Microplastic and nanoplastic particles are now discoverable in human organs thanks to a new technique.
Microplastics have polluted the entire planet, from Arctic snow and Alpine soils to the deepest oceans. People are also known to consume them via food and water, and to breathe them in, but the potential impact on human health is not yet known.
The researchers expect to find the particles in human organs and have identified chemical traces of plastic in tissue. But isolating and characterising such minuscule fragments is difficult, and contamination from plastics in the air is also a challenge.
