Abstract
Bivalve mollusks were monitored for residues of 20 organochlorine and organophosphate pesticides and polychlorinated biphenyls in spring 1977 in 87 of the 181 estuaries routinely monitored on a monthly basis during 1965-72. DDT, the only pesticide detected in 1977, occurred at low levels in 1 estuary each on the Atlantic and Pacific [USA] coasts.
