Abstract In the study, skin wipe samples were collected from four typical skin parts (forehead, palm, forearm and shank) of 30 volunteers (15 men and 15 women), who work in a Petrochemical Industrial Park in Maoming City (a typical petrochemical city). The concentrations of 15 polycyclic aromatic hydrocarbons (∑₁₅ PAHs) in wiping samples were determined by gas chromatography-mass spectrometry (GC-MS), and the human exposure doses through skin exposure and hand-mouth contact were calculated. The concentration of Σ₁₅PAHs in skin samples ranged from 21 to 1.9×10⁴ng/m². The PAH concentrations exhibited significant differences among different skin parts (P<0.01) with the order of forehead>palm>forearm>shank. PAHs are mainly composed of 3~4rings. Although no statistical difference was observed in ∑₁₅ PAHs between female and male, the daily dermal absorption doses of PAH (DAD_derm) was significantly higher in female [41ng/(kg×d)] than male [28ng/(kg×d)]. The hand-mouth exposure dose [0.34ng/(kg×d)] was negligible to compare with the dermal absorption dose [34ng/(kg×d)]. The bared skins contribute to 88% of dermal absorption dose. There was no obvious non-carcinogenic risk but risks of skin cancer were higher than the acceptable level (1×10^-4) for 7% staff, indicating potential skin cancer risk.
