Accumulation of Heavy Metal Pollutants in Soil: Sources and Treatment Methods

doi:10.11924/j.issn.1000-6850.casb2021-0303

Abstract

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
