摘要
分析了北方部分地区2005年前后住宅内PM10的测试数据,结果表明北方地区住宅内PM10浓度超过国内标准的比例接近1/3,超过美国现行标准的比例为87.9%;住宅内PM10浓度的平均值为119.2μg/m3,约60%住户的室内PM10浓度分布在区间75μg/m3和165μg/m3之间。简要分析了国内北方地区室内PM10超标的主要原因,并对控制室内PM10的污染提出一些建议。
The PMlo mass concentrations measured in residences of partly northern areas in China were analyzed in this paper. Results show that the rate of exceeding the Chinese National Standard （GB/T18883-2002） of PM10 mass concentration in residential houses accounts for nearly 1/3, but the rate of exceeding the ASHRAE （62-1999） is up to 87.9%. Datum collected also indicated that the average PM10 mass concentration in northern residences in China is 119.2μg/m3, and for about 60% residences, PM10 mass concentrations were between the 75μg/m3 and 165μg/m3. The main reasons causing the higher PM10 mass concentrations in northern residence are analyzed, and valuable suggestions for reducing the indoor PMl0 pollution are further given.
