Tiny polymer particles infiltrate the human body to an unforeseen extent

Researchers in the UK have discovered microplastics in live lung tissue for the first time, which adds to growing evidence that humans breathe these extremely small particles. The study was published last month in Science of the Total Environment.
Microplastics are trace particles measured at under 0.2 millimeters in diameter and often invisible to the naked eye.
Earlier studies had already discovered microplastic particles in all parts of the body, including the lungs. But that research was accomplished using tissue gathered from cadavers. This time, scientists were able to observe the widespread pollutant in live tissue gathered from live patients in the course of routine surgery.
