Abstract Egg yolk was spiked withp,p′-dicofol (p,p′-DCF) (0.1–2.0 μg/gm),p,p′-dichlorobenzophenone (p,p′-DCBP) (0.1–2.0 (μg/gm), and 1,1-bis(4-chlorophenyl)-2,2-dichloroethylene (p,p′- DDE) (0.05–1.0 μg/gm). The fortified egg yolk (2–5 g) was mixed with acetonitrile to extract non-fat organic materials. After removal of acetonitrile, the spiked chemicals were separated with a column chromatograph packed with acid alumina. Recovery efficiencies forp,p′-DCBP andp,p′-DDE were determined by gas chromatography, and forp,p′-dicofol by high performance liquid chromatography. The recovery efficiencies forp,p′-dicofol,p,p′-DCBP andp,p′-DDE were 77.2–93.8%, 84.1–101.1%, and 88.5–96.0%, respectively.
