铜污染土壤的生物修复研究进展

Progress in bioremediation of copper-contaminated soils

摘要:

随着工业化与农业化进程的加快，土壤重金属污染问题日益突出。铜 (Cu) 既是生命体生长发育的必需微量元素，也是重金属污染物之一。土壤中过量的Cu不仅会对植物产生毒害，而且能够通过食物链的富集作用，对人类健康造成严重威胁。生物修复技术作为治理重金属污染土壤的一种新型技术受到广泛关注。文中对生物修复的主要技术如植物修复、微生物修复、植物-微生物联合修复、动物修复等在治理Cu污染土壤方面的研究进展进行综述，以期为重金属污染土壤有效治理和可持续农业的发展提供理论依据。

Abstract:

With the acceleration of industrialization and agriculture, soil heavy metal pollution has become increasingly serious. Copper, though an essential trace element for the growth and development of living organisms, is one of the main heavy metal pollutants. Excess copper in soil is toxic to plants and threatens human health via food chain. Bioremediation has received extensive attention as a novel technology for heavy-metal-contaminated soils. Here, we review the development of bioremediation technologies, including phytoremediation, microbial remediation, plant-microbe combined remediation, and animal remediation, for copper-contaminated soils, in order to provide a theoretical basis for the effective management of heavy-metal-contaminated soils and the sustainable development of agriculture.
