Heavy metal burdens in American crocodile eggs from Florida Bay, Florida
Stoneburner DL and Kushlan JA. 1984. Heavy metal burdens in American crocodile eggs from Florida Bay, Florida. Journal of Herpetology. 18(2):192-193
Samples of eggs of the American crocodile, Crocodylus acutus, were collected in 1980 from the Florida Bay portion of Everglades National Park and analyzed for heavy metal concentrations. The results were compared to studies made in 1972 and 1977. In the current study, there were no significant differences in heavy metal concentrations among the eggs sampled. The concentrations of 8 of the heavy metals were significantly higher in the shell samples than in the albumin-yolk samples; the reverse was true for mercury. The authors tentatively concluded that the mean concentration of lead and mercury in Crocodylus eggs have increased since 1972. Study Period: 1980; Study Type: Quantitative; Biological Component: Marine Reptile; Dominant Taxon/Taxa Studied: Crocodylus acutus.
