GEMAS (Geochemical Mapping of Agricultural and Grazing Land Soil in Europe) is a cooperative project between the Geochemistry Expert Group of EuroGeoSurveys and Eurometeaux. In total, more than 60 international organisations and institutions worldwide were involved in the implementation of the project. During 2008 and 2009, a total of 2219 samples of agricultural (arable land soils, 0 – 20 cm, Ap samples) and 2127 samples of grazing land (pasture land soils, 0 – 10 cm, Gr samples) soil were collected at a density of 1 site/2 500 km² each from 33 European countries, covering an area of 5,600,000 km². All samples were analysed for 52 chemical elements after an aqua regia extraction, 41 by XRF (total), TC and TOC. In addition, the agricultural soil samples were analysed for 57 elements in a mobile metal ion (MMI®) extraction and Pb isotopes. All analytical results were subject to tight external quality control procedures. The GEMAS project thus provides for the first time fully harmonised data for element concentrations and bioavailability of the elements at the continental (European) scale. The downloadable files present the areal distribution of the element contents determined by different analytical methods in the shape of colour shaded contour maps with a classification in 7 and 72 levels each.

In the Federal Republic of Germany, analyses to determine the constituents of mosses were carried out at five-year intervals from 1990 to 2005 and in 2015/16 and 2020/21. The focus was on analysing heavy metals, and from 2005/06 also nitrogen. Since 2015/16, the range of substances has been expanded to include persistent organic pollutants (POPs) and microplastics. This moss monitoring is the German contribution to the European moss monitoring programme, which is coordinated by the ‘International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops’ (ICP Vegetation) of the Geneva Convention on Long-range Transboundary Air Pollution (CLRTAP). The German Environment Agency (Umweltbundesamt - UBA) has commissioned various institutions to carry out the individual sampling campaigns and analyse the results of the investigations, including the Federal Institute for Geosciences and Natural Resources (BGR) for moss monitoring in 1995/96. The UBA has published the results of subsequent monitoring years. They are available at https://www.umweltbundesamt.de/daten/luft/bioindikation-von-luftverunreinigungen. With 1026 sites, the 1995/96 moss monitoring is, alongside the 2000 moss monitoring, the one with the greatest sample density and, with 40 analysed elements, the one with the widest range of investigations. Although the research reports completed in 1998 and 1999 (Siewers & Herpin, 1998; Siewers, Herpin & Straßburg, 1999) contained an evaluation (brief description, statistical measures, distribution maps) of all 40 elements analysed, only the data of 12 of the analysed elements have been published to date. In addition, the raw data from the laboratories available as a result of the analyses were re-evaluated in 2007. This resulted in a series of error corrections and the analysable element spectrum was extended to 42 elements. The results of this re-evaluation have also not yet been published. The additional processing of the data using modern methods has further enhanced their value. The downloads show the distribution of rubidium concentrations in four different coloured dot and colour shaded contour maps. The legends of the maps can be called up either in the unit of measurement µg/g or in a unit of measurement adapted to the content range of the element shown.

BGR conducted an airborne survey in the region of the Ahlenmoor (Lower Saxony) as part of the BGR project D-AERO-Moore. Cunducting tests of their airborne system, the BGR surveys a portion of the Ahlenmoor with the BGR airborne geophysical standard measuring system. The peatland is located about 15 km northeast of the city of Bremerhaven close to Ahlen-Falkenberg. The size of the area is about 15 km². The area was surveyed with 2 flights totalling to 105 line-km (2,899 survey points). The nominal separation of the 16 WNW-ESE lines and 2 NNE-SSW tie lines was 125 m and 2000 m, respectively. The maps display the total count, the (equivalent) content of potassium, uranium and thorium as well as the exposure rate at ground.
