Another Spare the Air alert for Wednesday

SAN FRANCISCO (KRON) — With the Bay Area in the midst of an end of summer heat-wave, air quality officials issued another Spare the Air alert on Wednesday, for what will be the second straight day.

The Bay Area Air Quality Management District said a high pressure system over California will continue to produce clear skies, light winds and triple-digit inland temperatures. These conditions, combined with motor vehicle exhaust, will produce unhealthy ozone levels, air quality officials said.

“This week’s heat wave is causing unhealthy air throughout the Bay Area,” said Jack Broadbent, executive officer of the Air District. “In order to keep the air we breathe healthy and reduce greenhouse gas emissions, it will be critical to reduce the number of people driving alone in their cars and get them to regularly use public transportation, carpools and other more climate-conscious commute modes.”

Wednesday’s Spare the Air day will be the sixth such alert so far in 2015, according to air district officials.

“Motor vehicle exhaust is the number one source of smog-forming pollution, so we’re asking Bay Area residents to share rides, take transit, bike or walk to help keep pollution levels down,” Broadbent said in a statement.

Smog can cause throat irritation, congestion and chest pain. It can also trigger asthma by inflaming the lining of the lungs, and exacerbate other respiratory conditions like bronchitis or emphysema, according to air district officials.

Almost 40 percent of smog pollution in the Bay Area comes from passenger vehicles, according air quality officials.

District officials are asking residents to do their part to help the region’s air quality. They’re encouraging residents to walk, bike, carpool or take transit instead of driving alone, not just on Spare the Air days but every day.
