They deduced that the "aerosol particles act as a base for multiphase reactions leading to ozone moodle thesis completion tool loss."9 Chlorine and bromine cooperates with stratospheric particles such as ice, nitrate, and sulfate to speed the reaction. The bromine and fluorine in these chemicals act as catalysts, reforming ozone (O3) molecules and monatomic oxygen into molecular oxygen (O2). Since the life of these molecules is around 100 years, even with the adoption of protocols put forward at Montreal and London which were further refined at Copenhagen to make them acceptable to all countries, the ozone layer is not likely to make a significant.
