Microplastics, these particles invisible to the naked eye, have become a major concern for public health. A recent study reveals that the air of our homes and cars could contain up to 68,000 particles of microplastics per day. These particles, small enough to deeply penetrate into the lungs, have potential health risks. This phenomenon, long neglected, raises essential questions about indoor air quality and the impacts of omnipresent synthetic materials in our daily environment.
An invisible daily threat
Unlike previous research focused on plastic pollution in the oceans, this study focuses on a much more intimate framework: our interior living spaces. Researchers have discovered that microplastics are omnipresent in houses and cars. These particles come from the degradation of many plastic objects present in our daily environment, such as carpets, curtains and textiles. These discoveries highlight the importance of considering indoor air as a significant source of pollution.
The study results show that more than 90 % of the detected particles measure less than 10 micrometers. This means that they are smaller than a grain of dust and can penetrate deep into the lungs during inhalation. The capacity of these particles to reach the respiratory system is worrying because they could potentially enter the blood circulation.

Cars, risky spaces
The interiors of cars prove to be particularly worrying exhibition areas. Cars’ interns, often closed and filled with plastic -based materials, are important sources of microplastics. The dashboards, the tissues of the seats and the carpets can release tiny plastic particles over time, especially under the effect of heat, friction and daily use.
The researchers point out that, since we spend a large part of our time in these confined spaces, exposure to microplastics is inevitable. This situation calls for a reflection on the materials used in the manufacture of cars and on the measures to be taken to reduce their degradation.

Worrying health implications
The consequences for human health are worrying. The inhalation of microplastics can cause inflammation or irritation of the respiratory tract. These particles also transport toxic additives, such as bisphenol A and phthalates, which can reach blood circulation. Researchers are concerned about the long -term effects of this exposure, which could contribute to respiratory problems, disrupt endocrine function or increase the risk of cardiovascular disease and cancer.
The results of this study, published in the newspaper PLOS Oneunderline the urgency of reconsidering the quality of the indoor air. The researchers hope that their conclusions will encourage a revision of air quality standards and public health recommendations.
Towards a necessary awareness
The conclusions of this research call for an increased awareness of pollution by microplastics in interior spaces. While the external air quality is often at the center of concerns, this study highlights the importance of looking at the air that we breathe inside our homes and cars. Microscopic microplastics could have devastating effects on our long -term health.
The researchers hope that these discoveries will encourage changes in the design of the materials used in everyday consumer products. The question arises: how will this information influence future recommendations for public health and internal air quality standards?
Faced with this invisible but omnipresent threat, it is crucial to reconsider our immediate environment. Microplastics, present in the air that we breathe daily, could have unsuspected consequences on our health. What changes will be necessary to protect our well-being in the face of this interior pollution?
