Summary: This study focuses on the geochemical conditions of suspended sediments in the Laguna estuarine system in southern Brazil, particularly around the main South American coal plant, in order to inform future environmental recovery projects and policy-making. Nanoparticles react with constituents of nature and undergo active alterations, with contamination from engineering activities and wastewater being identifiable sources, but issues arise when these contaminants interact with other pollution sources. By examining concentrations of toxic element contaminants and occurrences of nanoparticles, the study provides new insights into pollutant interactions and the potential impacts on estuarine systems in Brazil.

Summary: This study proposes an improved interpolation-based RDPCA method, which takes the PWV derived from ERA5 as an additional aid, to interpolate missing data in precipitable water vapor derived from global navigation satellite systems. The performance of the IRDPCA is compared with RDPCA and DINEOF using simulation experiments, and the results demonstrate the superior performance of the IRDPCA in both the heterogeneous and homogeneous cases. Furthermore, these methods are also applied to the interpolation of the real GNSS-PWV, and the interpolated GNSS-PWV using the IRDPCA is not impacted by the systematic discrepancies in the ERA-PWV and agrees well with the original data.

Summary: Estimating the grade of ore is crucial for evaluating its value and determining the development of mineral resources. To enhance the accuracy of the inverse distance weighting (IDW) method and mitigate its smoothing effect, the weight calculation method was improved by incorporating the length of ore samples. This led to the development of a new IDW method called IDW integrated with sample length weighting (IDWW). The IDWW method was verified through the estimation of Li, Al, and Fe grades in porcelain clay ore, and its deviation analysis demonstrated its accuracy and stability compared to the IDW method. The experimental scheme considered various factors affecting grade estimation, and the IDWW method effectively reduced smoothing and improved sample utilization efficiency. Grade estimation deviations were influenced by the number of samples and the shape of the grade distribution. The IDWW method offers theoretical advantages and addresses the adverse effects of uneven sample lengths. Rating: 9 out of 10.

Summary: This paper investigates heavy metal pollution in agricultural fields near the largest landfill in Senegal by comparing total concentrations and speciation of heavy metals. The majority of heavy metals are bound to the residual fraction, making them less likely to be released into the environment. The metal pollution is more severe in certain sampling sites, and the exchangeable fraction in the soil suggests that some elements may be easily released. Some vegetables analyzed had high concentrations of certain heavy metals, but consuming them does not pose significant health risks except for cassava and cassava leaves.

Summary: This study evaluates the sources and controlling factors of groundwater contaminants in an agroeconomic region of the Lower Ganga Basin. The findings indicate that the dissolution of fluoride-bearing minerals and semi-arid climate regulate fluoride concentrations in groundwater, while the extensive use of inorganic nitrogenous fertilizers and livestock manure contribute to elevated nitrate levels. The health risk analysis reveals that fluoride exposure is more prevalent in residents of all age groups compared to nitrate, and both contaminants pose higher non-carcinogenic health risks to infants and children.

Summary: The presence and geochemical composition of olivine on Mars are important for studying the planet. Raman spectrometers, used in Mars 2020 and future missions, provide new possibilities to determine the Mg/Fe ratios in olivine-bearing rocks. Olivine's presence indicates past volcanic activity on Mars, and its forsterite/fayalite ratio can reveal information about the origin and evolution of the parent magma. This study proposes a new calibration model using Raman spectroscopy, greatly improving the accuracy and uncertainty associated with the forsterite/fayalite ratios compared to previous literature.

Summary: This study reports the synthesis of magnetic graphene oxide (GO Fe3O4) with different amounts of iron nanoparticles for the adsorption of furosemide (FUR). The optimal adsorbent was found to be GO Fe3O4 1:1, with a removal percentage and adsorption capacity of 96.15% and 96.91 mg g-1, respectively, at pH 3.0 and 293.15 K. The process was influenced by initial concentration, adsorbent dosage, and pH, while the ionic strength had minimal effect on the performance of GO Fe3O4 1:1. Sips and PSO models were the best fit for the experimental data, indicating a heterogeneous surface. GO Fe3O4 1:1 exhibited high removal percentage even after several cycles of adsorption/desorption.

Summary: This study investigated the recovery of Gd3+ from real leachate of phosphogypsum using natural bentonite clay. The adsorption study revealed that the clay has typical bentonite characteristics and can effectively adsorb Gd3+. The kinetics and thermodynamics of the adsorption process were analyzed, and it was found that the Langmuir model and Avrami fractional order model were suitable for describing the adsorption isotherms and kinetic data, respectively. The study also showed that citric acid was an efficient desorbing agent for Gd3+ from the bentonite, and the clay could selectively recover Gd3+ from the real leachate of phosphogypsum.

Summary: This study investigated the adsorption and recovery of cerium (Ce(III)), a rare earth element, from an aqueous solution using a sustainable hydrochar made from wood waste. The hydrochar contained various surface functional groups, which significantly influenced its adsorption capacity. The pH of the solution strongly affected the Ce(III) removal, with the highest removal efficiency achieved at pH 6.0. The hydrochar exhibited high efficiency in Ce(III) adsorption, with a maximum adsorption capacity of 327.9 mg g(-1) at 298 K. The adsorption kinetics followed the general order model, while the equilibrium process fit the Liu isotherm model. The Ce(III) adsorption mechanism on the hydrochar involved electrostatic interactions and chelation between surface functional groups and Ce(III). The hydrochar also demonstrated excellent regeneration capacity using sulfuric acid as an eluent. This research presents a sustainable approach for developing an efficient adsorbent for Ce(III) removal with excellent physicochemical properties.
