June 09--Commuters were urged to avoid driving in the Bay Area on Monday as air quality authorities issued a Spare the Air Alert for the second day in a row.
Monday's alert was the fifth in 2014 so far as the Bay Area Air Quality Management District once again prepares for unhealthy levels of smog around the region.
"The No. 1 thing residents can do is to leave their cars at home. Try transit, carpooling, walking or biking to work instead," said district spokeswoman Kristine Roselius.
High temperatures and low winds, coupled with vehicle exhaust, are to blame for the nasty ozone-polluted air.
Ozone pollution hits kids the hardest, along with those who are active outdoors, by reducing lung function and damaging the lining of the lungs.
"To protect residents' heath, we recommend people avoid outdoor exercise during the hottest part of the day," Roselius said.
During the morning and afternoon commute, Roselius said, the smog isn't as bad, but once the heat hits stagnant vehicle exhaust, it starts settling around the area. The Livermore and Santa Clara valleys are expected to be hit the hardest.
