Microplastic-derived dissolved organic matter and its biogeochemical behaviors in aquatic environments: A review

Critical Reviews in Environmental Science and Technology, Journal Year: 2024, Volume and Issue: 54(11), P. 865 - 882

Published: Jan. 19, 2024

Microplastic-derived dissolved organic matter (MP-DOM) exerts great effects on carbon pool and its environmental behaviors in natural waters due to increasing amounts of uncontrolled plastic disposal. However, systematic understanding chemical composition impacts MP-DOM aquatic systems was limited. In this work, the molecular structures derived from diverse characterization methods were examined synthesized provide a basis for their processes. Additionally, those factors affecting quantity quality released (e.g., types, water environments, external weathering conditions) reviewed. Furthermore, including biological degradation, adsorption mineral surfaces, interaction with pollutants, as well comprehensively summarized. Finally, we outlooked future research directions studies, aiming contribute deeper mechanisms control pollution through analysis MP-DOM. This review provides information further impact microplastics water, which might have consequences fluxes biogeochemical metal contaminants.

Characterization of microplastic-derived dissolved organic matter in freshwater: Effects of light irradiation and polymer types

Environment International, Journal Year: 2024, Volume and Issue: 185, P. 108536 - 108536

Published: March 1, 2024

This study investigated the impacts of light irradiation and polymer types on leaching behavior dissolved organic matter (DOM) from microplastics (MPs) in freshwater. Polypropylene had highest capacity DOM after photoaging, followed by polystyrene (PS), polyamide (PA) polyethylene terephthalate (PET). While similarly low levels were observed remaining 5 MP suspensions under UV almost all (except PA) darkness. These suggest that photooxidation some buoyant plastics may influence carbon cycling nature waters. Among 9 MP-derived leachates, PET leachates chromophoric concentration aromaticity, probably owing to special benzene rings carbonyl groups structures its fast degradation rate. Protein-like substances primary fluorescent PS), especially darkness no other found. Considering bio-labile properties proteins together, MPs regardless floating or suspended an aquatic environment have prevalent long-term effects microbial activities. Besides, monomers hexamers with newly formed chemical bonds identified UV-irradiated suspensions. results will contribute a deep insight into potential ecological related degradation.

Microplastics (MPs) degradation due to light radiation, weathering, water erosion and biodegradation might change MPs physical chemical characteristics thereby behaviors in natural environments. This study conducted a comparison investigation on polyvinyl chloride (PVC), polyethylene (PE) polyamide (PA) three different environmental conditions, namely simulated UV light, body. The results showed that of environments is more complex than the case controlled experimental condition (such as light). In conditions body, are easily covered by sediments/microorganisms.
