The average concentration of PM1 = 160.16 ± 37.70 μg/m3.
Toxic equivalency factors of ∑7PAHcarcinogen contributes 98.51% of total PAHs.
ILCR of B[a]P and Dibenz (a, h) anthracene was relatively much higher than other carcinogenic PAHs.
High total ILCR for both adults and children.
Diesel emission, combustion and long range transport are main sources for PAHs.
