Autor: Lothar Dunemann, Hossein Hajimiragha, Jutta Begerow, Robin Sur
Publikováno v: Chemie in unserer Zeit. 37:248-256
Eine neuartige Kopplungstechnik fur die Bestimmung von Hintergrundkonzentrationen an Trimethylarsinoxid (TMAO) und anderen Metaboliten des Arsens im menschlichen Urin wurde entwickelt. Die Ergebnisse liefern neue Einblicke in den Arsen-Metabolismus i

Autor: Jürgen Wittsiepe, Jutta Begerow, Michael Wilhelm, Lothar Dunemann, Petra Schrey
Publikováno v: Journal of Trace Elements in Medicine and Biology. 17:117-122
The dietary intake of platinum and gold by 84 small children, 42 boys and 42 girls at the age of 14 to 83 months, with different food consumption behaviour living in urban and rural areas of Germany was measured by the duplicate method with a seven d

New horizons in human biomonitoring of environmentally and occupationally relevant metals—sector-field ICP-MS versus electrothermal AAS
Autor: Lothar Dunemann, Martina Turfeld, Jutta Begerow
Publikováno v: J. Anal. At. Spectrom.. 15:347-352
Sector-field ICP-MS (SF-ICP-MS) was used for the quasi-simultaneous determination of selected trace and ultra-trace elements of occupational and environmental interest, such as Al, Co, Cr, Cu, Fe, Mn, Ni, Pt, V and Zn, in human urine and serum. In th

Internal platinum, palladium, and gold exposure in environmentally and occupationally exposed persons
Autor: Ulrich Sensen, Jutta Begerow, Gerhard Andreas Wiesmüller, Lothar Dunemann
Publikováno v: Zentralblatt für Hygiene und Umweltmedizin. 202:411-424
In a pilot study the urinary platinum (Pt), palladium (Pd), and gold (Au) excretion was analyzed in 27 dental technicians, 17 road construction workers and 17 school-leavers using sector field inductively coupled plasma mass spectrometry (SF-ICP-MS).

Determination of arsenic species in human urine using HPLC with on-line photooxidation or microwave-assisted oxidation combined with flow-injection HG-AAS
Autor: R. Sur, Jutta Begerow, Lothar Dunemann
Publikováno v: Fresenius' Journal of Analytical Chemistry. 363:526-530
An improved analytical procedure is presented for the separation and simultaneous determination of hydride-forming (toxic) and not hydride-forming (non-toxic) arsenic species in human urine. Separation was performed by cation-exchange chromatography

Performance of two different types of passive samplers for the GC/ECD-FID determination of environmental VOC levels in air
Autor: E. Jermann, Türkan Keles, Jutta Begerow, Lothar Dunemann
Publikováno v: Fresenius' Journal of Analytical Chemistry. 363:399-403
Two types of passive samplers differing in their geometry (OVM 3500 by 3M, ORSA 5 by Drager) were compared with respect to their suitability for typical environmental indoor and outdoor VOC concentrations. Benzene, toluene, o-, m-, p-xylene, ethylben

Determination of physiological noble metals in human urine using liquid-liquid extraction and Zeeman electrothermal atomic absorption spectrometry
Autor: Jutta Begerow, Martina Turfeid, Lothar Dunemann
Publikováno v: Analytica Chimica Acta. 340:277-283
An extremely sensitive, reliable and simple procedure is described for the determination of physiological palladium, platinum and gold in human urine. The urine samples were adjusted to pH 4 (Pd, Au) or pH 5 (Pt), followed by conversion of the analyt
