MINNEAPOLIS — Forty Minnesota lakes have worrisome levels of non-biodegradable microplastics, according to a University of Minesota study. Contaminants were found in every sampled lake, said environmental researcher Mary Kosuth. Of the sampled lakes:

> 100% contained fibers.

> 25% contained microplastic fragments.

> 12.5% contained film.

Kosuth called the contamination serious but correctable. She recommended:

> Repealing a state statute that forbids bans on plastic bags.

> Ending public policy that allows fossil fuels-to-plastic or plastics-to-fuel.

> Ending incentivizes to create new plastics.

> Preventing of clothing from going to landfills.

> Requiring filters on washing machines.

> Keeping waterways clear of microplastics.
