摘要
大气中含有大量悬浮颗粒物,这些颗粒物表面吸附了来自燃料燃烧、机动车尾气、工业粉尘、废弃物燃烧等排放物,对人体健康的危害很大。其中空气动力学直径小于10 祄(PM10)的颗粒物危害尤其严重。叙述了室内外可吸入悬浮颗粒物PM10的类别、来源和特性,通过现场监测交通主干道旁室内外和远离主干道的室内外PM10的浓度,并分析了实验监测结果产生的原因和变化的规律。
In the ambient air, there exist a large amount of suspended particulates. Many pollutants, such as acid gases, heavy metals and organics etc. from industrial combustion processes, exhaust gases of motor vehicles and waste incineration, may be adsorbed on the surface of the particulates. The particulate pollutants, especially PM10, are thus seriously detrimental to health and daily life. In this paper, the categories, sources and characteristics of indoor and outdoor inhalable suspended particulates are described. Indoor and outdoor PM10 concentrations beside and far from a trunk road are measured. In addition, an analysis of the measurement results are carried out.
