In the article the results of major and trace elements investigation in freshwater lakes of Vecherny Oasis (Enderby Land, East Antarctica) are considered. Water sampling was carried out during seasonal Belarusian Antarctic expeditions in 2011-2017. Totally 22 water samples from four lakes, three temporal ponds and one water course were collected for major and trace elements determination. The total concentrations of Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Na, Mg, Mn, Mo, Ni, Pb, Sb, Se, Th, Tl, V, W, Zn in all samples as well as more than 40 additional trace elements in 3 samples from lakes were determined using ICP-MS method. It is shown that increase of heavy metals concentration (Cd, Pb, Zn, Sb, Co, Ni, Se, Mn) and As in the lakes compared to temporary ponds can be explained by anthropogenic impact including previous human activity in the oasis in late 1970th - early 1990th. The maximum concentrations of a number of technophilic elements (Pb, Mo, Mn, V, Sb, Zn) in Lake Nizhneye are possibly connected with the its lowest hypsometric location in catchment and the drainage of the territory impacted by past and present human activity.
本文考虑了南极洲东部范德比尔特地韦彻尔尼绿洲（Vecherny Oasis）淡水湖的主要和微量元素调查结果。水样是在 2011 年至 2017 年期间的白俄罗斯南极考察季采集的。总共从四个湖泊、三个临时池塘和一条水道采集了 22 个水样，用于测定主要和微量元素。使用 ICP-MS 法测定了所有水样中的 Ag、Al、As、Ba、Be、Ca、Cd、Co、Cr、Cu、Fe、K、Na、Mg、Mn、Mo、Ni、Pb、Sb、Se、Th、Tl、V、W、Zn 的总浓度，以及来自湖泊的 3 个样本中的 40 多种痕量元素。结果表明，与临时池塘相比，湖泊中重金属（Cd、Pb、Zn、Sb、Co、Ni、Se、Mn）和 As 浓度的增加可归因于人类活动的影响，包括 20 世纪 70 年代末至 90 年代初绿洲内的先前人类活动。在 Nizhneye 湖中，一些亲石元素（Pb、Mo、Mn、V、Sb、Zn）的最大浓度可能与其在集水区中的最低高程位置以及受过去和现在人类活动影响的流域排水有关。
