The aims of this study were to assess the knowledge, attitudes, and practices regarding the use of
pesticides by farmers in two rural settings in Midwestern Brazil, and to determine the levels of
exposure of farmers and residents to organophosphorous and carbamate pesticides through AChE and
BChE analysis. This is the first time that a KAP/biomonitoring study has been conducted in an
agricultural setting in this region of the country.
