Last month’s review

Thanks to the breezy weather, we had a clean May, with 30 “good” air quality days and only one in the “moderate” range. Air pollution in the Chinatown-International District mainly comes from cars and trucks. Over 250,000 vehicles, including 20,000 trucks, drive by on I-5 and I-90 each day. Air pollution can have serious impacts on human health, such as heart attacks, strokes, asthma and more.

Did you know?

Not only is transportation with cars, trucks, trains, and boats the largest source of toxic air pollution in our region, it is also our number one source of greenhouse gases that change our climate over time.
