Despite the various reduction policies that have been implemented across Europe in the past few years, Particulate Matter (PM) exceedances continue to be recorded. Therefore, with the principal aim to clarify the complex association between emissions and fine particles levels, this work evaluates the impact of the anthropogenic contribution to the fine PM chemical profile. The fieldwork was conducted during March in 2008 and 2013 and covers the periods before and during the economic recession. The experimental data were analyzed in parallel with the emissions from the Flexible Emission Inventory for Greece and the Greater Athens Area (FEI-GREGAA). The differentiation of the mass closure results’ and the aerosols’ character is also discussed in combination with the calculated PM_2.5-Air Quality Indexes. The peak in the PM load and the Particulate Organic Matter (POM) component was recorded in 2013, corresponding to the enhancement of the anthropogenic input. Although the monitoring location is traffic-impacted, the sector of heating, from both wood burning and fossil fuel, proved to be the driving force for the configuration of the obtained PM picture. Especially in 2013, its contribution was two times that of traffic. Finally, the low wind speed values led to the deterioration of the air quality, especially for the sensitive groups.

经济衰退期间（2008年3月与2013年3月）的雅典精细PM轮廓的差异：人为排放量变化的影响和相关的健康影响

尽管过去几年来欧洲已实施了各种减排政策，但仍记录了超出颗粒物（PM）的情况。因此，主要目的是弄清排放物与细颗粒水平之间的复杂联系，这项工作评估了人为因素对细颗粒PM化学成分的影响。实地调查于2008年和2013年3月进行，涵盖了经济衰退之前和期间的时期。与来自希腊和大雅典地区（FEI-GREGAA）的​​灵活排放清单中的排放同时进行了分析。还结合计算的PM _2.5讨论了质量封闭结果和气溶胶特征的区别。-空气质量指数。2013年记录了PM负荷和颗粒有机物（POM）组分的峰值，这与人为输入的增加相对应。尽管监视位置受交通影响，但来自木材燃烧和化石燃料的加热部分被证明是配置所获得的PM图片的驱动力。特别是在2013年，它的贡献是流量的两倍。最后，低风速导致空气质量恶化，特别是对于敏感人群。
