Microplastic/Nanoplastic Particles and their Accumulation in the Human Body or Mammalian Model Organisms and Effect on Health
AI summary Read the abstract
This review of 37 studies found that tiny plastic particles—especially the smallest ones, called nanoplastics—can get into our bodies through food, air, and even skin, and have been detected in blood, lungs, liver, and brain tissue. Once inside, these particles seem to trigger inflammation, cell damage, and disrupted metabolism, though scientists haven't yet proven they directly cause disease in humans. The bottom line: while we don't have to panic, this is a strong signal that long-term plastic exposure deserves serious attention and more research, since it may pose real risks to our health over time.
Mikro- ir nanoplastikai (MNP) tapo plačiai paplitusiais aplinkos teršalais, kurių svarba žmonių sveikatai didėja. Šios literatūros apžvalgos tikslas buvo išanalizuoti naujausius mokslinius įrodymus apie MNP kaupimąsi širdies ir kraujagyslių, kvėpavimo, virškinimo ir nervų sistemose, taip pat apie jų galimą toksinį poveikį žmonėms ir žinduolių modeliniams organizmams. Apžvalgos tikslas buvo vadovautis PRISMA gairėmis ir naudoti „PubMed“ kaip pagrindinę duomenų bazę. Moksliniai straipsniai, paskelbti 2020–2026 m., buvo atrinkti pagal iš anksto nustatytus įtraukimo ir neįtraukimo kriterijus, todėl į galutinę analizę buvo įtraukti 37 tyrimai. Įrodymai rodo, kad MNP į organizmą patenka daugiausia nurijus ir įkvėpus, o antrinis patekimo per odą kelias yra perėjimas. Mažesnės dalelės, ypač nanoplastikai, pasižymi didesniu biologiniu prieinamumu ir gebėjimu kirsti biologinius barjerus, įskaitant hematoencefalinį barjerą. MNP buvo aptiktos kraujyje, plaučių audinyje, kraujagyslių struktūrose, kepenyse ir smegenų audinyje, o tai rodo sisteminį pasiskirstymą ir kaupimąsi. Praneštas biologinis poveikis apima oksidacinį stresą, uždegimą, imuninės sistemos sutrikimus, mitochondrijų disfunkciją, fibrozę ir medžiagų apykaitos sutrikimus. Nors tiesioginiai priežastiniai ryšiai žmonėms vis dar nepakankamai nustatyti, dabartiniai duomenys rodo, kad lėtinis MNP poveikis gali kelti didelę ilgalaikę riziką sveikatai, todėl reikia skubiai atlikti tolesnius tyrimus ir standartizuotas metodikas.

Microplastics and Nanoplastics in the Human Diet: Sources of Exposure, Bioavailability, Toxicokinetics, and Systemic Health Effects
AI summary Read the abstract
Tiny plastic particles from food, water, and packaging can enter your body, and the smallest ones may slip past your gut lining into your bloodstream and organs. This review of existing lab and animal studies found these particles are linked to cell damage, inflammation, and disruptions in hormones and organ function, but scientists still don't have solid proof that this causes actual diseases in humans. Bottom line: the concern is real and worth taking seriously, but we need much better human studies before drawing firm conclusions about health risks.
Microplastics and Nanoplastics in Human Health: From Environmental Contaminants to Internal Pollutants—A Comprehensive Review of Exposure, Bioaccumulation, Toxicity Mechanisms, and Emerging Detection Technologies
AI summary Read the abstract
This review pulls together research showing that tiny plastic particles from our food, water, and air aren't just polluting the environment—they're building up inside our bodies, showing up in blood, lungs, brain tissue, and even breast milk. Early studies hint at possible links to heart problems and brain inflammation, but scientists stress this connection isn't proven yet and more long-term research is needed. The bigger takeaway: better detection tools are helping us find these particles in the body, which is the first step toward understanding whether—and how much—they actually harm our health.
Human Exposure to Nanoplastics and Its Toxicological and Environmental Implications
AI summary Read the abstract
Tiny plastic particles called nanoplastics are everywhere—in our water, air, and food—and this review pulls together existing research on how they get into our bodies (through eating, breathing, or even skin contact) and spread to different organs. The science suggests these particles may trigger cell damage, inflammation, hormone disruption, and other harmful effects, though researchers note it's still hard to measure exact exposure levels and long-term risks. The takeaway: nanoplastic pollution is a growing health concern worth watching, but scientists still need better tools to figure out exactly how much harm it's causing.
Human Exposure to Micro- and Nanoplastics: Trans -Barrier Transport, Tissue Accumulation, and Health Risks
AI summary Read the abstract
Tiny plastic particles called micro- and nanoplastics are turning up in human bodies more than we realized—including surprisingly high amounts in brain tissue—and this review pulls together existing research showing they can enter through food, air, and skin, then slip past the body's natural defenses (like the blood-brain barrier and placenta) to build up in organs. While scientists are still working out exactly how harmful this is long-term, early studies link these particles to various toxic effects, which is why researchers are calling for better detection tools and more research into low-dose, everyday exposure. The bottom line: plastic pollution isn't just an environmental probl
Microplastics in the Human Body
AI summary Read the abstract
Tiny plastic particles called microplastics get into our bodies through the food we eat, the air we breathe, and even through our skin—and this review of a decade of research shows they've been found in our blood, lungs, reproductive organs, and even the placentas of pregnant women. Scientists are concerned because these particles may trigger cell damage, immune problems, and hormone disruption, though more research is needed to fully understand the risks. The good news: researchers are exploring solutions, from better regulations to new technologies that break down plastic waste before it becomes a problem.
