Abstract
Air-dispersion modeling is used in risk assessment to estimate potential exposure concentrations. This paper compares two approaches to Gaussian air-dispersion calculations. The first follows Turner’s Workbook approach using desktop calculations; the second incorporates a more complex computerized air model. A project to estimate the risk of developing a site containing PAH in the soil provided data for the comparison of the calculation approaches.
For the straightforward situation modeled here, the results were similar, both in terms of the distribution of the concentrations and the magnitude of the maximum concentration. Even though the cost was higher to obtain the computerized results, this approach may be justified in more complicated situations.
