THIS IS AIR QUALITY AWARENESS WEEK. THIS IS AN OPPORTUNITY TO LEARN
MORE ABOUT AIR QUALITY AND HOW IT AFFECTS YOUR HEALTH.

TODAY WE HIGHLIGHT THE CAUSES OF POOR AIR QUALITY. AIR QUALITY CAN
VARY DEPENDING ON HOW MUCH AIR POLLUTION IS PRODUCED IN YOUR
COMMUNITY AND HOW MUCH POLLUTION IS CARRIED INTO YOUR COMMUNITY BY
THE WIND AND BY WEATHER CONDITIONS. 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. NITROGEN OXIDES AND SULFUR DIOXIDES
CONTRIBUTE TO PARTICLE FORMATION.

THESE OZONE AND PARTICLE FORMING POLLUTANTS COME FROM A WIDE 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
POLLUTION.

WEATHER PLAYS A BIG ROLE IN THE LEVELS OF OZONE AND PARTICLE
POLLUTION IN YOUR COMMUNITY. SUNLIGHT AND HEAT PROMOTE OZONE
FORMATION. LIGHT WINDS AND TEMPERATURE INVERSIONS CAN KEEP POLLUTION
CONCENTRATED NEAR THE GROUND.  DEPENDING ON ITS DIRECTION, THE WIND
CAN BRING IN MORE POLLUTION... SOMETIMES FROM HUNDREDS OF MILES
AWAY. GEOGRAPHY CAN AFFECT POLLUTION LEVELS TOO.  MOUNTAIN RANGES
CAN PREVENT POLLUTION FROM DISPERSING.

TOMORROW WE WILL LEARN ABOUT THE HEALTH IMPACTS OF POOR AIR QUALITY.
