Nanoplastics and Human Health: Hazard Identification and Biointerface
AI summary Read the abstract
This review covers what we know about nanoplastics and their potential effects on human health, including how they enter the body and what happens when they get inside cells. Nanoplastics can penetrate cell membranes and damage internal structures like mitochondria, which are responsible for producing energy in cells. The review also discusses strategies to reduce nanoplastic levels in the environment to protect human health.
Nanoplastics are associated with several risks to the ecology and toxicity to humans. Nanoplastics are synthetic polymers with dimensions ranging from 1 nm to 1 μm. They are directly released to the environment or secondarily derived from plastic disintegration in the environment. Nanoplastics are widely detected in environmental samples and the food chain; therefore, their potentially toxic effects have been widely explored. In the present review, an overview of another two potential sources of nanoplastics, exposure routes to illustrate hazard identification of nanoplastics, cell internalization, and effects on intracellular target organelles are presented. In addition, challenges on the study of nanoplastics and future research areas are summarized. This paper also summarizes some approaches to eliminate or minimize the levels of nanoplastics to ensure environmental safety and improve human health.

Micro/nanoplastics and human health: A review of the evidence, consequences, and toxicity assessment
AI summary Read the abstract
This review summarizes evidence that micro and nanoplastics have been found in multiple human organs and body fluids, where they can alter cell shape, damage mitochondria, reduce cell survival, and cause oxidative stress. The health effects depend heavily on the size, shape, and chemical makeup of the particles, with smaller nanoplastics generally posing the greatest risk because they penetrate deeper into tissues. The review provides a framework for assessing how dangerous different types of plastic particles are to 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 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.
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.
Impact of microplastics and nanoplastics on human Health: Emerging evidence and future directions
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.
