Despite the increasing prevalence of atmospheric nanoplastics (NPs), there remains limited research on their phytotoxicity, foliar absorption, and translocation in plants. In this study, we aimed to fill knowledge gap by investigating physiological effects tomato leaves exposed differently charged NPs absorption NPs. We found that positively caused more pronounced effects, including growth inhibition, increased antioxidant enzyme activity, altered gene expression metabolite composition even significantly changed structure phyllosphere microbial community. Also, exhibited differential translocation, with penetrating into dispersing uniformly within mesophyll cells. Additionally, absorbed were able translocate roots. These findings provide important insights interactions between crop plants demonstrate NPs' accumulation crops could negatively impact agricultural production food safety.

Analysis of aged microplastics: a review

Environmental Chemistry Letters, Год журнала: 2024, Номер 22(4), С. 1861 - 1888

Опубликована: Апрель 4, 2024

Abstract Microplastics are emerging contaminants that undergo progressive aging under environmental conditions such as sunlight irradiation, mechanical forces, temperature variations, and the presence of biological organisms. Since modifies microplastic properties, their own toxicity trapped pollutants, advanced methods to analyze microplastics required. Here we review with focus on process, qualitative identification, quantitative characterization, chemometrics. Qualitative identification is done by techniques, thermal e.g., degradation gas chromatography–mass spectrometry, spectral infrared, Raman, fluorescent, laser techniques. Quantitative characterization microscopy mass spectrometry. Microplastic results in a series surface physical changes, biofilm formation, chemical oxidation, alternation, deterioration. Changes properties allow differentiate aged microplastics. Infrared Raman spectroscopy rapid sensitive for complex samples. Combining two techniques preferable accurate detection categorization.
