BAY AREA, CA - Scorching inland temperatures and tailpipe exhaust continued to hamper air quality in the Bay Area on Saturday, prompting officials to extend a Spare the Air Alert through Sunday, officials said.
The triple-digit heat wave bearing down on much of the region is expected to combine with vehicle exhaust to create unhealthy levels of smog for the rest of the weekend, including Monday, officials said.
Such alerts are issued when ozone pollution has the potential to reach unhealthy levels, officials said. Ozone and elevated smog is known to cause throat irritation, congestion, chest pain and can trigger asthma. Smoke can also inflame the lining of the lungs and worsen bronchitis and emphysema. Long-term exposure can reduce lung function.
The air district urges anyone planning to do strenuous activities to do so in the early morning hours when ozone concentrations are lower.
In the event of a wildfire, if the smell of smoke is present, Bay Area residents are urged to head inside and close the windows and doors until the smoke clears. Residents can find air quality readings here.
People can find out when a Spare the Air alert is in effect by registering for the alerts at www.sparetheair.org, calling 1(800) HELP-AIR, downloading the Spare the Air smartphone app or connecting with Spare the Air on social media.
