| Description |
The Washington State Department of Ecology is developing criteria for contaminated freshwater sediments. As part of that effort, several bioassays were tested for suitability to freshwater sediment classification. Sediments from four heavily contaminated freshwater sites were collected. Lake Roosevelt and Lake Steilacoom had high concentrations copper. Lake Washington had high concentrations of polycyclic aromatic hydrocarbons (PAH). Lake Union, an urban lake in the center of Seattle, had high concentrations of PAH and metals. Sediments from these sites were tested with Daphnia magna, Ceriodaphnia dubia, Hyalella azteca, Chironomus tentans, Hexagenia limbata, ostracods, Microtox luminosity impairment, and indigenous microbial enzyme activity. |
