Fluorine (F) is an element found in the 7th group of the periodic table from the halogen family. It’s an element that most reactive as it only needs to gain one electron to form Fluoride ion (F-). It’s in this form of fluoride that is found in our drinking water also known as fluoridated water. Water, food and living organisms are exposed to inorganic fluorides and they are hydrogen fluoride (HF), calcium fluoride (CaF2), sodium fluoride (NaF), sulfur hexafluoride (SF6) and silicofluoride. Fluoride compounds are plentiful in the earth’s crust and naturally found in rocks, soils, salt and sea water, representing approximately 0.06-0.09%.
fluoride toxicity. More recent studies associate consumption of fluoridated water to health risks like ADHD and
Another issue of controversy is the safety of the chemicals used to fluoridate water. The most commonly used additives are silicofluorides, not the fluoride salts used in dental products (such as sodium fluoride and stannous fluoride). Silicofluorides are one of the by-products from the manufacture of phosphate fertilizers. The toxicity database on silicofluorides is sparse and questions have been raised about the assumption that they completely dissociate in water and, therefore, have toxicity similar to the fluoride salts tested in laboratory studies and used in consumer products (Coplan and Masters 2001). It also has been maintained that, because of individual variations in exposure to fluoride, it is difficult to ensure that the right individual dose to protect against dental caries is provided through large-scale water fluoridation. In addition, a body of information has developed that indicates the major anticaries benefit of fluoride is topical and not systemic (Zero et al. 1992; Rölla and Ekstrand 1996; Featherstone 1999; Limeback 1999a; Clarkson and McLoughlin 2000; CDC 2001; Fejerskov
Interesting facts: Fluorine is added in water in certain countries and used in toothpaste so that it can strengthen people’s teeth.
Fluoride in drinking water has been a hot topic in the past decade. Some communities are all for it and some are completely against it. With such a range of opinions on the matter some organizations have took it upon themselves to present the pros and cons of the fluoride to the public so they can make informed decisions. Often times these surveys are bias to one side or the other, so I shall be giving information on both sides of the issue, the future outlook, and my personal opinion in order to help inform you to decide on your own.
Fluoride has been used by people for many decades. The most common use is in toothpaste. Fluoride was added to toothpaste to lower the amount of dental cavities that one gets, and works by protecting the enamel (outer hard layer over the tooth). Another use of fluoride is in drinking water. It was added to drinking water to also help with tooth decay. Many people are debating whether or not this is truly safe. In the essay, “The Fluoride Conspiracy”, by Laurie Higgs, she talks about the use of fluoride drinking waters and dangers it brings by using logos, pathos, and ethos.
Department of Health and Human Services address some of the public concerns about water fluoridation such as its effects on health and its ethical implication in the community. Some of the concerns express by the public were: safety of fluoride additives, fluoride’s impact on the brain, specifically citing lower IQ in children, effects of fluoride in the endocrine system, and cost effectiveness. In all cases, it was determine that in a concentration of 0.7 milligrams per liter, fluorided water was safe for consumption. Legal implications about community water fluoridation have been thoroughly reviewed by the U.S. court systems and the results have always being that water fluoridation is a proper means of promoting public health and welfare. Also, it is important to have in mind, that the state and local governments decide whether or not to implement water fluoridation after considering evidence regarding its benefits and
What is Fluoride? How does fluoride help you? How does it work? Fluorides are compounds that have been combined with the element fluorine with another substance usually a metal (Cancer.org 2015). Fluoride is a naturally occurring element found in rocks, in soil everywhere, in fresh water and in ocean water (Fluoride information network 2015). Fluorides strengthen teeth already present inside the mouth. Once in the digestive tract they travel through the blood to areas with high
I have been assigned the role of the leader of Fluoride Action Network. The Fluoride Action Network is a non-profit organization and an international coalition seeking to broaden public awareness about the toxicity of fluoride compounds and the health impacts of current fluoride exposures. The organization’s mission is to “provide comprehensive and up-to-date information regarding all aspects of fluoride” and to “remain vigilant monitoring government agency actions that may impact public’s exposure to fluoride.”1
Are you aware that fluoride that is used to help keep teeth healthy is actually a harmful compound. The number of products that contain fluoride is actually quite high. Many people may not know it is also in our drinking water. The scary thing is fluoride is now classified as a neurotoxin.
How did it start you may ask, Body Fluoride has long since been introduced as being a health factor A. All the information is Fluoridation is not a natural process nature thought of it first that fluoride in high level occurs in fluoride water studies shown a segmented frog suffers significant damage including bone disease, changes in behavior and shorter life span
Fluoride compounds have been added to water supplies since as early as the 1950s because claims were made to support fluoride's use as a cavity preventer. However, studies conducted even decades before have shown that fluoride is an extremely hazardous substance that should be completely avoided. These views or claims about fluoride are just too contradictory, both cannot be true. Fluoride has hidden dangers that not enough people know about and should be removed from the water supplies despite false reports that it is actually beneficial, and the practice of water fluoridation should be completely eliminated.
American Dental Association (ADA) has written and article on “5 Reasons Why Fluoride in Water is Good for Communities”(ADA, 2017.). The ADA then proceeds to go into depth on each of these five topics, as I will summarize in my own words. First, fluoride prevents tooth decay by being present in the
The most common fluorine minerals are fluorite, fluorspar and cryolite (Fluorine). Fluorine is also the 13th most common element in the Earth’s crust (Fluorine). There is 950 mg/L of fluorine in the earth’s crust (Periodic). Fluorine is also in seawater. Around 2,400 tons of fluorine gas and 4,700,000 tons of fluorite are produced each year (Periodic). Fluorine production areas are primarily in Canada, United States, United Kingdom, Russia, Mexico and Italy (Periodic). Fluorine is most commonly combined with sodium to form sodium fluoride (NaF) to put into toothpaste (Periodic). A very interesting fact about fluorine is that it is added to city water supplies in the proportion of about one part per million to help prevent tooth decay (The Element). Hydrofluoric acid is used to etch glass, including most of the glass that is used in light bulbs (The Element). You cannot purchase straight fluorine due to it being highly
2.4. Adsorption isotherms, kinetics and thermodynamic studies 2.4.1. Adsorption isotherms Adsorption isotherms describe the equilibrium between the adsorbents and adsorbate to optimize the use of adsorbents and introduce a design and operation of adsorption systems by the correlation of experimental data through the theoretical equations. Isotherm studies were performed by mixing the optimum dose of both adsorbents with Pb2+ solution at different initial concentration (25-250 mg/l) and shaking for the optimum time at room temperature. The data was fitted into the following isotherms: Langmuir, Freundlich, Temkin and Dubinin-Raduskevich.
