"Fluorides are released into the environment naturally through the weathering and dissolution of minerals, in emissions from volcanoes and in marine aerosols. Fluorides are also released into the environment via coal combustion and process waters and waste from various industrial processes, including steel manufacture, primary aluminium, copper and nickel production, phosphate ore processing, phosphate fertilizer production and use, glass, brick and ceramic manufacturing, and glue and adhesive production. The use of fluoride-containing pesticides as well as the controlled fluoridation of drinking-water supplies also contribute to the release of fluoride from anthropogenic sources. Based on available data, phosphate ore production and use as well as aluminium manufacture are the major industrial sources of fluoride release into the environment." "When fluoride was first added to water in the 1940s as a means of preventing tooth decay, not a single dental product contained fluoride: no fluoride toothpastes, no fluoride mouthrinses, no fluoride varnishes, and no fluoride gels. In the past 60 years, as one fluoride product after another entered the market, exposure to fluoride increased considerably, particularly among children. Exposure from other sources has increased as well. Other sources include processed foods made with fluoridated water, fluoride-containing pesticides, bottled teas, fluoridated pharmaceuticals, teflon pans, and mechanically deboned chicken." |

- "Many dental products now contain fluoride, including over 95% of toothpaste. Studies show that a significant number of children swallow more fluoride from toothpaste alone than is recommended as a total daily ingestion."
- "Even if you don’t live in a community that adds fluoride to its water supply, you will still be exposed to fluoridated drinking water. This is because once fluoride is added en masse to water it winds in almost all processed beverages and foods. In the U.S., studies have shown that sodas, juices, sports drinks, beers, and many other processed foods, including infant foods, now have elevated fluoride levels."
- "Due its toxicity, fluoride is used in some pesticides to kill insects and other pests. As a result of fluoride pesticide use, some food products–particularly grape products, dried fruit, dried beans, cocoa powder, and walnuts–have high levels of fluoride."
- "Brewed black tea averages about 3 to 4 parts ppm fluoride, while commercial iced tea drinks contain between 1 and 4 ppm. As a result of these elevated levels, numerous studies have linked excessive tea consumption to a bone disease (skeletal fluorosis) caused by too much fluoride intake."
- "Many pharmaceuticals are fluorinated, meaning they contain a carbon-fluorine bond. fluorine.” Although the carbon-fluoride bond in most drugs is strong enough to resist breaking down into fluoride within the body, this is not always the case as research has found that some fluorinated drugs, including cipro, do break down into fluoride and can thus be a major source of fluoride exposure for some individuals."
- "Foods made with mechanically separated meat (e.g., chicken fingers, nuggets, etc), contain elevated levels of fluoride due to the contamination from bone particles that occurs during the mechanical deboning processed. Mechanically processed chicken meats have the highest levels, with chicken sticks containing an average of 3.6 ppm."
- "Cooking food, or boiling water, in teflon pans may increase the fluoride content of food. In one study, it was found that boiling water in a teflon pan for just 15 minutes added an additional 2 ppm of fluoride to the water, thus bringing the final concentration to 3 ppm."
- "Fluoride is a common air contaminant in industrial workplaces. As a result, workers in many heavy industries — including the aluminum, fertilizer, iron, oil refining, semi-conductor, and steel industries — can be routinely exposed to high levels of fluoride exposure. In addition to being a significant risk factor for respiratory disease; airborne fluorides can be a huge daily source fluoride intake."
