Aryl radical addition–dehydrocyclization drives rapid polycyclic aromatic hydrocarbon growth [PDF]

open access: yesNature Communications
Polycyclic aromatic hydrocarbons are ubiquitous in space, yet astrochemical models fail to reproduce their observed abundances because known growth mechanisms are far too slow. Here, we report a plausible pathway for rapid polycyclic aromatic hydrocarbon

Association between urinary polycyclic aromatic hydrocarbon metabolites and sleep disturbances: A cross-sectional study integrating machine learning and network toxicology [PDF]

open access: yesJournal of International Medical Research
Objective Although humans are widely exposed to polycyclic aromatic hydrocarbons, current evidence on the association between urinary polycyclic aromatic hydrocarbon metabolites and sleeping troubles remains limited.

Effects of Different Interventions Aimed at Reducing Dermal and Internal Polycyclic Aromatic Hydrocarbon Exposure Among Firefighters [PDF]

open access: yesJournal of Xenobiotics
Firefighters are inherently exposed to soot and polycyclic aromatic hydrocarbons (PAHs) at work. In this repeated measures study, we assessed if three different interventions reduced PAH exposure.

Kinetic model and kerosene surrogate for calculating gas turbine engine emission of carcinogenic hydrocarbons

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2022
To calculate the emission of carcinogenic polycyclic aromatic hydrocarbons by the combustion chambers of aircraft gas turbine engines, the A17 kinetic model has been developed, characterized by new blocks of elementary chemical reactions of hydrocarbon ...

Vertical distribution of polycyclic aromatic hydrocarbons in the brackish sea water column: ex situ experiment [PDF]

open access: yesPeerJ, 2020
Background Oil spills can cause severe damage within a marine ecosystem. Following a spill, the soluble fraction of polycyclic aromatic hydrocarbons is rapidly released into the water column.

Determination of Polycyclic Aromatic Hydrocarbons in Traditional Chinese Medicine Raw Material, Extracts, and Health Food Products

open access: yesMolecules, 2022
The four polycyclic aromatic hydrocarbon markers (PAH4) of benzo[a]anthracene (BaA), chrysene (Chr), benzo[b]fluoranthene (BbF), and benzo[a]pyrene (BaP) are indicators showing polycyclic aromatic hydrocarbon (PAH) contamination levels in Chinese ...
