“…Pristane and phytane, both branched aliphatic hydrocarbons, were also analyzed. Even though the pristane and phytane are degradable (Le Dreau et al, 1997), they have been used as indicators of weathered petroleum residues (Tran et al, 1997). Values for both n-C 17 /pristane and n-C 18 /phytane were comparable in most of our samples.…”

“…However, a significant difference was observed when another diagnostic ratio, AHCs/C 16 (ratio of total alkanes and C 16 ), was used. As n-C 16 is rarely found in biolipids, the ratio of AHCs/C 16 is usually high (i.e., 50) for biogenic materials compared to relatively low values (i.e., 15) in petroleum-contaminated samples (Tran et al, 1997).

Surficial sediment samples collected from Kaohsiung Harbour and its nearby coast were analyzed for aliphatic hydrocarbons and parent polycyclic aromatic hydrocarbons (PAHs). According to our results, the average total concentrations of n-alkanes (n-C12 to C35) and aromatics (15 PAHs) were 4.33 microg g(-1) dry weight (ranged 0.46-22.60) and 0.59 microg g(-1) dry weight (ranged 0.09-1.75), respectively. The highest concentrations of aliphatic and aromatic hydrocarbons were recorded in stations near the estuaries of Qianzhen River and Love River, respectively. Aliphatic hydrocarbons in the samples indicate that there has been significant non-petrogenic, possibly terrestrial, contribution in the sediment of the open coast of Kaohsiung Harbour and that there has been dominant contribution from petrogenic sources in the sediment of the inner harbour. PAHs, detected in the samples, however, indicated a higher pyrolytic contribution in open-coast samples and a higher petrogenic contribution in the inner harbour. Overall, sediment concentrations of total alkanes in this study were comparable to those found in Victoria Harbour, Hong Kong and are higher than those found in Xiamen Harbour, China. Concentrations of total PAHs in inner Kaohsiung Harbour sediments were relatively lower than those found in Victoria Harbour, Hong Kong and Xiamen Harbour, China, but comparable to those found in Hsin-ta Harbour, Taiwan and Incheon Harbour, Korea. In comparison with several effect-based sediment quality guidelines, most PAH concentrations found in samples taken from inner harbour stations exceeded the Threshold Effect Level of Florida indicating a slight possibility of adverse effects.

“…The ratio is usually close to 1 in petroleum products, higher in plankton and benthic algae, and lower in higher plants (Tran et al, 1997). Additionally, the contamination of petroleum derivatives rich in low or high molecular weight hydrocarbons can interfere with LMW/HMW values (de Oliveira and dos Santos Madureira, 2011).…”

“…Moreover, aliphatic hydrocarbon composition analyzed by gas chromatography (GC) can provide information on petroleum sources and degradation. The ratio of low-to high-molecular-weight compounds (LMW/HMW), carbon preference index (CPI), the ratio of pristane to phytane (Pr/Ph), and the C 16 ratio of petrogenic hydrocarbons are significantly different from those of biogenic hydrocarbons (Cincinelli et al, 2008;Guo et al, 2011;Harji et al, 2008;Medeiros and Bicego, 2004;Tran et al, 1997). Additionally, various oils and their products (gasoline, fuel oil, motor oil, and so on) have different chromatographic distributions of aliphatic hydrocarbons (Abdullah, 1997;Latimer and Quinn, 1998).…”

“…In addition, the knowledge about the composition of n-alkanes in fossil organic matter enabled the use of the n-alkane distribution in solving environmental problems, too (e.g. regular Matsumoto 1982;Colombo et al 1989;Theobald et al 1995;Wang et al 1995;Tran et al 1997;Rogers and Savard 1999). The identification of oil-type pollutants in soil, alluvial sediments, groundwaters, and in recent formations in general, is enabled by the fact that, in most cases, n-alkanes in oil are present in greater amounts and with different distributions than in extracts of recent sediments.…”

Investigations presented in this paper were aimed at defining the alterations of n-alkane composition in cases of oil-polluted alluvial sediments. Therefore, oil-polluted groundwater samples, taken in five different time intervals during a period of 28 months, were investigated. Samples of alluvial sediments were taken from two boreholes within an oil refinery at Pancevo, Yugoslavia. In both boreholes significant alterations with characteristic degradation of "oil" n-alkanes with no odd-or even-member predominance were observed, as well as subsequent synthesis of new ones with pronounced even-member predominance, and with maxima at C 16 and C 18 . Since no additional contamination of boreholes was observed by analyses of steranes and triterpanes, the observed changes can only be attributed to microbial activity. It is assumed that for the degradation of oil n-alkanes, as well as for the synthesis of "new" n-alkanes, algae such as dinoflagellates are responsible. This assumption was confirmed by identification of n-alcohols with even-member predominance (C 14 -C 20 ), by identification of cholesterol, as well as of n-fatty acids with even-member predominance (C 14 -C 18 ) in the extract with n-alkane even-member predominance.
