为观察过量摄氟大鼠毛样中无机元素代谢变化，两组Ｗｉｓｔａｒ大鼠分别饮５０ｍｇ／Ｌ氟水和含氟量为０．３５ｍｇ／Ｌ的自来水，实验２４周处死。使用电感耦合等离子体发射光谱仪对比测定１２种元素含量。结果显示，过量摄氟大鼠毛中Ｋ、Ｎａ、Ｃｒ含量明显高于对照组，而Ｓｒ含量显著低于对照组，表明高氟可造成无机元素代谢紊乱 In order to observe the changes of inorganic elements metabolism in rats exposed to excessive fluoride exposure, Wistar rats in both groups were treated with 50 mg / L fluoride water and 0.35 mg / L fluoride water respectively, and were sacrificed 24 weeks after the experiment. The contents of 12 elements were determined by inductively coupled plasma atomic emission spectrometry. The results showed that the contents of K, Na and Cr in the hair of rats with excessive fluoride exposure were significantly higher than those of the control group, while the content of Sr was significantly lower than that of the control group, indicating that high fluorine could cause the metabolic disorder of inorganic elements
