    2013年冬春季济南市某办公场所室内空气颗粒物质量浓度分析

    Particulate Matters in Indoor Air in Jinan During Winter and Spring of 2013

      摘要
    • 摘要:
      目的 了解冬春季节室内空气颗粒污染物污染水平。
      方法 于2013年1-5月工作日期间在济南市某办公场所采用LD-5C(B)微电脑激光粉尘仪对室内空气颗粒物PM10、PM2.5进行监测。
      结果 济南市冬春季节室内颗粒物PM2.5、PM10平均质量浓度分别为0.082、0.115 mg/m3; 采暖期室内PM2.5、PM10的质量浓度(0.152、、0.191 mg/m3)高于非采暖期(0.050、、0.079 mg/m3), 差异有统计学意义(P < 0.05);采暖期室内PM2.5/PM10为0.807, 非采暖期PM2.5/PM10为0.598, 差异有统计学意义(Z=4.917, P=0.001);室内外PM2.5相关系数r=0.878, P=0.001;室内外PM10相关系数r=0.701, P=0.001。
      结论 济南市冬春季节室内颗粒物污染较重, 室内外颗粒物质量浓度有较好的相关性, 采暖对室内细颗粒物浓度影响较大。

       

      Abstract:
      Objective To investigate the concentration of particulate matters in indoor air during the period of winter and spring.
      Methods PM2.5 and PM10 in indoor air were monitored with a LD-5C(B) microcomputer laser instrument in an office in Jinan during working days from January to May.
      Results The average concentration of PM2.5 and PM10 in indoor air was 0.082 mg/m3 and 0.115 mg/m3, respectively. The concentration of PM2.5 and PM10 in heating season increased from 0.050 mg/m3 and 0.079mg/m3 to 0.152 mg/m3 and 0.191 mg/m3, respectively(P < 0.05). The ratio of PM2.5/PM10 increased from 0.598 to 0.807 during the transition of non-heating period to heating period(Z=4.917, P=0.001). The correlation coefficient of PM2.5 and PM10 was 0.878 for indoor air(P=0.001) and 0.701 for outdoor air(P=0.001), respectively.
      Conclusions The pollution of particulate matters in indoor air was worse in the winter and spring than that in the other two seasons. The concentration of particulate matters in indoor air and outdoor air was tightly correlated. The influence of heating on the concentration of particulate matters in indoor air was great.
