Houston Clean Air Network

Did you know that Houston is likely to have high ozone days in late spring and early summer?

Did you check the ozone level at Eleanor Tinsley Park before your ran today?

Bring Ozone Theater or Air Pollution Solutions to your school. Our interactive program will teach your students about ozone and the health effects of pollution.

What is Ozone?

What does it mean when the weather reporter says it’s going to be a “bad ozone day”? Or when a doctor says that “sensitive groups” should avoid outdoor activities? Generalizations like these can be confusing and frustrating as you plan your day...Read More

Tropospheric and Stratospheric Ozone

Perhaps the most common misunderstanding about ozone comes from the fact that, in certain places, ozone is essential to life. When ozone is high above the Earth in the stratosphere, it helps protect life on the ground from solar radiation by scattering incoming ultraviolet rays from the sun... Read More

How is Ozone Formed?

Ozone does not come from a single source, but is formed in the air through a complex series of reactions involving light and chemical precursors. Although we cannot simply shut down a single emission source and stop ozone, we can limit the amount of precursor chemicals that produce ozone in the... Read More

Ozone In Houston

Although ozone levels have recently declined, Houston still has ample amounts of the ingredients necessary to form ozone in the atmosphere. With the petrochemical industry composing a substantial portion of Houston’s economic base and a population of around 6 million people, the Greater Houston...Read More.

EPA and Ozone

Although this site is mainly concerned with helping users to understand what happens when ozone is already present in the atmosphere, it is important to know that the Environmental Protection Agency (EPA) has regulated ozone and other air pollutants since the passage of the Clean Air Act in 1971....Read More

Ozone In the Body

Ozone enters the body when you breathe. As it travels through the mouth and nose’ ozone reacts with the linings of airways and starts chemical reactions which cause the tissues to break apart and then recombine with the excess oxygen. This recombination compromises the structure of the linings,...

How Do I Limit Exposure

When speaking about ozone prevention, it is important to recognize that there are ways through which ozone can be managed; the first, and most visible, is attempting to reduce the level of ozone in the atmosphere by controlling the amount of chemicals that we produce. Efforts in this area may...Read More

Ozone Exposure in Sensitive Groups

Although the health effects of ozone can vary greatly between individuals, the EPA recognizes that certain “sensitive” groups may be at greater risk to the adverse effects of ozone. These sensitive groups include children, who tend to be outdoors more, have developing immune and respiratory systems...Read More
