摘要：

In this study we develop a green treatment method based on supramolecular solvents (SUPRASs) made up of reverse aggregates of short/medium chain length alcohols (C6-C10) in mixtures of water and a sustainable organic solvent (methyl-tetrahydrofuran). SUPRASs ingredients have low toxicity and can be obtained from renewable sources. The new SUPRASs were characterized and its suitability for determination of oxygenated polycyclic aromatic hydrocarbons (oxy-PAHs) in food was tested. Analysis was made by liquid chromatography coupled to high resolution mass spectrometry. The method provided quantification limits in the range 0.4-4 ng g-1 with low consumption of reagents (200uL of SUPRAS per sample) and it was based on simple agitation and centrifugation without concentration/evaporation steps. All target compounds (except 11-H-benzo[b]fluoren-11-one) were found in 7 out of 19 samples, mainly in fish and seafood samples, with levels in the range n.d. - 8 ng g-1.
