Advances in PAHs/nitro-PAHs fractioning [PDF]
Analytical Methods, 2010 The aim of this work was to develop an efficient methodology for the reliable fractioning of nitrated-polycyclic aromatic hydrocarbons (nitro-PAHs) and polycyclic aromatic hydrocarbons (PAHs). Unlike what usually occurs under pressures developed by HPLC (high performance liquid chromatography) systems (above 11 bar) we observed that when normal phase ...

Laboratory Photo-chemistry of PAHs: Ionization versus Fragmentation [PDF]
, 2015 Interstellar polycyclic aromatic hydrocarbons (PAHs) are expected to be strongly processed by vacuum ultraviolet photons. Here, we report experimental studies on the ionization and fragmentation of coronene (C24H12), ovalene (C32H14) and hexa-peri ...

Biodegradation of Mixed PAHs by PAH-Degrading Endophytic Bacteria [PDF]
International Journal of Environmental Research and Public Health, 2016 Endophytic bacteria can promote plant growth, induce plant defence mechanisms, and increase plant resistance to organic contaminants. The aims of the present study were to isolate highly PAH-degrading endophytic bacteria from plants growing at PAH-contaminated sites and to evaluate the capabilities of these bacteria to degrade polycyclic aromatic ...
