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.

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.

Dispersion‐Clamped Crystalline Supramolecular Columnar π‐Stacks of Adamantyl‐Substituted Pyrenes

Angewandte Chemie, EarlyView.
Can neutral hydrocarbon π‐systems be forced into perfectly aligned cofacial stacks in crystals? An adamantyl‐decorated pyrene derivative crystallizes into rare translationally zero‐offset π‐columns, producing a short π–π distance below 3.3 Å and a large color shift arising from frontier crystal orbital (FCO) formation. ABSTRACT Despite their importance

Diversity‐Oriented Two‐Step Annulative π‐Extension Enables Access to Structurally Complex Nanographenes

Angewandte Chemie, EarlyView.
Pd‐catalyzed C–H arylation of polycyclic aromatic hydrocarbons (PAHs) with various aryltrimethylsilanes enables the preparation of structurally complicated arylated PAHs, which can be further transformed to nanographenes in a manner of two‐step annulative π‐extension (APEX) reaction.

ENVIROMENTAL HYDROCARBON CONTAMINATION IN RICOTTA AND MOZZARELLA DI BUFALA CHEESE

Italian Journal of Food Safety, 2010
Polycyclic aromatic hydrocarbons (PAHs), mainly formed by anthropogenic activities, are ubiquitous environmental contaminants. Due to environmental contamination and their chemical properties they migrate through the human food chain.

Introducing Diradicaloid Thiele's Hydrocarbon Derivatives as Ligand in Transition Metal Chemistry

Angewandte Chemie, EarlyView.
N‐doped Thiele's hydrocarbon derivative is introduced as a ligand for the synthesis of mono‐ and bimetallic rhodium complexes as well as cyclometalated iridium complexes. These compounds constitute the first metal complexes based on a Thiele's hydrocarbon (or p‐quinodimethane) derivative and, to the best of our knowledge, the first cyclometalated ...

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.
