Two used digestion procedures: microwave aqua regia and microwave aqua regia plus HF, were compared for digestion of 2 standard references material and 36 surface and burial sediments within an industrial area in Pandevo. Samples collected at 20 locations within petrochemical and at 16 locations in near by non-petrochemical area and were extracted and analyzed by ICP/OES. Ten elements such as: Ba, Cd, Cu, Cr, Mn, Fe, Ni, Pb, V and Zn were analyzed. Accuracy was also acceptable for certified metals in aqua regia plus HF being 78-110 % except for Pb iii BCR 143 R standard where it was 172 %. Accuracy for certificated metals in aqua regia digestion was acceptable by being 80-113%. Precision for aqua regia with HF were less than 5 %, while for aqua regia was little bit higher but less than 10 %, except for V where it was 12 % and for Cd it was 28 %. The aqua regia with HF has slightly better precision than the simple aqua regia.
