Summary: This study investigates the toxicity of plants to heavy elements and the effects of electromagnetic waves on plant growth stages. Results show high levels of Pb and Cd absorption in Capsicum plants, with HI values exceeding thresholds. The study suggests a significant relationship between certain electromagnetic wave spectrums and the absorption of Pb, Cd, Ni, and Zn in contaminated plants.

Summary: The Biliya Ag-Pb-Zn polymetallic deposit in the Great Xing'an Range, Northeast China, is a low-sulfidation epithermal deposit primarily hosted in quartz porphyry, trachyandesite, and rhyolitic tuff. The mineralization processes involve three stages and are related to magmatic fluids mixed with meteoric water. Boiling and sudden changes in temperature, pressure, and fluid composition are important factors in the formation of the deposit.

Summary: The study used multiple modified biochar (BCM) to stabilize metals in contaminated river sediment. Results showed that BCM effectively reduced the extractability and leachability of multiple metals in the sediment, with minor impacts on Pb and Zn. In addition, BCM significantly increased the content of organic matter and available phosphorus in the treated sediment.

Summary: The study highlights the geochemically interlinked fractionation of Zn and Cd isotopes in groundwater from metallic ore mines in South Korea, with results suggesting precipitation of Zn and Cd as sulfide following sulfate reduction. The use of Zn and Cd isotopes effectively differentiated between adsorption and sulfide precipitation in groundwater, while Pb isotopes were useful in investigating Pb contamination sources in water samples.

Summary: In this study, we analyzed the sulfur isotope data, zircon U-Pb isotope data, sulfide Rb-Sr data, and molybdenite Re-Os data of the Meng'entaolegai deposit and its surrounding regions. The results showed that sulfur was mainly derived from a magmatic source, and the deposit formed during two mineralization episodes: an early episode at 230 Ma and a second episode at 147 Ma.

Summary: The study reveals that Baltic Sea sediments record significant loads of Cd, Zn, and Pb, influenced by redox conditions. Concentrations of these metals increased from the early 19th century to the 1970s, then decreased, but are still above pre-industrial levels. Pre-industrial Cd, Zn, and Pb concentrations were higher than those suggested by the Swedish EPA. The reduction in pollution of these metals since the 1980s highlights the importance of environmental governance.

Summary: The compound 3,7,8-Trihydroxy-3-methyl-10-oxo-4,10-dihydro-1H,3H-pyrano [4,3-b]chromene-9-carboxylic acid is a well-characterized fulvic acid that acts as a polyfunctional bidentate ligand in complexes with metal ions. The study of the formation mechanisms and structure of the FA complexes with bivalent metals is a trending topic in modern chemistry, and theoretical DFT investigations are important due to the lack of experimental structural data. Computational analysis reveals the stability of two out of four possible FA tautomers and provides insight into their properties and reactive ability.

Summary: Southern Hunan Province in China is known for its extensive Mesozoic magmatic rocks and polymetallic deposits. This study focuses on the characteristics of mineralization in this area, particularly the relation between proximal skarn-hosted Cu-Mo and distal carbonate-hosted Pb-Zn mineralization. The research utilizes high-resolution in situ LA-MC-ICP-MS sulfur isotopic compositions to analyze different types of sulfide from the Baoshan polymetallic Cu-Mo-Pb-Zn deposit. The results indicate that the mineralization in the Baoshan deposit is influenced by granodiorite porphyry, carbonate strata, and metamorphic or crystalline basement, with different sulfur isotopic compositions.

Summary: The widespread use of heavy metals and antibiotics in livestock farming and their subsequent presence in agricultural soils pose significant problems for human health and the environment. This study investigated the tolerance and co-tolerance of bacterial communities in soils polluted with heavy metals and antibiotics. The findings suggest that bacterial communities in polluted soils exhibit increased tolerance and co-tolerance to both heavy metals and antibiotics, which has important implications for understanding the transmission of antibiotic resistance genes to human pathogens.

Summary: Acquiring long-term time series of climate, hydrology, and hydrochemical data is crucial for understanding the complex interactions in the Critical Zone. Despite the importance of humid tropical regions in terms of population density and land use, few Critical Zone Observatories are located in these areas. Data shared by M-TROPICS in Cameroon have contributed to understanding water partitioning, chemical weathering, and erosion processes in tropical ecosystems. The fluctuating solute concentrations at the Nyong River tributary outlet highlight the need for longer time-series and ongoing support for CZOs in the humid tropics.

Summary: Mapping soil properties is becoming more challenging due to human modifications of the landscape. The traditional practice of applying tank silt to agricultural fields in South India is beneficial for soil fertility, but the extent of this practice needs further investigation. The study demonstrates the potential of using Sentinel-2 images to accurately map tank silt application and evaluate soil color changes related to this practice.

Summary: Organic matter management is crucial for sustaining soil ecosystem services, but its holistic consideration in terms of local resources, agro-environmental effects, and farmers' needs is often overlooked. Organic inputs like compost and biochar offer a sustainable solution to the challenges of intensified agriculture, especially in tropical regions. This study assesses the potential of agricultural residues as resources for farmer communities in southwestern India to reduce their dependence on external inputs and maintain ecosystem services.

Summary: Climate change, variability, and land use change are the main drivers of river discharge variability. The decrease in rainfall is synchronous with the decrease in discharges in large basins, while it is concomitant with an increase in a small basin. Land use change has an impact on extreme discharges, with increases in impervious areas and reductions in forest cover leading to changes in discharge patterns. Precipitation in the dry season affects the flows in the following rainy seasons. The impact of precipitation on discharge varies in different seasons and time periods.

Summary: Due to climate and environmental changes, sub-Saharan Africa has been experiencing drought and flood events, impacting the economy of the region. This study specifically focuses on the So'o River Basin in Cameroon and analyzes the current and future flows using hydrometeorological time series and simulation models. The results suggest a decrease in river discharge due to a decrease in precipitation for the current period and a possible decrease in future periods, except under certain scenarios where a slight increase is projected.
