LEAD AND BISMUTH IN THE WORMWOOD ARTEMISIA GMELINI IN THE TAILING POND SHERLOVOGORSK MINE (SOUTH-EASTERN TRANSBAIKALIE)
The results of the comparative analysis of the contents of lead and bismuth in the bodies of Gmelini wormwood (Artemisia gmelinii), growing on the tailings of Sherlovaya former mining complex are given. It was determined that their content in soils and teсhno-soils significantly exceed the Clarks and Maximum permissible concentration (MPC). Soils background portion average content is (mg / kg) Pb 19,4 (10 to 30), Bi 9,86 (0,1 to 19,6), in techno-soils tailings - Pb 1056 (from 627 to 1700), Bi 10,67 (0,3 to 30,6 ). The content of lead and bismuth in wormwood of Gmelin is significantly lower than in soils and tech-nozem. The contents of lead and bismuth in wormwood Gmelini is significantly lower than in soils and teсhno-soils. The functional relationship between the content of these elements and techno-soils, soils and plants growing on them is not revealed. Accumulation of lead and bismuth in the bodies of wormwood differs significantly. The highest concentrations are found in the roots and leaves, much smaller in the stems and the minimum - in the flowers. In Gmelini wormwood organs (roots, stems, leaves, flowers) average bismuth content, respectively, is in the range (mg / kg) 3,15 ^ 0,16 ^ 0,53 ^ 0,12 in the scope of <0,01-3,15. The average values of the lead content of the same organs are, respectively (mg / kg): 33,24 ^ 11,44 ^ 30,30 ^ 10,56 in the scope <0,20-33,24. The contents of lead and bismuth in bodies of Artemisia gmelinii significantly exceed MPC dark for the plants at all areas
