The work is dedicated to the establishment of an ecological condition of the pastures in central mountainous part of Kakheti region located in Eastern Georgia. Namely, studies have been carried out on grass at its various phenological stages from pastures, located near the villages of Akhmeta, Sagarejo and Gurjaani municipalities. Studies of heavy metals content (copper, lead, cadmium and zinc) in grass have been performed through differential-pulse polarographic method. Based on the results obtained, it has been established that the quantitative concentration of heavy metals in grass collected in the above-mentioned municipalities is fully in line with international standards and does not exceed permissible limits thus clearly indicating to soil and overall ecological purity of the region, in general.
