Background: Farm residents may be exposed to pesticide active ingredients from several non-occupational exposure pathways, including agricultural drift, para-occupational, and residential use. Quantitative, aggregate pesticide exposure metrics are needed to evaluate associations with health risks.

Objective: We are developing an active-ingredient-specific algorithm for cumulative non-occupational pesticide exposure intensity for spouses of pesticide applicators. We are quantifying the relative contributions of these pathways using meta-regression models of published data on dust pesticide concentrations.
