摘要

对位于伏尔加-阿赫图巴洪泛区境内的水体(杜达切诺克浅水河道)进行了环境恢复后的生态现状评估。结果发现,几乎所有研究指标都符合批准的质量标准,但锶除外 - 4.5 毫克/升(MPC - 0.4 毫克/升(2016 年 12 月 13 日第 552 号命令),MPC - 7 .0 毫克/升(SanPiN 1.2.3685-21 No. 2,2021 年 1 月 28 日))和钡 - 1.25 毫克/升(MPC - 0.74 毫克/升(552 号命令,2016 年 12 月 13 日),MPC - 0.7 毫克/升(SanPiN 1.2.3685-21 No.)由此得出结论,可以为水体分配碳氢化合物类(主要阴离子)、钙类(主要阳离子)和第二类。对底层沉积物的研究表明,氯化物(36 毫克/千克)是主要阴离子之一,钙(27 毫克/千克)和钠(27 毫克/千克)是主要阳离子,这与获得的水体化学成分数据一致。对底层沉积物的化学和毒理学参数进行了分析。结果表明,金属和农药的定量含量没有超过最高允许浓度。

Current Ecological State of the Volga-Akhtuba Floodplain Water Bodies (Using the Example of Dudachenok Shallow Channel)
Current ecological state assessment of the water body located on the Volga-Akhtuba floodplain territory (Dudachenok shallow channel) after its environmental rehabilitation was carried out. It was found that almost all the studied indicators correspond to the approved quality standards with the exception of strontium – 4.5 mg/l (MPC – 0.4 mg/l (Order No. 552 dated December 13, 2016), MPC – 7 .0 mg/l (SanPiN 1.2.3685-21 No. 2 dated January 28, 2021)) and barium – 1.25 mg/l (MPC– 0.74 mg/l (Order No. 552 dated December 13, 2016), MPC – 0.7 mg/l (SanPiN 1.2.3685-21 No. 2 dated January 28, 2021)). It is concluded that it is possible to assign a hydrocarbonate class (predominant anion), calcium group (predominant cation) and second type to a water body. A study of bottom sediments revealed that chloride (36 mg/kg) is one of the predominant anions, calcium (27 mg/kg) and sodium (27 mg/kg) are the predominant cations, which agrees with the obtained water chemical composition data. Chemical and toxicological parameters of bottom sediments were analyzed. It was determined that the quantitative content of metals and pesticides does not exceed the maximum permissible concentrations.

期刊介绍: The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
