What happened

New research indicates that when water contacts plastic surfaces, a key chemical reaction takes place, producing free radicals. Lab experiments suggest tiny bits of plastic can react with water inside the body to create highly reactive molecules. These molecules can lead to oxidative stress and inflammation.

Why it matters

The effect on people remains an ongoing question.
