中学生宿舍空气中常见污染物的现况调查

目的　为了解中学生宿舍内空气中常见污染物状况。　方法　采用国家规定的标准方法 ,监测两所中学生宿舍内主要空气污染物 :CO2 、NO2 、SO2 、HCHO、NH3、细菌总数、可吸尘的浓度。　结果　除 CO2 、NH3、细菌总数分别仅有 2、1和 1个样本超过国家卫生标准。两所中学楼层间、早上和下午之间各项指标的比较在统计学上差异均无显著性 ;而 NO2 、NH3等指标的比较在统计学上差异有显著性 ( P<0 .0 5 ) ,中学各指标与大学生宿舍比较 ,差异有统计学意义 ( P<0 .0 1)。

The Spot Research on Ordinary Air Contamination in Student's Dormitory

Objective In order to explore the status of frequent air contamination in student's dormitory. MethodsThis paper adopted national standard methods to measure the concentration of several main in-door air contamination such as CO 2,NO 2,SO 2,CHOH?NH 3,total of bacteria and absorbable dust of high school student's dormitories. Results Except that CO 2,NH 3,total of bacteria had exceeded the national sanitation standard, the rest were under the normal range of the standard.In two high schools,among the floors and between the two measure time(one is morning, the other is noon) in a day, the comparisons of each item's index were insignificant different in statistis. But there were significant differences between two high schools and between high school and university.
