TL;DR: The results indicate that street dust in Baoji has elevated heavy metal concentrations, especially Hg, Pb, Zn and Cu, which are 16-77, 7-92, 6-26 and 4-12 times the background levels in Shaanxi soil, respectively.

TL;DR: The results indicate that, in comparison with Chinese soil, street dusts in Baoji have elevated metal concentrations as a whole and IPI indicates heavy metals of street dust polluted seriously.

TL;DR: The results indicate no distinct pollution of Mn, Ni, As and Ba in the dust, while Cu, Co and Zn are moderate pollution, Pb is significant pollution, and Cr with large pollution range.

TL;DR: The location of point pollution sources and prevailing wind direction were found to be important factors in the spatial distribution of heavy metals and there was significant enrichment of Pb, Zn, Co, Cu and Cr based on geo-accumulation index value.

TL;DR: In this paper, the physicochemical properties and the contamination levels of mercury and arsenic in roadway dust from Baoji, NW China were investigated using an atomic fluorescence spectrophotometer.
