Toxicokinetics and bioconcentration of polycyclic aromatic hydrocarbons in freshwater isopods [PDF]
, 1999 A novel method based on a first-order two-compartment model was used to determine the bioconcentration and toxicokinetic rate constants of six different polycyclic aromatic hydrocarbons (PAHs) in the freshwater isopod Asellus aquaticus, a common species ...

Dehydrogenated polycyclic aromatic hydrocarbons and UV bump
, 2008 Recent calculations have shown that the UV bump at about 217.5 nm in the extinction curve can be explained by a complex mixture of PAHs in several charge states.

Low-temperature formation of polycyclic aromatic hydrocarbons in Titan’s atmosphere [PDF]
, 2018 The detection of benzene in Titan’s atmosphere led to the emergence of polycyclic aromatic hydrocarbons (PAHs) as potential nucleation agents triggering the growth of Titan’s orange-brownish haze layers. However, the fundamental mechanisms leading to the

Polycyclic aromatic hydrocarbons
, 2007 Polycyclic aromatic hydrocarbons (PAH) are a group of structurally related chemical compounds that are frequently produced during incomplete combustion of organic matter and are among the most widespread environmental pollutants. This chapter enumerates common sources of environmental PAH that contribute to human exposures including air and water ...

Strategies for producing biochars with minimum PAH contamination [PDF]
With the aim to develop initial recommendations for production of biochars with minimal contamination with polycyclic aromatic hydrocarbons (PAHs), we analysed a systematic set of 46 biochars produced under highly controlled pyrolysis conditions.
