极谱分析人员头发、指甲和尿中的汞含量及其评价

The Content of Mercury in Hair,Nail,and Urine of Polarographic Analyst and Its Evaluation

为查明汞在极谱分析人员体内吸收、积累与排泄情况，用无火焰原子荧光法测定了２１例极谱分析人员（检查组）和２２例非接触汞人员（对照组）头发、指甲和尿中的汞．结果表明，检查组头发、指甲和尿中汞含量均明显高于对照组（Ｐ＜０．００１）；性别之间无显著差异（Ｐ＞０．０５）；汞的积累与接触汞史有关，与年龄无关．发汞和指甲汞远比尿汞高，且含量稳定，因而头发和指甲的监测可作为血清和尿分析的补充手段，在职业病及环境医学方面甚至可代替尿汞监测。

Information regarding that mercury is absorbed,accumulated,and excreted by the bodiesof polarographic analysts is inverstigated, by means of flameless nodispersive atomic fluorescence spectrometry,the mercury contents in hair,nail.and urine of 21 polarographic analysts(test group)and 22 nonmercury-contacting persons(control group)are determined respectively' The findings indicate(1)the polarographic analysts have much more mercury in theirhair,nail.and urine as compared with the control group in each items(P<0. 001). (2) hereis no distinct difference in mercury content between male and feamle(P >0. 05).(3) the individual-contained mercury only depends on the duration of that the person contacts withmercury rather than on his age.and(4)the mercury content is much higher and more stablein hair and nail than in urine of man's body.Based on these findings,it can be concluded thatmonitoring the mercury found in hair and nail of people is a helpfully supplementary methodto the serum and urine analysis:furthermore.it can be uesed hopefully instead of the monitoring mercury of urine in enviromental medicine. and the prevention and cure of occupationaldisease.
