The Bay Area Air Quality Management District declared a Spare the Air Day today for the third consecutive day, indicating that air pollutants exceed state and federal standards and it could be unhealthy to breathe.
"On these Spare the Air days, we urge residents to cut back on any activities that cause pollution - such as driving, using oil-based paints, gasoline-powered lawn mowers, or household aerosol products like hair sprays," according to the air district's web site.
The air district is a public agency that regulates air pollution.
Summer months through mid October tend to generate a smoggy environment from the temperature and lighter-than-usual winds prevail.
