Are amphibians (frogs, toads, and salamanders) at risk from atrazine exposure?
EPA has carefully reviewed available studies regarding the effects of atrazine on amphibians. These data do not produce consistent, reproducible effects on amphibians. Based on this assessment, the Agency concluded, and the SAP agreed, the data currently available are insufficient to make a scientifically sound determination on the potential for atrazine to impair gonadal development in amphibians. Top of page • What is the Agency doing to implement the SAP recommendations and other comments on ecological effects, including those related to amphibians? The SAP supported EPA in seeking additional data to reduce uncertainty about potential risk to amphibians. The data collection will follow the multi-tiered process outlined in the Agency’s white paper presented to the SAP. In addition to addressing uncertainty regarding the potential of atrazine to cause these effects, the studies will be helpful in characterizing the nature of any potential dose-response relationship. • What is the Agen
