Mineral-mediated stability of organic carbon in soil and relevant interaction mechanisms

Eco-Environment & Health, Journal Year: 2024, Volume and Issue: 3(1), P. 59 - 76

Published: Jan. 3, 2024

Soil, the largest terrestrial carbon reservoir, is central to climate change and relevant feedback environmental health. Minerals are essential components that contribute over 60% of soil storage. However, how interactions between minerals organic shape transformation stability remains poorly understood. Herein, we critically review primary mechanisms, including sorption, redox reaction, co-precipitation, dissolution, polymerization, catalytic reaction. These interactions, highly complex with combination multiple processes, greatly affect through following processes: (1) formation or deconstruction mineral-organic association; (2) oxidative minerals; (3) polymerization (4) varying association according mineral transformation. Several pieces evidence related turnover during interaction in real eco-environment then demonstrated. We also highlight current research gaps outline priorities, which may map future directions for a deeper mechanisms-based understanding storage capacity considering its minerals.

Water Vapor Condensation on Iron Minerals Spontaneously Produces Hydroxyl Radical

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(23), P. 8610 - 8616

The hydroxyl radical (•OH) is a potent oxidant and key reactive species in mediating element cycles pollutant dynamics the natural environment. source of •OH historically linked to photochemical processes (e.g., photoactivation organic matter or iron minerals) redox chemical reaction microbe-excreted reduced iron/natural matter/sulfide-released electrons with O2 soils sediments). This study revealed ubiquitous production via water vapor condensation on mineral surfaces. Distinct productions (15–478 nM condensation) were observed all investigated minerals abundant occurrence (i.e., goethite, hematite, magnetite). spontaneous triggered by contact electrification Fenton-like activation hydrogen peroxide (H2O2) at water–iron interface.

“Reactive Mineral Sink” drives soil organic matter dynamics and stabilization

npj Materials Sustainability, Journal Year: 2023, Volume and Issue: 1(1)

Published: Nov. 27, 2023

Abstract Reactive primary and secondary minerals play a critical role in the transformation stabilization of organic matter (OM) soil, aspect that has been largely overlooked existing literature. In this regard, we propose new model known as “reactive mineral sink” (RMS) to illustrate three mechanisms through which these drive bioprocessing, transformation, transport OM soil. Firstly, from biological perspective, reactive influence enzymatic microbial processing binding proteins or influencing structure communities. Secondly, chemical standpoint, have capacity adsorb and/or coprecipitate with it, leading more diverse distribution This distribution, turn, triggers catalysis redox reactions. Thirdly, on physical level, substantial impact soil architecture, aggregate dynamics, porosity development, hydrological processes. These changes then affect transport, reprocessing OM. The RMS provides conceptual framework underscores fundamental driving dynamics carbon (C) sequestration natural Furthermore, it promotes restoration biogeochemical processes ecological resilience. We advocate for implementation strategies based enhance C soils purposes rejuvenating health mitigating CO 2 emission.
