People consuming alkaline water for health benefits should have optimum fluoride and pH. Water fluoridation prevents caries.
To determine the fluoride concentration, pH levels, and relation between them in six different brands of alkaline water.
Randomly, six different alkaline water package bottles were selected for fluoride and pH analysis using an electrochemical probe method and electrometric method, respectively.
The mean fluoride concentration of tested samples was 0.212 ± 0.376 mg/L with the highest value in Aava alkaline water (1.03 mg/L) and the lowest in Kangen alkaline water (0.02 mg/L). The mean pH was 7.754 ± 0.672, much below the claimed values of the manufacturers. Kangen alkaline water had the highest pH (8.66), and Aava alkaline water had lowest pH (7.05). There was a statistically significant difference, < 0.001, between different brands of fluoride and pH levels. There was a negative correlation between fluoride and pH in alkaline water samples ( = 0.032).
Tested alkaline water bottles should adhere to its pH and should contain optimum fluoride. Concerned authorities should make sure the availability of optimum fluoride concentration and specify the pH level on the alkaline water bottle label for better consumer awareness and making an informed choice.
为了获得健康益处而饮用碱性水的人应确保水中氟化物含量和pH值达到最佳水平。水氟化可预防龋齿。
测定六种不同品牌碱性水中的氟化物浓度、pH值水平以及它们之间的关系。
随机选取六个不同包装的碱性水瓶，分别采用电化学探针法和电位测定法进行氟化物和pH值分析。
测试样品的平均氟化物浓度为0.212±0.376毫克/升，其中Aava碱性水中氟化物浓度最高（1.03毫克/升），Kangen碱性水中最低（0.02毫克/升）。平均pH值为7.754±0.672，远低于制造商宣称的值。Kangen碱性水的pH值最高（8.66），Aava碱性水的pH值最低（7.05）。不同品牌的氟化物和pH值水平之间存在统计学显著差异（<0.001）。碱性水样品中氟化物和pH值之间存在负相关（=0.032）。
测试的碱性水瓶应符合其pH值标准，并应含有最佳氟化物含量。有关当局应确保提供最佳氟化物浓度，并在碱性水瓶标签上标明pH值水平，以提高消费者的认知度，使其能够做出明智的选择。
