Abstract
For the first time accumulation level and distribution character of platinum in soil and in roots, stems, leaves, flowers, and seeds of Scutellaria baicalensis Georgi, Lamiaceae collected in natural habitats (south-western Primorye, Amur and Chita Oblasts) and introduced in Central Siberian Botanical Garden of SB RAS (Novosibirsk) have been studied using stripping voltammetry. In the habitats of S. baicalensis , the content of platinum in soil varied from 0.001 to 0.426 g/t. The content of platinum in different parts of the plants varied from 0.001 to 0.43 g/t. The bioaccumulation factor of platinum in S. baicalensis from different habitats varied from 0,01 to 6.1 g/t.
