To analyze the fluoride concentration in the public water supply at the area supplied by the Water Treatment Station of Bauru and classify the samples as acceptable or unacceptable according to the fluoride concentration.
Samples were collected from 30 areas at two periods, October 2002 and March 2003. The fluoride concentration in the samples was determined in duplicate, using an ion sensitive electrode (Orion 9609) connected to a potentiometer (Procyon, model 720). Samples with fluoride concentration ranging from 0.55 to 0.84 mg F/L were considered acceptable, and those whose concentration was outside this range as unacceptable. Data were analyzed by descriptive statistics.
The fluoride concentration of the water samples varied between 0.31 and 2.01 mg F/L. Nearly 56% of the samples were classified as acceptable.
The variations in fluoride concentration at the area supplied by the Water Treatment Station reinforce the need of constant monitoring for maintenance of adequate fluoride levels in the public water supply.
分析鲍鲁市水处理站供水区域公共供水中的氟化物浓度，并根据氟化物浓度将样本分类为可接受或不可接受。
在2002年10月和2003年3月两个时间段从30个区域采集样本。使用连接到电位计（Procyon，720型）的离子敏感电极（Orion 9609）对样本中的氟化物浓度进行双份测定。氟化物浓度在0.55至0.84mg F/L之间的样本被视为可接受，浓度超出此范围的样本则视为不可接受。数据采用描述性统计进行分析。
水样中的氟化物浓度在0.31至2.01mg F/L之间变化。近56%的样本被分类为可接受。
水处理站供水区域氟化物浓度的变化强化了持续监测以维持公共供水中适当氟化物水平的必要性。
