Heavy metals (HMs) in aquatic environments are characterized by high toxicity, a propensity for bioaccumulation, and non-degradability, pose significant risks to biological communities. Previous studies of HMs lakes have shown that the physical chemical characteristics lake water may control both migration sediments concentration heavy water. In fact, change changes metal fraction sediment, which controls release HMs. this paper, we investigated effects pH, temperature, salinity levels overlying on Cu Zn Wuliangsuhai Lake surface sediments. The results show lower pH higher temperature could increase from sediment. An led speciation solid fractions Zn, namely increases residual decreases organic matter sulfide, whereas acid-extractable Fe-Mn oxide remained largely same. Increases opposite fractions, sulfide effect solids was much smaller. According ratio secondary phase primary (RSP), acidic, high-temperature, high-salt conditions Zn. Changes greatest influence risk sediments, followed changes.

Ice, water, and sediment represent three interconnected habitats in lake ecosystems, bacteria are crucial for maintaining ecosystem equilibrium elemental cycling across these habitats. However, the differential characteristics driving mechanisms of bacterial community structures ice, sediments seasonally frozen lakes remain unclear. In this study, high-throughput sequencing technology was used to analyze compare structure, function, network characteristics, assembly communities Wuliangsuhai, a typical cold region Inner Mongolia. The results showed that ice water phases had similar diversity composition, with Proteobacteria, Bacteroidota, Actinobacteria, Campilobacterota, Cyanobacteria as dominant phyla. displayed significant differences from Chloroflexi, Firmicutes, Desulfobacterota, Acidobacteriota being Notably, exhibited higher spatial variability their distribution than those sediment. This study also revealed during period, species media were dominated by cooperative relationships. Community primarily influenced stochastic processes, dispersal limitation drift identified two most factors within process. heterogeneous selection played role composition. Furthermore, functions related nitrogen, phosphorus, sulfur, carbon, hydrogen vary among These findings elucidate intrinsic structure changes quality different (ice, sediment) cold-zone freezing offering new insights environmental protection ecological restoration efforts such environments.

Due to the high altitude, unique geographical location, difficult accessibility and low temperature, environmental factors influencing phytoplankton composition have rarely been investigated in Selin Co Lake, which is largest lake Tibetan Plateau. Phytoplankton can indicate aquatic ecosystem conditions, may be sensitive In this study, we main that influence species Lake by analyzing spatial distribution applying statistical analyses. We also compared influential with other lakes around world. The results suggest eleven variables explain about 46.78% of phytoplankton’s composition. DO fluoride were most significant variables, followed arsenic COD, had comparatively smaller more insignificant influences on There five dominant namely, Microcystis sp., Navicula spp., Chlorella vulgaris, Ankistrodesmus falcatus, Westella sp. Some these found tropical lakes, suggesting community could adapt changes. A clear understanding affecting help us make proper water quality protection strategies future climate change scenarios.

Water replenishment is an important measure for maintaining and improving the aquatic environmental quality of lakes. The problems water deterioration shortage can be alleviated by introducing higher quality. However, mechanism in improvement trophic status lakes remains unclear. This study investigated Wuliangsuhai Lake (WLSHL) from 2011 to 2021 collecting seasonal samples conducting laboratory analyses. was found capable significantly lake alleviating eutrophication. It worth noting that single long-term measures have limitations status. whole process divided into three stages according status, namely buffer period, decline stable period. During showed only slight because small amount low proportion higher-quality Yellow River. In with increasing replenishment, River gradually increased, leading most significant degree improvement. increases had little effect on which attributable balance between internal pollutants (lake water-sediment), internal-external water-irrigation return flow + water).

Spring algal blooms in mid–high-latitude lakes are facing serious challenges such as earlier outbreaks, longer duration, and increasing frequency under the dual pressure of climate warming human activities, which threaten health freshwater ecosystems water security. At present, freeze-thaw processes is key to distinguishing spring mid- high-latitude from low-latitude lakes. Based on visualization an analysis literature WOS database during 2007–2023, we clarified driving mechanism process (freeze-thaw, freeze-up, thawing) bloom by describing evolution nutrient migration transformation, temperature, lake transparency dissolved oxygen, physiological characteristics algae between shallow deep We found that complex phosphorus transformation frozen period can better explain spring-algal-bloom phenomenon compared nitrogen. The dominant species also undergo process. On this basis, response future change has been sorted out. general framework “principles analysis, model construction, simulation prediction, assessment management” prevention strategy for dealing with have proposed, would like provide scientific support reference comprehensive control freezing thawing processes.
