ABSTRACT

In the present study, gas chromatography (GC) was standardized for simultaneous detection of selected organochlorine pesticide residues viz., o,p’-DDE, p,p’-DDE, o,p’-DDD, p,p’-DDD, p,p’-DDT, α-HCH, β-HCH, γ-HCH, δ-HCH, and α-endosulphan in whole chicken egg samples with electron capture detector (ECD). All the egg samples were extracted and cleaned-up as per AOAC method No 970.52 and the final elute was subjected to GC-ECD for detection and quantification of organochlorine residues. The recovery for different isomers ranged between 53.26% (α-HCH) and 104.39% (p,p’ DDE). The limit of detection and limit of quantitation for the analytes were found in the range of 0.008 to 0.012 ng/g and 0.025 to 0.036 ng/g, respectively. The system precision was found to be less than 2.295% for area and less than 0.006% for retention time.
