the observed tropospheric background of reactive halogens, and how they might
change the atmospheric methane and mercury burden.
The abundance of (reactive) halogen species gives hints on processes
occurring in the Earth ' s interior, in particular on magma composition and on
degassing processes. For instance, we have known for half a century that
halogen/sulfur ratios measured in fumaroles indicate changes in volcanic activ-
ity (e.g. Cl/S: Noguchi and Kamiya, 1963 ). Recent observations suggest that
BrO/SO 2 ratios might be an indicator for magma composition changes and/or
magma pathway changes inside volcanoes

we have only just begun to
decipher these messages.
