“…The current postulated NO 3 radical-initialed reaction mechanism of PAHs is that NO 3 radicals attack the aromatic rings at the position of highest electron density in the PAH molecule (Arey et al, 1986;Atkinson et al, 1990;Gross and Bertram, 2008;Sasaki et al, 1997). According to the mechanism, the possible pathway of An-O 3 -NO is suggested as follows: first, NO 3 radicals can be expected to attack at position 9(10) of anthracene to form a NO 3 -An adduct; and then the adduct undergoes the reaction with NO 2 at position 10 (para-position) of anthracene; finally, 9-nitroanthracene is formed via H-atom abstraction and HNO 3 elimination.…”

The reactions of gas-phase anthracene and suspended anthracene particles with O 3 and O 3 -NO were conducted in a 200-L reaction chamber, respectively. The secondary organic aerosol (SOA) formations from gas-phase reactions of anthracene with O 3 and O 3 -NO were observed. Meanwhile, the size distributions and mass concentrations of SOA were monitored with a scanning mobility particle sizer (SMPS) during the formation processes. The rapid exponential growths of SOA reveal that the atmospheric lifetimes of gas-phase anthracene towards O 3 and O 3 -NO are less than 20.5 and 4.34 hr, respectively. The particulate oxidation products from homogeneous and heterogeneous reactions were analyzed with a vacuum ultraviolet photoionization aerosol time-of-flight mass spectrometer (VUV-ATOFMS). Gas chromatograph/mass spectrometer (GC/MS) analyses of oxidation products of anthracene were carried out for assigning the time-of-flight (TOF) mass spectra of products from homogeneous and heterogeneous reactions. Anthrone, anthraquinone, 9,10-dihydroxyanthracene, and 1,9,10-trihydroxyanthracene were the ozonation products of anthracene, while anthrone, anthraquinone, 9-nitroanthracene, and 1,8-dihydroxyanthraquinone were the main products of anthracene with O 3 -NO.

“…The chemical and physical behaviors of PAHs are much more complicated than those of fluoride. Atmospheric reactions of PAHs, such as radical reactions and photolysis degradation, result in the half lives of PAHs that from a few days to a few weeks (Arey et al, 1986;Hayakawa et al, 2002). Unlike PAHs, fluoride doesn't have a half-life in the atmosphere.…”

“…Some NPAHs, e.g. 3-nitrofluoranthene (3-NFLT) and 1-nitropyrene (1-NPYR), are associated specifically with combustion sources, whereas others such as 2-nitrofluoranthene (2-NFLT) and 2-nitropyrene (2-NPYR) are 10 produced through gas phase reaction of FLT and PYR with OH radicals and NOx (Arey et al, 1986;Bandowe and Meusel, 2017). NPAHs are also formed through reactions in the aerosol condensed phase (Keyte et al, 2013;Jariyasopit et al, 2014).…”

Nitrated and oxygenated polycyclic aromatic hydrocarbons (N/OPAHs) are emitted in combustion processes and formed in polluted air. Their precipitation cycling has hardly been studied. Fresh snow samples at urban and rural sites in central Europe, as well as surface snow from a remote site in Svalbard were analysed for 17 NPAHs, 9 OPAHs, and 11 nitrated mono-aromatic hydrocarbons (NMAHs), of which most N/OPAHs as well as nitrocatechols, 5 nitrosalicylic acids, and 4-nitroguaiacol are studied for the first time in precipitation. In order to better understand the scavenging mechanisms, the particulate mass fractions (Ө) at 273K were predicted using a multiphase gas-particle partitioning model based on polyparameter linear free energy relationships. ∑NPAH concentrations were 1.2-17.6 and 8.8-19.1 ng L -1 at urban and rural sites, whereas ∑OPAHs were 0.3-1.1 and 0.5-2.4 µg L -1 at these sites, respectively.Acenaphthoquinone and 9,10-anthraquinone were predominant in snow dissolved and particulate phase, respectively. 10 NPAHs were only found in the particulate phase with 9-nitroanthracene being predominant followed by 2-nitrofluoranthene. Among NMAHs, 4-nitrophenol showed the highest abundance in both phases. The levels found for nitrophenols were in the same range or lower than those reported in the 1980s and 1990s. The lowest levels of ∑OPAHs and ∑NMAHs were found at the remote site (9.2 and 390.5 ng L -1 , respectively). N/OPAHs preferentially partitioned in snow particulate phase in accordance with predicted Ө, whereas NMAHs were predominant in the 15 dissolved phase, regardless of Ө. It is concluded that the phase distribution of non-polar N/OPAHs in snow is determined by their gas-particle partitioning prior to snow scavenging, whereas that for polar particulate phase substances, i.e. NMAHs, is determined by an interplay between gas-particle partitioning in the aerosol, particle mass size distribution, and dissolution during in-or below-cloud scavenging.Atmos.
