... Air quality awareness week is April 27-may 1...
Next week Marks the beginning of ozone season for many areas in
the United States.
The goal of air quality awareness week is to provide information on
outdoor air pollution and its impact on the quality of the air we
breathe. Noaa's National Weather Service (nws) is partnering with
the U.S. Environmental protection agency (epa) and the U.S.
Centers for disease control and prevention (cdc) to meet this goal.
Poor air quality impacts our health. To learn more about poor air
quality... air quality forecasts... alerts and safety tips to help

Today we highlight two types of air pollution: ozone and particle
pollution. These are two common pollutants found in many parts of
Ozone is a colorless odorless gas. It is the same gas that is found
in the ozone layer... high in the earth's stratosphere... where it
protects US from the sun's ultraviolet energy. But at ground level
where we live... ozone pollution is unhealthy to breathe.
Particle pollution... or airborne particle pollution... consists of
microscopic particles in the air. Depending on where you live... it
can be a problem in the winter and/or Summer. Like ozone... particle
pollution is not healthy to breathe. The particles also contribute
to haze which blurs The View in many cities and National Parks.
Ozone forms when two groups of key pollutants... nitrogen oxides and
volatile organic compounds... Cook in the sun. Particle pollution can
be directly emitted for example in smoke from a woodstove... but a
lot of particles form when gases react in the air.
These ozone and particle forming pollutants come from a variety of
sources... including cars... trucks... buses... power plants... and
industries. Natural sources such as wildfires and duststorms
contribute to particle pollution. Trees and other vegetation also
Emit organic compounds that contribute to particle and ozone
Exposure to high levels of ozone and particle pollution is linked
with a number of significant health problems. Children... people with
lung disease... older adults and people with heart disease tend to be
more vulnerable. When pollution reaches high enough levels... the air
can be unhealthy for everyone... especially if you are active
Sunday's topic will cover air quality forecasts and safety tips to
mitigate poor air quality.
