Neurobehavioral effects of chronic low-level pesticide exposure in children

Children living in agricultural communities face elevated health risks from chronic pesticide exposure, particularly organophosphate pesticides. Young children are especially vulnerable due to developing organ systems and limited capacity to metabolize toxins. This secondary analysis combines data collected between 1996 and 2006 from children of Latino farmworkers in Oregon. Findings show that children of agricultural workers had higher exposure to multiple organophosphate metabolites, with peak concentrations detected mid‑growing season. Children of non‑agricultural workers with multiple metabolites performed better on attention‑related neurobehavioral tests than agricultural‑worker children. These results highlight the need for stronger protections to reduce pesticide exposure in agricultural families.
