Mutagenicity of ground water (in the bore-holes) in Ararat Valley (Armenia) detected by Trad-SHM bioassay

Assessment of mutagenicity of water from Lake Sevan, Armenia with application of Tradescantia (clone 02)

“…The contents of all bottles from each site (totaling 3 L) were mixed together and 150 mL samples taken for testing. The assay has been described in detail by Pogosyan et al [15] and Aghajanyan et al [2]. In brief, young inflorescences of the plant were submerged in water samples (3 inflorescences per vessel) for 18 h and after a 7-day recovery period, the flower blossoms were examined.…”

“…They were shown to perform successfully in dose-response studies and as biodetectors of chemical mutagens [14,9,5,7,22]. Tradescantia was used in air monitoring programs [4], for evaluating toxicity of sewage sludge and liquid samples [10,15,2] and soil samples [1]. Trad-SHM test is a reliable and sensitive system for monitoring gaseous and liquid mutagens in the laboratory [12] and in situ [4].…”

“…Многолетними исследованиями нашей научной группы была показана возможность и перспективность использования индикаторных биотестов Трад-ВТН и Трад-МЯ в практике генетического мониторинга загрязнения окружающей воздушной, водной и почвенной сред, как вблизи источников техногенного загрязнения, так и в городских условиях экологической нестабильности (Pogosyan et al, 2002;Agadzhanyan et al, 2011).…”
