Abstract
|
|
|
|
Air samples were collected and analyzed to investigate regional level of PAHs and its emission sources. The average concentrations of PAHs in the suburban (Gwanak) and in the urban (Seodaemun) area were 16.5 ng/㎥ and 59.1 ng/㎥, respectively. Phenanthrene, fluoranthene, pyrene, and fluorene were predominant PAHs species, as their sum contributed to 55.6% and 60.8% of the total PAHs, respectively. The possible major source of PAHs was suspect to be the combustion of diesel fueled vehicles in both areas, particularly for Seodaemun.
