Abstract


A multiresidue method was developed and validated for simultaneous determination of 11 organochlorines, 8 synthetic pyrethroids and 14 organophosphorous pesticides in green gram and black gram grain samples using gas chromatography - electron capture detector and flame thermoionic detector (GC-ECD/FTD). The QuEChERS principle based methodology was adopted for extraction. Samples were extracted with acetonitrile and the co-extractives were removed using dispersive solid-phase extraction (dispersive-SPE) with primary secondary amine (PSA) after salting out with NaCl and MgSO 4 . Average recoveries for all the pesticides studied were between 71.70 and 113.31 % and relative standard deviation (RSD) ranged between 0.10 and 12.79 %. The present study indicates that the proposed method is useful in monitoring Organic Chlorine, Synthetic Pyrethroids and Organo Phosphorus insecticides in selected pulse grains.
