ClearImpact of Micro- and Nanoplastics on Mitochondria
This review examines how micro- and nanoplastics can damage mitochondria, the energy-producing structures inside cells that are critical for metabolism and cell survival. Researchers found that plastic particle exposure can trigger oxidative stress, disrupt mitochondrial membrane function, and interfere with energy production pathways. Since mitochondrial dysfunction is linked to numerous health conditions, the study suggests this may be a key mechanism through which plastic pollution affects human health.
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.

Mitochondria as a target of micro- and nanoplastic toxicity
This review examines how micro- and nanoplastics damage mitochondria, the energy-producing structures inside cells. Studies show that plastic particles can disrupt energy production, cause harmful oxidative stress, and interfere with the cell's ability to repair or recycle damaged mitochondria. Since mitochondrial damage is linked to many chronic diseases including heart disease, neurodegeneration, and diabetes, this helps explain why microplastic exposure may have widespread health effects.
The Mitochondrial Battleground: A Review of Microplastic-Induced Oxidative Stress and Inflammatory Pathways in Human Health
This review synthesizes research on how microplastics damage mitochondria through oxidative stress and inflammation across aquatic, terrestrial, and mammalian systems. Researchers found that microplastics generate reactive oxygen species that disrupt mitochondrial function, with smaller and aged particles causing greater toxicity, while inflammatory signaling creates a feedback loop that worsens cellular damage.
Microplastics/nanoplastics contribute to aging and age-related diseases: Mitochondrial dysfunction as a crucial role
This review examines how microplastics and nanoplastics may contribute to aging and age-related conditions by damaging mitochondria, the energy-producing structures inside cells. Researchers describe how these tiny plastic particles enter the body through food, water, and air, and accumulate in various organs where they can disrupt normal mitochondrial function. The study suggests that microplastic-driven mitochondrial damage could be an underappreciated factor in the aging process and related health decline.
Author comment: Mitochondria as a target of micro- and nanoplastic toxicity — R0/PR1
This review examines how microplastics and nanoplastics disrupt the function of mitochondria — the cell's energy-producing organelles — by triggering oxidative stress, altering membrane potential, and interfering with cell signaling. Because mitochondrial dysfunction is linked to neurodegenerative disease, cancer, diabetes, and cardiovascular conditions, this work raises concern that microplastic exposure could contribute to or worsen these diseases. The authors call for more targeted research into how plastic particles interact with cellular energy systems.

This review details how micro- and nanoplastics disrupt mitochondria — the energy-producing structures inside cells — by generating reactive oxygen species, altering membrane potential, and interfering with the quality-control processes cells use to maintain healthy mitochondria. Because mitochondrial dysfunction is a common driver of neurodegenerative diseases, cancer, diabetes, and cardiovascular disease, these findings suggest a plausible cellular mechanism linking plastic particle exposure to serious chronic illness. The review calls for more research into mitochondria as a key target of plastic toxicity.
