土壤pH对镉形态影响的研究进展

镉作为生物体的一种非必需元素,因其在土壤中的强迁移性和对人体的高度危害性而被列为国家重点关注的五大毒性重金属元素之一。镉在土壤中的迁移性及毒性与其形态密切相关,而土壤pH是影响镉形态的最重要因素之一,因此,本文综述了土壤镉形态的分析方法,阐述了土壤pH对镉形态的影响,并深入探讨了土壤pH对镉形态的影响机制,最后对今后的研究方向进行了展望,以期为镉污染土壤的修复与治理提供参考。

Advances in Effects of Soil pH on Cadmium Form

Cadmium (Cd), a non-essential element of organisms, has been listed as one of the five major toxic heavy metal elements because of its strong mobility in soil and high risk to human body. The migration and toxicity of Cd in soil are closely related to its existence, and soil pH is one of the most important factors affecting the existence of Cd. Therefore, in this paper, the analysis methods of soil Cd morphology were reviewed, and effects of pH on Cd and the mechanism were discussed. Finally, the future research directions are prospected, which could provide references for the treatment and remediation of cadmium contaminated soil.
