Seasonal and spatial occurrence and distribution of atmospheric polycyclic aromatic hydrocarbons (PAHs) in rural and urban areas of the North Chinese Plain

Passive air sampling (PAS) was employed to study the occurrence of gaseous and particle-bound PAHs in the North Chinese Plain. The averaged concentrations of gaseous and particle-bound PAHs were 485 ± 209 ng/m 3 and 267 ± 161 ng/m 3, respectively. The PAHs concentrations at urban sites were generall...

Description
Summary:Passive air sampling (PAS) was employed to study the occurrence of gaseous and particle-bound PAHs in the North Chinese Plain. The averaged concentrations of gaseous and particle-bound PAHs were 485 ± 209 ng/m 3 and 267 ± 161 ng/m 3, respectively. The PAHs concentrations at urban sites were generally higher than those at rural ones with ratios
