Fractional composition of compounds of zinc and lead in light chestnut soils
AbstractThe 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 CH3COOH) 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 leadand zincum on a profile of the soil happens nonuniformly: accumulation of zinc is noted in the top horizons of the soil – humic An and the humic accumulative horizon of A1. It was found that accumulation of lead happens in the illuvial horizon of B1 of the investigated soils.
