Özet

The effect of wet ashing, dry ashing and microwave procedure for the determination of trace metal levels was investigated in house dust, tobacco and tea samples by atomic absorption spectrometry. The study of sample preparation procedures showed that the microwave method was the best. The recovery of trace metals was very good and precision and accuracy were compatible with standard reference material. The relative standard deviations for all measured metal concentrations were lower than 10%. The digestions of HNO3/H2SO4/HClO4 (4:1:1) mixture for house dust, HNO3/HSO4/H2O2 (2:2:2) mixture for tea and HNO3/H2O2 (4:2) mixture for tobacco were very efficient.
