Age-Related Differences in Aggregate Exposures to Pesticides. C. F. Chaisson, CFC Consulting, Annandale, VA; P. S. Price, Ogden Environmental and Energy Services, Portland, Maine; and J. Y. Young, Hampshire Research Institute, Alexandria, VA
Exposures of children to pesticides differ from the exposures received from adults. These differences can result in both elevated and lowered exposures. In order to explore the quantitative impact of these differences the authors have used the LifeLineTM software to investigate how pesticide exposures vary as a function of age. The LifeLineTM software allows the modeling of individual’s pesticide exposures across their entire lifetimes. This comparison will allow the direct comparison of doses. The LifeLineTM software incorporates age-specific information on factors such as body weight, gender, mobility, dietary and activity patterns, and housing types. This information will be used as inputs to standard pesticide dose-rate models of daily exposure. The software will model each day of the individual’s lives. The dose rate estimates for each day will be used to investigate the 1-, 7-, 30-day, and annual exposures that individual’s receive when they are children (ages 1-6) an as adults (18-65). A hypothetical pesticide will be used in this example. The pesticide will be assumed to have crop and residential uses and is found as a contaminant in tap water.
