Odra river

A procedure of this kind was used in the International Odra Project—IOP (1997-2001).113 Screening tests of water samples on V. fischeri bacteria showed that samples taken from two measuring stations (the town of Brzeg Dolny and the confluence of the Mala Panew River with the Odra River, Poland) were toxic toward the bacteria. Chemical analysis for the detection of organic...

The presence of HHCB and AHTN in fish and mussels was confirmed by enantioselective analysis (Franke et al., 1999). In the same study, the authors reported the occurrence of a transformation product of HHCB, the HHCB-lactone, found in Odra river and Elbe river water (Germany).

The Czech Republic is a landlocked state lying in the middle of a mild band of the northern hemisphere in the centre of Europe. The Czech Republic has state borders with Poland, Germany, Austria and Slovakia. The total length of the state borders is 2290 km, of which 738km are defined by rivers - the so-called wet border . The territory of the Czech Republic is on the basins of three important European rivers - the Elbe, the Odra and the Morava (Danube), dividing the basins of the North Sea, the Baltic and the Black Sea. The Orlice River is one of the rivers which composed the Elbe River basin.

The concentrations of lead in the river waters in the Czech Republic are shown in Table 13. According to the lead characteristic concentration (90th percentile), the most of the observed surface water in the Czech Republic belongs to the purity class I except for Sazava-Pikovice, Otava-Pisek, Svratka-Vranovice (class II) and Bi lina-Usti nad Labem, Odra-Bohumm, Olse-Vefnovice (class III) (Ministry of the Environment of the Czech Republic, 1998).
