We have studied the features of heavy metal accumulation and the hygienic assessment of medicinal plants Sanguisorba officinalis L. growing on the Kedrovskii coal mine waste dump. We have revealed that embryonic soils of the waste dump contains low level of biologically active trace elements - Cu and Zn - below the sufficient soils supply according to Krupskoj - Alexandrova. The comparison of the heavy metal accumulation in the embryonic soils on the waste dump and the hygienic regulations have not revealed the over limits of the maximum permissible concentration (the approximate permissible concentration).We have established that medicinal plants Sanguisorba officinalis L. quantitatively contain biophilia metals (Fe, Mn, Zn, Cu) mostly, what is more, the burnet roots accumulate them more than the grass. The maximum biological absorption (Bx) has revealed that the burnet roots and the grass absorb Cu and Zn mostly.The minimum Bx rate has been discovered for metals transition from roots to grass. The analysis of heavy metal transition coefficient (Ct) has showed the highest degree of Pb, Cd and Zn translocation from the burnet roots to the grass. The minimum degree of heavy metals transition from the roots to the grass has been marked for Cu. The hygienic evaluation of medicinal plants Sanguisorba officinalis L. has showed the absence of heavy metal maximum permissible concentration and ranges within the regional background.
