- Pollution levels of perfluorochemicals in eggs purchased from the markets in Beijing had been investigated. The egg samples of chicken and duck were collected from the 59 stalls of 14 main eggs wholesale markets in Beijing, respectively. Systematic analyses were made for seventeen kinds of perfluorochemicals (11 perfluorinated carboxylates (PFCAs), 3 perfluorinated sulfonates (PFSAs), perfluorooctane sulfonamide (FOSA), 2-perfluorooctylethanoic acid (FOEA) and 2H-perfluoro-2-decenoic acid (FOUEA) by a high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The results showed that there was a certain perfluorochemical contamination in all egg samples. Nine kinds of perfluorochemicals were detected in chicken eggs, perfluorononanoic acid (PFNA), perfluoroheptanoic acid (PFHpA) and perfluorooctanoate acid (PFOA) are dominant, and their average concentrations were 0.105, 0.073 and 0.069 ng x g(-1), respectively. Ten kinds of perfluorochemicals were detected in the duck eggs, perfluorooctane
