The Bay Area Air Quality Management District issued for Saturday yet another Spare the Air Alert for smog, the seventh this year and for the third straight day.
According to its official release, the district said air quality in the Bay Area is forecast to be unhealthy again.
There is no free transit and no wood burning ban in place. The Air District recommends residents avoid outdoor activities during the hottest part of the day, when air quality is unhealthiest.
"High temperatures and low winds are continuing in the Bay Area, prolonging conditions that are unfavorable for air quality," said Jack Broadbent, executive officer of the Air District. "Bay Area residents should continue to take action to safeguard their health and reduce pollution levels in the region."
The Air District encourages the public to re-think their commute by taking transit, carpooling, working from home or biking and leave their car at home twice a week to avoid air pollution that builds up and creates unhealthy smog when the Bay Area experiences high temperatures.
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.
Smog is formed when volatile organic compounds and nitrogen oxides from motor vehicle exhaust, gasoline vapors, industrial emissions and household chemicals combine with oxygen in the presence of heat and sunlight.
Residents can help Spare the Air by carpooling, taking transit, switching to an electric vehicle, biking or walking. Visit sparetheair.org or 511.org for more information about commute alternatives.
