The agrochemical industry is, globally, one of the most heavily regulated industries today. Extensive product chemistry, environmental fate, residue chemistry, ecotoxicology, and mammalian toxicology data are required to support the registration and reregistration of all crop protection products. This information is used not only to conduct human dietary and worker exposure risk assessments but also to determine the potential impact of the agrochemicals and their degradation products/metabolites on the environment and sensitive ecosystems. The quality of the residue data, including the reliability and sensitivities of the analytical methods and the validity of the collected biological/environmental samples, is critical to the acceptability and validity of the risk characterization/assessment. Differences in testing guidelines between the various regulatory authorities and the lack of standardization in test method specifications further complicate the interpretation and broad application of the exposure data.
