MODELING CHILDREN'S EXPOSURE TO PESTICIDES: ISSUES AND CHALLENGS
OZKAYNAK, H. A. MODELING CHILDREN'S EXPOSURE TO PESTICIDES: ISSUES AND CHALLENGS. Presented at EPA's Workshop on the Analysis of Children's Measurements Data, Research Triangle Park, NC, September 27 - 28, 2005.
The primary objective of this research is to produce a documented version of the aggregate SHEDS-Pesticides model for conducting reliable probabilistic population assessments of human exposure and dose to environmental pollutants. SHEDS is being developed to help answer the following questions:
(1) What is the population distribution of exposure for a given cohort for existing scenarios or for proposed exposure reduction scenarios?
(2) What is the intensity, duration, frequency, and timing of exposures from different routes?
(3) What are the most critical media, routes, pathways, and factors contributing to exposures?
(4) What is the uncertainty associated with predictions of exposure for a population?
(5) How do modeled estimates compare to real-world data?
(6) What additional human exposure measurements are needed to reduce uncertainty in population estimates?
This presentation provides an overview of issues and challenges encountered in modeling children's exposures to pesticides.
