same assay.

The purpose of the program was to focus scientific research to meet management objectives. A preliminary summary of the scientific findings indicates the following major problems: The upper Bay, mid Bay, and eastern shore tributaries are either highly or moderately nutrient enriched compared to historic levels. Sediments in the upper Bay and middle Bay have elevated levels of metals. Nonpoint sources are a significant source of nutrients, particularly nitrogen. Point sources are the major source of phosphorus for the severely enriched areas. The major reivers such as the James, Potomac, and Susquehanna are important contributors of nutrients, metals, and synthetic organic compounds. JF - Atlantica.

The conditions governing the effectiveness of each of these processes are discussed, both as regards the specific pollutant and the medium in which it is present. Recognizing that compounds with similar chemical and physical properties are likely to undergo removal to roughly the same extent, organic priority pollutants previously detected in treated sewage were classified into six different groups according to their reported concentrations, namely 1.0, 5.0, 10.0, 25, 50 and 100 ug per litre. The data relating to selected compounds in the 10, 50 and over 100 ug per litre clusters are presented and discussed from the standpoint of chemical and structural similarities, and their effect on treatment performance.

AN - 13838555; 696228 AB - This paper discusses the potential effects of drilling fluids on semienclosed bodies of water, such as estuaries. Fluids used in the extraction of oil and gas in offshore and coastal waters are comprised chiefly of a mixture of barite, water and chemical additives and are pumped into the well through the drill pipe and the drill bit. Drilling fluids have been discharged into outer continental shelf waters for many years, but there is some concern of potential ecological impact when they are discharged near coral reefs or in bays and estuaries. The concern is based on potential adverse effects of the fluids on corals, shellfish, finfish, grass and general productivity.

They were monitored in air samples using a personal air quality monitor and in breath using a spirometer. Tap water levels were compared to those in human breath. Total trihalomethanes (THM) exceeded the interim drinking water standard of 100 ng per ml in all samples from both areas. Chloroform and tetrachloroethylene levels were higher in the non-industrial area. Bromodichloromethane levels were similar in both areas. Small amounts of chlorobenzene occurred but no benzene, carbon tetrachloride, 1,2-dichloroethane, vinylidene chloride or 1,1,1trichlorethane were detected. Of the total daily intake of VOC through air and water, drinking water was an important contributor of only two of the compounds measured, chloroform (79 per cent) and bromodichloromethane (76 per cent).

Screening models are illustrated by describing a methodology applicable to large areas of land and another applied to a large number of chemicals. The application of models in a planning context is illustrated by a local planning agency's use in developing nonpoint source control strategies and by the federal government's use in assessing potential exposure to a pesticide. Development of design criteria is illustrated by summarizing the long history of model use to develop effluent limits in the Holston River basin (Tennessee).

A "block-shaped" model vehicle was fixed in position over the test-section floor while the floor moved at the freestream air speed to produce a uniform, shear-free, approach flow. This simulates an automobile traveling along a straight highway under calm atmospheric conditions. Vertical and lateral profiles of mean and fluctuating velocities and Reynolds stresses in the wake of the vehicle were obtained using a hot-film anemometer with an X-probe. Profiles were taken at distances of 10-80 model heights downwind. A momentum type wake was observed behind the block-shaped vehicle. The wake doses not have a simple self-preserving form. However, it is possible to collapse the velocity deficit with one length and one velocity scale. JF - Atmospheric Environment AU - Eskridge, R E AU - Thompson, R S AD - Meteorol. and Assess.

AN - 13622054; 513395 AB - Once a risk has been identified, risk estimation requires the determination of dose-response functions that can be applied to expected doses. That is, toxicity and exposure analyses are the critical elements in risk assessment. There are four major methods to examine toxicity: (1) epidemiological evidence of actual human response; (2) animal (in vivo) experiments; (3) short-term in vitro tests; and (4) structure-activity analysis. Where data are available, the Environmental Protection Agency (EPA) uses one or a combination of the first two approaches. While short-term tests and structure-activity analysis are accepted as useful screening devices to help set priorities for further testing, there is no accepted procedure for their use in predicting human response to specific chemicals or exposure levels.

AN - 13619285; 513402 AB - In a wind tunnel study, the influence of the highly turbulent region found in the lee of a model building upon plumes emitted from short stacks was examined through smoke visualization and tracer gas concentration mappings. A thick, simulated atmospheric boundary layer was used to provide background dispersion. A rectangular-shaped building with its length equal to twice its height and width was oriented with the long side perpendicular to the approaching wind. The stack was placed midway along the lee side of the building. In all phases of the study, each smoke or tracer release from the stack was repeated with the building removed. This allowed for a simple demonstration of the buidling wake effects. A simple mathematical model was developed that provided good estimates of concentrations in the building wake. The building influence was found to be reduced with increases in the effective source height. JF - Atmospheric Environment AU - Huber, AH AU - Snyder, W H AD - Meteorol. and Assess. Div., Environ.

AN - 13607847; 486823 AB - In studies designed to test whether disinfection practive contributes significantly to the tumor initiating activity found in drinking water mixed results have been obtained. In one experiment, water disinfected by chlorination, ozonation or combined chlorine resulted in a significantly greater number of papillomas when compared to nondisinfected water. In two subsequent experiments, where water was obtained from the Ohio River at different times of the year, no evidence of increased initiating activity was observed with any disinfectant. Analysis of water obtained at the comparable times of the year for total organic halogen, and trihalomethane formation revealed a substantial variation in the formation of these products. Comparisons of the specific mutagenic activity of the chlorinated products suggests that the commercial material might provide a useful model for studying health hazards associated with disinfection reactions by-products.

AN - 13606733; 486743 AB - Concern over the presence of trihalomethanes and other chlorinated by-products in chlorine-disinfected drinking water has led to extensive investigations of treatment options for controlling these by-products. Among these treatment options is the use of an alternative disinfectant such as chlorine dioxide. Although chlorine dioxide does not react to produce trihalomethanes, considerable evidence does exist that chlorine dioxide, like chlorine, will produce other organic by-products. The literature describes chlorinated and nonchlorinated derivatives including acids, epoxides, quinones, aldehydes, disulfides, and sulfonic acids that are products of reactions carried out under conditions that are vastly different from those experienced during drinking water treatment. Evidence is beginning to emerge, however, that some by-products in these categories may be produced. JF - Environmental Health Perspectives AU - Stevens, A A AD - US EPA, Munic. Environ. Res.

AN - 13606080; 486914 AB - Chloroform is a drinking water contaminant that has been demonstrated to be carcinogenic to mice and rats resulting in an increased incidence of liver and kidney tumors, respectively. The mechanism of chloroform carcinogenicity might be by tumor initiation and/or promotion. Since induction of ornithine decarboxylase (ODC) activity has been proposed as a molecular marker for tumor promoters, the authors have investigated the effect of chloroform on ODC activity in rats. Chloroform induced a dose-dependent increase of hepatic ODC with an apparent threshold at 100 daily dosing of chloroform for 7 days the liver became less susceptible, with the last dose of chloroform resulting in only 10% of the activity observed after a single dose. Nuclear RNA polymerase I activity was also induced by chloroform.

AN - 13543273; 441172 AB - During the Regional Air Pollution Study (RAPS), winds in the St. Louis region were recorded by surface stations (hourly averages) and by multiple upper air releases (on-the-hour). This study analyzes differences (1) between upper air and surface resultant winds, (2) among upper air winds at 4 sites, and (3) among surface winds at 25 sites. The extensive data set provides a statistical basis for indicating the representativeness of individual observations, and the results show considerable variation between simultaneously-measured winds determined by alternate means. Based on Gaussian plume dispersion, the spatial variations in wind direction are translated into expected departures between predictions and observations of pollutant concentrations. Inaccurate specification of winds in air quality simulation models is likely to be a substantial contributor to differences between short-term predictions and observations on an urban scale.

(1) The traditional agressiveness index based on calcite saturation is inadequate to describe the degradation of asbestos cement pipe. The presence of naturally-occurring protective materials, pH, carbonates, calcium, disinfectant concentrations, temperature, and organic matter must also be considered. (2) Some materials cause pipe matrix dissolution but do not necessarily release asbestos fibers. (3) The chloride, sulfate, and orthophosphate salts of zinc are satifactory corrosion inhibitors for asbestos cement pipe at the proper concentrations and pH. The mechanism involves formation of a zinc hydroxy carbonate precipitate which reacts with the pipe surface to form a harder zinc silicate coating. (4) Tthe Zn orthophosphate protects against corrosion in a metal-asbestos cement pipe system through the action of the orthophosphate rather than Zn. Zinc chloride and sulfate are not effective in these situations. (5) A degraded asbestos cement pipe with loose fibers cannot be readily rehabilitated by Zn treatment. (6) Results of Zn solubility modeling presented in this paper are also applicable to studies of new galvanized piping.

Corrosivity may result from low pH, low buffering capacity, presence of dissolved oxygen, high total dissolved solids, high halogen and sulfate/alkalinity ratio, and high temperature. The major health effects of corrosive water are lead toxicity, increased incidence of hypertension and cardiovascular disease produced by cadmium, and the possibility of cancer from ingestion of asbestos fibers. Possible benefits of reducing corrosivity are less health risk, fewer operations and maintenance problems, and improved esthetics (reduction of discolored water and stained fixtures). Negative effects of increasing the water hardness to reduce corrosivity are negligible. Evidence indicates that water treatment to reduce corrosivity is warranted, especially for larger systems. Costs per life saved vary from $1720 (145 lives saved per year) in a 100 mgd plant serving 1 million people to $114,000 (0.0036 lives saved per year) in a 2500 gpd plant serving 2500 people. Annual per capita costs for lime treatment of soft water range from 25 cents for the 100 mgd plant to $16.40 for the 2500 gpd plant. This study illustrates the uncertainties involved in placing an economic value on benefits from reduction in incidence of diseases.

Although the precursors and processess are widely used, it is only the particular critical combinations that produce priority pollutants. Most of these are associated with the early stages of production and are generally refined away on the route to the commercial product. Of the 116 recognized organic priority pollutants, 75 were verified in this study. Although some feed stocks such as acrylonitrile, phenol, and vinyl chloride are themselves priority pollutants, some are also introduced as impurities or reaction products of impurities in feedstocks or solvents. A table lists the 17 plastics and synthetic fibers effluents which contained greater than 0.5 ppm of priority pollutants, the monomers, and the chemical nature of pollutants generated. A similar table lists 71 organic chemical effluents which contained greater than 0.5 ppm priority pollutants, with the generic processes, feedstocks, and chemical nature of pollutants generated.

If the ratio is greater than 1, the source is classified as dirty, and if less than 1, as clean. When severities downstream from the source are of interest, a transport model must be used to relate the concentrations to factors measured at the source. Use of a multiplicative model on an effluent discharge from an industry is illustrated. The model is designed to classify a large number of the clean-dirty borderline cases as dirty, while minimizing the number of rather clean sources which are classified incorrectly. Another illustration using a textile plant effluent measured total suspended solids over 40 days to produce 57 observations. Considering only one measurement, 47 of the 57 cases were designated as dirty, but taking two observations on each of five representative days produced a clean classification. Severity at a downstream point can be calculated using concentration of pollutant in effluent, effluent discharge rate, river flow rate, and the standard concentration.

AN - 733443469; 16345869 AB - Using batch cultures, we determined transformation rates for low concentrations of two toxicants-an insecticide, methyl parathion (O,O-dimethyl O-p-nitrophenyl phosphorothioate), and a plasticizer, diethyl phthalate-by aufwuchs, aquatic microbial growth attached to submerged surfaces or suspended in streamers or mats. Aufwuchs samples were collected from field sites, an indoor channel, and a continuous-flow fermentor. Aufwuchs fungi, protozoa, and algae did not transform methyl parathion or diethyl phthalate, but bacteria rapidly transformed both chemicals. Second-order transformation rate coefficients, K(b), based on total plate counts of bacteria in aufwuchs, were determined for potential use in a mathematical model capable of predicting the transport and fate of chemicals in aquatic systems. K(b) for both methyl parathion and diethyl phthalate decreased as the concentration of total bacteria, [B], increased in aufwuchs. This effect resulted from the proportion of nontransformer to transformer bacteria increasing as [B] increased and from the rate of transformation per transformer cell decreasing as [B] increased. First-order transformation rate coefficients, K(1), were relatively stable per unit of surface area colonized by aufwuchs, because K(b) decreased as [B] increased (K(1) = K(b) x [B]).

Water containing 1.0 or 0.2 mg per liter of the organic compound was applied at the rate of 14 cm per day for 45 days. Concentrations of compounds in the effluents and the amounts volatilized were determined and the mass balances calculated. Chemicals which percolated rapidly through the soil without degradation were chloroform, 1 ,2-dibromo-3-chloropropane, dichlorobromomethane, 1 ,2-dichloroethane, tetrachloroethene, 1,1,2-trichloroethane, and trichloroethene; retardation factors (velocity of tritiated water through the soil divided by the apparent velocity of pollutant through soil) were 2.5 or less. Little or no biodegradation was observed. From 19 to 65% of chemical applied to the surface reached the 140 cm depth, and the rest volatilized. Retardation of chlorinated benzenes generally increased with decreasing water solubility. Some degradation occurred in this group of compounds. Bis(2-chloroethyl) ether did not degrade, and its retardation factor was < 1.5. A method was developed to predict the retardation factors on the basis of water solubility of the chemical and soil organic C content. Soils containing low organic matter are more pollution-vulnerable. (Cassar-FRC) JF - Journal of Environmental Quality Vol 10, No 4, p 501-506, October/December, 1981. 3 Fig, 4 Tab, 34 Ref.

In 1977, under the Section 208 Program, 353 lakes were assessed. In 1979, a more quantitative assessment of 64 lakes was undertaken. Sample parameters and preservation/analysis methodologies are provided. The 1980 Ambient Lake Monitoring Program establishes baselines and defines trends in lake water quality, and identifies new or existing problem areas. The pilot Volunteer Lake Monitoring Program will allow citizens to learn about lakes/lake management and also provide baseline information that would not otherwise be gathered, due to limited resources. The Clean Lakes Program determines lake water quality problems, examines alternatives for improving water quality, and implements these alternatives. The USEPA has specific regulations for administering the Program and has established three types of assistance: lake survey and classification, Phase 1 diagnostic/feasibility study, and Phase 2 implementation awards. Awards are for publicly-owned freshwater lakes and are only made to state agencies. Phase 1 awards are up to $100,000 and require a 30% non-federal cost share. Phase 2 awards require a 50% non-federal share. These awards are not contingent upon one another. The Illinois EPA applies for the funds and administers the program. In July 1980, the Illinois EPA received a one-time federal grant of $100,000 (70% federal, 30% state) to develop the state 's lake classification and priority ranking. It also received awards for three Phase 1 diagnostic/feasibility study projects in July 1980 totaling $104,650. The program needs public support to succeed.

The water quality, use impairment, and characteristics of these lakes are influenced by origin, location, morphology, hydrology, watershed characteristics, and meteorological conditions. This report discusses six artificial impoundments in Central Illinois that were part of the Illinois Environmental Protection Agency 's (IEPA) 1979 lake sampling program. The six lakes, Otter, Lincoln Trail, Pittsfield, Mattoon, Paradise, and Taylorville are ranked for expected water quality based on mean depth, watershed equivalent inches, retention time, and drainage area to storage capacity ratio. To assess water quality, Carlson 's Trophic State Index (TSI) is applied to Secchi transparency, chlorophyll a, and total phosphorus data. Total suspended solids (TSS) and nonvolatile suspended solids (NVSS) are also included. Otter Lake has the best physical characteristics; however, the August 1979 TSI average values show Lincoln Trail with the best water quality, probably as a result of its higher percentage of cropland to woodland. Lake Taylorville ranks fourth on the list because the TSI value for chlorophyll is low---a result of high turbidity and a short retention time. Better water quality is related to long retention time, low watershed area to lake capacity ratio, and greater mean depth, as well as little urbanization, less row crop cultivation, and soils with low fertility and erosivity. As these characteristics become less desirable water quality tends to decline. (Atkins-Omniplan) JF - Proceedings of a Round Table on Reclaiming and Managing Lakes in Illinois October 10-11, 1980.

Cluster analysis of the raw spectral dat established distinctive lake groups, each comprised of water bodies having similar optical and physical properties. The spectral properties of each lake provided an integrated characterization of water quality and related use impairment problems. The trophic parameter estimates, as well as lake clusters and rankings derived from them, were in general agreement with contact-sensed data and with the raw spectral data.

For the most part these permits limited the conventional pollutants: biochemical oxygen demand (BOD), total suspended solids (TSS), oil and grease, pH, as well as ammonia, metals, and phenols. In 1977 the Clean Water Act was passed to focus attention on controlling toxic pollutants. By July 1, 1984, industry is to meet minimum technology requirements, which means the best available technology economically achievable must be used for controlling toxic pollutants, and best conventional pollutant control technology used to control conventional pollutants. Permit issuance procedures have changed little since 1973. The law requires the EPA to consider more stringent limits for conventional pollutants in the second round permits, but such limits will only be imposed where additional required facilities meet a cost-reasonableness test. EPA will review the treatment facilities employed to meet present requirements and then determine what logical modifications or additions might further reduce conventional pollutant levels. Major emphases of new permits will be the control of toxic pollutants. Reductions in pollutants will most likely be achieved by: optimization of existing treatment systems most industries installed to meet current requirements; isolation at the source and separate treatment; process chemical substitution; or housekeeping improvements. Large scale application of advanced wastewater treatment techniques is not expected. (Baker-FRC) JF - Civil Engineering (New York) Vol 51, No 9, p 76-78, September, 1981. 2 Tab.

Mass loadings are usually specified in NPDES permits, and flow data is critical to calculating pollutant loadings from unit concentration. Flows are measured in two ways: instantaneous and continuous. Instantaneous flows must be determined at the time samples are taken for analysis to calculate the pollutants discharged at a particular instant. In a continuous flow measurement system, the flows are totalled to obtain a value for total flow, used to verify NPDES compliance. There are four basic methods for determining flow: weighing the discharge, volumetric methods, sump pumps, and orifice buckets. Flumes, meters, and weirs are the kinds of devices normally employed to measure open channel flow. Other methods include: pitot tubes, head measurement, energy grade line calculations, orifices, nozzles, venturi flowmeters, open-pipe methods, open channel methods, stream gauging, dilution and tracers. Exotic methods sometimes used include: electromagnetic flowmeters, acoustic flowmeters, conductivity cells, hot-wire anemometers, and warm-film anemometers.

According to EPA regulations, trihalomethanes, primarily formed by chlorination of humic materials in raw water, must not exceed 0.10 mg per liter in drinking water. Of the three unit processes--oxidation, aeration, and adsorption--each has advantages and disadvantages. Granular activated carbon, when fresh, is most effective in removing precursors, but this excellent performance is not long-lasting. Clarification, source control, oxidation, adsorption, biological degradation, and pH lowering also significantly lower precursor concentrations. The advantages and disadvantages of alternative disinfectants are discussed. Ozonation is very effective but has no residual action within the distribution system. Chloramines are easy to use and produce residual disinfection but are suspected of being toxic. Chlorine dioxide is very desirable as a disinfectant, but residuals in drinking water may exceed the 0.5 mg per liter limit. Four examples of treatment systems using chlorine as a disinfectant are discussed in detail to illustrate the evaluation process.

About half of all on-site systems fail to perform satisfactorily over their entire design life of 15 to 20 years. Elevated sand mound disposal systems have been used in Pennsylvania, since the soil is generally not suitable for conventional on-site effluent disposal systems. However, about 40 percent of these systems malfunctioned in less than 5 years. Since the malfunctions were associated with observations of surface discharges of effluent, this study investigated the ability of the soil to transmit effluent from an elevated sand mound to the groundwater system. It was assumed that both the infiltration surfaces and the groundwater system were able to accept the effluent. The flow calculation method used was predicated upon separation of the effluent flow into horizontal and vertical flow components. Darcy 's law written in cylindrical coordinates was used to calculate horizontal flow. Vertical flow was calculated, assuming that flow was limited by a single, slowly permeable layer of known thickness. The calculations demonstrate that the lateral plus vertical flow capacity of the soil must exceed the anticipated effluent input if the disposal system is to perform satisfactorily. Data requirements for evaluation of the suitability of a specific site for disposal of household wastewater using a mound system are identified. Calculations made using data representative of many of the failing mound systems in Pennsylvania indicate that these failures result from the inadequacy of the combined lateral and vertical flow capability.

Although wastewater P loading was reduced by 99% and loading from all external sources by 80%, the lake continues to be highly productive, especially during July and August. The source of P was internal, corresponding to internal supply rates of 240-680 kg per week over a 3-9 week interval in summer. The P release took place during anaerobic conditions, the time of which varied from year to year (1971-1975). The P content of the surface sediments was 0.2-0.5% dry weight, and a large proportion was potentially mobile, 27.7 to 72.8% (NaOH extractable). The upper 10 cm of sediments was estimated to contain 50,000 kg of potentially mobile P, enough to supply P to lake water for about 20 years at the present release rate.

Mass increases of 2,000-2,900 kg (35-50 mu g.liter super(1) ) were measured, corresponding to internal supply rates of 240-680 kg.wk super(1) over a 3-9-week interval. After anaerobi: conditions developed in late June, release from the profundal zone sediments contributed significant amounts of P to lake water. Sediment chemical properties were determined to estimate the size of the P reservoir in the profundal zone (at water depths > 6.5 m). The P content of the surficial profundal zone sediments was 0.2-0.5% (dry wt) and a significant fraction was potentially mobile (NaOH extractable). We calculate that the upper 10 cm of these sediments contain 50,000 kg of potentially mobile P, of which a small fraction is released each summer. Although external sources of phosphorus have been reduced by about 80%, the feedback of P from the sediments is supporting the productivity of Shagawa Lake and may continue to do so for many years.

Stream nutrient concentrations were compared in sets of 80 and 175 relatively large watersheds with varied patterns of forest and agricultural land use. The importance of proximity of general land use types to main streams in affecting mean annual stream nutrient concentrations was tested by comparing two models, both considering the land use pattern, but one also taking into account proximity. The results indicate that consideration of the proximity of the land use did not improve the predictive ability. This is partly attributable to the negligible effects of near-stream vegetation in reducing stream nutrient levels.

An extensive table is included which summarizes the acute and chronic toxicity of inorganic and organic pollutants to freshwater fish. Published literature included many reviews and symposia which presented information on water quality, physical and chemical pollutants, and industrial and municipal effluents. These include the aquatic toxicity of Cu, Cn, V, and chlorophenol, and the effects of natural and artificial sources of radiation. Other papers concerned the effects of Hg, the effects of mosquito control agents, and the relationship between biotransformation and toxicity of xenobiotic chemicals in fish. Most of the articles cited deal with the effects of chemical pollutants. Papers are cited which deal with the effects of chlorine and wastewater, and pulp and paper wastes.

Research included an evaluation of the use of granular activated carbon whicch identified needed research including investigation of the factors responsible for the initiation of microbial growth on GAC surfaces and the microbial generation of organic compounds during carbon treatment. A study on the inactivation of cell-associated poliovirus and coxsackievirus found that higher ozone residuals were required than for nonassociated viruses. Also, natural poliovirus isolates found in drinking water were more resistant to chlorine inactivation than were standard laboratory virus strains. One study examined 23 potable water supplies for viruses and found ten virus positive samples. An investigation of water encrustations from seven water systems by scanning electron microscopy found algae, actinomycetes, diatoms, and filamentous and flagellated bacteria. Several studies supported the concept that microorganisms promote a localized corrosion of metal and tubercle formation, and that the microbial ecosystems influence the concentrations of numerous constituents in distributed waters.

Many cases of plant workers exposed to pathogens and chemicals are reported--chlorinated organics, hydrogen sulfide, bacteria, and endotoxins. Several studies done on risk of bacterial and viral exposures for plant workers and nearby populations failed to show significantly higher illness rates. Several papers discussed the hazards of wastewater discharges with respect to swimming, transmission of antibiotic resistance factors, and viruses. Although exposure to sludge composting did not produce a high incidence of illness, protective measures and regular health examination for workers are recommended. Of particular concern is Aspergillus fumigatus. Studies on land application of wastewater and sludges revealed few ill effects in animals fed sludge, crops grown on sludge amended soils, or exposed humans. However, some potential and actual cases of disease transmission were noted: grazing animals, persons living in kibbutzim practicing wastewater spray irrigation, well water pollution, a cholera outbreak, and leptospirosis incidence. Potential chemical threats from land application are pesticides, polynuclear aromatic hydrocarbons, toxic trace elements (particularly Cd), and nitrates. There is not much information on health effects of treated wastewater reused as part of the potable water supply, but it is preferable to use renovated water for nonpotable uses. Of great concern are pathogens and mutagenic or carcinogenic materials, such as halogenated organics, in reclaimed water.

Highest total concentrations (up to 1700 ppb in mussels, <1 ppt in particulates) were found in the highly polluted upper bay, decreasing with increasing distance from the industrial area. In the lower bay, 37 km from Providence, concentrations in particulates were 20 times lower than in the upper bay. Less than 80 ppb were found in mussels 34 km from the upper bay. A potential source of the pollution is a chemical plant which manufactures 2,4,4 ' - trichloro-2 ' - hydroxydiphenyl ether.

Biological monitoring is defined as the use of a living organism to measure, for a specific time and location, the presence or amount of a substance in the environment or in man, or the effect of a substance on the environment or man. The organism may be a naturally present or introduced species in the environment, or in the laboratory, or in a simulated environment or microcosm. Biological monitoring offers great promise for detecting specific chemicals and has the advantages of greater biological relevance, greater sensitivity, and ability to indicate actual or potential exposures. Most of the emphasis has been on monitoring of aquatic systems, but biological monitoring can be applied to air and terrestrial systems.

Although storm water pollutant concentration varies with time and location during a storm and from one storm to another, the BOD5 is usually close to that of municipal sewage secondary effluent, and the suspended solids concentration is similar to that of raw sanitary wastewater. Combined sewer overflow quality lies between that of untreated sanitary sewage and urban storm runoff. Physical treatment units are more effective than biological systems because they can handle the highly variable flow rates and pollutant concentrations. The treatment chosen depends on the desired use: low level treatment for irrigation water and high level treatment for boiler feed water. A table lists four categories of waters, AA, A, B, and C, with the maximum concentrations of metals, anions, color, etc., allowed for each classification. A hypothetical case study of a 100 acre industrial complex illustrates the planning process. After the demand and quality requirements in each category of water quality are decided, storage and treatment facilities are designed for each class of water. Next, costs are determined. Three reuse alternatives are compared: all city water, all storm water except for potable water, and all storm water except for potable water and process water. The cheapest alternative in this case reuses stormwater for irrigation process and cooling water and gives a total water supply cost of $1.54 million, saving $800,000 over the use of city water for these purposes plus for potable water.

Approximately 38 percent of the total state population and 82 percent of the rural populaton relied on an underground water source for drinking water as of 1970. A wide variety of activities can lead to groundwater pollution, includng waste disposal sites; improper well construction; land application of potential pollutants such as fertilizers, pesticides, and road salt; mining and quarrying; individual sewer systems; and transportation of hazardous wastes. Various control strategies are possible. Illinois should (1) examine state agency jurisdiction to identify over laps or gaps in existing regulations; (2) examine the role of non-regulatory and scientific entities in the state to ensure coordination between such programs; (3) increase public awareness of the importance of groundwater as a valuable natural resource and identify existing public values and perceptions of underground water; (4) encourage public participation in program direction and development; (5) utilize the interagency groundwater task force to increase cooperation among involved state agencies on groundwater related strategies, determine the availability of data to decision-makers and identify technological practices; and (6) continue development of a comprehensive groundwater quality management program. Funds and technology-sharing must be sought from the federal government.

Ground water quantity problems can be attributed to cyclic drought conditions. Conflicts between groundwater users have been noted in a number of areas and are usually the result of well interference between two or more large users or one large user affecting water levels in nearby shallow wells. For the most part, the problems have been resolved voluntarily by adjusting pumping rates and schedules, or by developing additional production wells beyond the area of pumping interference. Ohio, being a densely populated and highly industrial state, generates large volumes of both liquid and solid wastes. Based upon groundwater complaint investigations conducted by the Ohio EPA over the past eight years, the most prevalent ground water contamination problems are from domestic on-lot sources affecting private individual wells. Contamination has most often been the direct result of poor well construction and maintenance, or improper well abandonment. Other leading causes of contamination have been salt water effects related to oil and gas production or improperly plugged oil wells, and coal leaching effects. Ohio 's major concerns in ground water program planning are to define agency roles and coordinaton, determine staff capability and training, develop public education and awareness, and increase data collection and regulatory practices.

Water Solubility and the Molecular Fragment Mobility Coefficient AN - 19226707; 8103340 AB - This is the second in a series of studies evaluating the use of various molecular modelling techniques to estimate the mobility of organic chemicals in soils. The objectives of this study were to identify molecular fragments within organic chemicals that may significantly enhance or retard mobility in soils; identify fragments that do not significantly enhance or retard mobility; quantify the fragment effects; and incorporate these effects into the estimation method that predicted mobility from the logarithm of the solubility. Soil thin-layer chromatography was used to quantify the mobility of 55 pesticides, having diverse chemical structures, in Hagerstown silty clay loam soil. Thirteen fragments were identified and divided into two groups. One group of fragments possessed an electronegative or electropositive character whose mobility enhancement or retardation effects were not created by, or were negligibly affected by, aromatic ring resonance. In the second group, ring resonance played an important role in establishing mobility effects. Two least squares multiple regression models, incorporating water solubility and quantifying the surface repulsion or attraction effect as a molecular fragment mobility coefficient, successfully predicted the retention factor. These two models were superior techniques for predicting the mobility of diverse organic chemicals compared to the estimation technique utilizing solubility as the only independent variable.

There are about 11,000 such facilities in the United States. The emphasis of information gathering in this study was on plants with production of more than 93 sq m product per day, which as a group accounts for 1 ,100 plants and 88% of the U.S. production. The toxic pollutants in the plant wastewater are silve, cyanide, and chromium. Silver is present in all wastewater, but cyanide and chromium are only present when the facilities use bleaches containing them. Cadmium may be present in some wastewaters as it is a component of some photographic emulsions. Up to 85% of the silver and cyanide are recovered, using conventional in-process controls, primarily for the economic benefits. Some plants are using advanced in-process controls such as ion exchange, reverse osmosis, countercurrent washing, and wash water recycle, which produce conservation and environmental benefits. There may also be a cost benefit for the larger plants. No facilities are known to regenerate chromium from their wastewater, but treatment systems are available to do so. Pollutant levels in wastewater are given in kg/100 sq m of product, to encourage water saving. The plant mean data, after the basic wastewater treatment, for silver, cyanide, and chromium are 0.14, 4.8, and 0.088 kg/1000 sq m, respectively.

The leachate simulated the high organic strength leachate produced by a young landfill. The specific oxygen utilization rate in the spike system and control system generally paralleled each other with the exception of an increase in the spike system following addition of the leachate. The sludge volume index increased after the first leachate, then declined with the subsequent additions, but during the 400 mg/l COD period the mass of bacteria increased uncontrollably and filled the clarifier. The oxygen demand with 400 mg/l COD was 75 mg oxygen/h compared with 38 mg oxygen/h for the control. The activated sludge process was able to treat a synthetic leachate with COD of up to 200 mg/l but at 400 mg/l the increase in sludge mass and degradation in sludge settling characteristics resulted in the sludge volume overloading the clarifier.

The research activities in these three general areas are classified into five categories: leachate forecasting, controlled decomposition, co-disposal, manuals of practice, and economic assessment. Leachate forecasting includes studies to predict volume and composition of leachates, gas production, and their migration and management. Controlled decomposition is intended to control the quality and volume of leachate production by altering the decomposition processes, controlling waste leachability, and use of liners/membranes/admixtures. Studies are being conducted on co-disposal of municipal wastes with industrial and sewage sludges, with leachate quality control or recirculation. Manuals of practice are being developed concerning the environmental impacts of special types of landfills, sampling and preservation of groundwater, and the use of gas barriers and growth of trees on closed landfills. An effort is being made to evaluate the relative importance of the various factors affecting the costs of sanitary landfills, in order to identify the least costly disposal alternative under local conditions.

A major objective of the Monitoring and Data Support Division Study was to determine the relative significance of the major source types- residential, commercial and industrial - in contributing priority toxic pollutants to POTW influents. The collection systems from eleven residential areas, ten commercial areas, and five industry-dominated areas in four different cities were sampled. The influent to the POTW and tap water were also sampled. All of the 129 priority pollutants were looked for, but 67 were not found in collection systems of four POTW's. The most prevalent pollutants detected were metals, solvents, and phthalate ester plasticizers. Industrial sources appear to dominate the loading on the POTW for most pollutants, while residential and commercial contributors are still important for some pollutants, although at a lower total loading when industrial sources are not present. The type and size of industry present was a significant factor in detecting the presence and concentration levels of the priority pollutants.

Those materials analyzed include semivolatile organic priority pollutants and the heavy metals. The basic approach in this project is to operate parallel sequences of the unit processes. One treatment train is operated as a control; the other sequence has the organic compounds being studied added in a toluene solution. The initial spiking provides a concentration of 50 micrograms/L for most of the organic compounds being studied. All process flows, sludges, and off-gases are sampled so the behavior of the spiked chemicals and indigenous metals can be quantitated. Although not enough tests have been completed to provide definitive data on removal of these materials, especially metals, initial findings are that recoveries of organics range from 70 to 90% for the PAH's, from 70 to 100% for the phthalates, from 95 to 100% for phenols, and from 90 to 100% for the pesticides.

Included are discussions of the pretreatment requirements in the Clean Water Act of 1977, EPA 's general pretreatment regulations, and the procedure used to establish categorical pretreatment standards. Significant problems (addressed by the Clean Water Act of 1977) caused by discharges to publicly owned treatment works (POTW) include interference with POTW operations (fires, corrosion, explosions, hazardous fumes, system upsets); incompatibility, such as interfering with sludge disposal; and the passage of discharges through POTW. Categorical pretreatment standards are based on the degree of treatment that can be obtained by different technologies, considering the economic impact of those technologies. The philosophy behind establishing uniform categorical pretreatment standards is that all industries in a category, or subcategory, should have to treat their wastewater to the same degree of treatment.

A summary of THM regulations lists the monitoring and reporting requirements. Exposure may be minimized by using disinfectants which do not generate THMs in water, by reducing precursor concentrations prior to chlorination, and by removing THM after formation. Average annual costs per residence for removing excess THM from regulated systems (serving more than 10,000 people) are estimated at $1.40. Two surveys of drinking water in 80 and 113 cities respectively revealed an average total THM concentration of 0.053 to 0.117 mg per liter. Chloroform was found in the largest amounts, up to 75% of total THM. Most chloroform toxicity and metabolism studies have used high doses; mammalian responses include central nervous system effects and damage to kidneys and liver. Chloroform-induced teratogenesis and carcinogenesis have been reported, and similar studies on the brominated haloforms are underway. Although the levels of THM in drinking water are generally very low, it is not difficult or expensive to reduce the contaminant levels. The goal is to provide drinking water as free of adulterants as technology permits. (Cassar-FRC) JF - Environmental Science and Technology Vol 15, No 3, p 268-274, March, 1981. 6 Tab, 25 Ref.

The most familiar types of assistance are those activities specifically directed toward problem areas, such as technical assistance, demonstration projects, contracts and studies, and emergency assistance. State and regional offices of the Environmental Protection Agency (EPA) have many programs designed to assist communities in complying with the Safe Drinking Water Act and to provide technical assistance. Other activities of the EPA include demonstration projects, the Model State Information System, and the National Rural Water Association Training and Technical Assistance Program. Regionalization and consolidation of water system planning and operation is being encouraged both to realize economies of scale and to concentrate water supply talent. The development of junior college curricula in water treatment technology and water treatment instructor education is also being encouraged. State programs include innovative techniques for settling priorities and distributing available funds to water supply systems and acceptance of Primary Enforcement Responsibility, with attendant grant funds from EPA.

Detection of the particulate organic carbon of the plume and maximum oxygen demand would be restricted to the top 50 m of the surface layer within 15 km of the ship. Reduced oxygen concentrations in the benthic layer would be an undetectable consequence of the oxidation of the macerated and smothered bottom fauna.

Grob uses carbon disulfide to elute the organics off the activated carbon and gas chromatography to separate the organics in the eluent. The Grob CLSA method is a vapor-phase stripping method by which those compounds with appreciable vapor pressures over water are removed from the sample by purging it with a large volume of gas and passing the stripping gas through an adsorption tube. Unlike other vapor-phase methods, this method has achieved a millionfold concentration of most low and intermediate molecular weight organics by using a closed-loop design. In the process, 0.5 liter of stripping gas is recycled continuously through the water sample, and the adsorption trap is extracted with 10 microliters of carbon disulfide. Quantitative analysis is achieved by spiking the initial water sample with a series of internal standards, by stripping at 30 degrees for two hours, and by chromatographing the carbon disulfide extract on a WCOT (GC) column. The method may be employed for monitoring, for analytical steps in epidemiological studies, for granular activated carbon evaluation, and in recovery studies.

The study also aimed to identify treatment procedures and operational problems that might allow cysts to pass through filters and to discover the cyst removal capabilities of well-operated filters. The studies suggest, through the use of cyst models, that properly operated water filtration plants should remove a high percentage of Giardia lamblia cysts. In order for effective cyst removal to occur, diatomaceous earth filters need 1.0 kg sq m diatomite precoat plus body feed, and granular media filters need coagulation of raw water and production of filtered turbidity well below 1.0 normal turbidity units throughout the entire filter run.

General cost characteristics of chlorination and alternative methods of disinfection; a comparison of costs among disinfectants at presumed equivalent dosages; and a comparison of energy utilization among alternative disinfection processes are also discussed. A comparison is made of the costs and benefits associated with the alternative disinfectants on a common basis. The analysis presented is based on the records of the Cincinnati Water Works and the Hamilton County, Ohio Health Department. The study demonstrated that disinfection and the combination of disinfection and filtration are highly cost-effective preventive public health practices. When various disinfectants are compared on the basis of dosage and energy comsumption, chlorine is probably the cheapest disinfectant. In terms of incremental dosage, chlorine has the lowest marginal cost per unit increase in concentration. The costs of other disinfectants are only slightly higher, however, than that of chlorine, and disinfection on any basis shows a favorable cost-benefit relationship.

While the quality of urban stormwater varies greatly from metropolitan area to metropolitan area, the biochemical oxygen demand is close to that of secondary treatment plant effluent and the suspended solids concentration is similar to that of raw sanitary wastewater. Because there is high volume variability with stormwater and combined sewer overflow, physical treatment units are generally better than biological ones. A treatment system is designed with the final water quality desired in mind. The sample stormwater reclamation system included a storage reservoir and treatment facilities. Treatment included: fine mesh screening, chemical addition, high rate filtration, disinfection, and carbon columns. A system using a combination of city water and reclaimed stormwater would save approximately $900,000/year over a system using only city water. Reclaimed urban stormwater can be used for industrial subpotable water.

It includes the relationship of transmission costs to the problem of serving spatially distributed demand. It is possible to find a point at which the partial differential of the average cost function with respect to distance is zero, yielding a system size for minimum cost. Although the per capita consumption and absolute levels of population density have little effect on least cost system size, the minimum cost solution is very sensitive to population distribution. These insights can be used in planning water systems, especially regarding efficient utility size and alternatives for outlying areas.

AN - 74012022; 15622729 AB - The behavioral effects of both acute and subacute triethyltin (TET) exposure were examined in the rat. Animals acutely exposed to TET at doses of 0, 1.5 and 3.0 mg/kg showed a dose-related decrease in motor activity when tested between 2 and 4 hr following exposure. Subacute (3 week) exposure to TET in the drinking water (5 or 10 ppm) resulted in performance decrements in the following: maze activity, open field behavior, acoustic startle response and landing foot-spread. Early signs of behavioral deficits were observed 2 weeks after 10 ppm TET. These effects were reversible within one month after termination of exposure.

AN - 73960183; 15622726 AB - The activity of tyrosine hydroxylase (TH) was measured in homogenates of hypothalamic tissue and corpus striatum obtained from 24 day old rats. The addition of manganese to the preparations had no direct effect on TH activity in either brain region. Similarly, the addition of calcium, magnesium and lead at concentrations of 1.0 mM did not affect TH activity. Cadmium and zinc (1.0 mM) significantly reduced TH activity in both the hypothalamic area and corpus striatum. Iron (1.0 mM) significantly stimulated TH activity in the corpus striatum but did not affect TH activity in the hypothalamic area. At conentrations of 1.0 mM, neither disodium ethylenediamine tetra-acetic acid (EDTA) nor ethylene glycol bis (beta-amino-ethyl ether)-N,N'-tetraacetic acid (ECTA) affected directly TH activity in either brain region. Cyclic adenosine 3',5'-monophosphate (cAMP) at a concentration of 1.0 mM did not affect TH activity in either the hypothalamic area or corpus striatum. Results from these in vitro studies show clearly that manganese does not inhibit directly TH activity and that manganese does not compete with other physiologically important divalent cations to cause the reduction in TH activity seen in vivo after chronic exposure.

AN - 73921026; 15622725 AB - Male rats were exposed to manganese at doses of 1, 10, and 20 microg/g body weight/day from birth to day 24 post-partum. Animals were weighed and examined daily. The animals showed no visible signs of toxicity and exhibited normal weight gain. On day 25 the animals were killed by decapitation and the hypothalamic area and corpus striatum were removed and analyzed for several neurochemical components. Chronic manganese administration (10 and 20 microg/g) caused a significant reduction in the concentration of endogenous dopamine in the hypothalamic area. The concentration of endogenous norepinephrine in the hypothalamic area was unaffected at all levels of manganese administration. The depletion of dopamine induced by alpha-methyl-p-tyrosine was less in the hypothalamic area of chronic manganese-treated rats suggesting that dopamine turnover was reduced. No significant changes in neurochemical components occurred in the corpus striatum. Manganese at a dose of 20 microg/g caused a significant decrease in hypothalamic tyrosine hydroxylase activity and a significant increase in hypothalamic monoamine oxidase activity. The dosing regimen of 10 and 20 microg/g caused a significant elevation in tissue levels of manganese in both the hypothalamic area and corpus striatum. The results of this study indicate that minor alterations in the manganese content of the developing rat brain can lead to neurochemical alterations in specific brain regions.

Environmental factors seem to be the most important determinants of the initial population sizes. A general management strategy is proposed, which is consistent with the environmentally controlled occurrences of dominant year classes, and which also optimizes benefits from the fisheries. Because the relative importance of biological and abiotic population controls is uncertain, the proposed management strategy also strives to protect the reproductive potential of the striped bass stocks. This biologically based strategy can be implemented in the form of regulations that are flexible temporally and geographically.

Since 1970 the fastest population growth has been in rural areas, not in the cities. People are moving out of the largest cities in substantial numbers into counties with the lowest population densities. Rural planning capabilities and land use controls, where they exist, cannot anticipate or regulate the rapid pace of new development. Further, rural fiscal resources often cannot meet the demands for such public services as sewers, schools, medical facilities, police and fire protection, which are created by new residents. The many tasks confronting municipalities experiencing population increases include planning sewage treatment improvements - expansions or entirely new systems. One of the first tasks in the planning stage should be the development of a sludge management program. The end product of the wastewater treatment operation should be dealt with at the very beginning of the planning process. Municipal sludge treatment and handling should be an issue of public decision-making and should be brought out of the conference rooms of sanitary engineers and contractors who have been trained in designing and building bigger and better treatment systems. In these communities there have to be citizens trading ideas about what kind of future sludge management programs are best for their area.

EPA takes a great interest in the environmental implications of the manufacture of synthetic fuels , including coal liquefaction and gasification, retorting of oil shale, and the production of alcohol for fuel. Interest is also expressed in geothermal, solar, wind and tidal energy, combustion modification, coal and oil shale mining, energy conservation, fuel and energy transport and transmission, and new energy conversion systems such as ocean thermal gradients, magnetohydrodynamics, and fuel cells. In the area of pollution control guidance, the focal point of each regulation is intended to be a set of available control alternatives for each environmental discharge along with associated performance expectations and the basis for the alternatives presented. For most of the new energy technologies, exemplary full-scale and even pilot-scale waste treatment installations do not yet exist. A novel possibility now available is that of influencing in an environmentally productive way the choice by industry of the actual process technology to be commercialized and the overall designs of new plants, such that the most cost-effective environmental protection methods can be incorporated into the process design from the start. Specific energy technologies for which pollution control documents are now planned include low Btu coal gasification, indirect coal liquefaction, oil shale mining and processing, direct coal liquefaction, geothermal, medium Btu coal gasification, and high Btu coal gasification.

The application of ecological models to the Lake Michigan basin was the central focus of this research. A modified version of a deterministic phytoplankton mode, Lake 1 by Thomann, was first calibrated to the 1976 Lake Michigan field data. A dynamic phytoplankton simulation model (MICHI) was developed to investigate the observed field data and to use in forecasting lake responses to various phosphorus loading scenarios. The 1977 data indicated that the southern basin of Lake Michigan lost up to 3 micrograms of phosphorus per liter compared to concentrations observed in 1976. In an attempt to simulate this rapid depletion of phosphorus, MICHI required an implicit representation of suspected effects of an extensive ice cover observed during the winter of 1976-77. This included increasing the net apparent settling rate eight fold during ice cover. A total phosphorus model was used in conjunction with MICHI for forecasting. These forecasts indicate a steady-state total phosphorus concentration of 7 micrograms phosphorus per liter, given the target load recommended by the 1978 Water Quality Agreement. The projected time to obtain 95% of steady-state response to a load change was 7-14 years. (Baker-FRC) JF - Journal of Great Lakes Research Vol 7, No 4, p 467-480, 1981. 10 Fig, 3 Tab, 43 Ref.

The multi-class phytoplankton simulation model was set to field data acquired on Saginaw Bay, Lake Huron, during 1974. The concept of a single limiting factor for phytoplankton growth was found to be overly simplistic. Results indicated that temperature and light were relatively more growth rate limiting than nutrients on an annual average bases. However, as a consequence of nutrient depletion, nutrients became relatively more important at the times of peak phytoplankton crops. Nitrogen was more growth rate limiting than phosphorus to the total phytoplankton crop, although important differences occurred among the individual functional groups. While nitrogen and silicon were important in phytoplankton-nutrient dynamics, the supply of phosphorus would ultimately determine the size of the blue-green component of the total crop because nitrogen fixing blue-greens did not have absolute requirements for dissolved available nitrogen or silicon. Phosphorus requirements for summer crops were satisfied by recycle processes within the water column. Phytoplankton production was extremely sensitive to variation in the light extinction coefficient in the water column and relatively insensitive to variations in incident solar radiation.

Biodegradation of toxic chemical substances is best described by Grau kinetics. An estimate of mass transfer coefficients in air stripping can be obtained from the ratio of the diffusion coefficient, molecular weights, or critical volumes in conjunction with a known value of the mass transfer coefficient. Sludge adsorbs some priority pollutants, primarily polynuclear aromatic compounds, metals, and cyanides. The disappearance of a specific toxic pollutant in sludge in nonbiodegradable form can be represented by the multicomponent adsorption equation of Langmuir type based on the binary characterization of wastewater adsorption.

Viruses used were poliovirus (Sabin Type 1), coxsackievirus A9, and the f2 bacteriophage. Escherichia coli was treated under the same conditions as the virus--unadsorbed or adsorbed on 1 and 5 turbidity units (TU) of bentonite clay (particle size 3-8 mm), up to 0.53 mg per liter ozone, temperature 20 C, pH 7.0, and inactivation times of 10, 20, and 30 sec. Poliovirus, coxsackievirus, and E. coli associated with clay were inactivated at rates similar to the freely suspended organisms. The f2 bacteriophage was inactivated at a slightly slower rate than freely suspended phage. Typical results obtained were: 5 TU adsorbed poliovirus (140 plaque forming units (PFU) per ml), 0.016 mg per liter ozone, > 97% inactivated within 20 sec; 5 TU adsorbed coxsackievirus (220 PFU per ml), 0.019 mg per liter ozone, > 98% inactivated within 20 sec; 5 TU adsorbed f2 bacteriophage (15,000 PFU per ml), 0.061 mg per liter ozone, > 98% inactivated within 20 sec; 5 TU adsorbed E. coli (180 million CFU per ml), 0.038 mg per liter ozone, > 99% inactivated within 10 sec.

Data obtained from intensive pollutant sampling in the Grand River, flowing into Lake Michigan, were used as a comparison. On the basis of the root mean square error the best method was the unbiased stratified ratio estimator, recommended for use when concentration data are limited and daily river flow records are available. Other methods evaluated were five simple methods based on daily, monthly, quarterly, semiannual, and annual average concentrations. The complex methods generally were more adequate. These were based on concentrations from quarterly, semiannual, annual, and stratified regression on log flow. Accuracy was increased by including more samples from the high flow periods.

OWRT is charged with ' assuring an adequate supply of water of good quality for the nation 's needs through water-related research and practical application of R and D results. ' OWRT supports 54 water research centers and a focused research program; it also operates the Water Resources Scientific Information Center. Nonpoint pollution research is needed to identify the source, amount, and impacts of the pollutants entering our water resources from a variety of land use activities. A knowledge of the fate and cycling of nitrogen and phosphorus is needed along with more information about the fate and pathways of the over one billion pounds of pesticides manufactured in the United States every year. Other nonpoint pollution research areas include environment transport analysis, the limits of environmental protection, application methods, marshes and wetlands as barriers to contamination, erosion and sediment control, and acid rain. Research is the key to the solution of nonpoint pollution problems.

Disinfection rates are compared in terms of the times and concentrations required to achieve a specified degree of inactivation (e.g., 99%) of a given microorganism. Overall, ozone is the most efficient and least stable agent; chlorine dioxide is second in efficiency and stability; free chlorine is third in efficiency and stability, and chloramines are least efficient and most stable. Inactivation kinetics for E. coli, poliovirus 1, cell debris-associated poliovirus, and coliform bacteria are graphed for all the agents except ozone, which operates too quickly for convenient plotting. Ozone has been shown to effect greater than 99.999% reduction of E. coli in 10 sec at an initial concentration of 0.38 mg/l, and 99.7% reduction of poliovirus 1 in 10 sec at only 0.012 mg/l. The biocidal action of ozone and chloramines was only slightly affected by pH in the pH 6-9 range; that of chlorine declined rapidly as pH rose from 7-9, and that of chlorine dioxide rose as pH increased. The effects of particular microorganisms and dissolved salts on biocidal efficiency are also discussed. Laboratory studies simulating field conditions indicate that turbidity can shield microorganisms from disinfectants: e.g., viruses suspended with cell debris are protected from ozone. There is not yet sufficient information to recommend the replacement of chlorine with other disinfectants.

Data are being gathered from many sources to be used in a predictive model. Point source information from municipal and industrial sources is being synthesized from existing EPA and State and agency files. LANDSAT data will be used to perform land-use analyses to develop nonpoint source runoff projections. Fall line monitoring on the Susquehanna, Potomac, and James Rivers will provide data on suspended sediments, nutrients, metals, pesticides, fresh water discharge, and other physical and chemical parameters. Nonpoint monitoring programs are being conducted in the Occoquan and Ware River watersheds and in the Pequea Creek basin. The Hydrologic Simulation Program in Fortran has been selected for modeling of the non-tidal drainage basin of the Bay. Following verification of the model, it will be used to produce time series output of current and future loadings, land-use patterns, and input for a Bay-wide water quality model at the tidal Chesapeake.

Regulations finalized by EPA on November 29, 1979, set forth a maximum contaminant level of 0.10 mg/l for total THMs, and require monitoring and reporting of THM levels at quarterly intervals. Control strategies include use of a disinfectant that, unlike chlorine, does not generate THMs (chloramines, chlorine dioxide, ozone), reduction of THM precursors prior to chlorination, or reduction of THMs after formation. By 1977, ozone was the perferred disinfectant in more than 1039 water treatment plants, mostly in Canada and Europe. Ozone is a more effective disinfectant than chlorine, does not produce THMs, and can also be used to remove THM precursors prior to conventional chlorination. Precursors can be removed by direct ozonation or by using ozone to improve the removal efficiency of coagulation, settling, or filtration units. A summary of data from pilot studies showing THM precursor removal efficiencies of up to 80% is presented. Disadvantages of ozone compared to chlorine include limited residual disinfectant protection (sometimes leading to aftergrowth problems), higher costs, and the potential for forming organic byproducts with unknown health risks. Consideration of ozone 's ability to remove THM precursors while improving the efficiency of other unit processes is likely to reduce its price disadvantage.

New initiatives are being taken in this area by Congress, the Environmental Protection Agency (EPA), the Agriculture Department, the Department of Interior, and other Federal agencies. EPA 's Section 208 and its grant funds are aimed directly at nonpoint pollution with emphasis on urban runoff, agricultural runoff, and groundwater contamination. EPA has developed the National Urban Runoff Program to prepare a data base on the costs and impacts of urban runoff pollution and controls. Thirty prototype projects to test control methods are being supported by Section 208. Initial 208 plans indicate that agricultural runoff is the most widespread cause of nonpoint pollution. Government agencies are aiding farmers and ranchers in the implementation of best management practices. Groundwater protection research is being funded as part of the Water Quality Management Program. The understanding of a wide range of public agencies and public interest is needed for success in nonpoint pollution control.

These 21 impoundment sites were selected by the House Subcommittee as having a high potential for contaminating local ground-water resources, as they are located in close proximity to the tops of highly permeable aquifer systems, thus allowing leakage or direct infiltration of wastes into the ground water; the waste waters in these impoundments may contain chemical substances classified as hazardous; there are no artificially placed barriers or liners beneath these impoundments; the sites are within one mile of a potential water supply well; and a very small percentage of industrial impoundments nationwide are being monitored for ground-water quality effects. These 21 industrial complexes include chemical companies, steel corporations, asphalt companies, incineration plants, a scrap lead plant, and other industrial classifications. The results of individual studies conducted at each of the impoundment sites are presented.

A survey of 19 municipal and 17 recreational package water treatment systems produced the following performance data: pH, 6.5-8.6; coliforms, present in 3 of 31 systems; turbidity, 8 of 31 exceeding maximum federal standards; trihalomethanes, 5 of 31 exceeding 0.10 mg per liter; pesticides, none; silver, 2 systems; mercury, less than 0.001 mg per liter in several plants and 0.020 mg per liter in 1 municipal plant. Most aberrations in performance were ascribed to operator inattention or intermittent operation. Most package plants serve populations of 10,000 or less and have a capacity of 1.5 mgd or less. Comparative costs of a 1 million gallon per day conventional plant versus a package plant showed that the package plant was more economical. Construction costs for a conventional plant were $1,120,000 and annual operating and maintenance costs, $63 ,000; package plant, $488,000 and $40,000 respectively.

The procedure uses purge- and trap sample concentration followed by GC/MS analysis. Data reduction is performed by a computerized GC/MS data system. The quantification limits, precision and accuracy of these analyses have been demonstrated to be comparable to gas chromatography coupled with electrolytic conductivity and flame ionization detection. The analytical scheme permits the routine qualitative and quantitative analysis of 16 commonly occurring purgeable compounds over a concentration range of 0.1-0.2 to 0.5 micrograms/liter. Additional compounds can be analyzed by incorporating appropriate analytical standards.

Samples were analyzed for total organic carbon (TOC) using the Dohrmann TOC system. Three analyses were conducted for purgeable halogenated organics: instantaneous trihalomethanes (THM), simulated distribution THM, and THM formation potential. Response profiles from capillary column gas chromatographic analysis of influent and effluent samples from operating GAC beds were used to qualitatively judge adsorber performance. TOC results can serve as an operating guide at a given location if proper relationships can be established with TOC levels and concentrations of other substances. GAC reduced the simulated distribution THM concentrations and organic halogen levels, but the performance of the GAC system varied with changing influent conditions. Other drawbacks of the organic analysis of GAC performance include the requirement for subjective interpretation of some outputs and difficulties in managing large amounts of data.

In 1977, the Office of Water Research and Technology (OWRT) of the U.S. initiated its Water Reuse Research and Development Program by conducting a comprehensive national analysis of reuse and potential throughout the U.S. This study indicated that a high potential for both municipal reuse and industrial recycling exists in the U.S. The OWRT also evaluated existing treatment technology for applicability in reuse systems. The role of state agencies in implementing an effective wastewater reuse research program includes determining wastewater reclamation research needs, assessing the status of world-wide wastewater reclamation research, establishing a list of high priority research areas for funding priority, and working cooperatively with federal agencies involved in water reuse. Projects involving beneficial reuse of wastewaters that result in reduction of wastewater discharges and utilization of nutrients, organic materials or pollutants should merit funding support at least equally with single purpose pollution abatement projects.

An inert gas is bubbled through the sample. Those organohalides and other organic constituents which boil at less than 200 degrees C, are removed from the aqueous phase and trapped in a short column containing a sorbant combination. After a predetermined time, the trapped components are thermally desorbed, backflushed onto the head of a gas chromatograph and separated under programmed conditions. Measurement is done with a halogen-specific detector. The method is useful for determination of carbon tetrachloride, 1,2-dichloroethane, tetrachloroethylene, 1,1 ,1-trichloroethane, trichloroethylene, vinyl chloride, and 44 additional halogenated compounds listed in a table. The method, useful for detection and measurement of multicomponent mixtures spiked into carbon filtered finished water and raw source water at concentrations of 0.20-0.40 micrograms per liter, has detection limits of < 0.01 micrograms per liter. The compounds listed in the table can be accurately measured over a concentration range of 0.10-5.0 micrograms per liter. Individual organohalides can be determined at concentrations up to 1500 micrograms per liter. JF - EPA Report No. 600/4-81-059 1981. 50 p, 7 Fig, 4 Tab, 3 Ref.

The wastewater samples are screened for organics by analyses of five fractions: pesticides (26 compounds), base/neutrals (46 compounds), acids (11 phenols), purgeables (29 volatile organics), and direct aqueous injection (2 compounds). Except for purgeable organics, overall recovery decreases and the relative standard deviation increases in going from the method standard to the matrix spiked analysis. Analysis of purgeable and acid organic compounds produces the highest recoveries with the smallest matrix effect. The analysis of base/neutral compounds and pesticides gives the lowest recoveries because they react among each other and with hydroxide and water. Base/neutral compounds also carry over into the acid fraction in the presence of emulsions. Analysis of purgeable organics by the EPA protocol has been most successful; acid and pesticide analyses, moderately successful; and base/neutral analysis less successful, especially with samples from the leather tanning and timber industries. Metals analyses are not difficult at the 25 ppb level used. Analyses of several compounds presented problems and are recommended for further investigation: dichloromethane, bis(chloromethyl) ether, N-nitrosodimethylamine, di-n-butylphthalate, bis(2-ethylhexyl) phthalate, 1,2-diphenylhydrazine, benzidine, hexachlorocyclopentadine, endrin aldehyde, anthrene and phenanthrene, chrysene and benzo(a)anthracene, and benzo(b)fluoranthrene and benzo(k)fluoranthrene.

AN - 15553756; 402872 AB - Since arsenic is a significant compound of ores processed in the nonferrous metals industry, it is of interest to characterize and evaluate control strategies which have demonstrated the potential for lowering the emission rates of arsenic and other hazardous effluents from smelter operations. The Campbell Red Lake Mines Gold Smelter at Balmerton, Ontario, Canada, has developed and implemented a successful control strategy for arsenic emissions from a nonferrous smelting operation. The control system was designed and installed by Hatch Associates, Toronto, Canada. The Red Lake smelter uses cyclones and a hot electrostatic precipitator to recover metal values from roaster dusts with subsequent air quenching to condense (or desublime) arsenic trioxide which is recovered in a low-temperature baghouse. This paper is a review of a test program conducted at Red Lake designed to characterize the control systems and to evaluate the potential for transferring the technology to smelting operations in the United States.

AN - 15542767; 396524 AB - A 566 m super(3)/m permanent installation demonstration system, consisting of the Air Pollution Systems' High Intensity Ionizer and a variable throat venturi scrubber has been installed on a magnesium recovery furnace. The furnace produces submicron fume particles of MgO, MgCl sub(2), and ZrCl sub(4). The system is designed to demonstrate the effectiveness of the High Intensity Ionizer versus high venturi pressure drop on the furnace emissions. The High Intensity Ionizer array operates stably at field strengths of 10-15 kV/cm and at velocities in excess of 18 m/sec while maintaining high charging efficiencies. The report covers the system design, technology, applications, and project developments. An Environmental Protection Agency proposed charged droplet Scrub-E is also discussed covering the design, technology, and proposed demonstration program.

AN - 15518031; 349201 AB - Accurate estimates of pollutant loadings to the Great Lakes are required for trend detection, model development, and planning. On many major rivers, infrequent sampling of most pollutants makes these estimates difficult. However, most large rivers have complete daily flow records available from the U.S. Geological Survey. A number of different estimation methods have been developed to use these data in conjunction with available concentration data to calculate pollutant loadings. Several of these methods have been evaluated in this paper for a typical major tributary. Intensive measurements of pollutant loadings to Lake Michigan from the Grand River in 1976-1977 were conducted by USEPA, Region V. Daily concentrations of several chemical parameters, including total phosphorus, were determined. This information, together with daily river flow rates from USGS, provide an excellent data set for testing various load estimation methods. Ten different methods were tested using 680 randomly generated 25-sample subsets of the daily total phosphorus data set. The methods tested included several simple calculation schemes, as well as flow-concentration correlations and the stratified ratio estimator. The latter method is shown to be at least slightly better than the others for these data and for this type of sampling, including when sampling is concentrated during periods of high flow.

AN - 15497616; 321674 AB - The Clean Air Act, as amended in 1977, requires periodic review and revision of all national ambient air quality standards (NAAQS) to insure that they are based on the latest scientific information. A possible framework for analyzing health risks associated with attainment of alternative NAAQS is described. The framework consists of three phases of analysis for supporting future regulatory decisions on NAAQS: (1) a scientific assessment phase, (2) a risk assessment phase, and (3) a risk evaluation and decision analyses phase. The proper separation of roles among scientists, risk analysts, and decision analysts is also addressed. The author concludes that despite several possible pitfalls, the adoption of formal risk analysis approaches can greatly facilitate communication between scientists and decision makers and decision makers and the public in areas involving scientific uncertainties.

AN - 15496353; 327952 AB - The National Park Service and the U.S. Environmental Protection Agency are cooperatively conducting ongoing studies of human perception of visual air quality. Major objectives of this program include: (1) determination of the relationship between judgments of visual air quality of actual three dimensional scenes and a surrogate slide representation of that scene, (2) examination of the effect of sun angle and meteorological conditions on perceived visual air quality, (3) examination of the effect of demographic background on observer's judgments of visual air quality, (4) establishment of a functional relationship between human perception of visual air quality and various electro-optical parameters for several different scenic vistas and (5) development of a model capable of predicting the sensitivity of a park to visual air pollution impact. Preliminary results of a previous study involving one vista revealed a linear relationship between human perception and apparent vista contrast for constant vista illumination and ground cover. A more general formalism for averaging vista color contrast appeared to account for effects that snow cover and varying illumination have on the sensitivity of perceived visual air quality to air pollution.

AN - 15488145; 294887 AB - This paper evaluates from an ex post perspective the economic viability of a pilot irrigation project in northern Senegal which has been in operation since mid-1975. The authors begin by presenting the international context within which the Nianga Project developed, namely, the donor agencies were called upon to fund additional tertiary (i.e., full water control) irrigation projects in the Senegal River Valley in the absence of any rigorous economic analysis of this type of irrigation project. Next, they briefly describe first the project milieu and then the development and operation of the project itself. From the descriptive they pass to the analytic mode, wherein the project is formally evaluated with the techniques of social cost benefit analysis (SCB); and subsequently, they compare the ex ante feasibility study and the present ex post analysis. Finally, on the basis of the results from the latter, they draw some policy implications for future irrigation development in the Senegal River Valley. JF - J. DEVELOP. AREAS.

AN - 15484325; 294886 AB - In discussing an approach to assessing the health risks that would obtain if various possible primary national ambient air quality standards were met, it is important to distinguish appropriate principles for probabilistic risk assessments from principles for the scientific research and scientific assessments on which they are based. Appropriate principles for probabilistic assessment are derived from the ultimate objective of maximizing the amount of control societal decision-making agents have in making environmental trade-offs under uncertainty about the effect of their decisions. A general methodology is presented which implements these first principles. Two general risk models are presented: a relatively simple benchmark risk model and a more complex head count risk model. These general risk models serve as a guide for the development of specific operational risk models applicable to particular ambient pollutants. Examples are given of different specific models needed for different types of pollutants. Since the scale on which a specific methodology is implemented is not determined by the methodology, the various choices involved in deciding the scale of a specific application are addressed.

AN - 15464158; 271221 AB - EPA's airborne downlooking dye lidar was operated during the STATE field program in western Kentucky/Tennessee in the summer of 1978. In this paper, lidar estimates of height of the atmospheric mixing layer are shown and compared with in situ measurements. Lidar estimates of crosswind and vertical dimensions of TVA power plant plumes are compared with appropriate literature values and with in situ estimates from data compiled by other STATE investigators; wherever necessary, data are adjusted to ensure compatibility with respect to sampling time.In addition, lidar measurements of plume rise are compared with model calculations. The lidar estimates of mixing layer height were usually slightly higher than in situ counterparts, presumably because aerosols may rise and become trapped above the base of the elevated stable layer. Values of plume rise computed using the Briggs models were generally similar to those indicated from lidar measurements although considerable scattering of data existed; supplementary data indicated that the scatter could be reduced with the inclusion of the vertical shear of the horizontal wind in the models.

AN - 15453791; 268587 AB - N-Methyl-4-aminoazobenzene (MAB) is believed to be metabolized in the liver to an electrophilic N-sulfonyloxy ester which binds covalently to cellular macromolecules, resulting in the induction of hepatic neoplasia. Since a single dose of MAB is not sufficient for complete carcinogenic activity, the authors sought to identify the MAB-DNA adducts present in rat liver after multiple oral doses of ( super(3)H) MAB. The MAB was administered by intubation at a level of 0.2 mmol/kg for 1, 3 or 4 doses and animals were sacrificed at 8 h after the last dose. Hepatic DNA was isolated by extraction and hydroxylapatite chromatography and was enzymatically hydrolyzed to MAB-mononucleoside adducts, which were quantitated by high pressure liquid chromatography (HPLC).

AN - 15447489; 251898 AB - The reductive dechlorination of dieldrin and endrin was investigated as a possible procedure for field disposal of small quantities of these pesticides. The objective was to convert the parent compounds to environmentally less objectionable materials. Emulsifiable concentrate formulations of the pesticides in a soil slurry were mixed with powdered zinc, dilute acetic acid, and acetone to facilitate reaction. Analysis of the mixtures by GC-MS indicated essentially complete conversion of endrin and partial conversion of dieldrin to products probably formed by replacement of the bridge anti chlorines with hydrogen. Partial confirmation of the desired anti dechlorodieldrin product was made by nmr. Disappearance of the parent compounds and production of conversion products was monitored for 1 1/2 years by GC in an outside soil plot, and accelerated destruction of parent compounds was achieved by the treatment. By analogy to the bridge anti dechloro products of aldrin and isodrin, the anti dechloro products probably are much less toxic than the parent compounds and are therefore environmentally less objectionable.

AN - 15432323; 250692 AB - The U.S. Environmental Protection Agency, National Park Service, Visibility Research Center, and University of California at Davis are currently operating a monitoring program in national parks and monuments throughout much of the western United States. Project VIEW, the Visibility Investigative Experiment in the West, includes measurement of visibility parameters using manual telephotometers, and measurement of particle concentrations averaged over 72 h. Variation of these parameters occurs in both space and time. To better understand these variations, several techniques including principal component analysis and data comparisons among sites are applied to Fall, 1979 data for much of the network. Then the Grand Canyon is chosen for additional analysis. Best and worst case visibility days are determined and compared with particle concentrations. Finally, hypothetical causes for visibility reduction are further verified by computing wind trajectories back in time for these special case days.

AN - 15430289; 236751 AB - This study was designed to assess the effects of diesel exhaust on the development of the nervous system in rats as measured by somatosensory and visual evoked potentials (SEPs and VEPs, respectively). SEPs, elicited by 1 mamp, 0.5 msec pulses delivered to the tibial nerve at the tibale, were recorded from the skull overlying the somatosensory projection area on days 28, 35, 42, and 49 postconception (pc). Analysis of the data for day 35 pc double pulse SEPs revealed significantly longer latencies for all peaks of the SEP in pups exposed to diesel exhaust. There were also differences indicating that the electrophysiological recoverability of the nervous system had been compromised in the diesel exhaust exposed group. On day 35 pc, the latencies of all VEP peaks occurring before 300 msec were greater in the exposed group. The differences, however, reached statistical significance only for the P2 peak of the response to the first of the paired stimuli. These data support the hypothesis that diesel exhaust influences the development of the nervous system. JF - Environment International AU - Laurie, R D AU - Boyes, W K AD - Health Effects Res.

AN - 15429490; 243769 AB - Eight food-deprived rates were trained to perform under a schedule that arranged milk reinforcement after every 10 (N=4) or 40 (N=4) lever preses. Baseline control performance for all rats was characterized by a brief pause in responding after milk delivery, followed by a rapid rate of responding that was maintained until the next milk delivery. Chlordimeform HCI (CDMF) produced dose-related decreases in response rat and increases in pause duration when 1.25-40 mg/kg bodyweight was given IP,10 min pre-session. Dosages estimated to produce a 50% decrease in overall responding were between 5 and 10 mg/kg for rats performing under either response requirement. Similar effects on performance were obtained when 5 mg/kg CDMF was given 10 and 50 min pre-session, and when 10 mg/kg was given 10, 50, and 120 min pre-session. The effect of 5 mg/kg CDMF (10 min pre-session) was not consistently modified by prior monoamine oxidase inhibition with pargyline HCI (20 or 50 mg/kg, 60 min pre-session). CDMF (10mg/kg) also decreased the rate at which rats (N=5) responded, and increased the rate of shock delivery, under a signaled shock avoidance paradigm. JF - NEUROBEHAV. TOXICOL. TERATOL.

AN - 15428894; 243462 AB - Polychlorinated biphenyls (PCBs) have been recognized as environmental contaminants since the mid-1960s. Until recently, however, little work has been done on identifying levels of PCBs in the indoor air. This paper describes a method for the analysis of PCBs utilizing low-volume indoor air sampling. The method uses polyurethane foam as a collector and has a limit of detection of similar to 0.01 mu g/m super(3). This study shows that indoor air, whether in commercial, industrial, or residential buildings, contains levels of PCBs at least 1 order of magnitude higher than outdoor levels. Defective fluorescent light ballasts are also shown to emit PCBs and to be an important source of indoor atmospheric contamination. JF - Environmental Science & Technology AU - MacLeod, KE AD - Anal.

AN - 15423899; 234520 AB - Adult male, inbred, disease-free cats of uniform age and size were exposed eight hours per day, seven days per week to a 1:18 dilution of diesel exhaust emissions. After one year of exposure, the animals were removed from the chambers for measurement of lung volumes, forced expiratory flow rates, dynamic compliance and resistance, diffusing capacity, and nitrogen washout. No important changes in pulmonary function were detected with the exception of a decrease in closing volume (P<0.05). The inability to detect decrements in pulmonary function may have been due to insufficient concentration of exhaust, insufficient exposure length, or to the use of a species resistant to diesel exhaust. To test these possibilities, the cats are being exposed for an additional year, and another species, hamsters, are being exposed for future testing at exhaust dilutions of 1:18 and 1:9.

It has low solubility in seawater (24 mu g/L), strongly adsorbs to sediment and particulate matter in water, has a half-life of 24 days in estuarine sediment in laboratory systems. Acute toxicity tests conducted at the Gulf Breeze Environmental Research Laboratory indicated that fenvalerate was extremely toxic to various aquatic organisms: mysid shrimp (Mysidopsis bahia ), pink shrimp (Penaeus duorarum ), four species of fish (Mugil cephalus, Menidia menidia, Opsanus beta , and Cyprinodon variegatus ), lobster (Homarus americanus ), sand shrimp (Crangon septemspinosa ).

The effect of pretreatment on the excretion of radioactivity and the distribution of eight lindane metabolites was examined. Even though the rate of lindane metabolism was unchanged by the beta -naphthoflavone pretreatment, results of the study indicated that all three pretreatments significantly altered lindane metabolism. The pretreatments differed from one another in that they selectively altered specific metabolic pathways.

AN - 15410095; 234774 AB - In the initiation/promotion assay in rat liver, partial hepatectomy is used to enhance initiation, and a choline-devoid diet as promoter. The induction of carcinogenesis is determined by the focal appearance of gamma glutamyl transpeptidase (GGT) positive hepatocytes. The authors adopted this assay to diesel exhaust emission by performing a 2/3 partial hepatectomy, and exposing the rats to either clean air or diesel exhaust emission. The rats were fed either a choline-devoid or a choline-supplemented diet for three or six months. The animals were sacrificed and liver sections stained for GGT were examined for the presence of foci of GGT(+) hepatocytes. The results indicate that diesel exhaust exposure does not result in a systemic dose of carcinogens sufficient to be detected in the liver foci assay.

AN - 15402709; 218260 AB - A series of experiments was conducted in which groups of mice were first exposed for various durations to diluted exhaust from light duty diesel engines and then briefly to an infectious aerosol generated by nebulizing cultures of a bacterial pathogen (Streptococcus ). Typically, postinfection mortality was signigicantly greater in groups exposed to exhaust than in their corresponding control groups exposed to purified air only. Data of recent diesel and of past diesel- and catalyst-treated gasoline engine exhaust experiments suggest a somewhat grreater excess mortality from (enhanced susceptibility to) bacterial infection in mice exposed to diesel exhaust than in those exposed to catalytic gasoline exhaust. Limited data on acute tests of NO sub(2) and acrolein vapor alone suggest that the infectivity-enhancing effect of diesel exhaust could be accounted for in large part by these components. Exposures to diesel exhaust, NO sub(2), or acrolein did not enhance the mortality response to a viral pathogen (A/PR8-34).

AN - 15400221; 218303 AB - An intensive survey of water quality parameters was conducted on Lake Michigan during 1976 and 1977. A dynamic phytoplankton simulation model (MICH1) was developed to investigate the observed field data and to use in forecasting lake responses to various phosphorus loading scenarios. The 1977 data indicated that the southern basin of Lake Michigan lost up to 3 mu g P/L compared to concentrations observed in 1976. In an attempt to simulate this rapid depletion of phosphorus, MICHI1 required an implicit representation of suspected effects of an extensive ice cover observed during the winter of 1976-77. This included increasing the net apparent settling rate eight fold during ice cover. A total phosphorus model (TPM) was used in conjunction with MICH1; for forecasting. These forecasts indicate a steady-state total phosphorus concentration of 7 mu g P/L, given a target load recommended by the 1978 Water Quality Agreement. The projected time to obtain 95% of steady-state response to a load change was 7-14 years. JF - Journal of Great Lakes Research AU - Rodgers, P AU - Salisbury, D AD - EPA Large Lakes Res.

AN - 15398191; 213639 AB - The proposed conversion from gasoline powered automobiles to diesel powered vehicles has prompted the Environmental Protection Agency to evaluate the potential health effects associated with exposure to diesel emissions. At present, there is no direct epidemiological link between this exposure and human health. Therefore, a research program was constructed to compare the health effects associated with diesel emissions with those from other emission sources for which epidemiological information was available. The emission sources chosen chosen were cigarette smoke, roofing tar, and coke oven. An additional comparative emission source which was evaluated, was a gasoline catalyst engie. Respirable particles from a variety of combustion sources have the potential of being carcinogenic and mutagenic. The objective of these studies was to determine the relative biological activity of the organic material adsorbed on these particles in both in vitro mutagenesis and in vitro and in vivo carcinogenesis bioassays.

AN - 15395407; 215420 AB - Data in twelve power plant and smelter plumes reported by eight different organizations have been reviewed in an attempt to establish the existence of recognizable patterns concerning the extent and rates of sulfate formation. The data reviewed here were collected in Australia, Canada and the U.S., during warm as well as cold seasons, and during day and night. The primary variables examined and compared are S sub(p)/S sub(T), the particulate fraction of excess sulfur sampled in the plume, and the corresponding plume age. The variation of the extent of sulfate formation (S sub(p)/S sub(T)) is also examined in terms of plume exposure to solar radiation dose during transport. In spite of wide geographical, seasonal, background and source variations, a distinct difference is observed in day and night sulfate formation. During the daytime, there exists a substantial variability in sulfate formation rates (typically 0-5%h super(-1)) and extent (typically up to 25%) for any given physical plume age. This variability is significantly less for plumes with similar exposure to sunlight dose, showing that environmental factors linked to solar radiation strongly influence the rate and extent of sulfate formation in point-source plumes.

AN - 15395398; 213718 AB - The intraperitoneal injection of 5-hydroxytryptamine (5-HT) in unrestrained and unanesthetized mice held at 22 degree C causes a hypothermia which is maximal after approximately 15 min. When mice injected with 5-HT were held in a controlled environment of 22 degree C and 50% relative humidity and exposed to microwaves (2450 MHz, cw) at 1 mW/cm super(2) for 15 min, significant increases were observed in the body temperature of these mice compared to 5-HT-treated sham-irradiated mice. The magnitude of the response was related to power density (10 > 5 > 1 mW/cm super(2))/. Saline-injected mice exposed for 15 min at 10 mW/cm super(2) (specific absorption rate = 7.2 mW/g) showed no significant increase in body temperature compared to saline-injected sham-irradiated mice.

AN - 15391708; 214155 AB - Female Swiss mice were exposed 8 h/day to diesel exhaust for 1, 3, and 7 weeks. Urine was collected overnight for 4 days prior to sacrifice while the mice continued to be exposed for eight hours during the day. The presence of mutagens was determined by the Ames Salmonella test. One hour prior to sacrifice each mouse received 1 mg/kg colcemide. After sacrifice, the marrow from each femur was obtained. The marrow from one femur was used to prepare slides for metaphase analysis and the other for micronuclei assay. Other mice received IP 50 mg/kg cyclophosphamide 24 h prior to sacrifice or 1 mu mole/kg benzo(a)pyrene in each of four daily doses prior to sacrifice and served as positive controls. The Ames Salmonella assay of the unconcentrated urine after 1, 3, and 7 weeks and concentrated urine after 7 weeks exposure to diesel exhaust did not significantly vary from clean air controls. In the micronucleus test, and metaphase analysis, cyclophosphamide produced a strong positive response and the 7 week diesel exposure was not different from clean air controls.

The animals were kept in specially constructed inhalation chambers and exposed to clean air or diesel exhaust for eight hours daily. The animals were sacrificed and slides prepared to study the mutagenic effects of diesel exhaust by four in vivo short term mammalian bioassays. Sperm morphology bioassay revealed a 2.67-fold increase in sperm abnormalities in the animals exposed to diesel exhaust as compared to those exposed to fresh air. Micronucleus bioassay revealed a 50% increase in the number of micronuclei in polychromatic erythrocytes obtained from animals exposed to diesel exhaust. However, no increase in sister chromatid exchange or chromosomal abnormalities was observed in bone marrow cells of animals treated with diesel exhaust. During these studies a decrease in mitotic index was observed in animals treated with diesel exhaust.

AN - 15388184; 213159 AB - It is the major intent of this report to examine the animal inhalation facilities at the EPA Health Effects Research Laboratory in Cincinnati, Ohio, associated with the exposure to the exhaust of diesel-powered equipment. The facility serves as a center for toxicologic evaluation, in relevant animal models, of potentially hazardous environmental pollutants from diesel engine exhaust. Briefly, the entire engine exhaust is mixed with filtered and conditioned air in a dilution tube. That diluted exhaust enters a large volume mixing chamber and a portion passes through dynamic flow irradiation chambers (to simulate sunlight) and is then conducted to animal exposure chambers. The system provides nonirradiated exhaust in the same concentration (directly from the mixing chamber) and also filtered, conditioned ambient air for control animal exposure. The major physical components of the diesel emission system include: air purifiers, animal exposure chambers, engine-dynamometers, irradiation chambers, monitoring instrumentation and data acquisition systems.

AN - 15388110; 213257 AB - The biochemical response to controlled exposures of nitrogen dioxide (NO sub(2)) was studied in 19 human subjects exposed to 0.2 ppm NO sub(2) for 2 hr and compared to 15 control subjects exposed to filtered air for 2 hr. Seven biochemical blood parameters, including glutathione, red blood cell glutathione reductase, 2,3-diphosphoglycerate, methemoglobin, vitamin E, complement C sub(3), and IgA were measured prior to exposure, immediately after exposure, and 22 hr following exposure. The only variable that showed significant change due to NO sub(2) exposure was glutathione. Glutathione is known to protect the erythrocyte from oxidative stress. The increase in glutathione observed upon exposure to NO sub(2) may be a protective reaction of the erythrocyte to meet the oxidative stress. JF - ARCHIVES ENVIRON. HEALTH.

AN - 15385930; 215054 AB - Due to the expected increase in the percentage of diesel vehicles in the United States, the Environmental Protection Agency must evaluate the health effects associated with exposure to diesel emissions. Respirable particles from a variety of combustion sources have the potential of being carcinogenic and mutagenic. The objective of these studies was to determine the relative biological activity of the organic material adsorbed on these particles in in vitro mutagenesis bioassays. The organic extracts from the following series of emission sources were bioassayed in the Salmonella assay for mutagenic activity: (1) a light-duty Oldsmobile diesel 350 engine; (2) a heavy-duty Caterpillar diesel engine; (3) a light-duty Nissan engine; (4) a Volkswagen Rabbit diesel engine; (5) cigarette smoke; (6) roofing tar; (7) coke oven; and (8) a gasoline catalyst Mustang. This paper provides a comparison of these sources within the Salmonella bioassay and also demonstrates how bacterial systems can be used as a quality assurance measure in in vivo testing.

AN - 15374616; 197492 AB - The disposition of super(14)C-labeled methylparathion, parathion, and p-nitrophenol applied as a foliar spray was examined in the Terrestrial Microcosm Chamber (TMC) and compared to a reference compound, dieldrin. The impact of soil type (synthetic vs. natural) and airflow rates through the chamber on methylparathion disposition was evaluated. The TMC contained either a synthetic soil medium or Willamette sandy loam soil plus agricultural crops, numerous invertebrates, and a gravid gray-tailed vole (Microtus canicaudus ). Dieldrin was accumulated to a lesser extent than any of the organophosphates in the synthetic soil. Concentrations of methylparathion in the upper layer of Willamette sandy loam soil were consistently lower than those observed with the synthetic medium. Increased airflows altered methylparathion distribution primarily through increased export from the TMC. Although recovery of dieldrin was lower than with equivalent applications of organophosphates, a significantly greater concentration was detected in the vole. Only dieldrin appeared to affect vole survival. JF - Journal of Agricultural and Food Chemistry AU - Gile, J D AU - Gillett, J W AD - Terrestrial Div., Corvallis Environ. Res.

AN - 15371606; 198213 AB - The persistence and disappearance (washoff or dryfall) of methoxychlor (2,2-bis(p-methozyphenyl)-1,1,1-trichloroethane) from mature soybean (Glycine max (L.) Merrill) foliage was investigated in a small field plot study under natural rainfall conditions in 1977 and 1978. Residue analyses were conducted using whole plant samples. The amount of dryfall was significantly greater in plots entered by workers than in those where entry was avoided. Statistical analyses indicated that within-sample variation for mechanical chopping of plant samples was significantly smaller at the 5% level than for a hand chopping method. Results from this study will be useful in defining research objectives for the development of algorithms to describe the behavior of foliar-applied compounds. Such algorithms are necessary for estimating runoff losses of insecticides to water bodies. JF - J. ENVIRON. SCI. HEALTH.

AN - 15369938; 197646 AB - Before development of an emission standard for vinyl chloride, the Environmental Protection Agency (EPA) conducted three programs to measure vinyl chloride (VC) concentrations in air around plants which either manufacture VC or use it. A brief monitoring survey conducted by EPA Regional Offices found VC in ambient air around poly(vinyl chloride) (PVC) production plants. As a consequence of this survey, a second monitoring program was established to measure VC in the air around VC and PVC production plants. This program found some relatively high concentrations of VC in ambient air around the plants. This program found maximum 24-hr average concentrations ranging from 0.32 to 10.6 parts of VC per million parts of air. The program also found an apparent relationship between certain emission excursions and ambient VC concentrations. A third monitoring program was established to measure VC around PVC fabrication plants. This monitoring program found much less VC around PVC fabrication plants than around VC and PVC production plants.

AN - 15369398; 197721 AB - In regulation of exposures to hazardous environmental agents, epidemiologic evidence is especially important in defining human risk estimates. The process of developing appropriate regulations is complex, however, and depends on many considerations beyond those established to a high degree of scientific certainty. Thus the needs of regulatory agencies are involved in the way epidemiologic data are developed and presented. To coordinate and review common problems associated with preventive and regulatory activities among the federal agencies concerned with regulation, and Interagency Regulatory Liaison Group (IRLG) was established in 1977. Because of difficulties encountered by these agencies or Congressional committees in evaluating epidemiologic evidence, a subcommittee of the IRLG has developed in draft form guidelines for human population studies to be used in public health decision-making. Although these guidelines have attracted much controversy, their aim is to present criteria for design and documentation of epidemiologic studies, without interfering with the initiative of investigators.

AN - 15366523; 198116 AB - This study was designed to reveal patterns of response of major United States crops to sulfuric acid rain. Potted plants were grown in field chambers and exposed to simulated sulfuric acid rain (pH 3.0, 3.5 or 4.0) or to a control rain (pH 5.6). At harvest, the weights of the marketable portion, total aboveground portion and roots were determined for 28 crops. Of these, marketable yield production was inhibited for 5 crops (radish, beet, carrot, mustard greens, broccoli), stimulated for 6 crops (tomato, green pepper, strawberry, alfalfa, orchardgrass, timothy), and ambiguously affected for 1 crop (potato). In addition, stem and leaf production of sweet corn was stimulated. Visible injury of tomatoes might have decreased their marketability. No statistically significant effects on yield were observed for the other 15 crops. The results suggest that the likelihood of yield being affected by acid rain depends on the part of the plant utilized, as well as on species. Effects on the aboveground portion of crops and on roots are also presented. JF - ENVIRON. & EXPER. BOTANY.

The initial evaluation of this test system was accomplished using cadmium chloride, chromium chloride, cobalt chloride, mercuric chloride, nickelous chloride, sodium arsenite, sodium selenite, and ammonium vanadate. The relative toxicity of the compounds was as follows: Cd > V = As > Se > Hg > Cr = Co > Ni. Since several of the compounds with very similar EC sub(50)s had significantly different dose response slopes, an additional parameter, lowest effective concentration tested (LECT) was employed to assess the relative toxicity. The LECT was determined using the Williams test and the relative toxicity of the compounds was found to be Cd = Se > V > As = Hg > Co > Cr = Ni. JF - IN VITRO, J. TISSUE CULT. ASSOC.

AN - 15351917; 173160 AB - The effects of ozone (O sub(3)) on cell-mediated immunity were studied in 16 human subjects exposed to 1176 mu g/m super(3) O sub(3) (0.6 ppm) for 2 hr in an environmentally controlled exposure chamber. Venous blood samples were taken before and immediately after controlled air and O sub(3) exposures, as well as at 72 hr, 2 and 4 weeks, and at one random time at least 1 month after treatment. No statistically significant changes were observed in the number of T lymphocytes that form spontaneous rosettes with sheep erythrocytes. The response of T lymphocytes to PHA was significantly reduced in samples taken at 2 and 4 weeks following O sub(3) exposure. Normal response to PHA was observed at 2 months post-O sub(3) exposure. No statistically significant changes in lymphocyte responses to Con A, PWM, or Candida) were seen. These results show that one 2 hr exposure of humans to 0.6 ppm O sub(3) may lead to a transient suppression of the PHA-stimulated blastogenic transformation of peripheral blood lymphocytes. The data indicate that the blastogenic response to PHA of human lymphocytes is exquisitely sensitive to O sub(3) exposure and could serve as a bioassay for evaluating subtle changes in cellular immunity induced by O sub(3) and possible other pollutants.

AN - 15346758; 166192 AB - For a bimodal size distribution of ambient aerosol the upper particle size limit of the fine aerosol fraction can be chosen in such a way that the extinction coefficient for light scattering and absorption is directly proportional to the fine mass concentration, regardless of the magnitude of the coarse mass concentration. With the size parameters of the modes taken to be the "grand average continental" values of Whitby, the upper size limit is 3.4 mu m (aerodynamic diameter).

AN - 15346261; 166317 AB - Extensive research has determined that adipic acid, when used as an additive to a limestone flue gas desulfurizaiton (FGD) system, will improve the performance of the system. Both SO sub(2) removal and limestone utilization can be greatly increased by the buffering effect of adipic acid. Successful testing in laboratory, bench, pilot, prototype, and full scale systems has demonstrated the benefits of this technology for new and retrofit applications. Although adipic acid does degrade in the scrubber, no significant operating problems or environmental impacts have been identified. Economic estimates have shown the adipic acid enhanced limestone FGD system to be economically attractive when compared to conventional FGD systems. In addition, further research is underway to decrease the cost of using additives in FGD systems. JF - J. AIR POLLUT. CONTR. ASSOC.

I. Slow Cortical Potentials. AN - 15340782; 164313 AB - The effects of body Pb burden on slow cortical potentials were studied in 63 children aged 13-75 months. Slow wave (SW) voltage during sensory conditioning varied as a linear function of blood lead (PbB) level. The slope of this function, moreover, changed systematically with age. For children under 5 years of age, SW voltage tended to be positive at low PbBs and to be negative above 30 mu g/dl. For children over 5 years of age, SW voltage tended to be negative at low PbBs and to be less negative (or positive) above 30 mu g/dl.

AN - 15339932; 167501 AB - Diethyl was determined in water and sediment by high performance liquid chromatography (HPLC) and in water by gas-liquid chromatography with electron capture detection (GLC-EDC). Water samples were extracted with hexane, using a high-speed homogenizer-ultrasonic apparatus and a test tube mixer. Sediments were Soxhlet-extracted using acetonitrile. For HPLC, diethyl phtalate was determined in normal phase mode using a Zorbax-CN column, a 2% isopropanol-hexane solvent system, and a UV variable wavelength detector. For GLC-ECD, a 3% SE-30 Gas-Chrom Q column with a super(63)Ni electron capture detection system was used. Recoveries from fortified samples ranged from 93.9 to 98.0% for water at 0.01-0.50 ppm, and from 90.0 to 93.6% for sediment at 0.2-2.0 ppm.

Fetal and maternal toxicity was observed in both species. In the mouse, maternal toxicity was observed in both species. In the mouse, maternal toxicity was evident at the lowest dose, while teratogenic response was confined to cleft palate at 400 and 600 mg/kg/day. The effective maternal toxic dose in the rat was 40 mg/kg/day. In this species, incidence of irregular palatine rugae was significantly dose-related. The results suggest an "apparent no effect level" for this anomaly below 30 mg/kg/day. JF - Drug and Chemical Toxicology AU - Rogers, E H AU - Chernoff, N AU - Kavlock, R J AD - Exp. Biol.

II. EEG Spectra. AN - 15339740; 164338 AB - This sutdy explored the effect of age and PbB upon EEG power spectraand various measures of hemispheric laterality in children, ages 13-75 months. The delta - and theta -band amplitude decreased with age. When only bilaterally synchronized EEG between P3 and P4 was considered the amplitude of P3 was estimated as greater than P4 in all frequency bands and for all ages. Previous reports have not shown lateral EEG dominance in children below 75 months. When lateral dominance measures consider only the ralationship between synchronized EEG at P3 and P4, bilateral communality in the delta band increased with age. Increased PbB generally produced an increase in the relative amplitude of synchronized EEG between P3 and P4 in all frequency bands. This was true for PbB levels well below 15 mu g/dl, among the lowest level PbB effects previously reported. No clinical or behavioral effects of PbB values have been reported below 15 mu g/dl.

AN - 15337443; 165697 AB - During the summer of 1979, coefficients for light extinction in the atmosphere were calculated from measurements made wtih a telephotometer placed 251 m from a black target in Research Triangle Park, North Carolina. The results are well crrelated (r = 0.92-0.96) with integrating nepnelometer measurements of scattering coeffiecients and are highly correlated ( r= 0.99) with daily arithmetic averages of sums of scattering and absorption coefficients. The average sume of scattering and absorption coefficients accounts for about 90% of the average telephotometrically measured extinction coefficient. Scattering by particles and scattering by air contribute 75 and 7% of the measured extinction coefficient; absorption by particles and absorption by nitrogen dioxide contribute 7 and 2% respectively. From measurements of the aerosol mass and elemental composition, it is inferred that sulfate and its cations account for at least 54% of the mass of particles smaller than 2.5 mu m in dia.

AN - 15335703; 154333 AB - Theories of light extinction and contrast reduction by atmospheric aerosol are reviewed. Errors inherent to telephotometry are analyzed. Significant errors may result from unknown target luminance, stray light within the telephotometer, and uneven illumination due to clouds. Measurements by a telephotometer of the extinction coefficient of the relatively turbid atmosphere of the eastern U.S.A. are described. Because of current levels of extinction, it is feasible to apply a dual target technique developed by Ruehle, which corrects for the targets' imperfect blackness and stray light imperfections in the telephotometer optics. The results compare favorably (r = 0.97, slope = 1.08) to independent measures of scattering and absorption coefficients when the most obvious cases of uneven illumination due to clouds are excluded. The agreement of these two independent measurement methods for extinction coefficient lends credence to them both. However, the difficulty of automating cloud detection for the telephotometer remains a formidable practical problem. JF - Atmospheric Environment AU - Ellestad, T G AU - Speer, R E AD - Environ. Sci.

AN - 15332091; 154246 AB - Many Class I areas have unique vistas which require an observer to look over complex terrain containing basins, valleys and canyons. These topographic features tend to form pollution "basins" and "corridors" that trap and funnel air pollutants under certain meteorological conditions. For example, on numerous days, layers of haze in the San Juan River Basin obscure various vista elements including the Chuska Mountains as viewed from Mesa Verde National Park, CO. Measurements by an integrating nephelometer and a conventional teleradiometer at one location in Mesa Verde do not quantify the inhomogeneities. In this paper, data from these instruments are compared to data derived from scanning teleradiometer measurements of photographic slide images. The slides, surrogates of the real three-dimensional scene, were projected and scanned to determine relative sky and vista radiance at 40 points within a vertical slice of the vista. Comparison of the corresponding visual range data sets for each instrument for September and December 1979 demonstrates the utility of the scanning teleradiometer.

AN - 15327124; 157127 AB - Benzene exposures may affect human health in three ways: (1) increasing the incidence and severity of acute illness, (2) increasing the incidence and severity of chronic illness, and (3) increasing mortality rates. These adverse health effects result in tangible and intangible losses. Examples of tangible losses are time away from work, lower productivity during working hours, and use of medical resources. Intangible costs are the anxiety, pain and fear in individuals and their family and friends. These costs are seldom considered in an economic evaluation of adverse health effects. Information about the adverse health effects associated with benzene exposure is very limited as is evident from the section characterizing risk.

AN - 15323635; 141245 AB - Although RCRA is the principal U.S. law governing hazardous wastes. The Toxic Substances Control Act (TSCA) also contains limited authority to regulate the export of chemicals and chemical wastes which are regulated domestically under TSCA if EPA finds the export will present an unreasonable risk of injury to the health or the environment within the United States. It is under TSCA that wastes contaminated with polychlorinated biphenyls (PCB's) or TCDD (dioxin) are controlled for export. Under present regulations, PCB's may not be exported for disposal unless the U.S. and the other country have entered into a Memorandum of Understanding which establishes mutually agreed upon criteria for their storage, transportation and disposal. At the present time there are no such Memoranda between the U.S. and any other nation, and exports and imports of PCB wastes are banned. For wastes containing TCDD, EPA requires a 60-day advance notice of shipment, and exports are dealt with on a case-by-case basis. JF - EPA Journal AU - Greider, W AD - EPA's Off. Int.

AN - 15319458; 137516 AB - Strains of E. coli recently isolated from human feces were examined for the frequency with which they accept an R factor (R1) from a derepressed fi super(+) strain of E. coli) K-12 and transfer it to fecal and laboratory strains. The majority of fecal E. coli isolates accepted the R factor at lower frequencies than K-12 F super(-). The frequencies with which certain fecal recipients received the R-plasmid were increased when its R super(+) transconjugant was either cured of the R1-plasmid and remated with the fi )strain or backcrossed into the parental strain. The former suggests the loss of an imcompatibility plasmid, and the latter suggests the modification of the R1-plasmid deoxyribonucleic acid (DNA). Passage of the R1-plasmid to strains of salmonellae reached mating frequencies of 10 super(-1) per donor cell when the recipient was a Salmonella typhi previously cured of its resident R-plasmid. However, two recently isolated strains of Salmonella accepted the R1-plasmid from E. coli K-12 R super(+) or the R super(+) E. coli) transconjugants at frequencies of 5x10 super(-7) or less.

III. Alterations of Behavioral Ontogeny. AN - 15316903; 125220 AB - In the hamster, prenatal exposure to endrin at 1.5 mg/kg/day on days 5-14 of gestation produced a persistent elevation in the locomotor activity. Offspring of treated hamsters ambulated 75% more than controls in the open field at 15 days and 45% more at 20 days of age. Long term observations of locomotor activity in the figure-8 mazes indicated that a significant elevation of this behavior was still present at 125 days of age. Non-locomotor behaviors of the offspring (including sexual, rearing and running wheel behaviors) were unaffected. In the second experiment, rats exposed perinatally to endrin at 0.15 or 0.30 mg/kg/day were 30% more active than controls prior to weaning, but not as adults. The similarity of the behavioral changes noted in the young of both species is suggestive of simular alterations of central nervous system function even though endrin produces gross morphological defects only in the hamster.

Organic solvents were more efficient than physiological fluids in removing mutagens from diesel particles, with dichloromethane extracts having the greatest mutagenic activity of the solvents examined. Serum and lung cytosol were more effective than acellular lung lavage fluid in releasing mutagenic activity from diesel particles. The mutagenic activity of diesel particle organics preextracted with dichloromethane is greatly reduced upon the addition of serum and lung cytosol to organics.

AN - 15294028; 122752 AB - Flour and biscuit samples from a school lunch program were analyzed for ethylene dibromide (EDB). Flour samples were extracted with hexane at room temperature with maximum extraction of EDB in 4 days. Biscuits were extracted by steam distillation with hexane; optimum recoveries were obtained by a triple extraction of the sample. Recoveries of EDB from flour and biscuits ranged from 85 to 103% as determined by gas-liquid chromatography on a 15% OV-17 column and a super(63)Ni electron capture detector. Random samples were confirmed by gas chromatography-mass spectrometry. From <8 ppb to 4 ppm EDB were determined in flour and <0.5 ppb to 260 ppb in biscuits. Possible sources for the higher values are discussed. JF - Journal of the Association of Official Analytical Chemists AU - Rains, D M AD - U.S. EPA, Chem. & Biol. Invest.

AN - 15293838; 122634 AB - Vitamin C-deficient and normal guinea pigs were exposed to various concentrations of NO sub(2) or air, and lavage fluid was obtained and analyzed for protein and lipid content. Exposure of normal animals to 752, 1880, 5640, or 9400 mu g NO sub(2)/m super(3) (0.4, 1.0, 3.0, or 5.0 ppm) for 72 hr did not alter the protein or lipid content of lung lavage fluid. However, exposure of vitamin C-deficient animals to the same concentrations of NO sub(2) caused marked increases in lavage proteins and lipids at all but the 752 mu g/m super(3) (0.4 ppm) level. At 9400 mu g NO sub(2)/m super(3) (5.0 ppm), 50% of the exposed vitamin C-deficient animals died, and pathologic study of the lungs showed proteinaceous edema fluid in the alveoli.

AN - 15293729; 123057 AB - Venturi scrubbers are highly efficient in removing submicron dust particles from gas streams. Basically, the gas stream accelerates in the converging section of the venturi to maximum velocity in the throat, where it is sprayed by a scrubbing liquor. The faster velocity of the gas stream atomizes the liquor, and promotes collisions between the particles and the droplets. Agglomeration in the diverging section produces droplets, with entrapped particles, of a size easily removed by mechanical means.

Palladium (II and IV) and gold (III) were the strongest inhibitors of RNase activity. Other strong inhibitors, in decreasing order of effect, were: sodium dedecyl sulfate, silver (I), EDTA, mercury (II), copper (II), thiram (fungicide), platinum (IV), malathion (pesticide), lead (II), and beryllium (II). Intermediate effects were found with other inorganic cations, many anions, and some other chemicals. A number of compounds of different chemical types caused no measurable effect. None of the chemicals tested caused a measurable activation of this enzyme. JF - Environmental Research AU - Christensen, G M AU - Olson, D L AD - US EPA, Environ. Res.

AN - 15288374; 114858 AB - Duckweed (L. perpusilla ), inhabiting a heavy coal ash, secondary retaining basin from a coal-fired power plant, was the most abundant macrophyte sampled during the summer-fall period of 1979. Lemna in the basin accumulated the most abundant heavy and soft metals (Cd, Cu, Fe, Mn, Zn, Cr, Pb, Ni) affiliated with heavy ash to a greater extent than found in water or coal ash sediment. After a14-day holding period under laboratory conditions of low metal influence, some duckweed metal concentrations declined to levels similar to those found in the ash basin sediments, while other tissue concentrations remained higher. During the 10-day laboratory exposure bioassay after the depuration period, high duckweed mortality was evident within 2 to 10 days at concentrations of 10x and higher. The capacity of duckweed to accumulate potentially toxic heavy metals in coal-ash-retaining systems may have an important role upon the displacement of these elements on a seasonal basis. Aquatic elemental releases of duckweed may be minimal during the growing season due to the bioconcentration capability but can be maximal in the fall during the process of natural mortality and the resulting depuration process into the receiving drainage system.

As a consequence of these studies, nationwide trends in concentrations of the benzene soluble fraction (BSO) and BaP were determined for the 1967-70 period from ambient suspended particulate samples collected by the National Air Surveillance Network (NASN). super(3) The 1967-70 trends for BaP were extended through 1972 at 33 urban sites. Recently, BaP data for 1973-77 have become available at most of the urban sites form the earlier study, at some additional urban sites, and at three rural or background sites.

AN - 15280731; 116750 AB - In 1979 the Environmental Protection Agency (EPA), the Department of Commerce (DOC), the Department of Housing and Urban Development (HUD), and the Department of Transportation (DOT) jointly awarded demonstration grants to eight urban areas to develop and test ways to coordinate economic development and air quality improvement. In the approximately two years since the first grant award, a great deal has been learned about how the needs of communities and industries might best be addressed in working toward local economic and air quality goals. The economic development and air quality problems facing the areas receiving AQTAD grants have been more clearly defined. Improved working relationships have developed among state and local agencies. Changes in the direction and emphasis of some of the activities of the grantees have also occurred. This paper presents interim results of the grants program, focusing on activities that have progressed far enough so that some evaluation of their potential success is possible. Where an urban area has made mid-course changes in grant acticities, a preliminary assessment is made of the reasons for the change. JF - J. AIR POLLUT. CONTR. ASSOC.

The Agency provides expertise to the US Department of State and other Federal agencies for negotiations on a number of salt-water issues related to ocean dumping, vessel pollution, the law of the sea, and Antarctic resources. The Agency's largest involvement is in the area of ocean dumping. As lead agency in the Federal Government for implementing the 1972 London Dumping Convention, EPA chairs United States delegations to negotiations held pursuant to the Convention, and provides most of the scientific and policy support for such deliberations.

The method does not require the use of a computer and eliminates the usual trial and error calculations. An infinite mixing height is assumed. It involves a linear or quadratic solution of the gaussian plume diffusion as a function of the effective stack height and a linear approximation of the Briggs plume rise equation. The linear approximation of the former gives results that are within 5% of the gaussian plume results for stability criteria A, B, and C. For stability criteria D, the difference can be as great as 80%. If a quadratic estimation is used, the differences are less than 3% for stability criteria A, B, and C, and are within 18% for stability criteria D. A linear approximation is used for the Briggs plume rise equation. JF - J. AIR POLLUT. CONTR. ASSOC. AU - Baasel, W D AD - Indust. Environ. Res.

The physiological stress indices, scope for growth, oxygen to nitrogen ratio and growth efficiency were calculated. There was a significant decline in the performance and physiological condition of mussels from south to north along Narragansett Bay, and this was associated with increasing pollution.

The ambient gases considered in the chemistry were SO sub(2), NO, NO sub(2), HNO sub(3), O sub(3) and CO sub(2). Raindrops initially at a pH of 5.5 absorbed these gases, and as they fell through a polluted zone, produced SO sub(4) super(2)-a)nd NO sub(3)u- by the oxidation of dissolved SO sub(2) by O sub(3) and the dissociation of HNO sub(3), which reduced the pH. For the chemical mechanism and the below-cloud washout rain events considered, it was observed that: absorption of gaseous HNO sub(3) controlled the acidification in the initial stages of a rain event, and inhibited the production of So sub(4) super(2)- )NO and NO sub(2) played no direct role in the acidification or formation of NO sub(3)u- or SO sub(4) super(2)- )pre-acidified raindrops (pH of 4) were further acidified only by absorbing HNO sub(3).

Linear correlation coefficients of 0.99,0.96, and 0.96 were observed for the three individual sets of measurements, and a linear correlation coefficient of 0.93 was observed for all measurements. Light attenuation-mass measurements showed similar results when the plant was operating at full and half loads. Particle size measurements were made on four different occasions during the study with similar results. The work indicates that an empirically calibrated light transmissometer has the potential for monitoring the mass concentration of particulate emisiions from coal-fired power plants, although the stability of such correlations and the calibration frequencies necessary to maintain specific accuracies need to be better defined.

Risk assessment for the use of materials chosen for RPAR include estimates of worker exposure during various agricultural operations. Observations during earlier field studies in the Columbia Basin Irrigation Project, led us to believe that there was considerable use of captan as a fungicide for seed potatoes. During the spring of 1979 we undertook a study of the potential for exposure to captan of workers involved with various aspects of potato planting.

Emission rates were calculated for SO sub(2), total sulfate, and particulate matter expressed as g emitted/gal of oil fired. Sulfate emissions amounted to approximately equals 13.4% of the SO sub(x) from the sources. The sulfate emission factor was found to be related to the accumulation of V-containing ash in the boilers resulting in the catalytic oxidation of SO sub(2). Nearly 35,000 boilers of these types are operational in New York City, especially in the winter, to provide heat and hot water. Their elevated sulfate emission rates could play a dominant role in the occurrence of elevated sulfate levels near the metropolitan area during winter episodes. JF - J. AIR POLLUT. CONTR. ASSOC.

Persistence of residues from both formulations spilled as concentrates and as simulated drum rinses were followed for up to 45 months. Spillage of encapsulated formulation resulted in the formulation of a solid cake-like deposit on the soil surface, which could be a particularly attractive hazard to small children. At 45 months, soil residues had decreased by 64% for emulsifiable concentrate spills, and 68% for the soil beneath the microencapsulated cake. Residue in the cake itself only decreased by 31%. Soil residue levels from simulated drum rinses were essentially innocuous by 45 months for the emulsifiable concentrate and by one year for the microencapsulated material.

The method provides estimates of the expectation of premature death and the resultant life shortening. Applications to occupational exposure situations are used to demonstrate the technique. Doses ranging from 0.2 to 5.0 rem/yr and over age spans from 10 yr to working lifetimes are investigated. A technique for comparing radiation related mortality with nonradiation related risk of death from on-the-job accidents is introduced. Results show that workers receiving whole body doses equal 5 rem/yr for sustained periods of time incur significant risk of premature death from radiation induced cancer. The risk is estimated, in some cases, to be as high as, or higher than, the average risk of accidental death in high risk industries, depending upon factors such as length of exposure, age at time of exposure, and the radiation risk model used.

The extraction of the compounds from urine is often incomplete and inconsistent. Several different approaches to the problem are currently being investigated In this work, the ion pair is extracted into dichloromethane which contains the alkylating agent, pentafluorobenzyl bromide. Since the non-polar solvent possesses poor solvating ability, it renders the alkyl phosphate highly reactive toward nucleophilic displacement. The resulting pentafluorobenzyl (PFB) ester derivative is thermally stable and highly responsive under conditions of gas chromatographic analysis using a flame photometric detector or nitrogen-phosphorus detector.

However, this film was found to liberate high concentrations of contaminants such as fluorocarbons, solvents, antioxidants, and manufacturing residues. These contaminants could interfere with both hydrocarbon analyses and smog-chamber reactivity studies. Heat treatment of FEP plastic film at 190 degree C for 24 h minimized film outgassing but did not eliminate it. Less outgassing occurred with 2-mil film than with 5-mil film. However, bags prepared from 2-mil film were more fragile than those prepared from 5-mil film. JF - ENVIRON. SCI. & TECH.

The U.S. EPA's RAM (Urban) model was chosen to estimate 24-hour average sulfur dioxide concentrations in the Cleveland, Ohio area. Point and area source emissions, along with a background concentration were included in the modeling effort. Projections from the model made at the ambient air stations were compared to measured sulfur dioxide concentrations. A total of 3020 comparisons were performed at 33 monitoring sites. An analysis of the results illustrates that, on a daily basis, the predictions of the model did not reflect actual air quality. The correlation coefficients of the 24-hour comparisons at the monitoring sites varied from a low of -0.121 to a high of 0.541. When the highest and second highest modeled concentrations were evaluated with respect to the highest and second highest measured concentrations, over a period of a year, a more favorable comparison was observed.

The two chemical treatments tested were reduction and hydrolysis. Both reactions should result in the elimination of the possibility of cyclic reduction-oxidation with resultant generation of super-oxide radicals, which has been proposed as the primary event responsible for the pulmonary fibrosis caused by paraquat. This pulmonary fibrosis can occur with oral or intra-venous administration or local instillation of paraquat.

Elemental and microscopical analysis of size segregated, ambient particulate and suspended soil samples from the rural southwest indicate that the particles are earth crust material. The composition of the soil related materials changes with changing particle size. Smaller particles tend to vary more in their elemental makeup than corresponding large particles. Numerous thin mineral plates with diameters of several micrometers are aerodynamically sized in the smallest sample size range (<0.5 mu m). Since silicon accounts for one-quarter to one-half the total mass in the fine particle size range, it may be a significant causal factor in regional visibility degradation.

The available evidence on the contribution of natural organics in photochemical pollution is conflicting. Emission measurements suggest that natural organics are emitted in amounts comparable to or even exceeding anthropogenic organics. The contrasting data are aerometric, showing natural sources to be minor in the organic loadings of urban and rural atmospheres. In a position based on the aerometric data in combination with reactivity data, natural organics are judged to contribute negligibly to urban ozone; their contribution to rural O sub(3) is less certain, probably not major.

Four orthogonal factors representing O sub(3) formation potentials were derived using the statistical package SPSS; these factors accounted for over two-thirds of the variations in 1978 summer O sub(3) levels at 21 urban-oriented stations. The analysis confirmed that O sub(3) variations are similar among stations within defined geographical areas; this confirmation supports the widely held theory that ambient O sub(3) formations are regionwide. The analysis suggested that trends analysis for determining general progress in improving O sub(3) air quality should be based on aggregate statistics from clusters of monitors rather than from a single monitoring station within areas associated with the derived factors.

The greatest inhibition was caused by mercuric ion and certain heavy metal cations; almost as inhibiting were pentachlorophenol, dicofol, 2,4,5-trichlorophenol, and DDT. Less inhibition was found with other inorganic salts, organo-metals, other organic chemicals, and some pesticides. Apart from dichromate ion, the anions studied had a low to negligible effect on lipase.
