Abstract Details

2011, MS, University of Cincinnati, Engineering and Applied Science: Environmental Engineering.
The filter based methods have been “the gold standard” of PM measurement in spite of its cost and labor intensiveness. Meanwhile many continuous instruments have been employed side by side at many US sites, and the results from the continuous instruments have been used in forecasting air quality index and applications other than compliance. This goal of this study is to evaluate the data agreement of fine particulate matter (PM2.5) concentrations from filter based Federal Reference Method (FRM) and continuous instruments, such as tapered element oscillating microbalance (TEOM), and ß-gauge-nephelometers (BAM). The study was performed on five sites (Lebanon, Middletown, Batavia, Sycamore, and Taft) managed by the Hamilton County Department of Environmental Service (HCDOES), Ohio. According to EPA, PM2.5is considered as Class III. Class III included all methods related with PM2.5or PM10-2.5 samples from the atmosphere that are base in 24-hour filter sample. The monitoring period ranges from January 2004 to December 2010. The concentrations from continuous monitoring were averaged in 24 hours in order to compare with FRM. Also each data is three day data. To analyze the data a linear regression was performed between continuous and FRM monthly data and seasonal data. Thus, the intercept and the slope of the linear regression were put into an EPA template to evaluate the equivalence of the candidate method vs. the standard FRM. The same approaches were performed with all the instruments of HCDOES. Some continuous instrument exhibited higher correlation with the FRM than others. However, Seasonal changes such as winter and summer resulted in larger statistical differences, especially in March and October. Analyses also were performance such as multi linear and non-linear, where the temperature was part of the analyses.
