Code Orange air quality day prompts action
RALEIGH – Air quality officials issued a health notice for air pollution in the Charlotte, Fayetteville and Triangle metropolitan areas today. Forecasters have predicted Code Orange conditions, which means that air quality in these areas is likely to be unhealthy for sensitive groups.
This forecast means people who are sensitive to air pollution should avoid moderate exertion outdoors in the afternoon. Sensitive groups include children and the elderly who are active outside, people who work
or exercise outdoors, and those with asthma, bronchitis, emphysema and other respiratory ailments.
The primary pollutant of concern is ozone, a highly reactive form of oxygen. Ozone can be unhealthy to breathe, damage plants and reduce crop yields. High ozone levels generally occur on hot sunny days with stagnant air, when pollutants such as nitrogen oxides and hydrocarbons react in the lower atmosphere.
The air pollution forecast for today predicts that ozone levels will exceed the new federal standard of 0.075 parts per million (ppm) averaged over 8 hours. High ozone levels can impair breathing and aggravate symptoms in people with respiratory problems, and irritate the lungs in healthy individuals. People with chronic lung ailments, the
elderly and children should reduce physical exertion and outdoor activity in the afternoon, when ozone levels are highest.
The N.C. Division of Air Quality issues daily air forecasts for the Triangle, Charlotte, Asheville, Hickory, Fayetteville and Rocky Mount metropolitan areas.
Officials are asking residents to help reduce air pollution by taking some of the following
* Limit driving by riding the bus, walking, bicycling or postponing trips.
* If you drive, avoid idling for long periods of time, stay within speed limits, combine errands to reduce the number of small trips, and use vehicles with higher fuel economies.
* Conserve electricity by setting thermostats at the highest comfortable temperature and turning off appliances that are not in use.
In addition, residents of affected areas should refrain from outdoor burning on Code Orange and Red days. It is always illegal to burn paper, trash, construction materials and other non-vegetative matter in
The DAQ estimates that more than half of North Carolina’s citizens live in counties where ozone levels exceed the standard during warmer months.
In 1999, the N.C. General Assembly passed legislation aimed at reducing ozone-forming emissions from cars and trucks, including an expansion of the motor vehicle emissions inspection program from nine to 48 counties.
In 2002, the General Assembly enacted legislation that will require the state’s coal-fired power plants to reduce their ozone- and haze-forming emissions by three-fourths over the next decade.
