“…These sorbents are produced by polymerization of monomers in the presence of a specific molecule that acts as a template. The obtained polymer will have plenty of holes that perfectly match the compound used as a template, which usually is the same (or structurally similar) as the target molecule (Ncube, Madikizela, Cukrowska, & Chimuka, 2018). The extraction process could be considered as the equivalent to a SPE in a cartridge.…”

Polycyclic aromatic hydrocarbons (PAHs) are food contaminants whose presence in foodstuffs is especially alarming due to their carcinogenic character. These substances are highly lipophilic and thus, unsafe levels of these compounds have been found in edible fats and oils. Efficient methodologies to determine such molecules in lipidic matrixes are therefore essential. In this review, a detailed description of the analytical methods for the determination of PAHs in vegetable oils from the last 15 years has been provided. Particular emphasis has been placed on innovative sample treatments, which facilitate and shorten the pretreatment of the oils. Finally, results from recent investigations have been reviewed and studied in depth, in order to elucidate which PAHs are most commonly found in vegetable oils.

“…Until now, a plethora of publications discuss the different analytical procedures for the extraction of PAHs from liquid, solid and air matrices [22][23][24][25][26][27][28][29]. To the best of our knowledge, in the last five years there were no review papers regarding the extraction techniques of PAHs from environmental samples with the novel miniaturized extraction and microextraction techniques.…”

Polycyclic aromatic hydrocarbons (PAHs) comprise a group of chemical compounds consisting of two or more fused benzene rings. PAHs exhibit hydrophobicity and low water solubility, while some of their members are toxic substances resistant to degradation. Due to their low levels in environmental matrices, a preconcentration step is usually required for their determination. Nowadays, there is a wide variety of sample preparation techniques, including micro-extraction techniques (e.g., solid-phase microextraction and liquid phase microextraction) and miniaturized extraction techniques (e.g., dispersive solid-phase extraction, magnetic solid-phase extraction, stir bar sorptive extraction, fabric phase sorptive extraction etc.). Compared to the conventional sample preparation techniques, these novel techniques show some benefits, including reduced organic solvent consumption, while they are time and cost efficient. A plethora of adsorbents, such as metal-organic frameworks, carbon-based materials and molecularly imprinted polymers, have been successfully coupled with a wide variety of extraction techniques. This review focuses on the recent advances in the extraction techniques of PAHs from environmental matrices, utilizing novel sample preparation approaches and adsorbents.

“…Polycyclic aromatic hydrocarbons (PAHs) refer to the compounds composed of two or more benzene rings obtained by high temperature in a linear, angular or string arrangement [1]. Those compounds have great environmental hazards such as carcinogenesis, mutagenicity, and distortion, which has been significantly released into the environment with human activities [2][3][4][5]. The adsorption onto sediment is one of the main retention behaviors of PAHs in the environment because of its high hydrophobicity [6][7][8].…”

We investigated the adsorption of phenanthrene (PHE) onto estuarine sediment with varied salinity and concentrations of anionic surfactant (sodium dodecyl benzene sulfonate, SDBS). It is a critical step for better understanding of the migration of polycyclic aromatic hydrocarbon (PAH) pollutants to seawater. The concentration of PHE in the experimental system was detected by a fluorescence spectrophotometer and the results were expressed by partition coefficient (in terms of K d ). It found that the salinity promoted and the SDBS inhibit the adsorption of PHE onto sediment in a single system. The combination effect of SDBS and salinity enhance this adsorption behavior but varied significantly with the ratio of salinity to surfactant. It is a confirmed fact that the mobility of phenanthrene in water increased with the combination of the salinity and SDBS. It would lead to the pollution of PHE change from point model to mobility model and increase its flux into the sea. However, the mechanism of those adsorption behaviors is unclear and may relate to the interactions between sediment and SDBS, SDBS and salinity, and sediments and salts, which need further study.
