Mercury levels in soil samples were determined by mineralization in aqua regia followed by cold vapour-atomic absorption spectrometry (CVAAS), and by direct determination on solid matrix by pyrolysis and preconcentration using an automatic mercury analyser AMA-254 (AMA). Hg concentration in samples were in the range of 0.05 to 17.31 mg/kg for CVAAS and of 0.050 to 20.060 mg/kg for AMA.
