A study and multivariate statistical analysis of Fe, Co, Ti, V, Mn, Ba, Cu, Pb, Zn, Mo, Cr, Sr, Rb, and Zr concentrations in bottom sediments of the section of the Hrazdan River passing through Yerevan area was carried out at Center for Ecological-Noosphere Studies of National Academy of Sciences of RA.
"The findings of this research showed that the geochemical associations of Fe-Co-Ti-V-Mn-Zr and Sr-Ba-Rb elements in the bottom sediments of the section of the Hrazdan River passing through the Yerevan territory remained close to natural, whereas the Pb-Mo-Zn-Cr group was an association formed as a result of the anthropogenic impact," Gevorg Tepanosyan said, Head of Department of Environmental Geochemistry at Center for Ecological-Noosphere Studies of National Academy of Sciences of RA.
