Particulate matter analysis in indoor environments of urban and rural primary s...

Passive sampling methodology was applied to collect particulate matter (PM) in classrooms of urban and rural primary schools. The samples were taken during a year by passive deposition allowing the study of seasonal variability of the particles masses and chemical content.Chemical characterization of the collected particleswas performed in order to measure its soluble ions content and elemental composition. To ...

Biomarkers of exposure to metal dust in exhaled breath condensate: methodology ...

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 ...

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...

Aerosol optical properties at Santiago Island, Cape Verde.

European Aerosol Conference. Granada, Spain, 2-7 September 2012. ; > huge amounts of mineral dust are emitted every year from the Sahara desert to the atmosphere; > optical parameters of mineral aerosols determine the direct interaction of solar and terrestrial radiation in the atmosphere through scattering and absorption; > mineral dust has a great impact on cloud formation leading to additional indirect radi...
