Peculiarities of the Distribution of Dissolved Organic Matter in Water Bodies of Urban Territories
ABSTRAKT
Results of the study of the distribution of dissolved organic matter in the water of Lake Rayduzhne (Kyiv) carried out in 2015-2016 are given in the paper. They include intra-annual and seasonal dynamics of the total content of dissolved organic matter in terms of chemical oxygen demand and permanganate oxidizability, and also seasonal dynamics of the concentration of its individual components (humic acids, fulvic acids, carbohydrates, and protein-like substances) in the surface and near-bottom layers of water. The main hydrochemical characteristics of the water body, including pH, dissolved oxygen concentration, and water saturation by oxygen, are also presented. Seasonal changes in the ratio between the fractions of fulvic acids, carbohydrates, and protein-like substances differing in their molecular mass are also discussed. The concentrations of organic carbon and mass contribution of individual organic components to the total content of dissolved organic matter were calculated.
