Synchrotron X-ray fluorescent analysis application in biogeochemical investigations in Yakutia

Large possibilities of synchrotron X-ray fluorescent analysis (SR-XRFA), along with the simple preparation of biological samples, allowed us to carry out valuable biogeochemical investigations in Yakutia during the years 2002–2008. New data on the accumulation of macroelements K, Ca, Fe, Mn, biophilic microelements Cu, Zn, Mo, chalcophilous Ni, Pb, Ag, As, Sb, rare lithophilous Rb, Sr, Zr, Y, Nb, scattered chalcophilous Ga, Ge, Se, Cd, Te, Tl in the tissues of larch (Larix cajanderi Mayr.), mosses and lichens (Cladina genus, Dicranum genus, Hylocomium) were obtained. A connection between the elemental composition of larch tissues and the composition of bed rocks was revealed; a comparison with the elemental composition of mosses and lichens was carried out.
