Method

Activity data

The yearly production figures were taken from the annual statistical report of the German association for non-ferrous metals [Lit. 1].
In 2022 the primary and secondary lead production amounted to 229 kt.

Emission factors

The emission factor for SOx is a tier 1 default value according to the EMEP/EEA air pollutant emission inventory guidebook 2023 [Lit. 2] and is supposed to be constant. All other emission factors are tier 2 level factors, have a decreasing trend and were determined in research projects. For heavy metals (HM), the applied emission factors are derived from a research project [Lit. 3].

Table 1: emission factors applied for primary and secondary lead production (3 digits rounded off)

EF (primary) EF (secondary) Unit
SO2 2.05 kg/t
PM2.5 17.5 g/t
PM10 21.3 g/t
TSP 25 g/t
As 49.213 41.179 mg/t
Cd 62.448 19.767 mg/t
Cu 162.663 mg/t
Hg 0.3 0.325 g/t
Pb 6.028 4.506 g/t
Zn 664 50 mg/t
PCB 2.1 mg/t
PCDD/F 0.34 µg/t

Uncertainties

The uncertainties for the production amounts are 5% and for the emission factors not more than 300%. Only for dioxines the upper bond uncertainty is about 900%.

Recalculations

With activity data and emission factors remaining unrevised, no recalculations were carried out compared to the previous submission.

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 2025.
