2010 already twice as smoggy as 2009

Augusta recorded its second unhealthy air episode of the year this week after surviving all of 2009 without a single violation.


The U.S. Environmental Protection Agency's standard for ground-level ozone -- smog's main ingredient -- sets a limit of 75 parts per billion over an eight-hour average.

Wednesday's reading of 77 parts per billion was the second violation this year. On July 9, an eight-hour average of 81 parts per billion was recorded.

Although there were no violations in 2009, there were four in 2008, three in 2007, four in 2006 and one in 2005, according to Georgia's Environmental Protection Division.

Typically, the region's most unhealthy air accompanies the stifling heat and humidity of late July and August.

The current standard of 75 parts per billion is stricter than an earlier standard of 85 parts per billion. A proposal is under way to tighten the levels even more -- to a range of between 60 and 70 parts per billion to better protect public health.

According to the American Lung Association, ozone is formed by chemical reactions of nitrogen oxides and hydrocarbons, also called volatile organic compounds. They are produced primarily when fossil fuels such as gasoline, oil or coal are burned or when some chemicals, such as solvents, evaporate. They combine with heat and sunlight to form ozone smog.

People vary widely in their susceptibility to ozone. Healthy people, in addition to those with respiratory difficulty, can experience breathing problems when exposed to ozone. Exercise during exposure to ozone causes a greater amount of ozone to be inhaled and increases the risk of harmful respiratory effects.

Other Georgia cities and regions have also had ozone violations this year, including 10 in metro Atlanta, four in north Georgia, two each in Macon and Athens and one in Columbus.

Reduce emissions

According to the Clean Air Campaign, an environmental group, there are several ways Augusta residents can reduce emissions that create smog:

CARPOOL: The Clean Air Campaign helps commuters find partners for their commute to save money and enjoy a stress-free commute

VANPOOL: Kick back and relax while you enjoy company with friends during your drive to work

TRANSIT: Augusta Public Transit passes can cost as little as $25 a month.

TELEWORK: Avoid traffic and increase your productivity by 10-20 percent by working from home. The Clean Air Campaign can talk to your employer about telework benefits and the help start a telework program at your office

BIKE OR WALK: Nearly 25 percent of our trips are less than one mile, switch up your commute and try a healthier option

REARRANGE YOUR WORK SCHEDULE: Adjust your commute and drive to work at off-peak times to avoid sitting in traffic and polluting the air. You can also try working a compressed work week to avoid driving to work one day a week
