Emissions of Heavy Metals and Lindane into River Basins of Germany

With the completion of this project a quantification of heavy metal and lindane emissions into surface waters is provided for the first time for Germany and for the years 1985, 1995 and 2000. Using the statistical and geographical basic data integrated in the MONERIS model system (Modelling Nutrient Emissions in River Systems), substance inputs were calculated by methods analogous to those used for the balancing of the nutrients. They were differentiated according to their sources and pathways and documented for the specific pathways. For this purpose, extensive studies and model adaptations were required to provide a most realistic representation of substance specific transport and retention processes. All quantification approaches as well as the applied basic data were thoroughly documented. As a result an accessible overall model, always open to new perceptions, is now available.
