ABSTRACT

PM₁₀ (particulate matter which passes through a size selective impactor inlet with a 50% efficiency cut-off at 10 µm aerodynamic diameter) and PM_2.5 were collected at four sites (A: Xiaoping, B: Huli, C: Hongwen, D: Gulang Island) from December 20, 2004 to December 29, 2004 in Xiamen. 16 Priority polycyclic aromatic hydrocarbons (PAHs) in PM₁₀/PM_2.5 were quantified by using a gas chromatograph/mass spectrometer (GC/MS). EC and OC of PM₁₀ were analyzed by Thermal/Optical Carbon Analyzer (DRI Model 2001). Concentration, spatial distributions of PAHs and EC/OC were studied and their main sources were identified by diagnostic ratios, correlation analysis and EC/OC analysis. Among the different sampling sites, concentrations of Σ16PAHs were 5.20-28.07 ng/m³ in PM₁₀ and 3.04-11.32 ng/m³ in PM_2.5. Concentration of OC were 9.83-15.6 μg/m³ and 1.41-4.73 μg/m³ for EC associated to PM₁₀. The main sources identified were traffic emissions and industry emission/coal combustion.
