Environmental Risk Assessment on Chlorination By-Products in Discharge Water from Once-Through Seawater Cooling System

Article Preview

Abstract:

Concentration analysis was performed on five chlorination by-products in discharge water from once-through seawater cooling system of Dagang Power Plant in Tianjin. In addition, toxic effects [L (E)C50] analysis was performed from three basic levels of aquatic organisms Scenedemus vacuolatus, Daphnia magna and Oncorhynchus mykiss). Based on this, the quotient method from the Technical Guidance Document (TGD) on Risk Assessment of Chemical Substances by the European Union was adopted to assess the ecological risks of five chlorination by-products in discharge water from once-through seawater cooling system. The results showed that chloral, dichloroacetic acid and pentachlorophenol had environmental risk.
