Last month’s review

Springtime is when we have our best air quality! Pollution was at its lowest level in April since last summer.

The air monitor in the Chinatown-International District showed 4 “moderate” days and 26 “good” days last month.

The main sources of air pollution in the neighborhood are cars and trucks driving on I-5 and I-90. Unfortunately, people living along major roadways in King County are more likely to be low-income and of a minority race.

Did you know?

Air pollution is usually worse in the morning than in the afternoon. We usually get windier conditions and more air mixing as the day goes on.
