The concentrations of fluorine (F), sodium (Na), magnesium (Mg), aluminum (Al), potassium (K), phosphorus (P), calcium (Ca), iron (Fe), nickel (Ni), zinc (Zn) and iodine (I) in the hair of 142 hydrofluoric acid (HF) exposed workers and 273 control subjects were analyzed by wavelength dispersive X-ray fluorescence spectrometry. Postshift urine and serum specimens were also collected for the determination of fluoride. To determine whether external contamination influences hair analysis, the control hair samples were kept in the work environment for one week. With the exception of lower K and Fe values, the levels of F and other elements in the hair of HF workers were higher than in the control subjects. The concentrations of F in hair and in postshift urine were in good correlation (r = 0.65). In the hair of HF workers F and Ca, F and Mg, F and P, F and Al were well correlated with each other (r greater than 0.6). F concentration in the hair increased after the sample was retained, however, it decreased to the reference value after washing. The levels of Ca, Mg and other elements did not change during the experiment.
采用波长色散X射线荧光光谱法分析了142名氢氟酸（HF）暴露工人和273名对照者头发中氟（F）、钠（Na）、镁（Mg）、铝（Al）、钾（K）、磷（P）、钙（Ca）、铁（Fe）、镍（Ni）、锌（Zn）和碘（I）的浓度。还收集了工人下班后的尿液和血清样本以测定氟化物。为确定外部污染是否影响头发分析，将对照头发样本置于工作环境中一周。除K和Fe值较低外，HF工人头发中F和其他元素的含量高于对照者。头发中F的浓度与下班后尿液中的浓度具有良好的相关性（r = 0.65）。在HF工人的头发中，F与Ca、F与Mg、F与P、F与Al之间均具有良好的相关性（r大于0.6）。头发样本留存后F浓度升高，但清洗后降至参考值。实验期间Ca、Mg和其他元素的含量未发生变化。
