fluoride in water causes dental fluorosis. But how exactly? This was not known till now. Scientists from Japan and usa have identified the molecule in the cell that makes one susceptible to fluorosis. They hope their findings would lead to a drug for the ailment that has no cure. It will also benefit those suffering from dental caries and damaged enamel. Millions of people, who drink
Where does it spring from? Fluoride is naturally present in rocks. It made its way into drinking water when people started using ground water instead of surface water. In the mid 1960s and 1970s when deep hand pumps were introduced, fluoride found its way into people
They call it the elixir of life but with changing times, water has also become a driving force in economic activities, traditionally in agriculture, and now increasingly in the industry.
No wonder, there has been a tendency to take for granted the availability of water and show scant responsibility to the understanding of the ecological processes that make it available to us.
This study was carried out to assess the fluoride concentration in groundwater in some villages of northern Rajasthan, India, where groundwater is the main source of drinking water. Water samples collected form deep aquifer based hand-pumps were analysed for fluoride content. Fluoride in presently studied sites was recorded in the ranges of 4.78 and 1.01 mg/l.
The removal of fluoride from synthetic sample by adsorption on activated carbon prepared from gulmohar fruit shell was studied to determine the effects of dosages and pH accordingly to equilibrium and kinetics. The removal of fluoride by adsorption was studied on two types of carbons i.e., physically activated and chemically activated with I.R's of 0.25, 0.50 and 0.75.
An investigation has been carried out for the evaluation of fluoride contamination in Sambher block of Jaipur district. Results were compared with standards as prescribed by ISI and WHO.
Ongole, Sept. 2: Like many other compounds, fluoride is good in small quantities and becomes harmful in large quantities. Doctors use fluoride in small quantities for the prevention of dental cavities in children. It is common practice to add very low concentrations of fluoride to tooth pastes and drinking water (less than 1ppm).
Ongole, Sept. 2: Lakhs of villages in India wrestle with health problems because of lack of potable water. But in 21 villages of Prakasam district, it is potable water which is the villain. Water with high fluoride content is turning out to be a slow poison for people in these villages.
"Special attention has to be given to drinking water and one must always use scientifically cleaned water. Awareness about this has to be spread among the rural people about this and programmes have to be undertaken about the same at the Grama Panchayat level,' said Taluk Panchayat President C R Yuvaraj.
He was speaking after inaugurating the National Drinking Water and Sanitation Programme at the Kolar Taluk Panchayat on Tuesday. The programme was organised by Taluk Panchayat and Grama Panchayat secretaries and Anganwadi workers.
