Bromine cycle

Bromine cycles throughout the ocean, land, and between the stratosphere and troposphere layers of the atmosphere. The major sources are sea salts and the ocean, volcanos, biomass burning, polar regions, and salt deposits. The major sink of bromine is deposition. Image modified from

The bromine cycle is a biogeochemical cycle of bromine through the atmosphere, biosphere, and hydrosphere. Bromine has natural and anthropogenic sources, impacting each sphere as bromine is stored, released, or taken up. Ozone depletion and health hazards to humans, animals, and plants are effects of bromine throughout the environment.
