Last month’s review

For the month of January, air pollution in the Chinatown- International District neighborhood was the highest since we started monitoring there in June 2014. We had 16 “moderate” days and 15 “good” days last month. Overall, the neighborhood’s air quality was similar to most areas in S. Seattle. Air pollution in the neighborhood mostly comes from cars and trucks on I-5 and I-90. Breathing high levels of this pollution can cause heart attacks, strokes, asthma attacks, and more.

Next few months

Winter has the highest pollution levels of the year. With spring on its way, we should have more wind and our cleanest air soon.
