Diurnal and nocturnal measurements of PAH, nitro-PAH, and oxy-PAH compounds in atmospheric particulate matter of a sugar cane burning region
(Elsevier B.V., 2014-02-01)
Polycyclic aromatic hydrocarbons (PAHs), nitro-PAHs, and oxy-PAHs were studied in the atmospheric particulate matter of a subtropical rural region (Sao Paulo State, Brazil) affected by emissions from sugar cane burning. ...
Avaliação de adsorventes sólidos para a remoção de derivados de HPAs em solução
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2014-03-12)
Polycyclic aromatic hydrocarbons, nitrogen and oxygen (Nitro-PAHs and Oxy-PAHs) compose the class of compounds where a hetero atom of nitrogen and oxygen, respectively, is present in the constitution of the HPA. The inclusion ...
Polycyclic Aromatic Hydrocarbons (PAHs) and nitrated analogs associated to particulate matter emission from a Euro V-SCR engine fuelled with diesel/biodiesel blends
(2018-12-10)
Among the new technologies developed for the heavy-duty fleet, the use of Selective Catalytic Reduction (SCR) aftertreatment system in standard Diesel engines associated with biodiesel/diesel mixtures is an alternative in ...
Similar polycyclic aromatic hydrocarbon and genotoxicity profiles of atmospheric particulate matter from cities on three different continents
(2020-06-01)
The extractable organic material (EOM) from atmospheric total suspended particles (TSP) contains several organic compounds including non-substituted polycyclic aromatic hydrocarbons (PAHs), alkyl-PAHs, and nitro-PAHs. These ...
Cinética de adsorção de derivados de hidrocarbonetos policíclicos aromáticos em EPU, PEAD, Amberlite XAD-2
(Universidade Federal de Santa MariaBrasilUFSMCentro de Ciências Naturais e Exatas, 2017-07-07)
Polycyclic Aromatic Hydrocarbons (PAH) are organic molecules stable constituted by aromatic rings fused. The PAH, nitrogenous and oxygenates (Nitro-PHA and Oxy-PHA) composes this class of compounds where there is the ...
Mutagenicity and DNA adduct formation of PAH, nitro-PAH, and oxy-PAH fractions of atmospheric particulate matter from Sao Paulo, Brazil
(ELSEVIER SCIENCE BV, 2008)
Urban particulate matter (UPM) contributes to lung cancer incidence. Here, we have studied the mutagenic activity and DNA adduct-forming ability of fractionated UPM extractable organic matter (EOM). UPM was collected with ...
Electrochemical reduction potentials of 1-nitropyrene, 9-nitroanthracene, 6-nitrochrysene and 3-nitrofluoranthene and their correlation with direct-acting mutagenicities
(2005)
Neste trabalho, são apresentados os potenciais de meia-onda de redução, determinados para 3-nitrofluoranteno (3-NF) = -0,51V, 1-nitropireno (1-NP) = -0,61V, 6-nitrocriseno (6-NC) = -0,64V, e 9-nitroantraceno (9-NA) = -0,84V. ...
