The study area covers approximately 1000 km(2) in the south of Central Saxony, and 138 samples from 46 sampling sites were examined. Ge and REEs in soils were partitioned by a sequential extraction procedure into mobile/exchangeable (Fraction 1), acid soluble (Fraction 2), bound to organic matter (Fraction 3), amorphous Fe/Mn-oxyhydroxides (Fraction 4), crystalline Fe/Mn-oxides (Fraction 5) and residual fractions (Fraction 6). Total concentrations of Ge and REEs in soil varied considerably ranging from 1.0 mu g g(-1) to 43 mu g g(-1) for Ge (mean 1.9 mu g g(-1)) and 97 mu g g(-1) to 402 mu g g(-1) (mean 168 mu g g(-1)) for total REE contents, accounting for 17% and 14% to the investigated light REEs La and Nd, respectively and 2.8% and 1.5% to the investigated heavy REEs Gd and Er, respectively. Elements in potentially plant available fractions represented 8% of total Ge and 30% of total REEs, respectively. Soils on moist grasslands characterized as acidic fluvisols and gleysols with high organic matter content contained significantly higher total concentrations of Ge and REEs and higher concentrations of Ge and REEs in the potentially plant available Fractions 1-3 compared to soils of mesic grassland and arable land. Grass species accumulated significantly higher concentrations of Ge than herb species. Highest concentrations of Ge were measured in plant species growing on moist grassland (Phalaris arundinacea: 449 ng g(-1)), while there were no significant differences with regard to the concentrations of REEs in plants among the different land use types. The results of this study indicate that moist grasslands may act as sinks for Ge and REEs. In these soils high amounts of soil organic matter and low pH may foster the retention of labile forms, increasing the pool of Ge and REEs accessible for phytoextraction. However, the species-specific processes involved during the uptake of REEs need to be understood in order to optimize phytomining techniques. (C) 2017 Elsevier B.V. All rights reserved.

In total, 12 sampling sites with different composition of plant species were selected. Soil samples from a depth of 10 cm and samples of plant material were taken at each of these sites. The soil samples were analyzed for total concentrations of elements, pH (H2O) and element concentrations in four operationally defined soil fractions. Element concentrations in soil extracts and plant digests were measured by ICP-MS. Our results show that besides high concentrations of toxic trace elements, the substrates are characterized by high concentrations of Ge (up to 8 mg kg-1), but only moderate concentrations of REEs. The pH of the substrates correlated significantly positively with the total concentrations of all investigated elements, except of As and Pb. Potentially plant available concentrations decreased in the order Cd > Zn > As > Pb > >REEs > Ge. However, highest concentrations of Ge were found in Phragmites australis (0.63 mg kg-1 Ge) and Phalaris arundinacea (0.57 mg kg-1 Ge), whereas Populus tremula, Tanacetum vulgare, Lotus corniculatus and Agrostis capillaris showed high concentrations of toxic trace elements and rare earth elements URL https://www.researchgate.net/publication/315834363_Concentration_and_bioavailability_of_toxic_trace_elements_germanium_and_rare_earth_elements_in_contaminated_areas_of_the_Davidschacht_dump-field_in_Freiberg_Saxony Kategória publikačnej činnosti ADE Číslo archívnej kópie 39104 Kategória ohlasu SOBOLEV, O. - GUTYJ, B. - SOBOLIEVA, S. - BORSHCH, O.
