Ecological assessment of soil contamination of Aktobe city with heavy metals

Abstract

This article discusses the results of chemical analysis of mobile forms of chemical elements (Cu, Ni, Pb, Zn, Co, Cd, Mb, Cr, Fe) in the soils of Aktobe city. Soil samples from 7 test plots in the territory of Aktobe city are studied. The concentrations of chemical elements are determined, and the concentration coefficients and the total index of soil pollution with heavy metals (Zc ) are calculated. The calculation results show that the level of soil pollution with heavy metals in 4–8 micro-districts and the area “Aviagorodok” is within Zc = 19.4–22.2 (16 < Zc < 33 is an average, moderately dangerous level), while in other studied zones it shows Zc < 16, i.e. low pollution.
