    The aim of this thesis was to perform the test on samples of sediments after the fermentation process in the sweage treatment plant Kraków-Płaszów as regards occurrence in this sediments paraffin and aromatic hydrocarbons. Sewage samples were collected from September to November and during March. Collected material was extracted by the ultrasonic, using petroleum ether, and then analyzed in the gas chromatograph Hewlett Packard 5890 Series II. The results were worked out and described by the basic statistical methods. The research results revealed that in the analyzed sewage sludge were present vestigial amounts of paraffinic and aromatic hydrocarbons. The exception was toluene, which dominanted in the tested compounds. Due to its neurotoxic effect, it is suggested to improve the biological purification process by using the additional strains of bacteria.
