EXPOSURE MODELING - SHEDS
Citation:
BURKE, J. M. EXPOSURE MODELING - SHEDS. Presented at Regional Air Toxics Risk Assessment Annual Meeting, Atlanta, GA, December 05, 2005.
Impact/Purpose:
The primary objectives for this task are:
to assess the contribution of outdoor sources to total personal exposures for high priority air toxics and components of particulate matter (PM),
to identify the important microenvironments and human activities contributing to high exposures for these pollutants, and
to evaluate and refine model algorithms and inputs by incorporating new approaches and data, and modularizing model algorithms for application to multiple air pollutants (particles/gases).
Description:
This presentation provides a general overview of SHEDS model features, describes algorithms in the SHEDS-Air Toxics model that focus on mobile source exposures and multipathway exposures, and presents examples of results from application of the SHEDS-Air Toxics model to benzene in Houston.
