Study on Fluoride concentration levels and spatial distribution was carried out in a total of 366 drinking water sources in Arusha city, Ngorongoro, Arumeru, Monduli, Karatu, Meru, and Longido districts in Arusha Region, Northern... more
The presence of Fluoride ions in drinking water in concentration more than 1.5mg/lit is injurious to health. For this reason its removal is very essential from potable water. This paper describes the use of Zeolitic adsorbent (scolecite)... more
Background: Fluoride is an essential nutrient for the human body. The major routes of fluoride intake include food and drinking water, though the absorption of fluoride from food is much easier. The aim of this study was to evaluate the... more
The present study deals with the adsorption of fluoride by soil. The soil samples were taken from south east areas of Rajasthan .Various experiments have been carried out using batch adsorption technique to study the effect of main... more
Background and Objective: The use of packaged drinking water is on the rise nowadays in most countries, including Iran. Currently, more than 100 different brands of packaged drinking water are produced and distributed in Iran. This study... more
Estimation of water-soluble fluoride content is essential in polluted soils so that necessary corrective measures can be taken to prevent or minimize its entry into the food chain. Although fluoride can be estimated through titrimetry,... more
Groundwater is the main source of drinking water for many rural areas in the entire world. Fluoride is one of the main chemical elements that is found most frequently in the ground water and causes a significant hazard in the environment... more
Key words : Demineralization and remineralization begins with historical prespective on caries. Caries were identified as a major public health problem in 1940s. Demineralization is a process of removal of minerals from dental enamel.... more
We have developed a fluoride shuttle battery (FSB) which is a promising candidate for the next-generation high-energy-density secondary batteries. Using the bis [2-(2-methoxyethoxy) ethyl] ether (tetraglyme: G4) solvent containing 0.45... more
Hydrogeochemical investigations with emphasis on groundwater fluoride concentrations were carried out in the Shivani watershed area, Karnataka, South India. This drought-prone watershed is characterised by poor groundwater potential and... more
Due to Mexico's climate and environmental features, groundwater plays a very important role on Mexican economic activities and welfare. On average, groundwater extraction provides more than 60% of the national water supply. Groundwater... more
Analyse the effect of varnishes containing xylitol alone or combined with fluoride on the remineralization of artificial enamel caries lesions in vitro. Bovine enamel specimens were randomly allocated to 7 groups (n=15/group). Artificial... more
Unsur-unsur halogen (golongan VIIA) dalam sistem periodik meliputi F (fluorin), Cl (klorin), Br (bromin), I (iodin), dan At (astatin). Halogen sangat reaktif, sehingga di alam hanya ditemukan dalam bentuk senyawanya. Halogen berasal dari... more
This report documents the hydrogeological situation in the Oshivelo Region as it was known in 2004. Within the framework of the project nine boreholes have been drilled with the aim to investigate the Oshivelo Artesian Aquifer, especially... more
Potential of aluminium fumarate metal organic framework (MOF)for fluoride removal from groundwater has been explored in this work. The laboratory produced MOF exhibited characteristics similar to the commercial version. MOF was found to... more
Hydrochemical studies were conducted in Chinnaeru river basin of Nalgonda district, Andhra Pradesh, India, to explore the causes of high fluorides in groundwater and surface water causing a widespread incidence of fluorosis in local... more
In the frame of the Technical Cooperation project ‘Environmental Geology for Regional Planning‘ a hydrogeological study of the Chiang Mai / Lamphun Basin has been carried out. The main aim of this investigation was the provision of... more
Drinking water contamination by fluoride is recognized as a major public health problem in many parts of the world. In fact, although fluoride is an essential trace element for animals and humans, excessive fluoride intake may cause... more
Exposure of fluoride (F-) through drinking water and its adverse health effects have been reported in many parts of the world. Higher level of Fin groundwater has been reported from many parts of the developing countries and F-is endemic... more
Research Purpose The purpose of this research is to design and execute a study that describes the attitudes of San Marcos, Texas residents affected by the new public policy that ends fluoridation of municipal water supplies. Furthermore,... more
Adsorption is one of the method that is in use for remediation of contaminated water. The experimental factors affecting the batch mode of adsorption of various metals and inorganic anions are discussed in this book. The elemental... more

The problems related to groundwater contamination by Iron and Fluoride are common and serious all over the world, especially in developing countries. Excess amounts of these contaminants have created health problems. For this reason, the... more
Fluoride concentrations in Malawi's groundwater are primarily controlled by geogenic sources that are highly variable and may cause a heterogeneous fluoride occurrence and local-to-regional variations in fluorosis health risks posed. Our... more
The inorganic chemicals present naturally or due to human activity in soils, sediments and rocks enter, as point sources or non-point sources, into groundwater system and degrade its quality thus making it unusable for drinking and... more
— This paper aims to examine the treatment of aluminum fluoride-manufacturing wastewaters (AFMW) by adsorption on Tunisian natural clay using a two-level full factorial design. For this sake, three operating parameters supposed to affect... more
Objectives: A study was conducted with an objective to estimate the fluoride concentration in soil and crops grown over it which was not done before in Mathura city, Uttar Pradesh, India. Methodology and... more
Groundwater is the major source for various purposes in most parts of the world. Presence of low or high concentration of certain ions is a major issue as they make the groundwater unsuitable for various purposes. Fluoride is one such ion... more
