The ecological situation on Shkot Island and the adjacent part of Russky Island in terms of mercury content in soils and leaves of tree and shrubbery vegetation has been analyzed. The main sources of mercury input into geosystems have been revealed. To determine its content in soils and vegetation, 3 and 16 plots have been sampled on Russky and Shkot islands, respectively. It is shown that the soil cover of Russky and Shkot islands is represented by typical and dark brown burozems (brown forest soils) and their pyrogenic analogues. Mercury distribution depends on soil properties in a soil cover and on plant species in vegetation. The results of laboratory research of mercury content in geosystems are presented. Using interpolation method, maps of mercury content in the soil cover and oak leaves (Quercus mongolica) have been compiled for Shkot Island. The average mercury content in the soil cover of Shkot Island and the adjacent part of Russky Island is 81.2 ng/g. The average contents in various plant species are as follows: 26.3 ng/g for Carpinus cordata, 24.5 ng/g for Quercus mongolica, 9.1 ng/g for Artemisia gmelinii. Such variations are caused by different mercury accumulation ability of the plant species. It is assumed that the high mercury content in the soil and vegetation in the eastern part of Shkot Island is due to tectonic features. The maximum soil mercury content on Shkot Island is confined to the Dotovaya Bay coast, which is the island’s main recreation area in summer. Numerous campfires and wood and household waste (first of all, polyethylene) combustion lead to mercury redistribution in the adjoining territories. In terms of mercury content, the ecological setting in the soil-vegetation cover of Russky and Shkot islands is viewed as favorable. The mercury content in soil is much below maximum permissible concentration. Since maximum permissible concentration of mercury in plants is not available, the comparison has been carried out for Clarke values. The mercury content exceeds Clarke values for Carpinus cordata and Quercus mongolica, which can be attributed to natural regional specifics. The obtained data can be used as background indicators.

从树和灌木植被的土壤和叶片中的汞含量分析了斯科特岛和鲁斯基岛附近部分的生态状况。已经揭示了输入到地球系统的汞的主要来源。为了确定其在土壤和植被中的含量，分别在Russky和Shkot岛上采样了3和16个样地。结果表明，Russky和Shkot岛的土壤覆盖以典型的深棕色burozem（棕色森林土壤）及其热解类似物为代表。汞的分布取决于土壤覆盖层中的土壤特性以及植被中的植物种类。介绍了地球系统中汞含量的实验室研究结果。使用插值法绘制土壤覆盖层和橡树叶中的汞含量图（栎属 mongolica）已为Shkot岛进行了编译。斯科特岛和拉斯基岛附近的土壤覆盖层中的平均汞含量为81.2 ng / g。在各种植物物种的平均含量如下：26.3纳克/克为鹅鱼腥草，24.5纳克/克为栎 木，9.1纳克/克为铁杆蒿。这种变化是由植物物种不同的汞积累能力引起的。据推测，斯科特岛东部地区土壤和植被中的汞含量较高，是由于其构造特征造成的。Shkot岛上最大的土壤汞含量仅限于Dotovaya湾海岸，该海岸是该岛夏季的主要休闲区。大量篝火以及木材和家庭废物（首先是聚乙烯）燃烧导致邻近地区的汞重新分布。就汞含量而言，Russky和Shkot群岛土壤植被覆盖区的生态环境被认为是有利的。土壤中的汞含量远低于最大允许浓度。由于无法获得植物中汞的最大允许浓度，已对Clarke值进行了比较。汞含量超过Clarke值Carpinus cordata和Quercus mongolica，可以归因于自然的区域特征。所获得的数据可以用作背景指标。
