McGill professor Anthony Ricciardi and his students search the St. Lawrence River to find and study the invasive species that live below the river’s surface.
On one particular day, they were looking for Asian clams in the sediment of the river, but upon closer inspection they found another invader.
“There were little round spheres that were clearly unnatural and synthetic and we had a suspicion given what we've heard about plastic pollution that these may be plastic microbeads,” Ricciardi explained.
