Dioxygen species ozone

In the stratosphere, the region of the atmosphere from 10 up to 50 km, ozone is synthesized from dioxygen in a complex cycle of reactions. Thanks to its strong absorption of ultraviolet radiation in the range between 232 and 290 nm, ozone provides a protective shield for the plant and animal life on the earth s surface. Because no other atmospheric species can absorb the intense radiation in this range, the ozone layer is absolutely critical to the earth s inhabitants and has been the focus of numerous investigations. A major concern is the possible depletion of the ozone layer by nitrogen oxides from automobile exhausts and by Freons from aerosal sprays. [Pg.215]
