OBJECTIVE: To identify and to discuss some of the major risks associated to pesticide use in the soybean production in Mato Grosso State, Midwestern Brazil. METHOD: It is a descriptive exploratory pilot-study that was carried out between 2008 and 2009, using methodological triangulation, comprising the following: analysis of an agricultural database, analysis of biological indicators of pesticide exposure, and analysis of rainwater contamination by these chemicals. RESULTS: Analysis of pesticides consumption data showed a high and growing use of pesticides in soybean production, particularly glyphosate. Rainwater analysis evidenced the occurrence of different pesticide residues, indicating the amplification of the risks beyond workplace. This environmental exposure was also detected by biological indicator analysis among workers and residents of the plantation neighboring areas. CONCLUSION: The study data indicate the need for permanent environmental and human health monitoring in soybean production areas as part of workers' health and environmental surveillance strategies.
