MODERATEAt this level the air is probably safe for most

people. However, some people are unusually

sensitive and react to ozone in this range,

especially at the higher levels (in the 80s and

90s). People with heart and lung diseases

such as asthma, and children, are especially

susceptible. People in these categories, or

people who develop symptoms when they

exercise at "yellow" ozone levels, should

consider avoiding prolonged outdoor exertion

during the late afternoon or early evening

when the ozone is at its highest.

UNHEALTHY FORSENSITIVE GROUPSIn this range the outdoor air

is more likely to be

Children, people who are

sensitive to ozone, and

people with heart or lung

disease should limit

prolonged outdoor exertion

during the afternoon or

early evening when ozone

levels are highest.

Southern Californians live in some of the most polluted communities in the nation. Below is a guide from the US EPA describing who is impacted as air pollution increases.
