The purpose of this study was to classify brands of bottled water by manufacturer assigned labeling to verify the concentration of fluoride for those brands that claim to contain fluoride, and to determine the existence and concentration of fluoride for those brands that do not cite fluoride or list it as undetermined on the product label.
A convenience sample of bottled drinking waters (N = 65) sold throughout the state of West Virginia was obtained for this study. Among the 65 brands, six different types of water were identified based on common wording displayed on the package. A sample (150 mL) was taken from each brand of water. Each sample was analyzed using an Orion EA940 microprocessor which calculates the fluoride concentration of a given sample. All analyses of bottled waters were reported using an inorganic chemistry laboratory report.
Results, reported in frequencies and percentages, indicate that only 12.3% (N = 8) of the brands tested contained an optimal level of fluoride (0.6 to 1.2 parts per million); 95% of the bottled water analyzed did not list fluoride; 1.1% (N = 7) of the bottled waters analyzed were obtained from municipal sources; and of the sixty-five brands tested, only three brands contained a fluoride concentration consistent with that listed on the label or as identified by the manufacturer.
Several main points can be summarized: 1) solely drinking bottled water may not provide sufficient fluoride to maintain optimal dental health; 2) most bottled waters contain low concentrations of fluoride and therefore, in and of themselves are not a risk for fluorosis; and 3) bottled waters are named and packaged in a variety of ways; however, their composition is virtually the same.
本研究的目的是根据制造商指定的标签对瓶装水品牌进行分类，以核实那些声称含有氟化物的品牌中氟化物的浓度，并确定那些在产品标签上未提及氟化物或列为未确定的品牌中氟化物的存在情况和浓度。
本研究获取了在西弗吉尼亚州各地销售的瓶装饮用水的便利样本（N = 65）。在这65个品牌中，根据包装上显示的常见措辞确定了六种不同类型的水。从每个品牌的水中抽取一个样本（150毫升）。使用Orion EA940微处理器对每个样本进行分析，该处理器可计算给定样本的氟化物浓度。所有瓶装水的分析均使用无机化学实验室报告进行报告。
以频率和百分比报告的结果表明，仅12.3%（N = 8）的测试品牌含有最佳水平的氟化物（百万分之0.6至1.2）；95%的分析瓶装水未列出氟化物；1.1%（N = 7）的分析瓶装水来自市政水源；在测试的65个品牌中，只有三个品牌的氟化物浓度与标签上列出的或制造商确定的浓度一致。
可以总结出几个要点：1）仅饮用瓶装水可能无法提供足够的氟化物以维持最佳口腔健康；2）大多数瓶装水含有低浓度的氟化物，因此就其本身而言不会导致氟中毒风险；3）瓶装水有多种命名和包装方式；然而，它们的成分实际上是相同的。
