The Takeaway

We have known for years that microplastics are inside us, but we had no way to get them out. By using plasma exchange, researchers proved they can significantly drop the plastic concentration in a living person's bloodstream.

From the abstract

PurposeMicroplastic (1 µm to 5 mm) particles (MP) from of plastic waste in our environment may be inhaled, absorbed or ingested. They may enter the heart, lungs, GI tract and other systems and cause adverse effects including hemolysis, platelet aggregation, thrombosis or organ dysfunction. There is no established method for removing MP from the body. MP have been found in the eluate plasma from double filtration plasmapheresis, suggesting that circulating MP may be removed by apheresis.MethodsTh
