Динаміка вмісту нітрогеновмісних сполук у гідроекосистемах річок Прип’ять та Турія

Abstract

Досліджено вміст нітрогеновмісних сполук у воді річок Прип’ять та Турія Волинської області в різні сезони року. Здійснена екологічна оцінка якості води р. Турія та р. Прип’ять.

Nowadays, most of the rivers of Ukraine in general and the Volyn region in particular are contaminated with ordinary human negligence, as environmental measures are not sufficiently implemented. The Turia and the Pripiat River are also an exception. In recent years, they have undergone considerable anthropogenic pressure, which caused water pollution with industrial, municipal wastewater, deterioration of water quality, overgrowth of the bed, flowering of water, etc. In this regard, the assessment of water quality is extremely important. Inorganic nitrogen compounds (ammonium and nitrates) are characterized by high biological activity. They determine the trophic state and productivity of reservoirs. It should be noted that an increase in the concentration of nitrogen-containing compounds leads to a burst of development of blue-green algae with a shift of equilibrium in the aquatic ecosystem towards eutrophication process. The concentrations and the peculiarities of the spring and summer redistribution of inorganic nitrogen compounds in the water of the Pripiat and Turia Rivers are investigated. An indicative tropho-saprobiological evaluation of the status of the hydro-ecosystems was conducted. The results obtained provide a theoretical and scientific basis for establishing the regulatory factors that determine the content of Nitrogen (ammonium and nitrate) compounds in the water of the Pripiat and Turia rivers. The identified features can be used in the development of recommendations for the development of biomonitoring methods for hydro-ecosystems. Targeted environmental assessment of the water quality of the Pripiat and Turia Rivers is carried out.
