News Archive
Welcome to the Fluoride Action Network News Archive. The FAN News Archive serves as an historical repository for fluoride news stories, positive or negative. Since FAN catalogs all news stories on fluoride, our news section remains a reliable database of all published fluoride news.
Our news database is categorized by country, state/province, and industry. This collection of articles is constantly being updated with the most recent global news on fluoride-related issues and events.
The increasing atmospheric burden of the greenhouse gas sulfur hexafluoride (SF6)
Abstract We report a 40-year history of SF6 atmospheric mole fractions measured at the Advanced Global Atmospheric Gases Experiment (AGAGE) monitoring sites, combined with archived air samples, to determine emission estimates from 1978 to 2018. Previously we reported a global emission rate of 7.3±0.6 Gg yr1 in 2008 and over the past decade emissions have […]
Rapid destruction of sarin surrogates by gas phase reactions with focus on diisopropyl methylphosphonate (DIMP).
Note from FAN: The molecular structure of Sarin: Abstract Rapid destruction of stockpiles of sarin and other chemical weapon agents (CWA) requires understanding and quantitative description of the relevant chemical reactions. Rapid reactions at elevated temperatures are of particular interest for prompt agent defeat scenarios. Diisopropyl methylphosphonate (DIMP) is a sarin surrogate particularly well suited […]
[Investigation and Analysis of Occupational Hazards and Control Measures in Waste Incineration Power Generation Enterprises]
Abstract in English, article in Chinese: Objective: To investigate occupational hazards in waste incineration power generation enterprises. Methods: From May 2016 to September 2018, four garbage incineration power generation enterprises in different regions and scales were selected as the survey objects. Investigated and analyzed the types of occupational hazards, workplace distribution and occupational disease […]
PVDF: Cracking in Solar Backsheets Not Correlated with Climatic Conditions: Report
The study analyzed data from 3 GW of solar installations, nine million panels, and 551 installations DuPont has released its ‘Global Photovoltaic Reliability Report’ with findings from studies conducted on solar modules across the globe to track material degradation and how it affects module performance. The 2020 field report tested around 3 GW worth of […]
Iron oxide nanoparticles modified with ionic liquid as an efficient adsorbent for fluoride removal from groundwater
Highlights IL-iron oxide NPs acts as an excellent adsorbent for fluoride adsorption since its ion pair attraction with the F–. Fluoride adsorption efficiency was achieved 96% in 30 min by IL-iron oxide NPs. Fluoride removal parameters on IL-iron oxide NPs have been optimized. Regeneration study showed 65% removal efficiency till 5th red Cycle. Abstract A […]
Remediation of fluoride contaminated water using encapsulated active growing algae
Highlights 60 % of fluoride was removed from 3 mg/L concentration using encapsulated living and growing algae. SEM- EDX and FTIR studies confirmed the biosorption of fluoride on algae. Bigger scale implementation of the concept is possible due to very simple separation operation of algae from treated water. Freundlich isotherm and first-order kinetics were fitted […]
Fluoride removal from groundwater using Zirconium Impregnated Anion Exchange Resin.
Highlights HAIX-Zr resin selectively removes fluoride and can be easily regenerated. HAIX-Zr resin shows higher defluoridation capacity than commonly used adsorbents. The presence of bicarbonate adversely affects fluoride removal by HAIX-Zr. Exchange of OH– with F– is the possible fluoride removal mechanism by HAIX-Zr. Abstract Drinking water containing excess fluoride is a major health concern […]
Bio-inspired materials for defluoridation of water: A review
Abstract The polluted water sources pose a serious issue concerning the various health hazards they bring along. Due to various uncontrolled anthropogenic and industrial activities, a great number of pollutants have gained entry into the water systems. Among all the emerging contaminants, anionic species such as fluoride cause a major role in polluting the water […]
Surprisingly high fluorine content in some exotic superfoods.
Highlights Superfoods are extremely popular because of supposed health benefits. Surprisingly high fluorine content determined in some superfoods (16.4–373?µg/g). Significant contribution to adequate intake of fluorine in non-fluoridated areas. Upper limit for fluorine in fluoridated areas can be reached Wise consumption is advised because of possible adverse effects of fluorine Abstract Recent years have seen […]
