This work characterizes cumulative intake of organophosphorous (OP) pesticides in an agricultural population of California by drawing on human biomonitoring data, pesticide use reporting (PUR) data, limited environmental samples, and an indoor/outdoor mass balance exposure model (CalTOX). We use an indoor fate/exposure model with outdoor air and soil concentrations obtained from monitoring data and a regional fate model. Samples of indoor air, dust and surface concentrations have been obtained in a limited number of houses for this population. Model results help explain how these concentrations arise. We find that both food and the indoor environments play a key role in delivering OPs to the Salinas population. This seminar will share the information presented at the recent EET Division Review meetings. For more information about this seminar, please contact: Hugo Destaillats(510) 486-5897
