More and more scholars tend to remediate soil heavy metals without affecting the normal agricultural production. By analyzing the mechanism of action of organic materials to remediate Pb pollution in soil,the effect of different organic materials on the passivation of available Pb in soil was summarized,and the prospect was proposed for the future application of organic materials,in order to provide reference for the remediation of Pb and other heavy metals by organic materials.展开更多
