尿氟增高是氟过量摄入的特异性指标,对于氟中毒的诊断和防治以及评价环境污染都有一定参考价值。但通常收集受检者24小时尿液的方法,繁琐不便。为方便留尿者和有利于大批检查起见,我们于1974年6～8月研究了我市某厂车间空气中氟化氢浓度平均4～6毫克/米~3条件下,接触氟化物工人同日晨尿与全日尿含氟量的差异问题。测定结果经统计学处理,二者之差异无显著意义。
Increased urinary fluoride is a specific indicator of excessive fluoride intake for the diagnosis and prevention of fluorosis and evaluate the environmental pollution have a certain reference value. However, it is inconvenient to collect the urine of the subject for 24 hours. In order to facilitate the retention of urine and facilitate a large number of checks, we studied in June to August 1974 the city plant hydrogen fluoride concentration in the air on average 4 ~ 6 mg / m ~ 3 conditions, contact fluoride workers on the same day morning urine And full-day urine fluoride differences. The results were statistically analyzed, no significant difference between the two.
