Treasure of the Past: II: The Atomic Weight of Bromine
This paper from the Bulletin of the Bureau of Standards , Vol. 9, No. 1, 1913, pp. 131–150, is reprinted to commemorate the NIST Centennial on March 3, 2001. Ten papers have been selected from the Journal and its predecessors for this purpose, one from each decade of NIST’s existence. They appear in 10 of the 12 issues of the Journal published in 2000 and 2001, starting with the March–April 200...
متن کاملGlobal lifetime of elemental mercury against oxidation by atomic bromine in the free troposphere
[1] We calculate the global mean atmospheric lifetime of elemental mercury (Hg) against oxidation by atomic bromine (Br) in the troposphere by combining recent kinetic data for the Hg-Br system with modeled global concentrations of tropospheric Br. We obtain a lifetime of 0.5–1.7 years based on the range of kinetic data, implying that oxidation of Hg by Br is a major, and possibly dominant, glo...
متن کاملThe chemistry of atmospheric bromine
Bromine may act as a catalyst for recombination of ozone and could be more efficient than either nitric oxide or chlorine. The lower atmosphere contains small concentrations of gaseous bromine produced in part by marine activity, in part by volatilization of particulate material released during the combustion of leaded gasoline, with an additional contribution due to the use of methyl bromide a...
متن کاملOxidation of Aldoses With Bromine
Rates of oxidation of aldoses with bromine have bee n reappraised and inte rpreted in th e light of present concepts of conformation and reaction mechanism. It is suggested that differences in t he rates of ox idation of the a and /3 anomers are largely determin ed by differences in the free energy req uired by the reactants for passing from the ground state to the com plex in the transition st...
متن کاملBromine Toxicological Overview
The major route of exposure is by inhalation. Acute inhalation exposure to bromine vapour may cause upper respiratory effects, cough, headache, CNS effects and lacrimation. Acute oral exposure to bromine results in central nervous system effects. Deep partial skin loss and skin discolouration have been reported following acute dermal exposure to bromine. Ocular exposure to bromine cau...
