Induction of micronuclei in the erythrocytes of common carp, Cyprinus carpio (L) by caustic soda factory effluent


Author(s): M Ponnuraj, AG Murugeasan and N Sukumaran

Abstract: Studies concerning genotoxicity of industrial effluents are important in modern days. The present study was aimed to analyze the effect of mercury containing caustic soda effluent in fish which have -attracted many as laboratory animals for this type of study. Unfortunately, Cyprinus carpio are not suitable for chromosomal breakage studies because they have a high diploid number of chromosome (2n=100) which are small without marked variation in size. Recently, attempts have been made to examine the erythrocytes in fish for the occurrence of micronuclei (MN).In effluent exposed fish, a set time-response analysis demonstrated gradual decrease in the MN with an increase in exposure time. In the present study, concentration-response analysis showed the peak effect with 20% effluent at 24 hrs sampling periods, but with 21% at three sampling periods such as 48, 72 and 96 hrs respectively. Interestingly after 96 hrs exposure, no value was significantly higher than the control.
