Abstract: A liquid chromatography and mass spectrometry method for determination of 11 environmental estrogens in food packaging materials was developed. The samples were dissolved by dichloromethane and precipitated by methanol. The filtrates were cleaned up through C18 SPE cartridge, and then separated with liquid chromatography, detected with mass spectrometry. Average recoveries between 81.4% and 111.11% and relative standard deviations between 3.9% and 9.7% were obtained for spiked samples. The detection limits of 11 environmental estrogens were between 0.0075 mg/kg and 0.32 mg/kg.

Key words: food packaging materials, environmental estrogens, phenols, SPE, LC-MS
