Vanadium Causing Critical Condition of Lake Sevan
EcoLur
The cause of Lake Sevan critical condition is vanadium. Under the annual report by “Environmental Impact Monitoring Center” SNCO for 2012, the average annual concentration of vanadium in the samples taken from Lake Sevan exceeded MPC by 6.4 times, selenium – 2.6, copper – 2.1 and magnesium – 1.2. Thus the concentration of vanadium in the lake made up 64 μg/l, selenium 26, copper 21 and magnesium - 60 μg/l. Under EcoLur’s Ecological Risk Model, such concentration of vanadium only out of the elements mentioned caused critical condition for Lake Sevan.
