Health risk assessment on citizens of inhalation exposure to environmental PAHs in Tianjin, China
Atmosphere polycyclic aromatic hydrocarbons (PAHs) may be one of the causes of lung cancer. Considering the large amounts of PAHs emitted into the ambient air in China, a preliminary health risk assessment was done to characterize the cancer risk of citizens through halation exposure to PAHs in Tianjin, China. Exposure analysis found that indoor exposure contributes more than 70％ of the daily exposure dose. And the ILCR falls within the range from 10-5 to 10-3. On the basis of sensitivity analysis results, further research should be directed to give better characterization of the indoor air concentration distribution of PAHs and the cancer slope factor (CSF) of BaP, in order to improve the accuracy of the health risk assessment.
