Help!! Species Transport-Mass Fraction

anyone familiar with Street canyon problem might be able to help.
I am modeling carbon monoxide dispersion using species transport in Fluent.
I am specifying road surface as a Mass Flow Inlet from which CO is emitted (g/s). I am using Mixture Template (air-CO)
I know the CO emission rate which i specify (g/s)
Here is the question:
As the emission is of CO, I set CO mass fraction as 1.
upon convergence, I get very high conc of CO (10^-4 kmol/m3)
other researchers report this in the range of (10^-8 kmol/m3)
What might be the problem?
