摘要

在HM分数组成和数理统计研究的基础上，对布拉戈维申斯克土壤中重金属的迁移程度进行了综合评价。结果表明，Cu、Cr、Ni、Co和Pb主要富集在残余组分中，Mn、Cd和Zn主要富集在Fe和Mn的氢氧化物和残余组分。在增加Zn污染物的工艺添加下，Pb因比吸收不稳定而固定在土壤中，Cd因比吸收而固定在氢氧化物部分中。Cu与有机馏分结合，Cr、Co和Ni与有机馏分和氢氧化物馏分结合。与背景土壤相比，城市土壤中Zn、Pb、Ni、Cu、Cr和Cd的迁移潜力增加。在所研究的元素中，Zn、Mn和Cd的潜在迁移率对应于高水平的危险，构成了最大的危险。

Complex analysis of heavy metals mobility in the soils of the border town of Blagoveshchensk (Far East, Russia)

A comprehensive assessment of the degree of heavy metals mobility in the soils of Blagoveshchensk was carried out, based on research on HM fractional composition and mathematical statistics. It was shown that the majority of Cu, Cr, Ni, Co and Pb accumulates in residual fraction components and that Mn, Cd and Zn accumulate in Fe- and Mn-hydroxides and the residual fraction. Under the increased technogenic addition of Zn contaminants, Pb was fixed in soil due to unstable specific absorption, Cd due to specific absorption and in hydroxide fraction. Cu was bound to an organic fraction, and Cr, Co and Ni to organic and hydroxide fractions. In urban soils compared to background soil, there was increased potential for the mobility of Zn, Pb, Ni, Cu, Cr and Cd. Among the elements studied, Zn, Mn and Cd, whose potential mobility corresponds to a high level of danger, posed the greatest danger.

期刊介绍： IJEP provides an international forum in the field of environment and pollution and addresses early and medium-term challenges involving scientific prediction, modelling and assessment. It focuses on ground-breaking research in the science of environmental pollution, at the early scientific stage. It is one of three key journals which together offer complete coverage of environmental issues: IJETM focuses on technical/engineering, policy and management solutions for environmental problems, and IJGEnvI focuses on future, longer-term environmental scenarios, ecological economics, climate change and biodiversity.
