The last decade of 20th century in Serbia (Yugoslavia) was marked with economy recession, war surroundings, and finally bombing in the period March-June 1999. Global increment of environmental pollution was one of the catastrophic consequences. War actions caused destroying of big oil refineries and reservoirs, chemical complexes and industrial objects. Afterwards, toxic and carcinogenic substances reached out to atmosphere, soil and hydrographic system. Also, ammunition with depleted uranium was used. Heavy metals are very dangerous, so that, in this paper are presented results of investigation of heavy metals contents in surface soil layers. Heavy metals are movable, by erosion processes, with possibility of reaching hydrographic network and water supply systems. Investigation was carried out at a few localities: Fruska Gora, Ivanovo, Goc and Crni Vrh. Total contents of heavy metals (Zn, Cu, Pb, Cd, Mn) was determined by AAS (atomic spectrophotometry), by usage "Varian-Spectra AA-10" apparatus.
