What is the Ozone Layer?
According to the EPA, the ozone layer protects life on Earth from the sun's harmful rays. What we know as the "ozone layer" is located in the stratosphere. The ozone resides an estimated 9 to 18 miles above the Earth's surface. While records have indicated that the ozone layer has been slowly depleting since the 1970s, ozone generators do not contribute to this loss.
Ozone Generators and the Ozone Layer
Ozone from a swimming pool ozone system will not add anything to the atmosphere or the ozone layer. When injected into the water properly, no ozone escapes into the atmosphere. Even if it does get into our atmosphere, it is like a drop in the ocean. Also, the ozone would have to be transported 9 to 18 miles up. The ozone results almost entirely from oxygen (O2) splitting apart into two atoms of oxygen (O2) by solar ultraviolet radiation (the sun’s UV rays) and then combining with molecular oxygen (O2) to form ozone (O3). Atmospheric ozone plays a critical role for the Earth by absorbing the ultraviolet radiation from the sun with a wavelength of between 240 and 320 nanometers (nm), which would otherwise be transmitted to the Earth’s surface. This radiation is responsible for sunburn to human skin. In addition, the incidence of skin cancer has been statistically correlated with UV light intensities of 290 to 320 nm.
