The findings raise concerns about long-term human health effects from chronic exposure to these nearly invisible plastic particles.
Environmental nanoplastics induce mitochondrial dysfunction: A review of cellular mechanisms and associated diseases
This review summarizes how nanoplastics, which are small enough to enter individual cells, damage mitochondria (the energy-producing structures inside cells) by disrupting their shape, function, and ability to produce energy. This mitochondrial damage has been linked to a range of diseases including neurodegeneration, diabetes, cardiovascular disease, and reproductive problems. The findings help explain why nanoplastic exposure may contribute to multiple chronic health conditions through a common cellular mechanism.

Probing Long-Term Impacts: Low-Dose Polystyrene Nanoplastics Exacerbate Mitochondrial Health and Evoke Secondary Glycolysis via Repeated and Single Dosing
This study exposed human intestinal cells to low doses of polystyrene nanoplastics over 12 days and found that repeated exposure caused cumulative damage to mitochondria, the energy-producing structures inside cells. Even concentrations considered environmentally realistic impaired cellular energy production and forced cells to switch to a less efficient backup energy system. This suggests that long-term, everyday nanoplastic exposure through food could gradually harm gut health in ways that might not be immediately noticeable.
Polystyrene nanoplastics trigger mitochondrial and metabolic reprogramming in cardiomyocytes: Evidence from integrated transcriptomic and metabolomic analysis
Scientists found that tiny plastic particles called nanoplastics can damage heart cells by disrupting their powerhouses (mitochondria) and reducing their ability to produce energy. When researchers exposed human heart cells and mice to these nanoplastics, they observed weakened heart function and signs of early heart damage. This research suggests that the growing amount of microscopic plastic pollution in our environment could pose previously unknown risks to heart health.

Nanoplastics exposure-induced mitochondrial dysfunction contributes to disrupted stem cell differentiation in human cerebral organoids
Using lab-grown human brain organoids (miniature brain models), researchers found that polystyrene nanoplastics damaged mitochondria (the energy-producing structures in cells), leading to increased cell death and disrupted development of brain stem cells. These findings suggest that nanoplastic exposure could interfere with how brain cells develop and function, raising concerns about the neurological effects of environmental plastic pollution on humans.
Hazard assessment of different-sized polystyrene nanoplastics in hematopoietic human cell lines
Researchers tested how different sizes of polystyrene nanoplastics (50, 200, and 500 nm) affect human blood cell lines. While none of the sizes caused direct cell death, all three were taken up by cells and disrupted mitochondrial function in immune-related cell types. The study suggests that even without killing cells outright, nanoplastics may interfere with important cellular energy processes, with effects varying by particle size and cell type.
Cellular and bioenergetic effects of polystyrene microplastic in function of cell type, differentiation status and post-exposure time
Researchers tested polystyrene microplastics on human lung, colon, and liver cells and found that even a single exposure had lasting effects on cell energy production and caused oxidative stress that continued for 12 days after exposure ended. Colon cells were particularly affected, showing signs of mitochondrial dysfunction long after the initial contact with microplastics. These findings suggest that microplastic exposure through food could cause sustained damage to intestinal cells even after the particles have passed through the body.
