Study: Microplastics in majority of Oregon shellfish

PORTLAND, Ore. (AP) — A Portland State University study found tiny pieces of plastic in the vast majority of razor clams and oysters sampled along the Oregon coast.

The Oregonian/OregonLive reported Tuesday that up to 700,000 of the microscopic fibers are shed by yoga pants, fleeces and other active outerwear made of synthetic textiles during a wash.

These fibers are in the wastewater from laundry machines that eventually winds up in the ocean.

Some of the tiny plastic fibers could also come from derelict fishing gear.

The study’s authors collected and sampled shellfish from 15 sites from Clatsop in the north to Gold Beach near the California border.

Of the roughly 300 shellfish studied, all but two contained at least some microplastics.

There was an average of 11 pieces of microplastic in each specimen.
