ABSTRACT

Nickel is abundant in the earth's crust and is as one of the eight major elements that cause soil pollution in the soil in China. Recently, nickel pollution has become an important environmental problem affecting China's economic and social development. In order to practice the scientific concept of “lucid waters and lush mountains are invaluable assets” and understand the pollution degree of nickel from the source, scientific methods have been adopted to improve the pollution in the soils. This study summarizes pollution status of nickel both domestic and international, and takes a contaminated plot in the Longwan District in Wenzhou City of Zhejiang Province as an example to further analyze the source of nickel pollution in the soil, which is of great significance for finding suitable remediation methods. Various remediation technologies for nickel pollution involve physical and chemical remediation technology, plant and microbial remediation technology, particularly, passivator remediation technology with great application potential and commercial prospects is used as a key way for nickel pollution control from soils.
