Comments on “Size Distribution of Organonitrates in Ambient Aerosol Collected in Houston, Texas” Aerosol Science and Technology, 36:983–992 (2002)

Abstract

A previous article in this journal reported the results of an FTIR analysis of the ambient aerosol collected during a field study in Houston, Texas during August and September of 2000. The emphasis of that article was on the organonitrates collected during the study. In the discussion of their research, the authors noted some discrepancies between the organonitrate absorbances observed in Houston compared to those seen in a previous study conducted in Los Angeles, California. They offer several explanations for the observed differences. In these comments, an alternative explanation is offered for these differences.
