Abstract

The present work contains the results of water quality tests carried out in the central part of the River Leba in the years 1999-2001. Those tests consisted in defining physical and chemical content of water quality rating in the hydrographic profile of the river near the town of Lebork. From the obtained results it comes out that the concentration of nitrogen and phosphorus compounds and BOD5 values was growing in the course of the Leba flow through the town of Lebork. This town brings into the River Leba on average 2.92 million m3 of sewage during a year, out of which it falls to one inhabitant during a year: BOD5 – 3.2 kgO2; 0.36 kg of phosphorus; 4.10 kg of nitrogen. The River Leba constitutes, moreover, a significant source of pollution of the Baltic waters because every year it brings into it 1785 tons of nitrogen and 154 tons of phosphorus.


Key words: oxygen demand, phosphorus, nitrogen, agglomeration, river
