Abstract
Analyses [1524] of juvenile fish collected semiannually in 144 estuaries nationwide from July 1972 through June 1976 are summarized. Pooled samples of 25 whole fish were screened for 20 common pesticides and polychlorinated biphenyls (PCB) [environmental pollutants]. The 3 most common residues, DDT, PCB and dieldrin, were found in 39, 22 and 5% of the samples, respectively. Estuarine pollution levels evidently continue to decline.
