Abstract
We compiled contour maps of the concentrations of major volatile organic compounds (VOCs) and corresponding chronic inhalation and carcinogenic risks in South Korea for the year 2004. We used the CALPUFF modeling system, an atmospheric dispersion model, to calculate the concentrations of five species of VOCs (benzene, ethylbenzene, styrene, toluene, and xylene). This modeling approach was used to validate the emission rates estimated in Part I of this study. The predicted concentrations show good overall agreement with the observed concentrations. In_x000D_
terms of risk assessment, we studied the chronic and carcinogenic effects on human health based on toxicity data and predicted concentrations of VOCs in ambient air. Risk levels were influenced by regional characteristics and spatial emission patterns. The results of such risk assessments could be used in support of air quality management in South Korea.
