Abstract The interferences encountered in trace metal analysis of plant media by ET-AAS are described. The atomization of Cd, Cr and Ni are weakly perturbed by the plant matrix elements and no corrections have been investigated. For Pb, T1 and Sb a drastic slope reduction of the working curve is observed, which drastically reduces sensitivity. These perturbations are minimized by the L'vov platform technology, the efficiency of which has been tested with four commercially available ET-AAS systems. Matrix modification by ascorbic acid may be also efficient.
