據(jù)美國(guó)食品藥品管理局（FDA）消息，為與美國(guó)公共健康服務(wù)部的用水健康建議保持一致，美國(guó)FDA提議瓶裝水氟化物含量不超過(guò)0.7 mg/L。

向水中添加氟化物，可防止兒童與成人蛀牙。然而兒童暴露于高濃度的氟化物會(huì)導(dǎo)致氟斑牙的出現(xiàn)。鑒于此，美國(guó)公共健康服務(wù)部對(duì)相關(guān)研究進(jìn)行了審查，對(duì)社區(qū)的供水體系提出了更合理的氟化物濃度。

部分原文報(bào)道如下：

In concert with a new U.S. Public Health Service （PHS） recommendation for fluoride levels in community water systems, the U.S. Food and Drug Administration （FDA） has letter to industry recommending that bottled water manufacturers, distributors and importers limit the amount of fluoride they add to bottled water so that it contains no more than 0.7 milligrams per liter （mg/L）。 The new PHS recommendation was developed by a panel of scientists from several federal agencies, who undertook an extensive review of the scientific literature on the relationship between fluoride intake and oral health.
