GLNPO implements a multi-media environmental management program drawing on a wide range of expertise represented by universities, private firms, State, Federal, and Canadian governmental agencies, and the International Joint Commission. The goal of the GLNPO program is to develop programs, practices and technology necessary for a better understanding of the Great Lakes Basin ecosystem and to eliminate or reduce to the maximum extent practicable the discharge of pollutants into the Great Lakes system. GLNPO also coordinates U.S. actions in fulfillment of the Great Lakes Water Quality Agreement of 1978 between Canada and the United States of America. 111 ------- CONTENTS Introduction 1 Summary 2 Conclusions and Recommendations 4 Appendices A.

Current regulations regarding approval for dredging activities require measurement of contaminant levels in the sediment and comparison of those levels with established criteria. These criteria need to be correlated with bioavailability and toxic effects of the chemicals. To date, however, no broadly applicable correlations have been defined. The lack of a definable relationship between levels of chemicals in the sediment and bioavailability of the chemicals has led to the proposal that bioassessment tests (including toxicity and bioaccumulation) be conducted for all proposed dredging operations; in fact, such procedures are currently being used for ocean dumping of dredged material. Laboratory studies have shown the potential bioavailability of both organic and inorganic contaminants from resuspended sediments, but the procedures used for bioaccumulation studies vary widely and little information is available relating the accumulation of contaminants by organisms to overall effects on the ecosystem. ------- SECTION 2 SUMMARY Because of our interest in developing methods for testing the bioavailability of contaminants, particular attention was given to laboratory tests that measure bioaccumulation of toxic substances from sediment. Many of these laboratory tests demonstrated the capability of aquatic organisms to accumulate toxic substances from sediment (3, 17, 22, 32, 53, 59, 64, 66, 68, 83, 85, 106); however, the precise extent to which this accumulation can occur remains unclear. Reported bioconcentration factors (BCF = concentrat±on i-n organisms Qr concentration in organisms concentration in sediment concentration in water depending on test) have been quite variable and are often confusing due to differences in measurement technique. Results of contaminant analysis of sediments and organisms are either reported as wet weight or as dry weight concentrations. Due to the differing amounts of water that occurs in sediments and aquatic organisms, resulting BCPs can vary severalfold depending on the basis used for calculation. Routine reporting of contaminant levels in sediments and organisms as dry weight concentrations and calculation of resulting BCFs based on dry weight concentrations would eliminate the influence of water content and reduce the variability in reported BCFs. An additional problem in interpreting the literature is that application of a BCF in bioaccumulation tests is not always indicative of the true accumulation potential. For example, tests with highly contaminated sediment (thus resulting in a large denominator in the BCF equation) may yield a low BCF even though statistically significant contaminant accumulation is occurring in the organism. Reported BCFs of less than one are therefore common in the literature even though bioaccumulation occurred in the test organism. Defining /concentration in organisms „, . , the ratio v ' as a bioaccumulation factor" concentration in sediment (BAF) rather than as a BCF (79, 106) improves the semantics of the problem, but the ultimate solution to the problem appears to involve using bioaccumulation tests that compare accumulation between organisms exposed to test sediment and organisms exposed to a control and/or reference sediment. This method of testing and reporting should produce results that have improved interpretative value in determining whether contaminants in test sediments are available for accumulation and, through proper selection of reference sediments, whether such accumulation would be expected to exceed "background levels" at specific study sites. The majority of available literature describing bioaccumulation of contaminants is directed at organic compounds such as polychlorinated biphenyls (PCBs). Research on the bioaccumulation of metals from sediments, particularly in freshwater systems, is rather limited and the results tend to be conflicting. The difficulty in differentiating between normal background levels of metals in aquatic organisms (which can be quite variable) and ------- "contaminated" levels of metals further complicates the interpretation of results. Neff et al. (63) looked at accumulation of 10 metals using five different species of test organisms and observed statistically significant uptake in 25% of the tests. Seelye et al. (83) reported that perch accumulated Pe, As, Cr, Na, Hg, Zn, Cs, and Se from naturally contaminated sediments. However, Sherwood (85) exposed fish to contaminated sediments and observed no accumulation of metals, although PCS and DDT uptake did occur. Apparently, the bioavaliability of metals from sediments is significantly influenced by several physical and chemical conditions in the sediments and water (86). ------- SECTION 3 CONCLUSIONS AND RECOMMENDATIONS Based on our review of the literature, along with our personal experience with bioassessment tests and that of investigators at other research organizations with whom we have discussed the subject, we offer the following conclusions and recommendations for consideration in the development of standardized tests of toxicity and bioaccumulation. In so doing, we recognize that several tests currently employed by various organizations were not intended to measure bioaccumulation but instead emphasize acute toxicity. We further recognize that it may not be possible to develop a single standardized test applicable to all conditions and information needs. Nevertheless, we offer the following recommendations for developing more standardized and ecologically sound test procedures for evaluating sediment quality. 1. Static tests should be avoided. Mortality to test organisms has been attributed to low dissolved oxygen conditions during static tests, a condition that may not occur in field situations. 2. Elutriate testing appears to be of questionable value in evaluating sediment quality because few correlations have been measured between the toxicity of the sediments and results of elutriate tests. In addition, the elutriate test was designed to provide information on potential "water column effects" of dredged material disposal, however, the literature we reviewed did not identify any substantial irreversible effects of dredged material disposal on planktonic organisms at the disposal site. 3. Toxicity tests on the dissolved or suspended particulate phases of dredged material appear to be of questionable value due to the lack of serious "water column effects" as stated in 2. above. The results of acute toxicity tests on these phases exhibit poor precision in general, with high mortality to control organisms being reported. As a result, only extremely high mortality to the exposed organisms will be significantly different from controls. 4. In bioaccumulation studies, steady state concentrations have rarely been attained in less than 30 days. However, it may not be necessary to attain steady state to show bioaccumulation potential. Therefore, we recommend that the 10-day period be used as recommended in the EPA/COE Implementation Manual. 5. Whole sediment (unaltered dredged material) bioassays generally show low toxicity to benthic invertebrates and fish when exposures are 10 days or less. However, longer exposures (20-50 days) have resulted in mortality of benthic organisms approaching 50 percent. Use of whole sediment allows simultaneous collection of data on toxicity and bioaccumulation of contaminants by organisms, potentially reducing the number of tests required and therefore the total cost. ------- 6. Availability of contaminants is greatly affected by physical characteristics of sediments such as particle size, distribution, total organic carbon, and mineral composition. Because the relationship between the physical and chemical characteristics of the sediment and bioavaliability of contaminants is not well defined, a site by site evaluation of sediment quality is necessary except where contaminant levels are very low. 7. Contaminant concentrations based on dry weight should be used to calculate bioconcentration factors (BCFs) and bioaccumulation factors (BAFs) in order to eliminate the influence of variable and/or changing water content in the sediments and the organisms. 8. Bioaccumulation studies should emphasize comparing the accumulation (either as a rate or as total accumulation) among organisms exposed to test sediments and organisms exposed to a control and/or reference sediment rather than relying on a BCF or BAF calculated from exposure in the test sediment. 9. Some sublethal test parameters found in the dredging literature that show promise as tools for evaluating dredged material includes invertebrate reproductive success, growth abnormalities and pathology, avoidance behavior, invertebrate metabolic rate and swimming rate, and changes in enzyme activity (e.g., catylase). 10. Toxicity data from sediment bioassays using recirculating or static water conditions are less precise than data collected using flow-through bioassay systems. .Therefore, the use of flow-through systems for both toxicity and bioaccumulation studies is recommended. 11. Organisms (including fish) allowed direct contact with sediments accumulate more contaminants than organisms not allowed direct contact with sediments. Therefore, exposure procedures that include provisions for contact between test organisms and both bedded and resuspended sediments would simulate worst-case conditions both at the dredging site and at the disposal site. 12. Bioassays conducted for ocean dumping of sediments currently must be conducted according to the methods described in EPA/CE Technical Committee, 1977 (Reference number 101 in Appendix A). Basically the protocol described in this manual includes three test procedures for laboratory bioassays: 1) acute toxicity test using elutriate water, 2) acute toxicity test using suspended particulate material from sediment; and 3) solid-phase bioassay, including a 10-day exposure of organisms to sediment with measurements of survival and bioaccumulation. The New York District of the Corps of Engineers has reported over 100 of these tests. Results from the static, acute-toxicity tests (procedure 1 and 2 above) were so variable that the personnel at the District have recommended eliminating these two procedures. Based on published results of toxicity tests we agree with this recommendation. In addition, solid-phase testing should be referred to as whole-sediment testing to insure that the fine sediment particles are not removed before the tests are conducted. ------- In summary, we recommend that: 1) A stronger link must be established between results of laboratory bioassessment tests and conditions at dredging and disposal sites. Results of laboratory bioaccumulation tests must be evaluated by comparisons with data obtained from organisms that were collected from the dredging and the disposal sites. 2) Since bioassessment procedures currently approved for use in regulating dredging include only measurements of toxicity (mortality) and/or bioaccumulation of toxic substances, we believe chronic bioassay tests should be developed for use in assessing sediment quality. 3) We recommend that work continue towards development of a single, standardized procedure for testing sediment quality. This procedure should include both measurements of toxicity and bioaccumulation in a flowing-water exposure system using more than one species of aquatic organism. Because the uptake of organic contaminants and metals is usually most rapid in benthic invertebrates that live in the sediments and are deposit feeders, we recommend use of such an organism. In addition to direct accumulation of contaminants, such as would take place in the benthic invertebrates, we believe that fish would provide an estimate of the relative amount of contaminant that may be released from the sediment and thus become available (either directly or indirectly) to the biota. When feasible, the procedure should include a species of fish that is ubiquitous in the watershed under consideration and known to feed, at least in part, on benthic invertebrates. The bioassays should be conducted with dredged material that is unaltered after collection from the area to be dredged. The organisms should be exposed to the sediments for 10 days or more under flowing water conditions. The presence of suspended solids in the test tanks would provide conditions similar to those at the dredging and disposal site during the actual dredging activity. The value of adding suspended solids during the exposure, though, must be tested before a recommendation can be made. ------- APPENDIX A ------- 1. Armstrong, D. E., J. J. Perry, and D. E. Flatness. 1979. Availability of Pollutants Associated with Suspended or Settled River Sediments Which Gain Access to the Great Lakes. EPA-905/4-79-028, U.S. Environmental Protection Agency. 102 pp. Samples of suspended sediment from 5 Great Lakes rivers were collected and analyzed for total and available concentrations of Cu, Pb, and Zn. Two methods were used for measuring available metals: a hydroxylamine hydrochloride extraction, and a resin desorption. Available metals usually ranged between 25-45% of the total metals; however, in highly polluted samples (Menominee River), as much as 76% of the total metal concentration was estimated to be biologically available. 2.

"Eggs and larvae of 6 species of anadromous and estuarine fish indigenous to the Chesapeake Bay were exposed to concentrations of suspended sediment ranging from a few mg 1-1 to 1000 mg 1-1 to determine the effects of different concentrations on hatching success and short term survival. The egg experiments indicated that concentrations of up to 1000 mg 1"1 did not significantly affect the hatching success of yellow perch, blueback herring, alewife or American shad eggs. Concentrations of 1000 mg 1"1 significantly reduced (P<0.05) the hatching success of white perch and striped bass, but lower concentrations did not. Experiments with larvae indicated that concentrations of >_ 500 mg 1~1 significantly reduced (P<0.05) the survival of striped and yellow perch larvae exposed for 48-96 h. American shad larvae appeared to be less tolerant than the other two species tested. Concentrations > 100 mg 1~1 significantly reduced the survival of shad larvae continuously exposed for 96 h. The significance of these results are discussed relative to natural and man-induced changes in sediment loading of estuaries." (author abstract) 3. Bahnick, D. A., W. A. Swenson, T. P. Markee, D. J.

Center for Lake Superior Environmental Studies, University of Wisconsin, Superior. Laboratory studies were conducted measuring toxicity and bioaccumulation, including measurements of acute toxicity tests using Daphnia magna, cough frequencies using bluegills, and bioaccumulation potential using Hexagenia limbata and chironomids. Metals, PCBs, PAHs, and DDT were measured in sediment and tissue samples and sediments were screened for organic contaminants using liquid chromatography procedures. Acute toxicity tests and bioaccumulation tests were conducted for 96 hours using either static or recirculating test conditions. Test results for the 96-hour toxicity test were variable and few differences were measured ------- between exposed and control organism survival. There were a few correlations between survival and chemical content of the sediments, but no consistent correlations were found between different organisms. The authors state that results of the acute toxicity tests showed sediments from more industrialized areas were more toxic than were those from less industrialized areas. 4. Beasley, T. M., and S. W. Fowler. 1976. Plutonium and Americium: Uptake from Contaminated Sediments by the Polychaete Nereis diversicolor. Mar. Biol., 38:95-100. The polychaete Nereis diversicolor was exposed in the laboratory to sediments naturally contaminated with plutonium and americium. Sediments collected near the Marshall Islands were contaminated by an atomic test and sediments collected from the Irish sea were contaminated from a nuclear fuel reprocessing plant. Sediments were vigorously rinsed with clean sea water prior to introduction of the polychaetes. Worms accumulated about 0.5% of the sediment concentration of both elements with a preference for plutonium. Tests were run for 40 and 225 days. 5. Birge, W. J., J. A. Black, A. G. Westerman, P. C.

Res. Rep. No. 100, University of Kentucky Water Resources Research Institute, January 1977. 28 pp. Laboratory experiments were conducted to test the effects of contaminated sediments on successful hatching of eggs of rainbow trout, goldfish, and narrow-mouthed toad. Both contaminated and clean sediments were collected from the Kentucky River system and clean sediments were spiked with varying levels of Hg, Cd, or Zn. Eyed rainbow trout eggs and newly fertilized goldfish and toad eggs were hatched in-a static bioassay system with sediment and clean water. Reduced survival to hatching and four days post-hatch was observed in all species at the lowest metal concentrations tested: 0.15, 1.34, and 104.6 yg/g for Hg, Cd, and Zn, respectively. 6.

Samples of sediments and chironomids were collected monthly for one year from four freshwater lakes in western Washington and analyzed for mercury and lead. Chironomids accumulated both metals to higher levels than the surrounding sediment for both metals. No direct correlation was observed, however, between metal concentrations in sediments and organisms. ------- 7. Boddington, M. J., A. S. W. DeFreitas, and D. R. Miller. 1979.

Brannon, J. M. 1978. Evaluation of Dredged Material Pollution Potential. Tech. Rep. DS-78-6, U.S. Army Engineers Waterways Experiment Station, Vicksburg, Mississippi, August 1978. 39 pp. This report summarizes the results of seven Dredged Material Research Program (DMRP) reports. Five of these reports are reviewed separately in the bibliography. The author's conclusions for this synthesis report are as follows: "The short term impact of dredged material on water quality and aquatic organisms is related to the concentration of chemically mobile, readily available contaminants rather than the total concentration. .. .The short term chemical and biological impacts of dredging and disposal have generally been minimal. Longer term impacts of dredged material on water quality have generally been slight and can be evaluated by means of the Elutriate Test and analysis of the mobile forms of sediment contaminants. No significantly long term increase in water column contaminant concentrations has been observed at any aquatic disposal field site. The greatest hazard of dredged material disposal is the potential effect of the material on benthic organisms." (author abstract) 9. Brannon, J. M., R. M. Engler, J. R. Rose, P. G. Hunt, and I.

Rep. 76-7, U.S. Army Engineers Waterways Experiment Station, Vicksburg, Mississippi, December 1976. 176 pp. Chemical analyses were performed on sediments collected from freshwater (Ohio), estuarine (Alabama), and saltwater (Connecticut) environments. Sediments were divided into several phases; those dissolved: 1) in interstitial water, 2) adsorbed on sediment (exchangeable), 3) occluded or co-precipitated with iron and manganese oxide and hydroxide partitions (easily reducible), 4) bound in organic matter and precipitated as sulfide salts (organic and sulfide), and 5) found in the mineral crystalline lattice (residual). Standard elutriate tests were also performed. No correlation was observed between total metal content of sediment and metal concentrations in the standard elutriate. Correlations were observed, however, between metal and nutrient concentrations in the elutriate and their concentrations in the first three sediment phases. These three phases are thought to be the most mobile in the environment. 10 ------- 10. Brewer, G. D. 1976. Resuspended Sediment Elutriate Studies on the Northern Anchovy.

"Samples of sediment from three locations in the Los Angeles-Long Beach Harbors and elutriates resulting from resuspension were assayed for heavy metals, pesticides, and other pollutants. Juvenile and adult northern anchovy (Engraulis mordax) were exposed to sediment elutriates prepared from seawater-sediment ratios between 4:1 and 100:1 for periods up to fourteen days. Toxicity varied between the three sediment samples; acute oxygen depletion was suspected as the cause of mortality. Analyses of muscle, gonad, gill, and liver tissues for silver, cadmium, chromium, copper, iron, manganese, nickel, lead and zinc from control and elutriate-exposed fish showed high levels of cadmium and zinc in fish exposed to the resuspended sediments. However, the small sample size precludes any conclusions regarding the rapid uptake of heavy metals. Sediment elutriate which had been stored for two weeks was not toxic to anchovy embryos and larvae." (author abstract) 11. Bryan, G. W., and L. G. Hummerstone. 1971.

Ann Arbor Sciences, Ann Arbor, Michigan, pp. 463-476. Laboratory bioassays were conducted with Dapnia magna and Hexagenia limbata under static-conditions in which Daphnia were suspended over sediments in beakers and Hexagenia nymphs were allowed to burrow into the sediments. Tests were conducted for 24 to 96 hours using sediments from seven locations in Lake Superior near Duluth, Minnesota. In vitro enzyme tests with four enzymes were also conducted. Toxicity and enzyme activities were measured using treated (chemically leached) and untreated sediments containing elevated levels of metals. Correlations were examined for sediment particle size, toxicity, and enzyme activity. Results show a negative correlation between metal content of sediment and particle size and also between percent inhibition of catalase activity and particle size. Correlations between percent survival of Daphnia or Hexagenia and sediment particle size show that fine sediments were lethal, independent of their metal content. 11 ------- 13. Canter, L. W., E. H.

A literature survey was conducted to determine technical deficiencies. Potential physical impacts found include changes in infiltration and flow regimes, destruction/alteration of natural or man-made habitats, and creation of habitats. Chemical impacts were found to result from the release of suspended solids, organics, nutrients, and toxic substances. Biological impacts ranged from physical barriers to fish migration to complete "smothering" of entire wetland areas. The effects of leachates on aquatic biota were found to be complex and diverse, ranging from no measurable changes to acute toxicity. Technical research needs identified in decreasing priority include studies on impact quantification and modeling, verification of predicted long-term impacts, basic chemical and biological interactions and effects, applicability of dredged material disposal findings, characterization of wetlands, and magnitude of fill discharge operations."

Krenkel, J. Harrison, and J. C. Burdick III, eds. Amer. Soc. of Civil Engineers, New York, New York. pp. 684-718. Acute toxicity tests were conducted with oyster (Crassostrea gigas) embryos (2 hours old) in the laboratory using sediments and elutriates from Grays Harbor, Washington. Deleterious effects were observed for natural sediments and sediment homologues at less than 0.1 g dry wt/1; however, no toxicity was observed in elutriates diluted by 50%. Mortality was attributed to a combination of mechanical and chemical factors. 15. Chamberlain, D. W. 1976.

Static 96-h bioassays conducted in the laboratory with elutriates of sediments collected from Los Angeles Harbor showed no significant mortality to killifish or croaker. Croaker held in elutriates for 28 12 ------- days showed bioaccumulation of some metals compared to control fish. Concentration of Zn, Pb, Cr, and Cd in exposed fish were twice as high as those in control fish. 16. Chu-Fa, T., J. Welch, K. Chang, J. Shaeffer, and L. E. Cronin. 1979.

Laboratory bioassays were performed with two species of fish, mummichogs (Fundulus heteroclitus) and spot (Leistomus xanthurus) and one mollusc (Mya arenaria), which were exposed in static systems to a series of concentrations of suspended sediment for 48 hours. Sediments were analyzed for Pb, Cr, Zn, Ca, As, PCBs, and hexane extracts. Median survival times decreased with increasing suspended sediment concentration. The relationship observed permits use of mummichog data to index gross toxicity of sediments throughout the harbor. Comparison of TLm values with benthic species diversity permitted zoning of the entire harbor into zones of high, moderate, and low toxicity. 17. Courtney, W. A. M., and W. J. Langston. 1980.

Laboratory bioassays were conducted with water samples collected from a dredging site, downstream from the dredging site, and from 3 locations within a diked disposal site in Charleston Harbor (South Carolina). Because of changing salinities, Daphnia (freshwater), Paleomonetes and Polydora (saltwater) species were tested for survival, metabolic rate, and swimming rate. Water from all sites was more toxic than control water, and water from the disposal site was most toxic. Decreases in metabolic rate and swimming activity were also observed in organisms exposed to test water when compared to controls. Disposal site water again had the greatest effect. 19. DiSalvo, L.

Sediments contaminated with 2000 ppm hydrocarbons produced about 50 to 70 ppm in mussels and crabs. The analytical procedure for hydrocarbons in tissue included a saponification procedure. Mortality was low in all tests for up to 30 days. The report is not clear as to exactly what chemicals were included in the analyses of total hydrocarbons. 20. Durant, C. J., and R. J. Reimold. 1972.

A field study was conducted examining the concentration of toxaphene in oysters before and after dredging heavily contaminated sediments in an estuarine creek.

Laboratory studies were conducted to study PCB uptake and loss by Nereis diversicolor using spiked sediment as a PCB source. Worms were placed directly in sediments under flowing seawater, sampled periodically (guts were purged of sediments), and analyzed for PCBs. Uptake phase of the tests lasted for 120 days and the elimination phase lasted 60 days. Substantial accumulation of PCBs took place, reaching a steady-state concentration after about 40-60 days. The biological half-time was calculated for this experiment to be 27 days. The authors conclude that PCB compounds in the sediment cannot be considered as being isolated from the biosphere. 23.

"Two species of polychaetous annelids (Capitella capitata and Ophryotrocha sp.) were used in a series of bioassays to determine the toxicity of resuspended sediments from fourteen stations in Los Angeles Harbor. Significant mortality did not occur in either short-term (96-hour) or long-term (28-day) bioassays using Ophryotrocha sp. Numbers of offspring were significantly reduced in all sediments except the outermost harbor station (LNG-1), indicating sublethal effects. Development success of Capitella capitata larvae ranged from 40% to 95%. The more grossly contaminated sediments yielded lower numbers of successfully developing larvae but higher growth rates in the surviving larvae. Contamination levels of the sediments correlated more closely with sediment particle size than with distance from the outside harbor. Heavy metal concentrations in the tissues of Capitella capitata did not correspond with sediment contamination levels. Resuspended sediment may result in "scavenging" which lowers the concentration of some heavy metals in the seawater." (author abstract) 25. Engler, R. M. 1980.

In: Contaminants and Sediments, Vol. 1, R. A. Baker, ed. Ann Arbor Sciences Publishers, Inc., Ann Arbor, Michigan, pp. 143-169. "Guidelines and criteria have been published (13, 14) for the ecological evaluations of the discharge of dredged and fill material into inland waters and the transportation of dredged material for dumping into ocean waters. A history of regulatory criteria development reveals that tests for describing the pollution-producing characteristics of dredged sediments were in use in the late 1960s and were similar to those used to evaluate the bulk characteristics of municipal and industrial wastes. This approach proved ineffective. Recent evaluative procedures use leaching tests for specific groups of contaminants; toxicity and bioaccumulation tests with various aquatic organisms; and general ecological evaluations of the proposed disposal sites. Implementation 15 ------- manuals have subsequently been published and are in use. Field evaluation and verification have shown these manuals to be effective environmental management tools."

Laboratory tests were conducted to estimate the release of organics to the water column upon resuspension of sediments and to determine settling times for desorbed contaminants. PCBs, DDT, and dieldrin were the most prevalent contaminants found in environmental samples. No correlation was found between PCB concentration and total organic carbon, oil and grease, or silt and clay in sediments or interstitial water. No measurable desorption of contaminants was observed at sediment to water ratios of 1:10 or lower, but desorption did occur at 1:5 ratios. PCBs remaining in 16 ------- solution after various settling times were related to suspended oil and grease and suspended solids. The highest concentration of PCBs measured in settling tests was 0.03 pg/1. 29. Gannon, J. E., and A. M. Beeton. 1969.

No. 8, Center for Great Lakes Studies, University of Wisconsin, Milwaukee. 82 pp. Laboratory bioassays were conducted with sediments collected from Buffalo, Calumet, Cleveland, Green Bay, Indiana, Rouge River, and Toledo harbors. The bioassays measured sediment selectivity by zooplankton, sediment toxicity to benthos, and effects of sediment on growth of phytoplankton based on carbon-1 4 uptake. The majority of tests were run under static conditions, some involved multiple additions of sediment, and most lasted one week or less. No correlations were evident between any biological parameter and physical measurement of sediment consisting of COD, NH4, organic N, PC>4, and volatile solids. 30. Gannon, J. E., and A. M.

Laboratory tests were conducted with Pontoporeia affinis and sediments collected from nine Great Lakes harbors to determine selectivity (sediment preference) and viability (survival after 24- or 48-h exposure to sediments). Washed aquarium sand, Fullers Earth, open lake sediments from Lake Michigan, and sediment from one of the harbors (relatively unpolluted) were used as control sediments. Although no chemical analyses were performed on either sediments or overlying water, Pontoporeia avoided sediments from harbors thought to be highly polluted. In addition, those sediments considered as polluted caused higher mortality of Pontoporeia than control sediments. 31. Gillespie, D. C., and D. P. Scott. 1971.

Laboratory studies were conducted with fathead minnows exposed to natural sediments spiked with PCBs (10 yg/g to 500 yg/g). Bioaccumulation tests 17 ------- were run under flow-through conditions; and some tests used a screen to separate the fish from the sediment, while other tests used no screen, thereby allowing contact between fish and sediment. The maximum duration of the bioaccumulation tests was 32 days. Fish allowed contact with contaminated sediment accumulated levels of PCBs (2.7 yg/g - 99.6 yg/g) six times those of the fish that were screened from contact with the sediments (0.6 yg/g - 18.5 yg/g). Desorption of PCBs from spiked sediments was also measured under static and flow-through conditions and equilibrium concentrations were related to PCB concentrations in the sediment. 33. Haven, D.

Laboratory experiments were conducted exposing oysters (Crassostrea virginica) and clams (Rangia cuneata) and Macoma balthica) to kepone-contaminated sediment from the James River (Virginia). These bivalves concentrated kepone 1000-3000 times the water concentration when sediment was resuspended. Strong correlations were observed in tests conducted over a four-week period between concentrations of kepone in oysters and in sediments and the results indicated a leveling of concentrations in animals after one week of exposure. When Crassostrea and Rangia were buried in sediment and low water flow kept sediments from being resuspended, little kepone accumulation occurred. 34. Heit, M., C. S. Klusek, and K. M. Miller. 1980.

Samples of freshwater mussels and associated sediment were collected from Lake George (New York) and analyzed for levels of trace elements, radionuclides, and polynuclear aromatic hydrocarbons (PAHs). Concentration ratios (CR—muscle tissue concentration/sediment concentration) for the three species of mussels collected were about 30 for Cd, 10 for Hg, 9 for Se, 7 for Zn, and 2 for Cu. Cr, Ni, and Pb had CRs of about 1, while As and Sn appeared not to be accumulated.

Fish were reared for up to 6 months with samples collected every 10 days. Correlations were calculated between mercury and body length of fish. The authors concluded that all fish species did not accumulate mercury at the same rate or to the same extent and therefore selected species of different ages should be used if a mercury monitoring program was implemented in Minamata Bay. 37.

Three of these reports dealt with laboratory studies examining contaminant effects. This summary report concluded that: (1) uptake of sediment-associated heavy metals by organisms was rare? (2) bulk analysis of sediments for metals did not reflect their potential environmental impact; and (3) oil and grease residues were tightly bound to sediment, making them mostly unavailable for uptake. 38.

Laboratory bioassays were conducted using sediments collected from five Lake Michigan harbors: Indiana Harbor (Indiana), Grand Haven (Michigan), New Buffalo (Michigan), Green Bay (Wisconsin), and Marinette-Menominee (Wisconsin-Michigan). Pimephales promelas, Hexagenia limbata, Lirceus fontinalis, and Paphnia magna were held in a recirculating system in the presence of the sediment. Correlations were tested between 96-hour mortality (percent) and elutriate chemical data (NH3, COD, TP, TKN, NO2» Cl~, 804=, As, Cd, Cu, Fe, Pb, Mn, Ni, and Zn). Sixty bivariate correlation analyses revealed only 4 significant correlations: mortality of P. promelas and chloride concentration, mortality of H. limbata, and concentrations of chloride, ammonia and nickel.

Jernelov, A. 1970. Release of Methylmercury from Sediments with Layers Containing Inorganic Mercury at Different Depths. Limnol. Oceanogr., 15(6):958-960. Laboratory experiments examined Hg uptake by Lebistes reticulatus held over columns of sediment in which layers were spiked with 100 yg/g HgCl2 at various depths. Along with the fish, either Tubificidae, Anodonta, or no macrofauna were added to test tanks. With no macrofauna, uptake by fish only occurred from the spiked surface sediments when mercury was available at the surface. In the presence of Tubificidae, Hg was available for accumulation down to a depth of 2 cm, while in the presence of Anodonta, Hg was available down to a depth of 9 cm. 41. Kneip, T. J., and R. E. Hazen. 1979. Deposit and Mobility of Cadmium in a Marsh-Cove Ecosystem and the Relation to Cadmium Concentration in Biota. Environ. Health Perspect., 28:67-73. "The study reported here presents the results of an investigation of a marsh-cove ecosystem heavily contaminated by cadmium. The most contaminated aquatic sediments were dredged in 1972-73, taut the resuspension of the sediments and recycle of water from the dredge spoil resulted in reestablishment of a large, contaminated sediment bed with concentrations very similar to those observed before dredging. The stability of the sediment concentrations and shallow depth of the cadmium in the sediments indicate that the deposit is relatively stable in agreement with the expectations based on the water chemistry of the system. Uptake does occur in both marsh and aquatic plants and all species of animals tested. Significantly elevated concentrations are observed compared to noncontaminated areas; however, edible portions of most fish do not appear to present a hazard. Crabs appear to present the most likely source of a hazard to humans. This potential hazard is still under investigation. The dredging removed about 5.5 MT of cadmium, about one-fourth of that originally estimated to be present, but twice that amount is found to be in the cove sediments 3 to 4 years after dredging. No appreciable improvement in the ecosystem has been made, and more careful 20 ------- consideration should be given to the need for decontamination and the method of removal of contaminated aquatic sediments in any future case."

Static bioassays were conducted in the laboratory exposing guppies (Lebistes reticulata) to sediment containing 523 ng/g (dry weight) naturally deposited Hg and additional 500 ng/g of spiked 203ng. Four groups of guppies were consecutively exposed to the same sediment for periods of 23-51 days. Continuous accumulation was observed in all groups with high individual variation (600%). No correlation between uptake and size or sex of fish was observed. In depuration studies, half-lives ranged between 38 and 75 days. 43. Kudo, A., and D. C. Mortimer. 1979. Pathways for Mercury Uptake by Fish from Bed Sediments. Environ. Pollut., 19(3):239-245. Guppies (Lebistes reticulata) were exposed in the laboratory to sediments collected from the Ottawa River (Canada) to determine the route of mercury uptake by the fish. Mercury (as mercuric chloride) was added to the already contaminated (0.523 yg/g Hg) river sediment to attain a Hg concentration of 1.023 yg/g based on dry weight. Radioactive mercury (203fjg/ 47 ciays half life) was introduced into the sediment as a tracer and analysis performed by measuring radioactivity of live fish. Exposures were conducted in a two-chambered tank connected by two glass tubes screened at both ends. This allowed water to flow between the chambers, but fish were restricted to one side or the other. In this study, sediment was introduced into one chamber and fish into one side or the other. Analysis revealed that fish in contact with the sediments accumulated 9 times more mercury than fish exposed to water alone. 44. Lang, C., and B. Lang-Dobler. 1979.

The authors collected 170 sediment samples from Lake Geneva (Switzerland) and analyzed the samples for the presence of worms and ten chemical variables (organic carbon, total P, Cd, Zn, Sn, Pb, Hg, Cu, Cr, and Mn). Fourteen tubificid and 2 lumbriculid worm species were detected in the sediment samples that were also classified by physical variables, percentage of sand, silt, and clay, and depth. Factorial correspondence analysis described relationships between worm species and chemical and physical variables. Six worm species groups were identified, each characterized by different chemical variables indicating varying levels of pollution. 45. Laskowski-Hoke, R. A., and B. L. Prater. 1981.

Some uptake of Cd by clams through 23 ------- ingestion of spiked natural sediment was observed, but the concentrations of 109cd i*1 th6 clam were never greater than 10 percent of the concentrations of 109cd in the sediment. No correlations were observed between chemical entraction of sediment and the bioavailability of lO^Cd. 53. Lyes, M. C. 1979.

"The present study was designed to determine the availability of radiolabeled 2,4,5,2',4',5', -hexachlorobiphenyl (HCBP) to taenthic amphipods from experimentally-contaminated sediments. Amphipods accumulated HCBP primarily by direct uptake from water as a function of exposure time. However, organisms that were directly exposed to the sediments had consistently higher (2.3 to 10.8X) HCBP concentrations than did organisms exposed only to the sediment-desorbed residues in the water. Experimental results demonstrated that substrate organic matter content, particle size, and sediment mineralogy affected the concentrations of HCBP in the water and, in turn, in the organisms. Removal of sediment organic matter enhanced HCBP accumulation by both substrate-exposed and water-exposed organisms. Amphipods accumulated the least HCBP when exposed to silt-clay particle size fractions which contained organic matter." (author abstract) 55. Marking, L. L., V. K. Dawson, J. L. Allen, T. D.

Fish. Res. Board Can., 35:657-664. "English sole (Paraphrys vetulus) were exposed to experimentally oiled (Alaskan North Slope crude oil) sediments over a 4-mo period to assess the bioavailability and tissue hydrocarbon distribution kinetics in flatfish. Data were also obtained on hydrocarbon related physiological changes and tissue pathology. Crude oil was mixed with aromatic hydrocarbon-free sediments to a concentration of 700 yg/g dry weight at the beginning of the experiment. During the 1st mo of the experiment this concentration decreased to 400 yg/g dry weight, and remained relatively stable during the remainder of the 4-mo period. Compositional changes were observed in the alkane and aromatic fractions, with a differential decrease in the substituted naphthalenes. Flatfish maintained in such oiled sediments readily took up alkane and aromatic petroleum hydrocarbons from these sediments, and accumulated these in skin, muscle, and liver; 1-and 2-methylnaphthalene and 1,2,3,4-tetramethylbenzene were accumulated to great extent than other aromatics. Tissue hydrocarbons decreased with time, and after 27-d continuous exposure to oiled sediments only the liver contained detectable levels of hydrocarbons. After 2 months, <2% of the initial aromatic hydrocarbon load could be detected, and only in the liver in flatfish that were continuously maintained on oiled sediments. Depuration of tissue aromatics differed for various aromatics, 1,2,3,4-tetramethylbenzene and 2-methylnaphthalene being most persistent. Depuration is thought to be due to induction of the aryl hydrocarbon hydroxylase system during initial exposure to oiled sediments. Concomitant with the high tissue hydrocarbon period were found enhanced weight loss and severe hepatocellular lipid vacuolization (HLV). Although the observations on growth changes and liver pathology are preliminary, the data indicate the need for further detailed study of fish growth abnormalities and pathology in the presence of petroleum hydrocarbons."

University of Southern California, Office of Sea Grant Programs, Allen Hancock Foundation, Harbor Environmental Projects, pp. 49-68. "Two species of crustaceans, Acartia tonsa and Tisbe sp., were subjected to the filtrate fraction (<0.45 ) of resuspended sediments from 12 stations in the Los Angeles Harbor. The 96 hour bioassays for A. Tonsa produced significant reductions in the survival rates of test groups at stations LNG-6, LNG-7, 16, 17, 18, 24 and 27. In the Tisbe bioassays, only station LNG-7 had significantly lower survival in the test group than in controls, while test group survival at stations LNG-4, -25 and -27 were significantly higher than control survival. This data suggests 25 ------- that dredging operations could have an adverse effect on the A. Tonsa population and consequently an effect on the plankton composition and food chain in the Los Angeles Harbor. However, the stations with poorest quality are in the area to be filled. Additional experiments were conducted to determine if the lined shore crab, Pachygropsus crassipes, was capable of accumulating heavy metals from resuspended sediments. Following a 7-day exposure to the sediment elutriate, the gill tissue was examined for 9 heavy metals. Because of extreme variations in the data, no discernible trends were observed."

LC5Q values were 10-80 times higher for contaminants in sediment when compared to values for contaminants in water. 59. McLeese, D. W., D. C. Metcalfe, and D. S. Pezzack. 1980. Uptake of PCB's from Sediment by Nereis virens and Crangon septemspinosa. Arch. Environ. Contain. Toxicol., 9:507-518. Two polychaete worms (Nereis virens and Glycera dibranchiota) and the shrimp Crangon septemspinosa were exposed to PCB-fortified sediments in the laboratory. Sediment PCB levels ranged from 0.04 to 0.58 mg/kg (dry). Exposure time, organism size, and sediment type were other variables tested. Authors observed that uptake by organisms was directly related to sediment concentration and inversely related to organism size. Equilibrium concentrations were not attained after 32 days of exposure and concentration factors seemed greater from sandy sediment than from muddy sediment. 60. Moore, J. W. 1981. Epipelic Algal Communities in a Eutrophic Northern Lake Contaminated with Nine Wastes. Water Res., 15(1):97:105. "The effects of contaminated bottom sediments on the species composition, growth cycles and diversity of epipelic algal communities were determined between April and November 1978 in a shallow, eutrophic lake (Thompson Lake) situated in the Canadian subarctic. The sediments had become contaminated by gold mining wastes, deposited in the lake between 1941 and 1949. Although the concentrations of total mercury, copper, lead and zinc were high near the mine, averaging 440 g kg"1, and 95, 30 and 115 mg kg~l, respectively, they decreased rapidly beyond this distance and were near background levels 2.1-3.0 km from the mine. The algal communities in the zone of heaviest contamination consisted of 63 26 ------- species, the most common of which were Anomoconeis vitrea, Pinnularia brebissonii and Cymbella species. There were more taxa (111-132) at stations situated 1.1-3.0 km from the mine and the main species included several forms of Achnanthes, Fragilaria, and Navicula. Although epipelic densities in the zone of heaviest contamination were only about 50% of those recorded at the other stations, the seasonal growth patterns of the flora were generally similar thoughout the lake. Based on these data, it is concluded that: (1) Mine wastes may have a long-term impact on epipelic algae in northern environments; (2) The effects of heavy metal pollution on the epipelon in subarctic lakes are similar to those in temperate zone systems; and (3) No species or group of species could be designated as indicators of heavy metal contamination."

Tests were run with artificial sediments spiked with radiolabled DDT using 3 species of invertebrates. Studies were run for a maximum of 25 days. A number of problems with the study were identified by the authors and the sponsoring agency. The organisms were not totally depurated before analysis, no measurements of DDT were made in the organisms before exposure, and the sediments used were composed sand, clay, and aged cereal. Accumulation of DDT was measured in all 3 species of invertebrates. 63. Neff, J. W., R. S. Foster, and J. F. Slowey. 1978.

The sediments used were altered by removal of coarse grained materials (>200 mesh). Acute toxicity tests were conducted using mayfly larvae, freshwater amphipods, and Paphnia. Bioaccumulation tests were run with fish and clams. Fish exposed to sediments accumulated PCBs, Cd, and Zn while clams only accumulated PCBs. Toxicity data were quite variable and no correlations were measured between toxicity data and analyses of chemicals in the sediment or bioaccumulation. 67. Pequegnat, W. E., R. R. Fay, and T. A.

Contain, and Toxicol., 18(2) :159-169. Laboratory bioassays were conducted using sediments collected from Duluth, Minnesota, and Superior, Wisconsin, harbors in Lake Superior. Hexagenia limbata, Asellus communis, Daphnia magna, and Pimephales promelas were held in a recirculating system in the presence of sediment. Mortality after 96-hour exposures ranged from 0 to 75%, depending on origin of sediment. D. magna were the most sensitive organisms, followed by H. limbata, A. communis, and P. promelas. Of the chemical parameters measured, no one parameter appeared responsible for observed mortality. 71. Prater, B. L., and M. A. Anderson. 1977. A 96-hr Bioassay of Otter Creek, Ohio. J. Water Pollut.

After 96-hr exposure to sediments collected in Otter Creek, Ohio, mortality was measured in Hexagenia limbata, Asellus communis, and Daphnia magna. Sediment analysis revealed high concentrations of various metals at several sampling stations; organic contaminant concentrations were mostly 29 ------- below detection limits. The apparatus consisted of a rectangular glass tank which housed the organism and sediment. Water recirculated through two, 4-liter glass jars by siphon and into the test tank via an air lift. Mortality ranged from 0 to 100% in all three organisms with D. magna being sensitive. 72. Prater, B. L., and R. A. Hoke. 1979. Statistical analyses of bulk sediment, elutriate, and bioassay sediment evaluation procedures. U.S. Army Corps of Engineers Waterways Experiment Station, Vicksburg, Mississippi. Contract No. DACW39-79-M-3098. Final Report 206 p. Recycling bioassays, bulk chemical analyses and elutriate analyses were conducted on sediments collected from five Lake Michigan harbors ranging from lightly to heavily polluted. Results of tests with three species of invertebrates and one fish species were subjected to bivariate and canonical correlations to examine which tests and parameters correlate with one another and to possibly reduce the number of chemical variables considered. The results indicated that mortality of the three invertebrate species in bioassay testing was more related to bulk sediment analyses than to elutriate chemistry. These conclusions were based mostly on heavy metals present in sediment as organic contaminants were not analyzed. Total volatile solids, oil and grease, TKN, and NH3, were found to be related to test organism mortality. Results of these tests however, may have been affected by the fact that sediments were frozen prior to testing, which may have altered sediment chemistry. 73. Prouse, N. J., and D. C.

Laboratory elutriate tests were conducted using sediments collected from the Trinity River (Texas). Acute toxicity tests (96-hr) were performed on Daphnia magna with 6 and 20% elutriates, with raw river water serving as a control. Results of these static tests revealed lowest survival by Daphnia in control water. Elutriation improved water quality by lowering the concentrations of nitrogen, phosphorus, carbon and heavy metals. The extent to which these substances were removed depended on both the saturation state and adsorptive capacity of the sediments. 75. Reimold, R. J., and C. J. Durant. 1974.

The authors found no increase in toxaphene concentrations in oysters throughout the period of dredging activity. Some increases were observed, however, in the cordgrass and mummichogs. Maximum concentrations measured in cordgrass leaves and mummichogs were 36.3 dry weight and 217.1 yg/g wet weight, respectively. 76. Renfro, W. C. 1973. Transfer of 65zn from Sediments by Marine Polychaete Worms. Mar. Biol., 21:305-316. "Silty marine sediments spiked with 65zn lose only small fractions of their radioactivity when exposed to slowly flowing seawater for several weeks. However, polychaete worms (Nereis diversicolor), burrowing through the sediment, cause 65Zn losses 3 to 7 times higher than in sediment without worms. Long-term experiments on the uptake and loss of 65zn by the polychaete Hermione hystrix indicate that 60 or more days exposure are required for this worm to approach steady state with 65zn in the sediment. Biological half-life estimates for 65zn accumulated from sediment by H. hystrix are extremely variable (52 to 197 days), depending on the loss-time interval chosen for the calculation. Following 5 days exposure to 16 cm3 of radioactive sediment, N. diversicolor individuals contained an average of 0.2% of the total 65Zn in the sediment. When these worms were transferred to non-radioactive sediment, estimates of biological half-life for *>^Zn averaged 14 to 17 days during the loss period Day 3 to Day 15. Based on these experimental results, it is estimated that a population of N. diversicolor could cause an annual loss of 3% or more of the 6^Zn in the Upper 2 cm of the sediment of a hypothetical radioactive estuary."

"The effects-based criteria identified in the 1977 ocean dumping regulations and associated guidelines for evaluating potential hazard of ocean-disposed wastes to aquatic organisms are reviewed. The use of these criteria, which provide for bioassay-based limiting permissible concentrations for physical phases of wastes to be compared with estimated environmental concentrations of the phases, is demonstrated in case studies of two wastes (acid-iron wastewater and dredged material) that are dumped in the ocean and one waste (formation water) that is discharged from an ocean outfall. The case studies present Lagrangian (exposure-time-dependent) assessments of the potential hazard of ocean-disposed wastes to plankton, as well as Eulerian (exposure-time- independent) evaluations of the potential hazard to nonplanktonic organisms. A plume study and models of different levels of sophistication are employed to estimate environmental concentrations of ocean-disposed materials" (author abstract) 31 ------- 78. Rubinstein, N.

Baker, Ed. Ann Arbor Science, Ann Arbor, Michigan, pp. 445-461. Laboratory studies were conducted using 10-gal aquaria receiving unfiltered sea water in a flow-through system. Tests were conducted for 28 days and measurements were made of survival of tnysids, shell deposition and bioaccumulation of known contaminants by oysters, substrate reworking and bioaccumulation by lugworms, and the resiliency of the benthic community in terms of numbers and variety of macrofaunal organisms that settled onto test sediments from planktonic larvae within the exposure period. Sediments containing kepone were used and effects including mortality, decreased shell growth, decreased sediment reworking, and less colonization of kepone containing sediments were observed. Oysters and lugworms accumulated kepone. The author concluded that "Introduction of this material into the marine environment, even at the lowest concentration, could have an adverse impact on marine biota at the disposal site." 79.

"Accumulation of polychlorinated biphenyls (PCBs), mercury, and cadmium by sandworms (Nereis virens), hard clams (Mercenaria mercenaria), and grass shrimp (Palaemonetes pugio) exposed to contaminated sediments from four sites in New York Harbor was studied for a 100-day period. Of the three contaminants monitored, only PCBs were found to bioaccumulate above background (control) concentrations. Small increases in PCB body burden were detected in M. mercenaria and P^. pugio, whereas higher concentrations were measured in N^. virens. Uptake was affected by the organic content of the sediment. Bioaccumulation factors (concentration in tissue/concentration in sediment) for N^. virens ranged from 1 .59 in a low organic sediment to 0.15 in a high organic sediment. Results from this study support the contention that sediment concentration alone does not reflect bioavailability and that toxicity tests (bioassays) and field monitoring remain the most direct method for estimating bioaccumulation potential of sediment-bound contaminants."

Fine grained sediments collected from Chesapeake Bay were resuspended mechanically before intermittent introduction into aquaria holding eggs. Suspended solid concentrations of 50,100 and 500 mg/1 had no effect on hatching success, while 1000 mg/1 significantly reduced success.

"Inasmuch as the process of dredging and disposing of dredged materials causes a resuspension of these materials and an increase in bioavailability of associated contaminants, we conducted a series of experiments to examine the potential accumulation by fish of contaminants from suspended sediments. In the first experiment we compared accumulation of contaminants by yellow perch of hatchery and lake origin and found that after 10 days of exposure to non-aerated sediments, fish of hatchery origin accumulated PCBs and Fe, while fish of lake origin accumulated As, Cr, Fe, and Na. Two additional exposures were conducted to evaluate the effects of aerating the sediments prior to measuring bioavailability of associated contaminants. Fish of hatchery origin exposed to non-aerated sediments for 10 days accumulated PCBs and Hg, while fish of hatchery origin exposed to aerated sediments for 10 days accumulated PCBs, DDE, Zn, Fe, Cs, and Se. These results not only demonstrated the potential for uptake of contaminants by fish as a result of dredging, but also the potential utility of fish bioassays in evaluating proposed dredging operations."

Fathead minnows were exposed in the laboratory to sediments containing acridine, a synthetic fuel by-product. Minnows were exposed to sediments containing 113 _+_ 4 yg/g acridine (dry) for 107 days. Water concentration of acridine equilibrated at about 10 yg/1. Fish concentrated acridine to 1.4 yg/g for a concentration factor (based on water concentration) of 139.5. This was equal to concentration factors found at higher water concentrations without sediment. 93. Stout, V. F., and L. G. Lewis. 1977.

Indigenous animals, English sole (Paraphrys vetulus) and pink shrimp (Pandolus borealis and P. jordani) analyzed for PCBs before and after the disposal were not found to be affected by the disposal. Additional animals were caged at the disposal site and analyzed for PCBs: spot shrimp (P. platyceros), sea cucumber (Parastichopus californicus), and mussel (Mytilus edulis). Only mussels showed a small increase in PCB concentration during disposal and the authors concluded that no obvious changes in PCB levels were occurring in Elliot Bay organisms. Initial PCB concentrations in the organisms were relatively high, however, and the PCB influx from the Duwamish River may well have masked possible bioaccumulation at the disposal site. 94.

Laboratory toxicity tests were conducted with sediments from 9 areas and with 5 marine benthic macroinvertebrates. Organisms were acclimated to control sediments, then covered with a layer of the test sediment. A continuous flow of seawater was maintained except during a one-hour period right after the test sediments were added. All tests were conducted for 10 days as required in the "Ocean Dumping Implementation Manual." Effects of burial were minimal, with all organisms showing less than 10% mortality due to burial with no substantial differences in mortality between depths of burial. The results of toxicity tests appear quite precise; however, no relationship was measured between toxicity and contaminants present. 95. Sweeney, R. A. 1978.

Test sediments were collected along the Houston Ship Channel and other Gulf Coast locations. Exposures of organisms were performed under static conditions for 8-25 days. Mortality was measured under a variety of exposure conditions, including exposures of organisms to dissolved mercury with sediments present, and exposure of organisms to sediments with high metals and organic contaminants. Results of these exposures demonstrate high variability of bioassay results. 97. Titus, J. A., J. E. Parsons, and R. M. Pfister. 1980.

In a model ecosystem, sediments were spiked with a 1 g lobule of metallic mercury. Sediment, plankton, gastropods, and goldfish were analyzed to follow movement of mercury in the system. Mercury had moved through all sediments in 7 weeks, and had equilibrated in water after 12 weeks. Detectable levels of mercury were found in plankton after 10 weeks. During weeks 12 through 40, Hg in snails and goldfish accumulated concentrations up to 1000 times that in water. 98. Trefry, J. H., R. R. Sims, Jr., and B. J. Presley. 1976. The Effects of Shell Dredging on Heavy Metal Concentrations in San Antonio Bay. In: Shell Dredging and Its Influence on Gulf Coast Environments, A. H. Bouma, ed. Gulf Publishing Co., Houston, Texas, pp. 161-184. Sediments, water, and aquatic organisms were collected from dredged and undredged areas of San Antonio Bay (Texas) and analyzed for heavy metals. Although no samples were collected during a dredging activity, the authors concluded that dredging had no effect on metal availability to organisms. This conclusion was based on the fact that metal levels in all samples from dredged areas were relatively low compared to undredged areas. 99. Trident Engineering Associates, Inc. 1977.

Static tests were conducted using a small pump to mix water and sediment in the tanks. Organisms were screened from contact with bedded sediment. Tests were run for 48 h with fish and for 96 h with clams. Bioassay results were significantly correlated with bulk measurements of metals, PCBs, and hexane extractables. A definite dose response was measured with the initial effects attributed to chemicals present, followed by physical effects adding to the chemical effects after a certain point. 100. U.S. Environmental Protection Agency. 1976. Bioassay Procedures for the Ocean Disposal Permit Program. Environmental Research Laboratory, Gulf Breeze-Narragansett-Corvallis. 96 pp. Nine laboratory procedures are described for testing the toxicity of waste materials considered for ocean disposal. Both static and flow-through tests are included. The methods cover the use of a range of trophic levels as test organisms from algae to fish. Six of the procedures are for acute toxicity measurements and the other three are termed "special" or chronic studies that are not recommended for routine use. None of the methods was designed for measuring bioaccumulation. 101. U.S. Environmental Protection Agency/Corps of Engineers Technical Committee on Criteria for Dredged and Fill Material.

This manual provides summaries and discussions of the procedures for evaluation of dredged material prior to disposal in the ocean, as required by the Federal Register. A general approach section consists of rationale behind the technical evaluation process which includes tests of liquid phase, suspended particulate phase, solid phase, bioaccumulation, initial mixing, trace contaminants, and compatibility with disposal site. Appendices in the manual provide detailed methods for the various tests. 102. Varanasi, U., and D. J. Gmur. 1981. Hydrocarbons and Metabolites in English Sole (Paraphrys vetulus) Exposed Simultaneously to 3jj Benzo[a]Pyrene and 14C Naphthalene in Oil-Contaminated Sediment. Aquat. Toxicol., 1:49-67. Sediments artificially oiled with radioactive benzola]pyrene and naphthalene in Prudhoe Bay crude oil were placed in tanks with English sole in the laboratory. After 24- and 168-h exposures, both compounds were present in tissues and major organs. Naphthalene was taken up to a greater extent than benzo[a]pyrene, although naphthalene concentrations decreased in many organs between 24 and 168 h. Benzotalpyrene was metabolized to a great extent in sole tissue. 38 ------- 103. Wentsel, R., A. Mclntosh, and V. Anderson. 1977. Sediment Contamination and Benthic Macroinvertebrate Distribution in a Metal Impacted Lake. Environ. Pollut., 14(3):187-193. Samples of sediment and benthic invertebrates were collected from five sites in a eutrophic lake in Indiana. Numbers and species of invertebrates were enumerated and sediments analyzed for Cd, Zn, and Cr. Two sites near an industrial effluent had extremely high concentrations of all three metals and were also characterized by large numbers of Limnodrilus sp. and very few chironomids. The other three sites became progressively lower in metal concentrations as they increased in distance from the point source and also exhibited decreasing numbers of Limnodrilus and increasing numbers of chironomids. 104.

The author points out the site-specificity of impacts, implying that results are not conclusive for all cases. Releases of some toxic substances were measured (PCBs, manganese, ammonia); however, no bi©accumulation was measured. No toxic effects were measured, but the author stated that they could not be ruled out. 105. Wyeth, R. K., and R. A. Sweeney. 1978.

Oligochaeta and fish were analyzed for trace metals before and after disposal. Benthos exhibited no increase in metals; however, fish showed accumulation of all metals, especially Fe, Cd, Ni, and Mn. The magnitude of the increase was correlated with concentrations in sediment. The authors also reported some unreliability of elutriate test data. 106. Yockim, R. S., A. R. Isensee, and G. E. Jones. 1978. Distribution and Toxicity of TCDD and 2,4,5-T in an Aquatic Model Ecosystem. Chemosphere, 3:215-220. Artificial silt loam soil was treated with 14C-TCDD (0.1 yg/g) or 14C-2,4,5-T (0.1, 1.0, or 10.0 yg/g) and placed in a recirculating ecosystem. Daphnia magna, snails (Helosoma sp.), algae (Oedogonium cardiacum), and fish (Gambusia affinis) were added to the ecosystem and sampled periodically from 1-32 days after introduction. Bioaccumulation ratios (tissue concentration/water concentration) of 2-6 x 10^ were measured for organisms exposed to TCDD and <50 for organisms exposed to 2,4,5-T. High mortality to G. affinis was observed in the TCDD system. 39 ------- APPENDIX B 40 ------- Accumulation s Chlorinated hydrocarbons - 3, 16, 17, 20, 22, 32, 33, 34, 54, 59, 62, 64, 65, 66, 67, 68, 75, 78, 79, 83, 85, 90, 93, 101, 106 Metals - 3, 4, 6, 7, 10, 11, 15, 16, 23, 26, 27, 31, 34, 36, 37, 40, 41, 42, 43, 46, 52, 63, 65, 66, 67, 76, 79, 83, 85, 86, 88, 96, 97, 98, 101, 105 Petroleum products - 3, 16, 19, 37, 53, 56, 92, 101, 102 Acute Toxicity Tests - 3, 5, 10, 11, 12, 14, 15, 16, 18, 19, 23, 24, 29, 30, 38, 45, 48, 49, 55, 57, 58, 65, 66, 70, 71, 74, 78, 79, 87, 88, 90, 94, 96, 99, 100, 101, 106 Community Changes - 21, 26, 35, 44, 60, 78, 88, 95, 103 Physiological Effects - 3, 12, 18, 24, 26, 29, 56, 60, 67, 73, 78, 85, 90, 100, 102 Reviews - 8, 13, 25, 37, 39, 47, 50, 61, 77, 84, 89, 91, 100, 101, 104 Sediment Chemistry - 1, 9, 28, 32, 40, 41, 51, 52, 54, 72, 83, 86, 97 Test Organisms; Aquatic plants - 26, 41, 46, 47, 60, 67, 69, 75 Benthic invertebrates - 3, 4, 6, 7, 12, 14, 16, 19, 20, 22, 23, 24, 26, 29, 30, 33, 34, 38, 40, 41, 44, 45, 52f 53, 54, 55, 57, 58, 59, 62, 63, 64, 65, 66, 67, 70, 71, 72, 73, 75, 76, 78, 79, 90, 93, 94, 97, 99, 100, 103, 105, 106 Eggs - 2, 5, 67, 80, 81, 82 Fish - 2, 3, 10, 15, 16, 17, 27, 31, 32, 36, 38, 40, 41, 42, 43, 45, 55, 56, 65, 66, 67, 68, 70, 72, 75, 83, 85, 86, 92, 93, 97, 99, 100, 102, 105, 106 Zooplankton - 3, 12, 14, 18, 29, 30, 38, 45, 55, 57, 66, 70, 71, 74, 78, 79, 87, 88, 90, 97, 100, 106 41 ------- APPENDIX C 42 ------- Allen, J.

SUPPLEMENTARY NOTES Anthony Kizlauskas Project Officer 6 ABSTRACT A literature review of sediment bioassessment was conducted as the first step in the development of a more standardized and ecologically sound test procedure for evaluating sediment quality. Based on the review, the authors concluded that 1 )a standardized laboratory bioassessment test should consistof flow-through exposure of at least 10 days duration using more than one aquatic organism including at least an infa>unal benthic invertebrate and a fish species. 2) Before adoption of a laboratory sediment bioassessment procedure, the laboratory results should be evaluated by comparison with field conditions. 3) Most current sediment bioassessment regulatory tests measure acute toxicity or bioaccumulation. Development of tests to evaluate chronic, sublethal effects is needed. 17.
