ClearRecent insights into uptake, toxicity, and molecular targets of microplastics and nanoplastics relevant to human health impacts
This review summarizes what scientists know about how tiny plastic particles enter the human body and cause harm at the cellular level, including through inflammation, oxidative stress, and disruption of important cell signaling pathways. Americans are estimated to consume tens of thousands to millions of micro- and nanoplastic particles per year, and these particles can penetrate cells and tissues throughout the body.

Cellular and Molecular Mechanisms of Micro- and Nanoplastics Driving Adverse Human Health Effects
This review examines the biological mechanisms by which micro- and nanoplastics may cause harm in humans, including oxidative stress, inflammation, disruption of protective barriers, and immune system problems. Evidence from lab and animal studies suggests these particles can affect the gut, heart, brain, and reproductive systems, though human data is still limited to detecting plastics in tissues rather than proving they cause specific diseases. The authors highlight that most studies use higher doses than people actually encounter, making it important to develop research models that better reflect real-world chronic exposure.
Plastic pollution and its pathophysiological impacts on mammalian cells
This review examines the pathophysiological impacts of microplastics and nanoplastics on mammalian cells, discussing how environmental degradation of larger plastics generates micro- and nano-scale fragments that enter organisms through ingestion, accumulate via trophic transfer, and cause cellular toxicity. The authors synthesize laboratory evidence on MP and NP interactions with mammalian cells including membrane disruption, inflammation, and genotoxicity.

Micro- and nano-plastics activation of oxidative and inflammatory adverse outcome pathways
This review maps the biological harm caused by micro- and nanoplastics to formal toxicity pathways, finding that oxidative stress is a common starting point for damage at every level from cells to whole organisms. Researchers found that in ecological settings, this oxidative damage cascades into growth inhibition and behavioral changes, while in human health contexts it may trigger inflammatory responses. The study highlights that more mammalian research is needed to fully define the health risks of plastic particle exposure.

Polytetrafluorethylene microplastic particles mediated oxidative stress, inflammation, and intracellular signaling pathway alteration in human derived cell lines
Scientists tested PTFE (Teflon) microplastics on six types of human cells and found they caused oxidative stress, inflammation, and disrupted cell signaling pathways in most cell types. Smaller PTFE particles generally caused more damage than larger ones, and lung and intestinal cells were particularly affected. Since PTFE is widely used in nonstick cookware and other household products, these findings raise questions about health risks from Teflon-derived microplastic exposure.
Microplastics and Nanoplastics in Human Health: Toxicological Mechanisms Involving Oxidative Stress, Endocrine Interference, and Inflammatory Responses
This review of existing research shows that tiny plastic particles from broken-down plastic waste can harm our bodies in three main ways: by damaging cells, disrupting hormones, and causing inflammation. These microscopic plastics are now everywhere in our environment - in the air we breathe, water we drink, and food we eat - and studies suggest they may contribute to health problems affecting our hearts, digestive system, and other organs. While scientists are still studying exactly how dangerous these particles are to humans, the evidence suggests we should be concerned about our constant exposure to plastic pollution.
