PLASTIC IN THE OCEAN: BILLIONS OF MICROPLASTIC NANOPARTICLES FOUND IN SCALLOP INTESTINES IN JUST HOURS
Billions of nanoplastics can collect in shellfish in just a few hours, scientists have found.
Scientists at the University of Plymouth in the U.K. exposed scallops to the nanoplastic carbon-radiolabeled nanopolystyrene in a laboratory setting. After six hours, they found billions of tiny particles had built up throughout their bodies.
The researchers found particles measuring 20 nanometers (0.00002 millimeters) in muscles, gills, kidneys and other organs and measuring 250 nanometers (0.00025 millimeters) in their intestines.
However, after 14 days, equipment could no longer pick up the 20-nanometer size particles in the creatures, and 48 days for the 250 nanometers pieces.
