TL;DR: The estimate of BrO emission leads us to conclude that local ozone depletion and small ozone ‘holes’ may occur in the vicinity of active volcanoes, and that the amount of bromine emitted from volcanoes might be sufficiently large to play a role not only in the stratosphere, but also in tropospheric chemistry.

TL;DR: In this paper, the main effects of volcanic emissions on atmospheric chemistry are discussed, with a focus on sulphur and halogen compounds, and to a smaller extent on climate, mainly focusing on quiescent degassing, but the main effect of explosive eruptions on the troposphere and stratosphere are covered as well.

TL;DR: In this article, the authors measured the BMo and SO2 abundances as a function of the distance from the source by using ground-based scattered light Multiaxis Differential Optical Absorption Spectroscopy (MAX-DOAS) in the volcanic plumes of Mt. Etna.

TL;DR: In this paper, the first direct evidence of fast oxidation of halogen species in a volcanic plume, and lead to an explanation of how BrO is generated from magmatic HBr emissions.

TL;DR: The distribution of bromine monoxide (BrO) and sulphur dioxide (SO2) was measured by ground-based MAX DOAS (scattered light Multi Axis Differential Optical Absorption Spectroscopy) in the plume of five volcanoes:; Soufriere Hills Volcano on Montserrat in May 2002, Masaya volcano in Nicaragua in March 2003, Etna volcano on Sicily in September/October 2003, Stromboli volcano in Italy in September 2003, and Villarica in Chile in November 2004.
