DETERMINATION OF FLUORIDE CONCENTRATIONS LEVEL IN DRINKING GROUND WATER IN SHENDI CITY, RIVER NILE STATE, SUDAN

Fluoride is one of the elements that impact human health at levels lower and higher than the standard, also is consider as a health problem in most areas of the world, where about 200 million people from 25 countries are exposed to high or low concentrations of fluoride from groundwater sources. This descriptive and analytical study was conducted in shendi City to identify concentrations of fluoride in ground water. 150 samples of ground water were tested per season (50 samples for each season), the water samples were collected from ground water sources (wells), distribution system and storage facilities that are used directly by community. Analyzing of samples had been completed according to standard methods for examinations of water, in this study used photometer device for determination concentrations of fluoride. Our study revealed that: the quality of ground water in study area is low fluoride content and below the optimum levels that recommended by WHO and SSMO guidelines for drinking water and seasonal variations have effects on fluoride's solubility and concentrations. Based on the findings of this study we recommend that: community must not depend totally on ground water as main source for fluoride, and community in study area should be use other sources for fluoride intake to obtain on daily required amount of fluoride for protection the health.
