  • Title: Study of human exposure to particulate PAHs using personal air samplers.
    Author: Kuo CY, Hsu YW, Lee HS.
    Journal: Arch Environ Contam Toxicol; 2003 May; 44(4):454-9. PubMed ID: 12712275.
    Abstract:
    Three common sources of environmental exposure to particulate polycyclic aromatic hydrocarbons (PAHs) in Taiwan were chosen for this study. They are smoke of incense burning, exhausts of motor vehicles, and fumes of charcoal burning. The campus environment without any specific PAH sources (nonpoint sources) was chosen as the control. The particulate PAH concentrations in the air samples containing smoke of incense burning were only slightly higher than those in the control. However, the total concentration of particulate PAHs in the air samples with exhausts of motor vehicles and fumes of charcoal burning was about 7.5 times and 22 times higher than those observed in the control, respectively. The mean inhalation amounts of particulate PAHs per unit time are very high both in samples with exhausts of motor vehicles (13.9 ng/min) and fumes of charcoal burning (38.1 ng/min). The exposure dose of 22 PAHs per day ranged from 3.18 to 18.0 microg/day under four exposure conditions. Moreover, the personal inhalation BaP(eq) levels are in the range of 0.4 to 1.55 microg/day.
