Abstract
Amphibians have been used as bioindicators for environmental contamination because they inhabit aquatic and terrestrial realms, and their thin and highly permeable skin rapidly absorb toxic substances.
This study was performed to assess the toxic effects of copper sulfate, temephos, glyphosate, and bifenthrin on Egyptian toads and determination of some biochemical and genotoxic effects. Toads were randomly divided into 5 groups (9 toads per each). Animals in each group were exposed to either the recommended field application rates for 24 hours or 1/10 of the recommended field application rates of the tested pesticides for 96 hours. Toads treated with dechlorinated tap water and kept as a control.
