metadata.value: Speciation of ore and accompanying elements (Cu, Zn, Fe, Ni, Pb, Cd, Cr, V, Ba, Sr) in steppe
  soils of the Transurals (vicinity of city of Sibay, Bashkortostan) was studied with sequential
  extraction method. Attention was given to change of elements’ speciation in area affected by
  mining (Cu-Zn deposit). The results are supplemented by chemical analysis of humic acids
  (isolated by alkaline extraction) and granulometric fractions. It was revealed that the soils
  of background areas are characterized by low mobility of studied elements and a relatively
  uniform distribution over soil profile. Residual fraction percentage (fraction’s share in element’s
  total content) is the highest. Percentage of exchangeable and carbonate fractions is
  insignificant (Sr and Ba are exceptions). Percentage of fraction of crystalline Fe hydroxides,
  reduceable and oxidizable fractions varies from shares of a percent to 15 %. Cd stands out
  for a high percentage of oxidizable fraction (up to 30 % of Cd total content) and relatively
  low percentage of residual fraction (up to 50 %). Comparison of obtained results allows us
  to suggest that near objects of mining industry dust enriched with Cu, Zn, Cd, Pb and Sb
  comes to the surface. This leads to shard increase of Cu, Zn, Cd content in the upper layer of
  chernic horizon, change of these elements’ speciation and distribution among granulometric
  fractions. Increase of elements content is not only due to prevailing residual fraction; Cu, Zn,
  Cd of oxidizable fraction, reducible fraction and Fe hydroxides fraction significantly increase.
  Sharp increase of oxidizable fraction percentage (largely due to sulfides) is noted.
