 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.

 Emissions of HCB are not applicable according to a research result. The table of EF is related to two different AD sets. For purposes of the most pollutants the AD is burnt clinker. For purposes of emission estimation of PM the AD is grinded clinker (included further materials as domestic burnt clinker). NFR tables could provide only one AD (burnt clinker). Emissions of HCB are not applicable according to a research result. The table of EF is related to two different AD sets.

-With **activity data** and **emission factors** remaining unrevised, no recalculations have been carried out 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:

 +[{{:sector:ippu:mineral_industry:rekalkulation_2a1_since_1990.png|**Recalculations in NFR 2.A.1**}}]

 +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.
