The present study objective was to assess polycyclic aromatic hydrocarbons in Bizerte and Ghar El Melh Lagoons and to assess the potential risk to human health from its consumption. To reach these objectives twenty fish samples from each site were collected and 15 priority polycyclic aromatic hydrocarbons (PAHs) were analyzed in their muscles using high-performance liquid chromatography with a fluorescence detector. Total PAH sole concentrations from Bizerte and Ghar El Melh Lagoons were similar or lower to those recorded in other species from other regions across the world. In the studied fish species, the 2 and 3 ring PAHs are the dominated compounds that enter to the composition of PAHs which indicates that PAHs could be principally derived from a petrogenic origin for the both studied lagoons. The human health risk by sole consumption was evaluated and revealed to exhibit no hazard to the local population health concerning PAH intakes. The findings of this biomonitoring study will help in the implementation of sustainable environmental policies for effective water pollution control and the two investigated lagoons management.

2-Cyanoindene is one of the few specific aromatic or polycyclic aromatic hydrocarbon (PAH) molecules positively identified in Taurus molecular cloud-1 (TMC-1), a cold, dense molecular cloud that is considered the nearest star-forming region to Earth. We report cryogenic mid-infrared (550-3200 cm) and visible (16,500-20,000 cm, over the ← electronic transition) spectra of 2-cyanoindene radical cations (2CNI), measured using messenger tagging (He and Ne) photodissociation spectroscopy. The infrared spectra reveal the prominence of anharmonic couplings, particularly over the fingerprint region.

Charge transfer (CT) states in polycyclic aromatic hydrocarbons play crucial roles in determining their electronic properties and their potential applications in organic electronics. In this work, we investigate the nature of the excited states in monomers and π-stacked dimers of azulene-fused naphthalene and anthracene systems, focusing on the interplay between structure and excited-state properties. Four different isomers for azulene-fused naphthalene (, , , and ) and anthracene (, , , and ) are considered.

Abiotic and Biotic Dissipation in Natural Attenuation of Phenanthrene and Benzo[a]pyrene: A Systematic Quantification Study in Contrasting Soils.

Natural attenuation represents a significant ecosystem function for mitigating the quantity and toxicity of polycyclic aromatic hydrocarbons (PAHs) through both abiotic and biotic dissipation processes. This study systematically investigated abiotic and biotic dissipation of phenanthrene (Phe) and benzo[a]pyrene (BaP) in four soils over 360 days, using CSIA to quantitatively analyze δ³C changes and demonstrate biodegradation. The results indicated that extractable Phe was primarily attenuated via biodegradation (65% - 81%), as revealed by CSIA, with the δ³C changes ranging from 2.

Manipulating Crystal Packing and Self-Assembly by π-Extended and Isomeric Fused Strategies in Thiophene Ring-Terminated Polycyclic Aromatic Hydrocarbons.

Org Lett

Two series of polycyclic aromatic hydrocarbon isomers ( and , and and ) were designed and synthesized by isomerically fusing phenanthrene with thiophene and thieno[3,2-]thiophene, respectively. All of the new target molecules were confirmed by single-crystal X-ray analysis, and it was found that the solid-state packing can be effectively modulated through a combination of π-extended and isomeric fused strategies. Meanwhile, compared with thiophene ring-terminated isomers and , both having a V-shaped geometry and showing no obvious self-assembly behavior, π-extended unit thieno[3,2-]thiophene-terminated isomer displays a V-shaped structure with moderate self-assembly properties and isomer exhibits a C-shaped configuration with further enhanced self-assembly properties.

In the present research, an attempt has been made to develop a new thin film microextraction method for the extraction of several polycyclic aromatic hydrocarbons from aqueous samples collected from different industrial units prior to their analysis by gas chromatography combined with a flame ionization detector. In this approach, a thin iron mesh was modified by the formation of iron(II) oxinate on its surface and used for the extraction of analytes without an additional sorbent. For this purpose, first, the mesh was immersed in a sulfuric acid solution and then transferred into an 8-hydroxy quinoline (oxine) solution dissolved in ammonia solution.
