Microplastics found in fish from Yellowstone Lake

Yellowstone National Park may feel like a remote location, far from the problems of industrialized society. However, a recent study of Yellowstone Lake shows microplastics have infiltrated the aquatic food web, showing up in the stomachs of lake trout, cutthroat trout and tiny crustaceans on which both fish feed.

The research was prompted by another study examining lake trout diets, conducted by Stephanie Driscoll, of the Montana Cooperative Fishery Research Unit at Montana State University. When Driscoll told scientist Chris Guy she had found plastic in a lake trout’s stomach, he said it “was just like a gut punch.” Guy works for the research unit as a U.S. Geological Survey scientist.
