A region of the
stratosphere over Antarctica in which a marked decrease in the concentration of ozone has been
observed in the Antarctic spring in recent years. The origin of this phenomenon is
not yet established, but several theories based on both physical (transport related)
and chemical processes (involvement of the halocarbons and their products of
oxidation) have been suggested. The latter explanation appears to be in better accord with
recent findings.
