The article describes pollution of soils with chlorine-containing substances and heavy metals, whichis one of the topical issues of the South Kazakhstan region. The distribution of heavy metals in the environment can be attributed to the mining industry, various chemical and metallurgical enterprises, theunsatisfactory use of fertilizers containing heavy metals in agriculture, automotive and thermal powerplants. The amount of heavy metals in the soil was determined by laboratory tests on the basis of statistical methods. Based on the results of this study, the amount of heavy metals in the soil was determined.Dosimetric observations in the regional engineering laboratory «Engineering and biochemical materials»named after M. Auezov showed that αβγ-reflections for natural fertilizer «Zhamb-70» were natural (background). In addition, adverse effects on the environment were not detected in the investigated models. Itwas identified of the residual content of organochlorine pesticides and heavy metals (copper, zinc, lead,cadmium) in plant growing and the environment of Southern Kazakhstan. The determination of active substances in samples of agricultural crops and soil was carried out by gas-liquid chromatography on aShimadzu device with an electron capture detector. The research did not reveal any harmful substancesthat affect the soil composition.Key words: Soil, heavy metals, the mechanical properties of the soil, soil acidity, pH indicator media.
