Biological Assessment Methods to Predict the Impact of Open-Water Disposal of Dredged Material.

ADA060502

Publication Date	1978
Personal Author	Shuba, P. J.; Tatem, H. E.; Carroll, J. H.
Page Count	167
Abstract	This report describes numerous bioassay experiments where representative aquatic invertebrates were exposed to heavily contaminated sediments and standard liquid (elutriate) and suspended particulate phases of the sediments. The purpose of the work was to develop biological methods for assessing the effects of open-water disposal of dredged material on water column and benthic animals, prior to actual disposal. Sediments and liquid phases were analyzed for selected chemical constituents in conjunction with the bioassays. Sediment samples were collected from the Vicksburg area as well as from the Duwamish River at Seattle, the James River in Virginia, and shipping channels in New York Harbor. These materials contained a wide variety of environmental contaminants. Animals and control or reference sediments were obtained from relatively clean Gulf Coast areas or from the Mississippi River system near Vicksburg. Some organisms were obtained from other workers and cultured in the laboratory. Marine test animals included Acartia, Mysidopsis, Palaemonetes, Neanthes, Rangia, Mercenaria, and benthic amphipods and isopods. Freshwater animals included Palaemonetes (freshwater species), Daphnia, Corbicula, Musculium, and the isopod Lirceus. Survival of exposed animals was compared to control survival using statistical methods to determine a significant adverse effect. Preliminary sublethal bioassays using larval growth as the critical parameter were also accomplished.
