Lignite mining operations and lignite-fired power stations result in major particulate pollution (fly ash and fugitive dust) problems in the areas surrounding these activities. The problem is more complicated, especially, for urban areas located not far from these activities, due to additional contribution from the urban pollution sources. Knowledge of the distribution of airborne particulate matter into size fraction has become an increasing area of focus when examining the effects of particulate pollution. On the other hand, airborne particle concentration measurements are useful in order to assess the air pollution levels based on national and international air quality standards. These measurements are also necessary for developing air pollutants control strategies or for evaluating the effectiveness of these strategies, especially, for long periods. In this study an attempt is made in order to investigate the particle size distribution of fly ash and fugitive dust in a heavy industrialized (mining and power stations operations) area with complex terrain in the northwestern part of Greece. Parallel total suspended particulates (TSP) and particulate matter with an aerodynamic diameter less than 10 microm (PM10) concentrations are analyzed. These measurements gathered from thirteen monitoring stations located in the greater area of interest. Spatial, temporal variation and trend are analyzed over the last seven years. Furthermore, the geographical variation of PM10 - TSP correlation and PM10/TSP ratio are investigated and compared to those in the literature. The analysis has indicated that a complex system of sources and meteorological conditions modulate the particulate pollution of the examined area.
褐煤开采作业和褐煤发电厂在这些活动周边地区造成了严重的颗粒物污染（飞灰和扬尘）问题。对于距离这些活动不远的城市地区而言，该问题更为复杂，因为城市污染源还会带来额外影响。在研究颗粒物污染的影响时，了解空气中颗粒物按粒径分级的分布情况已成为一个日益受关注的领域。另一方面，空气颗粒物浓度测量对于根据国家和国际空气质量标准评估空气污染水平很有用。这些测量对于制定空气污染物控制策略或评估这些策略的有效性（尤其是长期有效性）也是必要的。在本研究中，我们试图调查希腊西北部一个地形复杂的重工业区（采矿和发电站作业区）飞灰和扬尘的粒径分布情况。同时分析了总悬浮颗粒物（TSP）和气动力学直径小于10微米的颗粒物（PM10）的浓度。这些测量数据来自位于更大感兴趣区域内的13个监测站。分析了过去七年的空间、时间变化及趋势。此外，还研究了PM10与TSP的相关性以及PM10/TSP比值的地理变化，并与文献中的情况进行了比较。分析表明，一个复杂的源系统和气象条件共同调节着研究区域的颗粒物污染。
