“…6). Losses of REE from the parent material due to weathering has been demonstrated not only for Podzols (Vodyanitskii et al, 2010, Vodyanitskii et al, 2011 but also for other different soil types developed on various parent materials such as granodiorite, Archean granite, serpentinite, shale, etc. (Nesbitt, 1979, Marsh, 1991, Prudencio et al, 1993, Mongelli, 1993, Panahi et al, 2000, Aubert et al, 2001, Ndjigui et al, 2008, Ma et al, 2011.…”

International audienceRare earth elements (REE) total concentration and signature in soils are known to be impacted by successive soil forming processes. So it be used as probe of soil processes. However, few studies focus on their behavior in Podzols. Podzols result from the combination of two main pedogenic processes: (1) the strong weathering in the surface eluvial horizon; (2) the downward transfer of dissolved organic matter (OM) and mobile AI and Fe, and their accumulation in the illuvial horizon beneath. Iron oxides and OM are known to have strong affinities with REE, and to play an important role in transfer and immobilization of REE. In order to decipher the relative importance of Fe oxide and OM in REE fate during podzolization, and to investigate whether REE can trace Podzol formation, we study here the evolution of REE signatures along five pedons, aged from 120 to 530 years, in a Cambisol-Podzol chronosequence located in the Cox Bay of Vancouver Island. Our results show that the REE content is strongly correlated to the general loss of elements and mineral weathering. Furthermore, the accumulation of secondary OM, Al and Fe-bearing phases does not impact the REE signature of the bulk soil. Both our results and the ones available in the literature indicate that the release of REE induced by weathering and,subsequent leaching in percolating water are the main pathways determining the REE fate in Podzols. Furthermore, we show that REE can be released and mobilized in very short periods of time during podzolization (330 years). (C) 2016 Elsevier B.V. All rights reserved

“…Barium is easily released during weathering processes and then precipitated in form of carbonates and sulphates, which may also influence the obtained results. The considerable content of barium in the residual fraction and in the fraction bound to iron and manganese oxides in the analyzed soils may result from the strong binding of the element by clay minerals and iron-manganese concretions (Pasieczna, 2003;Kabata-Pendias and Pendias, 1993;Pichtel, 2000;Vodyanitskii et al, 2010), particularly in the humus-elluvial, illuvial and rusty horizons of the podzols. Strontium and barium are transported downward the soil profile or accumulated in the sub-surface soil horizons, which is reflected in the obtained results.…”

The study was aimed at determining the content, distribution and mobility of barium and strontium in various forest podzol soils. Samples with a wide range of chemical and physical properties were collected from typical uncontaminated soils of south-western Poland. The total metal content in the analyzed soils was considered as the geochemical background thanks to the natural features of the study site. Sequential chemical extraction procedure were used to provide information on the mobility and bioavailability of the studied metals in the soil. Fractions of Ba and Sr were determined using the five-step procedure of Tessier et al. (1979). The results show that heavy metals were generally represented by the exchangeable fraction (F1 barium) and the residual fraction (F5 strontium) with the average values at 53 and 69%, respectively. The mobility of barium in all soil profiles was very high, ranging within 5254% and indicating a generally high availability and mobility. Relatively very low levels of the trace elements were found in the fraction bound to organic matter (F4: 38%). Very low levels of strontium were found also in the fraction bound to carbonates (F2: 23%). Humic-eluvial, illuvial and sideric horizons were enriched in the fractions of barium and strontium bound to iron and manganese oxides (F3).

“…The total content of yttrium in analysed soils ranges from 2.25 to 27.93 mg kg -1 with a mean value of 7.05 mg kg -1 . Higher but also not exceeded Clarke values results were found by Vodyanitskii et al (2010) Vodyanitskii et al, 2011). According to Kabata-Pendias and Pendias (1993), the mean values in surface horizons are in the range 5-25 mg kg -1 and are highly dependent on the soil texture.…”

This study was conducted to investigate the chemical speciation of yttrium and scandium in selected types of soils and also determined the total content and profile distribution of those elements. The research was performed on soil samples from forest areas in Puszcza Borecka (Poland) known as a non-contaminated site. Soil samples were collected from natural brown, lessive and rusty soil profiles.The sequential extraction procedure was applied to separate fractions of scandium and yttrium according to the Tessier method. The range of total content of scandium and yttrium was respectively: 0.63-6.48 mg kg -1 and 2.25 to 27.93 mg kg -1 . Scandium and yttrium occurred predominantly in residual fraction (F5) in each genetic horizon. Also both elements occurred mainly in fraction bound to organic matter (F4). The mean percentage content of scandium measured in mobile fractions (∑F1-F2) reached about 3% (in Bbr, Bt horizons) to 14% (in Bv horizons) in relation to the total content of the element in the analysed soils. The percentage content of yttrium measured in mobile fractions reached about 4% (in A, Bv horizons) to 28% in Bt horizons in relation to the total content of the element in forest soils of Puszcza Borecka.
