Bacterial degradation of mixed-PAHs and expression of PAH-catabolic genes
World Journal of Microbiology and Biotechnology, 2022Polyaromatic hydrocarbons (PAHs) are hazardous organic compounds with established toxicity, carcinogenicity, and mutagenicity, ubiquitous distribution, and persistence in different environmental matrices. In the present study, degradation of the mixture of PAHs (phenanthrene, anthracene, fluorene, and pyrene) by Kocuria flava and Rhodococcus ...

PAH-pools in soils along a PAH-deposition gradient
Environmental Pollution, 1996The objectives of this study are to characterize different PAH-pools (soil horizons, microsites influenced by stem flow, aggregate core and surface fractions, particle size fractions) in soils affected by depositions. Three forest soils affected by the emissions of an aluminium plant near Ziar/Central Slovakia were sampled to analyze 20 PAHs.

Polycyclic aromatic hydrocarbons (PAHs) are known as one of the ubiquitous environmental pollutants caused by unavoidable combustion of by-products. Despite decades of research on adverse health effects towards humans, the effects of PAHs and their hydroxylated metabolites (OH-PAHs) on UDP-glucuronosyltransferases (UGTs) remain unclear.

Abstract Chapter 8, “The PAH: Building a Movement within a Movement,” analyzes the Platform for those Affected by Mortgages (PAH), a widely admired and highly valued organization within 15-M, and also the one that addresses one of the austerity issues with the highest social, economic, and personal impact: the housing crisis.

Modern PAH-Analysis and Fate of PAH in Air
1983Current analytical methods for the determination of PAH in environmental samples require the separation of individual compounds, either by thin layer or high performance liquid chromatography with fluorescence detection, or better, by gas chromatography on capillary columns, coupled to a flame ionisation detector or a mass spectrometer.

To improve our understanding of the formation and fate of nitro-PAHs, which contribute to the toxicity of ambient particles, the diurnal variation of their ambient concentration was studied concurrently with the corresponding PAH, OH radical, ozone, and oxy-PAH concentration, during an intensive field campaign at an eastern Mediterranean marine ...

Potential Energy Surfaces and Charge Transfer of PAH‐Sodium‐PAH Complexes
ChemPhysChem, 2016AbstractTo further understanding of the role of sodium in carbon cathode degradation in Hall–Héroult cells, potential‐energy surfaces and charge‐transfer curves are presented for finite‐size complexes of sodium intercalated between various polycyclic aromatic hydrocarbons.

Abstract Parent and alkyl PAHs (51 compounds and alkyl homologues) have been quantified in suspended particulates and sediments (345 samples) from the Fraser River system, British Columbia, Canada. The best potential to distinguish natural and anthropogenic sources is exhibited by ratios of the principal mass 178, 202, 228 and 276 parent PAHs, 1,7/2 ...
