River Amur pollution with the heavy metal ions and methods of their determination

Specific character of the river Amur pollution is due to the system of nature management, man-caused effects, climatic and landscape peculiarities of the basin area. Amur pollution with heavy metals is bound to the wastes of the enterprises of fuel industry and the objects of housing and communal services. To determine the content of heavy metals in natural waters high-sensitive methods are used: atomic emission spectroscopy; atomic absorption spectroscopy; and inversion voltamperometry with chemical modified electrodes. Modern approaches to the estimation of the surface waters quality provides for the priority analysis of the biotic complex state, studying its response on the change of the environment conditions. During last time one places emphasis on the methods of biodiagnosis. Some kinds of higher and lower plants as well as microorganisms can be used as test organisms. Biotesting has a series of advantages comparing with different analytical methods of the water medium quality control.
