"Bioaccumulation of cadmium, lead and mercury by two species of marine polychaete worms (Nereis virens, Capitella capitata), and a clam (Macoma balthica) was assessed during prolonged laboratory exposures to four marine sediments. N. virens and C. capitata were exposed for two and three month periods respectively, and M. balthica for six months. The three sediments tested each represented a different industrialized area: a harbor drydock/ship repair facility (Vancouver Harbor); a heavily industrialized embayment (False Creek); and an area receiving pulp mill effluent discharge (Powell River). A fourth sediment collected from an area with no known sources of contamination (Bedwell Bay) served as a reference"--Summary, page vi. Marine sediments Environmental aspects British Columbia.
