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.

Abstract:The objective of this work was study and assessment of the main regularities of distribution of forms of finding of Zn, Pb in light chestnut soils of the territory of the island "Polkovnichii" (Semey, Kazakhstan) as a basis of assessment of influence of technogenic pollution and development for successful monitoring of a surrounding medium, protection of soils. It was found that average total of Pb content of 1.2 times, of Zn content -2.4 times lower than their clark contents in soils. The examined soils on the level of the average content of mobile forms of zinc are the medium soils by the presence of this element. Reliable direct correlative dependence on a humus and рН for acid soluble (extracting agent -2.5% of CH 3 COOH) form of lead is revealed. Reliable positive correlative dependence on values рН the forms of Zn strongly bound to organic matter of the soil is found. It was revealed that the migration of forms of finding of lead and zincum on a profile of the soil happens nonuniformly: accumulation of zinc is noted in the top horizons of the soil -humic A n and the humic accumulative horizon of A 1 . It was found that accumulation of lead happens in the illuvial horizon of B 1 of the investigated soils.
