Abstract

The Russian Federation regularly participates in the international program of the Acid Deposition Monitoring Network in East Asia (EANET). Two regions in the Asian Russia were selected for monitoring research: South-Eastern Siberia (three sites) and Far East (one site). A database on the chemical composition of atmospheric aerosol has been compiled over the operation period. The spatial and temporal variability of the ion composition of aerosol over five-year periods from 2001 to 2024 was studied using the ratio of the summed concentrations of the main ions. Based on data from other projects, some relevant trace elements in atmospheric aerosol were analyzed: Li, Al, Ti, V, Mn, Fe, Sr, Th, U, Ba, and Co (of terrigenous origin) and Cr, Cu, and Ni (of nonterrigenous origin). Their contribution to the total level of atmospheric air pollution at the EANET monitoring sites was assessed. The monitoring results on atmospheric depositions can be used for practical assessment of the environmental conditions, scientific research, and public information.

俄罗斯EANET站大气气溶胶化学成分的长期研究

俄罗斯联邦定期参加东亚酸沉降监测网（EANET）国际方案。俄罗斯亚洲的两个地区被选中进行监测研究：西伯利亚东南部（三个地点）和远东（一个地点）。在行动期间，已编制了大气气溶胶化学成分的数据库。利用主要离子浓度总和的比值，研究了2001 - 2024年五年期间气溶胶离子组成的时空变异性。在其他项目资料的基础上，分析了大气气溶胶中相关微量元素：Li、Al、Ti、V、Mn、Fe、Sr、Th、U、Ba、Co（陆源）和Cr、Cu、Ni（非陆源）。评估了它们对环境网监测点大气污染总水平的贡献。大气沉积监测结果可用于实际环境评价、科学研究和公共信息。

期刊介绍： Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
