We investigated how the basalt weatheringstate influences mineral-associated organic matter (MAOM) in a 6 monthmicrocosm incubation of a slightly acidic Cambisol. Fresh basalt (olivine-rich)and naturally weathered basalt (olivine-depleted and phyllosilicate-enriched)were applied, and 13C-labeled straw was used to trace theincorporation of plant-derived C into MAOM. Fresh basalt caused morenative MAOM-C loss (∼13%) by 0.86 ± 0.29 mg of C (g ofsoil)−1, likely driven by pH, whereas weatheredbasalt caused minimal pH change and marginal native MAOM-C loss (∼0%)compared to the control. In 13C-labeled straw-amended soils,weathered basalt, characterized by a larger specific surface areaand limited pH alteration, increased straw-derived new MAOM-C formationby 20% and 8.5% compared to fresh basalt and the control, respectively.These microcosm incubation results suggest that basalt weatheringwithin 6 months of application may strongly modulate native MAOM-Closs and new MAOM-C formation. Our findings indicate that ERW caninfluence soil MAOM-C beyond IC sequestration, which implies the needto include MAOM-C responses in ERW carbon accounting to improve itsclimate mitigation potential assessments.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"13 8","pages":"1108–1113"},"PeriodicalIF":7.3,"publicationDate":"2026-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148709709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While no plastic particles(> 2 mm) were detected in surface sediments, all examined Diopatra tubes (n = 48) contained plastics,averaging 4.73 plastic particles per tube. Both Diopatra abundance and tube-entrapped plastics increased with distance fromthe shoreline, suggesting hydrodynamic mediation of habitat suitabilityand plastic retention. FTIR spectroscopy revealed that fibers dominatedthe incorporated plastics, primarily derived from Abandoned, Lost,or otherwise Discarded Fishing Gear (ALDFG). Notably, per-tube plasticloads substantially exceeded ingestion-based accumulation levels reportedfor other benthic invertebrates, underscoring bioconstruction as adistinct and more efficient retention mechanism.

Overlooked as a common nuisancein groundwater systems, natural iron has the potential to be usedas an autochthonous catalyst in the abatement of organic contaminantsvia Fenton oxidation, a well-known AOP. However, its usefulness ishindered by the circumneutral pH of groundwater, which leads to itsprecipitation upon reacting once with ROS-generating oxidants suchas hydrogen peroxide. As a solution to this issue, we developed anovel electrochemical flow-through system which enhances oxidationof organic pollutants via anodic redissolution of Fe3+ andcathodic regeneration of Fe2+. The electrochemically enhancedFenton system displays excellent capacity for treating high concentrationsof various pollutants in a single pass, using high, but environmentallyrelevant, levels of ferrous iron as the sole source of catalyst. Moreover,the modular, decentralized cell design and use of cheap graphite feltelectrodes enables practical and energy efficient degradation of contaminants,well-suited for point-of-use applications.
