Ground level ozone:
Ground level ozone is the ozone present at the lower level of earth atmosphere. It is not emitted directly into the environment but produced by complex chemical reaction, when nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOC'S) react in presence of sunlight. NOx and VOC's are called ozone precursors and produced from cars, trucks, electric power plants, paint's fumes and industrial process.
