尿氟正常值随地区、时间、对象和方法的不同而有差别。我市首次测定人群尿氟正常值,对诊断氟中毒及判断氟对环境质量和人群健康的影响有实际意义。一、方法 1985年6～10月,抽取潮阳、普宁、饶平、揭西和市区共五县(市)饮用低氟水(<0.5ppm)、无氟污染的城乡中不同年龄、性别、职业的健康者275名,取空腹晨尿,用氟离子选择电极法(质控误差<5％)测定其氟含量,求几何均值及单侧95％上限值,以t或t＇及F检验进行显著性检验。二、结果 275名中,男女之比为1:0.54,城镇与农村则为1:0.77,最小1岁,最大76岁。测定值经D检验,属正偏态分布,对数转换后近似正态分布。经方差分析,五县(市)男、女及男女合并后的几何均值的差别无统计
Urinary fluoride normal value varies by region, time, subject and method. For the first time in our city to determine the normal urinary fluoride in the crowd, the diagnosis of fluorosis and determine the impact of fluorine on environmental quality and population health is of practical significance. Methods From June to October 1985, low-fluoride drinking water (<0.5ppm) was collected from five counties (cities) in Chaoyang, Puning, Raoping, Jiexi and urban areas. Occupational health 275, take fasting morning urine fluoride ion-selective electrode method (quality control error <5%) determination of its fluorine content, the geometric mean and unilateral 95% upper limit to t or t ’and F Test for significance test. Second, the results of 275, the ratio of men and women 1: 0.54, 1: 0.77 in urban and rural areas, a minimum of 1 year old, maximum 76 years old. The measured value by D test, is a positive skewed distribution, logarithmic normal distribution approximation. By means of analysis of variance, there is no statistical difference between the geometric mean values of the male, female and male in the five counties (cities)
