This can be a non-exhaustive checklist of locations microplastics have been discovered: Mount Everest, the Mariana Trench, Antarctic snow, clouds, plankton, turtles, whales, cattle, birds, faucet water, beer, salt, human placentas, semen, breast milk, feces, testicles, livers, brains, arteries, and blood.
My blood, particularly. In early March I milked a couple of drops out of my fingertips and despatched the pattern to be examined for microplastics.

Every week round 10 to fifteen individuals stroll into the basement clinic simply off Harley Avenue—a highway famed for its non-public clinics and rich clientele. After a session, the sufferers quiet down in an armchair for the therapy. Blood is drawn from a cannula right into a machine that separates out the plasma from blood cells. That plasma is filtered by way of a column that’s purported to entice microplastics and different undesirable chemical compounds, earlier than being combined again with the blood cells and pumped again into the affected person. All-in-all the method runs for as much as two hours—sufficient time to course of 50 to 80 p.c of the blood plasma quantity.

There have been an onslaught of scientific papers which have tracked microplastics to each inch of the Earth’s floor and deep inside our our bodies, however only a few try and tease out the impression these have on our well being.
