Bioindication of water pollution of Lake Sevan freshwater ecosystem (Armenia) using model test-object

Abstract

The process of bioindication of genotoxic effects of complex mixtures on the water resources using plants test-objects is very appropriate and effective. Test-systems based on plant use have shown high sensitivity and are recommended for monitoring genotoxicity of xenobiotics in the air, water and soil (Grant, 1994; Ma, 1999; Aghajanyan et al., 2015). Among plants test-objects, the heterozygote clones for flower color (blue-dominant, pink-recessive) of Tradescantia (clones 02 and 4430) plays a special role. The Tradescantia stamen hair mutation (Trad-SHM) and Tradescantia-micronucleus (Trad-MCN) bioassays are the efficient and reliable biomonitoring test-systems for detecting the genotoxicity and clastogenic effects of environmental pollutants (
