Ninety-seven street dust samples were collected in a sampling period and 19 sites were revisited. Comparison between 97 sites and 19 revisited sites, using t-test and one-way analysis of variance (ANOVA), suggests that representative magnetic properties, and mean values of some element concentrations and the organic matter content may be obtained with a small number of samples from a sampling period of one or several days. Correlation analysis and factor analysis were applied to investigate associations between magnetic properties and between magnetic properties and element concentrations. The results suggest mixed contributions of magnetic material from urban and natural sources, probably mainly urban sources. Finally, this study may suggest a possible approach for source identification of magnetic material in pollution studies.
