Studies on the abundance of trace metals in submerged reed were performed in various aquatic ecosystems of Greece and Poland in the period from 2005 to 2006. The analyzed metals were Cd, Pb, Zn, Cr, Ni, Cu, Co, Fe, Mn, K, Na, Mg, and Ca. The relation between the concentrations of metals and water characteristics (salinity, temperature, etc.) was explored by the use of Principal Component Analysis. The results showed that the temperature facilitates accumulation of Cd, Pb, and Co. Common reed grown in salty reservoirs contained more Na and Mg, which are present in water in the form of NaCl and MgCl2. Water temperature plays no important role in accumulation of Ni and Cr in reed. Differences in the content of Cr and Ni in underwater parts of reed were caused by individual characteristics of the sampling point (i.e. intensity of recreation) and increased uptake in growing season. An independence of Cr and Ni concentration in reed on integrated water salinity was confirmed. Pools of Fe and Mn in Phragmites australis were similar in both countries, but reed collected in several locations in Vistula Lagoon allocated more Fe and Mn. Large accumulation of Cu in stems of reed was discovered in highly anthropopressed melioration ditches.
