부산시의 O_3 농도 변화 특성 및 시정에 관한 연구 = Study on the Characteristics of O_3 Concentration Variation and Visibility in Pusan, Korea

다국어 초록 (Multilingual Abstract)

This study analysed O_3 concentration data and various data of meteorological factors to investigate the characteristics of O_3 concentration variation and determined how the high air pollutants concentration was generated under the meteorological condition. It also studied visibility variation and visibility impairment factors.
The characteristics of O_3 concentration variation and the characteristics of O_3 episode day(≥60 ppb) were discussed on the base of the O_3 concentration data by air quality monitoring system in Pusan. Also the characteristics of visibility variation and visibility impairment factors were studied on the base of the visibility data and meteorological data of Pusan Meteorological Administration.
According to the work, O_3 concentration was increased comparing to the previous year and coastal area was higher O_3 concentration than other area. O_3 episode day is annually increasing and the frequency of episode day is the most in summer. The high concentration of O_3 were occurred in narrow bounds and were not continued for long. Low mean wind speed were important meteorological parameter accompanying with the high episode days.
Visibility was gradually decreased until 1990 and after then it was on the increase but poor visibility range became longer than good visibility range. So many people felt air pollution more seriously. Visibility impairment were influenced by TSP concentration, NO_2 concentration, temperature, wind speed and relative humidity. Especially increase of TSP concentration and relative humidity had high generation of low visibility.
