Plastic pollution is becoming a growing problem in the Great Lakes, especially near busy cities and industries
As the people of Toronto flocked to the Lake Ontario waterfront to swim, paddle and generally escape pandemic isolation, Chelsea Rochman’s students at the University of Toronto were throwing plastic bottles with GPS trackers into the water.
The research team‘s goal is to track trash that ends up in the lake, to figure out where it accumulates in the water and where it’s coming from in the first place.
Using information from the tracking bottles, they chose spots to put in Seabins — stationary cleaning machines that suck in water all day and trap any garbage and debris — at marinas along the waterfront. They are emptied daily, and the debris collected in them is examined to ferret out what kinds of trash is getting into the lake.
