Health risk assessment of air pollutants for some coal resource-based city

In this paper, typical coal resource-based cities at northern China were chosen to study the health risk assessment of coking industry, air pollution to residents. The results show that the industrial coking within the precincts of the individual genes in the risk of toxic substances is larger than the maximum acceptable level, and the toxic values of industrial sites in areas outside the 1 km individual genetic risk are within the maximum acceptable level, which has not a significant impact on human health. In this study, the average annual individual risk values of body toxic at 6 sensitive points are much smaller than the maximum acceptable level that will not have much impact on human health. There are some differences in the toxic substances at each point, and the main toxic substance is hydrogen sulfide.
