PAH air pollution at a Portuguese urban area: carcinogenic risks and sources id...
Slezakova, Klara; Pires, J. C. M.; Castro, Dionísia; Alvim-Ferraz, Maria da Conceição M.; Delerue-Matos, Cristina; Morais, S.; Pereira, Maria do CarmoThis study aimed to characterize air pollution and the associated carcinogenic risks of polycyclic aromatic hydrocarbon (PAHs) at an urban site, to identify possible emission sources of PAHs using several statistical methodologies, and to analyze the influence of other air pollutants and meteorological variables on PAH concentrations.The air quality and meteorological data were collected in Oporto, the second l...

Contribution of traffic and tobacco smoke in the distribution of polycyclic aro...
Castro, Dionísia; Slezakova, Klara; Delerue-Matos, Cristina; Alvim-Ferraz, Maria da Conceição M.; Morais, S.; Pereira, Maria do CarmoTraffic emissions and tobacco smoke are considered two main sources of polycyclic aromatic hydrocarbons (PAHs) in indoor and outdoor air. In this study, the impact of these sources on the level of fine particulate matter (PM2.5) and on the distribution of 15 PAHs regarded as priority pollutants by the US-EPA on PM2.5 were evaluated and compared. Outdoor and indoor PM2.5 samples were collected during winter 2008...

Castro, Dionísia; Slezakova, Klara; Oliva-Teles, Maria Teresa; Delerue-Matos, Cristina; Alvim-Ferraz, Maria da Conceição M.; Morais, SimoneA methodology based on microwave-assisted extraction (MAE) and LC with fluorescence detection (FLD) was investigated for the efficient determination of 15 polycyclic aromatic hydrocarbons (PAHs) regarded as priority pollutants by the US Environmental Protection Agency and dibenzo(a,l)pyrene in atmospheric particulate samples. PAHs were successfully extracted from real outdoor particulate matter (PM) samples wit...
