Last month’s review
February was unusually warm and sunny, but with calm winds. As a result, the month had the second highest levels of air pollution since we started monitoring in the Chinatown-International District last June. February had 12 “moderate” days and 16 “good” days.
The main sources of air pollution in the neighborhood are cars and trucks driving on I-5 and I-90. Breathing high levels of this pollution can cause heart attacks, strokes, asthma attacks, and more.
Next few months
Now that spring is here, we should have plenty of wind and some of our cleanest air of the year.
