| April 28, 2008 Smoke from
the Sierra Madre wildfire burning in the San Gabriel Valley area of Los
Angeles County is forecast to create unhealthy air quality today in the
eastern San Gabriel Valley area of Los Angeles County.
All individuals are urged to exercise caution and avoid unnecessary
outdoor activities in the smoke-impacted area and areas that can see and
smell smoke.
Wildfires generate smoke containing fine particulates known as PM10 and
PM2.5. Concentrations of fine particulates may reach the
Unhealthy-Sensitive or higher level in the smoke impacted areas.
What to Do When Air Pollution Reaches Unhealthy Levels
In areas with UNHEALTHY-SENSITIVE air quality, sensitive or
susceptible persons, such as those with heart or lung disease, should
minimize outdoor activity.
In areas with UNHEALTHY air quality, everyone should discontinue
prolonged, vigorous outdoor exercise lasting longer than one hour. Examples
of the kinds of outdoor activities that should be avoided are calisthenics,
basketball, running, soccer, football, tennis, swimming laps, and water
polo. Susceptible persons, such as those with heart or lung disease, should
avoid outdoor activity entirely.
For more tips on avoiding health impacts from the smoke, see

AQMD is the air pollution control agency for Orange County and major
portions of Los Angeles, San Bernardino and Riverside counties.
