Scientist outlines environmental fatality compared with tire uses for chemical 6PPD at Senate hearing

Washington State Department of Ecology Hazardous Waste and Toxics Reduction Program Manager Katrina Lassiter says in prepared testimony before the Senate Environment and Public Works Subcommittee on Chemical Safety, Waste Management, Environmental Justice, and Regulatory Oversight at a hearing about environmental impacts of 6PPD that scientists spent over 20 years investigating the mysterious deaths of coho salmon in Washington streams, eventually identifying 6PPD-quinone, a chemical derived from 6PPD used in tires, as the culprit in 2020, explaining that 6PPD transforms into 6PPD-quinone when it reacts with ozone and enters waterways through tire wear particles in air and stormwater runoff.
