“…The digests were filled to a volume of 50 ml with ultra-pure water, decanted from undissolved solid residues, and diluted ten-fold again prior to measurement. Measurements were performed according to Walkner et al (2017) using an Agilent 8800 Triple Quadrupole ICP-MS (Agilent Technologies, Tokyo, Japan), using either O 2 or NH 3 (10% in He) as reaction gases in order to remove polyatomic interferences on some of the m/z used. A total of 40 elements were quantified using aqueous multi-element standard solutions for external calibration.…”

“…A total of 40 elements were quantified using aqueous multi-element standard solutions for external calibration. In addition to the 25 elements covered by Walkner et al (2017), REEs and yttrium were included; these additional analytes were measured without reaction gas. In order to check for precision and accuracy of the results, certified reference material NIST 1634c (trace elements in fuel oil) was analysed along with the samples.…”

Oil seeps from the southern Gulf of Mexico can be regarded as natural laboratories where the effect of crude oil seepage on chemosynthesis‐based communities and carbonate precipitation can be studied. During R/V Meteor cruise 114 the seep sites UNAM (Universidad Nacional Autónoma de México) Ridge, Mictlan Knoll and Tsanyao Yang Knoll (Bay of Campeche, southern Gulf of Mexico) were investigated and sampled for authigenic carbonate deposits containing large amounts of liquid oil and solid asphalt. The δ13C values of individual carbonate phases including: (i) microcrystalline matrix aragonite and calcite; (ii) grey, cryptocrystalline to microcrystalline aragonite; and (iii) clear, fibrous aragonite cement, are between −30‰ and −20‰, agreeing with oil as the primary carbon source. Raman spectra reveal that residual heavy oils from all sites are immature and most likely originate from the same reservoir. Geochemical batch modelling using the software code PHREEQC demonstrates how sulphate‐driven oxidation of oil‐derived low‐molecular to high‐molecular weight hydrocarbons affects carbonate saturation state, and shows that the oxidation state of carbon in hydrocarbon compounds and oxidation rates of hydrocarbons control carbonate saturation and precipitation at oil seeps. Phase‐specific trace and rare earth element contents of microcrystalline aragonite and calcite, grey cryptocrystalline aragonite and clear aragonite were determined, revealing enrichment in light rare earth elements for grey aragonite. By comparing trace element patterns of carbonates with those of associated oils, it becomes apparent that liquid hydrocarbons constitute an additional source of trace metals to sedimentary pore waters. This work not only demonstrates that the microbial degradation of oil at seeps may result in the precipitation of carbonate minerals, it also elucidates that trace metal inventories of seep carbonates archive diagnostic elemental patterns, which can be assigned to the presence of heavy hydrocarbons in interstitial pore waters.

“…Inductively coupled plasma techniques such as inductively coupled plasma mass spectrometry (ICP–MS) and inductively coupled plasma optical emission spectroscopy (ICP–OES) have been widely used for trace element determination in petroleum samples, such as crude oils, automotive fuels and lubricating oils, owing to their low detection limits as well as their fast multielement capability (Sánchez, Todolí, Lienemann, & Mermet, ; Walkner, Gratzer, Meisel, & Bokhari, ). ICP–MS is considered a powerful technique because it enables both accurate trace element analysis and isotopic measurement.…”

“…Microwave-assisted digestion (MW-AD) is the preferred choice (Heilmann, Boulyga, & Heumann, 2009) or even the use of a highpressure digestion system. This is more time-consuming than MW-AD but allows more complete decomposition of organic compounds owing to the high temperature and pressure used (Walkner et al, 2017).…”

A method for digestion of light and medium Iraqi crude oils (Basrah and Khanaken oils) using microwave‐induced combustion (MIC) in closed vessels is described for the determination of Hg, Au, Cu, Al, Ca, Co, K, Mg, Si and Sr by inductively coupled plasma optical emission spectrometry (ICP–OES) and Mo, Ti, Mn, Li, Se−1, Rb, Ag, Ba, Pb, As, Cd, Cr, Fe, Ni, V and Zn by inductively coupled plasma mass spectrometry (ICP–MS). Upon using MIC it was possible to obtain lower limits of detection by ICP–MS and also by ICP–OES compared with those obtained by microwave‐assisted digestion. The MIC was the best choice with regard to the possibility of using dilute nitric acid as an absorbing solution, which is important to minimize the interference encountered by ICP–MS and ICP–OES.The physicochemical parameters and some contaminants of crude oil samples were analyzed to classify and assess the quality of the crude oils. This study determines the viability of the use of Fourier transform infrared spectroscopy as an alternativee to traditional petroleum geochemical methods for crude oil characterization. The infrared fingerprints agree with the results obtained from GC–MS analysis.
