Every time a garment made from polyester or other synthetic fabric goes through the wash, it sheds tiny plastic fibers. Thousands of them. It turns out that these fibers end up fouling coastal environments throughout the globe, a global research team finds.
Itsy bitsy plastic pellets, such as those used for their abrasive qualities in products like skin cleansers and paint removers, also turn up in coastal sand, a separate study reports. Like polyester lint, these micropellets also go down the drain, through water treatment plants and into coastal waters.
