[Article in Portuguese] Abstract The aim of this study was to analyze legislative proceedings on fluoridation policies in Brazil from 1963 to 2019. The theoretical reference was Pierre Bourdieu. A document search was performed on legislative proceedings that address the theme of fluoridation in Brazil as a public health measure and the discussions in the […]
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 […]
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 […]
Abstract Purpose of Review Rapid economic growth and its huge population are putting tremendous pressure on water sustainability in China. Ensuring clean drinking water is a great challenge for public health due to water shortage and pollution. This article reviews current scientific findings on health-related issues on drinking water and discusses the challenges for safe […]
Eastern Oregon Healthy Living Alliance released a report detailing the impact of the Healthy, Happy Smiles, a school-based oral health program, for the 2019-2020 school year. Overall in the 2019-2020 school year, 51% of students returned parent consent forms, 42% of students received dental screenings, at least 36% of students received fluoride application and 14% […]
PFAS contamination was found in soil and water near an incinerator in New York state that has been burning firefighting foam for the Department of Defense. Industrial chemicals known as PFAS have contaminated soil and water near an incinerator in upstate New York that has been burning firefighting foam. The facility is run by Norlite, […]

Credit: Irasutoya, Michikazu Hara Caption: Ammonia (NH3) is one of the most important industrial chemicals today, synthesized globally for use in fertilizers that then enable food production for approximately 70% of the world’s population. Ammonia is currently obtained by reacting nitrogen (N2) from air with hydrogen (H2). This reaction requires high energy and is, therefore, […]
Note from Fluoride Action Network Structural formula for Isoxaflutole EU Hazard classification & labelling Warning! According to the harmonised classification and labelling (ATP07) approved by the European Union, this substance is very toxic to aquatic life, is very toxic to aquatic life with long lasting effects and is suspected of damaging the unborn child. Across […]
Highlights High F groundwater is distributed in central plain and coastal area of the NCP. Hydrochemical evolution along groundwater flow favors F mobilization in groundwater. Pore water compacted from clayey sediments had a high F concentration. Land subsidence causes the release of F trapped in strata into groundwater. Abstract Fluoride enrichment in groundwater at the […]
