CONCENTRATION OF HEAVY METALS IN THE SOIL AND PLANTS OF AWNLESS BROME (BROMOPSIS INERMIS (LEYS). HOLUB.) IN AGROCENOSES OF THE ALTAI TERRITORY AND KEMEROVO REGION
The authors explored concentration of cadmium, lead, cuprum, nickel and zinc in the soil and awnless brome at livestock farms of Kemerovo region and Altai Territory. The authors explored total concentration of microelements by means of atomic emission spectrometry with arc argon two-spool plasmotron. The researchers found out that concentration of heavy metals in the soil doesn't exceed the hygiene standards and rates and it is typical for the south of western Siberia. Awnless brome consumes intensively cadmium, cuprum and zinc whereas concentration of all elements in Bromopsis inermis doesn't exceed the hygiene standards as well. The paper outlines that zinc concentration in awnless brome is rather lower than biochemical standard. This speaks about possible insufficient mineral concentration in the feeds.
