摘要
城市环境空气中的颗粒物可经过人的呼吸系统进入人体造成损伤,而机动车尾气是城市大气颗粒物主要来源之一,建立其成分谱是大气颗粒物来源解析的重要基础工作.为建立柴油车尾气颗粒成分谱,使用尾气流量计滤纸、车载滤膜采集仪、清扫流量管内壁三种不同方法对中型柴油车尾气颗粒物进行了采样.采用XRF光谱测定法分别对采样前后的滤纸、滤膜、聚乙烯袋进行元素分析,共检测了LE(原子序数<Mg)及Al、Mg等37种元素.应用单因素方差分析得出存在显著性差异的元素,共得到LE(89. 5882%),4种非金属元素Si、P、S、Cl(3. 2601%),及9种金属元素Al、Cr、Mn、Fe、Ni、Cu、Zn、Rh、Pd(1. 199%).
Particulate matter in the atmosphere of the city can enter the human body throughthe human respiratory system, which is one of the main sources of particulate matter in thecity. Establishing its composition is an important prerequisite for the analysis of the source ofatmospheric particles in the city. In order to establish the particle composition of exhaust gasof diesel vehicles, three kinds of different methods, exhaust gas flow meter filter paper, ve-hicle - mounted membrane filter gas collector and inner wall of purge flow tube were used tosample the exhaust particulates of medium - sized diesel vehicles in this paper. XRF spec-trometry was used before and after the sample filter paper, membrane, polyethylene bags forelemental analysis. LE （atomic number 〈 Mg） and A1, Mg and other 37 kinds of elementswere detected. One -way ANOVA was used to get the significant difference elements. A to-tal of LE （89. 5882% ） , four kinds of nonmetal Si, P, S, Cl （3. 2601% ） and nine kinds ofmetal elements Al, Cr, Mn, Fe, Ni, Cu, Zn（1. 199%）.
