abstract
By the method of atomic absorption spectrometry, the trace element composition of venom Macrovipera lebetina obtusa, from different regions of Azerbaijan has been studied. Ions - Cr, Pb, Cd, Zn was revealed in venom of snake. The metal concentrations in the venom of snakes fluctuate within: Cr - (87.0± 0.049 - 103.1±2.793) mg / kg; Pb - (7.01±1.321 - 134,8±1.46) mg / kg; Cd - (1,6±0.177 - 24.2±0.985) mg/kg; Zn -(600.89±4.266 - 860.9 ± 0.129) mg/kg, respectively. γ –Radiospectrometric studies have shown that the venom samples contain radionuclides Ra ²²⁸ (0.08-0.174 mBq/g), Ra226 (0.35-2.48, mBq / g) K⁴⁰ (1.35-23.4 Bq/kg) and Cs¹³⁷ (MDA = 0.315. It was found that, in heterojunction "snake venom - p-InSe» viper venom be haves as a semiconductor p-type conductivity.
