This work presents information regarding PM10, PM2.5, Polycyclic Aromatic Hydrocarbons (PAHs), and trace elements that were obtained from two sampling stations, located in the region of Western Macedonia (North-Western Greece), over the course of a 12-month period. Τhe first sampling station was located near the village of Pontokomi (Station 1) and the second (Station 2) in the rural area of Petrana (Fig 1). Specifically, for each location, daily particulate samples PM10 (total 58 samples) and PM2.5 (total 64 samples) were collected. Moreover, and again for each location, 50 samples (22 PM10 and 28 PM2.5) were further analyzed for the determination of 15 (PAHs) and 72 samples (36 PM10 and 36 PM2.5) were further analyzed for the determination of a total of 17 trace elements. Thus, a total of approximately 10 samples per month was obtained from each sampling station (122 samples per sampling station over the course of 12 months). The samples were collected using two low volume samplers, LVS 3.1 and PNS16T-3.1 (Comde-Derenda GmbH). Trace elements were trapped using 47 mm glass fiber filters and were recovered using microwave extraction; for their determination, the graphite furnace atomic absorption spectrometry (GFAAS) technique was utilized. The PAHs were trapped with 47 mm quartz fiber filters and were analyzed using dichloromethane extraction followed by gas chromatography-mass spectrometry. This region of Western Macedonia has historically been the center of electricity production in Greece. Lignite is mined in open-cast mines and used as feed in a number of thermal power plants. At its peak, which was in the 1990's, the areas produced close to 70% of electricity in Greece. Since then, electricity production (and related activities) are in decline as, due to Greece's EU commitments, the region has entered a transition, post-lignite process.
这项工作展示了在12个月期间，从位于希腊西北部西马其顿地区的两个采样站获取的有关PM10、PM2.5、多环芳烃（PAHs）和微量元素的信息。第一个采样站位于庞托科米村附近（1号站），第二个（2号站）位于佩特拉纳的农村地区（图1）。具体而言，对于每个地点，每天采集PM10颗粒样本（共58个样本）和PM2.5颗粒样本（共64个样本）。此外，同样针对每个地点，50个样本（22个PM10样本和28个PM2.5样本）进一步用于15种多环芳烃的测定分析，72个样本（36个PM10样本和36个PM2.5样本）进一步用于总共17种微量元素的测定分析。因此，每个采样站每月大约获取10个样本（12个月期间每个采样站共122个样本）。样本使用两个低流量采样器LVS 3.1和PNS16T - 3.1（Comde - Derenda GmbH公司）采集。微量元素通过47毫米玻璃纤维滤膜捕集，并使用微波萃取法回收；为进行测定，采用石墨炉原子吸收光谱法（GFAAS）技术。多环芳烃用47毫米石英纤维滤膜捕集，经二氯甲烷萃取后采用气相色谱 - 质谱联用仪进行分析。西马其顿的这个地区在历史上一直是希腊的电力生产中心。褐煤在露天矿开采，并用作多个热电厂的燃料。在20世纪90年代达到顶峰时，该地区发电量接近希腊总发电量的70%。从那时起，由于希腊对欧盟的承诺，该地区已进入褐煤开采后的转型期，电力生产（及相关活动）一直在下降。
