چکیده | ||
The decrease in the level of industrial production and the significant reduction of highly toxic substances used in the agriculture of the Volga region in the last decade did not maintain the expected decrease of pollution level in the Volga water. Concentration of many polluting substances in water continues to remain high. Among the numerous polluting substances in the Volga River two groups of highly toxic substances are significant: Its chlorine organic pesticides and the heavy metals having high stability and accumulative effect. The purpose of the research was to determine the most dangerous sources of pollution of a water ecosystem and the level of the Delta Volga River,as well as the ways of their migration and the amount of the toxic influence in the waters life.
