Researchers Finding Plastics' Great Lakes Pollution
They’re finding tiny, perfectly round beads of plastic in many of the samples, and this might hold another clue about the source of particles. “The cosmetics industry uses plastic micro-beads in soaps, toothpaste and other products. Because the products are not designed for ingestion, they don’t have to test for this. It’s completely unregulated and may be a significant source of micro-plastics finding their way into the environment,” she says....
More research is needed to compare the amount of plastic pollution from one lake to the next...The team plans to sample the St. Lawrence River and Lakes Erie, Michigan, and Ontario this summer, and as funding allows, to carry out more systematic studies of all five lakes.
