土壤锑污染及其修复技术研究进展

Research Progress on Soil Antimony Pollution and Its Remediation Technology

锑是一种具有潜在毒性和致癌性的元素,人类的活动造成土壤中锑污染日益严重,锑污染问题已引起了各国学者的广泛关注。为了解锑污染土壤研究的进展,文章在对国内外土壤锑污染研究现状及危害基础上,重点对锑污染土壤的修复技术进行概述,主要包括:物理/化学修复技术、生物修复技术、农业生态修复技术、联合修复技术等,以期寻找更高效、更绿色的关于锑治理和修复措施提供参考;对比研究发现,土壤淋洗、固化/稳定化、植物以及微生物修复技术具有技术实施较易、修复成本低,应用价值广的特点,可为中国锑污染修复提供良好技术支撑。

Antimony is a potentially toxic and carcinogenic element, and the soil contamination induced by human activities is becoming more and more serious. The problem of antimony pollution has attracted wide attentions. In order to understand the progress of research on antimony contaminated soil, based on the current research situation and hazards of soil antimony pollution all around the world, this paper focused on the recovery technology of antimony contaminated soil, including physical/chemical remediation, bioremediation, agricultural ecological restoration technology, and joint repairing technology. The goal of this study was to search efficient and environmental friendly ways for recovering of antimony pollution, and it was found that soil leaching, solidification/stabilization, phytoremediation and microbial remediation have great potentials to effectively alleviate antimony pollution in China, due to their easy technical implementation, low cost, and wide application value.
