Physical and chemical methods of the analysis application for an estimation of superficial waters quality

Decrease in the level of toxic and harmful substances in the surface waters is an actual approach today. To improve the quality of superficial waters it is necessary to develop optimal program of monitoring for the direct source of water supply. This work includes studying some of the contributors to the surface water pollution and the harmful substances within their waste waters. One aim of the work was to study integral parameters which can help to decrease the amount of analyses and to increase their accuracy. An integral nature of chemical oxygen demand index was demonstrated in this work. Dependences of BOC5, nitrite ions, phosphate ions, ammonium ions and lignin substances concentrations on chemical oxygen demand were obtained. Correlations obtained may be used to determine a value of BOC5 and level of concentrations of some substances in superficial waters. This work has shown the possibility of chemical oxygen demand index as an application for calculations of several parameters of surface water quality, which are oxidized during a chemical oxygen demand determination.Validerat; 20101217 (root
