Biomarkers of exposure to metal dust in exhaled breath condensate: methodology ...
Félix, P. M.; Franco, C.; Barreiros, Maria Alexandra; Batista, B.; Bernardes, S.; Garcia, S. M.; Almeida, A. B.; Almeida, S. M.; Wolterbeek, H. Th.In occupational assessments where workers are exposed to metal dust, the liquid condensate of exhaled breath (EBC) may provide unique indication of pulmonary exposure. The main goal of this study was to demonstrate the quality of EBC to biological monitoring of human exposure. A pilot study was performed in a group of metal dust–exposed workers and a group of nonexposed individuals working in offices. Only meta...
Exhaled breath condensate as a biomonitor for metal exposure: a new analytical ...
Barreiros, Maria Alexandra; Pinheiro, Teresa; Félix, P. M.; Franco, C.; Santos, Mário J. G.; Araújo, F.; Freitas, Maria do Carmo; Almeida, S. M.The study of exhaled breath condensate (EBC) obtained by cooling exhaled air under conditions of spontaneous breathing is considered one of the areas with higher interest in respiratory health research. The use of EBC for elemental determination in occupational exposure requires a standard methodological procedure to implement its practice in occupational studies. EBC is an inhomogeneous sample with organic and...
Inter-annual variations of macrobenthic communities over three decades in a lan...
Correia, M.J.; Costa, J.L.; Chainho, P.; Félix, P.M.; Chaves, M.L.; Medeiros, J.P.; Silva, G.; Azeda, C.; P. Tavares, P.; Costa, A.; Costa, A.M.Santo André is an enclosed brackish water coastal lagoon with temporary connections to the sea by a man-made channel. The exchange and mixture of saltwater and freshwater is irregular and the lagoon may show daily and seasonal fluctuations, but also long-term variation. Different benthic communities may be present along the annual cycle according to the magnitude of episodic freshwater and sea water inputs. In ...
