【摘要】 可吸入颗粒物PM10对人体健康有很大的危害,其中细颗粒物PM2.5由于粒径小,容易进入人体细胞内部,其危害更大。山西省的大气颗粒物污染状况非常严重,污染物监测数据相对不足。鉴于以上情况,本文使用新型便携式空气质量监测仪,对太原市部分环境以及大同、临汾等地的PM10和PM2.5进行了监测与研究,并分析了污染成因,得出一些初步结论。 实验共五个部分,分别是:办公室室内外的监测,交通要道的监测,烧烤点的监测,太原、大同、临汾三城市的监测以及三户不同燃烧方式家庭的监测等。 监测数据分析结果表明:1)办公室室内外的颗粒污染物浓度严重超标,颗粒物污染程度大小为吸烟室>无烟室>室外,抽烟对室内污染影响较大,可引起颗粒物浓度的瞬时提高;2)太原市和平南路交通要道的颗粒物污染整体水平较高,PM2.5主要来自汽车尾气,PM10则主要来自地面扬尘:3)烧烤点颗粒物污染严重,PM2.5和PM10显著线性相关,PM2.5在PM10中所占比重为0.645;4)太原、大同和临汾三个城市的颗粒污染物浓度值高于国家标准,并高于其它地市的平均水平,呈现出采暖期劣于非采暖期的时间变化规律以及南部劣于北

【Abstract】 Inhalable particulates PM10 do great harm to the human health, among which the fine particulates PM2.5 are more harmful because they are easy to enter the human cell. The pollution state of atmospheric particulates in Shanxi Province has been quite serious, however its monitored data is insufficient relatively. In order to understand the air pollution here deeply, with new portable instruments, a series of measurements on the concentration of inhalable particulates of some areas in Shanxi Province were carried out and the pollution reasons were analysed, then some preliminary conlusions were drawn in this paper.The experiment consists of 5 parts: indoor and outdoor monitoring of a common office; study on the traffic road; monitoring of the roasting spot, monitoring in three cities of Taiyuan, Datong and Linfen, and monitoring of three households using different fuels in a village-in-town in Taiyuan.Analyses of the date showed that: 1) indoor and outdoor particulates concentration of the office was over the national standard heavily, the
