Abstract

The composition and content of phenol carboxylic acids was studied in water bodies among higher aquatic plants of various ecological groups: emergent (Typha angustifolia L., Scirpus lacustris L., and Phragmites australis (Cav.) Trin. ex Steud.), submerged (Ceratophyllum demersum L. and Myriophyllum spicatum L.), and with floating leaves (Trapa natans L. and Nuphar lutea L.). The following acids were found in the water among higher aquatic plants: benzoic, lilac, vanillic, gallic, n-oxybenzoic, protocatechuic, α-resorcylic, β-resorcylic, salicylic, ferulic, caffeic, cinnamic, coumaric, and sinapic. Their total concentration in the water among the specimens of T. angustifolia accounted for 114.7 μg/L, Sc. lacustris - 24.71 μg/L, T. natans - 56.14 μg/L, N. lutea -19.3 μg/L, C. demersum -25.42-38.66 μg/L, and M. spicatum - 1.42-2.83 μg/L. The analysis of the content of phenol carboxylic acids in the water among the specimens of Ph. australis during the spring-autumn period revealed significant differences both in the ratio of individual acids and in their distribution by groups. The maximal concentration of benzoic and salicylic acids in the water was registered at the beginning of Ph. australis development, whereas the maximal content of vanillic and gallic acids - during plant active vegetation. The lowest content of cinnamic and ferulic acids was recorded at the beginning of vegetation season. Cluster analysis of the content of phenol carboxylic acids in the water among the specimens of C. demersum and M. spicatum at two sampling stations (Sobache Gyrlo Bay and Verblyud Bay in the Kaniv Reservoir) made it possible to reveal two groups of the studied substances. The first group included benzoic and gallic acids and the second group - other acids. The use of the principal component analysis (PCA) made it possible to establish a significant correlation between the composition and content of phenol carboxylic acids in the water among higher aquatic plants and dominant plant species. This fact is indicative of the leading role of higher aquatic plants in the formation of the pool of these substances in the water.

不同生态类群高等水生植物水体中酚羧酸的含量

研究了不同生态类群的高等水生植物水体中酚羧酸的组成和含量:突生();L.， Scirpus lacustrisL.， 芦苇(Cav)。指标。(ex Steud.)，浸没(Ceratophyllum demersumL. and L.)，并带有浮叶(Trapa natansL. and Nuphar luteal .)。在高等水生植物的水中发现了以下酸:苯甲酸、丁香酸、香草酸、没食子酸、-氧苯甲酸、原儿茶酸、-间环酸、-间环酸、水杨酸、阿魏酸、咖啡酸、肉桂酸、香豆酸和辛酸。它们在水中的总浓度在T的标本中。angustifolia占114.7 μ g/L;lacustris- 24.71 μg/L， T;natans- 56.14 μg/L， N;lutea-19.3 μg/L， C;demersum-25.42-38.66 & μ;g/L， M;spicatum- 1.42-2.83 μ g/L。对< 1 >Ph. 1样品水中酚羧酸含量进行了分析。australis在春秋时期，个体酸的比例和群体分布都有显著差异。水体中苯甲酸和水杨酸的最大浓度记录在Ph值开始时。australis而香草酸和没食子酸含量最高的时期是植物活跃植被时期。肉桂酸和阿魏酸含量在植被季开始时最低。C样品水中酚羧酸含量的聚类分析。demersum和& lt; i> M。spicatum在两个采样站(Sobache Gyrlo湾和Kaniv水库的Verblyud湾)进行的研究，有可能揭示两组研究物质。第一组是苯甲酸和没食子酸，第二组是其他酸。利用主成分分析(PCA)，可以建立高等水生植物和优势植物水体中酚羧酸的组成和含量之间的显著相关性。这一事实表明，高等水生植物在水中这些物质池的形成中起着主导作用。

期刊介绍： This journal contains translations from the premier Russian and Eastern European periodicals in aquatic biology and aquatic ecosystems, supplemented by original articles from elsewhere. The journal publishes in the area of physiology, biochemistry, systematics, ecology and conservation of freshwater fish, invertebrates, vascular plants, zoo- and phytoplankton, as well as freshwater quality and toxicology. While most of the papers deal with inland waters, the journal also publishes articles reporting on expeditionary work, especially the Antarctic and tropical seas. Hydrobiological Journal is valuable to freshwater and marine biologists and chemists, limnologists, environmental scientists, oceanographers, and toxicologists.
