Environmental-geochemical mapping program in the Slovak Republic

The paper presents a review of environmental-geochemical mapping of the Slo vak Republic. The project 'Geochemical Atlas of the Slovak Republic' (imple mented at the beginning of 1991), comprises completed (or nearly completed) geochemical atlases of groundwater, soils, stream sediments, forest biomas s, rocks and natural radioactivity of the Slovak Republic at a scale of 1:1 ,000,000. These serve as background for environmental-geochemical mapping i n selected regions at a scale of 1:50,000 which is now in progress (for wat er, soil, sediment and rock). In order to allow for compatibility between i ndividual regions, methodological guidelines were developed (as required fo r all studies funded by the Ministry of the Environment of the Slovak Repub lic).
