In The Troposphere Ozone is a blue and highly reactive gas. Elevated altitudes are formed due to photochemical reactions. Its concentration varies with height. It is very oxidizing and therefore toxic to humans. May be primary or secondary contaminant. Ozone is a molecule made up of three oxygen atoms. In The Stratosphere It is a bluish-colored gas Ozone is a molecule made up of three atoms of oxygen. It forms and decomposes in the stratosphere from oxygen by the action of ultraviolet rays In the troposphere it is vital to life because it protects us from ultraviolet radiation emitted by the sun.

It is a dense protective layer of the atmosphere that allows to preserve life on the planet. It is composed of ozone that is located at 20-40km approx. on the surface of the Earth, and its concentration varies with height.

Charact eristics Ozone Layer Hole In the mid-1980s, ozone depletion was discovered above the Antarctic. Ozone depletion is caused by halocarbons. Nitrogen oxides can also make ozone disappear. Ultraviolet Radiation Set of radiations of the electromagnetic spectrum with wavelengths shorter than visible radiation (light), from 400 to 150 nm. Three bands of UV radiation are usually differentiated: UV-A, UV-B and UV-C.

How to prevent the disappearance of the ozone layer? Use only environmentally-friendly sprays and sprays. Do not use synthetic foams containing CFCs. The rules established in the Montreal protocol must be complied with by the countries that signed the agreement (halving the production of CFCs)
