Extraordinary pollution with copper, manganese and zinc has been observed in the section of the Voghji River downwards Kapan Town, which lead to ecological disastrous condition. Under the annual report by “Environmental Impact Monitoring Center” SNCO for 2012, the average annual concentration of copper in the section of the Voghji River downwards Kapan Town exceeded the MPC 119.6 times, manganese – 19.2, zinc – 11.4, nitrite ion – 3.0, ammonium ion – 2.3 and vanadium – 2.2.
Thus, the concentration of copper in the Voghji River made up 1196 μg, zinc – 570, manganese – 960, vanadium – 22, nitrite ion – 0.03 and ammonium ion – 0.46 mgN/l.
Under EcoLur’s Ecological Risk Model, the disastrous condition in the Voghji River downwards Kapan Town was caused by the excessive concentration of copper, zinc and manganese.
