Two sampling sites in central Taiwan, at Hungkuang University (HKU) and Tunghai University (THU), were chosen to contrast the content of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere from November 2000 to April 2001. PAHs that arise from incomplete combustion of organic materials, especially fossil fuels, are the major toxic pollutants in central Taiwan. This study aimed to analyse PAHs, by using a PS-1 sampler and a gas chromatograph/mass selective detector (GC/MSD), and to identify the major sources of PAHs. At the HKU sampling site, the primary emission sources are probably vehicles and coal burning, and vehicular emissions are the primary contributor at the THU sampling site. [ABSTRACT FROM AUTHOR] |
