EcoCity Action on Mythryl: “By bussing instead of driving, ~30 people prevented ~25g of tire…”

By bussing instead of driving, ~30 people prevented ~25g of tire particulates from running into our waterways. That much tire dust would’ve leached 130ug of 6-PPDQ, extremely toxic to salmon [1]. This much 6-PPDQ would contaminate 700 gallons of water to a degree that’s lethal to coho salmon [2].

On the buses to Fishaqua (Issaquah) for Salmon Days! If all 30+ people on the bus+shuttle drove their own cars instead, it would shed 25000mg extra of tire particulates into the watershed
