Abstract The content of polycyclic aromatic hydrocarbons (PAH) from sediment layers of Bodensee areas differently exposed to environmental burden were determined. 32 PAH and 10 nitrogen containing PAH were identified by comparison with authentic samples.A method of quantitativ enrichment and gasdiromatographic determination of PAH containing 4-7 rings is described. In a comparative profile analysis only 20 most abundant PAH have been regarded.Low burdened areas (entre of the lake, 250m deep; Güttingen) show only 10 - 20% of the PAH content of high-burdened areas (mouth of Argen and Schüssen).The qualitative and quantitative composition of the PAH fraction (PAH-profile) from different layers of a sediment drilling core are very similar whereas profiles from different regions can be distinguished.The concentration of PAH increases from the surface to a layer with maximum burden (1965 - 1970) and then decreases to a remaining concentration (1900). From the typical PAH profile and some characteristic compounds as e.g. benzo (b) -naphtho (2,1-d) thiophan, benz (a/c) acridines, benzo (a/b/c)-carbazoles, dibenzacridines, and dibenzcarbazoles some potential sources as motor- car traffic, petroleum, fuel oil, and used lubricating oil can be excluded. Coal combustion smoke gas is supposed to be the main source of emission.

Used Lubricating Oil

Applied pyrolysis is used in this work as a treatment technique for hydrocarbon fraction recovery of used lubricating oils (ULO) with the aim of its further energetic valorisation. Applied pyrolysis bring also the advantage of a better management of metallic compounds that will be concentrated in the solid residue. In this work, technical parameters have been evaluated to establish their influence on the process evolution with the aim of identifying the adequate parameters for obtaining the maximum liquid fraction. It was found that, for an equilibrated energy balance, the final pyrolysis temperature should not exceed 460°C and the main parameter that affect the pyrolysis oil yield and its physical-chemical properties is the heating rate in the thermal range of decomposition. Activated Zeolites (HZSM-5 type) and Na2CO3 were used as catalysts. The catalysed pyrolysis tests were performed using direct contact between ULO and catalyst, the materials being mixed before processing. Experimental results showed that in non-catalysed pyrolysis an increasing heating rate is slightly reducing the yield of liquid fraction. On the other hand, by using catalysts, the liquid fraction is decreasing. Thus, the highest liquid ratio (81 wt.%) was obtained when the Na2CO3 is used and the process is run under a heating rate of 3-5°C/min. But then, the zeolite HZSM-5 is leading to the highest overall conversion, 95 wt.% at 15-17°C/min, and is positively influence the formation of gas fractions.

Used Lubricating Oil

Soil and surface water contamination by used lubricating oil is a common occurrence in most developing countries. This has been shown to have harmful effects on the environment and human beings at large. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 15% (w/w) used lubricating oil and amended with 10% brewery spent grain (BSG), banana skin (BS), and spent mushroom compost (SMC) was studied for a period of 84 days, under laboratory condition. At the end of 84 days, the highest percentage of oil biodegradation (92%) was recorded in soil contaminated with 5% used lubricating oil and amended with BSG, while only 55% of oil biodegradation was recorded in soil contaminated with 15% used lubricating oil and amended with BSG. Results of first-order kinetic model to determine the rate of biodegradation of used lubricating oil revealed that soil amended with BSG recorded the highest rate of oil biodegradation (0.4361 day−1) in 5% oil pollution, while BS amended soil recorded the highest rate of oil biodegradation (0.0556 day−1) in 15% oil pollution. The results of this study demonstrated the potential of BSG as a good substrate for enhanced remediation of hydrocarbon contaminated soil at low pollution concentration.
