Abstract: |
Nickel is one of the eight heavy metals that cause soil pollution in China. The yield and quality of crops are affected by the excessive nickel concentration in farmland soil, which cause a serious threat to human health. This present paper provides a review not only on the pollution status and sources of nickel in farmland soils at home and abroad in recent years and its influence on farmland ecosystem (plants, microorganisms and animals), but also various remediation technology for nickel-contaminated soil including physical/chemical remediation technology, microbial remediation techniques, phytoremediation techniques and agro-remediation techniques. At the same time, the nickel-hyperaccumulators discovered so far are introduced, which provide plant species for the research and development of plant extraction technology for nickel-contaminated soil. Finally, it is proposed that several aspects need to be strengthened for remediation of nickel-contaminated soil. |
