Data on the concentration of fractions and the total content of chemical elements in catenae within a small catchment area in the Trans Urals, Russia

Abstract

Research on migration of chemical elements (ChEs) in soils is important for the understanding of geochemical processes in polluted and undisturbed landscapes. In this article, we report original data on Anthric Chernozems and Anthric Planosols within a small gully's catchment area in the Trans Urals (Russia). Mean total concentrations of 24 ChEs and content of mobile fractions (F1 – exchangeable, F2 – bound within organo-mineral complexes and F3 – bound with Fe and Mn hydroxides) of 61 ChEs including macro elements (Al, Ca, Fe, K, Mg, Mn, Na, P, Ti, S, Si), heavy metals (Ba, Co, Cr, Cu, Ni, Pb, Rb, Sr, Th, U, V, Zn), trace elements (Ag, As, B, Be, Bi, Br, Cd, Cs, Ge, Hf, Li, Mo, Nb, Pd, Sb, Sc, Se, Sn, Ta, Te, Tl, W, Zr) and rare earth elements (Ce, Er, Eu, Gd, La, Lu, Nd, Pr, Sm, Tb, Tm, Dy, Ho, Y, Yb) are determined from in a total of 60 samples from topsoil and subsoil of Anthric Chernozems and Anthric Planosols. The data obtained also include pH-value, total organic carbon content (TOC), seven particle-size classes (<2, 2–6.3, 6.3–20, 20–63, 63–200, 200–630 and 630–2000 μm), electrical conductivity and chemical composition (cations and anions) of water extracts as well as soil mineralogical composition.

Vertical And Spatial Distribution Of Major And Trace Elements In Soil Catena At The Central Forest State Nature Biosphere Reserve (Se Valdai Hills, Russia)

“…the ratio of the total contents of HMMs in soils and their concentrations in the upper part of the continental Earth's crust (Rudnick and Gao 2003), and concentration coefficients (Cc), i.e. comparisons of the contents of mobile (F1, F2, F3) fractions of HMMs in soils with average values reported for the A-horizon of the Retisols at the East European Plain and the Albic Luvisols of Western Siberia (Samonova et al 2018, Semenkov et al 2019Semenkov et al 2016). As a Cc ranged from 0.5 to 2.0, the content of elements was similar with the standards.…”

“…The ratio of F1+F2+F3 to the total content reflects the mobility of HMMs in soils (Yutong et al 2016). The F-analysis is a modern approach to studying the migration of chemical elements in soils and landscapes (Bolan et al 2014;Li et al 2019;Reimann et al 2018;Sosorova et al 2012;Gronflaten, Steinnes 2005;Semenkov et al 2016Semenkov et al , 2019Huang and Matzner 2007;Sosorova et al 2012;Motuzova 2014;Popova 2010;Kosheleva et al 2002Kosheleva et al , 2015.…”

“…F1 fractions of Ni, Pb, As, Cu (Huang and Matzner 2007;Sosorova et al 2012;Motuzova 2014), F2 fractions of Zn (Popova 2010) accumulate at the sorption geochemical barrier in the A-and Bt-horizons and is depleted in the E-horizon. F3 fractions of Fe, Co, Cr, Cu (Tolpeshta and Sokolova 2010;Semenkov et al 2019;Adriano 2001) are removed from the topsoil. Their content increases monotonously in the subsoil horizons.…”

“…Few studies of spatial differentiation of element mobile fractions in background taiga landscapes show that F1 fractions of Cu, Zn, Mn, Co and F2 fractions of Cu, Co accumulate in the upper parts of the catenas (Semenkov et al 2019;Semenkov et al 2016). The content of F1 fractions of Ni Co, Fe, F2 fractions of Fe, Zn, Ni, Sr, Pb and F3 fractions of Fe, Mn, Cr и Ni increases down the catena (Kosheleva et al 2002;Semenkov et al 2019;Semenkov et al 2016).…”

Dataset of trace elements concentrations in snow samples collected in Jelgava City (Latvia) in December 2020

“… The collected data can be used to evaluate point-source and nonpoint-source, pollution impact on air quality. The multidisciplinary research of dust and chemical elements long distance transport in future will be possible if data in this article are included in models with point source pollution [1] and distribution of chemical elements in catchment areas [2] . …”
