Abstract Several studies are currently being conducted to better understand spatial and temporal variation of PM2.5 in the Cincinnati metro area. First, a temporal interpolation model is applied to Cincinnati’s central air quality monitoring data. Results will be utilized by Cincinnati Children’s Health Medical Center in time-series epidemiologic studies. Second, several years (2008 – 2015) of hourly and daily PM2.5 data at seven continuous monitors over a four-county region have been analyzed to understand the importance of local-scale emissions and activity in impacting spatial differences in pollution concentrations. One particular focus is on transportation patterns, which can aid in better estimating exposure in activity-based models. Finally, we have been conducting several field campaigns at a near-roadway monitoring site operated by the local air quality agency. The goal of this research work is to characterize the concentrations of fine particulate matter air pollution (PM2.5), noise and PM2.5 metals content resulting from near-road transportation under varying traffic states at fine temporal scales. The results will provide insight into better understanding of near real-time composition of the metals composition of fine particulate matter.
