摘要：

A joint study with the Federal Environment Agency of Austria was carried out to determine the distribution of Ru, Rh, Pd, Os, Ir and Pt (PGE) and Re in soils along major motorways. Emphasis was put on It as to date little is known about its anthropogenic input as this metal is now also used in automobile catalytic converters. Soil samples were analysed by lCP-MS through online-coupling of a chromatographic column to separate the PGEs from interfering matrix constituents. At all sampled sites not only Rh, Pd and Pt but also Ir and Re significantly exceed natural background values; concentrations reached 13 ng/g, 25 ng/g, 134 ng/g, 1.1 ng/g and 9.8 ng/g, respectively. The analytical procedure proved to be very selective and sensitive and, therefore applicable to routine soil analysis. (C) 2003 Elsevier B.V. All rights reserved.
