N2 - There is no information yet about plantspecies capable of accumulating many different metals/metalloids. The plants feasible for phytoremediation aims must grow fast, have high biomass, deeproots, and should accumulate and tolerate a range oftoxicants in their aerial parts. In our research, greenhouse and field experiments have been performed toinvestigate accumulation and tolerance of not wellstudied trace elements such as Br, Eu, Sc, Th (and alsoU) in couch grass and wheat. We compared bioaccumulation abilities of the plants with those of someother plant species grown under the same conditions.Additionally, we tested the effects of inoculation ofseeds with Cellulomonas bacteria on phytoextractionof the trace elements from contaminated soils. Fordetermination of elements, we used neutron activationanalysis and ICP-MS. It was found that couch grassand wheat can grow in heavily contaminated soils andaccumulate different toxic trace elements to levels thatexceed physiological requirements typical for mostplant species. Infection of seeds with bacteria resultedin a significant increase in the uptake of various traceelements and their translocation to upper plant parts.The use of couch grass and/or wheat, either alone or incombination with microorganisms, is a promising wayto phytoextract metals/metalloids from contaminatedsoils.
