  • This paper investigates the toxicity of cadmium (Cd) on young stages of the common Asian toad Duttaphrynus melanostictus (Schneider 1799). Signs of acute toxicity were evident in tadpoles repeatedly exposed to five concentrations ranging from 0.002 to 2 mg L−1of Cd which included environmentally relevant levels. Mortality at concentrations of 0.02 mg L−1 and above was enhanced from 2 % at 0.02 mg L−1 to 100 % at 1 mg L−1, in a dose-dependent manner. Significant growth impairment was evident at… CONTINUE READING
