Summary: China possesses abundant lead-zinc mineral resources, but mining activities often result in severe heavy metal contamination. This study comprehensively evaluated the contamination levels of eight heavy metals in mine tailings, soil, and groundwater from 27 contaminated sites in China. The levels of contamination were assessed using various indices, and the results showed high concentrations of Zn, Pb, and Cd, posing significant environmental risks. The study also highlighted the correlation between heavy metal content in soil, groundwater, and mine tailings, identifying them as the primary pollution sources and transport pathways. The findings provide valuable insights for assessing the pollution levels in lead-zinc mining regions and guiding the remediation activities for abandoned mining and tailings in China.

Summary: This study provided an integrated assessment of potentially harmful elements (PHE) in the soil-plant-tailing system after the Fundao Dam disaster in Brazil. The deposition of iron waste (DIW) caused contamination of Fe and Mn, but not other harmful elements. The covering of DIW with control soil resulted in undesirable enrichment of Pb in floodplain soils. Overall, the iron waste does not pose a long-term threat to PHE contamination in soils between Fundao and Risoleta Neves Hydroelectric Dam.

Summary: MiSeq high-throughput sequencing methods were used to study the bacterial diversity and community structure composition in Pb-Zn tailing soils in the Qinling Mountains. The results showed that the soils of the two tailings were polluted by heavy metals to different degrees, and that soil chemical properties and heavy metal concentrations affected bacterial community structure jointly. pH, soil organic matter, total nitrogen, and heavy metals Cd, Zn, and Pb were identified as the main influencing factors on the soil bacterial community structure of the tailings.

Summary: Elevated soil lead concentrations in East Chicago were widespread and above regulatory limits, with levels increasing in neighborhoods with lower median household income. The soil lead was primarily adsorbed to iron and manganese oxides or humic acids, regardless of contamination levels. The lack of detectable crystalline insoluble forms of lead suggests that potential sources such as paint, ore, and slag are repartitioned into more bioavailable forms in the soil. These findings have implications for remediation efforts and human health due to significantly elevated blood lead levels in the community.

Summary: Extracellular polymeric substances (EPS) are highly hydrated matrices produced by bacteria, containing various polymers such as polysaccharides, proteins, lipids, and DNA. EPS contributes to physical stability and nutrition acquisition for bacteria. Specific glycosyltransferases, polymerase, and transporter proteins encoded by operons regulate the biosynthesis of different EPS in bacteria. EPS can interact with environmental pollutants through functional groups, such as carbonyl, hydroxyl, phosphoryl, and amide, and bind pollutants through hydrophobic interactions and coordinate bonds. EPS can enhance the degradation of organic compounds and bind heavy metals via complexation, surface adsorption, precipitation, and ion exchange mechanisms. The biodegradability and nontoxicity of EPS make it a promising biopolymer for environmental pollutant decontamination.

Summary: The characteristics and resistant mechanisms of macro-fungus endophytic bacteria to cadmium were explored in this study. It was found that under cadmium stress, the morphology of the bacteria changed to reduce the threat of cadmium. Functional groups like -OH, -COOH, and -NH2 were found to play a role in the cadmium adsorption process. Additionally, the adsorption of cadmium in the sterilized strains was higher compared to the living ones.

Summary: This study integrates various models to analyze the historical and future evolution, spatial-temporal collaborative relation, and input-output efficiency of water ecological carrying capacity (WECC) in the Beijing-Tianjin-Hebei (BTH) and Yangtze River Economic Zone (YREZ). The results show that WECC level is generally increasing in both regions, with different preferences for monitoring water resources and socio-economic subsystems. The combination prediction model has lower error and the binary matching degrees are above medium state. The findings suggest the need for improving regional WECC and rational planning of water resources.

Summary: The development of the Ranque-Hilsch vortex tube has been stagnant since the 1950s, and its performance has remained constant for 70 years. The lack of a mature design method and unclear flow structure and energy separation mechanism have limited its widespread industrial adoption. This study investigates the relationship between cooling performance and the area ratio of a vortex tube and suggests that the inlet mass flowrate per unit area can be a geometric performance benchmark.

Summary: This paper studies the stability of shield tunnel excavation surface and its influencing factors through field investigations and tests, and deduces equations for solving the limit support pressure and safety factor of the excavation surface. The single reduction method and the double reduction method are used to solve the safety factor under basic working conditions, and a numerical simulation method is clarified. Based on FLAC3D software, the stability of the excavation face is evaluated using the ultimate support pressure and safety factor, and the response of factors such as internal friction angle, cohesion, and hole diameter are analyzed. The internal friction angle has the greatest impact on the stability of the excavation surface.

Summary: Ti particles addition in Mg AZ31/Al 6082 composite sheets prepared by hot rolling was investigated in this study to understand the influence on mechanical behavior and microstructure. The results revealed that Ti particles were uniformly distributed at the interface, leading to a reduction in Mg-Al intermetallic compounds during annealing treatment. After annealing, the Mg/Al-Ti sheet exhibited improved tensile strength and elongation compared to the Mg/Al sheet. Ti particles addition had minimal effect on the grain size, texture type, and tensile fracture morphology of the Mg and Al layers in the composite sheets. This study provides a new perspective on understanding Mg/Al composites through the addition of metal particles.

Summary: A new type of pneumatic flexible arm is developed to address the weak driving ability and low torsional stiffness issues. The arm utilizes three fan-shaped driving cavities and a convex-concave nested constraint ring structure. Static experiments were conducted to verify the theoretical model, which showed consistent results. By adjusting the pressure of the driving cavities, the flexible arm can bend in any direction within a 0°-360° range and at any angle within a 0°-98° range. It overcomes the limitations of weak driving ability and anti-torsion ability, providing flexibility for various applications in service, medical treatment, and rescue fields.

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.

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.
