Milestone in the battle against arsenic- and fluoride-contaminated drinking water
Over 300 million people worldwide use groundwater contaminated with arsenic or fluoride as a source of drinking water. The Swiss Federal Institute of Aquatic Science and Technology (Eawag) has developed a method whereby the risk of contamination in a given area can be estimated using geological, topographical and other environmental data without having to test […]

Using High Fluoride Concentration Products in Public Policy: A Rapid Review of Current Guidelines for High Fluoride Concentration Products.
Abstract: Despite improvements in dental caries levels since the widespread introduction of fluoride toothpastes, it is still a disease which is considered to be a priority in many countries around the world. Individuals at higher risk of caries can be targeted with products with a high fluoride concentration to help reduce the amount and severity […]

Simplifying Solar Cells with a New Mix of Materials
An international research team has simplified the steps to create highly efficient silicon solar cells by applying a new mix of materials to a standard design. Arrays of solar cells are used in solar panels to convert sunlight to electricity. The special blend of materials — which could also prove useful in semiconductor components — […]

Greenpeace survey finds nine in 10 water-repellent outdoor apparel products contain harmful chemicals
Greenpeace called for a complete detoxification of water-repellent outdoor apparel after its survey found nine in 10 of them made with harmful chemical compounds could weaken human immune systems and even cause cancer. The survey was part of a joint effort from 19 countries and regions last November to collectively test 40 popular products, named […]

Is Fluoroquinolone Toxicity Quinolone Toxicity or Fluorine Toxicity?
As should be obvious from their name, FLUOROquinolones are fluorinated drugs. A little history for you: Nalidixic Acid is the backbone of all fluoroquinolones. It was discovered by George Lesher in 1962, and it started to be used as an antibiotic in 1967. Nalidixic acid, and the first-generation quinolones that were derived from it, were […]

Removal of fluoride by aluminum impregnated coconut fiber from synthetic fluoride solution and natural water
Abstract Aluminum impregnated coconut fiber ash (AICFA) was used for removal of fluoride from synthetic fluoride solution. The AICFA showed high specific area and strong affinity toward fluoride. Synthesized AICFA was characterized by pHZPC, FTIR, SEM and XRD studies. Adsorption kinetics indicated that the adsorption equilibrium was reached within 60 min and the adsorption process followed […]

Is Your Tea Wrecking Your Health?
If you believe that drinking tea is good for your health, you may be right. Tea, especially green tea, has been linked to a lower risk of cancer, stroke, heart failure, and diabetes. But tea can contain large amounts of fluoride and pesticides and be very bad for your health, so bad that it’s downright […]

Milky Way supernovae may help explain fluorine’s origin
Astronomers based in the US may have uncovered one of the reasons why fluorine exists on Earth and throughout the Milky Way galaxy. Their observations suggest that neutrinos from exploding stars may stimulate fluorine production. Built in the 1960s, the Kitt Peak observatory in Arizona has been behind some of the most important astronomical discoveries […]

Relaunching the power of fluorine
DuPont 2015 Chemistry Student Award winner Sébastien Alazet talks fluorine and how to reinvigorate a whole branch of chemistry… The fluorine atom is one of the most powerful atoms in the periodic table. Because of its specific properties – electronegativity, hydrophobicity and polarity – fluorine brings a crucial physico-chemical modification to molecules. Since isolation of […]

WHO. Guideline: Sugars intake for adults and children
Excerpts from report: Page 5 & 17: Although exposure to fluoride reduces dental caries at a given age, and delays the onset of the cavitation process, it does not completely prevent dental caries, and dental caries still progresses in populations exposed to fluoride (pages 23-35). Pages 14-15: The overall quality of the evidence pertaining to […]
