Summary: This paper investigates the release of heavy metals into overlying water under hydrodynamic conditions in lakes. Experimental results show that the concentration of heavy metals is closely related to the concentration of total suspended solids and is influenced by flow velocity. A numerical model based on lattice Boltzmann method is established, and it outperforms traditional simulation models in terms of accuracy. This research contributes to the prediction of lake environments and provides a theoretical basis for heavy metal treatment in reservoirs.

Summary: The study investigated the pollution status of heavy metals in the sediment around Taihu Lake in China, showing that some heavy metals exceeded probable effect levels. Overall, the heavy metals were slightly enriched and indicated moderate to heavy pollution. Cd was identified as the most serious pollutant based on various analyses.

Summary: The geographical location of West Taihu Lake determines its role as the entrance to the whole Taihu Lake, and the intensive industries around it pose a significant threat to the lake's ecology. In this study, we combined Pb isotope ratio analysis with ecological risk assessment index to quantify the source-oriented ecological risk of heavy metals in the sediments of West Taihu Lake. The results showed that HM pollution in the study area was mainly caused by anthropogenic sources, with moderate ecological risk.

Summary: A sensitive method was developed to monitor natural and synthetic mineralocorticoids in sediment and water from Taihu Lake, revealing the widespread occurrence of these compounds with natural aldosterone being the predominant contaminant. Two new metabolites were discovered, suggesting that spironolactone is more susceptible to degradation in water compared to sediment.

Summary: Identifying phosphorus sources and contributions from terrestrial sources is crucial for managing clean water and eutrophication in lake watersheds. This study investigated the concentrations of different phosphorus fractions in soils and sediments of Taihu Lake, a representative freshwater lake watershed. It also surveyed the phosphorus concentrations in the lake's water. The findings suggest that soil runoff predominantly controls phosphorus occurrence in lake sediments as an exogenous source.

Summary: Research in China's Taihu Lake and surrounding major rivers found varying levels of microplastic pollution, with inflow rivers more affected than outflow rivers. The main components identified were polyvinyl chloride and polyethylene, with differences in average size and distribution observed in different water bodies.

Summary: Global fishery resources are declining, with some fisheries collapsing. Chemical contamination, particularly tris(1,3-dichloro-2-propyl)phosphate (TDCIPP), has been identified as a causal factor for embryonic mortality in crucian carp in Taihu Lake, China. High TDCIPP concentrations were correlated with high mortality rates, posing a threat to fisheries sustainability worldwide.

Summary: This paper provides a detailed investigation of sediment internal P loading in Lake Taihu and its role in algal dominated zones (ADZs) and grass dominated zones (GDZs). The results show that ADZ sediments have higher levels of total P and mobile P fraction compared to GDZ sediments. The study also identifies ADZ as a hotspot for P, with high concentrations of DGT-measured P. Sediment microbial composition is found to be closely related to different P fractions in the sediment. The findings highlight the importance of considering the sediment composition and different management strategies for combating internal P loading in ADZ and GDZ.

Summary: Wuliangsuhai Lake, one of the largest freshwater lakes in China, plays a crucial role in protecting the ecological security of the Yellow River Basin. This study assessed the pollution of heavy metals in the lake and found that the surface sediments are heavily polluted with cadmium and mercury being the main pollutants. Furthermore, the study revealed that the pollution level of sediments decreases with depth.

Summary: Heavy metals are a concern due to their toxicity, persistence, non-degradation, and bioaccumulation. Most countries do not consider the effects of aquatic vegetables when deriving human health ambient water quality criteria. This study added the intake of aquatic vegetables to the derivation of human health AWQC and assessed the health risk for heavy metals in Taihu Lake. The results indicated that the intake of Brasenia schreberi had a significant effect on the human health AWQC for copper.

Summary: Heavy metals in atmospheric dust can pollute soil, water, and sediment, posing a threat to human health. This study focused on the temporal and spatial distribution of heavy metals in atmospheric deposition in western Taihu Lake. Results showed that heavy metal concentrations were higher in winter, lower in summer, and correlated with distance from the city. The health risk assessment values were higher in winter and spring, especially near the city and in suburbs.

Summary: This study investigated cobalt cycling in the eutrophic Meiliang Bay of Lake Taihu, revealing that cobalt in sediments is primarily controlled by manganese redox cycling. Despite minimal changes in dissolved and labile cobalt over one year, cobalt levels in the sediment-overlying water system were strongly regulated by cyanobacterial uptake, suggesting cobalt may be a potential limiting nutrient for cyanobacterial blooms.

Summary: The study found that high biomass of harmful algal blooms (HABs) promotes sulfate reduction into labile sulfur, with iron-reducing bacteria being the dominant species; concentrations of labile iron greatly exceed labile sulfur, indicating microbial iron reduction is the principal pathway. In high algal biomass areas, Fe-P is the primary factor influencing phosphorus migration and transformation.

Summary: The study demonstrates that environmental magnetism combined with machine learning can be effectively used to monitor heavy metal pollution in lake sediments. Analysis of magnetic parameters and heavy metal concentrations in Chaohu Lake sediments revealed ferrimagnetic minerals as the primary magnetic minerals and significant variations in heavy metal concentrations across different seasons, with Cd and Hg posing considerable ecological risks. The utilization of physicochemical indexes and magnetic parameters in predictive models significantly improved accuracy, with SVM showing better performance and potential for efficient long-term monitoring of heavy metal pollution in lake sediments.

Summary: By using a non-parametric risk assessment method and LISA analysis, the combined risks of heavy metals and PAHs pollutants in Taihu Lake sediments were tested. The study showed that the developed method could distinguish pollution hot spots in different regions of Taihu Lake and identified combustion of petroleum fossil fuels as the main source of pollutants.
