“…Fluoride (F − ) is present in rocks, soil, air, water, and plants. While low intake of F − can be beneficial for teeth in humans (preventing caries) and bone growth, excessive F − concentrations can result in fluorosis and other adverse effects on human health, such as those regarding correct mental development in children, as previously shown by Oruc ( 2008 ), Yadav et al ( 2009 ), Patel et al ( 2014 ), and Yesilnacar et al ( 2016 ). In fact, Chen et al ( 2012 ) stated that fluorosis is becoming a global toxicological concern.…”

Effects of Changing pH, Incubation Time, and As(V) Competition, on F− Retention on Soils, Natural Adsorbents, By-Products, and Waste Materials

The purpose of this work was to elucidate the repercussion of changing pH, incubation time and As(V) competition on fluoride (F−) sorption on forest and vineyard soil samples, pyritic, and granitic materials, as well as on the by-products pine sawdust, oak wood ash, mussel shell ash, fine and coarse mussel shell, and slate processing waste fines. To reach this end, the methodological approach was based on batch-type experiments. The results indicate that, for most materials, F− sorption was very high at the start, but was clearly diminished when the pH value increased. However, oak wood ash and shell ash showed high F− sorption even at alkaline pH, and pine sawdust showed low F− sorption for any pH value. Specifically, F− sorption was close to 100% for both ashes at pH < 6, and around 70% at pH 10, while for forest soil it was close to 90% at pH < 2, and around 60% at pH values near 8. Regarding the effect of incubation time on F− sorption, it was very low for both soils, pyritic material, granitic material, and both kinds of ashes, as all of them showed very rapid F− sorption from the start, with differences being lesser than 10% between sorption at 30 min and 1 month of incubation. However, sawdust and slate fines sorbed 20% of added F− in 30 min, remaining constant up to 12 h, and doubling after 30 days. And finally, mussel shell sorbed 20% at 30 min, increasing to close to 60% when incubation time was 30 days. This means that some of the materials showed a first sorption phase characterized by rapid F− sorption, and a slower sorption in a second phase. As regards the effect of the presence of As(V) on F− sorption, it was almost negligible, indicating the absence of competition for sorption sites. In view of that all, these results could aid to appropriately manage soils and by-products when focusing on F− removal, in circumstances where pH value changes, contact time vary from hours to days, and potential competition between F− and As(V) could take place.

“…In many countries, groundwater is preferred as a source of drinking water over surface water because of its easy access and superior quality, such as lower levels of turbidity and microbial contamination (Mohebbi et al., 2013; Hybel et al., 2015; Abbasnia et al., 2018). However, groundwater may be contaminated by naturally occurring hazardous substances such as arsenic and fluoride (Brindha and Elango, 2011; Banerjee, 2015; Navarro et al., 2017; Yeşilnacar et al., 2016). In Viet Nam, Pakistan, Argentina, Myanmar, and Nepal, at least a million people are thought to have been exposed to arsenic (Ravenscroft et al., 2009; Augustsson and Berger, 2014; Bhowmick et al., 2018; Li et al., 2018).…”

Fluoride intake from tap water supplied by fluoride-containing groundwater has been the primary cause of fluorosis among the residents of Buak Khang Subdistrict, Chiang Mai Province, Thailand. To reduce fluoride intake, bottled water treated using reverse-osmosis membranes has been made available by community-owned water treatment plants. This study aimed to assess the resultant reduction in fluoride intake from using bottled water for drinking and cooking. Water consumption surveys were conducted by providing bottled water to 183 individuals from 35 randomly selected households and recording the amount of water consumed for drinking and cooking. The mean drinking water consumption was 1.62–1.88 L/capita/day and the cooking water consumption on weekends (5.06 ± 3.04 L/household/day) was higher than that on weekdays (3.80 ± 1.90 L/household/day). The per capita drinking water consumption exhibited a positive correlation with body weight; however, the low-weight subjects consumed more drinking water per kilogram of body weight than the heavy subjects. Although sex and day of the week did not significantly affect drinking water consumption per capita, girls consumed less water in school possibly due to their group mentality. Drinking water consumption per kilogram of body weight was significantly higher among women, children, and the elderly because these groups generally have low body weights. The fluoride intake from using tap water for drinking and cooking was estimated to be 0.18 ± 0.10 mg/kg-body weight/day and 5.55 ± 3.52 mg/capita/day, respectively, whereas using bottled water for drinking and cooking reduced the fluoride intake to 0.002 ± 0.002 mg/kg-body weight/day and 0.07 ± 0.05 mg/capita/day, respectively. Despite the increased cost, 98% and 90% of the subjects selected bottled water over tap water for drinking and cooking, respectively; thus, bottled water delivery services could be used to mitigate fluoride intake in developing countries.

“…As seen in studies in some parts of Turkey, fluoride concentration of water was found high from 1.5 to 13.7 mg/L due to the volcanic rocks and geothermal sources [11][12][13][14]. Yeşilnacar (2010) has first detected excessive fluoride in groundwater and dental fluorosis cases in Sarım and Karataş villages [15,16].…”

Dental fluorosis cases are observed due to the high consumption of high fluoride drinking water in some parts of Anatolia. Fluorosis is resulted from high concentrations of fluoride in groundwater and observed in some regions of Turkey having volcanic rocks and geothermal fields. Results of fluoride analyses showed that the concentrations in groundwater samples were above the admissible limit values for potable water (>1.5 mg/L). Objectives of this work are; to study the high fluoride in groundwater of Sarım-Karataş region, its health effects and to examine its removal efficiency from groundwater by electrocoagulation (EC). EC process including the electrodes, reactor and the power source successfully removed the fluoride from groundwater sample. F removal rate was found as ~96% at the end of 3 hour.
