Ozone layer protective action

Because ozone selectively absorbs these deleterious wavelengths of solar radiation, it serves as an ultraviolet shield. As such, stratospheric ozone helps to protect humans and other organisms on Earth s surface from some of the harmful effects of exposure to this high-energy electromagnetic radiation, hi fact, without the protective action of the stratospheric ozone layer, it is likely that... 

In Figure 20.83, determination of susceptibility to pitting corrosion was shown. The best-known example of an international environmental protection agreement that results, as a side effect, in a rearrangement of production processes and a withdrawal of products, is the Montreal agreement for the protection of the ozone layer. The prohibition of the production and use of specific chlorofluo-rocarbons that, aside from their action on the stratospheric ozone layer, are also water endangering has required rearrangements of production (Umweltbundesamt 1989).
