Sources of PM$_x$ emissions in Germany

Identification of major emission sources is essential for clean air policy. A detailed emission inventory of primary PM, PM$_{10}$ and PM$_{2.5}$ has therefore been developed in Germany. In this chapter the used methodology and data sources for emission calculations are described and resulting emission data are presented. As major sources diesel engines, solid fuel combustion and several production processes in primary industry have been identified. This work can be a basis for the analysis of further reduction options for a future air pollution control strategy. It can also provide essential input data for atmospheric dispersion modelling and emission calculations of toxic substances by combining PM emission data with information on the chemical composition of emitted particles
