Fluoride content of tank water in Australia

Abstract

Background: The aims of this study were to: (1) analyse the fluoride content of tank water; (2) determine whether the method of water collection or storage influenced fluoride content; and (3) survey participant attitudes towards water fluoridation. Methods: Plastic tubes and a questionnaire were distributed through dentists to households with water tanks in Victoria. A midstream tank water sample was collected and fluoride analysed in triplicate using ion chromatography Results: All samples (n = 123) contained negligible amounts of fluoride, with a mean fluoride concentration of <0.01 ppm (range: <0.01-0.18 ppm). No statistically significant association was found between fluoride content and variables investigated such as tank material, tank age, roof material and gutter material. Most people did not know whether their tank water contained fluoride and 40.8% preferred to have access to fluoridated water. The majority thought fluoride was safe and more than half of the respondents supported fluoridation. Fluoride content of tank water was well below the optimal levels for caries prevention. Conclusions: People who rely solely on tank water for drinking may require additional exposure to fluoride for optimal caries prevention.

Estimation of fluoride concentration in drinking water and common beverages in United Arab Emirates (UAE)

“…Another brand Arwa (produced locally in UAE) showed fluoride content of 0.04 mg F/L which is much lower than 0.5 mg F/L tested in a study where the water source was from Riyadh, Saudi Arabia (Aldrees and Al-Manea, 2010). Similarly, fluoride content of brand Evian found in our study was 0.1 mg F/L, which was again lower than seen in other studies conducted in a last decade (Aldrees and Al-Manea, 2010, Cochrane et al, 2014, Johnson and DeBiase, 2003, Zohouri et al, 2003).…”

“…Different methods and instruments have been used to estimate fluoride levels in drinking water such as Ion Chromatography (Cochrane et al, 2014), Colorimetric (Gail et al, 1987) Potentiometric (Egorov et al, 2008) and Spectrophotometric method (Zaher and Sameer, 2012). However, majority of research studies (Aldrees and Al-Manea, 2010, Christian et al, 2013, Cochrane et al, 2006, Consuelo et al, 2009), have used ion selective electrode method to measure fluoride content of drinking water as this method is simple, quick, accurate and reliable (Bratovcic et al, 2009, Burton et al, 1992, Rajkovic and Novakovic, 2007).…”

Fluoride ingestion and thyroid function in children resident of naturally fluoridated areas - An observational study

“…In the present study, the final villages for sampling were selected based on drinking water fluoride levels estimated as per APHA (1998) guidelines using ISE method. Different methods and instruments have been used to estimate fluoride levels in drinking water such as Ion Chromatography (Cochrane et al , 2014), (35) Colorimetric (Gail et al , 1987) (36) Potentiometric (Egorov et al , 2008) (37) and Spectrophotometric method (Zaher and Sameer, 2012) (38). We preferred ISE method because of its advantages like accuracy, speed, economy and sensitivity in comparison with other methods like UV/VIS spectroscopy.…”

Evaluation of Dental Caries and Fluorosis Prevalence of Children in Eskisehir

“…Günümüze kadar yapılan çalışmalarda sudaki florür iyonunun analizi için iyon seçici elektrot 57,58 ve iyon kromatografi yöntemleri kullanılmıştır. 57,[59][60][61][62] İyon kromatografi cihazının yeterli hız, hassasiyet, kolay kullanım, güvenilir klinik veriler sağlaması ve küçük miktarlardaki örneklerin bile analizini sağlaması nedeniyle 63,64 araştırmamızda kullanılan içme sularındaki florür iyonunun analizi için iyon kromatografi yöntemi tercih edildi.…”
