SAN JOAQUIN VALLEY - Valley Air District officials urged residents to consider their health and that of their neighbors when planning to use household fireplaces during the holiday season.
"Share the good cheer of the holidays, not wood smoke," said Seyed Sadredin, Air District director. "The fires that seem so cozy and inviting can actually cause your neighbors distress."
Residential wood burning can produce up to 24 tons per day of harmful particulate matter (PM) across the valley on a winter day. PM is made up of soot, ash, tiny droplets of liquid and other material.
