No Valid Evidence Exists to Prove Fluoridation Works, say Researchers
After reviewing all available fluoridation studies, the independent and trusted UK-based Cochrane group of researchers could not find any quality evidence to prove fluoridation changes the “existing differences in tooth decay across socioeconomic groups.” Neither could they find valid evidence that fluoride reduces adults’ cavity rates nor that fluoridation cessation increases tooth decay, reports the […]

Fluorosilicic Acid Market – Industry Overview and Key Factors
Albany, NY — Fluorosilicic acid is an organic liquid produced as by product of hydrogen fluoride and phosphoric acid production. It is generally used for fluoridation of water to maintain fluoride level in water by municipal corporations and in toothpastes. Maintaining fluoride levels helps in preventing tooth decay. Being a liquid, fluorosilicic acid is easy […]

Fluorourocil: Catheter studies raise acid alert
Chemotherapy treatments routinely deliver drugs via catheters, yet in 25% of these catheters there are complications that are generally not well understood. For the first time researchers have studied the behaviour of a common chemotherapy drug on silver, which is often used to coat catheters and other apparatus used in chemotherapy drug delivery. The studies […]

Fluorochemicals – Global Strategic Business Report 2015
Fluorochemicals, which are compounds with fluorine as a key component, are stable and highly resistant to chemicals and heat. Due to their inert [note from FAN: often biologically active] properties and stability, they are used in industries such as automotive, electrical, performance coatings, chemical processing, semiconductor and aerospace. Strong demand from major application areas, including […]

Rotten Roman Baby Teeth Blamed On Honey, Porridge
The ancient Romans were certainly not known for their impeccable dental hygiene. In an era before germ theory and before the invention of the toothbrush, Romans chewed on twigs and used toothpicks to clean their teeth of food particles, and in some parts of the Empire, people used crushed shells or pumice to smooth teeth […]

Perflorooctane sulphonate toxicity: Proteomics study of liver cell damage
Hepatotoxic perfluorinated chemicals Perfluorinated compounds are a group of manmade chemicals that were used for decades before their environmental significance was realised. Once they enter the environment they are incredibly stable and, along with several other groups of chemicals, have been labelled “emerging contaminants.” According to the US EPA, they are characterised by “a perceived, […]

Pregnancy serum concentrations of PFOA-PFOS and offspring behaviour and motor development at age 5-9 years – a prospective study
In animal studies, perfluorinated alkyl substances affect growth and neuro-behavioural outcomes. Human epidemiological studies are sparse. The aim was to investigate the association between pregnancy serum concentrations of perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) and offspring behaviour and motor development at 5-9 years of age. Methods: Maternal sera from the INUENDO cohort (2002-2004) comprising 1,106 […]

Global emission inventories for C4–C14 perfluoroalkyl carboxylic acid (PFCA) homologues from 1951 to 2030, part II: The remaining pieces of the puzzle
Highlights Eleven overlooked but (potentially) significant sources of PFCAs are identified. Substantial emissions may come from historical and current use of C4 and C6 PFCAs. Emissions from substances based on C4, C6 and C10 PASFs may be considerable. Degradation of HFCs, HFEs and polymers may be an abundant and long-lasting source. Critical knowledge and data […]

Lancet Neurology reclassifies fluoride as developmental neurotoxin
An average IQ decrement of about seven points in children exposed to raised fluoride concentrations When a Harvard professor speaks, one usually listens. Perhaps the results of a new article authored by Dr. Philippe Grandjean, Harvard School of Public Health, and Dr. Philip Landrigan, Icahn School of Medicine, will finally change public water policies on fluoridation of city water.
