Assessment of photochemical processes in marine oil spill fingerprinting

Synthetic zeolites from fly ash as effective mineral sorbents for land-based petroleum spills cleanup

“…Mechanical, biological and photochemical methods are used for the removal of petroleum products [11][12][13][14], among which the mechanical methods involving solid adsorbents have been identified as the most effective [15,16]. Adebajo et al [17] distinguished three groups of adsorbents: synthetic mineral products, synthetic organic products and natural materials.…”

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

“…Oil is generated through diagenesis of its source organic matter resulting on a final product composed of a myriad of relatively non-polar components with great diversity of structures, functionalities and chemical properties such as volatility, solubility and polarity (Tissot and Welte, 1984). Over a million metric tons of crude oil are released into the marine environment annually from accidental oil spills, industrial/municipal sources, marine transport and natural oil seeps (Radovic et al, 2014). Oil released into the sea will produce heterogeneous and diversified mixtures of dissolved hydrocarbon constituents and undissolved oil residues such as oil droplets with different physical/chemical properties which can be affected by a wide range of environmental factors.…”

Evaluation of diagnostic ratios of medium and serious weathered oils from five different oil sources

“…Molecular markers and diagnostic indices including n-alkanes, isoprenoid hydrocarbons, polycyclic aromatic hydrocarbons, as well as steroidal terpenes compounds can provide specific information on its chemical composition and be linked to the suspected source (Wang et al, 1994(Wang et al, , 1999Kvenvolden et al, 1995;Stout et al, 2001;Wang et al, 2013) and widely used in oil spill studies (Peters et al, 2005;Wang et al, 2006;Liu et al, 2009;Radović et al, 2014).…”

“…Many studies on biomarker indicators in short term weathering processes were involved Zhao et al, 2008;Sun et al, 2009;Lemkau et al, 2010;Radović et al, 2014). In contrast, few studies pay attention to medium and long-term weathering laws through weathering experiments in China.…”
