ANDRADE, André Santana et al. Risk analysis of water contamination by pesticides in Alto Paranaíba, MG, Brazil. Quím. Nova [online]. 2011, vol.34, n.7, pp.1129-1135. ISSN 0100-4042.

A preliminary analyses of the possible contamination of surface and groundwater by the active ingredients of the pesticide products used in the areas with intensive agricultural activities of Alto Paranaíba region, MG, Brazil, was carried out. The active ingredients and formulated products most used in the region were identified and their characteristics of environmental importance were presented. The EPA screening criteria, the groundwater ubiquity score (GUS) and the criteria proposed by Goss were used to evaluate which pesticides might contaminate the local waters. Among the active ingredients studied, several present risks to the local aquatic environment.
