Application of petroleum hydrocarbon chemical fingerprinting and allocation techniques after the Exxon Valdez oil spill

Polycyclic aromatic hydrocarbon fingerprints in the Pichavaram mangrove–estuarine sediments, southeastern India

“…HMW PAHs were mostly absent in the deeper (below 25 cm) and older sediments, which is consistent with the fact that there was lack of urban development in these areas before the 1970s (Kathiresan, 2000). Previous studies indicate that LMW PAHs and their alkyl derivatives are mostly of petrogenic origin (Boehm et al, 1997;Christensen and Bzdusek, 2005). In contrast, HMW PAHs are produced due to pyrolytic activities (Fernandes et al, 1997).…”

Chemical characterization of naturally weathered oil residues in the sediment from Yellow River Delta, China

“…Hence it is very important to understand the relationship between the weathering processes and the composition changes. In recent years, numerous studies concerned with the origin, type, fate and behavior of spilled oils in aquatic environments have been reported (Hostettler et al, 1992;Bence et al, 1996;Boehm et al, 1997;Barakat et al, 2001;Prince et al, 2002;Wang and Fingas, 2003;Wang et al, 2004;Malmquist et al, 2007). However, less is known about the long-term fate of oil spilled in the terrestrial environments (for example, in contaminated soil of this study), which may not only contribute to tracking spilled oils, but also offer some guidance for oil spill bioremediation in terrestrial environment.…”

Physical and Chemical Characterization of Crude Oil-Water Mixtures: Understanding the Effects of Interfacial Process to Chemical Bioavailability

“…Crude oil is a complex mixture containing thousands of compounds from several different chemical classes with a large variety in physicochemical properties (Boehm et al, 1997). The chemical composition of crude oils is generally divided into four classes of chemical groups on the basis of their characteristics.…”
