acute genotoxic effects of effluent water of thermo-power plant “kosova” in tradescantia pallida

the aim of this study was the evaluation of acute genotoxic effect of effluent water of thermo-power plant by means of tradescantia root tips micronucleus test (mn), mitotic index and cell aberrations.   tradescantia , was experimentally treated (for 24 h), with effluent water of thermo-power plant in different dilution ratios (negative control – distilled water; primary untreated effluent water and 1:1; 1:2; 1:3; 1:4; 1:5; 1:6 and 1:7 respectively). number of aberrant cells, and frequency of micronuclei (mn), in meristematic root tip cells of treated plants ( tradescantia ), were significantly increased (p<0.001; p<0.001 respectively), while the mitotic index in all treated plants was progressively decreased in comparison to the negative control. the results of present study indicate that tradescantia root-tip micronucleus assay with direct exposure of intact plants is an appropriate method which enables to detect genotoxic effects of effluent waters.
