The atmospheric degradation of 1-bromopropane and its degradation products are examined with respect to their ability to deplete stratospheric ozone. It is shown that the OH initiated oxidation of 1-bromopropane does not lead to long lived bromine containing species. Laboratory measurements of the UV absorption cross sections and photodissociation quantum yields of chloroacetone and bromoacetone are presented. The atmospheric photolysis lifetime of bromoacetone at mid-latitudes is determined to be on the order of hours.
