【摘要】 目的　了解我国一般人群体内的全氟辛烷磺酰基化合物 (PFOS)负荷水平。方法　采用液相色谱 /质谱仪联机选择性监测离子法 (m/z =499) ,测定被调查者血清中PFOS浓度。结果　男女血清中PFOS浓度几何均数分别为 40 73和 45 46μg/L ,血清PFOS浓度与年龄无关。 结论　我国一般人群体内也存在PFOS污染物 ,而且血清PFOS浓度高于美国人和日本人水平更多还原

【Abstract】 Objective To make clear the current level of PFOS in gene ral populaiton in our country.Methods To measure the plasma concentration of PFOS of th e investigated by means of liquid phase chromatography/mass spectrograph selecti ve iron monitoring(m/z=499).Results Geometric mean of serum concentration of PFOS of males is 40 73?μg/L and that of female is 45.46?μg/L,there is no correlativ ity between serum concentration of PFOS and age.Conclusion There exists PFOS contamination in common grou p in China and the level of serum concentration of PFOS is higher than that of A merican and Japanese.更多还原
