OBJECTIVE: To study the status of perfluorooctane sulfonate (PFOS), and Perfluorooctanoic acid (FOA) pollution in serum and umbilical blood among general people in Shenyang area. METHODS: Concentration of PFOS and PFOA in adult serum and umbilical blood samples was measured by means of liquid phase chromatography/mass spectrograph selective iron monitoring (PFOS: m/z = 499, PFOA: m/z = 413). RESULTS: It was showed that geometric mean of serum concentration of PFOS of male was 40.73microg/L and that of female was 45.46microg/L, PFOA is 11.53microg/L and 8.97microg/L. Geometric mean concentration of PFOS and PFOA in umbilical blood was 2.214microg/L and 0.264microg/L. There was no correlativity between concentration of PFOS, PFOA and age in adult serum and umbilical blood. CONCLUSION: It was suggested that there was PFOS contamination in common group in Shenyang. Also, fetus was exposed in PFOS and PFOA during its embryonic period. There were also PFOS and PFOA pollution in human umbilical blood samples.
