摘要：

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 mug/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 mum. The lowest concentrations were observed for the larger particles (> 8 mum). 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.
