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. 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. The smaller bits measure between 1 and 10 micrometers, or about one-seventh the thickness of a human hair, and present more of a health threat because they can more easily be distributed throughout the body.
