Abstract Mercury (Hg) and methylmercury (MeHg) are highly neurotoxic substances, reservoirs play a critical role in Hg storage while providing geochemical environments conducive to MeHg production. However, the mechanisms of transport methylation during reservoir regulation remain poorly understood. This study investigates spatial distribution sediment both horizontal vertical profiles within Nuozhadu Reservoir, located upper Mekong River. Using diffusive gradients thin films (DGT) technique, we observed that concentrations initially increased then slightly decreased from tail dam front reservoir. trend is primarily attributed fine particles influenced by interception. production was transport, but hydraulic conditions driving accumulation emerged as dominant source MeHg. Furthermore, fluctuations DGT-Hg DGT-MeHg values were noted, likely caused periodic operations. Our findings indicate sediments release into overlying water, establishing significant pollution reservoirs. enhances our understanding processes under influence regulation.

Periods of thermal stratification in deep dams can result increased liberation ammonia and phosphates at the sediment-water interface, which cause nutrient enrichment downstream river section. We studied recovery gradient a thermally altered, regulated, unpolluted stream its dependency on main environmental variables. Macroinvertebrate assemblages were assessed spring-summer autumn periods, three sampling sites 1.25 km reach, from dam, for 4 years (2019-2022). Water samples collected all riverine one site dam. Nutrients measured hydrological alteration indices calculated longitudinal survey. aimed to unravel variables linked dam-induced hydro-morphological pressure affecting macroinvertebrate communities. Complex interactions between nutrients physical parameters identified as responsible observed trends. The analysis revealed natural-born hypolimnetic most contributing parameter biomonitoring metrics reflecting status macroinvertebrates. Ammonia enters system mainly during dam periods (spring-summer) result, communities had highest rates autumn. In this season achieve good ecological even near 25 m below wall if concentrations are low. Therefore, seasonal fluctuations such dissolved oxygen temperature hypolimnion invertebrate
