Fig. 2. The factory premises of BSL Werk Schkopau located near Halle/Saale, Germany. The entire
BSL Werk Schkopau covers an area of approximately 4 km 2 with an adjacent waste disposal in the
north-west of an additional size of 3 km 2
also be of interest with regard to different behaviours in the atmosphere, i.e.
gaseous HgCl2 and dimethylmercury, were not separately measured during the
field experiments. However, both species contributed to the TGM value which
was measured.
The intention of the in-situ measurements was to obtain information
concerning the horizontal distribution of gaseous mercury 0.5 m above ground
level. The area within a maximum distance of 5000 m from the sources was of
main interest. All detections were made within the expected plume of mercury
which was developed in the main direction of the wind shaped by the wind shear
and temperature profiles.
In order to obtain data for different atmospheric conditions during the
sampling period from December 1993 to June 1994, the measurements were
carried out on an event basis. The reason for this was to include the influence of
seasonal and temperature-related variations. Table 1 shows typical measurements
