The bromine cycle is similar to the chlorine cycle.
|
|
|
| q |
The natural source of bromine is Methyl Bromine (Ch3Br), which is a
|
|
|
|
byproduct of biological activity in the ocean. These
natural source reacts in
|
|
|
the troposphere.
|
|
|
| q |
The man-made source of bromine is two chemical
compounds: Halon-1211
|
|
|
(CF2ClBr) and Halon-1301 (CF3Br).
|
|
|
| q |
These two halons are used in
certain types of fire extinguishers.
|
|
|
| q |
Halons diffuse up to the stratosphere, where they are photolyzed
into
|
|
|
bromine atmos. They eventually rain out.
