Abstract —Data on the water quality and the contents of a large group of elements in small lakes are reported for three regions of the Arctic basin: European Russia (Kola region), Western (Yamal–Nenets district) and Eastern (Norilsk region) Siberia. All studied waters are low-salinity and oligotrophic. The air pollution in the lake waters caused the elevated concentrations of many elements. The waters of the Norilsk and Kola regions are enriched in Ni, Cd, As, Sb and Se owing to the distribution of smoke emissions from copper–nickel smelters over long distances. The petroleum industry leads to increased concentrations of V, Pb, and Mo in water. The degree of anthropogenic influence on the lake waters of the Arctic regions was estimated using the Enrichment Factors (EF). The high values of EF for most part of analyzed elements are explained not only by anthropogenic dispersion of elements, but also by a change in the conditions of element migration and the geochemical features of ore occurrences. The calculations demonstrated the effect of anthropogenic dispersion on the enrichment of Arctic waters by a large group of elements, including toxic ones.

北极地区湖泊水域元素分布地球化学特征

摘要——报告了北极盆地三个地区的水质和小湖泊中大量元素含量的数据:欧洲俄罗斯(科拉地区)、西部(亚马尔-涅涅茨地区)和东部(诺里尔斯克地区)西伯利亚. 所有研究的水域都是低盐度和贫营养的。湖水中的空气污染导致许多元素的浓度升高。由于铜镍冶炼厂排放的烟气远距离分布,诺里尔斯克和科拉地区的水域富含镍、镉、砷、锑和硒。石油工业导致水中 V、Pb 和 Mo 的浓度增加。人为对北极地区湖水的影响程度是使用富集因子 (EF) 估算的。大部分被分析元素的 EF 值偏高,不仅是由于元素的人为分散造成的,还可以通过元素迁移条件和矿床地球化学特征的变化来解释。计算表明,人为扩散对北极水域中大量元素(包括有毒元素)的富集产生了影响。
