Abstract
From late 1984 to early 1985, the U.S. Fish and Wildlife Service collected a total of 315 composite samples of whole fish from 109 stations nationwide, which were analyzed for arsenic, cadmium, copper, lead, mercury, selenium, and zinc. Geometric mean, maximum, and 85th percentile concentrations (μg/g wet weight) for 1984 samples were as follows: arsenic-0.14, 1.5, 0.27; cadmium-0.03, 0.22, 0.05; copper-0.65, 23.1, 1.0; mercury-0.10, 0.37, 0.17; lead-0.11, 4.88, 0.22; selenium-0.42, 2.30, 0.73; and zinc-21.7, 118.4, 34.2. The mean concentrations of selenium and lead were significantly lower than in the previous NCBP collection (1980–81). Mean concentrations of arsenic and cadmium also declined significantly between 1976, when elemental contaminants in fish were first measured in the NCBP, and 1984. Of greatest significance, lead concentrations declined steadily from 1976 to 1984, suggesting that regulatory measures have successfully reduced the influx of lead to the aquatic environment.
