Some Trace Elements in Zilfi Streets Dust

Dust has frequently been used as a material for monitoring trace elements pollution. The wind may take the trace elements to the farms. Zilfi Province is Located on Riyadh, capital of Saudi Arabia approximately 260 km North. And we know that there are many farms around Zilfi Province. So in this study the concentrations of some trace elements(Co ,V ,Ni ,Cu and K) , in streets dust in major streets and inner ones in Hai Elsdeeg and Smnan at Zilfi Province have been studied for comparison, using Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) ELAN 9000 (Perkin Elmer Sciex Instrumento , Concord ,Ontario ,Canada), after sieving and digestion using HNO3 , HCL and HF . Concentrations of most elements have been found less than allowed concentrations in literature, but Vanadium was a little less than the maximum concentrations allowed. The concentrations of Ni, and Cu, are high nearby car repair workshop and also at main streets especially in Hai Elsdeeg compared to Hai Smnan.
