Investigation on the genotoxicity of mercuric chloride to freshwater Clarias gariepinus.

摘要: Received: Revised: Accepted: June 10, 2013 September 11, 15, The cytogenetic effect of heavy metal was studied in Clarias gariepinus using the micronucleus test, chromosomal aberrations and sister chromatid exchange. fish were kept separately treated with four different concentrations mercuric chloride for a period 7 days. For test blood samples obtained from caudal vein. mean micronuclei frequencies recorded as 0.20, 0.25, 0.50, 0.65 0.79 controls 1.0, 2.0, 4.0 6.0 ppm groups chloride, respectively. Kidney tissues used vivo chromosome preparation. cells 0.21, 0.32, 0.49, 0.70 0.97 control 1, 3, 5 Similarly, exchange 0.10, 0.28, 0.47, 0.58 0.64 findings present experiment suggest that HgCl2 caused genotoxic effects fish. ©2013 PVJ.
