"Microplastic fibers were found deep in the lower lungs of living human beings in almost every person sampled in a recent UK study.
The study from Great Britain discovered microplastic particles — present in many COVID-19 masks — in the lung tissue of 11 out of 13 patients undergoing surgery.
Polypropylene (PP) and polyethylene terephthalate (PET) were the most prevalent substances present in the lungs.
The microscopic plastic fragments and fibers were discovered by scientists at Hull York Medical School in the UK. Some of the filaments were two millimeters long in patients undergoing surgery whose lung tissue they sampled.
The plastic dust and microscopic debris comprise the same plastics used to manufacture the ubiquitous surgical masks worn by hundreds of millions of people around the world as mandated by governments in an attempt to halt the spread of COVID-19."
