The three heavy metals Pb, Hg and Cd were examined for the induction of meiotic abnormalities and changes in the M<SUB>2</SUB> seed storage protein banding patterns of <I>Vicia faba</I> plants. The used metal nitrate solutions induced a wide range of meiotic abnormalities. The most abundant of them were stickiness, break, lagging, bridges and disturbed phases. At the level of M<SUB>2</SUB> seed storage protein, the 3 tested metals caused changes in the protein banding patterns especially at the high molecular weight regions. The results showed that lead and mercury have more mutagenic potentialities than cadmium.
