Microplastics Detected in the Environments of Our Homes and Cars

• Research revealed 68,000 microplastic particles in the environment daily.
• Microplastics can negatively affect health, including causing respiratory issues.
• In cars, the concentration of microplastics is higher than in homes.

Research published on July 30, 2025, in the journal PLOS One found that the environment in our homes and cars can contain thousands of microplastic particles, which may pose health risks. Researchers from the University of Toulouse in France, led by Nidiya Yakovenko, conducted an analysis of the environment in apartments and cars, finding that indoors, there can be nearly 68,000 microplastic particles ranging in size from 1 to 10 micrometers daily. This is 100 times more than previously expected.

The study indicated that microplastics are a result of the degradation of plastic objects, such as carpets, curtains, and interior car components. Microplastic particles smaller than 10 micrometers can penetrate deeply into the lungs, which can lead to health issues. Long-term exposure can cause problems with breathing, disrupt endocrine function, and increase the risk of developing various health issues, such as cancer.

Researchers noted that the concentration of microplastics in enclosed spaces is significantly higher than in open air. They found that in cars, the amount of microplastic particles per cubic meter of air reaches 2,238, which is significantly more than the 528 particles in similar environments at home. This indicates that cars can be a major source of microplastic pollution, especially in enclosed spaces with limited ventilation.

Researchers emphasize the need for further studies on the impact of microplastics on human health, as their effects may be much more serious than previously thought. This research highlights the importance of understanding the problems associated with microplastic pollution in everyday life.
