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. ...
Polycyclic aromatic hydrocarbons in milk powders marketed in Uruguay
(Taylor & Francis, 2017-07)
Polycyclic aromatic hydrocarbons (PAHs) occurrence in forty-four samples of milk powder, marketed in Uruguay, was determined. A high-performance liquid chromatography (HPLC) method was applied with fluorescence detector ...
Bioavailability of PAHs sequestered in sediment: microbial study and model prediction
(Environmental Toxicology and Chemistry, 2007)
Polycyclic Aromatic Hydrocarbons (PAHs) and nitrated analogs associated to particulate matter emission from a Euro V-SCR engine fuelled with diesel/biodiesel blends
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 ...
Quantifying the influence of meteorological variables on particle-bound PAHs in urban environments
Seasonal trend of polycyclic aromatic hydrocarbons (PAHs) associated with PM10 particles was assessed in an urban area in Cordoba, Argentina, during 2011-2013. In addition, we quantified the contribution of temperature, ...
Biomarker responses and PAH ratios in fish inhabiting an estuarine urban waterway
Many cities worldwide are established adjacent to estuaries and their catchments resulting in estuarine contamination due to intense anthropogenic activities. The aim of this study was to evaluate if fish living in an ...
QSAR model of the phototoxicity of polycyclic aromatic hydrocarbons
(Elsevier Science BvAmsterdamHolanda, 2005)
Sedimentary record of PAHs in the Barigui River and its relation to the socioeconomic development of Curitiba, Brazil
Concentrations of polycyclic aromatic hydrocarbons (PAHs) were determined in a sediment core collected from the Barigui River, in Curitiba, South Brazil. The USEPA's 16 priority PAH concentrations ranged from39 ng g−1 to ...
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 ...
