UBC study links artificial turf fields to lethal chemical threat for salmon
A new study from the University of British Columbia has found that artificial turf fields across Metro Vancouver leach 6PPD-quinone, a chemical known to kill coho salmon, into municipal stormwater systems—and the contamination persists long after the fields are installed.
Researchers traced the pollution to crumb rubber infill made from recycled tires, a material widely used on synthetic turf fields. The team found it consistently released 6PPD-quinone and other contaminants across fields of different ages.
“An average turf field contains about 125 tonnes of crumb rubber, roughly 20,000 tires,” said Katie Moloney, a PhD student ...
