Abstract
Egg yolk was spiked with p,p'-dicofol (p,p'-DCF) (0.1-2.0 micrograms/gm), p,p'-dichlorobenzophenone (p,p'-DCBP) (0.1-2.0 micrograms/gm), and 1,1-bis(4-chlorophenyl)-2,2-dichloroethylene (p,p'-DDE) (0.05-1.0 micrograms/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 for p,p'-DCBP and p,p'-DDE were determined by gas chromatography, and for p,p'-dicofol by high performance liquid chromatography. The recovery efficiencies for p,p'-dicofol, p,p'-DCBP and p,p'-DDE were 77.2-93.8%, 84.1-101.1%, and 88.5-96.0%, respectively.Entities:
