Waters off B.C. coast awash in plastic particles. Vancouver Sun


If it’s there, it’s here. Could this issue have links to other problems we are seeing in the marine environment? Very likely. This could be a great project for some researchers here as well. The PT Marine Science Center did surveys of the beaches a few years ago and also found extensive plastic pollution almost everywhere they looked.

Water samples from off the B.C. coast have found up to about 9,200 particles of plastic per cubic metre, the director of a new ocean pollution program at the Vancouver Aquarium said Tuesday. Based on 34 water samples taken between inshore waters and 1,200 kilometres due west of Victoria, the concentrations of microplastics — pieces typically the size of a coffee ground — were found to increase in proximity to the mainland coast. Microplastics can be ingested by plankton, invertebrates and other marine life forming the base of the food chain; ingestion of plastics may make organisms think they are full, causing them to starve. “There is extensive contamination of sea water by microplastics,” confirmed Peter Ross, a former research scientist with the federal Institute of Ocean Sciences in Sidney on Vancouver Island. “It raises the questions: where are they coming from and do they pose a threat to the food web? This will remain a priority for the aquarium.” Larry Pynn reports.
