摘要: The acute toxicity of zinc, cadmium and copper to Callianassa australiensis (Dana) was evaluated in static tests. Each test lasted up 14 d LC50 values were calculated for 4, 7, 10 intervals. each metal increased with exposure time; thus the 4 10.20, 6.33 1.03 mg l-1 considerably higher than 1.15, 0.49 0.19 respectively. Toxicity curves reveal that none asymptotic, indicating median lethal threshold concentrations not reached any metals. This suggests is an insufficient time which complete meaningful, lethality tests marine shrimps. Longer are necessary if be used application factors derive “safe” protection C. australiensis.
