Throughout the literature, word "heavy metal" (HM) has been utilized to describe soil contamination; in this context, we characterize it as those elements with a density greater than 5 g per cubic centimeter. Contamination is one of major global health concerns, especially China. China's rapid urbanization over past decades caused widespread urban water, air, and degradation. This study provides complete assessment contamination by heavy metals mining smelting regions. The (HMs) includes an examination their potential adverse impacts, origins, strategies for remediation contaminated metals. presence can be linked both natural anthropogenic processes. Studies have demonstrated that soils present risks individuals. Children are more vulnerable effects metal pollution adults. results highlight significance operations Soil poses significant carcinogenic non-carcinogenic, particularly children individuals living heavily polluted areas. Implementing physical, chemical, biological techniques most productive approach addressing metal-contaminated soil. Among these methods, phytoremediation emerged advantageous option due its cost-effectiveness environmentally favorable characteristics. Monitoring utmost importance facilitate implementation improved management soils.

Recently, the ability of microbial-induced calcium carbonate precipitation (MICP) to remediate heavy metals has been widely explored. Sporosarcina pasteurii was selected metal-contaminated solution and aged refuse, exploring feasibility bioremediation analyzing changes in metal forms before after bioremediation, as well mechanism remediation. The results showed that achieved remediation rates 95%, 84%, 97%, 98% for Cd, Pb, Zn, Cr (III) contaminated solution, respectively. It also 74%, 62% exchangeable Zn content almost zero. with form carbonate-bounded refuse decreased while iron-manganese oxide binding residual increased. Simultaneously, presence Fe Al components produced during MICP process, jointly promotes transformation into more stable forms.
