Twenty years of microplastics pollution research—what have we learned?

Science, Год журнала: 2024, Номер 386(6720)

Опубликована: Сен. 19, 2024

Twenty years after the first publication that used term microplastic, we review current understanding, refine definitions, and consider future prospects. Microplastics arise from multiple sources, including tires, textiles, cosmetics, paint, fragmentation of larger items. They are widely distributed throughout natural environment, with evidence harm at levels biological organization. pervasive in food drink have been detected human body, emerging negative effects. Environmental contamination could double by 2040, wide-scale has predicted. Public concern is increasing, diverse measures to address microplastic pollution being considered international negotiations. Clear on efficacy potential solutions now needed issue minimize risks unintended consequences.

Micro(nano)plastics sources, fate, and effects: What we know after ten years of research

Journal of Hazardous Materials Advances, Год журнала: 2022, Номер 6, С. 100057 - 100057

The last decade has been transformative for micro(nano)plastic (MnP) research with recent discoveries revealing the extent and magnitude of MnP pollution, even in world's most remote places. Historically, while researchers recognized that plastic pollution was derived from land-based sources, it generally believed microplastic particles (i.e., fragments <5 mm) only a marine issue effects largely impacting biota. However, over progressed rapidly MnPs freshwater, snow, ice, soil, terrestrial biota, air found ocean spray. have now every environmental compartment on earth, within tissues gastrointestinal tracts thousands species, including humans, resulting harmful effects. 10 years also seen development new techniques analysis, re-purposing old technologies allowing us to determine down nano size range (<1 µm). This short review summarizes what key milestones major advances made nanoplastic environment, their fate, decade.

Microplastics contamination in food and beverages: Direct exposure to humans

Journal of Food Science, Год журнала: 2021, Номер 86(7), С. 2816 - 2837

Опубликована: Июнь 19, 2021

Since microplastics (MPs) bring the potential risks to human health when plastics are ingested, more needs be known about presence and abundance of ingestion MPs. To address these issues, we reviewed 108 publications in Web Science concerning abundances, sources, analytical methods MPs daily intake including fish, salt, drinking water, beverages, package food, other food. The results demonstrate that aquatic food products (fish bivalves) present a wide range 0-10.5 items/g for bivalves 0-20 items/individual fish. Salt data literatures concentration 0-13,629 particles/kg. Drinking water is also pathway exposure human, presenting from 0 61 particles/L tap 6292 MPs/L bottled water. Besides, have been found sugar, honey, vegetables, fruits. Therefore, via nonnegligible route.

Characterizing the multidimensionality of microplastics across environmental compartments

Water Research, Год журнала: 2021, Номер 202, С. 117429 - 117429

Опубликована: Июль 14, 2021

Understanding the multidimensionality of microplastics is essential for a realistic assessment risks these particles pose to environment and human health. Here, we capture size, shape, area, polymer, volume mass characteristics >60,000 individual microplastic as continuous distributions. Particles originate from samples taken different aquatic compartments, including surface water sediments marine freshwater environment, waste effluents, organisms. Data were obtained using state-of-the-art FTIR-imaging, same automated imaging post-processing software. We introduce workflow with two quality criteria that assure minimum data loss due volumetric filter area subsampling. find probability density functions (PDFs) particle length follow power law distributions, median slopes ranging 2.2 3.1 biota samples, compartment-specific. Polymer-specific PDFs demonstrated significant differences in among polymers, hinting at polymer specific sources, removal or fragmentation processes. Furthermore, provide width, width ratio, distributions propose how can represent full diversity toxicologically relevant dose metrics required risks.

Micro- and Nanoplastics Breach the Blood–Brain Barrier (BBB): Biomolecular Corona’s Role Revealed

Nanomaterials, Год журнала: 2023, Номер 13(8), С. 1404 - 1404

Опубликована: Апрель 19, 2023

Humans are continuously exposed to polymeric materials such as in textiles, car tires and packaging. Unfortunately, their break down products pollute our environment, leading widespread contamination with micro- nanoplastics (MNPs). The blood–brain barrier (BBB) is an important biological that protects the brain from harmful substances. In study we performed short term uptake studies mice orally administered polystyrene micro-/nanoparticles (9.55 µm, 1.14 0.293 µm). We show nanometer sized particles—but not bigger particles—reach within only 2 h after gavage. To understand transport mechanism, coarse-grained molecular dynamics simulations on interaction of DOPC bilayers a nanoparticle presence absence various coronae. found composition biomolecular corona surrounding plastic particles was critical for passage through BBB. Cholesterol molecules enhanced these contaminants into membrane BBB, whereas protein model inhibited it. These opposing effects could explain passive brain.

The Science of The Total Environment, Год журнала: 2022, Номер 851, С. 158111 - 158111

Опубликована: Авг. 17, 2022

This systematic review aims to summarize the current knowledge on biological effects of micro- and nanoplastics (MNPs) human health based mammalian systems. An extensive search literature led a total 133 primary research articles relevance MNPs. Our findings revealed that although study MNP cytotoxicity inflammatory response represents major theme, most studies (105 articles) focused polystyrene MNPs due their wide availability as well characterised material can be manufactured with large range particle sizes, fluorescence labelling various surface modifications. Among covered in this review, 117 reported adverse after being exposed Mammalian vitro identified multiple including cytotoxicity, oxidative stress, response, genotoxicity, embryotoxicity, hepatotoxicity, neurotoxicity, renal toxicity even carcinogenicity, while rodent vivo models confirmed bioaccumulation liver, spleen, kidney, brain, lung gut, presenting at different levels reproductive toxic trans-generational toxicity. In contrast, remaining 16 indicated an insignificant impact humans. A few attempted investigate mechanisms or factors driving several determining size, concentration, shape, charge, attached pollutants weathering process, which, however, were not benchmarked considered by studies. demonstrates there are still many inconsistencies evaluation potential lack comparability between Current limitations hindering attainment reproducible conclusions recommendations for future directions also presented.
