Microplastics are ubiquitously distributed and persistently present in soil-water systems, posing potential ecological health risks worldwide. Free radicals highly reactive particularly at soil-water-air interface. The dynamic changes of free sensitive to environmental conditions may greatly impact the fate microplastics. However, pathways, reaction kinetics, or transformation products microplastic degradation by systems remains unclear. Climate change alters physical chemical environment this can directly affect microplastics, indirectly influence it altering generation species radicals. Here, we summarized analyzed fluctuations (such as superoxide radicals, hydrogen peroxide, peroxyl hydroxyl radicals) on microplastics their derivants. We also discussed how driven climate By integrating aspects such change, radical chemistry, pollution, work delineates critical issues pollution exacerbated condition changes. In response existing challenges deficiencies current research, feasible countermeasures proposed. This offers valuable insights for future research predicting controlling ecotoxicity caused associated with global change.

ABSTRACT Rationale It has been demonstrated that microplastics and nanoplastics (MNPs) can be found in soil MNPs taken up by plants. In order to conduct a risk assessment for human consumption, it is necessary have an estimate of the mass concentration plastics crops. A new thermal extraction desorption coupled with gas chromatography spectrometry (TED‐GC/MS) method developed analysis polystyrene (PS) pak choi. Methods this study, thermogravimetric analyser (TGA) equipped absorption unit (TAU), was GC system (TDU2), (5%‐phenyl)‐methylpolysiloxane column GC/MSD single quadrupole spectrometer. The systems were connected via MultiPurposeSampler (MPS). Samples pyrolyzed TGA; pyrolysis products trapped on PDMS polymer bar, desorbed TDU, separated analysed GC/MS system. Results purpose study investigate qualitative quantitative detection PS determined limit (LOD) 0.09 μg, quantification (LOQ) 0.28 μg absolute. Plants treated 100 nm particles 19.0 ± 6.7 μg/g DM plants 500 64.1 8.6 found. Conclusions This first use TED‐GC/MS different sizes choi thus provides important basis determination vegetables.

Micro- and nanoplastic particles (MNPPs) are emerging pollutants with significant environmental impacts due to their persistence, increasing concentrations, potential health risks. Most MNPP studies have focused on identifying, quantifying, assessing ecotoxicological in water or soil. However, the atmosphere is crucial transporting chemically transforming MNPPs. Further, well-established aerosol particle characterization techniques underutilized inconsistently applied existing atmospheric studies. This perspective synthesizes literature addresses future research needs unique MNPPs, highlighting need bridge microplastics communities better understand sources, chemical transformations, transport mechanisms, as well effects ecological impacts, which differ from those soil water. Advancing these areas requires standardized methods a multidisciplinary approach comprehensively assess interactions across compartments, providing essential insights into fate

Abstract Microplastics pollution is a widely recognized issue, although significant analytical challenges remain to be overcome in order achieve more comprehensive ecological understanding. The complex nature of this pollutant, with its variable physical and chemical properties, presents considerable when it comes establishing standardized methods for studying it. One crucial factor that influences toxicity particle size, yet even parameter lacks well-established framework, especially the case nanoplastics. Although size range limits are already proposed literature, where most acceptable values microplastics from 1 5,000 μm nanoplastics 1,000 nm, we propose narrowing these 0.1–1,000 10–100 respectively. We based our discussion on conceptual terminology, polymer structure toxicity, highlighting significance accurately defining their range. standardization will allow development efficient approaches enabling understanding consequences potential risks.

Abstract The excessive production and use of plastics increase the release micro‐ nanoplastics (MNPs) into environment. In recent years, research has focused on occurrence MNPs in air, soil water. Nevertheless, there is still a lack knowledge regarding plants. To determine load, translocation their effects metabolism, pak choi, tomato, radish asparagus have been exposed with fluorescent‐labelled poly(methyl methacrylate) or polystyrene (PS) MNPs. entry nanoparticles (NPs) various sizes (100–500 nm) surface modifications (unmodified, COOH NH 2 ) plants demonstrated using confocal laser scanning microscopy (CLSM). translocalization from root to shoot accumulation NP intercellular spaces were regardless modification. addition, metabolomics was used evaluate metabolic changes induced by choi.
