GEMAS European Geochemical Data

The GEMAS dataset is based on low density geochemical sampling of agriculture (Ap) and grassland (Gr) soils across 34 European countries. Sample density covering an area of 5.6 million km2 of 1 site each, arable land (0-20 cm) and land under permanent grass cover (0-10 cm), per 2500 km2.

The Geochemical Mapping of Agricultural and Grazing Land Soil comprises more than 70 chemical elements and parameters determined on more than 4000 soil samples. The geochemistry of European agriculture and grazing soils are depicted graphically on maps of the GEMAS geochemical atlas.

In 2016 the Geological Survey of Ireland as a European partner contributes to GEMAS and EGDI (European Geological Data Infrastructure) with provision of a GIS spatial data classification and publication of WMS geochemical web mapping services to support European data interoperability of EGDI web portal.

The GIS GEMAS sample classification were constructed in ArcGIS 10.1 and the original GEMAS dataset is available as ESRI shapefile format.

Purpose

The GEMAS (geochemical regional mapping of agricultural soils and grazing land of Europe) project aims at providing harmonized geochemical data of arable land and land under permanent grass cover at the continental, European scale.

EU Soil Protection Directive (Van Camp et al., 2004; EC, 2006b), require additional knowledge about "soil quality" at the European scale. REACH specifies that industry must prove that it can produce and use its substances safely.

The GEMAS project will deliver good quality and comparable exposure data of metals in agricultural and grazing land soil; soil properties known to influence the bioavailability and toxicity of metals (and other elements) will also be determined in soil at the European scale. Sample coverage for agricultural soil (Ap-samples) and land under permanent grass cover (grazing land, Gr-samples).

Results from the GEMAS project offer a variety of applications. One of them is the establishment of a ’soil sample archive’ recording the status of European agricultural and grazing land soil in the year 2008. GEMAS data define the geochemical baseline for risk evaluation related to exposure of chemicals in agricultural soil and grazing land soil, as required by REACH regulation.

Statement

•Application of the data:

The GEMAS project started in 2008 and delivered a book publication on results in December 2013. The dataset is freely available to the general public. As key results, it was observed:

- Large differences in the concentration of chemical elements between the soil of northern and southern Europe: in the northern Europe the concentrations for many elements were 2/3 times lower than in the southern Europe soil;

- Element distributions depend on geology and climate, and anthropogenic impact is hardly detectable at the European scale;

- Risk assessment for metals like Cu have shown that few samples have such high concentrations that they pose a toxic risk for soil organisms;

- Several important trace elements show low levels over sizeable tracts of land in Europe, that trace element deficiency is clearly of concern.

Results from the GEMAS project offer a variety of applications. One of them is the establishment of a ’soil sample archive’ recording the status of European agricultural and grazing land soil in the year 2008. GEMAS data define the geochemical baseline for risk evaluation related to exposure of chemicals in agricultural soil and grazing land soil, as required by REACH regulation.

•Sources of Information:

GEMAS project, involving 33 European countries, is a cooperation project between EuroGeoSurveys through its Geochemical Expert Group, and Eurometaux, the European Association of Metals.
