Seattle’s air quality is getting worse
Change in air quality, by metro area: Across metro areas in the U.S., from 2014-16 to 2021-23, air quality improved in 62% while worsening in the remaining 38%. This information is based on data sourced from the EPA.
Seattle’s escalating air pollution: Over the recent decade, the city has experienced a 17% spike in fine particle pollution according to the Environmental Protection Agency (EPA).
Why it matters: The adverse effects of air pollution on health cannot be understated. Apart from the obvious respiratory complications, it’s linked to increased dementia risk and poor reproductive outcomes as revealed in various studies.
By the numbers: Fine particle pollution in Seattle escalated from 6.28 to 7.4 micrograms per cubic meter between 2014-16 and 2021-23.
Zooming into Seattle’s pollution issue: An industry expert revealed that air pollution in Seattle is 10% higher than other similar-sized U.S. cities. He ascribes this primarily to industrial activity and transportation corridors, with fossil fuels playing a substantial role. The expert’s insights were also aired on KIRO Newsradio.
Air pollution drivers in Seattle:
- Industrial and transportation sectors are the main contributors.
- Hammes predicts a future rise in pollution, if unchecked.
The big picture: While fine particulate matter (PM2.5) serves as a significant air pollution indicator, it doesn’t cover all aspects of air pollution.
Staying safe: Regularly checking the local Air Quality Index and trusting one’s senses are essential in assessing air pollution.
