Biomarker responses and PAH ratios in fish inhabiting an estuarine urban waterway
(2017-10-01)
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
(Victória, 2014-03-15)
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 ...
PAHs contamination in edible gastropods from north Patagonian harbor areas
(Pergamon-Elsevier Science Ltd, 2018-10)
PAHs are persistent pollutants released into the environment by fossil fuels burning and leak during petroleum operations. Associated with suspended particles upon entering marine ecosystem are accumulated by benthic fauna. ...
Detection of PAHs on calixarene-functionalized metal surfaces by means of SERS spectroscopy Detección de PAHs mediante espectroscopía SERS sobre superficies metálicas funcionalizadas con calixarenos
(2007)
Polycyclic Aromatic Hydrocarbons (PAHs) were detected at trace concentrations. In order to accomplish that, new SERS substrates were developed based on silver nanoparticles, both in suspension and immobilized in glass. ...
Polycyclic aromatic hydrocarbons from wood pyrolyis in charcoal production furnaces
(Elsevier B.V., 2006-07-01)
Polycyclic aromatic hydrocarbons (PAH) were measured in smoke samples from wood carbonization during charcoal production, in both particulate matter (PM) and gaseous phases. Samples were acquired using a medium-volume air ...
