Seattle and Tacoma Air Toxics Study

We invite you to share your input on air monitoring in Seattle's Duwamish Valley

Starting in the fall of 2021, the Puget Sound Clean Air Agency will be measuring a type of air pollution called air toxics in Seattle and Tacoma. Air toxics are a group of over 400 pollutants known or suspected to cause several health problems; including cancer and birth defects, as well as damage to lungs, immune systems, and nervous systems.  

This study will gather important air quality data and help us better understand the health risks associated with air pollution. This study will look at changes in air toxics levels over time including diesel exhaust sources, wood smoke, and metal emissions in industrial areas. We will estimate potential cancer risk from these air toxics.

Air Toxics in the Duwamish Valley

One area where we will be placing monitors is in Seattle’s Duwamish Valley and there is an opportunity for community-directed monitoring. This part of the study will include community members in the process of identifying locations of interest in the Duwamish Valley. 

The study aligns with goals set by the Duwamish River Cleanup Coalition’s Clean Air Program. Recently – in a separate study – the Duwamish Valley Youth Corps partnered with the US Forest Service, and others to look at heavy metals found in moss on street trees. It’s impossible to translate the results from the moss to human health risk without air sampling, which this study will help do.  

We Invite You To Share Your Input!

We want to include your input on where to monitor for air toxics in the Duwamish Valley.  

Workshop

On Tuesday, August 17th, we will host a workshop in collaboration with the Duwamish River Clean-Up Coalition in South Park. We will introduce information on air toxics, share recent moss study results, and hear your valuable input. DRCC Logo
