Effects of the Desorption and Dissolution of Polycyclic Aromatic Hydrocarbons on Phytoremediation at a Creosote-Contaminated Site
… hydrophobic polycyclic aromatic hydrocarbons (PAH's), is present in the subsurface environment at the Oneida Tie-Yard in Oneida, Tennessee. Phytoremediation using hybrid poplar trees was chosen as the remedial technology on-site. Since monitoring began, the contaminant plume has been shrinking …

Direct measurement and analysis of cyclohexadienyl oxidation
… soot and other large polyaromatic hydrocarbons (PAH's). Thus, the cyclohexadienyl radical moiety is important in many chemical processes, and its detailed study is of interest in many areas. In this work, cyclohexadienyl radical is studied both computationally and experimentally in the liquid and …

Multiscale simulation of methane assisted fluidized bed biomass gasification
… generation of polycyclic aromatic hydrocarbons (PAH's), which require expensive cleanup steps to avoid downstream operational issues. Existing approaches to optimize the performance of FBBG have examined the manipulation of operational parameters such as temperature, pressure, in-bed additives, …

Hepatic CYP1A enzymes in fish as a biomarker of water pollution
… been used as a biomarker to detect exposure to PAH and to a certain extent PCB-like compounds. In the present study, Chinook salmon (Oncorynchus tschawytscha) were used as an animal model (i) to examine the induction of liver cytochrome CYP1A enzymes by β-napthoflavone (BNF) and Araclor 1254 …

Impact of modified carbon dioxide mobile phases on detection on packed-column supercritical fluid chromatography
… headspace CO₂. SFC of polyaromatic hydrocarbons (PAH) was performed with pure carbon dioxide and helium headspace carbon dioxide at various cylinder fill levels. The capacity factors of the PAH's increased when helium headspace carbon dioxide was used as a carrier fluid relative to pure carbon …

Extending the Limits of Solid Phase Microextraction
… standards of polycyclic aromatic hydrocarbons (PAH) at part per billion levels and to detect and quantify PAHs in fish oil. Samples from menhaden fish were collected in 2010 to study the effect of Gulf of Mexico oil spill on marine life. The method presented a linear range from 50-1500 ng/g, …

Raman spectroscopic application for the analysis of organic compounds and minerals of astrobiological significance. The detection and discrimination of organic compounds and mineral analogues in pure and mixed samples of astrobiological significance using raman spectroscopy, XRD and scanning electron microscopy
… excitation -polycyclic aromatic hydrocarbons (PAHs), organic acids, chlorophyll and carotenoids. Experimental mixtures of ß-carotene in usnic acid, PAHs in usnic acid and PAHs in mineral matrices have also been investigated. Organic compounds and PAHs located under crystalline minerals samples …
