Impact of micro-nano plastics in daily life on human health: toxicological evaluation from the perspective of normal tissue cells and organoids
AI summary Read the abstract
This review found that micro- and nanoplastics are present in nearly all everyday products, including food, drinks, and household items, and can enter the human body through the digestive tract, respiratory system, and body fluids. Lab studies on human cells and organoids show these tiny particles cause measurable cell damage and genetic changes, even at concentrations similar to normal environmental exposure. The findings highlight the need for long-term health monitoring, especially since these particles can transfer from a mother's placenta to her unborn child.
Plastics are the most frequently used materials in people's daily life, and the primary and secondary microplastics generated from them may harm the health of adults. This paper focuses on the summary of the existence of microplastics in many objects most closely related to people in daily life, the toxicological influences it causes in cultured human normal cells and organoids, and the prospects for future research directions. Micro- and nano-plastics (MNPs) are found in almost all of our everyday products, such as food, drink, and daily necessities, etc. It can enter the digestive tract, respiratory system, and body fluids of the human body, and at lower or equal environment concentrations exhibits obvious cytotoxicity and genotoxicity toward cells and organoids, probably becoming a kind of toxin affecting human health. In addition, due to MNPs can be transferred from the placenta to the embryo, long-term growth-tracking studies of newborns should be done vitally. Besides, due to their wide usability in daily products and the ability to penetrate cytomembranes, the toxicological effects of polyethylene and polypropylene nanoplastic particles equal to or lower than environmental (normal exposure to human body) concentrations are recommended to be studied on human health in the future. Finally, for those individuals who carry MNPs, long-term health evaluation must be performed.

The impact of microplastics and nanoplastics on human health: a growing concern
AI summary Read the abstract
Tiny plastic particles—so small they can enter your body through the food you eat, the air you breathe, and even your skin—have become impossible to avoid, and this review pulls together existing research on what that means for your health. Scientists have found these particles can travel from your gut, lungs, and skin into your bloodstream, reaching organs throughout your body and even crossing into the placenta during pregnancy, where they may disrupt hormones, trigger inflammation, and cause cellular damage. While researchers are still working out exactly how harmful this is, the mounting evidence is a strong signal that reducing plastic exposure and pollution deser
A review on microplastics and nanoplastics in the environment: Their occurrence, exposure routes, toxic studies, and potential effects on human health
AI summary Read the abstract
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.
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.
Microplastics and Nanoplastics in Health Concerning Cellular Toxicity Mechanisms, Exposure Pathways, and Global Mitigation Strategies
AI summary Read the abstract
This review synthesizes current knowledge on how micro- and nanoplastics cause cellular damage in the human body, covering mechanisms like oxidative stress, inflammation, DNA damage, and disruption of cell signaling pathways. Researchers note that exposure occurs through multiple routes including ingestion and inhalation, allowing particles to reach organs throughout the body. The study highlights significant gaps in understanding long-term and low-dose exposure effects that are most relevant to everyday human contact with these particles.

AI summary Read the abstract
This review summarizes current evidence on how micro- and nanoplastics enter the human body through food, air, and skin contact, and the cellular damage they may cause. While microplastic pollution is a recognized environmental hazard, the authors note that definitive evidence linking plastic particle exposure to specific health outcomes in humans is still limited and more realistic exposure studies are needed.
