Russian soil quality standards (maximum permissible concentrations) exist only for Mn, Pb and V out of the many heavy metals (HMs) indicative of soil pollution resulting from hydrocarbon mining. This paper presents a comparative analysis of the total content of Ba, Cr, Cu, Ni and Zn as well as Mn, Pb and V in background soils of Western Siberia (Russia) in relation to the wider range of available internationally recognised assessment criteria. The criteria used include the increase in abundance of elements relatively to the upper part of the continental earth's crust, their levels in background soils of other countries and their threshold concentration values for soils of residential and/or agricultural areas in soil quality standards (SQSs) of Netherlands, Germany, the USA and Canada. Specified countries have similar soils and background concentrations of HMs and well-developed methodologies for soil quality assessment. It is concluded that Cu, Ni and Zn levels in West-Siberian background soils are harmless for an ecosystem and human health, while Ba, Cr, Mn, Pb and V concentrations in some of the soils studied are above threshold values (ThVs) and, therefore, require special attention through further assessment. The studied Retisols, Phaeozems and Chernozems of Western Siberia are characterized by the following range of mean concentrations (mg kg−1) of HMs in topsoil: Ba 373–1360, Cr 5–212, Cu 5–100, Mn 50–1800, Ni 7–100, Pb 5–35, V 5–180, and Zn 10–135. In preliminary assessment of contaminated soils within a coniferous forest and forest-steppe ecosystems of Western Siberia, it is most suitable to use the following national ThVs for HMs (mg kg−1): Canadian Pb (45), German Ni (140) and Cr (400) and Dutch Cu (96) and, considering the local geochemical background (especially for the folic horizon of Retisols), it is also appropriate to use Russian Mn (1500), Canadian Zn (200) and Dutch Ba (890). An eluvial pattern of vertical differentiation is typical for total Cr, Cu, Ni, Pb, Zn in Retisols, Ni and Pb in Phaeozems and Cr, Ni and Pb in Chernozems. In topsoil of background landscapes at Western Siberia, total Mn (in all soils studied), Cu (in Phaeozems), Zn (in Phaeozems and Chernozems), as well as mobile Mn (in Retisols and Phaeozems), Ni (in Retisols) and Zn (in Phaeozems) accumulates.

西伯利亚西部土壤中的重金属含量与国际土壤质量标准的关系

俄罗斯的土壤质量标准(最大允许浓度)仅针对表示重金属开采造成的土壤污染的许多重金属(HM)中的Mn,Pb和V才存在。本文针对西伯​​利亚(俄罗斯)背景土壤中Ba,Cr,Cu,Ni和Zn以及Mn,Pb和V的总含量进行了比较分析,并与更广泛的国际公认评估标准相关。使用的标准包括相对于大陆地壳上部而言元素的丰度增加,其他国家背景土壤中元素的含量以及土壤质量标准(SQS)中居住和/或农业区域土壤的阈值浓度值荷兰,德国,美国和加拿大。指定的国家具有类似的土壤和重金属的背景浓度,以及完善的土壤质量评估方法。结论是,西西伯利亚背景土壤中的铜,镍和锌水平对生态系统和人类健康无害,而某些研究过的土壤中的钡,铬,锰,铅和钒的浓度高于阈值(ThVs)和因此,需要通过进一步评估来特别注意。西伯利亚西部研究的网纹岩,辉石和黑钙土的特征在于以下平均浓度范围 在某些研究过的土壤中,铅和钒的浓度高于阈值(ThVs),因此,需要通过进一步评估来特别注意。西伯利亚西部研究的网纹岩,辉石和黑钙土的特征在于以下平均浓度范围 在某些研究过的土壤中,铅和钒的浓度高于阈值(ThVs),因此,需要通过进一步评估来特别注意。西伯利亚西部研究的网纹岩,辉石和黑钙土的特征在于以下平均浓度范围表土中HM的-1):Ba 373–1360,Cr 5–212,Cu 5–100,Mn 50–1800,Ni 7–100,Pb 5–35,V 5–180和Zn 10–135。在对西西伯利亚的针叶林和森林草原生态系统内的污染土壤进行初步评估时,最适合对HMs使用以下国家ThV(mg kg -1):加拿大的Pb(45),德国的Ni(140)和Cr(400)和荷兰的Cu(96),并且考虑到当地的地球化学背景(尤其是对于Retisols的叶面),也宜使用俄罗斯Mn( 1500),加拿大锌(200)和荷兰钡(890)。垂直分异的坡向模式是典型的,其中网状土壤中的总Cr,Cu,Ni,Pb,Zn,火药中的Ni和Pb以及黑钙土中的Cr,Ni和Pb。在西伯利亚西部背景景观的表层土壤中,总锰(在所有研究过的土壤中),铜(在辉石中),锌(在辉石和黑钙石中),以及移动态锰(在网状酚和草辉中),镍(在网状溶胶中)和锌(在辉菌中)积累。
