Ozone is in the air. Ozone is both a good guy and a bad guy depending on where in the air it shows up. Ozone is good up high, bad nearby.
Ozone in the stratosphere provides a protective ozone layer that protects the earth from UV radiation. At that level ozone depletion or ozone holes are bad.
Ozone lower in the atmosphere, at ground level in the air we breathe, is a pollutant. It is a health hazard and it can harm plants as well.
Air Quality and Ozone Pollution
Emissions from vehicles is the largest source of ground-level ozone in Texas. That's why the City of Tyler encourages the use of public transporation and other methods of transportation that reduce the number of cars and trucks on the road.
Ozone pollution makes breathing very difficult for some people. It aggravates asthma and can cause respiratory distress and infections. Ozone pollution affects plant life as well, killing trees and interfering with food crops.
The federal government has set certain standards for air quality, including acceptable and unacceptable ozone levels.
Q. What Are Ozone Action Days?
Ozone Action Days are specific days during ozone seaons when ground-level ozone is expected to exceed pre-determined levels. Ozone season is that time of year when ground-level ozone is most likely to form - hot, sunny, wind-free days. Ozone levels typically peak in the hotter days of August and September. Ozone season can vary by a month or so in either direction in different parts of Texas. For example, ozone season is 9 months long in Houston.
