AB  - As one of the most toxic heavy elements, humans are mainly exposed to cadmium 
      (Cd) via daily diets and smoking. Calcite can be used as an amendment directly or 
      precipitated in situ based on microbial-induced carbonate precipitation (MICP) 
      technology to immobilize Cd in soil with potential release of Cd due to calcite 
      dissolution. Therefore, we converted microbial-induced calcite to less soluble 
      hydroxyapatite and investigated the phase and morphology evolutions of the 
      solids, as well as the immobilized efficiency, distribution and release of Cd. 
      The results showed that the conversion of calcite to hydroxyapatite enhanced Cd 
      removal efficiency up to 1.67% and 33.14% compared to the MICP process and 
      adsorption by calcite, respectively. Accordingly, the released Cd decreased up to 
      94.10% and 99.96%, respectively. Our findings demonstrated that the conversion of 
      calcite to hydroxyapatite might control the environmental behavior of heavy 
      metals like Cd and can potentially be applied for soil remediation.
