Abstract
Aerosols were analyzed which were obtained in New York City, Great Smoky Mountains, in laboratory smog chamber facilities, and from primary automobile exhaust. The results indicated that certain organic chemicals were present in aerosols associated with auto exhaust which were not present in aerosols from rural atmospheres. On the other hand, at least one organic compound was present in aerosols from rural atmospheres which was not present in urban air aerosol samples. These results indicate that the presence of certain organic compounds in aerosol samples may indicate the origin of haze. The products from the photochemical reaction of NO2 and the aerosol samples were also analyzed.
