20.500.12556/DiRROS-29282 When "biodegradable" is not benign: Microplastic-driven disruption of soil processes and plant-microbe interactions The increasing use of biodegradable plastics (BPs) as alternatives to conventional plastics (CPs) is leading to the accumulation of biodegradable microplastics (BMPs) in terrestrial environments. Contrary to assumptions of rapid degradation, BMPs can persist in soil long enough to interact with key biological processes. This review advances the field by proposing a mechanistic framework linking BMP aging and degradation, soil physicochemical transformations, plastisphere assembly, rhizosphere interactions, and plant responses, and by critically evaluating the sources of inconsistency across studies. We show that divergent effects of BMPs can be best explained by four interacting determinants: polymer chemistry and additive composition, aging-driven surface transformations, soil physicochemical properties, and rhizosphere processes including plant-mediated effects. Through these coupled pathways, BMPs can alter aggregation, pore architecture, pH, enzyme activity, and carbon and nutrient cycling, thereby reshaping the soil environment in which microorganisms and roots interact. BMP surfaces can also act as dynamic microbial niches that promote biofilm formation, shift microbial community composition and function, and under certain conditions may facilitate pollutant transport, pathogen persistence, and horizontal gene transfer. Plant responses to BMPs are predominantly indirect and emerge from rhizosphere-mediated processes, which helps explain the wide variability in reported plant responses, ranging from subtle metabolic changes to pronounced growth inhibition. However, current evidence is constrained by short-term studies and insufficient consideration of aged materials. Biodegradability should therefore not be equated with low ecological risk in soils. Progress in this field requires integrative approaches linking BMP properties, plastisphere dynamics, and plant–soil interactions over time. soil ecosystem biodegradable microplastics plant microbiome plastisphere rhizosphere nutrient cycling talni ekosistem biološko razgradljiva mikroplastika rastlinski mikrobiom plastisfera rizosfera kroženje hranil true false true Angleški jezik Slovenski jezik Neznano 2026-05-06 09:45:05 2026-05-06 09:45:06 2026-05-07 03:51:12 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Soavtorji: Anita Jemec Kokalj, Marjana Regvar, Marina Dermastia, Katarina Vogel-Mikuš; Opis vira z dne 3. 12. 2024; str. 1-18 Vol. 510, [article no.] 142138 Jun. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-06-01 574:579 1873-3336 10.1016/j.jhazmat.2026.142138 276138755 https://www.sciencedirect.com/science/article/pii/S0304389426011167?via%3Dihub 1 80e24942-491f-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43827 RAZ_Pelko_Teja_2026.pdf RAZ_Pelko_Teja_2026.pdf 1 95250949C30D0A09255A7BF0C977A2D5 bb8444f46ff6b4148b226ba71920ac352ad7ae7ec31250b5c2aa232e3ff2b31b 485124d4-4925-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43831 Nacionalni inštitut za biologijo 0 0 0
