The mercury (Hg) concentrations were evaluated in soils and perennial plants from four districts of Baia Mare city, a historical mining and ore processing center from NW Romania. The results showed that in 24% of the analysed soil samples the mercury concentrations exceeded the guideline value of 1.0 mg kg'1, established by the Romanian Legislation, while the median concentration was 0.70 mg kg'1, bellow the guideline values, but higher than the normal values for soil and the mean or median concentration in soils from other cities all over the world. In the perennial plants, the median concentration was 0.22 mg kg'1, value that exceed the maximum level of Hg (0.10 mg kg'1) established by European Directive 2002/32/EC for animal feed in order to prevent its transfer and further accumulation in the higher levels of food chain. Poor correlations were found between Hg and other elements such as As, Cd, Cu, Pb and Zn known as pollutants resulted from non-ferrous smelting activities, probably due to the different physicochemical properties of Hg that lead to a different dispersion patter compared to other metals emitted by the two smelters.
