چکیده
Hodnotenie a charakterizácia vybraných škodlivín v prípade zdrojov povrchovej vody High quantities of organic matter can reduce the chemical and biological quality of river water. The key indicator of the oxygenation status of water bodies is the biological oxygen demand (BOD) and ammonium. These are main indicators for the water quality classification. Although countries have different river classification schemes they give a general indication of river quality, respective of whether there has been an improvement or not. The paper illustrates the current situation regarding the biological oxygen demand and the concentrations of ammonium in river classification schemes.

Rivers can absorb certain amounts of contamination relying on different factors such as: river discharge, the primary conditions of the river, the river depth, discharge and the river viscosity of the offloaded wastes in the river. From parameters of water quality point of view, it is recom-mended to determine some parts of the river which are lower than the standard level in order to find out ...
