Research progress on passivation remediation of soil heavy metal pollution
How to effectively control and repair heavy metal contaminated soil,and ensure food security has become a research hotpot in the field of agriculture and environmental ecology.Under the background of the prominent contradiction between the shortage of high-quality arable land resources and the demand for food production,in-situ passivation technology is considered to be a practical and feasible restoration technology that can ensure the safe production of crops.This paper summarized the current research status of the passivation remediation technology of heavy metal contaminated soil at the aspects of type of passivation materials and the existing problems of passivation remediation technology utilization.Meanwhile,the factors that affected the remediation effects were also analyzed,and suggestions for the future research on the passivation remediation of heavy metal contaminated soil were put forward.These results could provide theoretical guidance to utilize the passivation materials and passivation remediation technology scientifically,reasonably and efficiently,and realize the safety utilization of contaminated farmland.
