Microplastics/nanoplastics contribute to aging and age-related diseases: Mitochondrial dysfunction as a crucial role
AI summary Read the abstract
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.
The pervasive utilization of plastic products has led to a significant escalation in plastic waste accumulation. Concurrently, the implications of emerging pollutants such as microplastics (MPs) and nanoplastics (NPs) on human health are increasingly being acknowledged. Recent research has demonstrated that MPs/NPs may contribute to the onset of human aging and age-related diseases. Additionally, MPs/NPs have the potential to induce mitochondrial damage, resulting in mitochondrial dysfunction. Mitochondrial dysfunction is widely recognized as a hallmark of aging; thus, it is necessary to elucidate the relationship between them. In this article, we first elucidate the distribution of MPs/NPs in various environmental media, their pathways into the human body, and their subsequent distribution within human tissues and organs. Subsequently, we examine the interplay between MPs/NPs, mitochondrial dysfunction, and the aging process. We aspire that this article will enhance awareness regarding the toxicity of MPs/NPs while also offering a theoretical framework to support the development of improved regulatory policies in the future.

Impact of Micro- and Nanoplastics on Mitochondria
AI summary Read the abstract
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
AI summary Read the abstract
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.

This review examines how micro- and nanoplastics damage mitochondria, the energy-producing structures inside our cells. Research shows these tiny plastic particles can cross biological barriers, enter cells, and disrupt mitochondrial function by triggering oxidative stress and altering energy production. Since mitochondrial damage is linked to diseases like cancer, diabetes, and neurodegeneration, this represents a key concern for human health.
Mitochondria as a target of micro- and nanoplastic toxicity
AI summary Read the abstract
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.
Micro- and Nanoplastics as Potential Chronic Abiotic Stressors: Cellular Senescence, Hallmarks of Ageing, and an Oxidative–Mitochondrial–Inflammatory Framework
AI summary Read the abstract
This review summarizes existing lab research on tiny plastic particles and cell ageing processes. Studies found effects on cell energy production, DNA, and inflammation signals, with strongest evidence for mitochondrial problems and cell senescence, but most used high doses and short exposures, so links to human ageing remain unconfirmed.
