The presented study was focused on soils developed from fluvioglacial sands from the Puszcza Borecka forest complex. The mobility of chromium, nickel and vanadium was evaluated with regard to litho- and pedogenic factors. The aim of the study was to determine with which soil constituents fractions of heavy metals are bound with particular attention drawn on the mobile fractions (F1+F2). Heavy metal fractions in the soils were determined using the sequential extraction method of Tessier et al. The purpose of sequential extraction methods to soil samples provides relevant information about possible toxicity when they are discharged into the soil environment. Chromium, nickel, and vanadium occurred predominantly in the fraction bound with iron and manganese oxides and in the residual fraction, thus showed low mobility. With regard to mobility, the elements studied can be arranged as follows: V<Cr<Ni. The content of the mobile fractions depended on the soil texture. The influence of the rusting process on the distribution of the bioavailable fractions was observed in the soil profiles.
本研究集中于波美拉尼亚森林复合体的河流冰川砂发育的土壤。考虑到岩性和土壤成因因素,评估了铬、镍和钒的迁移性。本研究的目的是确定重金属与土壤成分的结合情况,特别关注可移动的部分(F1+F2)。使用 Tessier 等人的连续提取方法测定土壤中的重金属。连续提取方法的目的是为了提供有关土壤样品在排入土壤环境时可能毒性的相关信息。铬、镍和钒主要存在于与铁和锰氧化物结合的部分和残余部分,因此迁移性较低。就迁移性而言,研究的元素可按以下顺序排列:V<Cr<Ni。可移动部分的含量取决于土壤质地。在土壤剖面中观察到生锈过程对生物有效部分分布的影响。
