Air Quality Isn't Just an Issue for Big Cities

Lawrenceville is also in the peak seasons for higher levels of ground-level ozone — May to September.

Ground-level ozone is a product of "cooking," a type of cooking far less enticing than the kind that can results in tasty foods. Instead, sunlight and warm temperatures “cook” compounds in the air, which react to form pollution that poses risks to our health and the environment. 

Where do these compounds — nitrogen oxides (NOx) and volatile organic compounds (VOCs) — come from? 

Nitrogen oxides come primarily from combustion of fuels in cars and trucks, coal-fired power plants, industrial boilers and gas-powered engines such as lawnmowers and leaf blowers.

Volatile organic compounds are vapors from paint and print shops, gas stations, dry cleaners, lawn chemicals and from combustion engines, such as those in cars and trucks, boats and diesel locomotives. Trees also emit VOCs.

With its crazy levels of traffic, one might think Atlanta would be the cesspool for nasty pollutants, but ozone-forming pollution can be swept long distances by the wind before reacting in the sun. Barrow County can be impacted by emission sources — those vehicles, coal-fired power plants and other sources — from hundreds of miles away.

While ground-level ozone is a health and environmental concern, ozone in the stratosphere, which is six to 30 miles above Earth, is beneficial, shielding us from harmful ultraviolet radiation.
