Abstract:The introduction of automobile catalytic converters leads to the pollution of platinum group elements in environment. Microwave digestion-inductively coupled plasma mass spectrometry (ICP-MS) was applied for analysis of Pt in road fall dust of Shanghai city. The interference was eliminated effectively by mathematical correction. The average Pt content of the 20 sampling sites was 37.3ng/g with a range of 6.2~318.4ng/g. Enrichment factors calculation showed that Pt in road fall dust of Shanghai was derived from anthropogenic activities. A positive relation between the Pt contents and traffic flows was found. Compared with other cities in the world, the current pollution of Pt in Shanghai may be less serious. Pt in road fall dust were obviously higher than that in aerosol particles (PM10).
