“…The main sources of fluoride in the environment are natural, such as volcanic emissions and marine aerosols [2]. Volcanic regions or regions with geothermal activity present high levels of fluoride in soils and water [3,4]. However, anthropogenic activities such as the use of pesticides, sewage, or industrial discharges cause an increase in fluoride concentration in the environment [5,6].…”

Fluoride is a halogen found in soil and water from natural and anthropogenic sources. Foods, such as cereals, fruits, and vegetables, among others, absorb and accumulate fluoride. High intakes of this element produce toxic effects such as dental or skeletal fluorosis. Fluoride content was determined in a total of 144 samples from different food groups (cereals and derivatives, fruits, tree nuts, dry fruits, mushrooms, vegetables, and legumes) using selective fluoride ion potentiometry. The fluoride concentration stood out in almonds (3.70 ± 0.96 mg/kg), walnuts (3.53 ± 0.62 mg/kg), bread (2.54 ± 0.85 mg/kg), and rice (2.28 ± 0.93 mg/kg). Consumption of 236 g/day of bread or 263 g/day of rice represents 100% of the recommended daily intake (DRI) set at 0.6 mg/day for children aged 1–3 years. In the case of rice consumption by children of these ages, it is recommended to use bottled water for rice preparation. The consumption of the analyzed foods by teenagers and adults does not pose a health risk.

“…A calibration curve was performed with solutions of known fluoride concentration (10 −1 , 10 −2 , 10 −3 , 10 −4 , 10 −5 M) (Rodríguez-Gómez et al, 2003;Rubio et al, 2020;Revelo-Mejía et al, 2021). The potential of the samples was measured, and the concentration was extrapolated using the semi-log calibration curve prepared above.…”

Fluoride concentrations of 0.5 mg/L in drinking water are considered useful for dental caries prevention. However, fluoride concentrations higher than 1.2 mg/L in water can pose a risk of dental fluorosis due to high exposure to fluoride. The objective is to determine the fluoride concentration in water from aqueducts of different Colombian municipalities of Cauca (Popayán, Coconuco, and Puracé) to assess the fluoride dietary intake from the consumption of this water. A total of 66 water samples have been taken from Popayán, Coconuco, and Puracé. Fluoride content was determined by fluoride ion-selective electrode (ISE) potentiometry. The fluoride concentrations recorded in Coconuco and Puracé water were ≤ 0.002 mg/L. The mean fluoride content recorded in the Popayán water was 0.42 mg/L, with its highest concentration in Cauca River water (0.83 mg/L). Considering the admissible intake values, the water from Popayán confers remarkable fluoride intakes, especially in children with high percentages of contribution to the admissible daily intake (46.7% to 7- to 12-month children and 41.5% to 1- to 3-year children). The fluoride content in the water of Coconuco and Puracé does not reach an optimal value (< 0.5 mg/L) for the protective effect against dental caries, while the water of the main Cauca River basin does reach the optimal value. Likewise, the intake of fluoride from the consumption of the analyzed water does not confer any health risk. However, the implementation of monitoring systems for fluoride levels is recommended in order to safeguard the consumer’s health.

“…The Canary Islands is a volcanic region whose porous and permeable soil makes its water sources rich in this anion, whose levels range between 0.35-6.94 mg/L. 17,18 Four of the 4 samples originating from the Spanish peninsular territory are produced in Murcia, which is a region in which the waters have fluoride levels below 0.6 mg/L, 19 which would explain this relevant difference.…”

“…This can be derived from the high levels of fluoride in the waters of Tenerife (0.35-6.94 mg/L), levels slightly higher than those in some areas of Mexico (4.8 mg/L). 18 The type of production was also taken into account. Regardless of flavour, organic juices and nectars are richer in fluoride (Table 6, Figure 8) which shows that organic products are not safer in terms of fluoride levels.…”
