Ozkaynak, A H. OVERVIEW OF EXPOSURE FACTORS RESEARCH AT EPA OFFICE OF RESEARCH AND DEVELOPMENT NATIONAL EXPOSURE RESEARCH LABORATORY (NERL). Presented at Exposure Factors Program Peer Involvement Workshop, Washington, DC, June 7-8, 2004.

Impact/Purpose:

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?
