Ozone is a gas that is composed of three oxygen atoms (O3). It is created by the oxides in the air’s nitrogen reaction with volatile organic compounds (VOC). Normally we think of ozone being higher in the atmosphere, also known as “good” ozone. However, when the conditions are right, ozone can occur at ground level, which is known as “bad” ozone. Sunlight and hot weather cause “bad” ozone in harmful concentrations. Thus in the summertime, urban areas have to be concerned about the amount of “bad” ozone. Why do you think urban areas are more prone to having problems with “bad” ozone?
“Bad” ozone creates a variety of health problems in people. People who are repeatedly exposed to breathing contaminated air have an increased chance of suffering from respiratory problems. Children and older people are the most affected.
Ground level ozone also interferes with the ability of plants to produce and store food. It damages the leaves of trees and other plants, and contributes to a reduction in crop productivity, because the plants are more vulnerable to disease, pests, and harsh weather.
Carbon monoxide (CO) is also a threat to the air we breathe. CO is formed when the carbon in fuel is not burned properly. The largest factor of CO emissions is automobiles. Cars, trucks, and buses account for 56% of the Earth’s carbon monoxide emissions. CO is also formed naturally. Forest fires and other fuel combustion (such as having a fire in your fireplace) also cause carbon monoxide to be emitted into the air.

Carbon Monoxide is toxic to humans. Even healthy people can be affected by carbon monoxide. People who breathe high levels of CO can develop vision problems, redued ability to work or learn, or have difficulty performing complex tasks. People who have heart disease may cause chest pains or other more serious cardiovascular effects.
The problem with air pollution is that it looks to be increasing in toxicity rather than being solved or reduced. More and more people are driving automobiles or trucks. And the Earth’s growing population is requiring more electricity to be generated at power plants. Do some research on what the air quality is like near your house or school. The Environmental Protection Agency monitors air quality by using the Air Quality Index (AQI). Are you surprised at the findings?
