Sean Dixon — Puget Soundkeeper The tires of your car have a chemical in them, called 6PPD, that slows tire degradation by binding with oxygen and ozone that could break down the rubber. But these same reactions that protect the rubber are also creating a new chemical, called 6PPD-quinone, which scientists just found in 2020 to be highly toxic to aquatic organisms. 6PPD is in essentially every tire made since the 1960s, and aquatic ecosystems around the world, particularly in dense urban areas, are in danger. Coho salmon is particularly susceptible to the toxin, and salmon populations in the Seattle area have been decimated by stormwater runoff containing the tiny particles that wear off tires as they speed down the road. Now that the science is clear, the search is on to find a substitute for 6PPD; but for many years to come, the pollutants will continue to shed from our tires and into our waterways. How to stop the stormwater from getting to the salmon and other aquatic organisms is one of the many ways that the Puget Soundkeeper Alliance is advocating for the ecological health of Puget Sound and other waterways in the Seattle area. Sean Dixon leads these efforts as the executive director of the Puget Soundkeeper Alliance, which is part of the worldwide network of waterkeepers. I discuss with Sean the work he’s doing in Seattle but also the waterkeeper movement more broadly and the importance of organized, community-engaged action to protect waterways and the diverse ecosystems that depend on them across the planet.
