СОДЕРЖАНИЕ СОЕДИНЕНИЙ УГЛЕРОДА В КОЛОДЕЗНОЙ ВОДЕ ЧЕРНОВИЦКОЙ ОБЛАСТИ

Впервые проведено исследование содержимого соединений углерода в колодезной воде различных водосборных бассейнов Черновицкой области (за период 2013-2014 гг.). Выявлено, что уровень гидрокарбонатов и диоксида углерода в воде колодцев Северной Буковины не является стабильным, и за исследуемый период показал тенденцию к росту. Доказано, что концентрации НСO3- и СО2 синергируют как с агрохимическими, агроэкологическими показателям, так и с некоторыми характеристиками агронагрузки. Показано определенные различия по содержимым углекислого газа в колодцах, расположенных на территориях разных водосборных бассейнов региона.

Ключевые слова: колодезная вода, гидрокарбонаты, диоксид углерода, агроэкологические показатели, агрохимические показатели, агронагрузка, Черновицкая область, Днестр, Прут, Сирет

CARBON COMPOUNDS CONTENT IN WELL WATER OF CHERNIVTSI REGION

For the first time, the study of the Carbon compounds content in well water of various catchment basins of the Chernivtsi region (2013-2014) was carried out. It is known that Carbon compounds in well water in Ukraine are not normalized. But, they are interest due to their high content in well water and their influence on such indicators as pH, general stiffness and alkalinity. In rural areas well water is used by both drinking and household purposes, and several studies have proved that described above parameters (when they exceed the norms) are cause damage both in the household and for human health. The aim of the research was to compare the Carbon compounds content in well water of various catchment basins of the main rivers of Chernivtsi region by the 2013-2014. The object of research was the well water of Chernivtsi region. This territory we are distributed conditionally along the catchment basins of the main rivers of the region. It is Dniester river basins, Prut river basins and Siret river basins. The research was conducted in the summer. The hydrocarbonate contents and carbonates were determined titerometrically according to generally accepted methods. As a result of the research, it was found that the Carbon compounds content in well water of various catchment basins of the Chernivtsi region is not stable. Thus, the hydrocarbonate concentrations are ranged 342,70-1016,67 mg/dm3, and Carbon dioxide are ranged 54,3-267,3 mg/dm3 by the period 2013-2014. U-criterion Mann-Whitney demonstrated a relative increase the HCO3- and CO2 concentrations in the drinking water of the studied region in 2014, compared with 2013. It was found that the studied Carbon compounds in both years have form a joint association with indicators: agrochemical and agroecological bonitetes, agricultural area under cultivated crops, Phosphorus content in soil. It is indicating synergy of their dispersion. By the Carbon dioxide content in well water the significant differences between the different catchment basins of the main rivers of Chernivtsi region were revealed. Thus, in 2013, the Carbon dioxide content in water samples taken from the wells located on the territory of the Prut River basin was significantly higher than the similar indicators derived for the Dniester River basins and the Siret River basins. In 2014, the Carbon dioxide concentration in water samples taken from the wells located within the Prut River basin was significantly higher compared with similar indicators obtained for the Siret River basin.
