Anthropogenic Platinum Emission - Investigation of Peat Cores | ||
Temporal change of platinum concentration in the two peat cores. * 1971: construction and opening of the motor way in Guin (Düdingen) ** 1986: introduction of car exhaust catalysts in Switzerland |
||
The purpose of this study was to develop a robust, reliable and accurate method that allows platinum measurements in the sub-ppt level in complex matrices. This method, successfully applied to the determination of platinum in a wide variety of environmental, food and biological samples, permitted to assess the anthropogenic platinum emission in peat bogs from two locations, one near a well-frequented motorway, one from an alpine site as reference location.
This work was carried out by Céline Fragnière and Max Haldimann in the group of Prof. Urs Krähenbühl.
