Ozone, influence on humans and living creatures

Ozone (O3) is mainly found in two layers of our atmosphere

Stratospheric ozone plays a critical role for the biosphere because it largely absorbs the damaging ultraviolet radiation, allowing only a small part of the radiation to reach the Earth.

Absorbing ultraviolet radiation, ozone is a source of heath and is in this way actually responsible for the formation of the stratosphere itself (which is a layer where temperature rises with increasing height).

Difference between tropospheric and stratospheric ozoneOzone is essential to explain the temperature structure of the terrestrial atmosphere.

If unhindered by the filtering effect of the ozone, the full UV-B radiation would reach the Earth’s surface.

As suggested by many experiments on plants and animals and clinical research on humans, an increased exposure to UV-B radiation has its damaging effects.




Tropospheric ozone, on the contrary, is a so-called secondary pollutant, a photo oxidant which is formed by the interaction of solar radiation with primary polluting precursors.

Tropospheric ozone results from complex chemical reactions, in which nitrogens, volatile organic compounds, carbon monoxide, temperature and sunlight play a substantial role. Tropospheric ozone is a poisonous substance that harms humans, animals and plants.
