由于潜在有毒元素对人类健康和环境质量构成重大威胁，全球对潜在有毒元素的关注正在稳步增加。这需要立即、有效和高效的补救解决方案。蚯蚓是“生态系统工程师”，可以改变和改善土壤健康，提高植物生产力。近年来，人们对蚯蚓单独或与其他土壤生物和/或土壤改进剂联合修复pte污染土壤的潜力给予了相当大的关注。然而，迄今为止，利用蚯蚓修复pte污染土壤（即蚯蚓修复）尚未得到彻底的审查。因此，本综述讨论了蚯蚓作为pte污染土壤生物修复和减轻环境和人类健康风险的潜在候选者的适用性，并提供了全面的见解。具体来说，我们回顾和讨论了：i) pte污染土壤中蚯蚓的发生和丰度；ii) pte对受污染土壤中蚯蚓群落的影响;iii)影响蚯蚓pte积累和消除的因素；iv)蚯蚓改良土壤中pte的动态和命运。技术可行性、知识差距和实际挑战已经制定出来并进行了批判性讨论。因此，本综述可为pte污染土壤的生物修复提供参考和指导，也有助于开发创新和适用的解决方案来控制pte的生物利用度，以修复污染土壤，减轻环境和人类风险。
Global concerns towards potentially toxic elements (PTEs) are steadily increasing due to the significant threats that PTEs pose to human health and environmental quality. This calls for immediate, effective and efficient remediation solutions. Earthworms, the 'ecosystem engineers', can modify and improve soil health and enhance plant productivity. Recently, considerable attention has been paid to the potential of earthworms, alone or combined with other soil organisms and/or soil amendments, to remediate PTEs contaminated soils. However, the use of earthworms in the remediation of PTEs contaminated soil (i.e., vermiremediation) has not been thoroughly reviewed to date. Therefore, this review discusses and provides comprehensive insights into the suitability of earthworms as potential candidates for bioremediation of PTEs contaminated soils and mitigating environmental and human health risks. Specifically, we reviewed and discussed: i) the occurrence and abundance of earthworms in PTEs contaminated soils; ii) the influence of PTEs on earthworm communities in contaminated soils; iii) factors affecting earthworm PTEs accumulation and elimination, and iv) the dynamics and fate of PTEs in earthworm amended soils. The technical feasibility, knowledge gaps, and practical challenges have been worked out and critically discussed. Therefore, this review could provide a reference and guidance for bio-restoration of PTEs contaminated soils and shall also help developing innovative and applicable solutions for controlling PTEs bioavailability for the remediation of contaminated soils and the mitigation of the environment and human risks.
