XUE, J., H. A. OZKAYNAK, V. G. ZARTARIAN, AND J. D. SPENGLER. DEVELOMENT AND EVALUATION OF A MODEL FOR ESTIMATING LONG-TERM AVERAGE OZONE EXPOSURES TO CHILDREN. Presented at ISEA/ISEE 2006, Paris, FRANCE, September 02 - 06, 2006.
Impact/Purpose:
The overall goal of this task is to evaluate, refine, and disseminate a peer-reviewed state-of-the science probabilistic model for improving estimates of human exposure and dose to multimedia, multipathway pollutants. The primary objectives of this research are the following:
Evaluate and refine the dietary (food and drinking water) exposure module and incorporate it into the SHEDS-Multimedia code.
Evaluate and refine the residential fugacity-based source-to-concentration module and incorporate it into the SHEDS-Multimedia code.
Improve the simulation of longitudinal exposure.
Develop and evaluate procedures for modeling multiple pollutants simultaneously.
Complete the SHEDS-Multimedia version 3 (aggregate) model with interface and documentation; evaluate with available data sets.
Peer review, publish, and make available the SHEDS-Multimedia model and model components.
Description:
Long-term average exposures of school-age children can be modelled using longitudinal measurements collected during the Harvard Southern California Chronic Ozone Exposure Study over a 12-month period: June, 1995-May, 1996. The data base contains over 200 young children with personal, indoor, and outdoor data, as well as time activity and other questionnaire information collected over a whole year period.
