The role of the amino acids' transamination in the tissues of fish ( Cyprinus carpio L.) and mollusk ( Unio pictorum L.) in homeostasis of protein metabolism under the impact of 2 and 5 maximum permissible concentrations (MPC) of Mn²⁺, Zn²⁺, Cu²⁺ and Pb²⁺ ions was studied. Changes in the aspartate amino-t...

The use of M. × giganteus in phytoremediation requires treatment of the contaminated biomass, which can be done by pyrolysis to produce biochar. Due to its potentially detrimental properties, the application of biochar in soil remediation must first be evaluated on a test plant to infer how the growth process was affected by the impact on soil para...

To get additional tools for the assessment of carbon sequestration, along with the visual assessment of soil coloration with the applying of A. H. Munsell’s atlas, the analysis of color and spectral characteristics of soil using portable colorimeter NixPro and reflectometer Our Sci Reflectometer was carried out in this study. Elemental analysis of...

The metal content (Ferrum, Cobalt, Manganese, Zinc, Copper) in water, bottom sediments and tissues of freshwater fish (carp, crucian carp, pike, perch) from small rivers of Western Podillya (Seret, Strypa, Zolota Lypa) was studied. High concentrations have been found in the water and bottom sediments of the Ferrum and Manganese, which is probably d...

In the conditions of vegetation experiment the photosynthetic apparatus features of the of Miscanthus x giganteus leaves have been studied under the influence of soil contamination by diesel fuel (0.25—5 g/kg) and application of biochar fertilizer (5 %). The aim was to research the photosynthetic activity parameters as markers of the adaptability o...

The content of monosaccharides in flower nectar, nectar productivity, as well as the viability of pollen of hybrids Brassica napus L. Kuga, Dk Expression, Emerald (Smaragd) and Abacus were studied. It was found that during the first and second pollen crops the most intensive germination of pollen grains occurred in Emerald (Smarahd) (75 % and 87 %,...

Miscanthus × giganteus (M. × giganteus) is a perspective plant produced on marginal and contaminated lands with biomass used for energy or bioproducts. In the current study, M. × giganteus development was tested in the diesel-contaminated soils (ranged from 250 mg kg−1 to 5000 mg kg−1) and the growth dynamic, leaves quantity, plants total area, num...

Lipids are a heterogeneous group of chemical compounds that are found in all animal and plant organisms and combine based on common properties. The physiological role of lipids in fish is extremely important and diverse. They perform a number of functions, including energetical, structural, regulatory and others. The authors analyzed the data in th...

The osmotic resistance of erythrocytes and the content of hemoglobin in the blood of carp (Cyprinus carpio L.) and pike (Esox lucius L.) under the action of Fe3+ ions at concentrations of 0.2 and 0.5 mg/dm3, were under study which corresponded to 2 and 5 maximum permissible concentration (MPC). The research demonstrated that increased concentration...

The morphometric characteristics of the most common commercial fish were studied: carp – Cyprinus carpio L., pike – Esox lucius L., crucian carp– Carassius auratus gibelio Bloch. and perch – Perca fluviatilis L., two years old, with an average mass of 290–330 g., 300–350 g., 150–230 g. and 170–230 g. respectively, caught from the small rivers of th...

The soils of Ukraine have been well studied, however this did not prevent them from the intensive degradation processes. About a third of the arable land is eroded, about 20% of organic matter is lost, almost all the arable land in the subsoil is compacted, the nutrient forms of mobile phosphorus and especially calcium are significantly reduced, ca...

Nowadays the majority of rivers in Ukraine in general and the Volyn region in particular are contaminated as environmental protection measures are not taken. The Turia and Prypiat Rivers also suffer from human activity. They have recently undergone considerable anthropogenic pressure, which caused water pollution with industrial, municipal wastewat...

From the launched research we obtained the aggregate data, that not only confirm and broaden our concept of the important role of protein and nucleic metabolism in the processes of detoxication of heavy metals ions and formation of resistance to them, but also allow making an integral estimation of biochemical reaction of carp organism to chronic i...

The influence of ions of Manganese, Zinc, Copper and Lead in two concentrations, which corresponded to 2 and 5 MPC, on the content of free amino acids in the carp organism was studied. It is shown, that free amino acids are compounds, that are actively used in the energy supply of fish organisms. Their metabolism is one of the factors, that provide...

The content of individual metals in carp, crucian carp, perch and pike tissues from small rivers of Western Podillya is investigated. It is shown, that for different metals there are individual patterns of accumulation in different tissues of the organism. However, the general tendencies that determine cellular transformations in fish are: tissue-s...

The fractional composition of lipids in the gills, liver, kidneys and muscles in narp (Cyprinus carpio) and pike (Esox lucius) under the impact of 0.2 and 0.5 mg/dm of Fe3+ ions in water, which correspond to 2 and 5 maximal permissible concentrations, was studied. Changes in lipid content in fish tissues depended on Fe3+ ions concentration in water...

The impact of elevated concentration (2 and 5 MPC) of Fe³⁺ ions in water on content of nucleic acids and proteins in liver and muscles of carp (Cyprinus carpio L.) and pike (Esox lucius L.) was studied. Metabolic activity of the nucleic acids and proteins in fishes' tissues under experimental conditions was shown to change. Mechanisms of biochemica...

The changes in lipid content in the gills of carp and pike under impact of cadmium ions was studied. Toxic impact caused changes of total lipids content, individual fractions of phospholipids and their ratio.

The changes of the lipids' content in mitochondrial membranes of the pike (Esox lucius) gills under elevated concentration of zinc ions were studied. Zinc ions were found to change content of individual phospholipids fractions. The role of mitochondrial phospholipids in the fish adaptation to zinc ions is discussed.

Impact of the crude oil and diesel fuel on activity of succinate dehydrogenase and cytochrome-c-oxidase in the gills and liver of fish has been studied. Activity of these enzymes was shown to increase under the effect of diesel fuel, and decrease under the effect of the crude oil. Conclusion has been made that row oil is more toxic for the energy m...

Impact of the oil products on activity of ATPases of the carp gills has been studied. It was stated that low concentrations of diesel oil (1, 5 MPC) had no toxic effect, moreover they increased fish survivability. Toxic effect of oil (10, 20 MPC) mainly exhibits itself as changes of the cell membranes penetrability with participation of ATPase syst...

The effect of the crude oil (concentration from 5 to 30 maximum permissible concentrations (MPC)) on activity of succinate dehydrogenase, transamination enzymes and glycogen content in the tissues of carp has been studied. Suppression of the succinate dehydrogenase link of the respiratory chain was noted, which plays an important role in compensato...

Effect of the crude oil and diesel fuel in the concentration from 5 to 30 MPC (maximal permissible concentration) on the activity of transamination enzymes in gills, liver and muscles of carps (Cyprinus carpio) has been investigated. It was stated, that heightened concentration of the diesel fuel in water has more toxic effect on the fishes' vital...
