近年来,氟的职业性接触不断增加,迫切要求加强对这些工人的健康管理,并研究进行健康管理的特异指标,以作为积极的预防手段。作者从这点着眼,进行尿、血清氟含量的测定。为了阐明该项测定的意义,在了解非接触氟的一般工人尿、血清氟含量情况和接触容许浓度与较低浓度的氟化氢而引起的尿、血清氟含量变化的同时,并观察了样品采集时间和摄取含氟食物所带来的影响。作者选择了某电子工厂250名接触氢氟酸的工人为观察对象,以1,600名不接触氟的工人作为对照,年龄在15～59岁。样品测定分析采用氟离子选择电极法并用电位记录器进行。结果表明,非接触氟的正常人尿、血清中
In recent years, occupational exposure to fluorine has been on the rise. There is an urgent need to strengthen the health management of these workers and to study specific indicators of health management as a positive preventive measure. The author from this point, urine, serum fluorine content determination. In order to elucidate the significance of this measurement, urine, serum fluorine content and urine and serum fluorine content caused by exposure to relatively low concentrations of hydrogen fluoride were examined in non-contact fluoride-exposed general workers. The sample collection time And the effects of taking foods containing fluoride. The authors selected 250 workers exposed to hydrofluoric acid in an electronics factory as the object of observation, with 1,600 non-fluoride workers as controls, aged 15- 59 years. Samples were analyzed by fluoride ion selective electrode method and potential recorder. The results showed that non-contact fluoride in normal urine, serum
