SOIL CONTANIMATION WITH HEAVY METALS IN ALMATY (CD, PB, ZN,CU)

Abstract

The work is devoted to the study of the content of heavy metals in soils at the crossroads of the main streets of Almaty. It was found that the content of mobile zinc in soil in the vicinity of the Ryskulov-Seifullin streets exceeded maximum of 50 %. In soil samples taken near Raiymbek -Seifullin and Abay-Seifullin, the content of this form of zinc corresponds to the MAC or has a value close to the MPC. The number of mobile forms of copper in soils taken near the Kazakh National University. al-Farabi is equal to MPC or is close to MPC. The concentration of lead in soil samples taken near Ryskulov-Seifullin and Raiymbek-Seifullin reached values close to MPC. At the same time, this figure at the intersection of Raiymbek-Seifullin streets was equal to the MPC or had a value close to it. MPC of gross zinc is 100 mg/kg, and in the area of Ryskulov-Seifullin streets its content in the soil was 290.0 mg/kg, which is 2 times higher than MPC. In soil samples taken near the streets of Raiymbek-Seifullin, this figure was 156.8 mg/kg, which exceeds the MPC by 56.8 mg/kg.the content of the gross form of copper in soils taken near Kazgugrad is MPC.
