Maximum permissible concentrations for chemical elements in soils (MPCs) of Russia, Germany, Canada, the Netherlands and the USA are compared. In Russia, general sanitary, water-transferred and translocation MPCs are created; in Germany, general sanitary and translocation, and in the Netherlands, the USA and Canada, general sanitary. It is found that the Russian MPCs for total contents of chemical elements are adequate for Mn and V, American, for Co, Cu, and Pb; Dutch, for Pb and Zn; Canadian, for Ba, Co, Ni, Pb, V, and Zn, and German, for Cr, Ni, and Pb by taking into account the typical levels of elements in the background soils across the world. The methodologically closest Russian and Dutch standard rates of total contents of chemical elements are compared in this paper with the typical levels for background Retisols gleic, Phaeozems, and Chernozems in the center of Western Siberia. It is established that use of the Dutch MPCs for the soils under study gives fewer cases of false Pb pollution, but in all the soils under consideration the Dutch MPCs for Ba is exceeded. False pollution by total Zn is observed in the top-soil; by Cr, Cu and V, in subsoil horizons of Retisols gleic as well as by Cr, Ni and V, in most samples of Phaeozems and Chernozems. It is concluded that for the soils under consideration the utilization of Russian MPCs gives fewer cases of false pollution by V. But in the background Retisols gleic, Russian MPCs for Mn and Pb accumulated in the biogeochemical barrier in the top-soil horizons are exceeded. Russian MPCs for metal mobile fraction are the most correct for Co, Cr, Cu, Ni and Pb. The MPCs for mobile fraction of biogenic Mn and Zn are underestimated. Background levels (mg/kg in subindex) of total concentration (mobile fraction extracted by acetate-ammonium buffer) are proposed for Ba 404–515 , Co 12–19(0.001–0.23) , Cr 143–188(0.001–0.72) , Cu 32–41(0.01–0.72) , Mn 423–874(0.09–64) , Ni 30–62(0.003–1.3) , Pb 18–27(0.003–0.87) , V 112–170 иZn 55–104(0.004–0.42) in Retisols gleic on Tobol Upland, Phaeozems on Ishym Upland, and Chernozems in the Trans-Ural region.

土壤中化学元素的标准含量:西西伯利亚的国际经验和使用

比较了俄罗斯、德国、加拿大、荷兰和美国土壤中化学元素 (MPC) 的最大允许浓度。在俄罗斯,创建了一般卫生、输水和易位 MPC;在德国,一般卫生和易位,在荷兰,美国和加拿大,一般卫生。发现俄罗斯化学元素总含量的 MPCs 对 Mn 和 V 是足够的,美国对 Co、Cu 和 Pb 是足够的;荷兰语,用于 Pb 和 Zn;加拿大,Ba、Co、Ni、Pb、V 和 Zn;德国,Cr、Ni 和 Pb,考虑到世界各地背景土壤中元素的典型水平。本文将化学元素总含量的方法学上最接近的俄罗斯和荷兰标准比率与背景 Retisols gleic、Phaeozems、和西西伯利亚中部的黑钙土。已经确定,在所研究的土壤中使用荷兰 MPC 会减少假铅污染的情况,但在所有考虑的土壤中,Ba 的荷兰 MPC 都被超过了。在表层土壤中观察到总锌的虚假污染;Cr、Cu 和 V,在 Retisols gleic 的底土层中,以及 Cr、Ni 和 V,在大多数 Phaeozems 和 Chernozems 样品中。得出的结论是,对于所考虑的土壤,俄罗斯 MPC 的利用提供了较少的 V 虚假污染案例。但在背景 Retisols gleic 中,俄罗斯 MPC 在表层土壤生物地球化学屏障中积累的 Mn 和 Pb 被超过。俄罗斯金属流动组分 MPC 对 Co、Cr、Cu、Ni 和 Pb 最正确。生物源锰和锌的移动部分的 MPC 被低估了。
