AB  - Soil structure is an important index to evaluate soil quality; however, previous 
      researchers have only paid attention to the effect and economic benefits of soil 
      heavy metal remediation. In this study, microbial-induced carbonate precipitation 
      (MICP) technology was used to remediate soil Pb pollution, and its effect on soil 
      structure was studied by sieving and X-ray computed tomography techniques. The 
      results showed that the leaching amount of heavy metals in soil decreased by 
      76.34% after remediation. Interestingly, due to the addition of organic matter 
      and microorganisms, the soil particle size changed from microaggregates to large 
      aggregates, and the large soil particle size (diameter > 2 mm) increased 
      significantly by 71.43%. The soil porosity increased by 73.78%, which enhanced 
      the soil permeability and increased the soil hydraulic conductivity. Therefore, 
      MICP bioremediation not only remediated soil heavy metal pollution but also 
      promoted the soil aggregation structure, which has important significance for 
      soil remediation and improvement.
