| Abstract: | Summary During a period of almost one year airborne dust was collected at the area of ISAS, Dortmund. The total platinum content varied from 0.6 to 130 µg/kg, respectively from 0.02 to 5.1 pg/m3. The impactor measurements resulted in an equal distribution of platinum in combination with particle sizes ranging between 0.5 and 8 µm. The lowest concentrations were observed for the larger particles (>8 m). The  soluble platinum in airborne dust was determined to be 30 to 43% of the total amount of platinum and 2.5 to 6.9% in tunnel dust.Dedicated to Professor Dr. Wilhelm Fresenius on the occasion of his 80th birthday |
