Thus, acute toxicity (LD 50) occurred between 26 and 102 mg/kg b.w./day, and chronic toxicity (LOAEL) between 4.3 and 7.6 mg/kg b.w./day fluoride (Fig. Fluoride is usually determined by means of an ion-selective electrode, which makes it possible to measure the total amount of free and complex-bound fluoride dissolved in water. For rainwater in which fluoride was present at a concentration of 10 µg/litre, a The most commonly cited health concerns related to fluoride and water fluoridation are bone fractures and skeletal fluorosis, decreased Examples of fluoride toxicity demonstrate its serious threat.
