Ecotoxicant content – heavy metals and radionuclides in embryonic soils and herbal medicinal products of Sanguisorba officinalis L. of the rose family (Rosaceae) in the circumstance of technogenicallydisturbed lands was analyzed, in example of the rock waste disposal areaof the Kedrovsky coal pit in Kemerovo region. It was experimentally proved that the embryonic soils of the coal dump is characterized by largeelemental variation. Analysis revealed that the raw materials of Sanguisorba officinalis L. more accumulates such metals as Fe(61, 95mg/kg), Mn (33, 46 mg/kg), Zn (17, 53 mg/kg) and Cu (12, 35mg/kg), which are related to biophilic metals. Technogenical group ofelements – Pb, Cd, Cr, Ni, Co, are with in 0,04 … 1,52 mg/kg. It was alsoexperimentally proved that the main share in overall radioactivity ofembryonic soils and rhizome and roots of greaterburnet falls to naturalradionuclides, especially K-40. The share of Cs-137 and Sr-90 are about7% in embryonic soils and 85 in rhizome and roots of burnet. Ecological hygienic assessment of Sanguisorba officinalis L. herbal medicinal products has shown the MPC no-exceedance of heavy metals and radionuclides, provided for the plant based BAA.
