David R. Young and Tsu-Kai Jan METALS IN SCALLOPS

Abstract

Los Angeles County's submarine discharge of municipal wastewater off the Palos Verdes Peninsula is the single largest man-related source of trace metals to the marine ecosystem off southern California. The 1974 annual mass emission rates of chromium, copper, and zinc via this discharge were approximately 400, 300, and 850 metric tons, respectively (roughly ten times the corresponding inputs measured in 1971-72 surface runoff from southern California). As a result, bottom sediments around this submarine outfall system are highly contaminated by a number of trace metals. Here we report abnormal levels of seven metals in three tissues of filter-feeding rock scallops (Hinites multirugosus) that were collected in the discharge zone and thus had been exposed to suspended wastewater particulates. (The adductor muscle of this bivalve mollusc is considered to be a delicacy, and the scallops near the discharge area sought by sport divers.)
