... 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, 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 WOOD STOVE BUT A LOT
OF PARTICLES FORM WHEN GASES REACT IN THE AIR. NITROGEN OXIDES AND
SULFUR OXIDES 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 DUST STORMS
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.
