Aim of this study was to assess quality of the Danube sediment from the water source "Ratno Ostrvo", which is in the vinicity of the Oil Refinery "Novi Sad" (Serbia, Yugoslavia), after bombardment of ...the refinery in 1999. In the period March-October 2000, sediment samples were analysed for their oil and oil-derivates contents, i.e. mineral oils contents, by quantitative IR-spectrophotometry, and by qualitative and quantitative GC/MS analyses for their polycyclic aromatic hydrocarbons (PAH) contents. Oil pollution was detected in sediment samples.
The organic ("bitumen") fraction content was determined in samples of the "Barje" water reservoir sediments (Serbia, Yugoslavia). A classical organic-geochemical method for sediment analysis was ...applied: Soxhlet extraction was applied for the isolation and determination of the "bitumen" fraction; the group content was determined by column chromatography and the isolated alkaline fraction was analyzed by GC analysis. On the basis of group composition results, as well as on the basis of the distribution of n-alkaline homologues it was concluded that the examined sediments represent unpolluted environmental samples, at least as far as oil-type pollutants are concerned.
