Atmospheric particulate matter (PM) fractions (PM(10) and PM(2.5)) were sampled concurrently between June 2004 and May 2005 at two sites (urban and suburban) in Izmir, Turkey. The elemental composition of PM (Al, Ba, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, V, and Zn) was determined using inductively coupled plasma-optical emission spectrometer. Elemental compositions of several PM sources were also characterized. Positive matrix factorization (PMF) and chemical mass balance modeling (CMB) were applied to determine the PM sources and their contributions to air concentrations. The major contributors to PM were fossil fuel burning, traffic emissions, mineral industries and marine salt according to the PMF results. However, undetermined parts were more than 40%. On the other hand, the contributions to PM could be determined completely by CMB, and the dominant contributor was traffic with >70% at the two sites. Fossil fuel burning, mineral industries, marine salt and natural gas-fired power plant were the minor contributors.
2004年6月至2005年5月期间，在土耳其伊兹密尔的两个地点（城市和郊区）同时采集了大气颗粒物（PM）组分（PM10和PM2.5）。使用电感耦合等离子体发射光谱仪测定了PM的元素组成（铝、钡、钙、镉、铬、铜、铁、钾、镁、锰、钠、镍、铅、锶、钒和锌）。还对几种PM源的元素组成进行了表征。应用正定矩阵因子分解（PMF）和化学质量平衡模型（CMB）来确定PM源及其对空气浓度的贡献。根据PMF结果，PM的主要来源是化石燃料燃烧、交通排放、矿业和海盐。然而，未确定的部分超过40%。另一方面，CMB可以完全确定对PM的贡献，两个地点的主要贡献者是交通，贡献率>70%。化石燃料燃烧、矿业、海盐和天然气发电厂是次要贡献者。
