August 30, 2023 — Two fishing industry groups plan to sue a baker’s dozen of U.S. tire manufacturers over a chemical found in rubber tires, which the groups claim have had “devastating impacts” on salmon and steelhead.
The chemical, 6PPD, is used to prevent tires from degrading too quickly. However, it breaks down into 6PPD-quinone when exposed to ground-level ozone. The new chemical can kill coho salmon within hours of exposure and can lead to urban runoff mortality syndrome, according to environmental nonprofit Earthjustice, which is representing the Institute for Fisheries Resources (IFR) and the Pacific Coast Federation of Fishermen’s Associations (PCFFA) in the lawsuit.
