A groundbreaking University of British Columbia study warns that artificial turf poses a lethal threat to coho salmon populations.
The fields utilize crumb rubber derived from recycled tires. Research indicates these surfaces leach 6PPD-quinone into stormwater runoff. This chemical compound is known to cause rapid mortality in coho fish.
Katie Moloney, a PhD candidate leading the investigation, notes that contamination levels remain consistent regardless of field age. She estimates an average field contains 125 metric tonnes of rubber material equivalent to 20,000 passenger vehicles.
Initial alarms rose after North Vancouver Streamkeepers observed mass die-offs adjacent to treated fields. Scientists suggest installing planted soil filters to mitigate runoff toxicity. Without intervention, the hazard persists throughout the infrastructure lifespan.
