T/CSES 24-2021 Guidelines for assessing population exposure to chemical pollutants in surface water
Basic Information
Scope
Main technical content: Based on the research and management needs of environmental health risk assessment in China, and taking into account the differences in exposure assessment techniques of chemical pollutants in different environmental media, this study fully draws on advanced concepts and methods of water environmental management at home and abroad. It deeply analyzes the emission characteristics of surface water environmental pollution sources, the spatial and temporal distribution of pollutants, and other environmental impact factors. Taking surface water functional areas as the entry point, it explores the differences in water-related behavior patterns of target populations in different sub-zones and exposure scenarios, distinguishes the exposure pathways of water bodies with different water quality standards, refines and standardizes exposure assessments, and combines the experience and achievements of existing water environmental exposure assessment methods in China to propose a technical method for assessing the exposure of the population to chemical pollutants in surface water environments, which is used to evaluate the exposure of chemicals to the population in drinking water source areas, fishery water areas, landscape and recreational water areas, and water bodies with Class I to III water quality standards.
