This study aimed to monitor the fluoride concentration in the public water supply in Teresina, Floriano, and Parnaíba, Piauí State, Brazil. Samples were collected monthly for one year between 2004 and 2005. Six sites in each city were randomly selected for water sampling (total n = 576), 192 in each city. Fluoride assays were performed in duplicate, using a specific electrode. Most samples were below the optimum fluoride concentration, and only 4.3% (n = 25) presented acceptable values (0.60-0.80 ppm). Acceptable samples totaled 7.8% (n = 15), 4.7% (n = 9), and 0.5% (n = 1) in Teresina, Floriano, and Parnaíba, respectively. By conclusion, fluoride levels in the public water supply in the three cities were below the optimum concentration, and a permanent surveillance system is thus needed to guarantee effective water fluoridation in the State of Piauí.
本研究旨在监测巴西皮奥伊州特雷西纳、弗洛里亚诺和帕纳伊巴公共供水系统中的氟化物浓度。在2004年至2005年期间，每月采集样本，为期一年。每个城市随机选择六个地点进行水样采集（每个城市共192个，总计n = 576）。使用特定电极对氟化物进行双份测定。大多数样本低于最佳氟化物浓度，只有4.3%（n = 25）的样本呈现可接受值（0.60 - 0.80 ppm）。在特雷西纳、弗洛里亚诺和帕纳伊巴，可接受样本分别占7.8%（n = 15）、4.7%（n = 9）和0.5%（n = 1）。综上所述，这三个城市公共供水系统中的氟化物水平低于最佳浓度，因此需要一个永久性监测系统来确保皮奥伊州有效的水氟化处理。
