초록

Air pollution has been recognized for many years as a factor which heightens the risk of cancer. Extractable polycyclic organic matters in air particulates have been recognized as to have carcinogenic effects. This study examined the health risks posed by organic substances of air particulates in Seoul based on methodelogies that have been developed for conducting risk posed by organic substances of sir particulates in Seoul based on methodologies that have been developed for conducting risk assessment of complex -chemical-mixture. The data used in this study was obtained from air samples collected in a heavy traffic area of Seoul (Shinchon) from 1986 to 1994. The mean concentration of total supended pariculates was 158.0.mu.g/m/msup 3/, 5% of which is consisted of organic matter. The excess cancer risk from benzo(a)pyrene (BaP) was estimated to be 3.48.times.10$^{-6}$ by applying BaP unit risk estimates to the mean concentration. 8.74ng/m BaP equivalents of potency method was 1.0.times.10$^{-3}$ . The calculated risk from EOM were comparably higher than that from benzo(a)pyrene and exceeded the acceptable risk level.
