Abstract
The concentrations of ambient air polycyclic aromatic hydrocarbons were measured simultaneously from August 2002 to July 2003 in an industrial area (Taichung Industrial Park) and a suburban area (Tunghai University) in central Taiwan. Particle-bound PAH were collected on quartz filters and gas-phase PAH on glass cartridges using polyurethane foam sampler. Both types of samples used soxhlet analytical method and were subjected to gas chromatography-mass spectrometric analysis. Diagnostic ratios and principal component analysis were also used to characterize and identify PAH emission source in this study.
