A NEW WAY TO MAP PLASTICS IN TISSUE
Researchers at Kingston University, London have developed a method called photo acoustics, to locate and map microplastics in the tissue of mice. They inject plastics the size of a grain of salt into mice and use a laser beam to follow the plastic through tissue by the sound waves created as it bounces off the plastic. This method promises to be a great tool for use in humans. Finding microplastics in humans has usually been through autopsies, operations or biopsies. With this new method, doctors will be able to track microplastics over a longer timeframe without invasive procedures.
Lead researcher Dr. Stephen Patrick said, “Everyone on earth is exposed to microplastics today.” These tiny particles are in the air, food, water and soil. We are all vulnerable to them ending up in our bodies. We do not know for sure the damage they are causing to human health. (More next week on microplastics.)
