Modeling the drivers of fine PM pollution over Central Europe: impacts and contributions of emissions from different sources

Original language description

Fine particulate matter (PM 2.5 ) is among the air pollutants representing the most critical threat to human health in Europe. For designing strategies to mitigate this kind of air pollution, it is essential to identify and quantify the sources of its components. Here, we utilized the regional chemistry transport model CAMx (Comprehensive Air Quality Model with Extensions) to investigate the relationships between emissions from different categories and the concentrations of PM 2.5 and its secondary components over Central Europe during the period 2018-2019, both in terms of the contributions of emission categories calculated by the particle source apportionment technology (PSAT) and the impacts of the complete removal of emissions from individual categories (i.e., the zero-out method). During the winter seasons, emissions from other stationary combustion (including residential combustion) were the main contributor to the domain-wide average PM 2.5 concentration (3.2 mu g m - 3 ), and their removal also had the most considerable impact on it (3.4 mu g m - 3 ). During the summer seasons, the domain-wide average PM 2.5 concentration was contributed the most by biogenic emissions (0.57 mu g m - 3 ), while removing emissions from agriculture-livestock had the most substantial impact on it (0.46 mu g m - 3 ). The most notable differences between the contributions and impacts for PM 2.5 were associated with emissions from agriculture-livestock, mainly due to the differences in nitrate concentrations, which reached up to 4.5 and 1.25 mu g m - 3 in the winter and summer seasons, respectively. We also performed a sensitivity test of the mentioned impacts on PM 2.5 on two different modules for secondary organic aerosol formation (SOAP and VBS), which showed the most considerable differences for emissions from other stationary combustion (in winter) and road transport (in summer).
