This paper aims to describe the indoor-outdoor air quality in school environment through the analyses of heavy metal concentration by Inductively Coupled Plasma(ICP), which were observed at some school environment, such as traffic area, industrial area, seme-industrial area, and residence area. The results are as follows ; (1) Regardless indoor and outdoor, the area with the highest concentration of heavy metal is industrial area followed by traffic area, residence area and semi-industrial area in descending order of magnitude. And the heavy metal concentration of indoor is higher than that of outdoor. (2) The main heavy metal components with more high level concentration of indoor than those of outdoor are Zn, Al, Ca and these heavy metal concentrations are higher in class than in corridor and outdoor.
부산지역 대기질에 대한 대기 오염 지수(PSI)의 적용

The Pollutant Standards Index (PSI) was chosen as an environmental indicator. The PSI is a composite indicator computed from ambient levels of SO2 , TSP,O3 , NO2 , and CO. The daily PSI value is determined by the pollutant having the highest reading for that day. The index numbers are on a scale of zero to 500, the most important number on the scale is 100, which corresponds to the EPA - set National Ambient Air Quality Standars (NAAQS). Scores higher than 100 are considered to be unhealthful. Air quality of Pusan was evaluated by Pollutant Standards Index, which was proposed by Federal Register of the United States. The daily data of pollutants (SO2 , TSP, O3 , NO2 , CO) in 6 air pollutant monitoring sites were used for evaluation. According to the frequencies (day/day %), most parts were still under unhealthful condition. But, this result was why too many data of the high O3 concentration value in summer was missing. As the result, PSI method seems very useful to evaluate air quality, if the air quality pollutant data has no missing one, but it would be necessary to reform in consideration of environment standard of Pusan, in the case of applicating PSI in Pusan, Korea.

The purpose of this study is designed to estimate the air quality of subway stations that have the underground platforms in Pusan Metropolitan City, from September to November 2000, over seventimes. The subjects include Yonsan-dong station, Somyon station, Pusan station, Nampo-dong station, and Tushil station. The samplings were conducted at three points of each station, i.e. gate, ticket gates, and platforms. The major materials for analysis were CO, NO, NO_2, and O_3. The experiment was conducted at 7:00 pm with KIMOTO HS-seven Handy sampler and Tedlar Bag of SKC INC(U.S.A). In order to more fully understand station environments, we also measured temperature at each point. The results showed that O_3 average concentration at Yonsan-dong station was higher than others with 38~51 ppb. The average concentration of NO was high at ticket gate and platform at Somyon station(119 ppb, 122 ppb), Nampo-dong station(102 ppb, 100 ppb). These results show that the air pollution of stations with underground shopping malls was higher than others. At Somyon station having a junction station, NO and NO_2 concentration level of platform-2(noncrowded) was higher than platform-1(crowded). This is most likely due to the accumulation of air pollutants and inadequate ventilation systems.
