摘要:

随着工业化水平的不断提高,人类社会活动范围和规模的不断扩大,一些重金属污染物通过各种形态和渠道进入土壤,由于重金属污染物具有难移除,不易降解,危害大等特点,所以给土壤造成了严重的污染。土壤重金属污染所带来一系列人类健康问题也越来越突出,因此土壤重金属治理研究已刻不容缓。明确土壤中重金属污染物的种类、来源渠道、超标危害,以及污染治理方式、治理机制、优点和不足,对更好的开展土壤重金属防护治理工作能起到促进作用。通过整理土壤重金属污染相关资料,就污染防治问题简单阐述,并对重金属污染治理工作进行初步展望,为相关工作的开展提供参考。

Abstract:

With the increase of the industrialization level, some heavy metal pollutants enter soil through different kinds of forms and channels with the expanding scope and scale of human social activities. Because heavy metal pollutants have features like being difficult to remove and to degrade and very harmful, they could cause serious pollution to soil. Human health problems brought by heavy metal pollution in soil have become more and more prominent, therefore, research on soil heavy metal treatment is extremely urgent. Clarifying the types, sources and excessive hazards of heavy metal pollutants in soil, as well as pollution control methods and mechanisms and their advantages and disadvantages, could play a promoting role in carrying out soil heavy metal control and management. Through literature research, the authors elaborated the problems in the heavy metal pollution control and discussed its development prospect, aiming to provide reference for related scientific research.

Key words: heavy metal pollution, soil, heavy metal treatment, soil remediation, source of heavy metals
