Unraveling the Coupled Dynamics between DOM Transformation and Arsenic Mobilization in Aquifer Systems during Microbial Sulfate Reduction: Evidence from Sediment Incubation Experiment

Water, Journal Year: 2024, Volume and Issue: 16(9), P. 1266 - 1266

Published: April 28, 2024

Geogenic arsenic (As)-rich groundwater poses a significant environmental challenge worldwide, yet our understanding of the interplay between dissolved organic matter (DOM) transformation and mobilization during microbial sulfate reduction remains limited. This study involved microcosm experiments using As-rich aquifer sediments from Singe Tsangpo River basin (STR) Jianghan Plain (JHP), respectively. The findings revealed that remarkably increased in both STR JHP compared to unamended sediments. Moreover, As coincided with increases fluorescence intensity two humic-like substances, C2 C3 (R = 0.87/0.87 R 0.73/0.66 sediments, respectively; p < 0.05), suggesting competitive desorption DOM incubation. transformations molecular characteristics showed CHOS low-O/C-value intensities corresponding enhancement possible occurrence methanogenesis processes, which suggests substantial bioproduction contribution components is conducive reduction. present results thus provide new insights into co-evolution alluvial systems under strong conditions.
