“…The densities of Location 1 and Location 2 with values of 0.8448 g/ml and 0.8227 g/ml fall within the range of 0.78-0.88 g/ml listed for light crude oils while the density of the co-mingled sample from Location 3 with a value of 0.9012 falls with the range (0.88 g/ml-10 g/ml) of crude oils designated as heavy. The density values recorded for these three crude samples agree with 0.8400 g/ml and 0.9000 g/ml reported by several authors [23,24].…”

Aim: To evaluate the concentrations of Polycyclic Aromatic Hydrocarbons and Total Petroleum Hydrocarbons in some Nigerian crude oils. Study Design: Field and Laboratory-Experimental Design were used in this study. Place and Duration of Study: Crude oil samples were obtained from three locations (designated as Location 1, Location 2, and Location 3) in the Niger Delta, Nigeria. Methodology: The samples were subjected to liquid-liquid extraction using dichloromethane and analysed using GC-FID. Results: The results of the analyses of the crude oils gave polycyclic aromatic hydrocarbons (PAHs) concentrations of 2.6089 x 104 ppm representing 60.06% and total petroleum hydrocarbon (TPH) concentration of 4.3201 x 104 ppm at Location 1, PAHs concentration of 4.764 x 103 ppm (62.8%) and TPH recording a concentration of 7.583x 103 ppm at Location 2, while Location 3 had PAHs concentration of 9.93 x 102 ppm (30.66%) and TPH concentration of 3.239 x 103 ppm. The total concentrations of the high molecular weight PAHs were lower than those of the low molecular weight PAHs in the samples. Also the concentrations of the individual PAHs were higher in the low molecular weight PAHs. The mean PAHs concentrations of 2707.6 ppm (location 1), 551.5 ppm (location 2) and 90.7 ppm (location 3) are different. Conclusion: The observed results show that all the sixteen polycyclic aromatic hydrocarbons listed as priority pollutants are present in the three crude oil samples with higher concentrations in the light crude oils than in the heavy crude oil and a strong correlation with the total petroleum hydrocarbon concentration. It was also observed that though the ratios of the low molecular weight PAHs to high molecular weight PAHs of the crude oils indicate petrogenic, the unique diagnostic ratios suggest pyrogenic input. There is therefore the need to develop a method of PAHs removal from PAHs contaminated water based on locally available and cheap materials.

“…On the other hand, the crude oil sample from Location 3 with a viscosity value of 115mPa.s which is between 50 mPa.s -50000 mPa.s can be classed as heavy crude. The viscosity range recorded for the three crudes, 5.10 mPa.s -115 mPa.s(Table 4) is in agreement with 50 mPa.s and 112 mPa.s previously reported by several authors[29,24].…”

“…Gas chromatography mass spectrometry (GC-MS) is a hyphenated analytical technique commonly used for environmental analysis due its specific and distinct monitoring capacity, especially when applied in the selective ion mode (Wang and Fingas, 1995;Brassington et al, 2010;Yang et al, 2015). The identification and characterization of petroleum compounds by GC-MS is achieved by comparing retention time and a query mass spectrum with reference mass spectra in a library via spectrum matching.…”

“…The identification and characterization of petroleum compounds by GC-MS is achieved by comparing retention time and a query mass spectrum with reference mass spectra in a library via spectrum matching. Versions of the NIST library, currently containing over 276,000 reference spectra, and search algorithms are available from all major MS manufacturers (Yang et al, 2015). Such method has been used to assess the PAHs in tar-contaminated soils (Lorenzi et al, 2010) and monitor bioremediation of PAHcontaminated soil via in-vessel composting using fresh organic waste (Zhang et al, 2011).…”

“…This will be especially marked in a heavily hydrocarbon contaminated environmental sample where there will be a large number of different PAHs (Coulon et al, 2012). HPLC techniques are applied much less, for oil-fingerprinting analysis in comparison to GC methods (Yang et al, 2015). The major disadvantage of HPLC applications for quantification is the lack of universal detector, which yields same response for all class of chemical constituents (Sarowha et al, 1997).…”

This review provides a critical insight into the selection of chromatographic and spectroscopic techniques for semi-quantitative and quantitative detection of petroleum hydrocarbons in soil and sediment matrices. Advantages and limitations of both field screening and laboratory-based techniques are discussed and recent advances in chemometrics to extract maximum information from a sample by using the optimal preprocessing and data mining techniques are presented. An integrated analytical framework based on spectroscopic techniques integration and data fusion for the rapid measurement and detection of on-site petroleum hydrocarbons is proposed. Furthermore, factors influencing petroleum hydrocarbons analysis in contaminated samples are discussed and recommendations on how to reduce their influence provided.

The main petroleum product transported through pipelines in Canada is diluted bitumen (dilbit), a semiliquid form of heavy crude oil mixed with natural gas condensates to facilitate transport. The weathering, fate, behavior, and environmental effects of dilbit are crucial to consider when responding to a spill; however, few environmental studies on dilbit have been completed. We report on 11‐d‐long experimental spills of dilbit (Cold Lake Winter Blend) in outdoor microcosms meant to simulate a low‐energy aquatic system containing natural lake water and sediments treated with low (1:8000 oil:water) and high (1:800 oil:water) volumes of dilbit. In the first 24 h of the experiment, volatile hydrocarbons quickly evaporated from the dilbit, resulting in increased dilbit density and viscosity. These changes in dilbit's physical and chemical properties ultimately led to its submergence after 8 d. We also detected rapid accumulation of polycyclic aromatic compounds in the water column of the treated microcosms following the spills. The present study provides new information on the environmental fate and behavior of dilbit in a freshwater environment that will be critical to environmental risk assessments of proposed pipeline projects. In particular, the study demonstrates the propensity for dilbit to sink under ambient environmental conditions in freshwaters typical of many boreal lakes.
