Collaborating iron and manganese for enhancing stability of natural arsenic sinks in groundwater: Current knowledge and future perspectives
Arsenic (As)-rich groundwater poses a serious threat to human life and public environmental safety. In groundwater environments, iron–manganese minerals (FeMn minerals) are widely distributed and have outstanding adsorption and oxidation abilities for many toxic metal ions, making them important heavy metal scavengers. Exploring the application of Nature-based Solutions (NBS) to enhance the natural remediation of As-rich groundwater mediated by the mineralization of Fe and Mn is of great significance for promoting the stability of natural As reservoirs in groundwater. In this work, the effects of FeMn minerals and their related functional microorganisms on the migration and transformation of As in groundwater were reviewed, the interaction between components of FeMn minerals mediated by functional microorganisms on As immobilization process was revealed, the synergistic effect of Fe and Mn mineralization on the stabilization of As reservoir in groundwater was emphasized, and the potential biogeochemical cycles of Fe, Mn, and As mediated by functional microorganisms were analyzed. Based on bibliometric research, it is emphasized that FeMn minerals have a broad prospect in the field of treatment and remediation of As-rich groundwater, and the future prospects of enhancing the synergistic remediation of As-rich groundwater through Fe and Mn mineralization mediated by mixed microbial communities were proposed. In addition, in practical applications, the in-situ fixation of As in groundwater by FeMn minerals still faces technical challenges such as inhibiting the aggregation of As-fixing minerals and strengthening their durability. The results can provide new insights for a comprehensive and in-depth understanding of the synergistic enhancement for As reservoir stability in groundwater by Fe and Mn, as well as the natural remediation and scientific regulation of As-rich groundwater mediated by Fe and Mn mineralization.
期刊介绍:
Chemical Geology is an international journal that publishes original research papers on isotopic and elemental geochemistry, geochronology and cosmochemistry.
The Journal focuses on chemical processes in igneous, metamorphic, and sedimentary petrology, low- and high-temperature aqueous solutions, biogeochemistry, the environment and cosmochemistry.
Papers that are field, experimentally, or computationally based are appropriate if they are of broad international interest. The Journal generally does not publish papers that are primarily of regional or local interest, or which are primarily focused on remediation and applied geochemistry.
The Journal also welcomes innovative papers dealing with significant analytical advances that are of wide interest in the community and extend significantly beyond the scope of what would be included in the methods section of a standard research paper.
