This paper show the results of investigation of concentration of odorous chemical compounds emitted upon ageing of anaerobically stabilised biosolids that could contribute to the overall odour character of nuisance emissions. Biosolids samples from wastewater treatment plant were collected in spring time. Concentrations of volatile organic compounds using a US EPA flux hood and Proton Transfer Reaction-Time of Flight-Mass Spectrometry technique were monitored during three weeks. The concentrations of identified odorants were estimated from 0.23 ppm to 2.93 ppm. Increasing concentrations of all identified compoundswere observed after 10th day fromthe sampling days for two samples. It can be a consequence of biological process occurring in threeweek time in biosolids cakes.
