Plastic microbeads from face wash are showing up all over

Tiny balls of plastic from cosmetic products are showing up in river sediment for the first time, mixing with the rocks and dirt that line the bed of the Saint Lawrence River. Because scientists have mostly been looking for these plastic pollutants in the surface water instead of in the dirt, it means that their build-up could be even worse than previously imagined -- and fish and other animals could be in serious trouble because of them.
