The identification of clastogenic impacts of water in Hrazdan river by studying the peripheral blood erythrocytes of lake frog (Pelophylax ridibundus)

Abstract

To identify the possible clastogenic effects of the water environment in Hrazdan River, a micronucleus test was used on erythrocytes of peripheral blood of the frogs living in its various sections. Data on the effect of pollution of the aquatic environment were also obtained by studying the morphological features of the nuclei of erythrocytes. According to the data obtained, a large number of erythrocytes with micronuclei, relatively high percentage of nuclei with protrusions, as well as vacuolated nuclei are found in frogs inhabiting in the sections of Hrazdan River that are characterized with a high degree of pollution (villages Darbnik and Geganist). A positive correlation was revealed between the data of the micronucleus test and the data obtained as a result of study of the morphology of the nuclei of erythrocytes. Thus, the data obtained makes it possible to draw a conclusion on possible clastogenic effect of the waters of Hrazdan River in the areas of the villages Darbnik and Geghanist.
