Abstract:

Central-south China is distinguished by the considerable numbers and areas of non-ferrous metal smelting sites that have polluted the soils both within and surrounding the sites. This brings serious risks to the local environment and needs to be controlled urgently. To explore the pollution characteristics of the smelting sites and the surrounding soil in central-south China and the main effective stabilization and remediation technologies, we summarized the distribution of nonferrous metal smelting sites in Hunan, Hubei, Jiangxi and Anhui, and their pollution status. The pollution characteristics included large pollution area, mainly compound pollution, diversified pollution ways, different pollution levels and high heavy metal activity. The advances of stabilized materials used in remediation were expounded from two aspects: stabilization mechanism and material type. Finally, we discussed future research on the development of composite stabilization materials with high-performance, sustainability, wide adaptability and environmental value, aiming to provide support for the stabilized remediation of soil heavy metal pollution in nonferrous metal smelting sites and surrounding soil in central-south China.

Key words: central-south China, smelting, site, soil heavy metal, stabilization, remediation
