Analyzed land areas fall into a classic mountain areas, located about 30 km south of Sarajevo and represent individual entities that are separated by the ridge. There is the presence of different types of soils on the sails Triassic limestone's and dolomites with different depth (1 cm to 60 cm), from lithosols related to colluvial soils in karst sinkhole. They are also represented different types of soils on flysch and mealy geological substrates that have a solum depth to the 140 cm. For heavy metals dynamics analyzes, we have taken soil samples from depths up to 10 cm, using representative method. The sample was formed mixing at least 10 individual samples (one sample represents 200-400 ha) which were prepared so that they would not come into contact with metal parts. We performed laboratory analyses for available forms of Co, Zn, Cd and Pb, using Novell and Linzdey's method (1978). Total forms of Pb have been determined using extraction with 6 mol/cubic dm HNO3 on the AAS. We have obtained the presence different intervals of certain heavy metals and their correlation relations with humus and pH in soils. Also we gave the values of correlation relationships and their dynamics.
