Abstract
The results of some hydrochemical and hydrobiological studies of the Volga River delta are presented, the temporal and spatial dynamics of the content of hydro-hydrological, hydrochemical parameters is given. The composition of macrophyte indicators in water objects in accordance with Pantle – Bukk’s method is studied; it gives an indication of the ecological state of aquatic ecosystems. The hydrochemical analysis of aquatic ecosystems showed that the content of toxic substances in urban streams to some extent is higher than the background value. Among the investigated toxicological indicators in the reservoirs of urban environment in order of priority there are petroleum products > amount of heavy metals (Pb, Zn, Cu) > detergents. Compared with aquatic complexes urban agglomeration water objects of Astrakhan Reserve did not feel great an-thropogenic impact.
