Presentation is focused on the main results of the pilot urban soils research in Slovakia (Urban soils as Environmental factor of living quality in cities (city Bratislava)-APVT-27-022 602).Map of Urban Soils of Bratislava in the scale 1 ∶ 35 000 is presenting as one ofthe outputs.As the main information sources were used:Data base of recognition and detailed soil survey of pedo-urban ecosystems of Bratislava city with respecting spatial diversity of urbanized territory and highlighting areas with most soil environmental significance,ortho-photo maps scanned in July 2002 have been used as a base of delineation (scale 1∶5,000,digitalization into scale 1∶25,000) Soil description field book:urban pedotope description,characteristics and classification of13 selected representative soil profiles following these properties:texture,pH,CaCO3 content [%],Cox content [%],humus content [%],Nt content [mg·kg-1],P content [mg·kg-1],in some cases heavy metals analyses (Cd,As,Pb,Ni,Cr,Hg,) and organic pollutants analyses (PAH,PBC,NEL).Soil profiles were classified according to Morphogenetic Soil classification system of Slovalia (2000) incl.signature of diagnostic horizons.Sampling and analyses of surface soil contamination on risk elements (heavy metals:Cd,As,Pb,Ni,Cr,Hg) from 20 potentially most loaded urban location in the city).Data base of Soil Science and Conservation Research Institute sources:basic soil maps of the county Bratislava,in the scale 1∶50,000 from the General Soil Survey of Agricultural Soils (GSSAS),maps of texture,skeleton and moisture,maps of parent substrate,own soil survey in cities,mainly in non-mapped areas.Data base stored in Atelier for Environment city Bratislava:sources of air pollution,registered waste stock-piles,old environmental load situation,etc.Finish works have been elaborated in ArcGis Desktop (ESRI firm) in programme ArcMap 9.1.
