Iterative use of a priori exposure matrices to improve the characterization of chemical exposures in agricultural work studies.
To assess pesticide exposures of agricultural workers, a priori exposure matrices based on « circumstantial determinants » of pesticide use were incorporated into the questionnaire of a case-referent study.
Circumstantial determinants (crops cultivated, their surface areas and crop infestations) were recalled more frequently than specific chemicals.
After the matrices were applied, the proportion of missing values fell from 44 to 9% for specific chemicals, from 97 to 17% for the dose for each treatment, and from 80 to 16% for number of treatments per year in a random sample of 40 questionnaires.
