THIS IS AN OPPORTUNITY TO LEARN MORE ABOUT AIR QUALITY AND HOW IT AFFECTS YOUR HEALTH. THERE ARE TWO TYPES OF AIR POLLUTION: OZONE AND PARTICLE POLLUTION. THESE ARE TWO COMMON POLLUTANTS FOUND IN MANY PARTS OF THE COUNTRY. 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. NOW WE WILL 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 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 DURATION...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.
