TL;DR: In the polar regions, unique photochemistry converts inert halide salt ions (e.g. Br−) into reactive halogen species that deplete ozone in the boundary layer to near zero levels as discussed by the authors.
Journal ArticleDOI
Dynamic oxidation of gaseous mercury in the Arctic troposphere at polar sunrise.
Steve E. Lindberg,Steve Brooks,Che-Jen Lin,Karen J. Scott,Matthew S. Landis,Robert K. Stevens,Michael Evan Goodsite,Andreas Richter +7 more
TL;DR: Data from Barrow, AK, at 71 degrees N show that rapid, photochemically driven oxidation of boundary-layer Hg0 after polar sunrise creates a rapidly depositing species of oxidized gaseous mercury in the remote Arctic troposphere at concentrations in excess of 900 pg m(-3).
Journal ArticleDOI
A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow

TL;DR: A review of the current understanding of AMDEs from field, laboratory and modeling work, how Hg cycles around the environment after AMDE, gaps in our current knowledge and the future impacts that AMDE may have on polar environments is presented in this article.
Journal ArticleDOI
A theoretical study of the oxidation of Hg0 to HgBr2 in the troposphere.
TL;DR: In this paper, the Rice-Ramsberger-Kassel-Marcus (RRKM) theory, together with ab initio quantum calculations where required, are used to estimate the following: recombination rate coefficients of Hg with Br, I, and O; the thermal dissociation rate coefficient of hgBr; and the recombination coefficient of O2.
Journal Article
A Theoretical Study of the Oxidation of Hg 0 to HgBrs in the Troposphere
TL;DR: A mechanism based on the initial recombination of Hg with Br, followed by the addition of a second radical in competition with thermal dissociation of HGBr, is able to account for the observed rate of H g0 removal, both in Arctic depletion events and at lower latitudes.
