Ambient air samples were collected continuously from May 14-29, 1980 to determine if the emissions from a commercial Lurgi coal gasification plant could be identified downwind of the facility. Physical, inorganic, and organic analyses were carried out on the collected aerosol samples, and organic constituents were determined on the vapor-phase sample catches. The total atmospheric particle loading was higher immediately downwind from the Kosovo industrial complex that includes the gasification plant. Coal dust resulting from the handling, grinding and transporting of the coal was probably a major contributor to the particle burden. A very complex organic mixture was found in the vapor-phase and adsorbed on the particulate matter. Maximum individual concentrations were 8 micrograms/cu m for naphthalene in the vapor and 0.08 micrograms/cu m for the benzopyrene isomer group adsorbed on the particles. The naphthalene loadings were found to correlate positively with the percent of downwind sampling time. The GC-MS profile of organic compounds found in the ambient air samples also correlated well with those expected from emission sources at the gasification plant (represented by the middle oil, one of the coal gasifier's by-products). Thus the compounds found can be considered characteristic of the emissions from the Kosovo Lurgi coal gasification plant.
