However, list of toxic substances and limit concentrations in the water environment are not consistent within management of ambient water, drinking water and industrial effluent. This article suggests the systematic framework to classify toxic substances in the water environment and deriving their effluent limits. The most important factor for decision-making to classify toxic substances is whether their concentrations in the water environment are higher than the reference concentrations, estimated by considering human health risk and ecological risk. Using a risk-based reference concentration, the ambient water quality criterion, it is possible to derive the regulatory limit concentrations of toxic substances in drinking water and in industrial effluent. The goal concentrations in the effluent, which guarantee the human and ecological safety, should be determined with scientific investigation, balancing environmental benefit and economical effect, considering availability of treatment technology and identifying characteristics of wastewater from different industries. 한국물환경학회 수질유해물질의 지정 및 배출허용기준 설정 시 고려해야 하는 복합적 요인에 대한 고찰:위해성 저감을 중심으로 The Various Factors which Should Be Considered in Classifying Toxic Substances in Water and Deriving Their Effluent Limits: Focusing on the Reduction of Risk Article 2 한국물환경학회지, v.23, no.5, pp.766 - 775 한국물환경학회지 23 5 766 775 kci ART001079766 Classification Ecological risk Human health risk Priority pollutants Toxic substances Water quality criteria Classification Ecological risk Human health risk Priority pollutants Toxic substances Water quality criteria
