Book Description
Excerpt from Sediment Toxicity in Reach 15 of the Upper Mississippi River: Technical Report to the Illinois Department of Natural Resources, Center for Aquatic Ecology Reach 15 of the Upper Mississippi River contains one of seven mussel refuges established by the Illinois Department of Natural Resources, formerly the Illinois Department of Conservation, and is home to the federally-endangered Higgin's-eye pearly mussel, Lampsilis higginsi (blodgett and Sparks l987a, b, and c). The refuges were established in 1988 to protect endangered or threatened mussels, to provide a source of native mussel species to repopulate other areas, and to serve as unharvested reference areas for comparison with harvested areas.

Book Description
The objective of this study was to determine the potential for polychlorinated biphenyls (PCB) and metals to bioaccumulate in the tissues of fish and invertebrates as a result of exposure to sediment from various dredging sites in the upper Mississippi River area. The acute toxicity of these sediments was of secondary interest. Water fleas (Daphnia), catfish, and bluegills were exposed to suspensions of fine-grained sediment from three test sites and one reference site for 4 to 6 days, approximately the duration of a typical dredging and disposal operation on the upper Mississippi River. Survival and tissue concentrations of contaminants in fish were determined after exposure. Fawnfoot and three-ridge clams, mayfly larvae, and amphipods were exposed to deposited sediments for up to 14 days, after which survival and contaminant concentrations in tissues of clams were determined. All three test sediments were of low toxicity to all species except the amphipods, in that no sediment produced statistically greater mortality than occurred in the controls and reference sediment. Although statistical comparisons were not made, amphipod mortality in some Upper Mississippi River sediments apparently exceeded that in the controls but probably not that in the reference sediment. Bioaccumulation was the exception, rather than the rule, with 72 species-sediment-contaminant combinations being studied and bioaccumulation potential being indicated in 8 (11 percent) of the cases. Even in these cases, resulting concentrations were below those considered likely to cause adverse impacts.
