UM study finds microplastic pollution in Flathead Lake

They're in our oceans and rivers. They're in the food we eat and the water we drink. They've even been detected inside the human body. They're called microplastics—particles of plastic so small they can't be seen by the naked eye. While researchers have known for years that these microplastics exist in Flathead Lake, the concentrations and origins of the microplastic pollution have remained a mystery.
