In the northern edges of the Tendurrek volcano (Northern White) a liter of some natural waters is 6.5 to 12.5 mgm. In this study initiated on the fluoride confirmation, fluoride analyses were made in some sources of water taken from the districts of Chaldyran (Tendürek volcano), Tatvan (Nemrut volcano) and Sarısu (Suphan volcano) around Lake Van. According to the color method of acid-circonium alizarin, the quantities of fluoride determined by colorimetre are mgm per liter. In the area of 2.0 to 7.5, in the area of Tatvan 2.0 to 5.0 in the area of Sarısu 'is between 0.2 and 0.7. The values that stole and find for the Tatvan areas are above the levels that are considered harmful to humans and animals in literature. There was a flora of teeth in humans and animals. There are five, six thousand humans and twenty, thirty thousand large and small animals that have been required to use high-dose fluoride resin water in the area for a long time, and there must be drinking water without fluoride as soon as possible. Furthermore, fluoride water should be used in moisture after mixing with clean water to prevent fluoride intake by animals through high doses of fluoride water infected with flushes and flushes. Summary FIuoride eontents of some of the natural waters around Lake Van and 1ts importanee. Some natural water samples used for drinking and irrigation purposes were eolleeted from the Lake Van, loeated in the eastern part of Turkey. The fluoride eoneentrations of standard solutions and water samples were determined by the eolorimetrje acid zirconium alizarin method The measured fluoride' coneentrations In five samples obtained from the Eolorimetrje acid zirconium were determined by the eolorimetrje acid zirconium alizarin method The measured fluoride' coneentrations In five samples obtained from the Eolorimetrje (Eolorimetrje) ranged from 2.0 to 7.5 mg./1. and three samples collected from Sunset (Suphan vokano) ranged from 0.2 to 0.7 mg: 1. and three samples from Sunset (Nemrut vokan) ranged from 2.0 to 5.0 mg./1. In addition to the dental fluorosis in some people, the occurenee of motled emal in the permanent teeth of eattle and sheep was also observed during the survey of the Stolen area. Dilution of fluoride rich waters with other suitable waters down to a safe level (2 ppm. ) was recommended to alleviete effects of fluorine on livestoek, human beings and also to protect the contarnination of soils and pastures,
