Spokane, Washington, has faced challenges with air quality, primarily due to particulate matter (PM) pollution from sources such as vehicle exhaust, industrial emissions, and wood burning. This guide aims to provide a comprehensive understanding of Spokane's air quality, its causes, and effective strategies to improve it.
PM is a major concern for Spokane's air quality. PM2.5, particles with a diameter of 2.5 micrometers or less, are particularly harmful as they can penetrate deep into the lungs and cause respiratory issues. According to the American Lung Association, Spokane ranked 11th among all U.S. cities for short-term PM2.5 pollution in 2021.
The primary sources of PM pollution in Spokane include:
Exposure to PM pollution can lead to a range of health problems, including:
