This Volume presents methods for analysing and quantifying petroleum, hydrocarbons and lipids, based on their chemical and physical properties as well as their biological effects. It features prools for extracting hydrocarbons from solid matrices, water and air, and a dedicated chapter focusing on volatile organic compounds. Several approaches for separating and detecting diverse classes of hydrocarbons and lipids are described, including: (tandem) gas chromatography (GC) coupled with mass spectrometry (MS) or flame-ionisation detection, Fourier-transform induction-coupled-resonance MS, and fluorescence-based techniques. The book details high-performance liquid chromatography MS for microbial lipids, as well as a combination of techniques for naphthenic acids. Two chapters focus on quantifying bioavailable hydrocarbon fractions by using cyclodextrin sorbents and bacterial bioreporters, respectively, while a closing chapter explains how compound-specific stable-isotope analysis can be used to measure the fate of hydrocarbons in the environment.
