Dark formation of hydroxyl radicals (•OH) from soil/sediment oxygenation has been increasingly reported, and solid Fe(II) is considered as the main electron donor for O2 activation. However, role organic matter (SOM) in •OH production not clear, although it represents an important pool subsurface. In this study, reduced humic acid (HAred) was investigated at pH 7.0. linearly correlated with electrons released HAred suspension. Solid transferred rapidly to via surface-reduced moieties (hydroquinone groups), which fueled by slow transfer inside HA. Cycling dissolved HA between oxidized states could mediate enhancement. Modeling results predicted that SOM played or even dominant soils sediments possessing high molar ratios SOC/Fe(II) (e.g., >39). The significant contribution further validated modeling 88 soils/sediments literature. Therefore, should be carefully comprehensively understand SOM-rich subsurface environments.

Iron (hydr)oxides as a kind of natural mineral actively participate in the transformation organic pollutants, but there is large knowledge gap their impacts on photochemical processes microplastics (MPs). This study first to examine degradation two ordinary plastic materials, polyethylene (PE) and polypropylene (PP), mediated by iron (goethite hematite) under simulated solar light irradiation. Both significantly promoted MPs (particularly PP) with greater effect goethite than hematite, related hydroxyl radical (•OH) produced (hydr)oxides. Under irradiation, surface Fe(II) phase catalyzed production H2O2 release Fe2+, leading subsequent light-driven Fenton reaction which amount •OH. As were modified NaF at various concentrations, activity well Fe2+ greatly reduced, thus •OH formation MP depressed remarkably. It worth noting that groups (especially ≡FeOH) affected kinetics regulating Fe species. These findings unveil distinct intrinsic mechanisms influencing photodegradation MPs.
