Measurements of Some Trace Elements in Street Dust in Zilfi Province at Saudi Arabia Using Inductively Coupled Plasma-Mass Spectrometer

Dust has frequently been used as a material for monitoring trace elements polution . The wind may take the trace elements to the f arms. And we know that there are many farms around Zilfi Province., at Saudi Arabia . So in this study the concentrations of some trace elements(As,Cd,Cr, ,Pb, and ,Zn) , 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), after sieving and digestion using HNO3 , HCL and HF . Concentrations of most elements have been found less than allowed concentrations in literature , but the concentration of arsenic is found higher than the limit allowed specially in some samples . . The concentrations of , Cd , , Pb, Cr , and Zn , are high nearby car repair workshop and also at main streets especially in Hai Elsdeeg compared to Hai Smnan .
