“…The extraction of PAHs from atmospheric PM can be achieved with a number of established methods [11,12]. Microwave-assisted extraction (MAE) provides a technique where compounds can be extracted selectively, in a relatively short period of time compared to conventional extraction methods and allows for an enhanced extraction yield for the more volatile compounds which normally require special and separate extraction methods [13,14].…”

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 .

“…Because PAH-specific samplers were not deployed, we assayed some of the most hazardous four-to six-ring PAHs in 243 of the archived PM 2.5 filters described above, by using a method we developed for this purpose (26). Briefly, the Teflon filters were extracted with 10 ml of dichloromethanecontaining deuterated PAHs as internal standards.…”

“…Thirteen PAH species, ranging from 3 to 6 rings, were analyzed using an Agilent Technologies (Palo Alto, CA) system consisting of a 6890N GC, 5973N MS, with an autoinjector as de-scribed [24]. Limits of PAH detection were approximately 5 pg on line.…”

Biodiesel, an alkyl ester of plant oils that can be used in an unmodified diesel engine, is the first renewable diesel fuel alternative to become a commercially accepted part of our nation's energy infrastructure. For traditional diesel fuel exhaust, it has been demonstrated that the particulate matter (PM) organic components play a role in acute inflammatory reactions. However, there have been only a few cytotoxicity and mutagenicity studies on biodiesel emissions. In this study, BEAS-2B cells, a transformed human airway epithelial cell line, were exposed in vitro to the PM organic extracts from Standard Reference Material (SRM) 1975, soy ethyl ester (SEE), soy methyl ester (SME), and petroleum diesel for 24 hours. This study demonstrated that the organic extracts of biodiesel PM in an aqueous solution can increase the release of pro-inflammatory cytokines IL-8 and IL-6 by respiratory epithelial cells. On a microgram PM equivalent per ml (μg PM eq/ml) basis, exposure to biodiesel extracts was associated with a greater release of IL-8 and IL-6 relative to organic extracts of two diesel PM samples. The dose range tested was not cytotoxic. It was also noted that the solvent exchange method, which was used to prepare the aqueous exposure doses, may not be appropriate for the investigation of biodiesel extracts, though it has been used extensively in petroleum diesel research. A valuable new finding from these experiments is that the soluble organic fraction (SOF) of biodiesel PM begins to elicit a cytokine response in BEAS-2B cells at an exposure lower than petroleum diesel PM extract (approximately 40 μg PM eq/ml). However, more research is required to better characterize the potency of the organic fraction of biodiesel compared to petroleum diesel.
