“…In a previous study [19], seasonal behavior was reported for all nine PAHs, presenting maximums in winter (ca. 300 pg•m −3 ) and minimums in summer (ca.10 pg•m −3 ) for aerosol PAHs monitored at the Noto Peninsula between 2007 to 2014.…”

“…300 pg•m −3 ) and minimums in summer (ca.10 pg•m −3 ) for aerosol PAHs monitored at the Noto Peninsula between 2007 to 2014. It was reported that these aerosol PAHs had pyrogenic origins [19], and the seasonality was attributed to long-range transport from Northeast China to Japan in the cold seasons and domestic sources in the warm season [19].…”

“…At the Noto Air Monitoring Station of Kanazawa University in the Noto Peninsula, levels of aerosol PAHs have been monitored to investigate the influences of cross-border pollutants [19], exhibiting a seasonal variation in the levels of aerosol PAHs, which are higher in winter than in summer; however, the behavior of PAHs in aquatic environments is not-well known for this or other Japanese local areas. As mentioned above, the distribution of PAHs in the sea environment must also be investigated for the preservation of ecosystems and fisheries around the local regions.…”

To improve the understanding of the emission sources and pathways of polycyclic aromatic hydrocarbons (PAHs) in the coastal environments of remote areas, their particulate and dissolved concentrations were analyzed on a monthly basis from 2015 to 2018 in surface waters of Nanao Bay, Japan. The concentration of the targeted 13 species of PAHs on the United States Environmental Protection Agency (USEPA) priority pollutant list in dissolved and particle phases were separately analyzed by high-performance liquid chromatography (HPLC) coupled to a fluorescence detector. Particulate and dissolved PAHs had average concentrations of 0.72 ng∙L−1 and 0.95 ng∙L−1, respectively. While most of the samples were lower than 1 ng∙L−1, abnormally high levels up to 10 ng∙L−1 were observed in the winter of 2017–2018 for particulate PAHs. Based on the isomer ratios of Flu to Flu plus Pyr, it was possible to determine that the pyrogenic loads were greater than the petrogenic loads in all but four out of 86 samples. The predominant environmental pathway for PAHs in winter was determined to be long-range atmospheric transportation fed by the East Asian winter monsoon, while for the summer, local sources were more relevant. By the risk quotients method, it was determined that PAHs in surface seawater presented a very low risk to marine life during the interannual survey.

“…For the analysis of PAHs in airborne particulates, GC-MS using electron ionization (70 eV) mode and HPLC-fluorescence detection (HPLC-FL) are the most common methods (Araki et al, 2009;Chen et al, 2011;Liu et al, 2007;Zhang et al, 2010). Applications of these methods to all or some subset of the US Environmental Protection Agency (US-EPA) 16 priority PAHs (Ma et al, 2013;Tang et al, 2015;Xu, Lv, Cheng, & Li, 2015;Zhang et al, 2016) and World Health Organization (WHO) 17 PAHs (Feng et al, 2012;Hong et al, 2016;Omar et al, 2002) were determined because of their carcinogenicity and/or mutagenicity. Recently, GC-MS and HPLC-FL methods were reported for determining benzo[c]fluorene, whose relative potency factor with respect to the mutagenicity of benzo [a]pyrene are about 20, as reported by US-EPA (Morisaki et al, 2016;Yagishita et al, 2015).…”

Polycyclic aromatic hydrocarbons (PAHs) and nitropolycyclic aromatic hydrocarbons (NPAHs) are ubiquitous environmental pollutants. Moreover, some oxidative metabolites of these pollutants, such as hydroxylated and epoxide PAHs, cause endocrine disruption or produce reactive oxygen species. These compounds have become a large concern from the viewpoint of particulate matter (PM ) pollution. This report deals with recent studies concerning analytical methods for PAHs, NPAHs and related compounds in atmospheric and biological samples.

“…43,44) In our 10-year observation (from September 2004 to September 2014) showed that the atmospheric concentrations of PAHs as well as NPAHs at NAMS repeated the same seasonal variation (high in winter and low in summer). It is important that the atmospheric PAHs level at NAMS decreased in recent year, although no statistically significant change was found in warm season 45) (Fig. 12).…”
