Mercury stable isotopes
Web28 mei 2015 · Mercury, Isotopes Abstract Production of methylmercury (MeHg) in ocean waters and its bioaccumulation in marine organisms are critical processes controlling the … WebThe word isotope is derived from Ancient Greek: the prefix iso-means "same," while -tope (from the Greek word topos) means "place."The isotopes of a given element always contain the same number of protons and therefore occupy the same place on the periodic table. However, because isotopes contain different numbers of neutrons, each isotope has a …

Web25 aug. 2024 · The element mercury (Hg) can develop large mass-independent fractionation (MIF) (Δ 199 Hg) due to photo-chemical reactions at Earth's surface. This results in globally negative Δ 199 Hg for terrestrial sub-aerially-derived materials and positive Δ 199 Hg for sub-aqueously-derived marine sediments. By comparison, a HIMU … WebOur study reports the first data on mercury (Hg) isotope composition in marine European fish, for seven distinct populations of the European seabass, Dicentrarchus labrax. The use of δ²⠰²Hg and Π¹⠹⠹Hg values in SIBER enabled us to estimate Hg isotopic niches, successfully discriminating several populations.
