| Abstract: | Concentrations of suspended particulate matter (SPM) have been measured simultaneously in Baghdad, Iraq, using a high volume gravimetric procedure alongside a low volume sampler with smoke shade determination of OECD standard smoke. No correlation is seen between the gravimetric and smoke shade measurements, except when a single northwestern wind sector is taken. It is concluded that natural wind-blown dust constitutes the major source of SPM in Baghdad and that application of international air quality guidelines for SPM is problematic and probably inappropriate. |
