Longitudinal associations between areas of flower crops within 500m of homes and AChE activity among children (N=621, Nobs= 1149).
Circles represent the least squared means (based on repeated-measures GEE) of AChE activity for 200 quantiles of crop areas, adjusted for age, gender, parental education, height-for-age z-score, hemoglobin concentration, examination year, cohabitation with a floricultural worker, pesticide use within the residential property lot, neighbor use of pesticides on their property and examination date (days after a peak exposure period). The line represents the adjusted slope of the linear association.
Off-target drift of pesticides from greenhouses may reach people living nearby Cholinesterase inhibitor pesticides inhibit acetylcholinesterase (AChE) activity We examined 623 children (3 exams: 1156 observations) living near agriculture Home proximity to crops (within 275m) was associated with lower child AChE activity Greater crop areas within 500m (especially <150m) of homes associated with lower AChE
