Excessive Copper Concentration in Voghji River Basin Caused Disastrous Condition
The excessive copper concentration caused disastrous condition in the Voghji River basin. Under the annual report by “Environmental Impact Monitoring Center” SNCO for 2012, the average annual concentration of copper in the samples taken from the Voghji River basin exceeded MPC up to 10.0 times, aluminum – up to 8.5 (except the section upwards Qajaran Town), selenium – up to 3.9 times and chromium – 3.0. Thus, the copper concentration in the river made up 100 mcg/l, aluminum – 340 mcg/l, selenium – 39 mcg/l and chromium - 150 mcg/l.
Under EcoLur’s Ecological Risk Model, such concentration of copper is disastrous for the Voghji River.
