Abstract:

The aim of the investigations was to estimate the half-life of selected PAHs in sewage sludge. Five hydrocarbons selected from 16 PAHs- EPA were chosen. In this study, the quantity changes in the concentration 3- and 4-ring of PAHs in sewage sludges were investigated. Sewage sludges were stored under aerobic conditions for 12 weeks. At the same time the sewage sludges with the added sodium azide, in order to deactivate the microorganisms (abiotic samples), were also stored. Gas chromatography-mass spectrometry was used to qualify and quantify PAHs in 2-week intervals. Sewage sludges were taken from a municipal wastewater treatment plant. Under experimental conditions the half-lives of individual compounds were diversed. In biotic samples halflife of hydrocarbons was in the range of 19 to 368 days. Half-life of PAHs in abiotic sewage sludges was in the range of 31 to 2961 days. The most persistent were phenanthrene.
