Cholinesterase Depression and Its Association with Pesticide Exposure across the Agricultural Season among Latino Farmworkers in North Carolina

Author: Quandt, Sara A.; Chen, H., Grzywacz, J.G.
Date Published: 2010


The goal of this study was to document patterns and variation in cholinesterase levels across the agricultural season among field-workers, and to explore the association of cholinesterase depression with pesticide exposure across the agricultural season. The average cholinesterase activity levels were lowest in June, with significantly higher mean values in July and August. When adjusted for age, sex, minutes waited to shower, and days worked in the fields, the number of organophosphorus and carbamate pesticides detected in urine predicted reductions in cholinesterase activity.
