Anthropogenic Impact on Organic Matter Pollution of the Bregava River

Immoderate and thoughtless use of water causes a series of unwanted consequences for nature and people. Any deviation of the water quality from the prescribed physical, chemical and biological characteristics of drinking water can be considered as pollution and contamination. The Bregava River originates from the permanent springs of Bitunja and Hrgud and the periodic springs of Mali and Veliki Suhovic. Stolac is the larger place through which it flows. In this paper analyzed physical and chemical parameters which determine the oxygen balance of the Bregava River watercourse, in four different seasons.The oxygen balance is determined by the amount of waste matter that has entered the environment and processes that affect their further fate. Oxygen balance of the waters should indicate the level of loading of the watercourse with organic matter as a result of anthropogenic influence, and their dependence on climatic conditions.
