Abstract

The invention discloses a method for predicting and warning a soil heavy metal pollution area. The method comprises: collecting and preprocessing an original soil sample; carrying out sample separation and detection; carrying out data processing and analysis; and building a prediction model. According to the method disclosed by the invention, the soil-attached plants are received into the heavy metal detection range, so that the detection contents become comprehensive and accurate; and on the basis of combination of the heavy metal effective state theory with the GIS visualization technology,the prediction result has the great practical significance, so that the theoretical basis and scientific basis are provided for ecological risk evaluation, control, treatment, and repairing of the heavy metal pollution on soil.

Description

technical field [0001] The invention relates to the field of prevention and control of heavy metal pollution, in particular to a method for predicting soil effective heavy metal pollution. Background technique [0002] At present, heavy metal pollution has become a worldwide environmental problem. The sources of heavy metal pollutants (such as Mn, Pb, Cd, Cr, Cu, Zn, etc.) include the extensive use of various common metals in various industries and the waste of them. Untreated burial, 90% of the heavy metals eventually enter the soil. Once the soil is polluted by heavy metals, it is difficult to repair and treat, and it will also cause secondary pollution of water and air environmental quality. Some industrially developed countries have paid a heavy price for this. At the cost, the cultivated land area polluted by heavy metals such as cadmium, arsenic, chromium and lead in China is nearly 20 million hectares, accounting for about 1 / 5 of the total cultivated land area, and heav...
