Highlights High-F– groundwater widely occurs in shallow aquifers of Kenyan Rift Valley. High-F– groundwater are Na-rich and Ca-poor with high pH and HCO3– concentrations. Dissolution of hyper-alkaline volcanic rocks, cation exchange and competitive anions contribute F–. Children suffer from high chronic health threats by groundwater fluoride ingestion. Abstract Widespread concerns about high-fluoride groundwater and their […]
A study by researchers at U of T and in Germany found that toothpastes containing hydroxyapatite appear to demonstrate either superiority or equivalency to fluoride toothpastes in fighting tooth decay (Photo by Ivan-balvan/iStock via Getty Images) Researchers at the University of Toronto’s Faculty of Dentistry have shown that new fluoride-free toothpastes with hydroxyapatite can […]
Some 85,000 NSW adults are currently on the public dental waiting list in NSW and it could be two or three years before they see a dentist. Of those, about 30,000 are in rural, remote or regional areas. A parliamentary inquiry investigating health outcomes and access in rural and regional NSW heard on Friday there […]
Highlights Debris-avalanche deposits dynamics trigger the widespread of fluoride in groundwater. Depth to groundwater enhances the variability of fluoride in volcanic aquifers. Safe groundwater for drinking purposes exists at steep slopes of stratovolcanoes. Deep fractured aquifers are potential sources of safe fluoride water. Irrigation agriculture enhances the variability of fluoride in shallow aquifers. Abstract Groundwater […]
PROVIDENCE, R.I. (WLNE)- The Center for Disease Control and Prevention has provided certificates to Providence and Cumberland for the 2020 Water Fluoridation Quality Award. The award recognizes those public water systems that adjust the fluoride concentration in drinking water and achieve a monthly average fluoride level that is in the optimal range for 12 consecutive […]
Fluorinated greenhouse gases (F-gases) contribute to climate change and in 2019 made up 2.3% of total EU greenhouse gas emissions. F-gases have a range of applications, particularly in the refrigeration, air conditioning and heat pump sector. Most F-gases have much higher global warming potentials than other greenhouse gases. This briefing outlines the important trends in […]
No contamination found The boil water advisory issued on Nov. 27 by the Simcoe-Muskoka Health Unit has been lifted as of Tuesday, Nov. 30. According to a press release issued at 11:30 a.m. by the health unit, laboratory tests confirmed there is no contamination and the water is safe to drink following the discovery of […]
Wairarapa councils have lost their say over fluoridation of their water supplies, which could come at an unbudgeted cost to ratepayers. Some councillors see it as another government mandate forced upon them in the Three Waters space. The government has passed a fluoridation bill that shifts the power of a local authority to introduce fluoride […]
New Delhi, Nov 29 (IANS): Fluorides, nitrates, arsenic and iron have been found above the optimum levels in the groundwater of 370, 423, 154 and 341 districts of the country, respectively, the Parliament was informed on Monday. The groundwater in 92 districts of 14 states is partially affected with lead, which can be harmful to […]
