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.

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.
