Influence Of Ecological Factors (Heavy Metals And Radiation) On Lizards Of Azerbaijan

摘要

Influence of ecological factors (heavy metals and radiation) on lizards of Azerbaijan has been revealed. Content and quantity of heavy metals in the samples of Sauria, plants, water tests, as well as in soil tests taken from the habitation place of the Sauria under study, has been determined by the roentgen florescent spectrophotometer method (XRF) - Innov -X firm. The activity of radionuclides in the samples was conducted at "Canberra" γ-spectrometer with a plenary HP Ge-detector. Natural radioactive elements in investigated samples have been revealed. These radio nuclides are isotopes ~(226)Ra and ~(228)Ra (together with disintegration products), entering into numbers of natural radio actives ~(238)U and ~(232)Th and isotopes of natural radioactive ~(40)K not entering into these numbers. Higher concentration of heavy metals and activity of ~(238)U , ~(235)U and ~(40)K isotopes has been defined in the organisms of Sauria. Presence of small activity of radio nuclides in investigated samples testifies to presence of influence of environment on an organism of lizards and possibly on their biodiversity. The data obtained by us testifies to accumulation of ecological pollutants in an organism of lizards, thus influencing a biodiversity and morphological changes of animals on preliminary our supervision. The data on accumulation of radio nuclides and heavy metals can serve in an organism of lizards as criterion of a condition of impurity of biosphere and can be applied in quality of bioindicators of environment.
