The photochemical separation of mercury isotopes
Journal de Chimie Physique, 1963 Recent developments in the field of mono-isotopic mercury photosensitization are presented and discussed. By the use of a spacially- intermittent rotating sector, optimum mercury isotope enrichments are obtained in the reaction of hydrogen chloride, and the alkyl chlorides, with mercury isotopes, photo-excited in natural mercury vapor.

Application of mercury isotopes and their production
Journal of Radioanalytical and Nuclear Chemistry Articles, 1996 Mercury isotopes are now broadly applied in various fields of science and technology. They are used in medicine, nuclear physics investigations, RF standards, nuclear gyroscopes, mercury analysing devices etc. One of the most promising applications is the use of weakly enriched (up to 3%) isotope196Hg in fluorescent lamps for enhancing their light ...

Fractionation of Mercury Stable Isotopes in Lichens
SSRN Electronic Journal, 2022Bio-monitoring of mercury (Hg) in air using transplanted and in-situ lichens was conducted at three locations in Slovenia: (I) the town of Idrija in the area of the former Hg mine, where Hg contamination is well known; (II) Anhovo, a settlement with a cement production plant, which is a source of Hg contamination, and (III) Pokljuka, a part of a ...

Modeling Mercury Isotopic Fractionation in the Atmosphere
SSRN Electronic Journal, 2021Mercury (Hg) stable isotope analysis has become a powerful tool to identify Hg sources and to understand its biogeochemical processes. However, it is challenging to link the observed Hg isotope fractionation to its global cycling. Here, we integrate source Hg isotope signatures and process-based Hg isotope fractionation into a three-dimensional isotope

Nature, 1922
IT appeared to be so definitely one of the fundamental assumptions of physics that pure mercury has a constant density under given physical conditions that when Bronsted and Hevesy announced that they had separated it into fractions of different density (see NATURE, September 30, 1920, p.

Mercury isotopes in a forested ecosystem: Implications for air‐surface exchange dynamics and the global mercury cycle [PDF]
Global Biogeochemical Cycles, 2013 Forests mediate the biogeochemical cycling of mercury (Hg) between the atmosphere and terrestrial ecosystems; however, there remain many gaps in our understanding of these processes.
