英文摘要	In order to understand the compositions characteristics of particulate matter with aerodynamic diameter less than 2.5 mum(PM_(2.5) ) fraction in road dust(RD_(2.5) ) of oasis cities on the edge of Tarim Basin, 30 road dust(RD) samples were collected in Kashi, Cele, and Yutian in the spring, 2018, and RD_(2.5) was collected using the resuspension approach.Eight watersoluble ions, 39 trace elements and 8 fractions of carbon-containing species in PM_(2.5) were analyzed.Ca~(2 +) and Ca were the most abundant ions and elements in RD_(2.5)(7.1% and 9.5%).Cl in RD_(2.5) was affected not only by attributed to saline-alkali soils in oasis cities of the Tarim Basin and dust from Taklimakan Desert but also by human activities.Moreover, the organic carbon/elemental carbon(OC/EC) ratio indicated that carbon components in RD_(2.5) in Cele town mainly come from fossil fuel combustion, while those in Yutian and Kashi mainly come from biomass combustion.It is noteworthy that high Ca in RD_(2.5) was seriously affected by anthropogenic emissions, and high Na and K contents in RD_(2.5) could be derived from soil and desert dust.It was estimated that Cd, Tl, Sn and Cr were emitted from anthropogenic emissions using the enrichment factor.The coefficients of divergence(COD) result indicated that the influence of local emission on road dust emission is greater than that of long-distance transmission.This study is the first time to comprehensively analyze the chemical characteristics of road dust in oasis cities, and the results provides the sources of road dust at the margin of Tarim Basin.
