September and October’s Review
We mostly had “good” air quality these last two months at our neighborhood air monitor. Only four days measured in the “moderate” range during that time, mostly due to all the rain in October. 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.
Did you know?
On September 15, gas stations switch to a “winter gas,” which is cheaper, but pollutes the air more. Winter gas is less dense and can more easily escape into the air. But the lighter winter gas can help start a car on those icy cold mornings.
