摘要：镉是一种有毒重金属,易被动植物吸收,进而对人类产生严重的危害。随着工业和农业的发展,排入到环境中的镉造成的土壤污染日益成为一个严重威胁着生态环境和人类健康的问题。镉污染土壤的治理修复是当前环境科学领域的研究热点和难点之一,受到国内外研究人员的高度重视。详细介绍了目前应用于镉污染土壤的修复技术:物理修复、化学修复、生物修复等,分析了不同修复技术的优缺点、应用范围及修复机制等。最后对未来土壤镉修复技术的发展趋势进行了展望。
Cadmium is a toxic heavy metal,which can lie absorbed by animals or plants and causes various problems.Due to the increased cadmium discharged by industrial and agricultural production,cadmium causer!soil contamination has become a serious problem threatening ecological safety and human health.Studies on remediation of Cd-contaminated soil have become research focus of scientists around the world,in spite of its difficulties.In this review,a summary of remediation techniques applied to cadmium-contaminated soil including physical remediation,chemical remediation and bioremediation has been presented,and mechanisms,advantages and disadvantages have been reviewed as well.At last,based on the features of different remediation strategies,suggestion s and outlook were proposed aiming to achieve improved remediation of Cd-contaminated soil in the future.
