[Clinical impact of microplastic exposure in humans].
Summary
This review summarized clinical evidence on the health impacts of microplastic exposure in humans, covering routes of entry (air, food, contact) and the range of organ systems affected. It concluded that while data are still emerging, current evidence supports concern about microplastic accumulation and its potential to cause inflammation, oxidative stress, and systemic health effects.
There are increasing concerns about the impact of synthetic (plastic) materials on the environment and their potential health risks to humans. The use of plastics in food packaging, clothing, medical products, and car tires can release small plastic particles that enter the human body through air, food, or direct contact. The World Health Organization has evaluated the health risks associated with these so-called microplastics. However, measuring microplastics in the environment and the human body, as well as toxicological research in animal models and cell cultures, remain challenging. Improved methodologies are needed to enhance the quality and specificity of outcomes. Significant knowledge gaps persist, including the role of microplastics in (infectious) diseases. Recent clinical studies have detected microplastics in human tissues such as blood vessels, kidneys, livers, and brains, and have investigated a relationship with diseases like atherosclerosis and dementia. The Netherlands is highly active in microplastics research and is developing a knowledge agenda to mitigate the health risks of microplastics.

[Human Accumulation and Toxic Effects of Microplastics：A Critical Review].
This review summarizes how microplastics enter the human body through food, drinking water, and air, and where they tend to accumulate in organs and tissues. Researchers found evidence that microplastics can trigger inflammatory responses and oxidative stress in the body. The study calls for more research into the long-term health effects of continuous microplastic exposure in humans.
The Impact of Microplastic on Human Health
This review synthesized evidence on microplastic exposure pathways and health effects in humans, finding that microplastics enter the body via ingestion, inhalation, and dermal contact and are associated with oxidative stress, inflammation, genotoxicity, and endocrine disruption.
Microplastics and Human Health: A Comprehensive Review on Exposure Pathways, Toxicity, and Emerging Risks
This comprehensive review examines microplastic exposure pathways in humans, methods of detection, and the potential toxic effects on various biological systems. The study highlights growing evidence that microplastics can enter the body through ingestion, inhalation, and dermal contact, and may affect multiple organ systems, though significant uncertainties remain about long-term health outcomes.
The potential effects of microplastics on human health: What is known and what is unknown
This review summarizes what is currently known about how microplastics might affect human health, noting that while contamination is widespread in food, water, and air, direct evidence of harm in humans is still limited. Studies in animals and cell cultures suggest microplastics could trigger immune responses, cause inflammation, and affect reproduction and development. The authors call for more rigorous clinical studies to determine whether the levels of microplastics that people actually encounter pose real health risks.
