Аннотация

The article presents the results of a study of heavy metals concentration(Pb, Cd, Zn, Cu, Mn, Co, Ni)
in the following samples of dominant plants: Alhagi pseudalhagi, Artemisia terrae-albae, Ceratocarpus
arenarius and soils collected in the Mangistau region in 3 points: № 1 point (Aktau, the farm «Bereke»),
number 2 point (Fort-Shevchenko, agriculture ‘ Asem-Almaz «) and number 3 (of Zhanaozen, the farm
«Nurken»). The determination of heavy metals was carried out by atomic absorption spectrometry. The
procedure for performing measurements of the mass fraction of petroleum products in soil samples was
carried out on a Fluorat-02 liquid analyzer. It was found, the studied plants in the studied points have
different accumulative abilities: Artemisia terrae-albae revealed the best accumulative ability to store
heavy metals when as Ceratocarpus arenarius differs in that, in comparison with other plants that grow
together with them under the same environmental conditions, they accumulate the least heavy metals.
In all areas studied the content of heavy metals in soil samples it is within the acceptable level. However,
there is a general pattern of a slight excess of the permissible level of concentration in the range of 1.09
– 1.72 to the maximum permissible concentrations (MPC) for metals such as zinc, cobalt, which may be
related features physiographic zones and geological factors.
Key words: Mangistau region, heavy metals, atomic absorption spectrometry, the dominant species,
