目的 了解南海市南庄、小塘两镇空气氟含量 ,为在当地进行饮水氟化项目提供参考。方法 在南海的南庄、小塘两镇分别各设 5个采样点 ,连续 3天、每天 3次采集空气样品 ,检测空气氟含量。结果 南庄镇日均空气氟含量为 (0 .0 0 5 0± 0 .0 0 2 9)mg/m3 ,各次检测全距为 0 .0 0 2 0～ 0 .0 14 0mg/m3 ,小塘镇日均空气氟含量为 (0 .0 0 5 0±0 .0 0 2 2 )mg/m3 ,各次测量全距为 0 .0 0 8～ 0 .0 4 4 0mg/m3 。结论 两镇空气氟含量均低于国颁空气氟含量标准。
Objective To understand the fluorine content of air in Nanzhuang and Xiaotang of Nanhai and provide a reference for the fluoridation of drinking water in the local area. Methods Five sampling points were set up respectively in Nanzhuang and Xiaotang of the South China Sea. Air samples were collected three times a day for three consecutive days to measure the fluorine content in the air. Results The average daily fluoride content in Nanzhuang was (0. 00 ± 0 .0 0 2 9) mg / m3. The full range of detection was 0. 0 0 0 ~ 0. 0 14 0mg / m3 The average daily fluoride content in the town was (0. 00 ± 0 .0 0 2 2) mg / m3, and the full range of the measurements was 0 .080-0.0450 mg / m3. Conclusion The fluorine content of air in the two towns is lower than that of the national standard.
