News release: California to tire makers – Please remove harmful chemicals that threaten our aquatic life and waterways
The California Department of Toxic Substances Control (DTSC) put tire manufacturers on notice that California wants them to explore alternatives to using zinc, a toxic chemical that harms aquatic life and burdens waterways. Zinc helps make rubber stronger, but also wears off tire tread and washes into storm drains, streams, rivers and lakes, threatening California fish and other aquatic organisms.
