“…A comparison of some of the traditional and instrumental extraction techniques used on polycyclic aromatic hydrocarbons (PAHs), PCBs and pesticides ( Fig. 1) shows that selecting the optimum extraction technique is no simple matter [61]. Those most commonly used have been the conventional Soxhlet method and solid -liquid shake-flask extraction, which require huge amounts of chlorinated solvents.…”

“…For this reason, alternative instrumental strategies have been suggested for the extraction of these compounds in complex matrices. The first technique of this kind to appear was SFE which was initially plagued with a number of different instrumental problems related to pressure regulation and investment costs [61,64,65]. Labs that work with certified quality systems only use methods that have been approved by the EPA or which have been suitably validated.…”

“…In this case, solid -liquid extraction would have to be ruled out. SFE has been included in some of the EPA's reference methods for the extraction of pollutants (method 3562 for PCBs extraction, 3561 for PAHs extraction and method 3560 for total petroleum hydrocarbons extraction) [13,61,64,65]. However, it is also necessary to validate SFE methods with reference materials and comparing them with official EPA-approved methods and with other extraction techniques.…”

“…However, it is also necessary to validate SFE methods with reference materials and comparing them with official EPA-approved methods and with other extraction techniques. Despite the many advantages of SFE which include simultaneous clean-up and extraction (see Section 4) in only 30 -60 min, the interest in this technique has waned over the course of the past decade in various analytical fields [61,64,65].…”

ReviewSupercritical fluid extraction of polyhalogenated pollutants from aquaculture and marine environmental samples: A review This article focuses on the state-of-the-art in sample preparation using supercritical fluid extraction (SFE), to monitor the content of polyhalogenated pollutants in aquaculture and marine environmental samples. Marine sediments and biological applications, including several types of samples matrices (fish, shellfish, seaweed and fish feed) and analyte groups (polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), polybrominated diphenylethers (PBDEs), polychlorinated dibenzop-dioxin (PCDD)/Fs and organochlorinated pesticide (OCPs)) are discussed with respect to SFE use and optimisation of conditions. We also discuss the great analytical potential of SFE, the integration of the extraction and clean-up steps for rapid sample processing justifying its use for routine work. The most recent SFE applications to the determination of these pollutants in marine environmental (biota and sediment) samples, published in the last 15 years, are reviewed.

The extraction stage is considered to be a key step of most analytical strategies, as it greatly influences the type and quality of analytical data. In case of plants, which are interesting materials for a broad range of domestic or industrial‐scale applications, extraction is a particularly crucial step as solid samples are considered most of the time. Indeed, extractions from solids are well known to be more critical than from liquids, owing to limitations by diffusion and/or strong solute–solid interactions; solutes may also be trapped into cells within the plant materials. Consequently, careful knowledge about the plant material itself (its structure and composition) and whenever possible about the compounds to be extracted (their expected levels, polarity, and stability) is of great help for conceiving and optimizing an extraction process; the fate of the extract is also important to consider, as the selectivity expected for the extraction differs between target and fingerprint approaches. Practically, even though several extraction techniques are available, none is the best and should be recommended for any application. However, the use of recent techniques should be favored, as they reduce both the solvent volume and the time required for the extraction; the hyphenation or combination of techniques should be investigated to take benefit from the advantages of several techniques.
