| Abstract: | In order to study temporal variation characteristics and influencing mechanism of platinum group elements(PGEs) in road dust,24 seasonal samples and 18 inter annual samples of road dust were collected from roads in Shanghai,and were analysed by ICP-MS following aqua regia digestion.The results are as following: average concentrations of PGEs in spring,summer,autumn,winter were 10.40(6.06-17.28) ng/g,11.60(5.52-20.11) ng/g,32.91(18.53-61.05) ng/g,32.33(16.29-47.89) ng/g with Rh,52.99(27.48-100.2) ng/g,53.77(... |
