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

The genotoxicity of ground water from four bore-holes of different depths (40-120m) in the Ararat valley (Armenia) used both for drinking and irrigation was investigated. The frequency of recessive somatic mutations was determined using the Tradescantia-stamen-hair-mutation (Trad-SHM) test. The Tradescantia clone 02 was used.
