Problems solved by technology
However, this method is aimed at a specific exposure scenario under a specific use of a specific polluted land, and the applicable scale is small, so it is not suitable for the identification of high-risk soil pollutants at the regional level. In addition, the evaluation object only covers the health risks of the population, and soil pollutants are not considered Ecological hazards, migration, persistence and other factors

Embodiment Construction
[0018] The present invention will be further described below in conjunction with specific examples.
[0019] Such as figure 1 As shown, the present invention provides a method for identifying high-risk pollutants in the regional soil environment.
[0020] This embodiment identifies high-risk pollutants in the soil environment of a chemical industry park, including the following steps:
[0021] Step 1. The chemical park covers an area of about 2 square kilometers and is mainly composed of enterprises in the fine chemical industry. A list of potential soil pollutants is formed by sorting out the raw and auxiliary materials and pollutants emitted by the production activities of various industrial enterprises in the park. There are a total of 30 potential soil pollutants, including benzene, toluene, ethylbenzene, chlorobenzene, and o-xylene , m-xylene, p-xylene, 1,2-dichlorobenzene, 1,4-dichlorobenzene, 1,2,4-trichlorobenzene, dichloromethane, 1,2-dichloroethane, 1,2 -dichlorop...

The invention discloses a method for identifying high-risk pollutants in a regional soil environment, which comprises the following steps: step 1, collecting a list of potential soil pollutants according to the production activities of enterprises in the region; step 2, arranging point sampling, and comparing the list of potential soil pollutants Detection and analysis; Step 3, the detection rate and the exceeding rate of the pollutants detected by statistics, and normalized processing; Step 4, according to the formula R 1 =X 1 ×a+X 2 × b to calculate R 1 ;Sort from high to low and select the top 10 to form a list of candidate pollutants; Step 5, establish a comprehensive scoring system, including carcinogenicity, non-carcinogenic health toxicity, ecotoxicity, biodegradability, mobility and volatility of pollutants, select The characterization indicators of each scoring factor are graded and assigned, and the scoring factors of comprehensive pollutants are assigned values, and the top 5 most polluted pollutants are selected to form a list of high-risk pollutants; Step 6: Regularly monitor and control the list of high-risk pollutants. The invention has the advantages of high efficiency, comprehensive measuring indexes and the like.
Description
technical field [0001] The invention belongs to the technical field of soil pollution prevention and environmental risk identification, and relates to a method for identifying pollutants in a soil environment, in particular to a method for identifying high-risk pollutants in a regional soil environment. Background technique [0002] As an important natural resource, soil provides the most basic material basis for the survival of organisms and the development of human society. At the same time, the soil environment is also affected by natural factors and human activities, and has become a "sink" of various pollutants including heavy metals and organic matter. Soil environment is closely related to the safety of living environment and food safety, so it is increasingly concerned by management departments and the public. In order to strengthen pollution supervision and do a good job in pollution prevention, it is necessary to build a soil environmental quality monitoring netwo...
