Which of the following criteria is used by EPA in establishing pesticide tolerances?

The criterion used by the EPA in establishing pesticide tolerances focuses on the toxicity of the pesticide and its breakdown products. This approach is rooted in ensuring safety for human health and the environment. The EPA assesses the potential risks associated with exposure to the pesticide and any metabolites that may form as it breaks down in the environment or within living organisms. This toxicity assessment is critical in determining the maximum residue levels that can be safely tolerated in food, water, and other environments.

By prioritizing toxicity, the EPA can set regulations that protect consumers, agricultural workers, and ecosystems from harmful effects. Establishing tolerances based on scientific investigations into the potential health risks ensures that any pesticide used does not pose an unreasonable risk when adhered to the specified limits. The focus on toxicity evaluation reflects a commitment to safeguarding public health and informs regulatory decisions concerning pesticide usage.
