Summary: Through investigating the variations of arsenic (As) in mine wastewater, it was found that under flooded condition, As(III) can be immobilized while As(V) can be activated in paddy soil, which influences the mobility of As. During drainage, available As is mainly immobilized by Fe oxyhydroxides and humic substances, and adsorbed As(III) is oxidized. These results provide an estimation pathway for the impacts of key biogeochemical cycles on exogenous As species under a redox-alternating condition.

Summary: This study investigates the electron transfer between electron shuttling compound cysteine (Cys) and hematite, as well as the relocations of surface-bound arsenic (As). The results show that the electron transfer generates Fe(II) and leads to reductive dissolution, with more Fe(II) generated on {001} facets of exposed hematite nanoplates (HNPs). Reductive dissolution of hematite significantly enhances the relocation of As(V) on hematite, but the rapid release of As(III) can be halted by the addition of Cys, leading to unchanged immobilization of As(III) throughout the course of reductive dissolution.

Summary: In this study, a direct growth of amorphous metal oxyhydroxide (AMO) attached on CeO2 as an advanced oxygen evolution reaction (OER) catalyst was successfully demonstrated through a galvanic replacement mechanism. The CeO2 substrate provides a high specific surface area and high conductivity for the formation of AMO, ensuring promoted electron transfer for the catalytic reaction. The AMO on the CeO2 surface exposes abundant active sites for the OER, leading to excellent OER performance of the prepared AMO@CeO2 supported on nickel foam.

Summary: The rhizosphere is a highly biogeochemically active site that influences soil formation processes such as mineral weathering. Contrasting biogeochemical environments were found between the rhizosphere and bulk soils in Technosols, with the former having lower pH values, higher dissolved organic carbon concentrations, and increased enzymatic activity. The transformation of primary minerals in the rhizosphere, triggered by higher biological activity, led to the release of key nutrients into the soil solution and the formation of amorphous Si phases.

Summary: Galician Rias are highly productive ecosystems with salt marshes and sediments that promote pyrite synthesis and accumulation. This study examines the morphological variability and concentration of pyrites in the Ria de Ortigueira, finding that framboidal pyrites dominate in marsh soils and sediments in the inner and middle sections, while isolated crystals dominate in the outer section. Lower marsh soils show the highest pyrite synthesis, but lower amounts of framboidal pyrites compared to the inner and middle sections. Pyrite crystals in the sediments indicate degradation and derive from marsh collapse.

Summary: This study analyzes the impact of COVID-19 lockdown on the spatiotemporal variability of ozone (O3), sulfur dioxide (SO2), and nitrogen dioxide (NO2) concentrations in different provinces of continental Ecuador using satellite information. The results show a significant decrease in NO2 concentrations during the lockdown period in all study areas, while NO2 concentrations increased by over 20% in the period after lockdown. SO2 concentrations showed irregular variations during lockdown, but increases were observed in certain provinces due to volcanic activity. Conversely, O3 concentrations increased in the study areas, possibly due to decreased levels of NOx.
