T/CSES 141-2024 Guidelines for Determining Ecological Thresholds of Contaminants in Shale Gas Development Land for Soil Ecology
Basic Information
Scope
Scope: This document specifies the procedures, methods, and technical requirements for determining the soil ecological thresholds of shale gas development sites. This document applies to the determination of ecological thresholds for characteristic pollutants in the soil of shale gas development sites and their surrounding areas, including nature reserves and agricultural lands in China. This document does not apply to the determination of soil ecological thresholds for pathogenic organisms, radioactive substances, and other physical pollutants (such as noise and thermal pollution). Main technical content: It mainly includes the determination procedures for soil environmental ecological safety thresholds of characteristic pollutants in shale gas development sites, exposure scenario analysis, screening of ecological receptors and ecological processes, acquisition and screening of ecotoxicity data for characteristic pollutants, threshold derivation methods, and uncertainty analysis of thresholds. It provides technical support for the determination of ecological thresholds for characteristic pollutants in the soil of shale gas development sites and their surrounding areas, including nature reserves and agricultural lands in China.
