WebCredit: NASA. An ozone molecule consists of three oxygen atoms (its chemical symbol is O 3 ), and its maximum concentration in the stratosphere is a result of ultraviolet radiation's interactions with oxygen gas (O 2 -- the gas that humans need to breathe). When oxygen gas absorbs ultraviolet radiation, the oxygen atoms split. WebOzone-depleting substances ( ODS) generally contain chlorine, fluorine, bromine, carbon, and hydrogen in varying proportions and are often described by the general term halocarbons.
