In China，the widespread pollution of soils with metals and metalloids，polymetallic composite pollution，especially soil contaminated by As and heavy metals is difficult to govern.Polymetallic pollutants accumulated in soil seriously threaten soil health，agricultural product safety and human settlements.Therefore，the remediation of multi-metal contaminated soil is an important proposition for the risk management of contaminated soils.Solidification/Stabilization is the most widely used soil remediation technology in China.This remediation method is based on the reduction of heavy metal bioavailability and mobility via the addition of amendments，thereby effectively blocking the exposure pathway of polymetallic pollutants.The stabilization mechanisms of As and heavy metals，and to summarize emerging materials for metal immobilization.The main immobilization mechanisms involved in the immobilization process are surface complexation and precipitation.Amendments rich in iron and calcium have proven to be effective for the remediation of As and heavy metal contaminated soils.It has been observed that the effectiveness of soil remediation depends on the type of amendments，pollutants，the application rate，and soil characteristics such as cation exchange capacity，redox potential，organic matter content and pH.This paper summarizes recent advances on the research of the biomass-derived engineering composites (e.g.，biochar composites)，industrial waste-derived materials，natural minerals and other green materials.Future research on long-term effectiveness of these novel material-based immobilization should be conducted.More field trials evaluating the stability of the amendments in the treated soils and their efficiency in the long run need to be highlighted.
