Curl, Shirley A.A. Beresford, Richard A. Fenske, Annette L. Fitzpatrick, Chensheng Lu, Jennifer A. Nettleton, and Joel D. Kaufman Researchers often use urinary biomonitoring as the basis for estimating exposures to organophosphate pesticides (OPs), including dietary exposures. In this issue of EHP investigators report a new method to estimate long-term exposure to OPs via produce.1 This method appears to be an improvement over estimates based on urine biomarkers, which reflect exposure only in the previous few days. The researchers analyzed dietary data for nearly 4,500 men and women enrolled in the Multi-Ethnic Study of Atherosclerosis (MESA), a long-term study of cardiovascular disease risk factors in older people. Every two years participants completed a food frequency questionna...
