Sulfur Compounds in Petroleum Hydrocarbon Streams

Determination of concentrations of sulfur compounds in different petroleum samples is a true analytical challenge. Only analytical procedures based on gas chromatography can meet the sensitivity and accuracy requirements dictated by up-to-date petroleum industry. The objective of this work is to develop the method for the quantifying of sulfur compounds in petroleum hydrocarbon streams. The opt...

Bioremediation of petroleum hydrocarbon contaminants in marine habitats.

Bioremediation is being increasingly seen as an effective, environmentally benign treatment for shorelines contaminated as a result of marine oil spills. Despite a relatively long history of research on oil-spill bioremediation, it remains an essentially empirical technology and many of the factors that control bioremediation have yet to be adequately understood. Nutrient amendment is a widely ...

Investigation of Hydrocarbon-degrading Microbial Communities of Petroleum Hydrocarbon Contaminated Soils in Harghita County, Romania

Microorganisms able to degrade hydrocarbon pollutants (gasoline, and other petroleum derivatives) have been isolated from two contaminated areas (Sândominic and Bălan) by enrichment technique. The hydrocarbon degradative capacity of contaminated sites were determined using “Biometer flasks” (respiratory CO2 production measurement). Total counts and hydrocarbon degrading counts were determined u...

Fish Bile as Biomarker of Total Petroleum Hydrocarbon Pollution in the Khure Mussa – Persian Gulf

Total Petroleum Hydrocarbon ( TPH ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. TPH are readily transformed into more hydrophilic metabolites, which are accumulated in bile. Thus fish bile can be used as a biomarker of exposure of fish to TPH in the marine environment. in this study several stations were se...
