'Alarmingly high' amounts of plastic microbeads found in B.C. shellfish farming areas
Areas off the B.C. coast used for farming shellfish are becoming highly polluted by plastic microbeads, new research has found. According to a release from Simon Fraser University, researchers analyzed dozens of sediment samples from 16 sites around Lambert Channel and Baynes Sound off Denman Island — where 130 shellfish farms are located — and found "alarmingly high" amounts of plastic pollution. "We found microbeads in the smallest bits of sediment and in a concentration equal to the amounts of silt and organic matter," Leah Bendell, professor of marine ecology and ecotoxicology at SFU, said in the statement. Plastic pollution, Bendell told All Points West host Jason D'Souza, is a long-term problem.  Results from beach cleanups have found about 90 per cent of that plastic actually comes from the shellfish industry itself. She says what still remains unknown is how the plastic, when eaten by shellfish, affect both them and the animals that feed on them. For instance, are the plastics contaminated with heavy metals?
