Lithuania’s soil is among the cleanest in Europe2007-10-16
According to the data in the European Geochemical Atlas, Lithuanian soil is among the cleanest on the continent by levels of both heavy metals and other chemical elements. Deputy Director of the Lithuanian Geological Service under the Ministry of Environment says that in Lithuania both the upper soil layer and the subsoil contain from three to six times less plumbum than in West European countries.
The European Geochemical Atlas was compiled by geological organisations of 26 European states according to a single methodology. These include the Lithuanian Geological Service. Its specialists systematically accumulate data on the geochemical composition of the country’s soil and on its contamination with heavy metals.
The said atlas was published last year. It provides information about levels of chemical elements in the continent’s soil, the forest floor, river water, bed deposits and floodplain sediment. Those levels depend on not only natural geological, climate and hydrologic conditions, but also human activity. Comparison of element concentrations in the upper soil layer and in the subsoil enables determination of the nature of chemical anomalies. If the level is higher in the upper layer, it should then be associated with technological pollution.
The atlas contains 360 maps, which show distribution of 66 chemical elements in soil and other parameters. The materials published in its two chapters, all data from geochemical research, maps, etc. are available from the website of the Finnish Geological Service at http://www.gsf.fi/publ/foregsatlas/index.php.
