Indication of maintenance of hydrochemical pollyutant in the rivers of South Ural on an index of occurrence of mollusks from Prosobranchia subclass
The analysis of a possibility of use of mollusks from Prosobranchia subclass for biological indication of chemical pollution of waters is provided in article during environmental monitoring of the rivers of South Ural. From 2005 to 2016 dynamics of occurrence of 6 species of mollusks from Prosobranchia subclass in regions of 17 state water posts which are on the rivers of South Ural was studied. As a result of researches significant strong negative and positive correlative dependences between occurrence of a number of the studied species of gastropods with some hydrochemical parameters are revealed statistically. Thelinear regression models for the forecast of concentration of pollyutant in river waters of South Ural on occurrence of mollusks from Prosobranchia subclass are calculated.
