Fluoride
A survey on fluoride, nitrate, iron, manganese and total hardness in drinking water of Fereidonkenar, Northern Iran during 2008-2013
The purpose of present study was to evaluate fluoride, nitrate, iron, manganese and total hardness in drinking water of wells and reservoirs in Fereidonkenar, Mazandaran, Northern Iran and compare the results with national and international standards.
Spatial distribution of fluoride in groundwater resources in selected parts of Kurdistan Province, Iran, using the
Fluoride in drinking water has a profound effect on teeth. Since drinking water is an important source of fluoride, the evaluation of the fluoride content of water resources is necessary.
Temporal and spatial variation of drinking water quality in a number of Divandareh villages, Iran: With emphasis on fluoride distribution
Fluoride is found in all water resources at different concentrations and drinking water is the major source of fluoride exposure. Thus, because of the adverse effect of fluoride in low and high concentrations, the evaluation of its content in drinking water is necessary. In the present study, the temporal variations and spatial distribution of fluoride concentrations in the drinking water of villages in Divandareh (Kurdistan, Iran) were determined.
