Dispersion Modelling
The local atmospheric transport of gaseous mercury originating from emissions
at the BSL Werk Schkopau was calculated for distances of a maximum of 10 km.
A numerical model for simulating transport from individual point sources was
applied. Earlier results of this transport model (Eppel et al. 1991) compared well
with measurements within a spatial range of a maximum of 100 km.
