Evaluating Cumulative OP Pesticide Body Burden of Children

A National Case Study

Categorized Under: Environment, Health, Scientific + Engineering Analysis



Published in the journal Environmental Science & Technology on September 15, 2009, by Jonathan Cohen of ICF International, co-authored with the U.S. Environmental Protection Agency. The objectives of the study were to develop a methodology for a health risk interpretation of biomonitoring data and to apply it using NHANES 1999-2002 body burden data for organophosphorus (OP) pesticides. OP pesticides present a particularly challenging case given the nonspecificity of many metabolites monitored through NHANES. The results suggest that approximately 40 percent of children in the United States may have had insufficient margins of exposure (MOE) for neurological impacts from cumulative exposures to OP pesticides (MOE less than 1000). The paper was given an Editor's Choice Award as Best Paper of 2009, 2nd Runner up, category Science.
