Water fluoridation analysis of Campo Grande (MS) urban zone public supply

Abstract

The objective of this study was to analyze the fluoride concentration on the water that flows of the tap in the urban area of the city of Campo Grande (MS). For the fluoride concentration analysis, it was collected water samples of 21 schools placed in the 7 sub districts of the city, in 3 different opportunities, was made by the specific electrode method (using an Orion 9609 BN combined fluoride measuring electrode, coupled with an Orion EA-940 digital potentiometer). The results showed that 63.5% of the water samples presented acceptable fluoride levels (between 0.60 and 0.80 ppm) and 36.5%, unacceptable levels. In relation to the condition of the collect places, 76.2% were considered appropriate and 23.8% were inappropriate.
