Abstract

In this study, we collected the tap water that treated from water plant in Seoul, Incheon, Taejon, Kwangju, Taeku and Pusan and supplied each house. The sampling period was June and September, 1997. The concentration of THMs formed by chlorination in drinking water was determined with the purge and trap method with GC/MSD recommended by the us EPA 542.2 method. Chloroform is the most of THMs (47.43%~93.11%) and the content order is bromodichloromethane > chlorodibromomethane > bromoform. In Incheon, Taejon, Kwangju, Taeku and Pusan, the content of bromodichloromethane, chlorodibromomethane and bromoform was higher than Seoul. But, in June and September, the concentration of THMs in six cities is not over Korea Drinking Water Regulation $100{\mu}g/L$. The calculated human exposure for each substances were chloroform $6.14{\times}10^{-4}mg/kg/day$, bromodichloromethane $1.01{\times}10^{-4}mg/kg/day$, chlorodibromomethane $0.29{\times}10^{-4}mg/kg/day$, bromoform $0.01{\times}10^{-4}mg/kg/day$ and THMs $7.98{\times}10^{-4}mg/kg/day$.

GC/MSD를 이용하여 우리나라의 대표적인 정수장, 즉 서울 시내의 4개의 정수장과 인천, 대전, 광주, 대구 및 부산의 정수장에서 염소처리하여 각 가정으로 보급되는 수도수를 대상으로 1997년 6월부터 9월까지 가정수에 함유되어 있는 총트리할로메탄(trihalomethanes, THMs)을 US EPA Method 524.2(Purge & Trap/GC/MSD)법을 응용하여 검출 분석하였다. 그 결과 6대 도시에서, chloroform이 THMs의 대부분을 차지하였으며(47.43%~93.11%), bromodichloromethane > chlorodibromomethane > bromoform의 순으로나타났다. 인천, 대전, 광주, 대구 및 부산은 chloroform을 제외한 나머지 물질 즉, bromodichloromethane, chlorodibromomethane 및 bromoform의 함유량이 서울보다 높게 나타났다. 그러나 6월과 9월 모두 전 지역에서 THMs의 농도는 우리 나라의 먹는 물 수질기준 $100{\mu}g/L$을 초과하는 곳은 한곳도 없었다. 또한 각 물질에 대하여 산출한 인체 노출량은 chloroform $6.14{\times}10^{-4}mg/kg/day$, bromodichloromethane $1.01{\times}10^{-4}mg/kg/day$, chlorodibromomethane $0.29{\times}10^{-4}mg/kg/day$, bromoform $0.01{\times}10^{-4}mg/kg/day$, THMs $7.98{\times}10^{-4}mg/kg/day$이었다.
