“…The results obtained for 1-NPYR levels were similar to those reported in the literature for other cities of the world, like Marseilles [40], Paris [11], Ho Chi Minh [41], Copenhagen [15], Milan [42], Tokyo [43]; among others. It has been observed that 1-NPYR tends to predominate in diesel exhausts and this compound has also been identified in used oils from light-duty diesel engines.…”

For PM 2.5 and PM 10 collection different approaches were followed using different type of filters and sample collectors. Samples of PM 2.5 were collected on glass fiber filters during one month with a medium volume sampler. For PM 10 , glass and quartz fiber filters were used and samples were collected simultaneously for one week using a high volume sampler. In addition, bark samples were collected at the same sites.

“…[3][4][5] NPAHs, which generally exhibit higher mutagenicity and carcinogenicity than the parent PAHs, are also generated from atmospheric reactions of PAHs released into the gas-phase with radical species such as OH and NO 3 radicals and nitrogen oxides. [6][7][8][9][10] OPAHs and OHPAHs, which may show biological effects different from mutagenicity and carcinogenicity, are also known to be secondarily formed via oxidation of PAHs and NPAHs in the atmosphere. 11,12) These derivatized PAHs generally have lower volatility than the par- * To whom correspondence should be addressed: Institute of Medical, Pharmaceutical and Health Sciences, Kanazawa University, Kakuma-machi, Kanazawa, Ishikawa 920-1192, Japan.…”

Polycyclic aromatic compounds are ubiquitous atmospheric pollutants with toxic, mutagenic, and carcinogenic properties. They are produced from chemical reactions of their parent compounds in the atmosphere as well as from a wide variety of anthropogenic sources such as fuel combustions. The present review is mainly concerned with several reaction pathways regarding secondary formation of atmospheric polycyclic aromatic hydrocarbon (PAH) derivatives, i.e., formation of mutagenic nitrated PAHs, 1-and 2-nitrotriphenylene, via gas-phase OH or NO 3 radical-initiated reactions of the parent triphenylene, atmospheric formation of hydroxynitropyrenes from a photochemical reaction of 1-nitropyrene, and photochemical degradation of selected nitrated and oxygenated PAHs on airborne particles under simulated solar UV-irradiation.

“…Depuis peu on utilise l'extraction à l'aide de fluide supercritique [9], mais cette technique prometteuse n'a pas encore été calibrée avec les méthodes classiques. En général il n'est pas nécessaire d'effectuer une purification de l'échantillon, mais un fractionnement entre phase polaire et phase non polaire s'avère cependant souvent recommandable [10]. Certaines analyses demandent une pré-paration supplémentaire.…”

U n bilan complet de la composition particulaire nécessite de nombreuses techniques analytiques car aucune n'est universelle. Trois grands types de méthodes sont employés :• méthodes relatives aux composés inorganiques ou organiques solubles dans l'eau,• méthodes relatives aux espèces inorganiques peu ou non solubles telles que les métaux,• méthodes relatives aux composés organiques.La présentation des méthodes relatives aux composés inorganiques est effectuée par ailleurs. Nous détaillons ici les méthodes propres à l'analyse de la matière organique particulaire [1,2].Vue la diversité des composés chimiques constituant la matière organique particulaire (POM), les méthodes analytiques sont nombreuses et il n'existe aucune méthode répon-dant à tous les besoins. Dans tous les cas, la complexité de la matrice organique nécessite une séparation chromatographique préalable, et il n'est jamais possible, comme c'est parfois le cas avec la matière inorganique, d'effectuer directement une analyse sur le filtre lui-même. L'analyse de la matière organique reste donc longue et souvent délicate. La qualité des résultats est souvent inférieure à celle obtenue pour les métaux et les espèces inorganiques. Prélèvement de la matière organique particulaireSi l'on désire effectuer un bilan de la matière organique (spéciation complète), il est nécessaire d'utiliser des filtres et un système de pompage particuliers [3].To study the global composition of atmospheric particulate matter, several complementary sampling and analytical techniques or methods are required. In this paper, we focus on how to carry out the characterization and determination of the organic component of these particles (sampling, sample treatment, analytical techniques, …).
