Abstract:

This article compares the two streams: small river Elykovo (Khanty-Mansiysk) and a large Tura River (south of the Tyumen region). To compare the results of the factor analysis are used for hydro-chemical parameters of river water, as well as of the reaction to the test objects. As the test objects used such aquatic organisms as great ramshorn (P. corneus). Conducting correleation analysis was based on studies of the 4-year period from 2009 to 2012. Revealed similarities as biological and chemical parameters. Detect specific biological response to pollution for each river. Suggested the contribution of certain types of man-made interference with the overall picture of river pollution. Contribution of agents estimated at ethological reactions (moving activity, feeding activity) and physiological (survival rate, weight gain, fertility) and biochemical (carotenoid concentration) levels. Experiments were evaluated as acute and chronic effects.
