Acute Genotoxic Effects of Effluent Water of Thermo-Power Plant “Kosova” In Tradescantia Pallida

Abstract

The aim of this study was the evaluation of acute genotoxic effect of effluent water of thermopower 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.
