Every year, Northern Thailand faces haze pollution during the haze episode. The particulate matter (PM), including fine fraction (PM 2.5), a coarse fraction (PM 2.5–10), and 16 polycyclic aromatic hydrocarbons (PAHs), was measured in six provinces in upper north Thailand during the haze and non-haze episodes in 2018.Eighty-three percent of …

PAHs Polycyclic Aromatic Hydrocarbons (PAHs) are naturally occurring substances composed of multiple carbon and hydrogen aromatic rings. They are found in fossil fuels and are often formed during incomplete combustion of organic materials.1 PAHs have a characteristic smell similar to that of car tires or asphalt. PAHs are typically

1. Introduction. Polycyclic aromatic hydrocarbons (PAHs) comprise over 200 organic compounds containing two or more fused aromatic rings [].According to the number of aromatic rings, they can be classified as light (2–3 rings) or heavy (4–6 rings) compounds [].Environmental PAHs can originate from natural sources, such as forest fires and …

378 PAHs and the Universe PAHs are very likely present in some form but as the simplest neutral systems are not polar no detection is possible through their rotational spectra. One mod-ification, and one subjected to a radioastronomical search, is corannulene which has a significant dipole moment as it is non-planar (Pilleri et al. 2009). PAHs
