Summary: Anthropogenic activities release heavy metals into the atmosphere, and Pb and Zn isotopes can be used to determine their sources. The study found that the Pb in sediment cores from a lake in South China is mainly from trans-boundary transportation, with 72.3% coming from previously industrialized countries, indicating a significant legacy of heavy metals in China since 1900. Additionally, Chinese gasoline still contributes to heavy metal pollution, and China's mining and smelting activities have steadily increased their contribution to Pb since 1980.

Summary: In this study, a combination of electrokinetic and chemical immobilization was used to remediate Cd and Pb polluted river sediments. The immobilization ratios for Cd and Pb were achieved by adjusting the concentrations of the immobilization reagents and the applied voltage. The enhancement effect of the electric field is mainly due to the increased contact between the immobilization reagents and the heavy metals.

Summary: This study investigated the long-term effects of sediment improvement and submerged plant restoration on the ecosystem of a sub-tropical shallow urban lake in Hangzhou West Lake, China. The results showed that the restoration project decreased sediment phosphorus and organic matter, increased submerged plant biomass and sediment microbial diversity, and improved the benthic macroinvertebrate communities. These findings have significant implications for the ecological management of shallow lakes.

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: Intensive anthropogenic activities, specifically, industrial and agricultural production, have led to the accumulation of heavy metals in lake sediment, posing threats to aquatic ecosystems and human health. Evaluating the potential ecological risk of heavy metals in lake sediment is crucial for effective lake management. However, large-scale risk evaluations of heavy metal pollution in lake sediment are lacking in densely populated countries like China. This study compiled data from 190 lakes across five geographic zones in China and evaluated the ecological risk and sources of heavy metals in lake sediment, providing valuable insights for policy formulation and lake restoration.

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 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: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
