Fume emissions from coal-tar pitch. Technical manuscript
This study was intended to characterize the chemical and physical nature of coal-tar fumes emitted from spreading applications of coal tar and to determine a first estimate of the emission factor for coal-tar fumes under conditions similar to those found in the field. Three separate experiments were performed. The first resulted in the determination of a coal-tar fume particle size distribution. The second experiment resulted in the identification of the primary compounds found in collected tar fumes and a determination of their relative concentration. The third resulted in an estimate of coal-tar fume emission rates under various air flow conditions. These results may permit determination of the potential hazards to workers health and air quality associated with coal-tar-pitch products. (auth)
