Amidst the increasing significance of innovative solutions for bioremediation of heavy metal removal, this paper offers a thorough bibliometric analysis of microbial-induced carbonate precipitation (MICP) for heavy metal removal, as a promising technology to tackle this urgent environmental issue. This study focused on articles published from 1999 to 2022 in the Scopus database. It assesses trends, participation, and key players within the MICP for heavy metal sequestration. Among the 930 identified articles, 74 countries participated in the field, with China being the most productive. Varenyam Achal, the Chinese Academy of Sciences, and Chemosphere are leaders in the research landscape. Using VOSviewer and R-Studio, keyword hotspots like "MICP", "urease", and "heavy metals" underscore the interdisciplinary nature of MICP research and its focus on addressing a wide array of environmental and soil-related challenges. VOSviewer emphasises essential terms like "calcium carbonate crystal", while R-Studio highlights ongoing themes such as "soil" and "organic" aspects. These analyses further showcase the interdisciplinary nature of MICP research, addressing a wide range of environmental challenges and indicating evolving trends in the field. This review also discusses the literature concerning the potential of MICP to immobilise contaminants, the evolution of the research outcome in the last two decades, MICP treatment techniques for heavy metal removal, and critical challenges when scaling from laboratory to field. Readers will find this analysis beneficial in gaining valuable insights into the evolving field and providing a solid foundation for future research and practical implementation.
在寻求生物修复重金属去除的创新解决方案的重要性日益增加的背景下，本文对微生物诱导碳酸钙沉淀（MICP）去除重金属这一有前途的技术进行了全面的文献计量分析，以应对这一紧迫的环境问题。本研究聚焦于 1999 年至 2022 年期间在 Scopus 数据库中发表的文章。它评估了 MICP 去除重金属固存领域的趋势、参与情况和关键参与者。在 930 篇已确定的文章中，有 74 个国家参与了该领域的研究，其中中国的参与度最高。Achal Varenyam、中国科学院和《Chemosphere》是该研究领域的领导者。使用 VOSviewer 和 R-Studio，可以发现“MICP”、“脲酶”和“重金属”等关键词热点，强调了 MICP 研究的跨学科性质及其解决广泛的环境和土壤相关挑战的重点。VOSviewer 强调了“碳酸钙晶体”等重要术语，而 R-Studio 则突出了“土壤”和“有机”等方面的持续主题。这些分析进一步展示了 MICP 研究的跨学科性质，解决了广泛的环境挑战，并表明了该领域的发展趋势。本综述还讨论了 MICP 固定污染物的潜力的文献，过去二十年研究成果的演变，MICP 去除重金属的处理技术，以及从实验室到现场的规模扩大时面临的关键挑战。读者将发现这项分析有助于深入了解不断发展的领域，并为未来的研究和实际应用提供坚实的基础。
