Fluoride Concentration in Both Tap Water and Drinking Bottled Water (Commercial) in Baninah Area -Benghazi, Northeastern Libya

Abstract

Drinking bottled water has become both popular and increasingly controversial.  as a result of the use of these techniques, some of the necessary elements in water are exposed to remove it such as fluoride. For this reason, the present study aimed to determine the fluoride content in both Tap Water and some types of Bottled water (Commercial) in the Baninah area -Benghazi. Six different types of bottled water from the local market, and three sampling point of tap water (water network supply) were collected for analysis of pH, electrical conductivity (EC), total dissolved solids (TDS), and fluoride for all samples. The results revealed a decrease in total dissolved salts in some types of bottled water compared to the Libyan standard specifications for the quality of drinking water. While the Fluoride content in bottled water and tap water showed fluoride concentrations lower than 1.5 mg/l according to the WHO standards and Libyan standards for drinking water. This requires a medical study to know the other sources that compensate for the lack of fluoride in the water (tap water network supply - bottled water).
