POLYCICLIC AROMATIC HYDROCARBON IN URBAN AEROSOL

Akari Observations of Interstellar Polyciclic Aromatic

Introduction: Polycyclic aromatic hydrocarbons (PAHs) are small organic matters found also in the interstellar space [1]. They are subjects of interest as distant ancestors of organic matters in our Solar system, in view of the life cycle of solid matters in space. Data and analysis: AKARI, Japanese infrared astronomical satellite, surveyed all the sky in the 9, 18, 65, 90 and 160 micron bands....

Polycyclic aromatic hydrocarbon selected galaxies

Context. This is the fourth in a series of papers based on the ISOCAM Parallel Survey at 6.7 μm. While the first three papers have been devoted to active galactic nuclei (AGN), here we report on emission-line galaxies without AGN signatures in their optical spectra. Aims. Polycyclic aromatic hydrocarbon (PAH) emission has been found in both starbursts and modestly starforming galaxies, but the ...

Characterization of elemental and polycyclic aromatic hydrocarbon compositions of the urban air in Brisbane

Characterization of the elemental and PAHs compositions of urban air was undertaken at three major sites in Brisbane, Australia. 17 elements and 16 US EPA priority PAHs were quantified at the sites. The most commonly detected elements in the TSP and PM2.5 fractions were Al, Cd, Co, Cr, Cu, Fe, Mn, Mo, Si, Sn, Sr and Zn. Compared to the two other sites, PM2.5 was found to contain higher concentr...

Polycyclic aromatic hydrocarbon exposure, obesity and childhood asthma in an urban cohort.

BACKGROUND Exposure to traffic-related air pollutants, including polycyclic aromatic hydrocarbons (PAHs) from traffic emissions and other combustion sources, and childhood obesity, have been implicated as risk factors for developing asthma. However, the interaction between these two on asthma among young urban children has not been studied previously. METHODS Exposure to early childhood PAHs ...
