Occurrence and enrichment sources of cobalt, chromium, and nickel in soils of Mitrovica Region, Republic of Kosovo
2021
The main purpose of this study is to determine the differences between anthropogenic sources and lithogenic sources of the content of certain potentially toxic elements in the region of Mitrovica, Republic of Kosovo. For that purpose, the results of a study on the spatial distribution and enrichment of cobalt, chromium and nickel in surface soil from Mitrovica and its environ, are reported. The average content of Co, Cr and Ni in soil amounts to 22 mg kg-1, 60 mg kg-1 and 96 mg kg-1, respectively. Spatial distribution maps of Co, Cr and Ni shows their predominance in the area of Triassic serpentinites on the North-eastern and Western parts of study area. The lowest contents are found on the outcropping of Miocene latites, quartz-latites and pyroclastites. It has been established that the increased content of Co, Cr and Ni in soils from this area is of lithogenic origin. It is shown that content of Co, Cr and Ni exceeds the target Dutch value in 173 km2, 82 km2 and 256 km2 (from 302 km2 of the study area), respectively, while the content of Cr and Ni exceeds the action Dutch value in 17 km2 and 63 km2, respectively.
