摘要
当前,我国土壤重金属污染较为严重,特别是镉污染因其毒性大、稳定、难去除等特点受到人们的广泛关注。在分析土壤镉污染现状、来源及危害的基础上,系统介绍了目前镉污染的物理修复、化学修复、生物修复等主要修复措施,并提出了加强镉污染源头控制、强化低累积农作物品种的筛选选育及修复技术的研究、完善相关法律法规等对策建议。
At present, heavy metal pollution in our country is serious, especially cadmium pollution because of itshigh toxicity, stability anddifficulty in removing. Based on theanalysis of the present situation, sources and hazards ofcadmium pollution in the soil, this paper systematically introduces the physical, chemical and biological remediationmeasures for cadmium pollution. Some suggestions were put forward to strengthen the source control of cadmiumpollution, the selection and breeding of low-cumulative crop varieties, and to improve relevant laws and regulations.
