Introduction Soil organic matter plays an important role in the long-term “locking” of contaminants soil environment. Recently, microbial-derived have been recognized as essential components stabilized carbon pools. However, contribution to sorption remains unclear. Methods Here, we obtained matter-mineral composites by inoculating model (a mixture hematite and quartz sand (FQ) or montmorillonite (MQ)) with natural microorganisms different substrate-carbon (glycine (G), glucose (P), 2, 6-Dimethoxyphenol (B)), which were named GF, PF, BF, GM, BM, PM, respectively. Batch sorption/desorption experiments conducted for phenanthrene (PHE) ofloxacin (OFL) on composites. Results Discussion The cultured 2,6-dimethoxyphenol had highest content (0.98% FQ 2.11% MQ) three substrates. incubated MQ (0.64%–2.11%) was higher than that (0.24%–0.98%), indicating facilitated accumulation owing its large specific surface area. PHE mainly dominated hydrophobic partitioning π-π conjugation, whereas OFL hydrogen bonding conjugation. onto more stable PHE. Microbial-derived -mineral can reduce risk contaminant migration soil, particularly ionic contaminants.

Iron in soil exists various valence states and is prone to changes with alterations environmental conditions. Its migration transformation are crucial for formation understanding evolution. This study focuses on Quaternary red soils found woodland, sparse forest grassland, cultivated land located the semi-humid region of middle temperate zone. For comparison, buried was also examined. A reconstruction model used quantitatively calculate variation different forms iron order analyze composition, migration, within profile, as well evolutionary traits influenced by diverse use activities. that after exposure use, from topsoil migrated subsoil, altering distribution. Free crystalline oxides decreased but increased specific subsoil layers, woodland grassland showing most significant changes. Silicate-bound pooled weathered form free under uses, poorly transformed into oxides, exhibiting highest intensity. Conversion processes predominated over soils. The evolution can be divided three stages, marked composition crystallization due anthropogenic Initially, during 140−94 ka BP, stable. Then, between 94–24 plant decomposition formed iron–metal complexes, releasing crystallizing oxides. Finally, 24 BP present, activities intensified, increasing conversion rates these quantifies soils, providing insights sustainable management, especially regions where human have accelerated Based findings, following policy recommendations proposed: implement practices, encourage management strategies preserve natural vegetation, promote research techniques, develop regulatory policies, support educational programs maintain health stability particularly
