Assessing Genotoxicity and Mutagenicity of Three Common Amphibian Species Inhabiting Agroecosystem Environment.

Amphibians are constantly exposed to pollutants and the stress of agricultural activities. We selected three anuran amphibian species Dendropsophus minutus, Boana albopunctata, and Physalaemus cuvieri, totaling 309 individuals. We collected tadpoles in 15 permanent ponds: 5 soybean crops, 3 corn crops, and 7 nonagricultural lands.

Genotoxic and mutagenic effects of Atrazine Atanor 50 SC on Dendropsophus minutus Peters, 1872 (Anura: Hylidae) developmental larval stages.

The potential mutagenic and genotoxic effects of the herbicide atrazine were investigated in different developmental stages of Dendropsophus minutus tadpoles. These animals were exposed to 4 nominal concentrations of atrazine (2.25, 4.
