Determination of Pt in urine of tram drivers by sector field inductively coupled plasma mass spectrometry

摘要

The Platinum Group Elements (PGEs) used in automotive catalytic converters are partly emitted into the air during use and can enter the human respiratory system. Due to the increasing use of automotive catalytic converters, the importance of this problem cannot be overlooked. The goal of this investigation was to determine the concentration of Pt in the urine of individuals occupationally exposed to urban air with heavy traffic. Sector field inductively coupled plasma mass spectrometry (SF-ICP-MS) was used for determination of Pt in the urine of train drivers. 38 and 34 subjects were investigated in Vienna and Budapest, respectively. Samples were taken from the train drivers both before and after the shift. The results for Pt were compared to those from a previous study performed by our team. The comparison showed that the concentration medians were 4 times higher than the previous ones. Moreover, the values in Budapest were about twice as high as those from Vienna. A partly significant change could be observed between the two sets of data: before, and after the shift. (C) 2007 Elsevier B.V. All rights reserved.
