Blue-green algae, or cyanobacteria, may be prevalent in our rivers and tap water. These minuscule bacteria can grow swiftly and form blooms in warm, nutrient-rich water. Toxins produced by cyanobacteria can pollute rivers and streams and harm the liver and nervous system in humans. This review highlights the properties of 25 toxin types produced by 12 different cyanobacteria genera. The review also covered strategies for reducing and controlling cyanobacteria issues. These include using physical or chemical treatments, cutting back on fertilizer input, algal lawn scrubbers, and antagonistic microorganisms for biocontrol. Micro-, nano- and ultrafiltration techniques could be used for the removal of internal and extracellular cyanotoxins, in addition to powdered or granular activated carbon, ozonation, sedimentation, ultraviolet radiation, potassium permanganate, free chlorine, and pre-treatment oxidation techniques. The efficiency of treatment techniques for removing intracellular and extracellular cyanotoxins is also demonstrated. These approaches aim to lessen the risks of cyanobacterial blooms and associated toxins. Effective management of cyanobacteria in water systems depends on early detection and quick action. Cyanobacteria cells and their toxins can be detected using microscopy, molecular methods, chromatography, and spectroscopy. Understanding the causes of blooms and the many ways for their detection and elimination will help the management of this crucial environmental issue.

“…The increase in frequency and duration of blue-green algal (cyanobacterial) blooms poses serious threats to the environment, including degradation of local and global water resources [1][2][3][4][5][6]. This is due to the production of a wide range of toxic secondary metabolites, namely cyanotoxins, by some species of planktonic microalgae (Microcystis aeruginosa (Kützing) Kützing; Dolichospermum flosaquae (Bornet & Flahault) P.Wacklin, L.Hoffmann & Komárek (=Anabaena flosaquae Brébisson ex Bornet and Flauhault); Aphanizomenon flosaquae Ralfs ex Bornet and Flahault; Planktothrix agardhii (Gomont) Anagnostidis and Komárek; Planktothrix rubescens (De Candolle ex Gomont) Anagnostidis and Komárek; Cylindrospermopsis raciborskii (Woloszynska) Seenaya and Sabbaraju (=Raphidiopsis raciborskii (Woloszynska) Aguilera, Berrendero Gómez, Kastovsky, Echenique and Salerno), etc.)…”

Intense “blooming” of cyanobacteria (blue-green algae) caused by eutrophication and climate change poses a serious threat to freshwater ecosystems and drinking water safety. Preventing the proliferation of cyanobacteria and reducing water nutrient load is a priority for the restoration of eutrophic water bodies. Aquatic plants play an important role in the function and structure of aquatic ecosystems, affecting the physiochemistry of the water and bottom sediments, primary production, and biotic interactions that support a balanced ecosystem. This review examines the inhibitory effect of aquatic vascular plants on harmful blooms of cyanobacteria. Aquatic plants are able to successfully inhibit the growth of cyanobacteria through various mechanisms, including by reducing nutrient and light availability, creating favorable conditions for the development of herbivorous zooplankton, and releasing allelopathic active substances (allelochemicals) with algicidal effect. Allelopathy is species-specific and therefore acts as one of the key mechanisms by which the development of cyanobacterial populations in aquatic ecosystems is regulated. However, allelopathic activity of aquatic vascular plants depends on various factors (species characteristics of aquatic plants, area, and density of overgrowth of water bodies, physiochemical properties of allelopathically active substances, hydrological and hydrochemical regimes, temperature, light intensity, etc.), which may regulate the impact of allelochemicals on algal communities. The paper also discusses some problematic aspects of using fast-growing species of aquatic vascular plants to control cyanobacterial blooms.

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.
