Abstract
PCB residues in fish [smallmouth bass, largemouth bass, walleye, bullheads, carp, goldfish, suckers, striped bass, salmon, rainbow or steelhead trout, lake trout] from 41 stations throughout New York State [USA] were monitored in 1975. Nearly all fish contained PCB in detectable amounts although the levels of contamination and specific Aroclor varied. The Hudson River contained the highest known PCB concentrations within USA; levels often exceeded 100 ppm. Other waters and fish which were significantly contaminated include Lake Ontario salmonids and Cayuga Lake lake trout. Onondaga Lake, previously closed to fishing because of its contamination, also appears to have abnormally high levels of PCB approaching in some instances the action level of the Food and Drug Administration, U.S. Department of Health, Education and Welfare. Samples from marine waters generally have contaminant levels substantially below 5.0 ppm.
