Cím:	Detection of nicotine as an indicator of tobacco smoke by direct analysis in real time (DART) tandem mass spectrometry / Ákos Kuki, Lajos Nagy, Tibor Nagy, Miklós Zsuga, Sándor Kéki
Dátum:	2015

Megjegyzések:	The residual tobacco smoke contamination (thirdhand smoke, THS) on the clothes of a smoker wasexamined by direct analysis in real time (DART) mass spectrometry. DART-MS enabled sensitive andselective analysis of nicotine as the indicator of tobacco smoke pollution. Tandem mass spectrometric(MS/MS) experiments were also performed to confirm the identification of nicotine. Transferred thirdhandsmoke originated from the fingers of a smoker onto other objects was also detected by DART massspectrometry. DART-MS/MS was utilized for monitoring the secondhand tobacco smoke (SHS) in the airof the laboratory using nicotine as an indicator. To the best of our knowledge, this is the first report onthe application of DART-MS and DART-MS/MS to the detection of thirdhand smoke and to the monitoringof secondhand smoke

Cím:	Properties and sources of individual particles and some chemical species in the aerosol of a metropolitan underground railway station / Imre Salma, Mihály Pósfai, Kristóf Kovács, Ernő Kuzmann, Zoltán Homonnay, József Posta
Dátum:	2009
ISSN:	1352-2310
Megjegyzések:	Aerosol samples in PM10-2.0 and PM2.0 size fractions were collected on the platform of a metropolitan underground railway station in central Budapest. Individual aerosol particles were studied using atomic force microscopy, scanning electron microscopy and transmission electron microscopy with energy-dispersive X-ray spectrometry and electron diffraction. The bulk aerosol samples were investigated by Fe-57 Mossbauer spectroscopy, and they were subjected to chemical speciation analysis for Cr. The particles were classified into groups of iron oxides and iron, carbonates, silicates, quartz and carbonaceous debris. Electron micrographs showed that the Fe-rich particles in the PM2.0 size fraction typically consisted of aggregates of nano-sized hematite crystals that were randomly oriented, had round shapes and diameters of 5-15 nm. In addition to hematite, a minor fraction of the iron oxide particles also contained magnetite. In addition, the PM2.0-fraction particles typically had a rugged surface with layered or granular morphologies. Mossbauer spectroscopy suggested that hematite was a major Fe-bearing species in the PM10-2.0 size fraction; its mass contribution to the Fe was 36%. Further constituents (ferrite, carbides and FeOOH) were also identified. The water soluble amounts of Cr for the underground railway station and city center were similar. in the PM10-2.0 size fraction, practically all dissolved Cr had an oxidation state of three, which corresponds to ambient conditions. In the PM2.0 size fraction, however, approximately 7% of the dissolved Cr was present as Cr(VI), which was different from that for the urban aerosol. It is suggested that the increased adverse health effects of aerosol particles in metros with respect to ambient outdoor particles is linked to the differences in the oxidation states, surface properties or morphologies.
