Skin, beauty and bath care products can contain the tiny bits of plastic that go down the drain and end up being flushed through the municipal sewage treatment system and into lakes and into the bellies of fish.

“It doesn’t go away,” said Parent. Toothpastes and deodorants are among the other common products that can contain microplastics, although some manufacturers are avoiding their use.

Once entering the Great Lakes waterway, the microplastics not only become a threat to aquatic life, but also endanger and become a contaminant for humans through the food chain.
