Abstract

X-ray photoelectron spectroscopy (XPS) was used to determine the surface chemical composition of atmospheric particles (PM-10 and PM-2.5), collected in downtown Katowice, Upper Silesia, Poland, in the winter season (November and December 2000). Carbon- and oxygen-containing species dominated the particulate surface with traces of N, S, Si, Cl, Na, Zn, Al, Cu, Fe, Ca, K, Mg, Pb, and P present. Additionally, the size, morphology, and chemical composition of about 300 of the individual atmospheric particles were analyzed by high-resolution scanning electron microscopy and electron probe microanalysis. A number of aluminosilicates and metallic elements such as Fe, K, Mg, Zn, as well as rare earth elements, were detected by SEM. The results obtained show that the analyzed aerosol is of natural and anthropogenic origin. Particles containing sulfur compounds as well as oxygen and sodium in downtown Katowice come mainly from the east and southeast sectors.

摘要

采用X射线光电子能谱（XPS）测定了2000年冬季（11月和12月）在波兰上西里西亚省卡托维兹市中心采集的大气颗粒物（PM-10和PM-2.5）的表面化学成分。含碳和含氧物种在颗粒物表面占主导地位，同时存在痕量的N、S、Si、Cl、Na、Zn、Al、Cu、Fe、Ca、K、Mg、Pb和P。此外，通过高分辨率扫描电子显微镜和电子探针微分析对约300个单个大气颗粒物的尺寸、形态和化学成分进行了分析。扫描电子显微镜检测到了多种铝硅酸盐和金属元素，如Fe、K、Mg、Zn以及稀土元素。所得结果表明，所分析的气溶胶具有天然和人为来源。卡托维兹市中心含有硫化合物以及氧和钠的颗粒物主要来自东部和东南部地区。
