A CONTRIBUTION TO THE ECOLOGY AND ENOLOGY OF PLATINUM

Since the introduction of the catalytic cleaning of vehicle exhaust ga ses, platinum is discussed as environmentally relevant element. Result s of such investigations are compared with ''natural'' platinum backgr ound concentrations, which were determined in selected environmental a nd biological samples. Wine serves as an example for the following the path of platinum, beginning with the uptake during the plant growth, continuing with the fermentation process of grape juice and resulting in the final product.
