Abstract

Abstract

For the existing soil pollution risk assessment methods are not closely related to soil and agricultural products pollution, and have poor applicability in different scenarios, a collaborative assessment method of heavy metal pollution risk in cultivated land based on multi-factor fusion was proposed, and the effectiveness of the method was verified by taking the risk assessment of heavy metal pollution in cultivated land soil in a county in southern China as an example. Based on soil environmental quality standards, soil background values, toxicity, and physical and chemical properties of heavy metal elements, the soil load capacity weight index was proposed. The heavy metal elements with the greatest ecological hazard in composite pollution were screened out, and the regional soil pollution risk under different scenarios was evaluated by the comprehensive evaluation index, and then the risk levels were determined by combining the pollution of agricultural products to build a collaborative risk assessment framework. The results showed that the soil pollution risk in the study area was divided into four levels, the negligible risk area accounted for 8.23% of the total cultivated land area, the low risk accounted for 17.45%, the medium risk and high risk areas accounted for 57.18% and 17.14%, respectively, the dominant heavy metal elements of soil pollution were Cd and Hg, and the medium and high pollution risk areas were mainly distributed in the central and eastern parts of the study area, and agricultural products had strong cadmium enrichment capacity. Compared with the geo-accumulation index method and the potential ecological hazard index method, the comprehensive evaluation index method proposed in this paper can automatically evaluate the risk of multi-element composite pollution, and effectively avoid the problem of unreasonable evaluation results caused by improper setting of the weight of each evaluation index.
