Abstract
Forty poultry meat samples from four large companies were analyzed for the presence of organochlorine pesticides.
Homogenized samples were mixed with silica sand and anhydrous sodium sulfate, and extracted with ethyl acetate followed by
n-hexane: MTBE. Clean up of samples were done by silica sulphuric acid and analyzed by GC-ECD, and confirmed by GCMS.
The limit of detection (LOD) and limit of quantification (LOQ) were 0.5, 0.5 and 0.7, and 2.5, 2.5 and 3.5 ng/g,
respectively. The calibration curves were linear and the correlation coefficients (r
2
) were 0.991, 0.992 and 0.997 for DDE,
DDD and DDT, respectively and the recoveries for them were 76%, 78% and 80%. DDT and its metabolites, DDE and DDD
were detected in 28 (70%), out of 40 samples and ranged 0.039-0.769 mg/kg.
