Abstract
Developed multi residue method for 38 pesticides on GC-ECD Shimadzu 2010. Organochlorines, organo phosphates, synthetic pyrethroids mixtures of standards supplied by Ehrensortfer were prepared in (1:1) hexane:toluene. Eight different concentrations of standards i.e., 0.005, 0.01, 0.025, 0.050, 0.075, 0.1, 0.25 and 0.50 ppm were prepared and injected six replications into GC-ECD. Linearity curve was drawn for each pesticide and regression values were calculated. The regression values for organo-chlorines were found from 0.940 to 0.990 and % RSD values were in permissible range from 0.57 to 10.4. For organophosphates regression values were found from 0.992 to 0.998 range % RSD values were ranged from 0.66 to 14.02. For synthetic pyrethroids, regression values were ranged from 0.956 to 0.999 and % RSD values ranged from 1.1 to 8.9. For all the pesticides linearity curve with all the regression values ³ 0.940 and % RSD values in permissible range from 5.7 to 14.02.
