[Method] Using fluor reagent spec- trophotometry, fluoride concentration in the atmosphere in spring and winter of Baoding City was detection, and its air pollution by fluoride was assessed. [ Result ] In winter, atmospheric fluoride concentration in Baoding City was 0.009 -0.052μg/L, and the average detected rate of atmospheric fluoride concentration in the campus of Hebei University was 80%, In spring, atmospheric fluoride concentration was 0. 018 -0. 059 μg/L, and the detected rate was 94%. Compared with winter, air ＇pollution by fluoride was more serious in spring. During a day, the peaks of fluoride concentration in the atmosphere appeared from 10：00 to 11：00 or at 14：00. A rain could reduce fluoride concentration in the atmosphere and make the air clean. [Condusion] The research could provide scientific references for the effective control of air pollution by fluoride in Baoding City.展开更多
