Coal mine area soil heavy metal pollution practical evaluation method

Abstract

The invention relates to the technical field of soil heavy metal pollution evaluation, and discloses a coal mine area soil heavy metal pollution practical evaluation method, being characterized in that the coal mine area soil heavy metal pollution practical evaluation method is high in feasibility, is high in the practical application research value, takes a coal mine area soil heavy metal background value, a soil baseline value, a single factor pollution index and an inner Meiluo comprehensive pollution index in a coal mine area soil environment, and a potential ecological hazard index in a coal mine area soil pollution risk as basic quantification numerical values to divide soil heavy metal element content pollution degree grades, and then determines a practical evaluation method for coal mine area soil heavy metal pollution. The coal mine area soil heavy metal pollution practical evaluation method provides an effective way for evaluating the environmental quality of the heavy metalcontaminated soil in the coal mine area, can describe and evaluate the heavy metal contaminated condition of the soil more accurately, can improve the effectiveness and accuracy of evaluating the heavy metal contaminated environment of the soil in the coal mine area, and is suitable for application and popularization in research of the heavy metal contaminated soil environment in the coal mine area.

Description

technical field [0001] The invention relates to the technical field of evaluating soil heavy metal pollution, in particular to a practical evaluation method for soil heavy metal pollution in coal mining areas. Background technique [0002] Soil is an important natural resource of the country, and it is also the material basis for the survival and development of human beings. With the increase of population, the development of mining industry and the reduction of cultivated land area per capita, it is particularly important to rationally utilize, manage and restore soil resources in mining areas. my country's energy structure is dominated by coal, which accounts for about 70% of primary energy consumption, and will not change in recent decades. While coal has made great contributions to my country's economic development, it has also seriously affected the soil environment in mining areas. For example, surface subsidence in coal mining areas; accumulation of solid waste (coa...
