All organisms harbor an invisible, omnipresent enemy: plastic. Researchers worldwide have shown that plastic particles can also be detected in humans – in organs and bodily fluids.Researchers in Barcelona, Vienna, Bologna, Grenoble and Catania have detected microplastics in human organs and bodily fluids: in lungs, intestines, heart, blood and semen, in placenta and in breast milk. Detecting plastic in human tissue is a mammoth task, both technically and scientifically. Plastic particles can range from a few millimeters to a single nanometer and are difficult to detect, let alone capture.
