The pervasive dispersion of micro/nanoplastics in various environmental matrices has raised concerns regarding their potential intrusion into terrestrial ecosystems and, notably, plants. In this comprehensive review, we focus on the interaction between these minute plastic particles and We delve current methodologies available for detecting plant tissues, assess accumulation distribution within roots, stems, leaves, elucidate specific uptake transport mechanisms, including endocytosis, apoplastic transport, crack-entry mode, stomatal entry. Moreover, are complex processes influenced by multiple factors, particle size, surface charge, mechanical properties, physiological characteristics plants, as well external conditions. conclusion, review paper provided valuable insights understanding highlighting complexity multitude factors that can influence them.

The accumulation of microplastics poses potential risks to soil health. Here, we did a preliminary exploration on the Lumbricus terrestris (Oligochaeta) reduce low-density polyethylene (LDPE), polylactic acid (PLA), and polybutylene adipate terephthalate (PBAT) microplastic (20–648 µm) contamination in soils. ingestion microplastics-contaminated (1% microplastics, dw/dw) mesocosm system pure Petri Dish by earthworms were studied. Results show that survived (0% mortality 35 days) but barely when exposed solely (30–80% 4 days). Size-dependent was not observed. fragmentation LDPE gizzard facilitated confirmed significantly increased ratio small-sized (20–113 from bulk gut (from 8.4% 18.8%). PLA PBAT fragmented without facilitation soil, ratios 55.5% 108.2% higher than respective pristine distributions. Substantial depolymerization (weight-average molar mass reduced 17.7% with shift molecular weight distribution) suspected observed worm gut, while no change for buried 49 days. Our results suggest ingested could undergo (for certain polymers) earthworm gut. Further research is needed reveal mechanisms polymer evaluate feasibility bioremediation earthworms.

A systematic review of the impacts of exposure to micro- and nano-plastics on human tissue accumulation and health

Eco-Environment & Health, Год журнала: 2023, Номер 2(4), С. 195 - 207

Опубликована: Авг. 21, 2023

Micro- and nano-plastics (MNPs) pollution has become a pressing global environmental issue, with growing concerns regarding its impact on human health. However, evidence the effects of MNPs health remains limited. This paper reviews three routes exposure to MNPs, which include ingestion, inhalation, dermal contact. It further discusses potential translocation in lungs, intestines, skin, analyses homeostasis organ systems, provides an outlook future research priorities for There is that are present tissues or fluids.

Toxicity Mechanisms of Nanoplastics on Crop Growth, Interference of Phyllosphere Microbes, and Evidence for Foliar Penetration and Translocation

Environmental Science & Technology, Год журнала: 2023, Номер 58(2), С. 1010 - 1021

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.

Large-scale production, rapid consumption, insufficient recovery and management, slow degradation lead to a large accumulation of plastic waste microplastics. Microplastics are characterized as stable, small, having specific surface area strong hydrophobicity. They carriers many hydrophobic organic pollutants, heavy metals, pathogenic bacteria drug resistance genes. Worldwide, microplastic pollution in soils has attracted much attention. The progress perspectives the separation detection soil microplastics deserve comprehensive review discussion.

The ever-increasing emission plastic waste makes it understand ecology and associated effects. Here, we present global fingerprint plastisphere, analyzing samples collected freshwater, seawater, terrestrial ecosystems. community has clearly higher heterogeneity more deterministically dominated assembly compared habitats. New patterns—loose fragile networks with mostly specialist linkages among microorganisms rarely found habitats—are seen Plastisphere microbiomes generally have great potential metabolize organic compounds, which could accelerate carbon turnover. Microorganisms involved nitrogen cycle also altered especially freshwater plastispheres, where high abundance denitrifiers may increase release nitrite (aquatic toxicant) nitrous oxide (greenhouse gas).
