Abstract

The Danube is the second largest river in Europe, having 2857 km long, with a drainage area of almost 801,500 square kilometers. The urbanization, industrialization and agriculture mechanization development have led to the deterioration of Danube water quality due to various contaminants. The aim of this research was to evaluate the main physico-chemical indicators of Danube water, Chilia branch, mainly in Isaccea, Chilia, Izmail and Vilkovo areas, located in the Romania- Ukraine border region. The samples were collected during year 2014, in spring and autumn seasons, and were analyzed in the laboratory for Ecology and Exploitation of Aquatic Resources, at the Department of Aquaculture, Environmental Sciences and Cadastre, Faculty of Food Science and Engineering, "Dunărea de Jos" University of Galati. Sampling and analysis of physical and chemical indicators were performed in accordance with the current standards, available for each indicator separately. The investigated physico-chemical parameters were: pH, dissolved oxygen (DO) and nutrients (N-NH<subscript>4</subscript><superscript>+</superscript>, N-NO<subscript>3</subscript><superscript>-</superscript>, P-PO<subscript>4</subscript><superscript>3+</superscript>). The results of this research showed that in the Isaccea, Chilia, Izmail and Vilkovo areas, the physico-chemical indicators are slightly above the admissible values mentioned in surface water quality standard classification (No.161/2006). This is most probably a direct result of human and industrial activities from the previous mentioned areas. [ABSTRACT FROM AUTHOR]
