The season's second "Winter Spare the Air Alert" has been issued for Thursday, by the Bay Area Air Quality Management District.
District officials anticipate high levels of pollution this week and said that wood burning, both indoors and outdoors, will be illegal.
"Winter air pollution is mainly caused by particulates or soot pollution from wood smoke," district officials said in a statement. "Smoke from wood-burning fires is linked to illnesses such as asthma, bronchitis and lung disease, and is especially harmful for children and the elderly."
The district's Winter Spare the Air season began Nov. 1 and will end on Feb. 29. Residents are advised to check www.sparetheair.org or call 877-4-NO-BURN to check the daily burn status.
