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.
对鱼类和贝类肌肉中的铅、镍、钒和镉进行了测定，以评估污染水平并确定生物指标。钒未检出。铅和镉略高于东南亚使用的法定限值，但低于澳大利亚和新西兰的限值。波纹巴非蛤和红树牡蛎中镍、镉和铅含量较高，棱鳀和斑节对虾中铅和镉含量较高，表明这些物种可能是水生系统中这三种金属的生物指标。生物积累模式似乎表明，生物生理学和生态学特征影响鱼类和贝类中痕量金属的生物积累。
