The content of nutrients and heavy metals was indicated in different parts of Typha angustifolia and Typha latifolia, collected in lakes in western Poland. Three groups of metals were indicated, depending on the place of their accumulation. The cattail species studied differed significantly with their Cu, Pb, and Cd content, but were characterized by the same accumulation pattern in the leaves: Mn > Fe > Zn > Cu > Pb > Ni > Cd, and in the rhizomes: Fe > Mn > Zn > Pb > Cu > Ni > Cd. The statistical results of this research suggest the possibility of using Typha latifolia in the biological analysis of contamination by Mn.
