Summary: This study investigated the combined impacts of algae bloom and its induced variations in heavy metals on microbial community in sediment from a eutrophic lake. The results showed that algae bloom increased the quantity of water soluble organic matter and redistributed the spatial patterns of heavy metals in sediment. The bloom also decreased the richness and diversity of sediment bacterial community, with the combined impacts of algae-induced changes explaining 66.56% of the variations in bacterial community structure.

Summary: This study investigated the water quality and risk assessment of the surrounding rivers in the Chaohu Lake Basin in China. The results showed that the mining industry was the main source of river pollution in the area. High concentrations of most elements were found in rivers located in the northwestern part of the basin. The study also revealed that the river samples required treatment before irrigation, but most of them had excellent water quality for drinking. The ecological risk assessment indicated low risks, while the health risk evaluation suggested higher carcinogenic risks associated with certain elements.

Summary: This study uses a 3-D hydrodynamic-ecological model to assess the impacts of water transfer on flow and water quality in Lake Chaohu. Results show that clean water transfer can increase flow rate and decrease nutrient concentrations near the transfer inlets. The best improvement in flow rate and water quality is achieved through clean water transfer via the eastern route. Winter water transfer is more effective for improving total nitrogen and total phosphorus, while summer transfer is better for ammonia nitrogen. Decreasing wind speed is essential for mitigating nutrient accumulation in the heavily polluted bay of the western lake.

Summary: This study assessed the water quality in the rivers of Lake Chaohu Basin, finding a moderate overall water quality state with significant seasonal variations. Three distinct groups were identified based on 15 environmental parameters. The minimum water quality index (WQI(min)), consisting of 5 crucial parameters, showed no significant difference from the WQI based on all parameters and has the potential for universal application in river water quality assessment in different basins.

Summary: This study conducted an ecological and human health risk assessment of metals and heavy metals in Qinghai Lake, the largest inland saltwater lake in China. The concentration, distribution, and source of these metals were investigated. It was found that the metals in the sediments of Qinghai Lake mainly came from five rivers entering the lake, with copper and zinc showing the highest enrichment capacity. The results of the risk assessment indicated low ecological risks and no threat to human health from the heavy metals in the lake's sediments.

Summary: The separation of copper and arsenic has always been a major issue in the copper slag flotation process, with the presence of arsenic-copper alloys increasing the difficulty of separation, requiring finer grinding. Arsenic is oxidized into arsenate compounds during the process, while the transformation of copper and arsenic speciation affects the selectivity of separation. The study also highlights the risks of heavy metals in FSF slag and its flotation concentrate, emphasizing the need for cautious handling and utilization.

Summary: Gallium (Ga) and germanium (Ge) are strategically critical rare elements (CREs) with increasing demand for emerging energy-efficient technologies and high-tech applications. Understanding the redistribution behavior of Ga and Ge during combustion in coal is essential for the development of CREs enrichment and extraction technologies. Adding Si, Al, Na, and K-based compounds can enhance the redistribution of Ga and Ge to ash phases during high-temperature combustion, which shows potential for efficient capture of these CREs in future applications.

Summary: This study examined the sources and temporal variation of polybrominated diphenyl ethers (PBDEs) in Chaohu Lake in eastern China. The results showed that PentaBDE and OctaBDE commercial mixtures were widely used around the lake, with municipal sewage effluent being a major source of PBDEs in the surface sediment. The concentrations of BDE-47 and BDE-99 in this study were in the middle range of global data, but BDE-183 concentrations were relatively high. Overall, this study contributes to a better understanding of the sources and environmental fate of PBDEs in the studied lake.

Summary: This study investigates the feasibility of immobilizing hexavalent chromium (Cr(VI)) in the soil-plant environment using calcium silicate hydrate (C-S-H) synthesized from coal gangue. The results show that C-S-H amendment increases soil pH and organic matter (OM), facilitating the immobilization of Cr(VI). The results suggest that C-S-H is a practical and environmentally friendly amendment for in-situ immobilization of Cr(VI) contaminated soil, promoting plant growth and reducing the toxic effects of Cr(VI).

Summary: The increasing consumption of coal has led to a significant accumulation of coal gangue. Reusing and recycling coal gangue is crucial for sustainable development. A ceramsite adsorbent made from coal gangue, coal fly ash, and copper slag was prepared for efficient copper ions adsorption. The optimal mixture of coal gangue, coal fly ash, and copper slag had a weight ratio of 3:4:1. The ceramsite had crystalline phases of quartz, mullite, and anorthite, with micropores connecting the interior and surface. It displayed a maximum copper ions adsorption capacity of 20.6 mg/g at 303 K, with a pH of 5 and a time of 1440 min. The adsorption kinetics followed the pseudo-second-order model, and the adsorption isotherm fit the Freundlich model. The mechanisms of copper ions adsorption were attributed to precipitation of Cu(OH)(2) on the alkaline surface of the ceramsite and complexation reactions with O-containing groups from the ceramsite.

Summary: Understanding the behavior of heavy metals in mining areas is crucial for controlling mining pollution. This study examined the concentrations and migration patterns of As and other heavy metals in gold mining wastes and surrounding soils. The results revealed high concentrations of As, indicating severe pollution in the soil. Furthermore, the weathering oxidation products from the mining wastes were found in the soils, indicating the migration of mineral particles and heavy metal accumulation. The risk assessment showed low risk from As, but its environmental impact cannot be ignored due to its high mobility.
