土壤污染作为一个制约人类社会可持续发展的基本问题正受到日益广泛的关注。造成土壤污染的原因主要有过量使用农药和化肥、各类污水、污泥及固体废弃物的不当处理、有害物质的事故性排放及各类污染物在土壤中的积累等。土壤污染对地下水及地表水造成次生污染,通过饮用水或土壤—植物系统经由食物链进入人体而危及人类健康。 
 
近年来,欧美国家先后投入大量人力物力进行被污染土壤的修复和治理。荷兰政府在20世纪80年代就投入15亿美元进行土壤的修复技术研究和应用试验,德国政府在1995年投资60多亿美元进行土壤修复,美国政府近期也投入100多亿美元用于土壤修复技术开发研究。污染土壤的修复技术研究成为当前环境保护工程科学和技术研究的一个新热点。
