Polycyclic aromatic hydrocarbons (PAHs) are typical organic compounds found in cigarette smoke and vehicle exhaust. In addition, PAHs are produced from incomplete combustion of organic material and cooking. The highest concentrations of PM-bound PAHs ranged from 550 ng/m3 to 39,000 ng/m3, and have been observed in Chinese kitchens, fire stations, and ships.
