Interpopulation differences in hemocyte DNA-comet parameters of snail Lymnaea stagnalis from regions with different environmental loads

Article

Abstract

Research on hemocytes of snail Lymnaea stagnalis from regions with different environmental loads has been carried out by comet assay. Significant interpopulation differences in hemocyte DNA-comet parameters and sensitivity of hemocyte genetic material to external damaging factors (heavy-metal Sr, in particular) have been revealed by means of software analysis of hemocyte DNA-comet images. Two snail populations are characterized by high genetic identity; therefore, the different proliferative activity in the hemocytes of snail Lymnaea stagnalis from different ecological zones revealed by comet assay may be considered as an indicator of the intensity of damaging effects and environmental quality.
