For decades, toxic tire dust has choked coho salmon before they can spawn in their natal streams. Now, King County scientists say they have made a “potential breakthrough” in how to save them.

A bipartisan group of Washington legislators has filed a bill in Olympia asking Congress and the Trump Administration to modify the Marine Mammal Protection Act to allow lethal removals of sea lions and harbor seals and other actions in more of the state to save ESA-listed Chinook and other salmon populations.

In early 2000, scientists at 3M, the chemicals giant, made a startling discovery: High levels of PFAS, the virtually indestructible “forever chemicals” used in nonstick pans, stain-resistant carpets and many other products were turning up in the nation’s sewage.
For decades, Coho salmon were turning up dead in urban streams the Pacific Northwest. The salmon would stop swimming straight, and then die before they had a chance to spawn. Researchers worried that unless they figured out the cause, the species would eventually go extinct.
In May 2024, our Safer Products for Washington team identified a new set of toxic chemicals in everyday consumer products. That’s important because it gives us an opportunity to reduce exposure to toxic chemicals and prevent their release into the environment. We want your feedback on the products we’ve identified as significant sources of these toxic chemicals.
In both the 2022 Supplemental Operating and 2023 Operating budgets, the Washington State Legislature provided funds to Ecology to work on issues related to 6PPD. As part of this work, the Legislature requested that Ecology provide a progress report on the Action Plan and Alternatives Assessment by December 31, 2024.
As part of the U.S. Environmental Protection Agency’s commitment to safeguard the environment from per- and polyfluoroalkyl substances (PFAS), the agency uses its Clean Water Act authorities to develop recommended water quality criteria and informational benchmarks to help states and authorized Tribes protect aquatic ecosystems from several PFAS.
This new Interstate Technology and Regulatory Council (ITRC) document provides information about 6PPD and 6PPDQ that can help inform future policies and regulations. The guide provides:
An introduction to 6PPD and 6PPDQ.
Current knowledge of effects, toxicity, and physical/chemical properties of 6PPD and 6PPDQ.
The occurrence, fate, and transport of 6PPD and 6PPDQ in the environment.
An overview of measuring, mapping, and modeling techniques for these chemicals.
Discussion of mitigation measures, solutions, policies, regulations, and laws.
An overview of information gaps and research needs.
CNN — There are chemicals in cookware, food, water, clothes and furniture that could cause problems for people’s health.
These PFAS, or perfluoroalkyl and polyfluoroalkyl substances — sometimes called “forever chemicals” because they don’t fully break down in the environment — have been used in consumer products since the 1950s.
