Summary:In this study, four inorganic pollutants (cadmium, chromium, manganese, lead), that could cause contamination events in drinking water distribution system, were selected and batch tests were carried out to determine the "minimum response concentration (MRC)", a part of Korean Contamination Warning system establishment. As the results, the minimum response concentration of cadmium was found to be 0.05 to 0.08 mg/L (0.005 mg/L : water quality standard) and that of chrome was 0.03 mg/L (0.05 mg/L). And the minimum reaction concentration was 0.005 mg/L for manganese (0.05 mg / L for water quality) and 0.02~0.08 mg/L for lead (0.01 mg/L). 본 연구에서는 국내 실정에 맞는 한국형 CWS 구축의 일환으로 국내 배 급수 시스템에서 오염 사고 발생가능성이 있는 무기 오염물질 네 종류(카드뮴, 크롬, 망간, 납)를 선정하고 batch 실험을 통해 각 오염물질의 수돗물에 주입 시 감지 가능한 "최소 반응 농도(minimum response concentration)"를 결정하고자 하였다. 무기 오염물질 네 종류에 대해 수질 인자들의 최소 반응 농도를 추적한 결과 카드뮴(수질기준 0.005 mg/L)에 대한 최소 반응 농도는 0.05~0.08 mg/L, 크롬(수질기준 0.05 mg/L)에 대한 최소 반응 농도는 0.03 mg/L, 망간(수질기준 0.05 mg/L)에 대한 최소 반응 농도는 0.005 mg/L, 그리고 납(수질기준 0.01 mg/L)에 대한 최소 반응 농도는 0.02~0.08 mg/L인 것으로 분석되었다.
