To make further progress, we should start focusing on road transportation and commercial and residential emissions. They then used the GEOS-Chem atmospheric chemistry transport model to track where these emissions ended up, from season to season and year to year, based on wind patterns and a pollutant’s chemical reactions to the atmosphere.

Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant. Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface.
