New Study Reveals Higher Daily Microplastic Inhalation Rates

New Study Reveals Higher Daily Microplastic Inhalation Rates
———————————
A new study led by researchers at the University of Toulouse suggests that adults may inhale significantly more microplastic particles daily than previously estimated, Anadolu Agency reported. Published in PLOS One, the research indicates that individuals breathe in approximately 68,000 plastic particles per day, a figure exceeding prior estimates by over 100 times.

The study focused specifically on smaller microplastic particles, ranging between 1 and 10 micrometers, which are more capable of penetrating deep into the lungs and potentially posing greater respiratory health risks. Using advanced Raman spectroscopy on air samples collected from both apartments and car cabins, researchers identified high concentrations of these minute plastic particles, with particularly elevated levels observed within vehicle environments.

Co-lead authors Nadiia Yakovenko and Jeroen Sonke warned that the inhalation of microplastics can lead to adverse health effects, including oxidative stress, immune dysfunction, and organ damage. They highlighted the increased risks associated with prolonged exposure in poorly ventilated car cabins during daily commutes. The study concludes with a call for more extensive research into the long-term health implications of microplastic inhalation and urges policymakers to address indoor air pollution.
