Biological effects of toxic contaminants in sediments from Long Island sound and environs. Technical memo
The distribution and severity of toxicity and relationships between toxicity and chemical contamination in the sediments in Long Island Sound was determined. Samples from 20 coastal bays were tested for toxicity with three independent protocols: (1) amphipod survival, (2) survival and development of clam larvae, and (3) a microbial bioluminescence. Sediments were analyzed for heavy metals, PAHs, chlorinated pesticides and PCBs. Significant toxicity was found in each of the 20 coastal bays. Only 11 of the 60 stations showed no significant toxicity in any of the three tests. Statistical tests indicated that the toxicity observed in these samples was strongly influenced not only by gross contaminant content, but also by intrinsic sample characteristics such as grain size and TOC content.
