공업단지 주변 주민들의 주택 실내·외 VOCs, NO2 농도 및 상관성에 관한 연구

Abstract

The concentration of VOCs, NO2 was measured both inside and outside residential homes surrounding an industrialcomplex. Measurements were performed in the area of the industrial complexes and around 10 km away fromthe industrial complex area. Benzene did not exceed the air quality standard value. Toluene exhibited a high valueof concentration in outdoor Yeosu investigated group. The concentration of NO2 is higher than outsideconcentrations of houses in both inside housing research group compared with the group of Gwangyang and Yeosu. Benzene and toluene showed high correlation (p<0.001) in the housing interior in Gwangyang, It showed a highcorrelation (p<0.01) in the housing interior in the comparison group. In Yeosu there was a high correlation(p<0.001) between the inside and outside of the housing in the survey group. In the control group there was onlyhigh correlation (p<0.05) in the inside of the housing.
