Zinc Cadmium Copper

Lead, copper, and cadmium exposure caused a significant, dose-dependent, increase in GST activity in gill tissue. However, liver GST only significantly increased following zinc exposure. No statistically significant effects were observed for the thiobarbituric acid reactive substances assay, indicating the absence of peroxidative damage.

    The acute toxicity of zinc, cadmium and copper to Callianassa australiensis (Dana) was evaluated in static tests. Each test lasted up to 14 d and LC50 values were calculated for 4, 7, 10 and 14 d intervals. The toxicity of each metal increased with exposure time; thus the 4 d LC50 values of 10.20, 6.33 and 1.03 mg l-1 were considerably higher than the 14 d LC50 values of 1.15, 0.49 and 0.19 mg ...
