Abstract
This study attempts to quantify, by means of published and unpublished data, the fractions of particulate emissions from major sources which is condensed matter unaccounted by emissions inventories. Very few reliable quantitative data were found. Most of the estimates in the report are based on front half/back half data from EPA Method 5 tests. The contractor estimates that 30 - 50 percent of point source particulate emissions in certain cities could be condensed matter. However, the reliability of these estimates is questionable because of an artifact problem. Thus, estimated emissions may be too high for some sources and too low for others. An appendix summarizes the data found.
