Highlights C and N stable isotopes were measured in four compartments of Lake Titicaca. Anthropogenic discharge affects baseline C and N isotope signatures. C recycling from soil, anthropogenic and lacustrine
Abstract Antimony (Sb) is an emerging priority pollutant in the environment and a potentially carcinogenicelement. The general objective of this thesis is to contribute to exploring the potential of stableisotopes
Highlights Soils are locally affected by extreme Pb and moderate Sb contamination. Anthropogenic soil contamination is restricted to the surface horizons. Antimony isotopes allowed to discriminate Sb from mining vs
Highlights Experimental study of Sb isotope fractionation during its sorption on iron minerals. Light isotope of Sb was preferentially adsorbed on schwertmannite and ferrihydrite. Equilibrium fractionation factor (Δ123Sbsolid-solution) between −0.36
Highlights Antimony isotope fractionation during oxidation documented for the first time. Biotic and chemical oxidation fractionated Sb isotopes in opposite direction. Multi-step reactions underlie the fractionation process. Abstract Oxidation of
Highlights First estimation of equilibrium Sb isotope fractionation factors among Sb minerals. PBEsol pseudopotential best reproduces Sb mineral lattices and Raman frequencies. Factors affecting Sb isotope fractionation: Sb oxidation >
Abstract Antimony isotopes have been recently used as geochemical tracers for archeological or environmental purposes. The purification of antimony in samples with a low Sb concentration and a complex matrix
