Abstract

The results of studying the chemical composition of water in Northern Baikal and in the rivers flowing into it are analyzed. It is shown that the influence of river water on forming the chemical composition of water in this part of the lake is observed at the distance of 1–3 km from the cofferdam separating the Upper Angara delta from Lake Baikal. In spring and early summer, the expansion of river water in the lake is constrained by a thermal bar. In summer, a biological barrier is formed in the mixing zone, where the minimum biogenic element concentrations of and maximum phytoplankton concentrations are registered. The increased concentrations of phosphorus have been revealed in the shallow area in winter, which points to the contamination of bottom sediments and secondary pollution of water. The increased content of phosphorus in the water may be a sign of the eutrophication of Northern Baikal.

贝加尔湖北部与其支流水混合区水的化学成分的形成
摘要 分析了贝加尔湖北部和流入贝加尔湖的河流中水的化学成分研究结果。结果表明,在距离安加拉河上三角洲与贝加尔湖之间的围堰1-3公里处,可以观察到河水对这部分湖水化学成分形成的影响。在春季和初夏,河水在湖中的扩张受到热障的限制。夏季,在混合区形成了生物屏障,这里的生物元素浓度最低,浮游植物浓度最高。冬季,浅水区的磷浓度增加,这表明底泥受到污染,水体受到二次污染。水中磷含量的增加可能是贝加尔湖北部富营养化的迹象。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
