Microplastics have been detected in human stool, lungs, and placentas, which direct exposure to the external environment through various body cavities, including oral/anal cavity uterine/vaginal cavity. Crucial data on microplastic completely enclosed organs are still lacking. Herein, we used a laser infrared chemical imaging system scanning electron microscopy investigate whether microplastics exist heart its surrounding tissues. Microplastic specimens were collected from 15 cardiac surgery patients, 6 pericardia, epicardial adipose tissues, 11 pericardial 3 myocardia, 5 left atrial appendages, 7 pairs of pre- postoperative venous blood samples. not universally present all tissue samples, but nine types found across five with largest measuring 469 μm diameter. Nine also samples maximum diameter 184 μm, type distribution showed alterations following surgical procedure. Moreover, presence poly(methyl methacrylate) appendage, tissue, cannot be attributed accidental during surgery, providing evidence patients undergoing surgery. Further research is needed examine impact introduction potential effects internal health.

Plastics have conveyed great benefits to humanity and made possible some of the most significant advances modern civilization in fields as diverse medicine, electronics, aerospace, construction, food packaging, sports. It is now clear, however, that plastics are also responsible for harms human health, economy, earth's environment. These occur at every stage plastic life cycle, from extraction coal, oil, gas its main feedstocks through ultimate disposal into The extent these not been systematically assessed, their magnitude fully quantified, economic costs comprehensively counted.The goals this Minderoo-Monaco Commission on Human Health examine plastics' impacts across cycle on: (1) health well-being; (2) global environment, especially ocean; (3) economy; (4) vulnerable populations-the poor, minorities, world's children.

Environment & Health, Год журнала: 2023, Номер 1(4), С. 249 - 257

Опубликована: Авг. 10, 2023

Microplastics are ubiquitous in the global environment. As a typical emerging pollutant, its potential health hazards have been widely concerning. In this brief paper, we introduce source, identification, toxicity, and hazard of microplastics human. The literature review shows that frequently detected environmental human samples. Humans potentially exposed to through oral intake, inhalation, skin contact. We summarize toxic effects experimental models like cells, organoids, animals. These consist oxidative stress, DNA damage, organ dysfunction, metabolic disorder, immune response, neurotoxicity, as well reproductive developmental toxicity. addition, epidemiological evidence suggests variety chronic diseases may be related exposure. Finally, put forward gaps toxicity research their future development directions. This will helpful understanding exposure risk microplastics.

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.

First Evidence of Microplastics in Human Urine, a Preliminary Study of Intake in the Human Body

Toxics, Год журнала: 2022, Номер 11(1), С. 40 - 40

The ubiquitous presence of microplastics (MPs) and their health effects is a recent scientific topic. However, the investigation MPs in human/biological matrices has several limitations due to analytical methods sample treatment protocols. In this study, urine samples six volunteers from different cities south Italy (three men three women) was investigated by Raman microspectroscopy. analysis pinpointed four pigmented microplastic fragments (4-15 μm size), with irregular shapes, which were characterized terms morphology chemical composition. Polyethylene vinyl acetate (PVA), polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE) found (PVA PVC one female PP PE male samples). This preliminary study suggests that could pass through gastrointestinal tract are eliminated biological processes.

Human uptake abundance of microplastics via various pathways, and they accumulate in human liver, kidney, gut even placenta (especially with a diameter 1 μm or less). Recent scientific studies have found that exposure to causes intestinal inflammation liver metabolic disorder, but it remains largely unknown whether the damage may cause further development severe diseases. In this study, we discovered one such potential diseases be induced by small-sized (with μm) performing multi-organ multi-omics study comprising metabolomics microbiome approaches. Unlike other animal experiments, dosing strategy was applied mice according daily highly exposed population, which more environmentally relevant reflective real-world exposure. Our on gut-liver axis metabolism shown crosstalk between ultimately leaded insulin resistance diabetes. We proactively verified hypothesis measuring levels fasting blood glucose insulin, were significantly elevated These results indicate urgent need large-scale cohort evaluation epidemiology prognosis after future.
