Unlabelled: Polycyclic aromatic hydrocarbons (PAHs) were analyzed using gas chromatography-mass spectrometry in 115 dairy products and beverages, including alcoholic, grain, carbonated, and functional drinks; fruit and vegetable juices; coffee; and tea, purchased from 10 local city markets in South Korea. The sample groups were divided into non-fatty and fatty groups, pretreated with the ultrasound-assisted extraction method and saponification method, respectively. The limit of detection, limit of quantification, and accuracy were 0.038-0.185 μg/kg, 0.114-0.560 μg/kg, and 87.64-112.25%, respectively. The measurement uncertainty was ≤ 6.38% for eight PAHs (PAH8). PAH8 was detected in 41 of the 115 samples, ranging from 0.041 to 7.793 µg/kg. The risk assessment revealed that the margin of exposure for PAH8 ranged from 3.60 × 10 to 7.84 × 10 in the mean intake groups and from 3.60 × 10 to 5.33 × 10 in the P97.5 intake groups.

Polycyclic aromatic hydrocarbons (PAHs) exhibit intriguing characteristics that position them as promising candidates for advancements in organic semiconductor technologies. Notably, tetracene finds substantial utility in Electronics due to its application in organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). The strategic introduction of an isoelectronic boron-nitrogen (B,N) pair to replace a carbon-carbon pair in acenes introduces changes in the electronic structure, allowing for the controlled modulation of diradical characteristics.

We report the synthesis, structural characterization and magnetic properties of Kcoronene, and demonstrate a computational screening workflow designed to accelerate the discovery of metal intercalated polycyclic aromatic hydrocarbon (PAH), a class of materials of interest following reports of superconductivity, but lacking demonstrated and understood characterised material compositions. Coronene is identified as a suitable PAH candidate from a library of PAHs for potassium intercalation by computational screening of their electronic structure and of the void space in their crystal structures, targeting LUMO similarity to C and the availability of suitable sites to accommodate inserted cations. Convex hull calculations with energies from crystal structure prediction based on ion insertion into the identified void space of coronene suggest that the = 3 composition in K coronene is stable at 0 K, reinforcing the suitability of coronone for experimental investigation.

This study evaluated the concentrations of polycyclic aromatic hydrocarbons (PAHs) and the carcinogenic risks of cattle and goat meats singed with either firewood, Liquefied Petroleum Gas (LPG) or tyres from five cities in Ghana. The meat samples, before and after singeing, as well as after scraping and washing, were collected from abattoirs and sent to Clinical Analysis Laboratory (Can-Lab) of Kwame Nkrumah University of Science and Technology (KNUST) for PAH analysis. Tyre-singed meats exhibit significantly higher PAHs concentrations ( = .

Polycyclic aromatic hydrocarbons (PAHs) are pervasive organic pollutants in the environment that are formed as an outcome of partial combustion of organic matter. PAHs pose a significant threat to ecological systems and human health due to their cytotoxic and genotoxic effects. Therefore, an immediate need for effective PAH remediation methods is crucial.
