摘要: Tadpoles of the common freshwater Sunda toad, Duttaphrynus melanostictus (Amphibia, Bufonidae), were exposed for a 4-day period under laboratory conditions to copper (Cu), cadmium (Cd), zinc (Zn), lead (Pb), nickel (Ni), iron (Fe), aluminum (Al), and manganese (Mn) at various concentrations. Mortality was assessed median times death (LT50) lethal concentrations (LC50) calculated. LT50 LC50 increased with decrease in mean exposure all metals. (96 h) Cu, Cd, Zn, Pb, Ni, Fe, Al, Mn 0.03, 0.3, 4.2, 1.5, 8.8, 0.4, 1.9, 39 mg L−1, respectively. Cu most toxic D. melanostictus, followed by (Cu > Cd > Fe > Al > Pb > Zn > Ni > Mn). is similarly sensitive these metals as other amphibian tadpoles.
