Within the framework of the research described here, an attempt was made to identify volatile and semivolatile Non-Regulated Organic Compounds present in samples of riverine water. Twenty-five samples, collected from the Odra River during the eighth sample collection in October 2000 within the framework of the International Odra Project, have been analyzed using the PT-TD-GC-MS technique. A computerized analysis with the use of a mass spectrometer pointed to the presence of organic compounds of natural and anthropogenic origin. The concentrations of chloroorganic compounds, i.e. saturated and unsaturated aliphatic aromatic hydrocarbons and chlorinated bis-isopropyl ether, in samples of water collected near Brzeg Dolny amounted to about 1 ppb. A slightly narrower spectrum of chloroorganic compounds occurring at lower concentrations was identified in samples of water collected in Głogów. The most likely source of these compounds was the “Rokita” Chemical Plant.
