Scope

Scope: This document stipulates the procedures for establishing sediment quality benchmarks for watershed water environments, the collection and screening of data, the derivation of sediment quality benchmarks, validation and review, and application. This document is applicable to guiding the establishment of sediment quality benchmarks for watershed water environments (freshwater rivers and lakes) in China. Main technical content: Based on the progress and development needs of sediment quality benchmarks in watershed water environments in China, this study conducts research on the derivation methods and application of sediment quality benchmarks for watershed water environments, providing a basis for scientifically establishing sediment quality thresholds for surface water environments in watersheds and protecting benthic organisms and related water environmental functions. Specific technical content includes: (1) Scope; (2) Normative reference documents; (3) Terms and definitions; (4) Procedures for establishing sediment quality benchmarks; (5) Data collection and screening; (6) Derivation of sediment quality benchmarks; (7) Validation and review of sediment quality benchmarks; (8) Application of sediment quality benchmarks.
