ABSTRACT

The present work was conducted in a two-part study. In part I, the levels of indoor and outdoor PM₁₀, PM_2.5, and PM₁ was measured using real time GRIMM dust monitors. In part II, the performance of NAIs method was investigated on reduction of indoor concentration of PM in these residential buildings for the first time. Hourly average concentration and standard deviation (SD) of PM₁₀ in indoor and outdoor at residential buildings were 63.5 ± 27.4 and 90.1 ± 33.5 µg/m³, respectively. Indoor and outdoor concentrations of PM_2.5 in residential buildings were 39.4 ± 18.1 and 49.5 ± 18.2 µg/m³ and for PM₁ the concentrations were 4.3 ± 7.7 and 6.5 ± 10.1 µg/m³, respectively. We estimated that nearly 71.47% of PM₁₀, 79.86% of PM_2.5 and of 61.25% of PM₁ in indoor of residential buildings can be removed by negative air ions.

摘要

本研究分为两部分进行。在第一部分中，使用实时GRIMM灰尘监测仪测量了室内和室外PM ₁₀，PM _2.5和PM _1的水平。在第二部分中，首次研究了NAIs方法在降低这些住宅建筑物中室内PM浓度方面的性能。居民楼室内和室外PM _10的每小时平均浓度和标准偏差（SD）分别为63.5±27.4和90.1±33.5 µg / m ³。住宅建筑物中PM _2.5的室内和室外浓度分别为39.4±18.1和49.5±18.2 µg / m ³，对于PM ₁浓度分别为4.3±7.7和6.5±10.1 µg / m ³。我们估计，近71.47％的PM ₁₀，PM 79.86％的_2.5和PM的61.25％，₁室内住宅可以通过空气负离子被移除。
