KEY LARGO, Fla. (AP) — Comfortable clothes are emerging as a source of plastic that's increasingly ending up in the oceans and potentially contaminating seafood, according to Gulf Coast researchers launching a two-year study of microscopic plastics in the waters from south Texas to the Florida Keys.
The project , led by the Mississippi-Alabama Sea Grant Consortium, will rely partly on volunteers in coastal cleanup events. It also will expand a year's worth of data collected around Florida that predominantly found microfibers — shreds of plastic even smaller than microbeads flowing down bathroom sinks and shower drains.
Yoga pants, fleece jackets, sweat-wicking athletic wear and other garments made from synthetic materials shed microscopic plastic fibers — called "microfibers" — when laundered. Wastewater systems flush the microfibers into natural waterways, eventually reaching the sea.

"Anything that's nylon or polyester, like the fleece-type jackets," University of Florida researcher Maia McGuire said.
When McGuire set out to study the kinds of plastic found in Florida waters, she expected to mostly find microbeads — the brightly-colored plastic spheres the U.S. government banned from rinse-off cosmetic products in 2015 because of the potential threat to fish and other wildlife.
Instead, McGuire predominantly found microfibers, even smaller than microbeads and coming from places most people don't consider dangerous to marine life: their closets.
"I totally thought we were going to be finding microbeads and (bigger) fragments," McGuire said. "What do we do about it is the multimillion dollar question. The consensus seems to be that we need improvement in technology in washing machines and wastewater treatment plants in combination in order to try and filter out these fibers. There's just so much we don't know."
