Abstract

We consider the chemical composition (ions, elements, and polycyclic aromatic hydrocarbons) of atmospheric aerosol in different regions of the North Atlantic, European and Russian parts of the Arctic Ocean, and northern latitude and Far East seas. The studies were carried out onboard marine ships along their cruising routes (RV Akademik Tryoshnikov, RV Akademik Mstislav Keldysh, and RV Professor Multanovsky). The air samples were collected using the method accepted in the international networks operating under the Acid Deposition Monitoring Network in East Asia (EANET) and European Monitoring and Evaluation Programme (EMEP). The average sum of ion concentrations and the concentrations of individual ions in the aerosol over the seas in the North Atlantic and in the European part of the Arctic Ocean is consistent with measurements in the Laptev and Kara Seas in 2018 and 2019. The high concnetrations of PAHs in aerosol in seas and the Arctic Ocean in the central part of the Russian Arctic coincide with high concentrations of ions and trace elements in the aerosol composition. A difference is noted in the distribution of concentrations of trace elements in aerosol composition between seas of the North Atlantic and central region of the Russian Arctic, which possibly points to different sources of these components.

2018-2019年北极地区和沿海洋探险路线的毗邻海域大气气溶胶的化学组成

摘要

我们考虑了北大西洋，北冰洋的欧洲和俄罗斯部分以及北纬和远东海不同地区的大气气溶胶的化学成分（离子，元素和多环芳烃）。这些研究是沿着船上的巡游路线进行的（RV Akademik Tryoshnikov，RV Akademik Mstislav Keldysh和RV Professor Multanovsky）。使用在东亚酸沉降监测网络（EANET）和欧洲监测与评估计划（EMEP）下运作的国际网络所接受的方法来收集空气样品。北大西洋和北冰洋欧洲部分海域的离子浓度和气溶胶中各个离子的平均浓度之和与拉普捷夫和卡拉海在2018年和2019年的测量值一致。俄罗斯北极中部海洋和北冰洋气溶胶中的多环芳烃与气溶胶成分中的高浓度离子和微量元素相吻合。在北大西洋海域与俄罗斯北极中部地区之间，气溶胶成分中微量元素的浓度分布存在差异，
