Impact/Purpose:
To develop better field methods to detect and monitor anticholinesterase pesticide exposure of young children
Description:
Field methods are needed to detect and monitor anticholinesterase pesticide exposure of young children. Twenty children, aged 11-18 months, living in an agricultural community along the US/Mexico border were enrolled in a pilot study investigating methods to detect pesticide exposure. Children were recruited at health care clinics with the informed consent of their parent. Venous blood samples were collected from children twice, four weeks apart. Cholinesterase activity was compared in whole heparinized venous blood and venous blood samples dried on filter paper. Although the amount of activity in the dried blood was consistently less than the venous blood, the activity was significantly correlated: Spearman r2=0.6 (p=0.01). This dried blood method may be used during field studies to evaluate cholinesterase values in children.
