Description This two-page focus sheet discusses Ecology’s ongoing work to reduce sources of 6PPD, with a particular focus on finding safer alternatives to 6PPD for use in tires. We describe: 1) the relationship between tires, 6PPD, 6PPD-q, and toxicity to aquatic organisms; 2) our approach to finding safer alternatives to 6PPD, including funding research and convening interested parties to promote innovation; and 3) the alternatives assessment we will conduct to identify and compare potential alternatives.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
