A study was performed that: (1) critically reviewed existing source emissions data to determine if variations in the organic composition of such emissions could be used to distinguish sources of airborne particulate matter and particulate organic matter; (2) attempted to develop receptor source apportionment models for three fractions of particulate organic matter and selected polycyclic aromatic hydrocarbons using an existing set of ambient aerosol measurements made at a site in New York City; (3) defined critical needs for the development of receptor models for airborne organic matter. The results of this study showed that it is possible to develop receptor source apportionment models for particulate organic species using the factor analysis/multiple regression modeling technique. It showed that a lack of adequate organic composition data for source emissions was a critical limitation for model validation and also for development of chemical mass balance receptor source apportionment models. It also showed, however, that existing source emissions data on polycyclic aromatic hydrocarbons and certain other species indicate that such species might be useful in distinguishing emissions from certain types of sources.
