EVALUATION OF BIFENTHRIN GENOTOXICITY ON CHANNA PUNCTATUS

Author(s): Renu Chaudhari and Kamal Kumar Saxena*

The frequency of chromosomal damage in Channa punctatus by using chromosomal aberration test when exposed to synthetic pyrethroid bifenthrin was investigated. The frequency was examined in metaphase spreads obtained from fishes exposed to different sublethal concentrations (0.016, 0.0347 and 0.0628 ppm) of bifenthrin. Control fishes were kept in tap water. Chromosomal preparations were made from kidney cells of Channa punctatus after 5, 10 and 15 days exposure. Different types of aberrations like chromosomal gap, sticky plates, chromatid separation and breaks were observed in the cells of fishes exposed to bifenthrin. These aberrations were found significantly higher as compared to that of control and were statistically significant at (p<0.05) level. These findings obviously indicated that bifenthrin caused genotoxicity in Channa punctatus.
