Ammonium-Enhanced Arsenic Mobilization from Aquifer Sediments

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Ammonium-related pathways are important for groundwater arsenic (As) enrichment, especially via microbial Fe(III) reduction coupled with anaerobic ammonium oxidation; however, the key (and microorganisms) underpinning ammonium-induced and their contributions to As mobilization in still unknown. To address this gap, aquifer sediments hosting high from western Hetao Basin were incubated 15N-labeled external organic carbon sources (including glucose, lactate, lactate/acetate). Decreases concentrations positively correlated increases total produced Fe(II) (Fe(II)tot) released As. The molar ratios of Fe(II)tot oxidized ranged 3.1 3.7 all incubations, δ15N values N2 headspace increased ammonium-treated series, suggesting as end product oxidation. addition release by 16.1% 49.6%, which was more pronounced when copresented electron donors. Genome-resolved metagenomic analyses (326 good-quality MAGs) suggested that system required syntrophic metabolic interactions between bacterial archaeal current results highlight significance ammonium-stimulated driving mobilization, is underestimated groundwater.
