Three decomposition methods (pressurised microwave digestion, classical dry ashing and dry ashing in a mixture of oxidising gases) for predominantly plant samples, and three measurement techniques (ICP-MS, FAAS, ETAAS) for the determination of Cd, Cu, Pb and Zn were compared. As confirmed by the statistical evaluation, no significant differences between analytical methods were found.
Key words: Plant material / mineralization / ICP-MS / FAAS / ETAAS / Cd / Cu / Pb / Zn.
