【摘要】 <正> 四十年代以来,国外对于自来水加氟区的居民总摄氟量进行了很多调查。广州市芳村地区从1965年开始自来水加氟防龋,自来水含氟量由0.2～0.3毫克/升提高到0.6毫克/升。为了瞭解居民每人每天平均总摄氟量,1980～1982年作了这个调查。 方 法 3～7岁儿童的食物调查在两个幼儿园进行,由幼儿园保健老师登记1981年3～5月份六天中165人每餐用于烹调和直接进食的食物品种及其重量。然后归入水,粮食,肉鱼蛋,蔬菜,食盐和食糖六类,计算出每人每天的平均进食量。再根据广州市食品含氟量计算更多还原

【Abstract】 The water supply in Fon-Cheng has been fluoridated since 1965. In March-May, 1981, the foods consumption of 165 kindergarten children was surveied for 6 days. According to the figures of fluoride content in foods determined by us, the estimated daily mean fluoride intake of 3~7 year old children is 1.21mg, including 0.90mg from water, 0.10mg from grains, 0.17mg from vegetables, 0.03mg from meat and egg and 0.02mg from salt and sugar.Also, estimated daily mean fluoride intake of adult is 2.11mg, including 1.50mg from water, 0.22mg from grains, 0.34mg from vegetables , 0.03mg from meat and egg and 0.02mg from salt and sugar.In January-June, 18~28℃ of daily mean temperature, the mean daily urinary fluoride excretion of 42 children of 3~7 year old is 0.74mg(750ml urine with 0.98ppm F- ) . That of 46 pupils of 9~14 year old is 1.22mg (803ml urine with 1.52ppm F- ) and that of 44 abults of 21~81 year old is 1.67mg( 915ml urine with 1.83ppm F-). These may be the reflections of daily mean fluoride intake.The daily total fluoride intake of residents in Fon-cheng is within the range of previous reports on daily total fluoride intake in fluoridated areas ( 0.99~3.6mg, abult ) and on optimum daily fluoride intake(l.5-5mg, adult) . This is one of the safety evidences of water fluoridation in Foncheng.更多还原
