Micro- and nanoplastics (MNPs) are attracting increasing attention due to their persistence potential ecological risks. This review critically summarizes the effects of photo-oxidation on physical, chemical, biological behaviors MNPs in aquatic terrestrial environments. The core this paper explores how photo-oxidation-induced surface property changes affect adsorption toward contaminants, stability mobility water porous media, as well transport pollutants such organic (OPs) heavy metals (HMs). It then reviews photochemical processes with coexisting constituents, highlighting critical factors affecting MNPs, contribution phototransformation other contaminants. distinct mechanism aged pointed out, terms toxicity organisms, biofilm formation, planktonic microbial growth, soil sediment community function.

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.

High-Resolution Mass Spectrometry Combined with Reactive Oxygen Species Reveals Differences in Photoreactivity of Dissolved Organic Matter from Microplastic Sources in Aqueous Environments

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(23), P. 10334 - 10346

Published: May 28, 2024

Microplastics (MPs)-derived dissolved organic matter (MPs-DOM) is becoming a non-negligible source of DOM pools in aquatic systems, but there limited understanding about the photoreactivity different MPs-DOM. Herein, MPs-DOM from polystyrene (PS), polyethylene terephthalate (PET), poly(butylene adipate-co-terephthalate) (PBAT), PE, and polypropylene (PP), representing aromatic, biodegradable, aliphatic plastics, were prepared to examine their photoreactivity. Spectral high-resolution mass spectrometry analyses revealed that PS/PET/PBAT-DOM contained more unsaturated aromatic components, whereas PE/PP-DOM was richer saturated components. Photodegradation experiments observed molecules prone be degraded compared molecules, leading higher degradation than PE/PP-DOM. mainly by hydroxyl (•OH) via attacking structures, singlet oxygen (1O2) through oxidizing side chains. The [•OH]ss 1.21–1.60 × 10–4 M 0.97–1.14 PE/PP-DOM, while [1O2]ss 0.90–1.35 10–12 0.33–0.44 M, respectively. This contributes stronger with degree photodegradation reflected decreasing tendency aromatic-unsaturated aliphatic-saturated molecules. Special attention should paid environmental impacts associated containing highly compounds.

Key Role of Vegetation Cover in Alleviating Microplastic-Enhanced Carbon Emissions

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 6, 2024

Microplastics (MPs) are considered to influence fundamental biogeochemical processes, but the effects of plant residue-MP interactions on soil carbon turnover in urban greenspaces virtually unknown. Here, an 84-day incubation experiment was constructed using four types single-vegetation-covered soils (6 years), showing that polystyrene MP (PSMP) pollution caused unexpectedly large increase CO2 emissions. The additional originating from highly bioavailable active dissolved organic matter molecules (<380 °C, predominantly polysaccharides) converted persistent (380–650 aromatic compounds) rather than PSMP derivatives. However, priming effect derivatives weakened plant-driven (resistivity: shrub > tree grass). This can be explained two perspectives: (1) Plant residue-driven humification processes reduced percentage derived PSMPs. (2) residues accelerated bacterial community succession (dominated by residue types) slowed fungal demise (retained turnover-related functional taxa), enabling specific enrichment glycolysis, citric acid cycle and pentose phosphate pathway. These results provide a necessary theoretical basis understand role reducing harm at ecological level refresh knowledge about importance biodiversity for ecosystem stability.
