The major sources of contaminants to the New York Bight apex in 1983 were sewage sludge and dredged spoils dumping and the outflow of the Hudson-Raritan estuary. Metal distributions were determined in sediments collected during a 1983 survey and metal enrichment factors, based on ratios of trace metals to iron, were used to distinguish fates of sewage sludge and dredged spoils dumped in the Bight apex. Lead enrichment factors indicated that the portion of the apex that was directly affected by dredged spoils dumping was in the immediate vicinity of that site, even though this activity constituted the largest source of solid materials to the apex. Sewage sludge dumping, in contrast, while contributing much less total mass than dredged spoils dumping, appeared to directly affect {approximately}8 times as much area.
