Ozone Season Begins April 1

March 29, 2012 [MARICOPA COUNTY] - The Valley enters its official ozone season on April 1, and does not conclude its watch for the ground level pollutant until the end of September.  The pollutant is making an early season debut as air quality forecasters issued an ozone health watch Thursday.

Ozone pollution is granted a summertime status due to its need for interaction with heat and sunlight.  Ground level ozone forms when emissions from fossil-fuel fired equipment, industrial and chemical processes, and even household activities react with heat from the sun.

The year 2011 was shaping up to be a clean year for the region’s air quality, but Mother Nature had other plans. Twenty-three days had exceedances of the federal ozone health standard and the Arizona Department of Environmental Quality issued 11 high-pollution advisories and 29 health watches for ozone during 2011.

 

“Ozone pollution is a very real concern that can easily be reduced through small, every day actions, but everyone must take part,” explains Maricopa County Air Quality Department Director Bill Wiley.  “Choosing to refuel after dark, avoiding drive-thru lines or even switching to CFL bulbs, can reduce ozone concentrations.”

Ground level ozone pollution is a direct threat to your lungs and can trigger asthma. Children are at the greatest risk from ozone because their lungs are still developing, they are most likely to be active outdoors, and they are more likely than adults to have asthma. Adults with asthma or other lung diseases, and older adults are also sensitive to ozone.

Ozone pollution prevention tips:  

 

·              Avoid waiting in long drive-thru lines, for example, at coffee shops, fast-food restaurants or banks. Park your car and go inside.

·              Refuel your vehicle after dark or during cooler evening hours.

·              Drive less. When possible, carpool, van pool or use public transportation.

·              Use low-VOC (Volatile Organic Compounds) or water-based paints, stains, finishes and paint strippers

·              Delay big painting projects until high-pollution advisories or health watches have passed.

·              Make sure containers of household cleaners, garage and yard chemicals and other solvents are sealed properly to prevent vapors from evaporating into the air.

·              Conserve electricity.

OZONE BACKGROUND:  Ground level ozone is formed by a chemical reaction that needs heat from sunlight, nitrogen oxides and volatile organic compounds [VOCs] to form. The months of April through September make up the Valley’s longer-than-normal “ozone season.”
