Гідрохімічні показники та якість вод водотоків та водойм південно-східної частини водозбору Куяльницького лиману (балки Гільдендорфська, Корсунцівська, озера пересипу)
Представлені результати експедиційних досліджень по встановленню якості вод водотоків та водойм південно-східної частини водозбору Куяльницького лиману (балки Гільдендорфська, Корсунцівська та озера пересипу). Установлено, що екологічний стан і якість вод досліджуваних водних об"єктів є незадовільними через потрапляння скидних комунальних та фільтраційних підземних вод, змиву забруднюючих речовин з навколишніх сміттєзвалищ та об"їзної дороги.
Представлены результаты экспедиционных исследований по установлению качества вод водотоков и водоемов юго-восточной части водосбора Куяльницкого лимана (балки Гильдендорфская, Корсунцовская и озера пересыпи). Установлено, что экологическое состояние и качество воды исследуемых водных объектов является неудовлетворительным вследствие поступления сбросных коммунальных и фильтрационных подземных вод, смыва загрязняющих веществ из окружающих мусорных свалок и объездной дороги.
Estuary Kuyalnik is located in the Odessa region and has valuable natural and health resources. Runoff and water quality in watercourses and reservoirs of south-eastern part of the estuary Kuyalnik play an important role in shaping the regime of this water body. Contemporary state of estuary Kuyalnik is characterized as poor. To improve &the situation carried out a set of measures, including hydrochemical monitoring. In the scientific literature studied in detail issues of water and salt regime, hydrochemical indicators and therapeutic properties of estuary Kuyalnik and river Big Kuy&alnik but hydrochemical regime and water quality of small tributaries of estuary were studied not enough.
Hydrochemical monitoring was conducted in 2012 by scientists OSEU. It was found that the ecological condition of artificial reservoirs is asses&sed as unsatisfactory. In all the studied water bodies of water quality deteriorates due to high concentrations of minerals and nutrients, organic compounds. Characteristics of water quality in water bodies by fisheries management criteria indicates &the predominance of class IV water quality and "very dirty" status of water bodies. It was found that most significantly pollute the water nitrite nitrogen and sulfates.
The results of the class quality and pollution of water by individual agents ma&ke it possible to conclude that the chemical composition of the studied reservoirs from south-eastern part of the estuary Kuyalk cannot be used for fishery needs without any risk to fish and the end user - the person. The limited water exchange, accu&mulation of pollutants in the absence of sufficient water inflow from the catchment, intensive evaporation from the water surface waters, contamination of household water from the private sector, from landfills, receipt of contaminated surface runoff& lead to the accumulation in the waters of excessive concentrations of major ions, nutrient deficiency of (lack of) oxygen dissolved in water and, as a consequence, a significant nutrient load, and consequently the degradation of the individual strea&ms and the entire ecosystem of estuary Kuyalnik. To improve the situation will allow a complex science-based measures to address the impact of main pollutants, improving of water exchange, strict compliance with the requirements of the water protecti&on legislation.
