Health risk-based environmental management is one of the key tasks of environmental management in China. Hazardous air pollutants (HAPs) have significant health impacts on environment and human health. Due to the lack of rapid screening method for HAPs sources in China, this study aims at developing a method for HAPs source screening based on human health concerns. On-site measurement and air model were used to estimate the emissions and the health risks of HAPs sources. The distance (D) between sources and receptors and the sensitiveness of receptor (E) are considered in this method. Therefore, a three factors (R/H-D-E) matrix for risk assessment was established in order to achieve the rapid screening of HAPs sources. We further applied this method in two specific cases, i.e., a large-scale source of chemical industrial park and a small-scale source of gas station. It shows that the results of R2-D2-E3 and H1-D2-E3 are resolved for chemical industrial park, indicating that it can be regarded as a source of high hazardous risk. For gas station, the results of R2-D1-E2 and H1-D1-E2 are resolved, pointing to a source of low hazardous risk. It suggests that this method is appropriable and applicable for the rapid screening of HAPs sources. We believe that this method may provide a support for the rapid screening of HAPs in China, which will be an asset for local and national environmental management.
