Smog that’s expected Tuesday led air quality officials Monday to call to a pollution alert across a large swath of Solano County.
The Bay Area Air Quality Management District projects air quality Tuesday in the district’s Eastern Zone that’s unhealthy for people who are sensitive to air pollution – such as people with asthma or some other condition that affects their ability to breath freely.
Southern Solano County, to include Fairfield, Suisun City, Travis Air Force Base, Benicia and Vallejo, are in the district’s Eastern Zone. Air quality should remain moderate throughout the district ’s remaining four zones, according to the district, but residents there will still be under a Spare the Air alert.
Residents in the Yolo-Solano Air Quality Management District should see moderate air quality Tuesday, based on forecasts in that district.
The Yolo-Solano district includes northern Solano County along with Vacaville, Rio Vista and Dixon.
Summertime Spare the Air alerts are issued when ozone pollution is forecast to reach unhealthy levels. Ozone, or smog, can cause throat irritation, congestion, chest pain, trigger asthma, inflame the lining of the lungs and worsen bronchitis and emphysema, according to the air district. Long-term exposure to ozone can reduce lung function, the district said.
Solano County residents weathered three consecutive days of air pollution alerts early this month. Last summer’s first Spare the Air alert occurred in late July.
The National Weather Service predicts a high Tuesday of 94 at Travis Air Force Base, with winds from the west-southwest of 7 to 9 mph during the day.
High temperatures and pollution from the exhaust of cars and other vehicles combine to produce smog, which lingers when winds are not strong enough to clear the air.
