The effects of chronic cadmium exposure on American toad (Bufo americanus) tadpoles.
American toad (Bufo americanus) tadpoles were exposed to cadmium from shortly after hatching through metamorphosis. Cadmium at 540 microg/L decreased percentage survival and metamorphosis; 5 and 54 microg/L increased growth relative to controls. Amphibians exposed to cadmium as tadpoles may be less tolerant of natural stressors in the terrestrial environment.
