Contents of Cd, Pb, Cr and Ni were determinated in the soils, under spruce and Scotch pine cover on the Mt Goc, by applying the method of micro-site indicator values. These researches were determinated origin of heavy metals in these soils. Soil samples were taken according to the micro-site indicator values method, and samples were prepared according to the UNEP - UN/ECE (1994) rules. The contents of the total Cd, Pb, Cr and Ni in studied soils analysed were determined by AAS method using the "Varian - AA - 10" apparatus. Measured concentrations, on micro and macro- site were compared with critical concentrations for the organic layer and for mineral soil. The origin was evaluated on the compared concentrations of heavy metals on micro- and macro- site, and their distribution in soil profile.
