“…Limits of detection (LOD) listed in Tables 2 and 3 correspond to an amount of 6-100 pg of the investigated nitro-PAH in the analyzed sample aliquot. They are similar to the LOD obtained in earlier HPLC-reduction-fluorescence studies using the same [25,26] or different catalyst materials like Pt/Rh [21,22] or Zn [46]. In those studies, however, only 1-9 compounds were separated and detected.…”

“…After derivatization, GC-MS with electron impact ionization (EI) has also been applied successfully [16,17]. Alternative methods include high performance liquid chromatography coupled to electrochemical, chemiluminescence, and fluorescence detection [18,19,20,21,22]. Recently, the determination of underivatized nitro-PAH by low-temperature luminescence has been reported [23].…”

Polycyclic aromatic hydrocarbons (PAH) and their nitrated derivatives (nitro-PAH) are environmental pollutants which pose a threat to human health even at low concentration levels. In this study, efficient analytical methods for the analysis of nitro-PAH and PAH (extraction, clean-up, chromatographic separation, and spectrometric detection) have been developed, characterized, and applied to aerosol samples. The separation and quantification of 12 nitro-PAH was carried out by reversed-phase high performance liquid chromatography (HPLC), on-line reduction, and fluorescence detection. The detection limits were in the range of 0.03-0.5 microg L(-1) (6-100 pg in the investigated sample aliquots), and the recovery rates from soot samples were 70-90%. Nitro-PAH and PAH concentrations have been determined for different types of soot and for urban, rural, and alpine fine air particulate matter (PM2.5). For the first time, trace amounts of nitro-PAH have been detected in a high-alpine clean air environment. The on-line reduction and fluorescence technique has been complemented by atmospheric pressure chemical ionization time-of-flight mass spectrometry (APCI-TOF-MS). The MS detection allowed the analysis of partially nitrated and oxygenated PAH in laboratory studies of the heterogeneous reaction of PAH on soot and glass fiber substrates with gaseous nitrogen oxides and ozone. It led to the tentative identification of a previously unknown nitrated derivative of the particularly toxic PAH benzo[ a]pyrene (BaP-nitroquinone), and provides the first experimental evidence that PAH-nitroquinones can be formed by reaction of PAH with atmospheric photooxidants.

“…Nitro-PAHs have been determined by means of bioassay-directed fractionation and chemical analysis [29] in particulate exhaust emission of motor vehicles [5,9,10,13,[30][31][32][33][34][35][36][37][38][39][40][41][42], airborne particulate matter [15-19, 27, 33, 34, 42-53], industrial emissions [49], carbon black, and toners [3,[54][55][56] . All these matrices are extremely complex, since thousands of combustion products are generally present in the sample.…”

A procedure for the determination of nitro-substiruted polynuclear aromatic hydrocarbons (nitro-PAH) on crude air-particulate and soil extracts is introduced. Elimination of purification and fractionation procedures was made possible by the use of both a selective ionization method, such as electron-capture chemical ionization, and a specific fragmentation process, in an experiment of tandem mass spectrometry (gas chromatography-electron capture tandem mass spectrometry). Different mass spectrometric procedures were compared. The best performance was observed when the nitro-PAH molecular ions [M](-) were mass-selected by the first analyzer under multiple reaction monitoring conditions and then fragmented to NO 2 (-) (m/z 46). Detection limits were on the order of hundreds of femtograms, as determined in extracts of real environmental samples. This corresponds approximately to 5-15 pg of nitro-PAH per cubic meter of air sampled. Calibration curves were linear over 3 orders of magnitude. Applications to contamination from motor vehicle combustion and the iron industry are briefly discussed.
