Recent research on Great Lakes contaminants has shown that microplastics – small beads of plastic used in many exfoliants, toothpastes, and other products – are contributing to pollution levels. As a result, mayors near the Great Lakes are calling on manufacturers to remove the plastics from their products. 

From TheObserver.ca

“The Great Lakes and St. Lawrence Cities Initiative, representing more than 100 Canadian and U.S. cities, is urging industry and governments to have microplastics removed from personal care products.

Its call came as a study on microplastic pollution was published based on sampling last summer on Lake Huron, Erie and Superior led by Sherri Mason, a professor at the State University of New York at Fredonia.

‘It takes that kind of initiative to get things to change,’ she said of the mayor’s support for the issue.
‘It’s not so much about cleaning it up, as it is about stopping it at its source.’

Mason returned to the lakes for seven weeks this summer to collect more samples, including one from the St. Clair River at Sarnia that will be analyzed as the study continues.

Samples taken in 2012 included green, blue and purple coloured spheres, similar to polypropylene and polyethylene microbeads in consumer products, such as facial cleaners.”
