"Unsettling Discovery: Laser Experiment Reveals New World in Ultrafine Membrane"

Researchers at Columbia and Rutgers have used new laser technology to detect nearly a quarter of a million nanoplastics per liter in bottled water, about 10 to 100 times more than previously estimated. Nanoplastics, smaller than one micrometer, can invade cells, damage DNA, and negatively affect human health and the environment. Individuals can reduce exposure by avoiding plastic water bottles and harmful plastic types, while researchers are working on biodegradable plastics and methods to prevent plastic particles from entering waterways.
