Pages: 265-268


It is established that the coefficient of biological absorption of rare earth elements allows one to characterize them by the weak level of intake by the top mass of pastoral grass. The concentrations of lanthanum, neodymium and samarium in the top phytomass of a natural pasture of the cryolite zone in Transbaikalia is 2.3-4.5 times lower than in roots.
