[Water fluoridation analysis of Campo Grande (MS) urban zone public supply]. / Análise da fluoretação da água de abastecimento público da zona urbana do município de Campo Grande (MS).

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.

Análise da fluoretação da água de abastecimento público da zona urbana do município de Campo Grande (MS) / Water fluoridation analysis of Campo Grande (MS) urban zone public supply

O presente estudo teve por objetivo analisar a concentração de fluoreto na água que flui das torneiras da zona urbana do município de Campo Grande (MS). Para tanto, foram coletadas amostras de água de 21 escolas situadas nos sete subdistritos da cidade, em três oportunidades diferentes para análise do teor de fluoreto, determinada pelo método do eletrodo específico (medidor de fluoreto combinado Orion 9609 BN, acoplado a um potenciômetro digital EA-940 da Orion). Os resultados mostraram que 63,5 por cento das amostras coletadas apresentaram níveis aceitáveis (entre 0,6 a 0,8 ppm) de fluoreto e 36,5 por cento, níveis inaceitáveis. Em relação à condição dos locais de coleta, 76,2 por cento foram consideradas adequadas e 23,8 por cento, inadequadas.
