Distribution of pollutants in the Odra River system. Part II. Organic pollutants in Odra River water

Within the framework of the International Odra Project, organic pollution (pes­ti­cides, volatile organic compounds, poly­cy­clic aromatic hydrocarbons, polychlorinated bi­phe­nyls, chlo­roben­zenes) of the Odra river and its tributaries were studied by a team from Gdask University of Technology. From August 1997 to May 2000 seven sample collections were conducted, i.e. one directly after the flood in 1997 (for sampling sites see map in Part I). During the study period the pollution of Odra river water with PAH, PCBs and pes­ti­cides in general did not exceed allowable levels. The highest concentration of volatile chloroorganic compounds was found in the sample from Brzeg Dolny.
