THE CONCENTRATION OF CHEMICAL ELEMENTS IN THE SHOOTS OF LEDUM PALUSTRE L., GROWING IN THE AREA OF BYSTRINSKY GOK (EASTERN TRANSBAIKALIA)

The purpose of the research is to establish the concentration and absorption level of a number of chemical elements in the shoots of Ledum palustre L. in an area with geochemical anomalies of natural and anthropogenic origin. For this purpose, samples of soil and shoots of L. palustre were taken in natural communities. The total content of chemical elements in the soil and the concentration of elements in the plant were determined by inductively coupled plasma mass spectrometry (ICP-MS). The concentration of chemical elements in L. palustre has been established.: K> Ca> P> Mg> Mn> Fe> Ba> Al> Na> Zn> Ag> Sr> B> Cu> Ti> Rb> Cr> Ni> As> Ce= Pb= V> La= Mo> Co= Ga= Li= Sb= W= Y= Zr> Cs> Pr= Sn> Cd= Sc= Se= Th= Tl> Be= Hg= Nb= Ta= Te= U> Ge> Bi; intensity range of biological absorption of elements: Ag> Se> Te> P> Tl> Nb> Mn> K> B> Ca> Cu> Zn> Ba> Bi> Cd> Mo> Mg> Rb> W> Sr> Hg> Cr> Ni> As> Ta> Sb> Co> Th> Fe> Cs> Sn> Na> Pb> Be> Ce> La> Li> Pr> Ga= Y> U= V> Ge= Ti= Zr> Al> Sc. A strong correlation has been established between the concentrations of Ag, Ni, Sr and Rb in L. palustre and the gross content of elements in the soil. Features of the elemental composition of L. palustre in the studied area was an abnormally high concentration of Ag, Se and As. The study in the Trans-Baikal Territory was conducted for the first time, it complements the known data on the chemical composition of L. palustre in Russia, and is of practical importance for pharmaceutical production.
