摘　　要：目的:测定南澳县水源水中氟化物的背景值及其它相关水质指标。方法:氟化物测定用茜素锆比色法;氨氮用纳氏比色法;亚硝酸盐氮用重氮化偶合比色法;硝酸盐氮用马钱子碱比色法;总硬度用EDTA滴定法。结果:21个水样中,有20个水样的氟化物含量均低于饮用水卫生标准(1 mg/L),仅有后宅的一口靠近海边水井的水中氟化物含量较高(2.4 mg/L)。结论:南澳县的水源属于低氟化物水源。Objective： To measure the background fluoride and related water quality indices in water source of Nan＇ao County. Methods： Fluoride, NH4^＋ , NO^- 2, NO^- 3 and total water hardness were measured according to standard methods. Results： The fluoride level of 20 samples from 21 tested water samples was less than 1 mg/L, and only one sample from a seaside tube well showed a high fluoride level（2.4 mg/L）. Conclusion： The background fluoride level of water source in Nan＇ao is lower than other places.
