The article considers the results of research from 2015 to 2019 on the study of hydrochemical indicators and the content of heavy metals in the ecosystem components of the small Arguzikha river , a left-Bank tributary of the Amur river (water, bottom sediments, macrophytes, birds ’ feathers). High oxygen content in the water (8.8-15.9 mgO2/dm3) and high BOD5 values (6-12 mgO2/dm3) in the middle and lower reaches of the Arguzikha river indicate the process of eutrophication. The value of permanganate oxidability (6.8-15.5 mgO/dm3) characterizes the high content of organic substances in water. In the spring, nitrate nitrogen (3.45-6.39 mgN-NO3-/dm3) was found in the water of the Arguzikha river, which had a pyrogenic origin. In the summer the rainy season was dominated by ammonium nitrogen (2.34 mgN-NН +/dm3). The high content of total phosphorus (0.337-0.609 mg/dm3) in the river water was in the spring. In the spring of 2015, the concentration of lead in the lower reaches of the river reached 6.36 µg/dm3, during the subsequent time, the lead content in the Arguzikha water was less than the MPC. Toxic concentrations of lead (> 30 mg / kg) and manganese (> 300 mg/kg) were found in macrophytes of Nymphoides peltata and Myriophyllum spicatum. In the feathers of waterfowl of the Arguzikha river the content of heavy metals decreases in a row Fe>Zn>Cu>Pb>Mn>Сг>Ni>Cо>Cd. The feathers of Anas acuta and Anas querquedula contained Pb 17.7 mg/kg and 22.2 mg/kg, Cd 0.15 mg/kg and 0.08 mg/kg, respectively.

In addition to the distribution of modified water of the Amur River runoff in the Aniva Bay, remote from its mouth, according to the data from 2012–2013 (Shevchenko G.V., Chastikov V.N. Distribution of the Amur waters in the eastern part of the Aniva Bay in late autumn. Meteorology and Hydrology, 2021, no. 1), the materials of the oceanological survey carried out in this basin in mid-November 2001 are presented. It is shown that desalinated water entered the bay in an unusually wide stream in the upper 30-meter layer and occupied a vast area, almost to the middle of the bay. At the same time, the differences in salinity with local waters were less than usual. The most probable reason for such specific features of oceanological conditions in 2001 was an increase (by about 30% in comparison with the usual values) of the wind of west-northwest rhumb of an offshore character. The obtained results show that the influence of this water can manifest itself not only near the eastern coast of the bay, as was demonstrated in the mentioned article, but also at a distance of more than 30 km from it. Accordingly, abrupt decreases in salinity can affect the marine biota not only of the coastal complex, but also inhabiting the central part of the bay.

Transport Potential

The purpose of the article is to analyze the significance of the Amur River transport activity in the 1990s for interregional Russian-Chinese cross-border coopera-tion in the Far East. Using the materials in Chinese as well as archival documents, the author examines the process of border ties resumption between Russia and China in the Far East after the normalization of rela-tions between the countries. The peculiarities of the river fleet functioning on the Amur during the period of socio-economic reforms of the last decade of the 20th century in Russia are studied. The characteristic of the Amur River transport potential is presented. The prob-lems of the Amur River transport in the development of cooperation between the Russian Amur Region and the Chinese province of Heilongjiang in the context of Rus-sian-Chinese relations at the interstate and interregion-al levels are structured.
