Heavy metals accumulation by the vegetation of the territory of the East Kazakhstan

Abstract

The objective of this work was study and assessment of the main regularities of distribution of forms of finding of the heavy metals: Cu, Zn, Mn, Co, Pb, Cd, in the plants of the territory of the east Kazakhstan. It was found that the same species of a plant accumulates the different number of HM on different types of soils. The vibration amplitude of content of the researched elements in species of the plants growing on various types of soils makes 1.1 – 6.3 times. Varying of the HM content in botanical plant families is in a small range. Zinc is characterized by a basipetal distribution along the morphological organs of plants, for the copper and manganese the acropetal distribution is characteristic. The coefficient of biological absorption of all elements was higher in plants of the family Fabaceae Lindl.
