70,000 Pieces of Plastic Shed Daily from Objects in Our Homes and Cars and Penetrate ‘Deep Inside Our Lungs’

Humans are inhaling around 70,000 pieces of plastic daily, with a significant portion originating from within their homes and cars, a recent study reveals. The microscopic plastic particles are capable of entering deep into our respiratory system, posing potential risks of inflammation or irritation, according to researchers. The concentration of microplastics and nanoplastics within indoor living spaces is higher than previously believed, as per a study published in the journal Plos.

The study found that microplastics, which are comparable in size to a grain of sand, as well as nanoplastics, which are thousands of times smaller, can be found in various household objects such as carpets, tile floors, curtains, and even within the interior of cars. These particles, when inhaled, have the ability to penetrate deep into the lungs. The research team consisting of Nadiia Yakovenko and Jeroen E. Sonke from the Université de Toulouse in France highlighted that the number of plastic particles discovered was 100 times greater than previous estimates.

Cars are identified as a significant concern as they are confined spaces filled with plastic-based materials like dashboards, seat fabrics, and carpets that can shed tiny plastic particles. The researchers noted that due to limited ventilation in car cabins, microplastic particles have the potential to accumulate, increasing the likelihood of inhalation during regular commutes or extended drives. The ingestion of these plastics can lead to respiratory issues, as toxic additives like bisphenol A and phthalates may enter the bloodstream.

The long-term exposure to microplastics and their additives raises concerns about potential adverse health effects, including respiratory problems, disruption of endocrine function, increased risk for neurodevelopmental disorders, reproductive birth defects, infertility, cardiovascular disease, and cancers. The researchers emphasised that while further research is ongoing, the impact of prolonged exposure to these particles cannot be understated.

Moreover, microplastics have been identified in various human organs such as the brain, testicles, and placenta, with experts cautioning about their widespread presence globally. The omnipresence of these particles has led to them being described as a “time bomb” by some experts due to the associated health risks they pose. The discovery of such particles in critical organs underscores the urgency of addressing the issue of plastic pollution and its impact on human health.

Efforts to reduce plastic pollution and limit human exposure to microplastics are essential in safeguarding public health. Individuals and policymakers alike are encouraged to adopt eco-friendly practices and policies that minimise the use of plastics, particularly in indoor environments where exposure levels appear to be alarming. By raising awareness and taking proactive measures, we can work towards mitigating the health risks associated with plastic pollution.

In conclusion, the findings of the study shed light on the pervasive nature of microplastic pollution and its detrimental effects on human health. It underscores the importance of proactive measures to address plastic contamination in indoor spaces and reduce the risks posed by inhaling plastic particles. As research in this field continues to evolve, prioritising sustainable practices and policies is crucial in safeguarding our respiratory health and well-being in the face of plastic pollution.
