“…Because of increasing water consumption through many human activities such as household, agriculture, industry, and transportation may create water pollutions including bacterial contaminations in water, , so access to clean water is necessary for safe life. Especially, Staphylococcus aureus and Escherichia coli are commonly found in contaminated water − as Gram-positive and Gram-negative bacteria, and E.…”

Bacteria contaminations in water are concerned as environmental effects including human health, so water treatment is required before use. Although using extracted plant is interesting because of their good chemical compounds for bacterial inhibitions, no study has applied the extracted plant in bead materials for disinfection in wastewater. The current research attempted to extract Cratoxylum formosum and Polygonum odoratum for the synthesis of C. formosum beads (CFB) and P. odoratum beads (POB), and their antibacterial efficiencies were investigated by agar diffusion tests, antibacterial batch tests, adsorption isotherm and kinetics, and material reusability. C. formosum and P. odoratum leaves were ethanol-extracted, and their bead materials (CFB and POB) were synthesized. Furthermore, their characterizations of surface area, chemical compositions, and chemical functional groups were investigated. For field emission scanning electron microscopy and focused ion beam (FESEM-FIB) analysis, CFB and POB had spherical shapes with coarse surfaces. Energy-dispersive X-ray spectrometry (EDX) analysis of CFB and POB illustrated five main chemical compositions, which were carbon (C), oxygen (O), calcium (Ca), chlorine (Cl), and sodium (Na), whereas Fourier transform infrared (FTIR) spectroscopy analysis identified seven main chemical functional groups, which were O−H, C−H, CO, CC, N−H, C−O, and C−Cl. Agar diffusion tests confirmed the abilities of CFB and POB to inhibit both Staphylococcus aureus and Escherichia coli, and batch experiments examined high antibacterial efficiencies of CFB of almost 100% on both bacterial types. The adsorption isotherm of CFB corresponded to the Freundlich model, which is related to the physiochemical adsorption process with multilayer or heterogeneous adsorption, and the adsorption kinetics of CFB was correlated to the pseudo-second-order kinetic model, which involved chemisorption relating to physiochemical interaction. Moreover, the desorption experiment confirmed the reusability of CFB. Therefore, CFB is a potential material to possibly apply for disinfection of wastewater.

“…On the other hand, changes in the vegetation cover of water bodies occur as a result of natural and anthropogenic factors, and the state of aquatic vegetation is an objective indicator of the processes occurring within the catchment area and aquatic ecosystems. Anthropogenic trans-formation is primarily manifested in the distribution of submerged hydrophytes, which are known to be most sensitive to the state of the aquatic environment and are used as its bioindicators (Dubyna et al, 1993;Zub et al, 2018;Fedonyuk et al, 2020;Mushtaq et al, 2020). For example, the current population trend of Sparganium natans is decreasing in Europe and globally; threats: natural system modifications and pollution (agricultural & forestry effluents) (The IUCN Red List of Threatened Species, 2014).…”

Study and analysis of hydrophilic flora diversity are important parts of environmental research due to various functions of vascular macrophytes in freshwater ecosystems, which deteriorate under the influence of anthropogenic activity and climate change. The aim of this study is to analyze the hydrophilic flora diversity (taxa, biology, ecology, and conservation status of species) and current population trends in the Sluch River basin, the largest tributary of the Horyn River (the Pripyat River basin), within the Polissya Lowland in the northern-west region of Ukraine. The list of hydrophilic flora is based on materials of the authors’ field researches in 2014–2020 within the upper and middle parts of the river basin, herbarium materials, and archive data. The study shows that the natural flora consists at least of 105 species of vascular plants belonging to 66 genera, 36 families, and 22 orders. Structural analysis shows the predominance of a few families in the systematic structure of the flora (Cyperaceae, Potamogetonaceae, Poaceae, Ranunculaceae, Plantaginaceae, and Typhaceae) and genera (Potamogeton, Carex); the dominant categories are hemicryptophytes and geophytes, entomophiles and anemophiles, heliophytes and hygrohelophytes. C- and S-strategists are dominant. This is the generally typical taxonomic and ecological structure of the hydrophilic flora of water bodies in the Pripyat River basin. The list of rare species includes 20 species from 15 genera and 12 families, for instance, species listed as vulnerable in The Red Book of Ukraine (Juncus bulbosus, Utricularia intermedia, Nymphoides peltata). Even rare and vulnerable species can form numerous populations in some localities, for example, Nymphoides peltata and Calla palustris. Five alien species were identified (Acorus calamus, Elodea canadensis, Zizania latifolia, Bidens frondosa, and Echinocystis lobata), some of which tend to expand and displace aboriginal species. In the future, it will be important to further study the structure and changes in the hydrophilic flora of the region under conditions of anthropogenic impact, to monitor the dynamics of populations of alien species, and to develop conservation measures for rare species and communities.

“…Worldwide, an enormous amount of phosphate-containing industrial and domestic wastewater and agricultural runoffs get discharged into natural water bodies, including lakes and rivers. 6–8 Considering the harmful impacts of excessive phosphate in the water bodies, the Environmental Protection Agency (EPA) declared the maximum permissible level and discharge limit to be 0.1 mg L −1 and less than 0.05 mg L −1 phosphate ions, respectively. Hence, the development of certain proficient methods for removing phosphate from the water and wastewaters is essential to sustain aquatic ecosystems.…”
