Scientists Warn Microplastic Pollution Has Gone Airborne, Threatening Human Health

Aug 15, 2019

Writing in the journal Science Advances, researchers called for more studies on the effects of plastic pollution on human health. They cited a 1998 study that found inhaled microplastics may contribute to the risk of lung cancer.
