ANNOTATION
The article presents the results of the study of bitter wormwood (BW) selected in the soil of the Bobojoh gafurov district of Sughd region. It was found that the content of Zn, MnO and Ni is higher in BW, and content of Pb, Cu, As, Cu, Sr, V and Co is higher in soil, that is, soil is more enriched with these elements. The contents of Fe2O3, Cr and TiO2 are the same in the composition of the samples. The increased contents of Pb, Cu, As, Cu, Sr, V and Co in the local soil indicates to possible anthropogenic impact. The content of copper, cobalt, lead, titanium and strontium is higher than their Clarke in the soil, and as for the rest of HMs, they was found. The biological absorption coefficient for BW for Zn (19.81), Ni (8.83), MnO (1.81), Cr (1.44) and Sr (1.12) is greater than unit (K> 1) which means their intensive transfer from soil to plants; as for other elements the latters demonstrated their deficiency are poorly captured. This fact indicates that BW can be used for rehabilitation of soils with high contents of Zn, Ni and Cr, since these elements are classified as dangerous ones according to hazard classification.
