MORPHOLOGICAL CHANGES AND GENOTOXICITY IN CIRRHINUS MRIGALA (HAMILTON-BUCHANAN) EXPOSED TO DYEING INDUSTRY EFFLUENT
Gurinder Kaur Walia, Rohit Kalotra
Abstract :
<p>&nbsp;The present study deals with the acute toxicity of dyeing industrial effluent on a freshwater fish, Cirrhinus mrigala. 96h LC50 value came out to be 52.48%. Two sublethal concentrations viz., 26.24% and 6.56% were selected to study morphological changes and chromosomal aberrations after 24h, 48h, 72h, 96h and 120h. The physicochemical analysis of effluent indicated that it contains high amount of heavy metals which make it toxic and responsible for all these changes. The results depicted that higher concentration and exposure period caused severe damage in fishes and they cannot survive in the water containing high concentration of dyeing industry effluent. It is recommended that dyeing industry effluent should be treated before being discharged into river to maintain healthy aquatic ecosystem.</p>
