Abstract
This study was carried out to characterize the atmospheric deposition of PAHs in Jeju area. For this purpose, dry and wet deposits, ambient air were analyzed. Soil samples collected around the atmospheric deposit sampling sites were also analyzed.
Dry and wet deposition fluxes of PAHs were varied from 3.07 to 30.03 and 5.01 to 37.07 μg/㎡․month, respectively. The fluxes of particle and gaseous phase of PAHs were varied from 0.42±0.70 to 3.18±2.79 and 1.20±0.16 to 2.88±0.81 ng/㎥, respectively. The average concentration of PAHs in soil were 6.72 μg/kg by dry weight.
The correlationship (R2) between total PAHs and carcinogenic PAHs were 0.5741 in dry deposition and 0.6513 in wet deposition. Also, the correlationship were 0.7885 and 0.2597 at particle and gaseous phase, respectively. Compared with the distribution of PAHs among atmospheric deposits, ambient air and soil, the distribution of 3-ring PAHs showed relatively high in ambient air and 4-ring PAHs revealed the higher level in atmospheric deposit and soil samples.
Deposition velocities of PAHs were estimated to be from 0.11 to 0.51 cm/s. 2, 3-ring PAHs with low molecular weight had relatively low velocities and 4, 5, 6-ring PAHs revealed higher relatively velocities.
Potential sources of PAHs were identified by using cross plot with FluA/(FluA+Pyr), Ant/PhA and InP/(InP+BghiP). From other cross plots it could be estimated that the glass/wood/coal combustion gave a wide-spread influence on the environment in Jeju area. However, it could not be obviously characterized the attribution of the specific sources of PAHs by the principal component analysis.
