Distribution of Cadmium in European Agricultural and Grazing Land Soil

The pattern dominating the Cd maps is the southern limit of the last glaciation, as well as the distribution of clay content in the European agricultural soil. In Scandinavia, a relationship to the Caledonian structural lineaments can be recongnised in the distribution pattern ; in Eastern Europe, it is the boundary between the Paleozoic cover and the Mesozoic platform sediments that stands out. The data for the aqua regia/HNO3 extracts on the maps establish the natural geochemical background of Cd concentrations in European agricultural and grazing land soil ; they demonstrate the existence of two major natural background regimes, a northern and the southern European, separated by the Trans-European Suture Zone. Most of the Cd anomalies in European agricultural and grazing land soil can be linked to geological (parent material and minerallisation) sources. In several cases, the natural anomaly pattern is overprinted by anthropogenic emissions from old mining, and the ore processing and metal industries in the same region. For a more discrete separation of geogenic and anthropogenic Cd anomalous contents, a more detailed geochemical mapping or a multivariate statistical data anlysis would be needed. Only a few Cd anomalies could be attributed to mainly anthropogenic sources, such as urbanisation and the use of fertilisers. The Cd distribution pattern of MMI® extracts shows a zone of relatively high vales throughout central Europe, which can be linked to agricultural land use (fertiliseres).
