Toxics studies

Our scientists analyze and measure many types of toxic contaminants from a variety of places. We study the impacts of toxic releases on air quality, water, sediment and fish, in specific watersheds, and in consumer products.

• Testing for chemicals in consumer products
• Product testing database
• Product testing reports and publications

Water, sediment, and fish

• Groundwater quality assessment includes some studies of toxics in underground aquifers.
• Toxics monitoring projects address persistent, bioaccumulative, and toxic chemicals in water, sediment, and fish.
• Sediment quality in urban bays reports on toxic contaminants in marine environments near populated areas.

Toxics initiatives by watershed

• Green-Duwamish watershed pollutant loading assessment
• Toxic chemicals in Puget Sound
• Yakima watershed toxics reduction project
• Improving the Spokane River
