Abstract

Objectives: This investigation aimed to determine whether fluoride concentration in water at the user endpoint remains the same as at the adjusted source, i.e., water treatment facilities.

Methods: Daycares in Alberta, Canada, were used as the endpoint to measure fluoride concentration. They were randomly selected from a list of 400 licensed daycares provided by the Ministry of Children's Services. All water samples collected from the daycares were sent to the accredited Alberta Centre for Toxicology (ACFT) for analysis within 7 days of collection. ACFT used ion chromatography to determine fluoride concentration levels. Statistics analyses were conducted using the software SPSS 25.

Results: Water samples were collected from 141 daycares in 35 municipalities. In municipalities that adjust fluoride content, public water is supplied by 8 Alberta Environment & Parks regulated water systems. Fluoride concentration in water samples examined at the endpoint ranged from 0.58 mg/L to 0.79 mg/L. The differences between fluoride concentration at the water treatment facilities and the daycares ranged from -0.03 to 0.22 mg/L.

Conclusions: This study confirms that the concentration of fluoride adjusted at water treatment facilities in Alberta is maintained at endpoints at the approximate optimal level of 0.7 mg/L.

加拿大艾伯塔省水处理设施和终点之间调整后氟化物浓度的比较。

目的:本调查旨在确定用户端点的水中氟化物浓度是否与调整后的水源(即水处理设施)的浓度相同。方法:以加拿大阿尔伯塔省的日托中心为终点，测量氟化物浓度。他们是从儿童服务部提供的400家有执照的日托中心中随机挑选出来的。从日托所收集的所有水样都在收集后7天内送到经认可的阿尔伯塔毒理学中心(ACFT)进行分析。ACFT采用离子色谱法测定氟化物浓度水平。采用SPSS 25软件进行统计学分析。结果:收集了35个市141个日托所的水样。在调整氟化物含量的城市，公共用水由阿尔伯塔省8个环境与公园管理的供水系统提供。在终点检查的水样中的氟化物浓度范围为0.58毫克/升至0.79毫克/升。水处理设施和日托中心的氟化物浓度差异为-0.03至0.22毫克/升。结论:本研究证实，艾伯塔省水处理设施调整后的氟化物浓度在终点维持在0.7毫克/升的近似最佳水平。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
