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.

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.

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.

Microplastics (MPs) are in all environmental compartments, including atmosphere, terrestrial, and aquatic environments as well marine organisms, foods, drinking water, indoor outdoor environments. MPs can enter the human body through food chain contaminated environment. Ingestion, inhalation, dermal contact routes of their entry into body. Recent studies reporting detection within have raised concern among scientific community knowledge about exposure is still very limited impact on health not well-understood yet. In this review article, we briefly cover reports evidencing MP body, e.g., stool, placenta, lungs, liver, sputum, breast milk, blood. A concise synopsis sample preparation analysis such matrices also provided. This article presents a summary effect cell lines health.

Microplastics are widespread contaminants leading to environmental exposure. While studies on the prevalence in human tissues have multiplied, little is known about their pharmacokinetics. Mechanisms of absorption, distribution, metabolism, and excretion (ADME) must be addressed before effects health (i.e. pharmacodynamics) can understood. Therefore, objective this review was provide an integrated assessment fate microplastics body by gathering information from multiple fields research (e.g. implants microspheres). Absorption mainly occurs through transcytosis enterocytes, while larger particles may internalized gaps persorption) or uptake phagocytes. Only <5 µm reach alveolar region, large found lungs usually result entrapment circulating narrow pulmonary capillary network. Overall, absorption rates expected low. then distributed circulatory system, accumulating respiratory digestive liver, spleen, brain. Metabolism lead biodegradation microplastics, enzymes reactive oxygen species macrophages, exposure physiologic fluids, microbiologic activity gut lumen. Finally, most will removed liver spleen excreted feces. work provides initial attempt at constructing a pharmacokinetics model for further required. Ideally, future works should conducted using histopathology techniques obtain precise location radiolabelled allow tracking time.
