Ozone, or smog, is a dangerous pollutant that poses a serious threat to human health. It is not emitted directly into the air, but rather is created through a chemical reaction. Nitrogen oxides (NOx) and volatile organic compounds (VOCs) combine in the air and are heated by the sun to form ozone.
Sources of NOx and VOCs include: petrochemical refineries, chemical plants, construction equipment, power plants, breweries, restaurants and bakeries, dry cleaners, marine vessels, planes, trains, and automobiles. And yes: trees and plants also emit some of these chemicals.
In Houston, weather conditions are often perfect for the formation of ozone. Ozone is formed on warm, sunny days with little to no wind and no rain. The sea breeze coming from the Gulf of Mexico moves ozone pollution around the Houston region. Early morning winds come from the Northwest carrying pollution from the Houston Ship Channel (where large concentrations of NOx and VOCs have been measured) and push these pollutants out to sea. When the afternoon temperature heats up, the winds switch direction and move clockwise, carrying pollution north of the city. The Texas Commission on Environmental Quality (TCEQ) has measured high ozone levels in areas like Fort Bend County.
