[существительное] фторид
Тезаурус:
- Their inventions include:; chromium doped lithium-strontium aluminium fluoride (Cr:LiSAF) and chromium doped lithium-calcium aluminium fluoride (Cr:LiCAF) lasers; a hard X-ray lens and a semi-insulator detector.
- I clean them in the morning and also after each meal with Sainsbury's Oral Health anti-plaque toothpaste (with fluoride).
- Fluoride can be harmful; the key question is, at what concentrations does it become toxic in the body?
- Fluoride is now added to drinking water to protect teeth.
- We all know that fluoride is added to fight tooth decay but modern toothpaste also contains powdered chalk, aluminium oxide (found in cement) to remove plaque, and a derivative of seaweed which is used to thicken it.
- In January 1981, Emsley and others reported in the Journal of the American Chemical at Society (vol 103, p 24) that they had found a new strong hydrogen bond which formed between fluoride and amides - organic salts of ammonia.
- Are some people now ingesting too much fluoride from an increasing number of sources?
- fluoride leads to fewer teeth falling out which leads to more overcrowding and so extractions are needed.
- Back in 1945, when the first experimental fluoridation projects got under way in Grand Rapids, Michigan, and Newburgh, New York, it was envisaged that drinking about 1 litre of fluoridated water a day would provide 1 milligram of fluoride .
- First, people are now ingesting fluoride from many more everyday sources, including water, food, dental health products, and medicines as well as pesticide, insecticide and fertiliser residues and even the air we breathe.
- Add a small amount of cheap chemical called fluoride to a community water supply and Hey Presto! a costly and ubiquitous disease, tooth decay, is controlled.
- Veterinarians, horticulturists and environmental scientists have known for years that fluoride at very low concentrations can damage vegetation, aquatic life and livestock; chemists have learnt to expect the unexpected from this unpredictable element; and biochemists, physiologists and toxicologists all know that fluoride is a potent poison of enzymes.
