The report gives results of a field program to establish a predictive model for PM-10 (particulate matter with diameters = or < 10 micrometers) emissions. (NOTE: Several areas of the U.S. in violation of the National Ambient Air Quality Standard for PM-10 have conducted studies that have identified the resuspension of antiskid material applied to paved roads as an important source of PM-10. The application of antiskid materials creates a temporary but substantial increase in the amount of fine particulate on the road surface over and above that which is normally present. Measured emission data are lacking for all types of antiskid materials.) A source-oriented emissions sampling procedure was conducted on a section of US 53 just west of Duluth, MN, during March/April 1992. The only general observation made was that PM-10 emissions appear to increase with the amount of antiskid material applied. A comparison of measured emission factors with those predicted by an EPA compilation of air pollutant emission factors indicated that most of the measured factors are higher than those predicted from silt-loading.
