Abstract

This report contains an overview of the development of aqueous point source emission factors for cadmium in the Rhine River basin in the period 1970-1988. Based on these emission factors the aqueous emissions of cadmium for different industrial activities in the basin are calculated. For some activities defining emission factors does not make sense, since their cadmium emission is determined by e.g. ore or scrap purchase policy and not by the applied process technology.

The overall cadmium emission to the Rhine and to its tributaries is compared with the point source component of in-basin cadmium monitoring data. The results show reasonable agreement. Further study is required to include hydrological characteristics in a tributary-Rhine model, in order to justify the comparison of monitoring data and emission estimates. In the table below, a summary of all the calculated point source emissions in time and per branch is given. A second table provides an overview of the development of emission factors for point source emissions in the Rhine River basin in time.
