Abstract：In order to investigate the pollution situation and potential health risk of heavy metals in deposited dusts in the Ebinur Basin, which is a typical oasis experiencing rapid economic development in Xinjiang, northwest China, contents of heavy metals Zn, Cr, Hg, As, Pb, Cd, and Cu in deposited atmospheric dust samples were analyzed. Then by using enrichment factor (EF), Geo-accumulated index (Igeo), and health risk evaluation method to analysis, the results showed that the mean annual dust deposition amount was 298.23g/m2, the average monthly dust deposition amount was 24.85g/m2, and the dust deposition amount in winter season (2013-Aug-2014-Feb) was significantly higher than that in the summer season (2014-Mar-Aug). From the enrichment factor (EF) calculation, Cu, Cr, and As in the deposited atmospheric dusts in Ebinur Basin were mainly from a natural geological background, while Pb, Cd, and Hg were mainly influenced by the anthropogenic pollution.From the geo-accumulated index evaluation (Igeo), the non pollution levels for As, Cr, Cu, and Zn in every month accounted for the largest proportion, however the low pollution levels for Pb, Cd, and Hg were the most, and the moderate pollution levels also account for certain proportions. From the health risk assessment, the carcinogenic and non carcinogenic risks of heavy metals in the atmosphere dusts were relatively low, and won't cause harm to human health in the basin.
