THE CONTENT OF HEAVY METALS OF THE COASTAL ZONE OF THE ESTERN ISSYK-KUL REGION
Atomic emission spectral method was used to determine the content of copper, lead, manganese in the organs of plants belonging to the Barberry, Oleaster, Lamiaceae, Compositae and Gramineae families, from cultivated plants – winter wheat (cereals), Hungarian sainfoin (perennial). Different accumulation of elements by different plant species and their organs is observed. The samples were salted by the author in the laboratory of biogeochemistry and radioecology of the Institute of Biology of the National Academy of Sciences of Kyrgyzstan in the calibrated muffle furnace Naberthem. The heavy metals content in samples was determined in the accredited laboratory оf the state Committee of industry, energy and subsoil use of the Kyrgyz Republiс. The content of elements in plants depends on the species, as well as significantly affect the soil-geochemical conditions, which manifested the ratio Hippophae rhamnoides L. Plants-accumulators and plants-indicators of the elements were identified. The calculation of the coefficient of biological absorption, characterizing the intensity of biogenic migration. Heavy metals by the average content in the ash of plants are arranged in descending order Mn > Cu > Pb. The maximum concentration of copper and lead in most plants is found in the leaves. Manganese is accumulated mainly in roots. Wheat grains are most protected from metals abundance. Flowers contain less than leaves and roots, but more than in stems. Hippophae rhamnoides L. is referred to indicators of copper, lead and manganese are hard to reach elements for all plants.
