Continuing hot weather has prompted the Bay Area Air Quality Management District to call more Spare the Air alerts for Wednesday and Thursday, Sept. 9 and 10.
The hot weather combined with light winds are expected to lead to more smog from vehicle exhaust, so residents are encouraged to walk, bike, take public transit or carpool in an effort to reduce pollution.
The heat wave is expected to persist throughout the week, so more Spare the Air alerts could be coming.
Smog can lead to health hazards like throat irritation, congestion and chest pain. People suffering respiratory conditions such as asthma, bronchitis and emphysema, could have their conditions aggravated, according to the air district.
