Air District Issues First Spare the Air Smog Alert in 2019


SAN FRANCISCO – The Bay Area Air Quality Management District is issuing the first Spare the Air Alert for smog in 2019.

Air quality is forecast to be unhealthy on Sunday, June 9. High inland temperatures combined with light winds and motor vehicle exhaust is expected to cause unhealthy ozone accumulation in the region. There is no free transit tomorrow and there is no wood burning ban in place.

“Air pollution from the millions of vehicles on Bay Area roadways, in combination with hot temperatures, is expected to create unhealthy air quality in our region,” said Jack Broadbent, executive officer of the Air District. “Leaving our cars at home and walking, biking or taking transit, instead of driving alone, will help reduce unhealthy air pollution so we can all breathe easier.”

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. Long-term exposure to ozone can reduce lung function. Ozone pollution is particularly harmful for young children, seniors and those with respiratory and heart conditions. When a Spare the Air Alert is issued, outdoor exercise should be done only in the early morning hours when ozone concentrations are lower.
