Development of a detailed chemical mechanism (MCMv3.1) for the atmospheric oxidation of aromatic hydrocarbons
The Master Chemical Mechanism has been updated from MCMv3 to MCMv3.1 in order to take into account recent improvements in the understanding of aromatic photo-oxidation. Newly available kinetic and product data from the literature have been incorporated into the mechanism. In particular, the degradation mechanisms for hydroxyarenes have been revised following the observation of high yields of ri...
متن کاملHigh Temperature Oxidation of Aromatic Hydrocarbons
Even though several models for toluene oxidation have been developed [3-7], the high temperature combustion of this aromatic is not fully understood. Most high temperature studies of toluene carried out to date have involved monitoring the concentration profiles of reactants, stable intermediates, and final products in flow reactors using GC analyses. However, the ignition process of hydrocarbo...
متن کاملAtmospheric polycyclic aromatic hydrocarbons in Mumbai, India
Atmospheric particulate PAH concentrations were measured at two locations in Mumbai (formerly Bombay), India. Total PAH concentrations (seven compounds) at Saki Naka and Indian Institute of Technology (IIT) were 38.8 and 24.5 ng m~3. Pyrene and benz(a)anthracene#chrysene were abundant at both sites while benzo(b)#uoranthene and benzo(k)#uoranthene were abundant, in addition, at the IIT site. Th...
متن کاملOxidation of Polycyclic Aromatic Hydrocarbons under Sulfate-Reducing Conditions.
[(sup14)C]naphthalene and phenanthrene were oxidized to (sup14)CO(inf2) without a detectable lag under strict anaerobic conditions in sediments from San Diego Bay, San Diego, Calif., that were heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) but not in less contaminated sediments. Sulfate reduction was necessary for PAH oxidation. These results suggest that the self-purificatio...
متن کاملPolycyclic Aromatic Hydrocarbons in Atmospheric Depositions around the Venice Lagoon
Studies have revealed the potential risks to which human health and ecosystems are exposed in the Venice Lagoon, due to the atmospheric deposition of persistent pollutants such as trace metals and organic compounds. A total of seventy-seven atmospheric bulk deposition samples were collected monthly from April 2002 to December 2004, from three sites located in the cities of Mestre and Venice, an...
