영문 초록

A study had been performed on the characteristics of air pollutants in background areas and Seoul city for the period of May and October in 96, 97. The monitoring stations of background areas were located at Mt.Sobaek, Mt.Deokyu, Mt.Jiri and other 10 urban monitoring stations were located in Seoul city. The results were as follows : 1. In background areas, ozone concentrations at Mt.Sobaek, Mt.Deokyu, and Mt.Jiri were 96.5±17.7 ppb(Seoul 23.1±19.2 ppb), 33.5±12.6 ppb(Seoul 10.2±9.6 ppb) and 59.7±18.8 ppb (Seoul 13.6±14.1 ppb), respectively. These concentrations were 3.28~4.39 times higher than those measured in Seoul. 2. In Seoul, daily variations of ozone showed a peak at 2~4 P.M. and low concentration at night time, while they didri t show much variance in background areas. 3. Air pollutant concentrations except ozone, were much lower in background areas than in Seoul ; in background areas NO₂ concentrations were 2.1~16.7 times, THC concentrations were 1.72~16.67 times lower than in Seoul. Daily variations of NO₂, THC hardly appeared in background areas. 4. Ozone was correlated positively with UV(2hours-lag time), temperature and correlated negatively with relative humidity of atmospheric factors in Seoul. Of air pollutants it was correlated positively with NOₓ, NO₂, THC with 6~8 hours, 4~6 hours, 7~9 hours lag time respectively. 5. The typical ozone daily variation of large city appeared in Seoul but there was no evidence that photochemical reaction happened at background areas.
