As noted above, high PM2.5 concentrations in the San
Francisco Bay Area nonattainment area occur primarily during the
winter months and, therefore, the BAAQMD submitted a winter
season inventory. The high winter concentrations are mainly due
to meteorological factors, but also are affected by increased
residential wood burning during the winter. In addition, cool
weather promotes the formation of ammonium nitrate. Residential
wood burning and diesel vehicles comprise about two thirds of
the directly emitted PM2.5 emissions. On-road motor vehicles make
up the largest source of NOx and VOC emissions.

Residential wood heating accounts for almost half of the winter
directly emitted PM2.5 emissions, and mobile sources are the
largest contributors to NOx emissions.
• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
