  • Title: The effects of chronic cadmium exposure on American toad (Bufo americanus) tadpoles.
    Author: James SM, Little EE.
    Journal: Environ Toxicol Chem; 2003 Feb; 22(2):377-80. PubMed ID: 12558170.
    Abstract:
    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.
