Tire Toxin Threatens Bay Area Fish
7 Jun
Summary
- A chemical in tires, 6PPD-Q, is highly toxic to fish.
- This chemical is linked to Coho Salmon die-offs.
- Researchers seek tire replacements to reduce pollution.
A chemical byproduct of car tires, known as 6PPD-Q, is emerging as a serious environmental concern for the Bay Area's aquatic life. This substance, present in nearly all tires, has been identified as highly toxic, with the potential to kill fish species.
Researchers first detected 6PPD-Q in local waterways about six years ago. The chemical is believed to be responsible for the significant die-offs and pre-spawn mortality events observed in Coho Salmon, a species particularly sensitive to its effects.
As tires wear down, they release 6PPD-Q, which accumulates in the environment, especially after storms. This poses a risk to species like Steelhead salmon that return to spawn during these periods.
Efforts are underway to regulate this chemical and find replacements that can extend tire life without posing a pollution risk. The state of California has begun implementing regulations, and the search for safer alternatives is ongoing.
