| Research Abstract |
This study focused on the transboundary air pollution in East Asia. Air samples were collected both in Korea(Jeju island) and Japan(Nagasaki and Okinawa). PAHs concentration in the air samples collected in winter were higher than those collected in other seasons. Toxicity(genotoxicity and acute toxicity) of the same samples were also higher in winter. Backtrajectory analysis revealed the air mass collected in Nagasaki in winter was originally from northwest China. These results suggest that PAHs was one of the causative toxicants and they originated in northeast China. However, contribution rate of PAHs to total toxicity was about 10% at most, it will be need to search another toxicants contained in transboundary air.
