INTRODUCTION
The concentrations of trace metals, ionic species, and carbonaceous components in PM(10) (particulate matter with aerodynamic diameters smaller than 10 µm) were measured from samples collected near an industrial complex, primarily composed of cement plants, in southeastern Spain, from September 2005 to August 2006.
MATERIALS AND METHODS
Positive matrix factorization and conditional probability function were applied to this data set to identify different types of sources.
RESULTS
Six significant sources were identified: crustal matter, traffic, aged sea salt, industrial emissions, secondary aerosol, and sea salt. The difficulty of separating anthropogenic sources from those of natural origin is highlighted in this study; in particular, the crustal source can be connected with both natural (African outbreaks, wind resuspension) and man-made emissions, like fugitive emissions in an industrial environment.
简介
本研究于 2005 年 9 月至 2006 年 8 月期间，在西班牙东南部一个主要由水泥厂构成的工业综合体附近采集 PM10（空气动力学直径小于 10μm 的颗粒物）样本，测量其中痕量金属、离子种类和含碳成分的浓度。
材料与方法
本数据集应用正矩阵因子分解和条件概率函数来识别不同类型的污染源。
结果
本研究共鉴定出 6 种主要污染源：地壳物质、交通、老化海盐、工业排放物、二次气溶胶和海盐。本研究强调了区分人为源和自然源的困难；特别是，地壳源可能与自然（非洲爆发、风力扬尘）和人为排放（工业环境中的无组织排放）有关。
