Bottom Line: In this study, GIS tools combined with land-use data was introduced to analyze smaller spatial scales so as to enhance the spatial resolution of the results.An uncertainty analysis using a Monte Carlo simulation was also conducted to illustrate the rationale of the probabilistic assessment mode rather than deterministic assessment.The study results could not only instruct the BaP health risk management but also help future health risk prediction and control.

ABSTRACT
Large amounts of organic pollutants emitted from industries have accumulated and caused serious human health risks, especially in urban areas with rapid industrialization. This paper focused on the carcinogen benzo[a]pyrene (BaP) from industrial effluent and gaseous emissions, and established a multi-pathway exposure model based on a Level IV multimedia fugacity model to analyze the human health risks in a city that has undergone rapid industrialization. In this study, GIS tools combined with land-use data was introduced to analyze smaller spatial scales so as to enhance the spatial resolution of the results. An uncertainty analysis using a Monte Carlo simulation was also conducted to illustrate the rationale of the probabilistic assessment mode rather than deterministic assessment. Finally, the results of the case study in Nanjing, China indicated the annual average human cancer risk induced by local industrial emissions during 2002-2008 (lowest at 1.99x10(-6) in 2008 and highest at 3.34x10(-6) in 2004), which was lower than the USEPA prescriptive level (1x10(-6)-1x10(-4)) but cannot be neglected in the long term. The study results could not only instruct the BaP health risk management but also help future health risk prediction and control.

Mentions: When the wind blew from the east, BaP emitted in the Liuhe District had little influence on the urban areas of Nanjing (Figure 4). This is mainly a result of the reasonable location of the pollution source (NCIP). In this situation, BaP cannot be directly transported by the wind to urban areas. It may, however, be transported among different compartments of nearby districts and into the Yangtze River and may consequently transport in the water flow and possibly influence the environment in urban areas. The situation may be more serious under other wind directions (for example, the pollutants may transport through the air into the urban areas when the wind blows from the north) and should be investigated.
