Humans inhale as much as 68,000 microplastic particles daily, study finds

Particles are small enough to burrow into lungs, says report, with health impacts 'more substantial than we realize'Every breath people take in their homes or car probably contains significant amounts of microplastics small enough to burrow deep into lungs, new peer-reviewed research finds, bringing into focus a little understood route of exposure and health threat.The study, published in the journal Plos One, estimates humans can inhale as much as 68,000 tiny plastic particles daily. Previous studies have identified larger pieces of airborne microplastics, but those are not as much of a health threat because they do not hang in the air as long, or move as deep into the pulmonary system.
