Abstract

Marine amphipods (Stegocephalus inflatus) were exposed to sediments artificially spiked with cadmium (0.4, 0.8, 1.6, 3.2 mg/kg) and copper (4, 12, 20, 28 mg/kg) using cadmium chloride and copper sulphate, respectively. After a 10-day exposure period, the endpoints measured included sediment avoidance and the ability of the amphipods to rebury in control sediments. Results showed that with increasing sediment concentrations of cadmium and copper there was a significant increase (P
