很少有其他公共卫生措施比自来水加氟进行过更大的临床、实验室和流行病学的研究,和城镇全体居民的更大规模的临床试用,以及更受到赞成的或反对的人们的注意。1957年,在试用和研究的基础上,美国医学会发表了一个关于自来水加氟的态度的声明。以后由于继续的广泛研究进一步证实了氟这个重要的不可缺少的营养物质的安全和有效程度,所以现在修订了这个声明。从天然的或人工加氟到水中使达最适宜浓度(0.7—1.2ppm)的地区的流行病学研究说明这样的水应该终生饮用。许许多多有对
Few other public health measures have carried out larger clinical, laboratory and epidemiological studies than tap water and fluoride, and larger clinical trials of all urban residents, as well as more favored or opposed people's attention . In 1957, based on trial and research, the American Medical Association published a statement on the attitude of tap water to fluoride. As a result of extensive research that continues to confirm the safety and effectiveness of fluorine, an important and indispensable nutrient, the statement is now amended. Epidemiological studies from areas where natural or artificial fluoride is added to water to an optimum concentration (0.7-1.2 ppm) indicate that such water should be consumed for life. Many are right
