摘要：
Lead, nickel, vanadium and cadmium were determined in fish and shellfish muscles, to assess contamination levels and identify bio-indicators. Vanadium was not detectable. Lead and cadmium were slightly above legal limits used in South East Asia, but lower than those of Australia and New Zealand. Higher contents of nickel, cadmium and lead in Pachymelania aurita and Crassostrea rhizophorae, lead in Mugil cephalus and cadmium in Periophthalmus koelreuteri, mark these species out as possible bio-indicators for the three metals in aquatic systems. Patterns of bioaccumulation seem to suggest that biophysiological and ecological characteristics influence bioaccumulation of trace metals in fish and shell fish.
