The effect of five different vinegars, applied as a seasoning, on the formation of polycyclic aromatic hydrocarbons (PAH) in charcoal-grilled pork loin was investigated. PAH were assayed using acetonitrile based-extraction and high-performance liquid chromatography with fluorescence detection. Unseasoned samples presented a mean value of 31.47 ng g of PAH4 (sum of benz[a]anthracene, chrysene, benzo[b]fluoranthene and benzo[a]pyrene), near the maximum established by European Union (30 ng g). Significant reduction (p < .05) of PAH4 formation was observed in meat samples sprayed with vinegar. Elderberry vinegar exhibited the highest inhibition (82%), followed by white wine vinegar (79%), red wine and cider vinegars (66%), and fruit vinegar with raspberry juice (55%). The total phenolic content and antioxidant activities of vinegars had a moderate negative correlation with PAH4 formation, and 3rd degree polynomial equations had the best fitting performance to explain this relation. Spraying meat with these vinegars prior grill is an easy-to-apply strategy to limit the exposure to PAH.

The mechanism underlying the effects of Polycyclic aromatic hydrocarbons (PAHs) on missed abortion (MA) remains unclear. This study explored the relationship between PAHs exposure, telomere length (TL), metabolizing enzyme gene polymorphism, and MA in a case-control study with 253 pregnant women. A competitive enzyme-linked immunosorbent assay (ELISA) was used to quantify PAH-DNA adducts.

The behavior of polycyclic aromatic hydrocarbons (PAHs) released from tire road wear particles (TRWPs) in human digestive fluids may pose a significant risk to human health. However, the current understanding of the release pattern and influencing factors of PAHs from TRWPs is still insufficient. In this study, the release characteristics of PAHs from UV-aging TRWPs (ATRWPs) were systematically investigated by in vitro digestive simulation experiments, release kinetic model fitting and control variable experiments.

Context: High-nitrogen polycyclic compounds have become a research hotspot in the design of new energetic molecules due to their dense nitrogen content, high positive enthalpy of formation, and good structural stability. In particular, the fused structures of triazole and triazine heterocycles can not only enhance energy output but also possess excellent thermal stability. This study focuses on three triazolotriazine energetic compounds: 3,7-dinitro-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4-amine (TTX), 7-nitro-3-(1H-tetrazol-5-yl)-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4-amine (compound 1), and 3,3'-dinitro-[7,7'-bi[1,2,4]triazolo[5,1-c][1,2,4]triazine]-4,4'-diamine (compound 2).

Propargyl radical (•C3H3) and butadienyl radical (•i-C4H5) are two crucial intermediates in combustion and astrochemistry, particularly in the formation of C7H8 aromatics such as toluene. However, the precise formation mechanisms of the first-ring aromatics through C3 + C4 reactions have remained ambiguous. This study explores the detailed potential energy surface (PES) of C7H8 at the •C3H3 + •i-C4H5 entrance reaction channel, alongside conducting kinetic calculations and modeling.

The coking industry is a major source of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs). Although some OPAHs are considered to be more toxic than PAHs, limited information is available on the levels of PAH and OPAH emissions from the coking industry. Accordingly, we measured the emission factors (EF) for PAHs and OPAHs produced by the coking industry in China.
