National Benthic Surveillance Project: Pacific Coast. Organic ChemicalContaminants Cycles 1 to 7 (1984-90). National Status and Trends Program

摘要

This memorandum summarizes and interprets the status and trends of the organicchemical contaminants for 50 sites in Alaska, Washington, Oregon, and California for the years 1984-1990 and includes results of 3213 chemical analyses of sediment, fish stomach contents, fish liver, and bile samples. Thirty-one of these sites were in or near urban centers and were selected to be as representative as possible of waste inputs from multiple sources, although the sites were not necessarily representative of entire embayments. Uniform sampling protocols and state-of-the-art analytical methods have produced an extensive database, which includes detailed information on the distribution of selected polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and chlorinated hydrocarbon insecticides (CHs) in surficial sediments and stomach contents of selected species of bottom-feeding fish.
