Dangers of Ozone

Ozone is a dangerous pollutant. Hear what prominent voices have to say.

Breathing ozone can trigger a variety of health problems including death, chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. . . and may permanently scar lung tissue. . . Air pollution may have its largest impact on public health through its effect on the human embryo. Exposure of pregnant women to ozone at levels well below NAAQS results in intrauterine growth retardation including smaller head size, increased rates of spontaneous abortions, premature births and low birth weight syndrome.

Ozone generators that are sold as air cleaners intentionally produce the gas ozone. Often the vendors of ozone generators make statements and distribute material that lead the public to believe that these devices are always safe and effective in controlling indoor air pollution. For almost a century, health professionals have refuted these claims…. Some vendors suggest that these devices have been approved by the federal government for use in occupied spaces. To the contrary, no agency of the federal government has approved these devices for use in occupied spaces.

News about ozone can be confusing. Some days you hear that ozone levels are too high and other days that we need to prevent ozone depletion. Basically, the ozone layer found high in the upper atmosphere (the stratosphere) is beneficial because it shields us from much of the sun’s ultraviolet radiation. However, ozone pollution at ground level where we can breathe it . . . . causes serious health problems.

Short-term exposures to ozone have been associated with an increase in mortality as well as cardiovascular and respiratory-related hospitalizations. Ozone exposure can result in lung and throat irritation, lung inflammation, wheezing, and difficulty breathing. Exposure to ozone also exacerbates bronchitis, emphysema, and asthma.

Ozone (O3) is an extremely reactive gas molecule composed of three oxygen atoms. It is the primary ingredient of smog air pollution and is very harmful to breathe. Ozone attacks lung tissue by reacting chemically with it.
