OEH Seminar: Estimating potential pesticide exposure at the population level in Canada

Pesticide exposure may relate to certain cancer outcomes, reproductive health issues, adverse birth outcomes, neurological concerns and other more general health problems. The purpose of this study was to generate national population-level exposure estimates for three commonly applied pesticides that are suspected carcinogens. Using geographic information systems, pesticide exposure was estimated for every - census subdivision (CSD) in Canada (n=5,054) by combining raster-based surfaces for the distribution of crops with average crop-specific pesticide application rates. Analyses examined all crops in combination with different pesticide application rates to obtain a cumulative potential total exposure. Results demonstrate that the population exposure varies greatly depending on agricultural production.
