Mobile Metal Ion analysis of European agricultural soils : bioavailability, weathering, geogenic patterns and antrhropogenic anomalies
Two thousand one hundred and eight agricultural soils (0-20 cm depth) collected at a density of one sample per 2500 km2 under the auspices of the Geochemical Mapping of Agricultural Soils (GEMAS) project over most of the European continet have been analysed using the Mobile Metal Ion (MMI (R)) partial extraction techique with ICP-MS finish. For a number of elements, notably Ce, Ni and Ca, coherent geogenic patterns have been observed which relate to underlying lithology. For Fe and Al, coherent patterns are also observed but the effects of weathering are evident, and provide a mechanism to explain the acidity of soils in high rainfall areas. Individual anomalies, many related to antrhopogenic activity (mining, metallurga, agriculture) have been observed for Ag, Au, Cu, Pb, Cd and Zn. Comparison of the results with aquy regia digestion and the equivalent National Geochemistry Survey of Australia (NGSA) provides insights into weathering processes and the concept of bioavailability.
