Method

Activity data

The yearly production figures were taken from the annual statistical report of the German association for non-ferrous metals [Lit. 1].

Emission factors

The emission factors are either default values according to the 2019 EMEP/EEA air pollutant emission inventory guidebook [Lit. 2] or determined in several research projects. For heavy metals (HM), the applied emission factors are derived from a research project [Lit. 3]. All emission factors have a decreasing trend except SOx that is supposed to be constant.

Pb 4.506295 g/t

PCB 2.1 mg/t
PCDD/F 0.34 µg/t

Recalculations

With activity data and emission factors remaining unrevised, no recalculations were carried out compared to Submission 2022.

Planned improvements

The emission factor for PCB is still orientated to old emission guidebook values and seems to be to high due to legal terms. The factor will be updated in the next submission 2024.
