 In the German cement industry, dust separated from clinker burning exhaust gas is returned to the burning process. As a result, there is no need to take account of significant losses of particles via the exhaust-gas pathway. - On the other hand, particulate matter emissions occur during clinker grinding. In the German cement industry, dust separated from clinker burning exhaust gas is returned to the burning process.

-EF for Hg is based on aggregated figures for individual plants of PRTR-reporting. The trend estimation is based on an expert judgement and derived from TSP trend.+EF for Hg is good to aggregated figures for individual plants of PRTR-reporting.

-With **activity data** and **emission factors** remaining unrevised, no recalculations should be neccessary compared to last year's submission. +Recalculations were necessary due to updated emission factors for all years. The significant changes can be shown as an absolute difference over time as follows:

 But since data for PAH 1-4 in NFR-Tables only shows the sum of the available four PAHs, only BaP and the value for PAH 1-4 have decreased strongly. Please see the EF chapter, too. But since data for PAH 1-4 in NFR-Tables only shows the sum of the available four PAHs, only BaP and the value for PAH 1-4 have decreased strongly.
