Scope
Main technical content: In response to the environmental management needs of water environmental risk assessment in river basins, and according to the two different types of risk assessment, namely sudden-type risk and cumulative-type risk, focusing mainly on chemical pollutants in surface water, a methodological system for ecological risk assessment of water environment in river basins was established. The key techniques of risk assessment, including risk identification, risk characterization, uncertainty analysis, and risk assessment conclusions, were clarified. The specific technical content includes: (1) Scope; (2) Normative reference documents; (3) Terminology and definitions; (4) General principles of ecological risk assessment; (5) Development of assessment schemes; (6) Risk identification; (7) Risk assessment; (8) Uncertainty analysis; (9) Risk assessment conclusions; (10) Appendix A: Risk grading by matrix method; (11) Appendix B: Calculation of risk levels by formula method
