MEASUREMENT OF EXPOSURES TO AIR POLLUTANTS, METALS, AND PESTICIDES
OZKAYNAK, H. A. MEASUREMENT OF EXPOSURES TO AIR POLLUTANTS, METALS, AND PESTICIDES. Presented at 1st International Conference on Environmental Exposure and Health 2005, Atlanta, GA, October 05 - 07, 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?
Estimating children's health risks requires knowledge and understanding of routes and pathways of exposures to environmental agents of concern and information on concentrations of these chemicals in the relevant media or in personal air samples. This presentation summarizes the primary methods that are used for environmental and personal samples for air pollutants, metals and pesticides.
