Perfluorinated compounds (PFCs) have potential health risk to human. In this paper, human serum samples collected from Jiading District, Shanghai aged from 23 to 87 years old (12 male and 33 female) were analyzed for 17 perfluorinated compounds (PFCs). A novel method for the elimination of background contamination of perfluorooctanoic acid (PFOA) generated from instrument by the modification of high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) has also been developed and validated. The limit of detection (LOD) for all monitored PFCs range from 0.02 to 0.18 ng mL(-1). The limit of quantitation (LOQ) for PFOS and PFOA was 2.23 and 1.60 ng mL(-1), respectively, and for other PFCs it ranged from 0.04 to 0.88 ng mL(-1). Of the 17 PFCs analyzed in Shanghai serum, eleven were found. The dominating PFCs in all samples were perfluorooctanesulfonate (PFOS) and PFOA with a fraction of 49.5%, 34.2%, respectively. The median total concentration of each serum samples was 53.43 ng mL(-1) with a range from
