Vanadium(V) is a highly toxic multivalent, redox-sensitive element. It is widely distributed in the environment and employed in various industrial applications. Interactions between V and (micro)organisms have recently garnered considerable attention. This Review discusses the biogeochemical cycling of V and its corresponding bioremediation strategies. Anthropogenic activities have resulted in elevated environmental V concentrations compared to natural emissions. The global distributions of V in the atmosphere, soils, water bodies, and sediments are outlined here, with notable prevalence in Europe. Soluble V(V) predominantly exists in the environment and exhibits high mobility and chemical reactivity. The transport of V within environmental media and across food chains is also discussed. Microbially mediated V transformation is evaluated to shed light on the primary mechanisms underlying microbial V(V) reduction, namely electron transfer and enzymatic catalysis. Additionally, this Review highlights bioremediation strategies by exploring their geochemical influences and technical implementation methods. The identified knowledge gaps include the particulate speciation of V and its associated environmental behaviors as well as the biogeochemical processes of V in marine environments. Finally, challenges for future research are reported, including the screening of V hyperaccumulators and V(V)-reducing microbes and field tests for bioremediation approaches.

环境中的钒:生物地球化学和生物修复

钒 (V) 是一种剧毒多价氧化还原敏感元素。它广泛分布在环境中并应用于各种工业应用。V 和(微生物)生物之间的相互作用最近引起了相当多的关注。本综述讨论了 V 的生物地球化学循环及其相应的生物修复策略。与自然排放相比,人为活动导致环境 V 浓度升高。这里概述了 V 在大气、土壤、水体和沉积物中的全球分布,其中在欧洲尤为普遍。可溶性 V(V) 主要存在于环境中,具有高迁移率和化学反应活性。还讨论了 V 在环境介质内和跨食物链的运输。对微生物介导的 V 转化进行评估,以揭示微生物 V(V) 还原的主要机制,即电子转移和酶催化。此外,本综述通过探索其地球化学影响和技术实施方法来强调生物修复策略。已确定的知识差距包括 V 的颗粒形态及其相关的环境行为以及 V 在海洋环境中的生物地球化学过程。最后,报告了未来研究面临的挑战,包括 V 超富集植物和 V(V) 还原微生物的筛选以及生物修复方法的现场测试。
