Method and apparatus for optimizing soil ecotoxicity diagnosis result of contaminated site

Abstract

The present invention discloses a method and an apparatus for optimizing a soil ecotoxicity diagnosis result of a contaminated site. The method comprises: acquiring a soil ecotoxicity diagnosis result, and searching a mapping table of toxic effects versus contamination values to obtain a contamination value mapping a toxic effect corresponding to the soil ecotoxicity diagnosis result; acquiring an experiment classification of a diagnostic experiment according to a toxicity experiment classification table, and searching for a mapping table of experiment classifications versus experiment weight coefficients to obtain an experiment weight coefficient mapping the experiment classification; determining a detection indicator used by the diagnostic experiment, and searching a mapping relationship table of detection indicators versus indicator weights to obtain an indicator weight mapping the used detection indicator; and according to the obtained contamination value, the experiment weight coefficient and the indicator weight, acquiring a soil ecotoxicity comprehensive score, calculating a ratio of the soil ecotoxicity comprehensive score to an individual level score maximum, and determining a soil ecological harmfulness level of the contaminated site according to the ratio. The application of the method and apparatus provided by the present invention can effectively improve accuracy of assessment of a contaminated site.

Description

technical field [0001] The invention relates to soil ecological technology, in particular to a method and device for optimizing soil ecotoxicity diagnosis results of 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 ex...

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

[0006] In practical applications, since the soil ecosystem is a complex system, different test organisms have different impacts on the soil ecosystem, and at the same time, the sensitivity of the selected detection indicators to the pollutants of concern in the polluted site is also different, making different The soil ecotoxicity diagnosis results obtained by the test organisms and the diagnostic tests for different detection indicators are quite different. In the existing technology, the final soil ecotoxicity diagnosis results are generally obtained by selecting the maximum value or using a balanced weighting method, as pollution The basis for the evaluation of the pollution status of the site makes the accuracy of the evaluation not high, it is easily affected by the tested organisms and the selected detection indicators, and cannot reflect the actual pollution status of the polluted site
