Method for diagnosing ecotoxicity of soil in polluted place, and apparatus thereof

Abstract

The invention discloses a method for diagnosing the ecotoxicity of soil in a polluted place, and an apparatus thereof. The method comprises the following steps: acquiring the basic condition of the polluted place; querying a mapping relationship between all preset land utilization modes and corresponding ecotoxicity diagnosis method sets according to the acquired polluted land utilization mode information to determine the ecotoxicity diagnosis method set mapping with the acquired land utilization mode of the polluted place; and calculating the pollution degree of the polluted land according to polluted land concerned pollutant information included in the basic condition of the polluted land and content distribution information of the concerned pollutants in soil, querying preset pollution degree mapped classification diagnosis methods, obtaining the classification diagnosis method mapping with the calculated pollution degree of the polluted land in the determined ecotoxicity diagnosis method set, and carrying out soil ecotoxicity diagnosis on the polluted land according to the obtained classification diagnosis method. The method and the apparatus are used to effectively improve the ecotoxicity diagnosis efficiency of soil.

Description

technical field [0001] The invention relates to soil ecological technology, in particular to a method and device for diagnosing soil ecotoxicity in polluted sites. Background technique [0002] Soil pollution is one of the world's environmental problems. Cleaning and safe use of contaminated soil is an important task, and soil pollution diagnosis is an important part of it. Relying solely on chemical methods for soil pollution diagnosis cannot comprehensively and scientifically characterize the overall quality characteristics of the soil, and has the following limitations: (1) It is impossible to comprehensively measure various pollutants in the soil, and cannot identify the toxic effects of all potential toxic substances , and the combined pollution effect of pollutants cannot be determined; (2) the toxic effects of these pollutants on organisms cannot be reflected only by the pollutant content; (3) it is difficult to distinguish pollutants in different exposure routes (suc...

Problems solved by technology

Relying solely on chemical methods for soil pollution diagnosis cannot comprehensively and scientifically characterize the overall quality characteristics of the soil, and has the following limitations: (1) It is impossible to comprehensively measure various pollutants in the soil, and cannot identify the toxic effects of all potential toxic substances , and the combined pollution effect of pollutants cannot be determined; (2) the toxic effects of these pollutants on organisms cannot be reflected only by the pollutant content; (3) it is difficult to distinguish pollutants in different exposure routes (such as pore water, soil air, etc.) The concentration of pollutants may underestimate the effective toxicity of pollutants; (4) the metabolic toxicity of pollutants cannot be tracked

In this way, the number of tests required for the soil ecotoxicity diagnosis of the polluted site is large, the tests are more cumbersome, the test time is long, and the efficiency of soil ecotoxicity diagnosis is low.
