Abstract The paper gives results of a comparative study of variations in measuring and analytical techniques used to assess sources upon which emission factor data bases are built (in an effort to quantify these technique-dependent parameters). The study included a simultaneous, side-by-side field test with five independent testing organizations sampling dust emissions from an unpaved and uncontrolled road at a major steel producing facility. Each participant independently measured the particulate emission concentrations produced by the roadway traffic. These measurements resulted in not only particle-size dependence of the emissions but also concentrations as functions of the distance above the road surface. The results for each participant were expressed as emission factors for total particulate and the mass fractions of the particulate with size <30, <15, <10, and <2.5 micrometers diameter. The study showed that all five profiling systems were capable of producing equivalent results in terms of total emissions. This was not the case for emissions by particle size: the only technique found to produce reliable emission factors by particle size was inertial sizing.
