“…The overall mean recoveries obtained at 5, 10, 15, and 20 min were 74.9 l 8.7, 85.5 l 4.3, 92.3 l 5.0, and 90.5 l 5.9%, respectively. Although the extraction time of 15 min provided the maximum global value, the recovery reached using 20 min for naphthalene, which is the PAH more difficult to extract, was significantly higher and in agreement with other authors that applied other extraction techniques [36,37]. Therefore, and since acceptable recoveries for the remaining compounds were attained, 20 min was selected as optimal time.…”

A methodology based on microwave-assisted extraction (MAE) and LC with fluorescence detection (FLD) was investigated for the efficient determination of 15 polycyclic aromatic hydrocarbons (PAHs) regarded as priority pollutants by the US Environmental Protection Agency and dibenzo(a,l)pyrene in atmospheric particulate samples. PAHs were successfully extracted from real outdoor particulate matter (PM) samples with recoveries ranging from 81.4 l 8.8 to 112.0 l 1.1%, for all the compounds except for naphthalene (62.3 l 18.0%) and anthracene (67.3 l 5.7%), under the optimum MAE conditions (30.0 mL of ACN for 20 min at 1108C). No clean-up steps were necessary prior to LC analysis. LOQs ranging from 0.0054 ng/m 3 for benzo(a)anthracene to 0.089 ng/m 3 for naphthalene were reached. The validated MAE methodology was applied to the determination of PAHs from a set of real world PM samples collected in Oporto (north of Portugal). The sum of particulate-bound PAHs in outdoor PM ranged from 2.5 and 28 ng/m 3 .

“…Thus, 9% of acetone is the optimal concentration for the preconcentration of 2-6-ring PAHs. This concentration is equal or less than that reported in previous reports (10% or 25% IPA, 20% acetone) on silica-based materials [32][33][34], which is beneficial to reduce costs. In contrast, it is greater than that published in a previous report on MgO microspheres (5% acetone) [6].…”

“…As a consequence, an organic solvent, such as methanol [30], ACN [31], acetone [6,32] or IPA [33], is usually added to the sample to increase their solubility. Meanwhile, the organic solvent is frequently sought as a modifier.…”

“…Meanwhile, DCM was used for eluting PAHs from C18-MgO cartridges, owing to its superior or comparable performance [6,31,32]. To achieve a complete elution, elution volume was optimized in absence of organic modifier (see Fig.…”

“…PAHs retained on the cartridges are usually eluted with organic solvents, such as ACN [34], tetrahydrofuran [35], acetone [36], hexane [6,32], DCM [6,31], ethyl acetate [6,37] or mixtures of them [36]. Correspondingly, the resulting recoveries will change significantly with the variation of eluting solvents.…”
