Mixture effects of oxygenated PAHs and benzo[a]pyrene on cardiovascular development and function in zebrafish embryos

Environment International, 2020
Polycyclic aromatic compounds (PACs), including polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (oxy-PAHs), are common environmental pollutants known to cause health effects in humans and wild-life.

Response of Root Exudates of Bruguiera gymnorrhiza (L.) to Exposure of Polycyclic Aromatic Hydrocarbons

Frontiers in Environmental Science, 2022
Root exudates play a pivotal role in the behaviors of polycyclic aromatic hydrocarbons (PAHs) in mangrove sediments, but the knowledge of how mangrove root exudates response to PAHs pollutants is limited.

Donor–Acceptor Pentacene Analogues With Near‐Infrared Emission and Tunable Aromaticity

Angewandte Chemie, EarlyView.
Air‐ and photostable heterocyclic pentacene analogues with donor and acceptor groups flanking a para‐quinodimethane core exhibit large dipole moments, narrow bandgaps, reversible redox behavior, and NIR‐I to NIR‐II absorption and emission with pronounced solvatochromism.

Assessment of soil contamination by oil-derived compounds in the Kielce agglomeration using gas chromatography coupled with mass spectrometry (GC-MS) [PDF]

E3S Web of Conferences, 2019
Soil contamination with petroleum-derived compounds is one of the most serious ecological problems. Their main source in urbanized areas is public transport.

Indoor levels of polycyclic aromatic hydrocarbons (PAHs) from environment tobacco smoke of public bars

Ecotoxicology and Environmental Safety, 2021
In this work level of Polycyclic Aromatic Hydrocarbon (PAHs) from indoor Environment Tobacco Smoke (ETS) of pubic bars in Nigeria was investigated. Indoor air samples were obtained from different public bars using Polyurethane foam (PUF) passive samplers.

Ring‐Opening Arylation of Cyclic Diaryliodoniums via Cyclic Triaryliodanes as Aryne Precursors and Dynamic Aryl Reservoirs

Angewandte Chemie, EarlyView.
Cyclic diaryliodonium salts engage aryl Grignard reagents to trigger a self‐propagating aryne–arylation cycle. Transient cyclic triaryliodanes serve as aryne precursors and dynamic aryl reservoirs, delivering iodine‐capped teraryls with predominant meta‐selectivity. The preserved C─I bond enables outward π‐extension or inward recyclization.
