Copper (Cu) is one of the most pollutants that impact the soil of urban environment. Urbanization in Yogyakarta city with its human activities causes a soil contamination. The objective of this study was to determine the geochemical fraction of copper and the risk assessment in urban territory. The study area, Kotagede district, is located in the southeastern part of Yogyakarta Special Province, and it is the oldest urban area. The soil sampling was drilled by hand auger until 7 meters and sampled for each 1 m depth from the surface. Six steps of sequential extraction procedures were carried out to assess the geochemical fraction of copper and risk assessment of copper. The highest amount of copper was found in amorphous iron oxide with the average of 81.72%. Exchangeable of copper in the geochemical fraction was shown in a negligible amount. Because of high concentration copper in amorphous iron oxide fraction, copper seems to occur as poor mobilization, bioavailability, and low-risk assessment in the study area. [ABSTRACT FROM AUTHOR]
