Expeditional Hydrochemical Researches of Black Sea Coastal Zones and Kerch Strait in 2007-2008

Abstract

Analysis results, obtained during the expeditionary researches along the Russian Black Sea coast in 2007-2008, showed that significant increase of the biogenic matters in the coastal zone in comparison with the sea zone is usually observed at the confluence of rivers, in cities and in the ports. The main critical zones of ecological risk in the Black Sea are formed in the places of river runoff influence. With the recreational load on beaches and coast the increase of biogenic matters in the sea waters of littoral zones occurs, the cases of unfavorable treatment on dissolved oxygen are observed, the contamination level tendency stabilization of sea inshore waters is preserved.
