AQI Forecasts Can Help You Protect Yourself
•	You're exposed to poiiution any time you breathe polluted air. But
when you exercise, do yard work or other strenuous activities that
increase your breathing rate, you take more pollution into your lungs.
•	You can reduce your exposure by using AQI forecasts to help you
plan your day. When the forecast calls for elevated levels of pollution,
protect your health by reducing your exposure - especially if you are
in a sensitive group.
•	Take it a little easier. You can cut back on strenuous activities (e.g., go
for a walk instead of a jog). Or reschedule strenuous activities for times
when air quality is expected to be better. It's a small change that can
help you protect your lungs and heart.
Where Can You Find Your Local AQI Forecast?
•	Many local television stations,
radio stations and newspapers
carry local AQI forecasts.
•	You also can find your local
forecast by logging on to
EPA's AIRNow web site at
www.epa.gov/airnow.
Groups sensitive to the
effects of air pollution:
Particle Pollution
People with heart or lung
disease (such as asthma),
older adults, and children
Ground-level Ozone
People with lung disease (such
as asthma), and children and
adults who are active outdoors.

As Important As Checking The Weather
• You probably check the weather forecast every day. After all, it's a
useful tool that helps you plan what to wear and lets you know if
you need to carry an umbrella.
• But there's another forecast out there you should be checking, too.
This forecast, known as the Air Quality Index (AQI) forecast, can
help you plan your activities to protect your health.
• in less than a minute each day, this important tool lets you know:
what today's air pollution levels will be in your community;
who's at risk from that pollution; and
simple steps you can take to protect yourself.
• You may have seen AQI forecasts for ozone. In nearly 300 cities
across the country, state and local air pollution agencies issue
these forecasts during the summer, when ozone can be a problem.
• Ozone aggravates asthma and other respiratory diseases, and can
make it difficult for you to breathe as deeply as you normally would.
Ozone also can permanently change the structure of your lungs.
• But ozone isn't the only type of pollution that can affect your health.
Particles in the air also can affect your lungs - and your heart. So
EPA, in cooperation with state and local air agencies, is making AQI
particle pollution forecasts available in many U.S. cities.
Particle Pollution Forecasts Begin Fall 2003
•	Starting in October, more than 100 U.S. cities will issue AQI forecasts
for "particle pollution" - microscopic particles in the air that can get
deep into the lungs - potentially causing serious health problems.
•	Particle pollution comes from a wide range of sources, from power
plants and industry, to cars, trucks and buses, to wood stoves and
forest fires. Some particles are released when fuels burn. Others
form in the atmosphere, from reactions between gases released
from power plants and factories.
•	Unlike summertime ozone, particle pollution can occur year-round
- and that means it can affect your health year-round.
•	Particles can affect both your respiratory system and your heart.
Particle pollution has been linked to a number of health problems
ranging from asthma attacks to heart attacks - and even early
death in people with heart or lung disease.
•	You can reduce your exposure to particle pollution by acting on the
AQI forecast for your area. These forecasts, available all year, will
use the familiar color-coded scale to let you know about the next
day's particle levels. In the summer, you may see forecasts for both
particle pollution and ozone.
•	Meteorologists in state and local air quality agencies develop AQI
forecasts using actual air quality data along with weather forecast
information.
Are You At Risk?
•	Air pollution can affect everyone, and it can be especially harmful
for certain groups of people. Check the box on the back of this
page to see if you're in one of these groups.
•	Don't assume that you're safe just because you're healthy. At
elevated levels, particle pollution and ground-level ozone can be
a threat to everyone's health. For more information, go to
