Procedures used for measuring ionic fluoride in both human and cow's milk have been investigated. A number of factors were found to affect fluoride ion measurements in milk samples including time, stirring and the method of cleaning the fluoride electrode. Following these investigations a procedure was developed for estimating ionic fluoride in milk. Human milk collected from a fluoridated area (Newcastle-upon-Tyne) was found to contain significantly more ionic fluoride (0.065 ppm) than human milk from mothers in a non-fluoridated area (Dundee, 0.035 ppm).
