Current Research Tasks
Identifying Local and Regional Source Impacts
The goal of this research is to develop and evaluate methods and models to distinguish local and regional sources of air pollution. Field and laboratory methods are used to measure the chemical composition of air pollution and these data provide the input for computer models to determine the differential impact of air pollution sources. The tools developed in this research will provide scientists and policy makers with information needed to analyze source contributions and to develop and evaluate effective control strategies.

Identifying Sources of Human Exposure
The goal of this research is to develop and evaluate methods and models to determine the impact of air pollution sources on the air people breathe. Most people in the U.S. spend a large percentage of their time indoors (>80%), yet air pollutants that originated outdoors are often present indoors. Field and laboratory methods are used to measure the chemical composition of air pollution in the air people breathe and these data provide the input for computer models to determine the impact of air pollution sources. This research will produce tools for use by researchers and policy makers to understand the relationship between air pollution sources impacting the air people breathe indoors and outdoors. When coupled with information about the resulting health impacts, the methods and models developed in this research can provide valuable data to support development of future standards to provide improved public health protection.
