UBC Study: Turf Fields Kill Salmon

A study by the University of British Columbia found that artificial turf fields in Canada — Vancouver Island leach 6PPD, a chemical lethal to Coho salmon, into stormwater systems. This chemical originates from crumb rubber infill made from recycled tires, and its release persists throughout the fields' lifespan. The research, supervised by Rachel Hawkins and involving Katie Moloney, detected 6PPD concentrations exceeding lethal levels for juvenile Coho salmon, along with heavy metals like zinc and copper. The findings suggest a need for stormwater treatment or alternative infill materials, though non-rubber options are more expensive. The European Union has already banned crumb rubber, and Canada's federal government has designated 6PPD for priority assessment, indicating growing regulatory attention to tire-derived pollution.
