Abstract

Harsh environmental conditions of the study area result in low rates of ecosystem renewal. Results of geoecological studies at the sites of searching for and extraction of fossil remains of mammoth fauna in the middle reaches of the Indigirka River are presented. During the extraction of mammoth fauna remains using hydraulic washing-out, landscape components are disrupted, followed by leaching of the bedrock into creeks and rivers, thus leading to deterioration of abiotic components of the aquatic environment. Analysis of the geoecological state of the abiotic components of the ecosystem at the study site was used to assess the effects of the extraction of mammoth tusks by hydraulic mining. The study objects are cryogenic soils, bottom sediments and surface waters of the Semyuelyakh, Tirekhtyakh, and Indigirka rivers on the middle course segment. Soil and sediment samples were used to determine pH, mobile phosphorus, and Corg. Total content of Cu, Sn, Zn, Pb, Ge, B, Cr, Ni, V, Sc, Co, Ba, Sr, Nb, Zr, Y, Yb was analyzed using the spectral semi-quantitative method. The cationic-anionic composition, mineralization, suspended solids, pH and concentrations of Mn, Pb, Ni, Cu, Cd, Zn, Co, Fe were determined in surface water samples by atomic absorption spectrometry with electrothermal atomization. The concentration coefficients and anthropogenic load index were calculated. Studies conducted in 2022 established that there was a local impact on surface water. At the site of hydraulic pumping of water used to wash away the soil, an increase in mineralization, suspended solids, color index, and changes in the trace element composition were recorded, showing that manganese, nickel, iron, copper and zinc contribute the most to water pollution levels.

采集猛犸动物化石遗骸的地质生态学问题
摘要 研究地区恶劣的环境条件导致生态系统更新率很低。本文介绍了在因迪吉尔卡河中游寻找和提取猛犸象动物化石遗迹的地点进行地质生态研究的结果。在利用水力冲刷法提取猛犸象动物遗骸的过程中,地貌成分被破坏,基岩随之被沥滤到小溪和河流中,从而导致水生环境的非生物成分恶化。通过分析研究地点生态系统非生物成分的地质生态状态,评估了水力开采猛犸象牙的影响。研究对象是谢苗耶里亚赫河、季列赫季亚赫河和因迪吉尔卡河中游河段的低温土壤、底层沉积物和地表水。土壤和沉积物样本用于测定 pH 值、移动磷和钙。采用光谱半定量法分析了铜、锡、锌、铅、锗、硼、铬、镍、钒、钪、钴、钡、锶、铌、锆、钇、镱的总含量。地表水样本中的阳离子-阴离子成分、矿化度、悬浮固体、pH 值和 Mn、Pb、Ni、Cu、Cd、Zn、Co、Fe 的浓度是通过电热原子吸收光谱法测定的。计算了浓度系数和人为负荷指数。2022 年进行的研究表明,地表水受到了局部影响。在水力抽水冲刷土壤的地点,记录到矿化度、悬浮固体、色度指数的增加以及微量元素组成的变化,表明锰、镍、铁、铜和锌对水污染程度的影响最大。

期刊介绍: Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
