Health Risk Assessment of Polycyclic Aromatic Hydrocarbons (PAHs) in the Pearl River Delta

Abstract:

The objective of this study was to quantify PAHs exposure level for different resident groups and to estimate the incremental lifetime cancer risk for people in the Pearl River Delta. A multimedia/multipathway exposure model recommended by USEPA was employed in this study. Results indicated that the average cancer risk of exposure to PAH16 was 2.63×10-5 a-1 and the loss of life expectancy was 163.48 minutes. Considering the large amounts of PAHs emitted into the ambient environment in China and the loss of life expectancy, it is extremely important to take a preliminary health risk assessment of citizens exposed to PAHs in the Pearl River Delta.
