Polígono Río San Pedro s/n, Puerto Real 11510, Cádiz, Spain a r t i c l e i n f o a b s t r a c t Article history: For many decades water resources in Armenia have been affected by anthropogenic activity, therefore, Received 17 October 2016 a regular bioindication of genotoxic effects of the water bodies is desirable. The genotoxicity of water Received in revised form 19 February 2017 samples collected from different parts of Lake Sevan were assessed by means of Trad-SHM (stamen hair Accepted 28 March 2017 mutation) assay using Tradescantia (clone 02). Here we report a significant increase in the frequency of Available online 31 March 2017 somatic mutations and morphological changes in the Tradescantia inflorescences exposed to the water samples compared to the control. The somatic mutations (recessive mutation and white mutation events) Keywords: were mostly linked to the concentration of Al, Ni, As, Co and Pb in Artanish, Tsapatakh and Karchaghbyur, Water pollution Noradus, Martuni and Litchk, while morphological changes (non-surviving hairs) were related to Co level Tradescantia (clone 02) Genotoxicity in Tsapatakh and Karchaghbyur.
