“…The abnormal level of fluoride in water is common in fractured hard rock zone with pegmatite veins (Ramesam and Rajagopalan 1985). Fluoride ions from these minerals leach into the groundwater and contribute to high fluoride concentrations (Suttie 1969;Jubb et al 1993;Schultheiss and Godley 1995). The concentration of fluoride in most waters is controlled by the solubility of the main fluoride-bearing mineral fluorite (CaF 2 ); hence, waters that are sodium (Na -), potassium (K -), and chloride (Cl -) rich and calcium (Ca -) poor tend to contain high fluoride concentrations.…”

The present study demonstrates a GIS-based spatial evaluation of fluoride contamination (FC) in groundwater vis-a-vis geology and geomorphology of the area using analytical hierarchy process and weighted sum method in Palamu district of Jharkhand. The integration and analyses of the various thematic databases along with the field sampled fluoride data proved useful in delineating the FC zones. The FC index ranged between 141 and 707, and was classified into four zones, viz., low, moderate, high, and very high zones of FC. The FC index map showed that a total of 49.75% of the study area lies between high to very high FC zone. The very high FC zone is found in the moderately weathered plateau with granitic terrain, whereas the high and moderately FC zones covering 49.31 and 36.41% of the study area are dominated by plateau weathered shallow, pediment-inselberg complex, pediplain moderately weathered, pediplain shallow weathered, and inselberg which have high fluoride. The lowest FC zone covers an area of 193.27 sq. km (13.84%). The spatial analysis of geology with fluoride showed that groundwater within granitic gneiss exhibits high FC followed by granitoid gneiss and alluvium. Geomorphologically highest FC was recorded in plateau weathered moderate (91.67%) followed by plateau weathered shallow (71.43%), flood plain (41.76%), inselberg (27.27%), and pediment (25%). The spatial analysis of groundwater yield with fluoride showed that regions having good yield exhibit maximum FC thereby accelerating the vulnerability of the population to fluorosis.

“…In recent decades, moreover, the environmental pollution with fluorine compounds is increasing not only due to the rapid development of industries that process fluorine compounds in large quantities, but also due to the increasing consumption of mineral fertilizers and pesticides (Suttie, 1969, Jubb et al, 1993, Schultheiss and Godley, 1995, Cronin et al, 2000.…”

Fluor je třináctým nejrozšířenějším prvkem na naší planetě a je tedy hojně zastoupen v životním prostředí (Mason a Moore, 1982). Vyskytuje se jak v půdě, tak i v rostlinách a živočiších, u kterých jej lze nalézt v kostech, zubech, měkkých tkáních i tělních tekutinách (National Research Council, 2005) a předpokládá se, že je esenciálním prvkem. Ve vyšších koncentracích však může způsobovat zdravotní problémy, které mohou končit i smrtí. K intoxikaci fluorem Vliv fluoru na zdraví zvířat a lidí

“…There was higher fluoride concentration in the northern part of the study area during both seasons. Fluoride ions from the minerals leach into the groundwater and contribute to high fluoride concentrations (Suttie 1969;Jubb et al 1993;Schultheiss and Godley 1995). pH is an important factor that has influence on fluoride ion concentration in drinking water, but the relationship between pH and fluoride is weak, because the increase in alkalinity is due to the increase of carbonate and bicarbonate ions.…”

Geochemical evaluation of fluoride contamination of groundwater in the Thoothukudi District of Tamilnadu, India

Fluoride is a chemical element that has been shown to cause significant effects on human health through drinking water. Different forms of fluoride exposure are of importance and have shown to affect the body's fluoride content and thus increasing the risks of fluoride-prone diseases. Fluoride has beneficial effects on teeth; however, low concentrations of fluoride intensify the risk of tooth decay. Fluoride can also be quite detrimental at higher concentrations at skeletal fluorosis. The Thoothukudi District is a hard rock and alluvial plain marked as one of the Fluoride-increase area in Tamilnadu due to occurrence of various rock types including fluoride-bearing minerals. The Fcontent of groundwater can thus originate from the dissolution of Fluoride-bearing minerals in the bed rock. Hundred representative groundwater samples from Thoothukudi District were collected during two different seasons. Samples were analysed for F-, other major cations and anions. The study area is chiefly composed of hornblende biotite gneiss, charnockite, alluvio marine, fluvial marine and granite with small patches of quartzite and sandstone. Higher concentration of fluoride is observed during pre-monsoon (3.3 mg l-1) compared to the postmonsoon (2.4 mg l-1) due to the dilution effect. Spatial distribution and factor score show that higher concentrations of Fare noted in the north and central part of the study area owing to lithology. Bicarbonate is well correlated with Fwhich explains that both ions were derived from the weathering. While Fhas a very weak correlation with pH which may be due to the increase of alkalinity resulting from the increase of carbonate and bicarbonate ions.
