Title Repeated pesticide exposure among North Carolina migrant and seasonal farmworkers
Bibliographic information 2010, Vol.53, p.802-813. 36 ref.
Abstract The objective of this study was to document the multiple and repeated pesticide absorption experienced by farmworkers in an agricultural season and their risk factors. Data were collected from 196 farmworkers four times at monthly intervals in 2007. Urine samples were tested for 12 pesticide urinary metabolites. Questionnaire data provided measures of exposure risks. Farmworkers had at least one detection for many pesticide urinary metabolites: 84.2% had at least one detection for acephate, 88.8% for 3,5,6-trichloro-2-pyridinol. Furthermore, most farmworkers had multiple detections for specific metabolites: 64.8% had two or more detections for acephate, 64.8% for 3,5,6-trichloro-2-pyridinol, 79.1% for 3-phenoxybenzoic acid, and 86.7% for 2,4-dichlorophenoxyacetic acid. Housing type had a consistent significant association with metabolite detections. Implications of these findings are discussed.
