There is no information yet about plant species capable of accumulating many different metals/metalloids. The plants feasible for phytoremediation aims must grow fast, have high biomass, deep roots, and should accumulate and tolerate a range of toxicants in their aerial parts. In our research, greenhouse and field experiments have been performed to investigate accumulation and tolerance of not well-studied trace elements such as Br, Eu, Sc, Th (and also U) in couch grass and wheat. We compared bioaccumulation abilities of the plants with those of some other plant species grown under the same conditions. Additionally, we tested the effects of inoculation of seeds with Cellulomonas bacteria on phytoextraction of the trace elements from contaminated soils. For determination of elements, we used neutron activation analysis and ICP-MS. It was found that couch grass and wheat can grow in heavily contaminated soils and accumulate different toxic trace elements to levels that exceed physiological requirements typical for most plant species. Infection of seeds with bacteria resulted in a significant increase in the uptake of various trace elements and their translocation to upper plant parts. The use of couch grass and/or wheat, either alone or in combination with microorganisms, is a promising way to phytoextract metals/metalloids from contaminated soils.

尚无有关能够累积许多不同金属/准金属的植物物种的信息。可用于植物修复目标的植物必须生长迅速，生物量高，根深，并在其地上部分积累并耐受多种毒物。在我们的研究中，已经进行了温室和田间试验，以研究在草丛和小麦中未被充分研究的微量元素（如Br，Eu，Sc，Th（以及U））的积累和耐受性。我们将植物的生物蓄积能力与在相同条件下生长的其他一些植物物种的生物蓄积能力进行了比较。此外，我们测试了接种纤维单胞菌种子的效果细菌对受污染土壤中的微量元素进行植物提取。为了确定元素，我们使用了中子活化分析和ICP-MS。人们发现，草丛和小麦可以在污染严重的土壤中生长，并积累各种有毒的微量元素，其含量已超过大多数植物典型的生理要求。用细菌感染种子会导致对各种微量元素的吸收及其向植物上部的转移的显着增加。单独或与微生物结合使用草皮草和/或小麦是从受污染土壤中提取金属/准金属的一种有前途的方法。
