Summary: The influence of domestic wastewater on the stability and fractionation of trace metals in sediment was investigated through leaching experiments. The results showed that domestic wastewater had no negative impact on the stability of trace metals, and the presence of phosphate was the main factor determining this phenomenon.

Summary: Heavy metals have negative effects on human health and biogeochemical cycles in freshwater habitats. Lake Nasser, the main freshwater source in Egypt, is often polluted by human activities upstream in the River Nile basin. The study concludes that the water of Lake Nasser is safe for human consumption, agricultural use, and public sanitation.

Summary: Limited knowledge of the combined effects of water and sediment properties and metal ionic characteristics on the solid-liquid partitioning of heavy metals constrains the effective management of urban waterways. The study revealed that high salinity can increase the solubility of weakly-bound metals, while dissolved organic matter does not favor metal solubility.

Summary: It is essential to assess the contamination of heavy metal (HM) in lakes in dissolved matter, suspended particular matter (SPM), and sediments. This study evaluated the risks of HMs in Caohai, China, in water, SPM, and sediment, and analyzed the changes in sediment HM contamination with historical data. The transport of HM was mainly influenced by SPM load, and the concentrations of Zn, Pb, and Cd in SPM and sediment were significantly higher than the upper continental crust (UCC) values. SPM and sediments were polluted and had high toxicity risks, originating from industrial and agricultural sources. The concentrations of Zn, Pb, and Cd in Caohai sediments showed an increase compared to previous years. This research provides valuable reference data for the remediation of polluted karst lakes.

Summary: Metal bioavailability, especially in the context of biochar amendment, influences its behavior in the soil-plant system. This study compared two methods for analyzing cadmium (Cd) bioavailability in Chinese soils, finding that biochar reduced bioavailable Cd levels in soil and decreased Cd accumulation in lettuce roots and leaves. Soil pore-water Cd was identified as the best predictor for Cd accumulation in lettuce, with transfer factor values indicating lower Cd movement from roots to leaves. Soil properties and pore-water Cd together were found to contribute significantly to root enzyme activities.

Summary: The study investigated the occurrence, ecological risk, and sources of heavy metals in the Liaohe River Protected Area from the Bohai Sea watershed. Results showed water, sediment, and soil in the area were contaminated with heavy metals, with Cd, Pb, As, Cr, and Zn being the most prominent pollutants. Sites L25 and L12 were classified as moderately polluted based on the potential ecological risk index values for sediment and soil, respectively.

Summary: This study evaluated the heavy metal pollution in Beys,ehir Lake, the largest freshwater lake in Turkey. The concentrations of heavy metals in lake water and sediment samples were determined, and various index methods were applied. The results showed that the heavy metal concentrations in lake waters were below the limit values and suitable for drinking water. The risk of heavy metal contamination in lake sediments was also low.

Summary: The study reveals that the mineralogical composition of sediments plays a crucial role in the adsorption and desorption of heavy metals. Particulate organic matter is the most influential nutrient in heavy metals adsorption in riverine environments, while particulate phosphorus is more significant in estuarine conditions. Dissolved nutrients do not have a significant positive effect on the release of heavy metals in riverine areas, but dissolved phosphorus increases the transfer of specific metals from sediments to overlying water in estuarine conditions.

Summary: Groundwater with low levels of arsenic in deep aquifers has been overexploited, leading to the compaction of clayey aquitards and the release of arsenic through processes such as reductive dissolution of iron oxides and desorption from Fe (hydr)oxides. The dominant release mechanism of arsenic during clayey aquitards compaction shifts from reductive dissolution to desorption as pressure increases, with eventual weak release from clay or carbonate minerals. Our estimate suggests that arsenic concentration released from aquitard compaction into groundwater ranges from 9.33 to 118.09 μg/L in the Jianghan Plain.

Summary: This study investigated the heavy metal pollution in water and sediment during different seasons and identified the factors causing this pollution. It was found that both natural sources such as soil erosion and anthropogenic sources like runoff from urban and agricultural areas contribute to metal concentrations. The depth of water and soil transport also play a role in metal accumulation.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
