Summary: Bacteria have important roles in biogeochemical cycling, self-purification, and food web dynamics in fresh-water ecosystems. However, the comparison between the impacts of conventional and emerging pollutants on bacteria in surface water and sediment is not well-understood. In this study, the spatial distributions of pollutants, pharmaceuticals, and bacterial communities in Taihu Lake, China were investigated. The results indicate that pharmaceuticals were more concentrated in the impacted zone and had close positive relationships with bacterial phyla in the water. The ratio of Firmicutes to Proteobacteria in surface water is suggested as a potential bioindicator for evaluating pharmaceutical contamination and bacterial resistance. In the sediment, phosphorus pollutants were associated with specific bacterial genera, suggesting a potential risk of phosphorus release from sediment to water.

Summary: This study evaluated the potential release risks of nitrogen and phosphorus from sediments in freshwater reservoirs in Beihai City, southern China, and found that sediment adsorption properties, redox properties, and microbial-mediated properties were the main controlling factors for nutrient release risks. These factors varied with temperature.

Summary: Previous studies have shown that e-SOx can regulate the release of phosphorus (P) in brackish and marine sediments. Cable bacteria have also been found in freshwater sediments, and they may play a role in the regulation of P availability in eutrophied freshwater streams. The activity of cable bacteria can lead to the dissolution of metal oxide layers and the release of Fe2+ and Mn2+. Overall, cable bacteria may have a significant impact on countering eutrophication in freshwater systems.

Summary: This study examines the nutrient dynamics in Flathead Lake over a period of 38 years. Despite low nutrient levels, the lake maintained high nitrogen to phosphorus ratios. This stoichiometric imbalance led to phosphorus limitation in phytoplankton growth and affected the nutrient cycling in the entire ecosystem.

Summary: This study analyzed the changes in physicochemical properties of suspended sediment particles (SSPs) in Poyang Lake using SEM-EDS. The SSPs consisted primarily of clay and chalk, with varying particle size distributions. The results revealed the correlation between water flow velocity, suspended-solid concentration, and SSP properties, and estimated the endogenous phosphorus load in different zones of the lake.

Summary: Approximately one-third of the year, Daihai Lake experiences freezing conditions, affecting the quality of lake water. The freezing process causes migration of nutrients to the subglacial water, with NO3--N and POa--P being the predominant constituents. Sediment in the lake acts as a source of POa--P and NO3--N while absorbing NH4+-N. Soluble reactive P (SRP) and NO3--N flux contribute to P and N in the overlying water, while a significant portion of NH4+-N flux is absorbed by sediment. The presence of soluble and active P in the ice sheet plays a crucial role in sediment release of SRP and NH4+-N.

Summary: China has successfully improved the water quality of rivers, but lakes still face challenges in terms of water quality. Achieving the United Nations Sustainable Development Goals requires controlling external nutrient loads and internal loads in lakes, utilizing a combination of nature-based solutions and engineered systems.

Summary: Reservoirs, commonly found along rivers, provide a multitude of ecosystem services such as sequestering sediments and nutrients. Studies need to focus on understanding how reservoirs function individually and as part of sequences within large rivers and watersheds. Further research is needed to explore the impacts of reservoirs on nutrient deposition and their interactions within watershed-sediment-transport systems.

Summary: Limnologists have made significant progress in understanding the indicators of phosphorus-eutrophy in surface waters, focusing on biotic variables such as macro-invertebrates, fish, zooplankton, benthic algae, and diatoms. The use of alkaline phosphatase (ALP) as a proxy for P-deficiency and benthic anoxia/hypoxia-driven feedbacks shows promise as a cost-effective and reliable tool for assessing changes in nutrient stoichiometry and trophic status.

Summary: The study investigated the transfer of eight elements in a boreal freshwater food chain and found that sediment is an important source of uptake for most elements. The results suggest that assumptions of linear transfer may not be valid for elements into fish, highlighting the need for further research to develop radioecological models.

Summary: This study investigates the impact of climate-induced changes in vegetation on hydrology and environment in the Jialing River Basin. The results show that climate change will cause increased runoff and nitrogen losses, and decreased sediment discharge and phosphorus losses in the basin. The changes in vegetation, predicted to be promoted by climate change, will have significant effects on the basin. The models used in this study provide useful information for formulating management measures.

Summary: This study found that freshwater mussels have an impact on microbial community structure and function in stream sediment, and this impact is influenced by nutrient concentrations. Mussels can change the composition of sediment microbial communities, and the changes vary under different nutrient conditions. Mussels may promote functional redundancy in sediment microbial communities and control biogeochemical processes under changing nutrient conditions.

Summary: This study found that the combination of bioturbation and biofilm function (SCB) was more effective in removing total nitrogen than using either bioturbation or biofilm alone. Bioturbation promoted nitrogen release from sediments to the overlying water, while biofilm enhanced the conversion and removal of nitrogen, resulting in the lowest concentration of total nitrogen in the overlying water in SCB treatment.

Summary: The use of oxygen-loaded lanthanum modified zeolites (LOZ) can effectively absorb phosphorus and nitrogen from lake sediments, while improving dissolved oxygen levels and reducing the release of these nutrients into the overlying water. This approach provides a quick, efficient, and sustainable remediation method for polluted water systems.

Summary: This study found that climate, especially the average minimum temperature of the coldest month, is the main driver of ecosystem carbon, nitrogen, and phosphorus residence times. In cold regions, residence times of carbon and phosphorus decrease with increasing temperature, while in warm regions, they increase with temperature.

Summary: Beijing parks have high levels of lead in the soil, posing a potential threat to human health, especially children. Factors such as geographical location, soil properties, and chemical forms affect the bioaccessibility of lead in the soil. The PBET method and DIFS model can provide reliable references for park managers to manage the health risks associated with lead pollution.

Summary: This study evaluated the spatial and temporal variations of molybdenum in the downstream water body of a Mo mine during three hydrologic periods. Results showed that the redox potential and dissolved oxygen increased in the dry season, while temperature, conductivity, and total dissolved solids decreased in the wet season. The total Mo concentration was higher in the wet and medium seasons, but the percentage dissolved Mo was lowest in the wet season.

Summary: Water pollution is a major global environmental problem, especially in developing countries. China has made remarkable achievements in water pollution control in the past twenty years, with wastewater collection and treatment capacity reaching a level similar to developed countries. Although the environmental quality of surface water has continuously improved, water pollution problems persist in the eastern river basins alongside remarkable economic progress. Rapid economic growth, rather than population growth, is the limiting factor for water pollution control in China. Further efforts are needed to enhance wastewater collection and treatment capacity and bridge the gap between effluent discharge limits and surface water quality standards. China's progress in water pollution control provides valuable insights for other developing countries.
