Additionally, 25 groundwater borehole sites were sampled in the Southern Region (specifically the LSB) by Bath (1980) during his ‘Bath, 1980 survey’ and shipped to the UK for lab analyses. Of the 25 samples, 2 samples had an ion balance over 5% and were excluded, with the remainder ...
4.3. Hazard map We created a hazard map of geogenic groundwater fluoride contamination for the whole of Ghana (Fig. 4), where high concentrations of fluoride mainly affect the northeastern part of the country between the Northern region and the Upper East region. Fluoride contamination in this ...

(a cariogenic oral bacterium) and provided sucrose-containing food and water (Fig.5a). By feeding sugar-rich diet, tooth enamel progressively develops caries lesions (analogous to those observed in humans), proceeding from initial areas of demineralization to severe lesions characterized by enamel ...

(6 µg/kg b.w./day for a person of 70 kg) for adults in the UK had been estimated (EFSA2013; Taves1983). In Sweden, the fluoride intake of adults from food and beverages in areas with low fluoride concentrations in drinking water (< 0.4 mg/L) was estimated to be 0.4–1.0 ...
Data for the aluminium-fluoride-inhibited form were collected to 2.5 Å resolution on station 9.6 at the SRS (Daresbury, UK), λ = 0.87 Å. Both datasets were collected at 100K from a single frozen crystal, using a Mar Research image plate detector. Both the native and MgADP-AlF3 ...
