Invisible Tire Tracks: Understanding Tire Wear Particles & 6PPD-q

Every time we drive, our tires wear down, releasing particles and a toxic chemical byproduct known as 6PPD-q into our environment. What does this mean for our local ecosystems and waterways? Eli Mackiewicz, with the City of Bellingham's Natural Resources Program and Shelby Giltner, with the Department of Ecology break down the science behind 6PPD and 6PPD-q, explore how we are addressing the issue, and share practical ways you can get involved and take action in this engaging lecture and community discussion. Presented on October 21, 2026 as part of the Whatcom Watersheds Information Network's Speaker Series. To learn more about WWIN, visit WhatcomWin.org.
