Hyderabad, 34, A.P., India 1 Four different concentrations of quinalphos and methyl parathion were tested on human peripheral lymphocytes over different time periods, for the analysis of chromosomal aberrations and sister chromatid exchanges (SCEs). 2 A significant increase in chromosomal aberrations was observed when cells were treated with quinalphos for 48 and 72 h and a significant increase in SCEs was observed at all the concentrations and over all the time periods. 3 Methyl-parathion did not induce chromosomal aberrations but it did induce SCEs significantly over all time periods.
