Abstract

The ecological and toxicological assessment of the soil and plant cover of a key site in the Streletskaya Steppe in the V.V. Alekhin Central Chernozem Reserve is presented. The content of heavy metals (HMs) and radionuclides in typical chernozem is determined. The clarkes of concentration of HMs (C_c); geoaccumulation lithogeochemical indices (I_geo) for As, Cd, Co, Cs, Cu, K, Pb, Sr, Zn, ²³²Th, and ²³⁸U; and pollution indices (PI) for individual HMs in chernozem have been calculated. It is shown that the pedogeochemical background is higher in comparison with the lithosphere clarkes only for Cd and As. In may be concluded that soils are not polluted with the studied HMs, namely, As, Cd, Cu, Pb, and Zn. The content of radionuclides (⁴⁰K, ¹³⁷Cs, ²³²Th, and ²³⁸U), HMs, and potassium in various types of natural steppe vegetation has been determined. Based on the plant accumulation coefficients of HMs and radionuclides, the biophilicity of radionuclides and HMs was estimated. The transfer factors (TFs) of ¹³⁷Cs and ⁴⁰K from soil to plants have been calculated, and a comparative analysis of the bioavailability of cesium and potassium during root uptake is performed. The vertical distribution of ¹³⁷Cs and ⁴⁰K radionuclides in the root-inhabited soil layer from 0- to 20-cm-thick is studied. It is shown that ⁴⁰K is evenly distributed in the root-inhabited layer. The vertical distribution of ¹³⁷Cs in the soil profile is characterized by the shift of the maximum from a depth of 0–5 to that of 5–10-cm. Based on the data obtained, the migration coefficient of ¹³⁷Cs is calculated, taking into account the convective and diffusion components of the radionuclide translocation in typical chernozem.

对 V.V. Alekhin 中央切尔诺泽姆保护区未播种的 Streletskaya 草原的土壤-植物覆盖进行生态和毒理学评估

摘要介绍了对 V.V. Alekhin 中央切尔诺泽姆保护区 Streletskaya 草原上一个重要地点的土壤和植被进行的生态和毒理学评估。确定了典型切尔诺泽姆中重金属 (HMs) 和放射性核素的含量。计算了重金属浓度克拉克值（Cc）；砷、镉、钴、铯、铜、钾、铅、锶、锌、232Th 和 238U 的地质累积岩石地球化学指数（Igeo）；以及切尔诺泽姆中单个重金属的污染指数（PI）。结果表明，与岩石圈克拉克相比，只有镉和砷的土壤地球化学背景较高。由此可以得出结论，土壤没有受到所研究的 HMs（即砷、镉、铜、铅和锌）的污染。测定了各类天然草原植被中放射性核素（40K、137Cs、232Th 和 238U）、卤代烃和钾的含量。根据 HMs 和放射性核素的植物积累系数，估算了放射性核素和 HMs 的亲生物性。计算了 137Cs 和 40K 从土壤到植物的转移因子 (TFs)，并对铯和钾在根吸收过程中的生物利用率进行了比较分析。研究了 137Cs 和 40K 放射性核素在 0 至 20 厘米厚的根栖息土层中的垂直分布。结果表明，40K 在根栖息层中分布均匀。137Cs 在土壤剖面中的垂直分布特点是最大值从 0-5 厘米深度向 5-10 厘米深度移动。根据所获得的数据，计算了 137Cs 的迁移系数，其中考虑到了典型切尔诺泽姆中放射性核素迁移的对流和扩散部分。

期刊介绍： Eurasian Soil Science publishes original research papers on global and regional studies discussing both theoretical and experimental problems of genesis, geography, physics, chemistry, biology, fertility, management, conservation, and remediation of soils. Special sections are devoted to current news in the life of the International and Russian soil science societies and to the history of soil sciences. Since 2000, the journal Agricultural Chemistry, the English version of the journal of the Russian Academy of Sciences Agrokhimiya, has been merged into the journal Eurasian Soil Science and is no longer published as a separate title.
