Problems solved by technology

[0003] There is currently a lack of exposure area identification technology to support the environmental priority management of river pollution
In terms of environmental health risk management methods for water pollution in river basins abroad, there is no technical method for determining population exposure areas for environmental health risk assessment of river pollution characteristic pollutants; Systematic research is very weak

Embodiment Construction

[0057] Such as figure 1 As shown, the present invention provides a method based on the screening of characteristic pollutants, the simulation of the pollution status of target characteristic pollutants, and the analysis results of pollution causes. On the basis of clarifying the target characteristic pollutants and corresponding affected media, the potential environmental health risk bias of the exposed population is determined. High spatial range approach. Hereinafter, the present invention will be further described in detail by taking the main environmental health sensitive area of ​​S area as an example. Specific steps are as follows:

[0058] 1. Sampling distribution situation

[0059] 1.1 Sampling point layout

[0060] According to the random method of the system, within 3000 meters on both sides of the bridge section of the S area of ​​the A river and the B river, the total area is 483.93Km 2 Set up sites in environmental health sensitive areas. The soil points are ...

Abstract

The invention relates to a method for determining a population exposure area according to environmental health risk assessment on river pollution specific pollutants and application of the method, and belongs to the field of environmental science and health risk assessment. According to the method disclosed by the invention, by comprehensively considering a specific pollutant screening result, a pollution status simulation result of target specific pollutants and a pollution cause analysis result, pollution status simulation and exposure area determination are performed by adopting spatial analysis software, and an area range that the potential environmental health risk of an exposed population is high is artificially determined. According to the method disclosed by the invention, a technical support can be provided for the environmental health risk assessment and management on river pollution.

Description

technical field [0001] The invention relates to the fields of environmental science and health risk assessment, and is a method for determining the exposure area of ​​a population in the environmental health risk assessment of river pollution characteristic pollutants and its application, more specifically, a method that comprehensively considers the screening results of characteristic pollutants and their pollution status space Analyze the results and determine the potential environmental health risks of the exposed population through data processing, especially the method of determining the range of areas with high environmental health risks. Background technique [0002] Determination of characteristic pollutant exposure areas is the technical premise for carrying out environmental priority management. At present, environmental pollution is a problem that human development must face, and it has the characteristics of long-lasting pollution and difficult treatment. Effect...
