Marine environment ozone depletion

The chlorine chemistry is too slow for ozone depletion in the troposphere but bromine and, in particular, iodine provide - combining with heterogeneous chemistry (see below) - lead to ozone depletion in marine environments by the following catalytic cycles (Barrie and Platt 1995, Platt and Mortgaat 1999) A 5.398 < 5 10 cm molecule" s ... 

Whereas the role of halogens in the depletion of stratospheric ozone has been studied for several decades, the role of halogens in tropospheric O3 reactions in marine and polar environments has only been studied in the past 15 years. The competitive fate of halogen atoms (F, Cl, Br and I) is their reaction with ozone 5.388 = 1-2 10 cm molecule" s" .
