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

Journal 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.

Strain-induced skeletal rearrangement of a polycyclic aromatic hydrocarbon on a copper surface

Nature Communications, 2017
Mechanical strains can induce chemical transformations otherwise inaccessible by conventional stimuli. Here, the authors show the unusual strain-induced transformation of a polycyclic aromatic hydrocarbon on a metal surface by means of atomic force ...

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

Journal 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.

Three distinct conductance states in polycyclic aromatic hydrocarbon derivatives [PDF]

Royal Society Open Science
Tight-binding model (TBM) and density functional theory (DFT) calculations were employed. Both simulations have demonstrated that the electrical conductance for eight polycyclic aromatic hydrocarbons (PAHs) can be modulated by varying the number of ...

Discovery of the Pure Polycyclic Aromatic Hydrocarbon Indene (c-C9H8) with GOTHAM Observations of TMC-1 [PDF]

Astrophysical Journal Letters, 2021
Polycyclic aromatic hydrocarbons (PAHs) have long been invoked in the study of interstellar and protostellar sources, but the unambiguous identification of any individual PAH has proven elusive until very recently.

Detection of two interstellar polycyclic aromatic hydrocarbons via spectral matched filtering [PDF]

Science, 2021
Identifying PAHs in space Midinfrared spectroscopy has shown that polycyclic aromatic hydrocarbons (PAHs) are abundant in many astronomical objects, but this technique cannot determine which specific PAH molecules are present.

Early-life exposure to polycyclic aromatic hydrocarbons and ADHD behavior problems. [PDF]

PLoS ONE, 2014
Polycyclic aromatic hydrocarbons are widespread urban air pollutants from combustion of fossil fuel and other organic material shown previously to be neurotoxic.In a prospective cohort study, we evaluated the relationship between Attention Deficit ...

Comparative Assessment of Total Hydrocarbon Content and Bioaccumulation of Heavy Metals in Sarotherodon Melanotheron at Atlas Cove Area and Okobaba of Lagos Lagoon [PDF]

Iranica Journal of Energy and Environment, 2017
Industrial waste discharge has increased the hazard of water pollution. The total hydrocarbon content and bioaccumulation of heavy metals in Sarotherodon melanotheron at Atlas cove area and at Okobaba end of Lagoon Lagos were assessed between November ...

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

Вестник 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]

PeerJ, 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.
