Abstract :

An aqueous-phase chemical mechanism has been proposed for the natural production of the active, inorganic bromine that breaks down the surface ozone over the Arctic every spring. The mechanism changes the nonradical bromine species HBr, HOBr and BrNO3 into the ozone-destroying bromine radicals Br and BrO. The presence of high levels of sulphuric acid aerosols known to coincide with ozone depletion would enhance the ability of this mechanism to increase bromine concentrations.
