Evaluation of high fluoride contaminated fractured rock aquifer in South Africa – Geochemical and chemometric approaches

Highlights • High F (>1.5) is noticed in 51% of locations which are not palatable. • High fluoride is associated with NaCl water types derived from natural processes and evaporation. • PCA and HCA analysis justify that mineral weathering, evaporation and wastewater infiltration regulate the water chemistry. • PHREEQC-Groundwater is undersaturated with Cl and SO4 […]

Federal Judge to Decide if Fluoride-in-Water Case Goes to Trial

Health advocates filed suit in 2016 to try to force EPA to reduce fluoride exposure Implications for other groups seeking to regulate chemicals The future of a suit challenging the EPA’s stance that fluoride in drinking water doesn’t pose unreasonable risks to young children is the focus of dueling motions before a federal judge in […]

Fluoride reactivation-enabled sensitive quantification of tabun adducts on human serum albumin by GC-MS/MS via isotope dilution.

Organophosphorus nerve agents inhibit the cholinesterase activity by phosphylation of the active site serine. The resulting phosphylated cholinesterase and adducts on human serum albumin (HSA) are appropriate biomarkers for nerve agents exposure. Several methods have been developed for the detection of nerve agents, including fluoride reactivation or alkaline cleavage. It was previously thought that some […]

Fluoride Q coming to Rangely ballot

RANGELY | The Town of Rangely will be the next local entity to decide if it wants to keep fluoridating the town’s water supply. The Board of Trustees approved a resolution Tuesday to present fluoridation to voters in the April election. The measure passed by a narrow margin in Meeker this month. Rangely trustees heard […]

Siemens revamps German substation – replacing SF6 with ‘clean air’

German transmission system operator TransnetBW has commissioned Siemens to retrofit a large substation as part of up grid upgrades needed to integrate more wind. Siemens will supply the new switchgear for the 380 kV Daxlanden substation in Karlsruhe, Baden-Wurttemberg. The commissioning of the turnkey solution at Daxlanden – one of the largest substations in Germany […]

Dentists continue to ignore fluoride’s effect on the brain

It is hard to believe that the NZ Dental Association is still calling for the Fluoridation (Health Amendment) Bill, a.k.a the Mandatory Fluoridation Bill, to be passed despite a bombshell study (Green et al) published in one of the world’s top medical journals this year, JAMA Pediatrics. The study found that fluoridated water was associated […]

Tatura residents fight for their water

Anti Fluoridation Action Group Spokesperson Sharon Hopkins continues to fight for Taturas water. The Anti-Fluoridation Action Group took to Melbourne last week, as members continued their fight to stop fluoride being added to Tatura’s water. Group spokeswomen Sharon Hopkins met with an adviser from the Department of Health and Human Services, the body responsible for […]

UNE and partners collaborate on strategy for preventing oral disease in rural communities

The University of New England Dental Hygiene Program, Maine Area Health Education Center (AHEC) Network, Partnership for Children’s Oral Health, and The Opportunity Alliance have partnered to provide opportunities for UNE health profession students to perform oral health screenings and fluoride varnishes to children in rural and underserved communities. Students will provide the services at […]

Bubbles and Dust: Experimental Results of Dissolution Rates of Metal Salts and Glasses From Volcanic Ash Deposits in Terms of Surface Area, Chemistry, and Human Health Impacts.

Abstract Explosive volcanic eruptions lead to ash deposition and subsequent leaching of contaminants into soils or surface water, impacting flora and fauna, including human health. This study determined the control of ash surface area and chemical composition on ash dissolution rates. Fresh, unhydrated ash samples from four contrasting volcanoes were analyzed in the laboratory. Column […]
