Abstract
For the first time, the platinum accumulation levels and distribution patterns in the soil and in roots, stems, leaves, flowers, and seeds of medicinal herb Scutellaria baicalensis Georgi, Lamiaceae (Baikal skullcap) have been researched using the stripping voltammetry method. The plants were collected both in their natural habitats (southwestern part of Primorskii krai, Amur oblast, and Chita oblast) and from the S. baicalensis population introduced in the Central Siberian Botanical Garden (CSBG), Siberian Branch, Russian Academy of Sciences (Novosibirsk). In the habitats of S. baicalensis, the content of platinum in soils varies from 0.001 to 0.426 g/t. The content of platinum in various parts of the plants varies from 0.001 to 0.43 g/t. The platinum bioaccumulation factor in S. baicalensis individuals collected in various habitats varies from 0.01 to 6.1 g/t.
