目的
确定墨西哥两个社区瓶装水、自来水和氟化盐中的氟化物含量。
设计
从墨西哥城和韦拉克鲁斯分层随机采集水和盐样本进行氟化物分析。
方法
使用组合氟离子特异性电极分析样品。使用Student t检验和混合模型ANOVA比较结果。水氟值按类型、社区和采集区进行比较;盐氟值按社区和采集区进行比较。
结果
共采集自来水197份，瓶装水133份，含氟食盐20份。所有自来水的平均（+/- SD）氟化物含量为0.20 +/- 0.17 microg F/g（范围为0.01至0.88 microg F/g），所有瓶装水的平均（+/-SD）氟化物含量为0.24 +/- 0.24 microg F/g（范围为0.01至2.80 microg F/g）。该差异无统计学显著性。当按城市分析结果时，自来水样本之间的差异具有统计学意义。10个瓶装水样本含有超过可忽略不计的氟化物（范围从0.7-2.8微克F/g）。平均盐氟含量为230.0 +/- 49.8 microg F/g，在政府规定的水平范围内。
结论
一些水样的氟化物含量超过了最高推荐水平。盐氟化物水平在规定限度内。强烈建议监测瓶装水和自来水的氟化物含量。
AIM
To determine fluoride levels in bottled water, tap water, and fluoridated salt from two communities in Mexico.
DESIGN
Stratified random collection of water and salt samples from Mexico City and Veracruz, Mexico for fluoride analysis.
METHODS
Samples were analysed using a combination fluoride ion-specific electrode. Results were compared using Student's t-test and mixed-model ANOVA. Water fluoride values were compared by type, community and collection area; salt fluoride values were compared by community and collection area.
RESULTS
197 tap water samples, 133 bottled water samples and 20 fluoridated salt samples were collected. The mean (+/- SD) fluoride content for all tap water was 0.20 +/- 0.17 microg F/g (ranging from 0.01 to 0.88 microg F/g) and 0.24 +/- 0.24 microg F/g for all bottled water (ranging from 0.01 to 2.80 microg F/g). This difference was not statistically significant. When results were analysed by city, the difference between tap water samples was statistically significant. Ten bottled water samples contained more than negligible fluoride (ranging from 0.7-2.8 microg F/g). Mean salt fluoride content was 230.0 +/- 49.8 microg F/g, which was within governmental regulation levels.
CONCLUSION
Some water samples had amounts of fluoride exceeding the maximum recommended levels. Salt fluoride levels were within regulation limits. Monitoring of fluoride content of both bottled and tap water is strongly advised.
