I. Experimental methods
Air samples were collected by using a high-volume air sampler at 1000 L min-1 for 12–24 h.
The concentration of total suspended particulates (TSP) was determined from the weight of materials collected on filter.
15 polycyclic aromatic hydrocarbons (PAHs) were analyzed by using high-performance liquid chromatography.
15 PAHs include phenanthrene, antracene, fluoranthene, pyrene, benz[a]anthracene, chrysene, retene, benzo[e]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenz[a,h]anthracene, benzo[g,h,i]perylene, indeno[1,2,3,c,d]pyrene, and coronene.
20 n-alkane molecules (Cn: n = 15–35) were analyzed by using gas chromatography–mass spectrometry.
