Last month’s review

Air quality was “good” for most of November in the Chinatown-International District. There were
seven “moderate” air quality days, the same as October. Overall, the neighborhood’s air quality was similar to most areas in South Seattle.

Air pollution in the neighborhood comes mostly from cars and trucks on I-5 and I-90.

Pollution from trucks is harmful to health and can lead to heart attacks, strokes, and cancer.

Looking ahead to winter

Our highest pollution levels occur in the winter months when the air becomes calm and clear. Fortunately, it’s often rainy and windy in the winter, which is good for air quality!
