Summary: Chemical or biological synthesized iron hydroxides, such as schwertmannite and akaganeite, show high potential for removing chromium ions in polluted wastewater. The adsorption capacity of these materials for Cr(VI) is strong, with maximum adsorption achieved at pH 7.0. Phosphate ions have a greater impact on Cr(VI) adsorption than sulfate and carbonate ions. Moreover, schwertmannite and bioakaganeite exhibit good regeneration ability at temperatures of 288-318 K. Therefore, schwertmannite and bioakaganeite have promising applications in the treatment of acidic/neutral chromate-containing wastewater.

Summary: In this study, a novel nano-scaled schwertmannite (Sch-2.7) was synthesized by adding OH- at a constant pH of 2.7, and it was found to have a high Cr(VI) adsorption capacity. Compared to common schwertmannite (Sch), the addition of appropriate OH- significantly improved the mineral yield, specific surface area, surface group content, and further Cr(VI) adsorption ability of Sch-2.7.

Summary: Good sorption properties and simple synthesis route make schwertmannite an increasingly popular adsorbent. The study compared the properties and sorption performance of adsorbents obtained by Fe3+ hydrolysis and Fe2+ oxidation methods. Results show that both iron-based adsorbents are suitable for removing Cr(VI) ions from aqueous solutions, mainly attributed to ion exchange with SO42- groups.

Summary: The study investigated the adsorption mechanisms of Cr(VI) on schwertmannite surfaces. The experiments revealed that ion exchange reactions with sulfate led to the formation of inner-sphere complexes. XPS and FTIR analysis further confirmed this adsorption mechanism. MCR-ALS analysis showed that the proportion of monodentate and bidentate complexes was influenced by pH fluctuations.

Summary: Schwertmannite as an adsorbent for Cr(VI) removal has been widely studied, but the photoreduction driven dissolution and fate of Cr(VI) loaded on SCH in the presence of dissolved organic matter (DOM) has been limited. This study examined the effect of tartaric acid (TA) on the stability of SCH-Cr(VI) under simulated solar radiation, showing that TA enhanced the release of total Fe while decreasing total Cr. The mechanism proposed involves reduction of Cr(VI) to Cr(III) by Fe(II) generated from Fe(III)-TA(n) via ligand to metal charge transfer.

Summary: This study proposes a method of seed-mediated growth of schwertmannite, which successfully shortens the biomineralization time and enhances the adsorption performance of schwertmannite towards As(V) and Cr(VI). Furthermore, the seed-mediated schwertmannite forms typical needle-like structures during growth, with more loosely arranged whiskers compared to ordinary schwertmannite samples.

Summary: Organo-mineral composites play a vital role in the mobility and bioavailability of toxic metals in natural environments. This study investigates the interactions between citric acid-schwertmannite (CA-Sch) composites and Cr(VI) through macroscopic experiments and spectroscopic analysis. The results enhance our understanding of the behaviors of Cr(VI) on the CA-Sch composite surface and its fate in AMD-contaminated environments.

Summary: This study investigated the competitive sorption of Se(IV) and Se(VI) on different types of schwertmannite at varying initial Se concentrations and mixing ratios. It was found that at lower adsorbate concentrations, an inner-sphere corner-sharing bidentate binuclear complex forms upon exchange with sulphate, while at higher concentrations, both oxyanions become bound to SHM through mainly inner-sphere and partly outer-sphere corner-sharing bidentate binuclear complexes.

Summary: In this study, the Fe(II)-induced transformation of Cr(VI)-substituted schwertmannite was investigated as a function of pH and the degree of Cr(VI) substitution. The results show that higher levels of Cr(VI) substitution inhibit the transformation, partly due to the consumption of Fe(II) by reaction with Cr(VI). This study enriches our understanding of the interactions between hazardous Cr(VI) and schwertmannite in environmental and engineered systems.

Summary: A novel collaborative strategy using nano zero valent iron (nZVI) assisted by schwertmannite (Sch) was designed for enhanced removal of Cr(VI). Batch experiments showed that nZVI/Sch-AP had better removal performance for Cr (VI) than nZVI/Sch-CO. The study provides new insights into the elimination of Cr(VI) from wastewater by nZVI/Sch, especially in acid mine drainage.

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.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. 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.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
