Abstract Concentrations of silver, arsenic, cadmium, chromium, mercury, manganese, lead, and zinc were determined for selected marine fish and shellfish collected at or near three ocean disposal sites, a control site and three inshore areas of the middle eastern United States. The disposal sites were off New Haven, Connecticut; New York City, and Delaware Bay. The control site was at Chincoteague Inlet, Virginia, and other areas were in Long Island Sound (near the New Haven disposal site); Barnegat Bay, New Jersey, and a second area off New York City near the Bight apex disposal site. With the following exceptions, the amounts of trace metals in biological samples did not vary substantially among the geographic areas: Silver in rock crab flesh averaged 0.79 ppm for the New York Bight disposal site compared with 0.24 to 0.38 ppm for four other areas. Cadmium, manganese, and zinc concentrations were greatest in rock crab flesh collected from Long Island Sound area 2 (not a known disposal site) compared to three other areas; mean levels were 1vs. 0.1 ppm, 29vs. 0.8 to 1 ppm, and 64vs. 32 to 36 ppm. The manganese content in gills of rock crabs from the same area in the Sound was 22 ppm compared with 6 ppm for Chincoteague Inlet. Digestive glands of channeled whelk collected from a disposal site in Long Island Sound contained the greatest amount of silver, cadmium, and zinc compared to the control area, Chincoteague Inlet, and a site outside the disposal area in the Sound. Levels were 20vs. 6 to 7 ppm of silver, 24vs. 16 and 17 ppm of cadmium, and 2650vs. 1,025 and 405 ppm of zinc, respectively. In addition, whelk digestive gland from the two areas in the Sound contained about 1,100 ppm of copper compared to only 32 ppm for Chincoteague Inlet. Trace metal concentrations in the organisms used during this study were of the same order of magnitude as those reported by various investigations for a variety of organisms collected from waters in the U.S. Atlantic and Pacific as well as in British waters of the Atlantic.
