description: The topic of the final qualification work: âEstimation of organic impurities in river waterâ. The work is devoted to the study of the dynamics of the organic impurities in river water.Â  Tasks that were solved in the course of the study: 1. Analysis of literature on the state of water bodies in the Noth-West region of Russia and settlement Toksovo, water quality indicators and features of optical express methods of water analysis. 2. Sampling and analysis of water samples of River Toksa at five locations during the year to study seasonal and spatial variation of its characteristics: concentration of total organic carbon (TOC), total inorganic carbon (IC), total nitrogen (TN), Optical Density at 254 nm (OD254), fluorescence intensity (I), specific electrical conductivity (SEC) 3. Describe informativity of optical characteristics in estimation of organic matter in river water. The study showed the relevance of using optical methods of water density as express methods. The data obtained as a result of the application of optical analysis methods were confirmed by the data obtained as a results of laboratory studies.
