Influence of the Rezina-Rybnitsa Industrial Complex on the Content of Mercury (II), Copper (II), Lead (II), and Cadmium (II) in the Dubossary (Dubasari) Reservoir of the Dniester (Nistru) River

摘要

The contents of mercury (II), copper (II), lead (II), and cadmium (II) in abiotic components of the environment (water, suspended matter, bottom deposits) of the Dubossary (Dubasari) Reservoir on the Dniester (Nistru) River, Republic of Moldova, was studied in 2000-2001. It has been demonstrated that the maximal concentrations of the metals under study were in the area comprising the Rezina-Rybnitsa industrial complex that produces 4.4 million tons of cement and 0.7 million tons of metal annually. In this area, the contents of studied metals in the soil exceed the background level 2-11 times. The metals are transferred into the reservoir in the dissolved and suspended forms with atmospheric precipitate.
