| Zusammenfassung: | A probabilistic carcinogenic risk assessment of atmospheric polycyclic aromatic hydrocarbons (PAHs) in four big cities (Beijing, Shanghai, Guangzhou, Xiamen) of China was carried out. PAHs levels in these cities were collected from published literatures and converted into BaP equivalent (BaPeq) concentrations. The health risk assessment models recommended by US EPA were applied to quantitatively characterize the health risk values of PAHs. Monte Carlo simulation and sensitivity analysis were applied to quantify uncertainties of risk assessment. The results showed that BaPeq concentrations of four cities were all higher than the newest limited value (1 ng/m(3)) of China. Health risk assessment indicated that atmospheric PAHs in Guangzhou and Xiamen posed no or little carcinogenic risk on local residents. However, the PAHs in Beijing and Shanghai posed potential carcinogenic risk for adults and lifetime exposure. Notwithstanding the uncertainties, this study provides the primary information on the carcinogenic risk of atmospheric PAHs in studied cities of China |
