Great Lakes' latest pollution threat is 'microplastics'


August 12, 2019

Tiny plastic beads can slip past water treatment plants and into the Great Lakes.

A new contaminant has turned up in western Lake Superior - tiny snarls, tangles and shreds of plastic that are appearing by the hundreds of thousands, mystifying scientists and Minnesota pollution regulators.

While the level of debris doesn't approach the microplastic soup found near Hawaii, a gyre known as the Great Pacific Garbage Patch, it does exceed what's been found in the north Atlantic Ocean. The discovery has prompted researchers at the University of Minnesota, Duluth to expand testing to other Minnesota lakes and the fish that inhabit them.
