ClearA review on microplastics and nanoplastics in the environment: Their occurrence, exposure routes, toxic studies, and potential effects on human health
This review summarizes what is known about how microplastics and nanoplastics enter the human body through food, air, and skin contact, and what they do once inside. Studies on cells and animals show these tiny particles can cause oxidative stress, DNA damage, inflammation, and harm to the immune, digestive, reproductive, and nervous systems. The research makes clear that microplastics are not just an environmental problem but a direct concern for human health.

Mechanistic insight into potential toxic effects of microplastics and nanoplastics on human health
This review summarizes how microplastics and nanoplastics enter the body through breathing, eating, and skin contact, then travel through the bloodstream to deposit in organs. Studies show they can cause oxidative stress, inflammation, immune dysfunction, genetic damage, developmental abnormalities, and potentially cancer, though most evidence comes from cell and animal studies rather than human research.
Recent advances in toxicological research and potential health impact of microplastics and nanoplastics in vivo
This review summarizes the growing body of research on how micro- and nanoplastics affect living organisms, covering impacts from physical tissue damage and gut disruption to reproductive harm and immune system interference. Researchers found that these tiny particles can also act as carriers for heavy metals, toxic chemicals, and pathogens, potentially amplifying their harmful effects. The evidence indicates that microplastics may move up the food chain and ultimately reach humans, though the full extent of health risks remains under investigation.
Micro-plastics: An invisible danger to human health
This review examined microplastics as invisible but pervasive threats to human health, summarizing exposure routes via air, water, and food, and reviewing evidence from animal studies linking microplastic exposure to inflammation, oxidative stress, endocrine disruption, and reproductive harm, while calling for urgent human epidemiological research.
Human Exposure to Microplastics and Its Associated Health Risks
This review examines how microplastics enter the human body through food, air, and skin, and have been detected in stool, blood, and tissues. Research in lab animals and human cells shows that microplastics can disrupt digestion, immunity, the nervous system, and reproduction, and can also amplify the toxicity of other environmental pollutants they carry.
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.
A comprehensive review on the source, ingestion route, attachment and toxicity of microplastics/nanoplastics in human systems
This review summarizes how microplastics and nanoplastics enter the human body through eating, breathing, and skin contact, then spread to organs throughout all nine major body systems. The particles cause harm mainly through oxidative stress, inflammation, and disrupted metabolism, with the digestive and respiratory systems being most affected since they are the primary entry points.
