Environmental Impacts, Health Risks, and Biodegradation Strategies of Fluorene and Other Polycyclic Aromatic Hydrocarbons

Journal of Pure and Applied Microbiology
Polycyclic aromatic hydrocarbons (PAHs) are organic compounds, composed of two or more fused benzene rings sourced from unburned fossil fuels and petroleum, recognized for their wide presence in the environment and harmful impacts on human health and ...

Site-selective covalent functionalization at interior carbon atoms and on the rim of circumtrindene, a C36H12 open geodesic polyarene

Beilstein Journal of Organic Chemistry, 2014
Circumtrindene (6, C36H12), one of the largest open geodesic polyarenes ever reported, exhibits fullerene-like reactivity at its interior carbon atoms, whereas its edge carbons react like those of planar polycyclic aromatic hydrocarbons (PAHs).

Cyclic Alkyne Approach to Heteroatom-Containing Polycyclic Aromatic Hydrocarbon Scaffolds [PDF]

, 2019
We report a modular synthetic strategy for accessing heteroatom-containing polycyclic aromatic hydrocarbons (PAHs) that relies on the controlled generation of transient heterocyclic alkynes and arynes.

First direct detection of large polycyclic aromatic hydrocarbons on asteroid (162173) Ryugu samples: An interstellar heritage

Natural Sciences
Polycyclic aromatic hydrocarbons (PAHs) are considered major players in the physics and chemistry of star‐ and planet‐forming regions. The interstellar PAH hypothesis is based on our understanding of the origin of the aromatic infrared bands (AIBs), a ...

Optimization Strategy of Polycyclic Aromatic Hydrocarbon Contaminated Media Bioremediation through Biosurfactant Addition

Chemical Engineering Transactions, 2014
A microbial surfactant was investigated for its potential to enhance bioavailability and, hence, the biodegradation of PAHs contaminated soil. Phenanthrene, a 3-ring polycyclic aromatic hydrocarbon (PAH), was chosen as a model target compound.

A Comparison of Polycyclic Aromatic Hydrocarbon Mobilization from Environmental Matrices [PDF]

A method has been developed to analyse PAHs in solid environmental matrices using an in-situ PFE-GC-MS method. The method involves the use of 2 g of alumina as the in-situ clean-up sorbent, in order to remove interferences and impurities in the soils ...
