광양만권 공단지역 일부 지역 주민들의 VOCs 노출농도 및 건강위해성 평가

Abstract

This research had been conducted from May to October 2007, studying 110 residents of G, Y, H industrial area in Jun-nam province. It is designed to understand the difference in levels of indoor, outdoor and personal exposure to VOCs(benzene, toluene, Ethylbenzene) and a health risk assessment was conducted to see if there was any fatal cause from carcinogenic or non-carcinogenic elements from a case group and a control group in all areas as well as each different area. In the case of benzene in the air, the geometric levels for the case group are indoor, outdoor and personal exposure; a higher than for the control group. As a results of the Monte-Carlo study about benzene, it shows that the case group’s carcinogenicity is higher than that of the control group and it also shows that, on the CTE, RME condition and Monte-Carlo analysis, all subjects are seen to exceed the carcinogenicity tolerance 10-6 of US EPA. In the case of toluene, ethylbenzene on the CTE, RME condition and Monte-Carlo analysis, these do not exceed the non-carcinogenic standard of 1, but toluene in RME condition for both groups’ personal exposure and the indoor and personal exposure of ethylbenzene in Monte-Carlo show that these seem to exceed the standard.
