- Abstract
The aim of study in 2007-2009 were investigated the relationship of soil-plant-metal content in dominant plants and soils on the Tisza river and flood-basin. Between 2007-2009 in soils of flood-basin 20.6-24.6 mg/kg Cr, 0.40- 1.15 mg/kg Cd, 28.4-66.7 mg/kg Cu, and 89.7-180.3 mg/kg Zn was found. The metal concentration range in roots of dominant plant species (Atremisia vulgaris L., Rubus caesius, Solidago canadensis) found in floodplains were 0.9-4.7 for Cr, 1.6-8.1 for Cd, 22.7-31.5 for Cu, and 106-186 for Zn in mg/kg. The leaves contained 0.7-3.9 Cr, 1.2-1.6 Cd, 0.6-42.8 Cu, and Zn 24.9-203.5 in mg/kg. Our study showed, that the high level of metals as soil contaminations and the high plants metal contents harmful in river compartment. Dominant bacteria were mostly Gram-negative micro-organisms: Pseudomonas, Enterobacter, Bacillus and Coryneform genera. The metal contents and number of bacteria showed positive correlation colonizing the leaves surfaces of plants.
