Summary: In this study, natural diatomite and Mn-modified diatomite were found to be effective for the adsorption of Basic Blue 41 from aqueous solution at different temperatures. The Freundlich isotherm model showed better performance, with higher isotherm constants indicating favorable removal at higher temperatures. Economic analysis suggested that diatomite could be a cost-effective alternative to more expensive adsorbents for dye removal.

Summary: Fluorine is a common element that is found in various forms and concentrations in the Earth's crust, air, food, and natural waters. Its effects on human health depend on the absorbed concentration, with low levels being beneficial and high levels being toxic. Adsorption using modified zeolites has been proven to be an efficient and cost-effective method for removing fluoride from water. The study investigated the adsorption process and determined influential parameters such as particle size, stirring rate, pH, initial concentration, contact time, and temperature. The findings showed that modified zeolite had a 94% removal efficiency at specific conditions.

Summary: This study compares the adsorption ability of clays and dead microorganisms against special toxic gases. Experimental investigations were conducted on kaolinite, metakaolinite, radiolarite, and diatomite for their adsorption kinetics to ammonia, ethylene, and carbon dioxide. Various analyses were performed for mineralogical and structural characterization of the materials. The results show that diatomite has the highest uptake efficiency among all materials, while metakaolinite has a lower response due to phase transformation. The adsorption behaviors are clarified with Langmuir isotherms, providing insights for using microorganisms as natural adsorbent materials in toxic gas environments.

Summary: Slow-release materials are used to control the slow-release of drugs. Polymer slow-release materials have been extensively studied but have poor stability and difficulty in controlling the release effect. Diatomite, a lightweight and stable mineral, was used to prepare a series of diatomite-based porous slow-release materials to explore their adsorption-release performance. These materials displayed excellent porous structure and adsorption-release properties. The adsorption process of phoxim onto the slow-release materials followed the Freundlich model, with a maximum adsorption capacity of 217.86 mg g-1 at 25°C. Moreover, the release effect of phoxim from the materials was significant under acid or high temperature conditions, with release amounts of 60.04% and 80.2%, respectively. The slow-release time was up to 25 days, which effectively reduced the residue of phoxim. The release process was controlled by the Fick diffusion mechanism according to the fitting results of the Ritger-Peppas model.

Summary: In this study, a one-step hydrothermal method was used to synthesize two-dimensional layered Laponite nanosheets on the three-dimensional biological template diatomite. The adsorption performance of the synthesized Laponite@diatomite nano-adsorbent for cationic dye removal was investigated. The results showed that La@D-0.1 had the highest adsorption efficiency and exhibited excellent adsorption capability for methylene blue solution. This work provides a novel idea for the synthesis of an economical and ideal nano-adsorbent for cationic dyes and its potential application in wastewater purification.

Summary: This study quantifies the contributions of adsorption, bioreduction, and desorption in EPS-mediated U(VI) immobilization. Experimental results show that U(VI) immobilization is faster when exposed to H-2 compared to O-2. The kinetic model reveals that adsorption is dominant in the first minute, bioreduction is dominant from the second minute to the 50th minute, and after 50 minutes, bioreduction is balanced by desorption. This study also provides the first set of equilibrium data for U(VI) adsorption by EPS alone and shows that U(VI) adsorption onto EPS is endothermic, spontaneous, and favorable at higher temperatures.

Summary: In this study, natural Tunisian diatomite powder (ND) and diatomite modified by activated carbon and beads (DAA) were used to eliminate Methylene blue (MB) and Congo red (CR) dyes. The effects of different parameters such as pH, temperature, and initial concentration on the adsorption process were examined. Results showed that ND removed 73.15% (19.95 mg/g) of MB and 72.63% (44.93 mg/g) of CR. However, the percentage increased to 96.72% (30.02 mg/g) for MB and 97.21% (85.32 mg/g) for CR after combination with alginate and activated carbon. The adsorption kinetics followed the pseudo-second-order model, and the Freundlich isotherm described the adsorption of dyes. Thus, this study confirms the important role of the DAA composite in removing both cationic and anionic dyes.

Summary: A new catalyst based on biosilica doped with palladium(II) chloride nanoparticles was prepared and tested for efficient degradation of methyl orange in water solution under UV light excitation. The photocatalyst exhibited excellent photodegradation activity toward MO degradation under UV light irradiation, showing rapid photocatalytic degradation within one minute with an efficiency reaching over 98% after 75 min. The proposed mechanism of photodegradation involves the generation of strongly oxidizing species such as HO· and O2·- radicals from diatom biosilica under the influence of UV light excitation.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
