S. Korean researchers successfully develop tools to accurately assess hydrogen fluoride quality
South Korean researchers have successfully developed a set of equipment that can provide accurate assessment of high-purity gases like hydrogen fluoride, which is used in semiconductor manufacturing. Such an achievement is deemed significant as it follows months-long struggle after Japan imposed export restrictions on the material to Seoul. “We have had limitations in carrying out […]

PHED: Potable water supplied to 85% of fluoride-hit areas
Jaipur: The PHED claimed that out of 6,849 habitations affected by fluoride in the state, 85% target have been achieved to provide safe drinking water in these areas. Drinking water supply has been achieved in 5,815 habitations, while work is in progress in this direction in the remaining 1,034 habitations. Principal secretary (PHED) Rajesh Yadav […]

FDA recommendations against mercury amalgam for children, pregnant women, and other vulnerable populations
Note from Fluoride Action Network, We want share this good news with everyone, albeit it took more than 30 years of campaigning to achieve this victory. Our sincerest gratitude to everyone who worked on this battle. (EC) WASHINGTON, Sept. 24, 2020 /PRNewswire/ — A broad array of consumer, medical, parents, and environmental groups are lauding a […]

Thermally treated Mytilus coruscus shells for fluoride removal and their adsorption mechanism.
Highlights Calcination increases fluoride adsorption capacity of Mytilus coruscus shells. An increase of calcination temperature from 700 °C to 800 °C increases fluoride removal sharply. The maximum fluoride adsorption capacity of MCS-800 is 82.93 mg/g. Fluoride removal by MCS-800 is achieved via precipitation by forming CaF2. Abstract We evaluated Mytilus coruscus shells (MCS) as an […]

Gem, a New Aussie-Made Toothpaste, is Free From Synthetic Nasties and Comes in Four Minty Flavours
… It also contains an oral probiotic to promote the growth of beneficial bacteria in the mouth and replace bacteria affected by harsh oral-hygiene regimes… In recent years, the word “natural” has popped up a lot, affixed to beauty products, fabrics, household-cleaning products and more, but it’s not always clear what it means. Cyanide and […]

Marysville water plant supervisor advocates for end of fluoride
The supervisor of Marysville’s water plants is advocating that the city abandon the use of fluoride, but officials haven’t formally responded after issues were raised this week. During a presentation Monday, Bari Wrubel, who oversees the water filtration and wastewater treatment plants, said city staff has been working in limbo after a leak in fluoride […]

British Fluoridation Society: plans and predictions in a post-COVID world
How important is fluoridation in a post-COVID world? The appeal of water fluoridation has never been greater. COVID-19 and the consequent imperative to avoid aerosol generating procedures (AGP) underscore how counter-intuitive it is to be treating disease when it could and should be prevented. COVID has informed us that we need to invest in public […]

Effective electrochemically controlled removal of fluoride ions using electrodeposited polyaniline-carbon nanotube composite electrodes.
Highlights PANI was electrodeposited onto a CNT-based substrate. PANI was in the partially oxidized emeraldine form and could participate in redox reactions. The PANI-CNTs composite is a promising redox-active electrode material. Enhanced fluoride removal was achieved by electrochemically controlled separation. The selectivity of fluoride over chloride was significantly enhanced. Abstract The objective of this study […]

Christchurch candidate’s secret fluoridation claims ‘ludicrous’
Claims the Government has secretly fluoridated parts of Christchurch have been slammed as “ludicrous”. New Zealand Public Party Christchurch East candidate Glen McConnell said water supplied to east Christchurch had been secretly fluoridated for almost a decade. McConnell posted the claim on his Facebook page, which has 297 followers, on September 17. “…does East Christchurch […]

Equilibrium sorption of fluoride on the activated alumina in aqueous solution.
Removal of fluoride is a desalination technology in which fluoride ions from aqueous solution are adsorbed on suitable adsorbent surfaces. In this study, adsorption potential was performed on both activated alumina (AA) and grinded activated alumina (GAA) by batch experiments for different contact time, pH, fluoride concentration, and adsorbent dose. Results indicated that adsorption occurred […]
