摘要
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 evaluate the concentration of fluoride in the air of Nanzhuang, Xiaotang in Nanhai City and offer references for the water fluoridation schemes in the very areas. Methods 5 spots were selected respectively in the two towns. Air was collected 3 days in succession and 3 times a day. Then the air fluoride contents were measured with the fluoride-electrode method. Results The average air fluoride concentration of Nanzhuang is (0.0050±0.0029)mg/m 3, ranged from 0.0020 to 0.0140mg/m 3, and it's (0.0050±0.0022)mg/m 3, varied between 0.0008 and 0.0440 mg/m 3 in Xiaotang. Conclusions The air fluoride contents in both of the two towns are under the national permitted level.
