Concentration of the elements Mn, Fe, Cr, Ni, Co, As, Cd, Pb, Zn and Cu in water and plant samples were measured by inductively coupled plasma mass spectrometry (ICP-MS) (ELAN 5000, Perkin-Elmer). The instrument was calibrated by external standards of multi-element solutions for a range of 1-10 p-g/kg for water samples and 0.5-20 (xg/kg for plant material. Digested plant samples were diluted accordingly. Matrix effects and spectral interference were compensated by addition of internal standards ( Rh and Th).
