Journal ArticleDOI
Occurrence of the potent mutagens 2- nitrobenzanthrone and 3-nitrobenzanthrone in fine airborne particles
TL;DR: In the present study, 2-NBA, 3-NBA and selected PAHs and Nitro-PAHs were determined in fine particle samples collected in a bus station and an outdoor site, showing low cancer risk incidence and incremental lifetime cancer risk (ILCR) calculated for both places.
Journal ArticleDOI
Particulate pollutants in the Brazilian city of São Paulo: 1-year investigation for the chemical composition and source apportionment
Guilherme Martins Pereira,Guilherme Martins Pereira,Kimmo Teinilä,Danilo Custódio,Danilo Custódio,Aldenor Gomes Santos,Huang Xian,Risto Hillamo,Célia Alves,Jailson B. de Andrade,Gisele O. da Rocha,Prashant Kumar,Rajasekhar Balasubramanian,Maria de Fátima Andrade,Pérola de Castro Vasconcellos,Pérola de Castro Vasconcellos +15 more
TL;DR: In this article, a year-round sampling was performed at the University of Sao Paulo campus (20m) in Brazil to evaluate the sources of particulate air pollution and related health risks, and different chemical constituents, such as carbonaceous species, polycyclic aromatic hydrocarbons (PAHs), water-soluble ions, and biomass burning tracers were identified in order to evaluate health risks and to apportion sources.
Journal ArticleDOI
A simple, comprehensive, and miniaturized solvent extraction method for determination of particulate-phase polycyclic aromatic compounds in air.
Aldenor Gomes Santos,Ana Carla D. Regis,Gisele O. da Rocha,Marcos A. Bezerra,Marcos A. Bezerra,Robson M. de Jesus,Jailson B. de Andrade +6 more
TL;DR: This procedure was found to be precise, accurate and suitable to be employed for determination of polycyclic aromatic compounds in airborne particles from both polluted and non-polluted atmospheres.
Journal ArticleDOI
Assessment of the use of oxygenated fuels on emissions and performance of a diesel engine
Lílian Lefol Nani Guarieiro,Egídio Teixeira de Almeida Guerreiro,Keise Katiane dos Santos Amparo,Victor Bonfim Manera,Ana Carla D. Regis,Aldenor Gomes Santos,Vitor Pinheiro Ferreira,Danilo J. Leao,Edinildo A. Torres,Jailson B. de Andrade +9 more
TL;DR: In this article, the authors assess the use of oxygenated fuels on emissions of NOx, CO, HC, CO2 and particle number and size distribution (11.5 ).
Journal ArticleDOI
Methodology to examine polycyclic aromatic hydrocarbons (PAHs) nitrated PAHs and oxygenated PAHs in sediments of the Paraguaçu River (Bahia, Brazil).
TL;DR: A new analytical protocol for the determination of PACs in sediments using microextraction, which requires small sample masses, 500 μL of acetonitrile-dichloromethane mix and sonication for 23 min, followed by GC-MS analysis, showed good sensitivity, linearity, precision and accuracy.
