University of Buffalo

Buffalo, New York

The objective of this study is to examine the relative concentrations of ultrafine particles in a residential neighborhood downwind of the Peace Bridge, which has previously been identified as an area having a high prevalence rate of asthma in children (Lwebuga-Mukasa and Dunn-Georgiou 2000). Because of extended periods impacted by idling or stop-and-go heavy diesel truck and automobile traffic, it had been thought that local source emissions may be related to these health issues.  The seasonal measurements collected provided great detail into assessing the locations of several ambient air quality fixed site locations including selection of several homes through hot spot analysis.  Further homes expected to have high ambient and mobile source emissions were further characterized along with comparison to fixed sites located in relatively close proximity (McAuley, et al., 2010, Indoor Air) as a result of earlier work (McAuley et al., 2010, AS&T).
