ClearMassBalance Tracing of In Vivo Biodistribution,Relocation, and Excretion of Europium-Doped Micro/Nanoplastics inRats
This rat study used europium-labeled micro- and nanoplastics to track particle distribution in the body after intravenous administration, finding that most accumulated in the liver and spleen with very little reaching the brain or heart. The results suggest that standard biological filtration processes govern microplastic distribution following classical size-dependent rules.
The whole life journey and destination of microplastics: A review
This review traces the full journey of microplastics from their environmental sources through their various pathways into the human body, and what happens once they get inside. Once ingested, microplastics can disrupt gut bacteria, damage the intestinal barrier, and then spread to other organs where they cause inflammation and toxicity. The review highlights significant gaps in our understanding and emphasizes the need for more research on how microplastics move through the body and accumulate over time.
Nano- and microplastics: a comprehensive review on their exposure routes, translocation, and fate in humans
This comprehensive review traces the journey of nano- and microplastics through the human body, covering how they enter through breathing, eating, drinking, and skin contact. Once inside, the smallest particles can cross the gut and lung barriers, enter the bloodstream, and accumulate in organs including the liver, kidneys, and placenta. The review highlights significant knowledge gaps about long-term health effects but notes that the evidence for internal accumulation in humans is growing.
From natural environment to animal tissues: A review of microplastics(nanoplastics) translocation and hazards studies
This review summarizes how micro- and nanoplastics travel from the environment into animal bodies through water, food, air, and even skin contact, then move through the bloodstream to accumulate in organs. Once inside, these particles cause oxidative stress, inflammation, gut damage, reproductive harm, and nervous system effects across many animal species. The findings strongly suggest that similar pathways of exposure and harm could apply to humans.
Penetration of micro/nanoplastics into biological barriers in organisms and associated health effects

A Systematic Review of the Toxicokinetics of Micro- and Nanoplastics in Mammals Following Digestive Exposure
This systematic review summarizes existing research on what happens to micro and nanoplastics after mammals ingest them through food and water. The evidence shows these particles can survive digestion and potentially cross into tissues and organs, raising important questions about long-term health effects from the microplastics we unknowingly consume every day.
The Plastic Within: Microplastics Invading Human Organs and Bodily Fluids Systems
This review documents the presence of microplastics in human organs and body fluids including the liver, blood, heart, placenta, breast milk, lungs, and reproductive tissues. The particles enter through ingestion, inhalation, and skin contact, and may also be introduced through invasive medical procedures. The widespread distribution of microplastics throughout the body raises concerns about their potential effects on organ function and long-term health.
Distribution and translocation of micro- and nanoplastics in fish
This review summarizes research on how micro- and nanoplastics distribute and move through fish bodies, from the gut to organs like the liver, brain, and muscle tissue. Researchers found that nanoplastics are especially concerning because they can cross biological barriers, enter the bloodstream, and even pass to the next generation. The findings highlight the potential for plastic particles consumed by fish to move up the food chain to humans.
Detection of nano- and microplastics in mammalian tissue
Researchers detected nano- and microplastics in mammalian tissue samples using sensitive analytical techniques, confirming particle accumulation in organs beyond the gastrointestinal tract. The findings demonstrate that small plastic particles can translocate from the gut to systemic tissues.
Mass Balance Tracing of In Vivo Biodistribution, Relocation, and Excretion of Europium-Doped Micro/Nanoplastics in Rats
Scientists injected tiny plastic particles into rats and tracked where they went in the body for three months. Most plastic particles collected in the liver and spleen, with smaller particles being harder for the body to get rid of—only 80% of the smallest particles were eliminated compared to just 15% of larger ones. This suggests that microplastics from food, water, and air could build up in our organs over time, though the long-term health effects are still unknown.
Distribution and health impacts of micro- and nanoplastics (MNPs) in human organs: Accumulation, translocation, and toxicity – A systematic review of current evidence
This systematic review summarizes evidence on where micro- and nanoplastics accumulate in the human body. Researchers found these particles in stool, blood, lungs, placenta, and arterial plaques, with polyethylene and polystyrene being the most common types. The findings suggest microplastics can travel through the body and may contribute to inflammation and cardiovascular risk.
Microplastics and human health: Integrating pharmacokinetics
This review takes a pharmacology-based approach to understanding how microplastics move through the human body, covering absorption, distribution, metabolism, and excretion. Evidence suggests that smaller particles (under 10 micrometers) can cross the gut barrier and accumulate in organs like the liver, kidneys, and lungs. Understanding these pathways is essential for determining what levels of microplastic exposure might actually cause harm to human health.
Toxicokinetic Effects of Micro/Nano Plastics on Human Health
